  • Guards & Covers

    Speaking of OSHA stuff... I've always wonderred this, and I've spent more time tonight inside the manuals than I care to mention... but the random thought comes to mind:

    At the top of the detector and gearbox assemblies are mounting bosses for ...something..... (The thing you usually put your hand on for balance whilst sitting on the machine...) It seems to me there must have been some kind of cover or hoods for the detector and gearbox at some point in their lives. I've never seen or even heard of such critters, but I still wonder. Anyone heard of 'em? I've always dreamed about fabricating something to that affect to keep the dust out of the cams and detectors, but like most projects, it's still in the dream stage. Did these originally have guards up there? Or are those mounting bosses there for another reason? I bet OSHA would have a hay-day with all the guards and warnings that these machines are all missing.

    Ever notice the cover of the Bruns. A2 service manual's binder, shows a pic of the machine butted up against a ~brick wall~... Hate to be the sorry @%$$#^ recoverring a ball out of ~those~ lift rods! OSHA would not approve

    The bosses on top of the detector were for a micro-switch which on the REAL old "A" machines, would black out the machine on an out-of-range. Unsure of when the design was changed, but it was before the 20,000s

      There was also a reset solanoid mounted on one of the bosses. I have worked on rear wall machines. The out-of-range lever and electrical buss comes out the front. The catwalk is hinged and you have to put a spliced ball wheel belt on. They were developed for bowling centers that had pinboys because there was little room behind the lanes when they converted them to automatics.

        I have seen photos of the gearbox with a lid & hinged door assembly that all coverd the gearbox and the detector. The main part of the shield/cover was bolted over the top of the gearbox and the rear end would lift to access the clutch. It also covered the 2:1 unit also. I think the idea was to protect from slipping and falling onto of the 4:1 crank & sweep link while in motion.
        ( and I used to run on the rear catwalks from one end of the house to the other )
