  • still looking for an answer...

    hey everyone. yes im still looking for anyone that knows about that silly little ball wheel conversion that slows the wheel down, puts a finger on it, and eliminates lift rod covers for good. my tech trainer thinks its a good idea. even though id like to take credit, someone beat me to the punch, and spiked it. [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img] now im stuck with a quicktime movie, and a real anxious tech trainer lookin to dig his fingers in an get dirty. (yes people, it does happen every once in awhile...)if you need to see thew video, e mail me for a request at bsmith3915@juno.com
    if i had two pennies, i could rub them together...

      Re: still looking for an answer...

      As far as I know, ballchaser is now defunct.

      There was a design flaw in the product, in that the device attatched to the ball wheel was stationary.

      Since the lift rods are stationary, the ball MUST be allowed to roll against the ball wheel ... think about it ... the reason there were no covers on those rods is that if there were, the ball wouldn't have been able to slide up the rods (it couldn't rotate because of the device attatched to the ball wheel ... so it had to slide ... right?? That would almost be guaranteed to put scratches/burn marks into anything but the old rubber stones)

      Any new version of the ballchaser type of gizmo would need to incorporate some type of roller so the ball could rotate while being run up the rods ... but that's only my opinion.

      Another trouble spot I could see is how many pins is that puppy gonna toss up into the track ... kinda resembles a shovel on a GS machine ... doesn't it??

        Re: still looking for an answer...

        When I saw that video, I told myself, that I had to have one. The problem was that I wasn't willing to shell out the 350 bones they were asking, and I just couldn't see welding something to my ball wheel. If it were to cause more problems than it cured, then the it would cost more than the modification to replace a ball wheel.
        I put some thought into it, and came up with a no weld design. I designed it to allow the ball to rotate as it is carried up the lift rods. I also made it with a low enough profile to clear the shaft that supports the motor. I have made a wooden model, slowed down the ball wheel, and done some preliminary testing with the model. So far everything looks good. I am currently waiting for the material to make the "Lift Dog". I expect it at my front door at any time. My biggest concern is durability. How well will it hold up when a ball or pin comes through the cushion really hot? That question will be answered soon enough.
        One side note. Slowing down the ball wheel has had one positive side effect. I have not had a pin in the ball track since slowing it down. Even if my modification doesn't work out, I think I will keep that part of it. Imagine a world where you never have to pull up the capping to get a pin from under the floor!

          How exactly did you slow down the ballwheel? i have been interested in doing this myself just for the fact of keeping pins out of the tracks

          and then he said, "on your death bed, you will receive total consciousness" so I got that going for me...... which is nice!

            Re: still looking for an answer...

            that was the question i was asking.......doh!!
            ive been picking this over, bit by bit and for the life of me, i can't figure out how to slow it down without disrupting the pit conveyor. i reeled at the idea of slowing it down, but cursed the after effects, namely slow pin transfer. i have a copy of the video, and the pit seems to work in the same way as it normally would, so what gives? is there some holy grail of belt and conveyor ratios that i havent found yet? or am i just peeing into the wind?


            if i had two cents, i could rub them together..... [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

              Re: still looking for an answer...

              I used a 3.75" diameter pulley to drive the ball wheel. I mounted a idler pulley to the 7 side guide roller to take up the extra slack and to keep it from rubbing on the HD guide roller. Speeding up the pit conveyor took a little imagination. The only 1/2" bore pulleys I could find had the collar for the set screw. Can't exactly put a nut on that to hold it to the idler arm. I ended up using a bushed bore pulley with a 1/2" split taper bushing. As you tighten the screws on the bushing, it clamps itself down on the 1/2" shaft on the idler arm. I had to tap the bushing on to the idler arm as I tightened it because tightening it tends to draw it away from the idler arm. The machine I have done this to has ran since October, and the pulley hasn't come loose at all. I am currently using a 5.95" pulley to drive the pit conveyor. It runs slower, but is adequate. I did raise the front of the pit conveyor less than 1/2" below the flat gutter(not reccomended for people with picky inspectors), and lowered the rear(they were already too high). I have enough room under the new pulley, that I can increase the size of it by almost 3/4". My only concern about doing it is that I may have to fabricate a longer shaft for the idler pulleys. I don't know if any of you actually saw the website, but it gave away lots of information about how much they slowed things down. I am WAAAAAAAY into slowing things down. I have also slowed down some of my cross conveyors and turrets. The biggest benefit I can see from doing it is that it creates less wear and tear.

                Re: still looking for an answer...

                Well, it's not exactly a holy grail ...

                Drive RPM x drive Pitch Diameter = Driven RPM x Driven pitch diameter is the formula for precise results, you can use the OD of the pulleys for a not-so-precise result. Pitch diameters of given OD pulleys can be found in the grainger book.

                Here's what I did ... note that this is for jetback, A2 might need different pulleys:


                Elevator drive pulley on motor is 3.5 (jetback)
                Ball wheel drive pulley BK32 (grainger 3X852, 3.2")
                Pit drive pulley Browning BS27 (2.7")


                I made an extension arm for the spring post on the ball wheel idler to keep tension on the ball wheel belt, reason being, I have Cable triggering for the gearboxes, and I could not pull the belt upward, i had to pull down (spring that pulls cable for gearbox triggering was in the way of going upward)

                As far as the math on the pulleys to get the ratio right:

                pit drive size/ball wheel drive size is ratio you want to maintain ... Since we want the RPM of both shafts to stay the same ...

                Original brunswick ratio:
                4.375 divided by 5 = 87%

                my drive ratio:
                2.7 divided by 3.2 = 84%

                since pit ratio on mine is lower, pit actually runs a sniff faster than "normal" on mine, but not visible to naked eye. My first try was a BS 26, which gave an 81% ratio, and that was too fast for my liking.

                When I first tried it, I used my 3.2 pulley with the 4.375 stock pit, which was 136%, didn't shake worth a damn [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

                The BS series of pulley is solid steel, and just wide enough for a B width belt. The only hitches you'll run into are that you'll have to locktite the idler nut, as you can only get 3-4 threads of bite (pulley doesn't have a recessed/undercut hub like the brunswick pulley)

                If you find a pulley you like for the ball wheel speed, a pit pulley that's about 85% of that size should do well to keep the pit speed right. Masternut left his pits alone, but I wanted my pits running the same speed they did originally.

                And be advised that a small (.2") change in the diameter of the pit pulley will make a LARGE difference in the pit speed. Smaller pit pulley will make the pit run FASTER ... it's the DRIVEN side. Smaller Ball wheel pulley will make ball wheel run slower ... it's the DRIVE pulley

                You may need to experiment some, but the above should get you close ... and now my ball wheels run about 20 rpm versus close to 40 before the conversion. That should DOUBLE the life of belts, guide rollers/bearings, etc. Not only that, but even the 6# balls will never leave the track on the odd lane, so no more CC pulley dings in balls. They just come up, roll off the top gently, no problems

                  I have always used a Gates no hub pulley (set screw in the groove) then take a 1 1/8" end mill and mill down to the set screw hole. This provides a full set of threads for the nut on the driven pulley.

                    Forgot to add to previous post. One must use a star lock washer ( or equivalent ) between the bearing and the pulley to provide outer race clearance, in other words, the pulley will rub on stationary part of bearing.

                      Roscoe:

                      Good points, well taken. If I had access to a milling machine, I'd bore them out. (I guess I did a fair job of explaining the ratio conversions??? [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] )

                      The BS series by browning is also a solid, hubless unit, which would take to the same treatment. And they are available in 1/10th inch increments in the range of sizes most mechs would be interested in ... what I like to see speed=wise might be somewhat different than what others might prefer.

                      Roscoe is also correct on needing a spacer of some sort to get the pulley away from the bearing's outer race ... but if not mentioned, the first time you tried to spin it, you'd find out in a hurry ... I did [img]/content/btubb/images/%%GRAEMLIN_URL%%/eek.gif[/img] :p

                          Abstract:
                          A one piece positive contact bowling ball retriever device, having no moving parts. It is secured to the inside of the ball return wheel and circum rotates with the wheel. It has a lead finger guide designed to assist in the differentiating of pins and the ball, as the pins go their way the lead finger guide captures, guides and holds the ball in its concave radius to be lifted and deposited in one smooth continuous flowing motion for subsequent discharge into the bowling ball return. This positive contact device nether contributes to nor is it affected by slippage and drag caused by the oil and dust normally associated with automatic bowling machinery. By using this positive contact device, ball friction will no longer have to be artificially supplied by the use of temporary rubber ball kickers and the machine r.p.m.s can be reduced for longer equipment life and more economical operation. Ball retriever 1 eliminates the need for manufactures to friction compensate by operating at 36 r.p.m, this inventor suggests that the bowling machinery may now be operated at a lower r.p.m using belt and pulley reduction, however, other speeds and means of speed reduction could also be used.

                          Description:


                          CROSS-REFERENCES TO RELATED APPLICATIONS

                          [0001] None

                          STATEMENT AS TO RIGHT TO INVENTIONS MADE UNDER FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT

                          [0002] Not Applicable.

                          BACKGROUND OF THE INVENTION

                          [0003] The field of the invention is generally that of a positive contact bowling ball return device and more specifically to a convexo-concave ball retrieving apparatus so fabricated as to capture, guide, lift and deposit in one smooth continuous flowing motion, a bowling ball for subsequent discharge into a bowling ball return. In the bowling industry there are certain mechanical malfunctions directly associated with the operation of automatic bowling machinery these problems are most commonly referred to as spinners, Yo-yos and lane stoppages. It is these machinery malfunctions that constitute a meaningful overhead cost to the industry, these unnecessary problems result in a loss of revenue due to equipment downtime, bowler inconvenience, frustration, loss of customer satisfaction and the added cost for providing the personnel whose time would be better spent for other maintenance.

                          [0004] In reference to the Brunswick automatic pinsetter bowling machine, in particular models A and A2 which constitute a major percent of the bowling market, the bowling ball automatically finds its way for deposit onto the ball return wheel. It is at this time that the malfunction called spinning occurs. When the large static mass of a round bowling ball, excess oil on the ball and a lack of friction meet a continuously moving ball return wheel, moving at approximately 36 R.P the bowling bail will take the path of least resistance and just sit there and spin. It is this same lack of friction that causes the ball to yo-yo or malfunction in another location of the ball return path. The environment inherent to the operation of automatic bowling equipment is naturally oily, dirty and subject to electrostatics which act in concert to attract even more dirt, it is this oil and dirt that introduces slippage and drag and acts as a deterrent to maintaining a constant friction for a smooth, efficient, trouble free and timely bowling ball return. It will be appreciated by those skilled in the art that to insure that a large mass bowling ball will be return routed, through automatic machinery without slippage or drag, requires a precise amount of applied friction.

                          [0005] It is an observation of this inventor that it has been indeed difficult, for manufactures, to achieve and maintain this correct amount of friction due to the constantly changing machine environment of oil and natural wear and the large mass of the ball. Prior art has superficially approached this problem of friction, mass and the phenomena of spin by applying three thin strips of carpet or belting material to the ball return wheel, held in place by adhesives and by increasing the r.p.m. of the automatic machinery. Application of this disposable ball kicker, by prior art, provides inadequate and only temporary friction as the tape very quickly again becomes saturated with oil creating a potential fire hazard, becomes ineffective and must be continuously disposed of in land fills. Typical costs to the operators for three eighteen inch strips of tape per machine, in a fifty-lane bowling alley, could be in excess of two hundred dollars per month and than must be replaced.

                          [0006] It will be appreciated by those skilled in the art that this one piece stand alone ball retriever device, having no moving parts, that captures, guides, lifts and deposits in one continuous flowing motion eliminates the need for disposable ball kickers and other ball return aids having moving parts.

                          [0007] It will be farther appreciated by those skilled in the art that this one piece positive contact device will no longer require the higher machine speed of 36 R.P.M., it can now be operated at approximately 1/3 the R.P.M. thereby reducing the ball wheel revolutions, excessive wear on the guide rollers, flanges, drive belts, bearings, pulleys, reducing ball and pin damage, extend machinery life and will result in an overall energy saving. It is another observation of this inventor that the ball lift rods will no longer have to be manufactured with a rubber coating to provide friction as the lead guide finger of this device capture and holds the ball in a concave radius, applying a constant pressure against the back ball lift rod. It is a further observation of this inventor that due to the ball retriever one piece simplicity it could ultimately be incorporated into the manufactures fabrication of the ball return wheel.

                          SUMMARY OF THE INVENTION

                          [0008] The present invention is a one piece structure having no moving parts that when secured to the ball return wheel captures, guides, lifts and deposits in one smooth continuous flowing motion, a bowling ball for subsequent discharge into a bowling ball return. This positive action device provides the integrity of a constant friction against a bowling ball on its return path through automatic bowling machinery, it being impervious to slippage caused by lubricants and drag caused by dust and dirt. This device eliminates the need for disposable ball kickers and other ball return aids having moving parts and allows the automatic machinery to be operated at a lower r.p.m. thereby extending machinery lifetime and for a savings of energy.

                          [0009] It is an object of the invention to provide the user a device that reduces automatic bowling machinery downtime and a subsequent loss of revenue by eliminating spinners and ball hang-ups regardless of how much oil is on the ball.

                          [0010] It is another object of the invention to provide the user a one piece device, having no moving parts, that eliminates the need for disposable ball kickers and other ball return aids having moveable components.

                          [0011] It is a further object of the invention to provide the user a more environmentally friendly device that eliminates the need for the disposal of oil soaked rubber ball kickers and carpet strips into land fill areas.

                          [0012] It is another object of the invention to provide the user safer operation of automatic bowling machinery by eliminating a potential fire hazard posed by the presence of oil saturated kicker strips.

                          [0013] It is a further object of the invention to provide the user a device that reduces the excessive wear on automatic bowling machinery such as bearings, guides, belts and drives by allowing the user to operate the equipment at a lower r.p.m.

                          [0014] It is another object of the invention to provide the user a more energy efficient operating system by allowing them to operate at a lower r.p.m.

                          [0015] It is a another object of the invention to provide the user a device that reduces bowling ball and pin damage by allowing them to operate at a slower r.p.m.

                          [0016] It is a further object of the invention to provide the user a device that helps speed bowling pins on the rear of the pit conveyor into the pin elevator thereby reducing the setup time of bowling pins.

                          [0017] It is a further object of the invention to provide the user a device that eliminates the expense and danger of using hazardous cleaning materials and eliminates the time required by a mechanic to clean the ball return wheel.

                          [0018] It is another object of the invention to provide the user a device that reduces mechanical downtime thereby saving the expense of replacing expensive bearings on rollers and pulleys.

                          [0019] It is a further object of the invention to provide the user a field upgrade kit to slow down the automatic bowling machinery to facilitate smoother operation and provide longer machinery lifetimes.

                          [0020] Further objects are implicit in the detailed descriptions which follows hereinafter (which is to be considered as exemplary of, but not specifically limiting, the present invention) and said objects will be apparent to persons skilled in the art after a careful study of the detailed descriptions which follows.

                          [0021] For the purpose of clarifying the nature of the present invention, one exemplary embodiment of the invention is illustrated in the hereinbelow-described figures of the accompanying drawing and is described in detail hereinafter. It is to be taken as representative of the multiple embodiments of the invention which lie within the scope of the invention.

                          BRIEF DESCRIPTION OF THE DRAWINGS

                          [0022] FIG. 1 is a perspective view showing one exemplary embodiment of one representative form of the invention.

                          [0023] FIG. 2 is a perspective view showing one exemplary embodiment of one representative form of the invention.

                          [0024] FIG. 3 is another perspective view showing one exemplary embodiment of one representative form of the invention.

                          DESCRIPTION OF THE PREFERRED EMBODIMENTS

                          [0025] Referring to FIG. 1. Bowling ball retriever 1 is a positive contact singularity base, that is to say, it is a one piece contact device having no moving parts. Ball retriever 1 is secured to the ball return wheel 6 with pop rivets 2, however other means of securing or fastening may also be used. The bottom 7 of ball retriever 1 is configured convex to physically comply with the inside radius of the ball return wheel 8, however that is not to say that another bottom configuration could be used if required by another form of fastening. The lead guide finger 9 of retriever 1 is designed to retrieve the ball, differentiating between ball and pin, to guide, capture and house the ball in its concave leading edge 10 for lift and delivery for subsequent discharge into a ban return. The ball, held in the radius of the lead guide finger 11 applies the correct amount of pressure against the back ball lift rod 12 eliminating the need for the rubber friction compensator. The leading edge 13 of ball retriever 1 is of a particular radius, however, other shapes or radii could also be used. The top trailing edge 14 of ball retriever 1 is of a angle for easy deposit of the ball into the ball return at the top of the ball lift, however another shape or angle could also be used. Ball retriever 1 eliminates the need for the manufacture to friction compensate the ball return system by operating at 36 r.p.m, this inventor suggests that the bowling machinery be now operated at a lower r.p.m. by using belt and pulley reduction, however, other means of speed reduction may also be used. Elongated front angled edge 3 expedites the separation of the bowling ball and bowling pins for a faster ball return system. The second angle top rear 4 facilitates easier discharge of bowling ball onto the ball return rails 15. Recess 5 secures the bowling ball for delivery to the ball return rails 15. Impact cushion 16 is attached to the impact sides of ball retriever 1 with adhesives however that is not to say that other means of fastening may also be used, the function of impact cushion 16 is to assist in diverting the ball and to lesson the stress placed on the fasteners 2 used to attach the ball retriever device 1 to the ball return wheel 6. Ball protector lip 17 insures against ball damage due to occasional high speed impact, ball protector lip 17 is shaped by the forming process of ball retriever 1, however other means of ball protection may also be used. One or more impact cushions (16) or other configurations and compositions may also be used however that is not to say that other means of bowling ball protection may also be used.

                          [0050] 8. #E142) to run approximately 1/3 of it's normal speed while keeping the

                          [0051] 9. other Brunswick components running at or near their standard speeds.

                          [0052] 10. Referring to Reference sheet 4 The speed reduction consists of the changing

                            "the hoof" kicker works, as i have seen it on one or two machines.
                            But, what happens when balls get backed-up on the even machine??
                            does the "hoof" break off?
                            or does it simply stop the ball wheel?
                            do you get ball damage?
                            do pins damage the part?

                              This kit is not cheep. It's about $500 per machine. I have 1 in a 40 lane center, it works as promised but the cost of $20,000 makes it prohibitive. I have slowed down my ball wheels by about 10 R.P.M.'s for about $55 per machine and works quite well.
