george m. Posted August 25, 2014 Share Posted August 25, 2014 Dear All, I recently picked up this grinder at an auction. I have absolutely no idea how it was used. It is heavy enough (11 lbs.) that you can't really use it as a hand held device. There is a sort of peg or tab on the bottom of the frame, just behind the grinding wheel which might have gone into a slot on some sort of support but it looks a little fragile for something made of cast iron. There are remains of black paint and it originally had nice 19th century looking gold pin striping on the frame. There is no info regarding the manufacturer but there is a plate regarding patent information (May 18, 1885) and other countries in which it is patented. If nothing else, it has a cool gadget factor. Thanks, George M. Quote Link to comment Share on other sites More sharing options...
jeremy k Posted August 25, 2014 Share Posted August 25, 2014 Looks like an old cordless hand grinder to me. Hold it in your left hand and crank with your right, and the stone wants to crawl away from you so you can control it with your left hand to keep it on the area you want to grind. Like I said - looks like an old cordless hand grinder to me. Quote Link to comment Share on other sites More sharing options...
DSW Posted August 26, 2014 Share Posted August 26, 2014 You sure it's not an antique circus unicycle? Hold the one handle doing a hand stand and crank the 2nd with your other hand to propel you around the ring... With the stone wheel maybe it's from the Flintstones! :P Quote Link to comment Share on other sites More sharing options...
jkmas Posted August 26, 2014 Share Posted August 26, 2014 keep it away from the front of your pants. Quote Link to comment Share on other sites More sharing options...
ForgeMan32 Posted August 26, 2014 Share Posted August 26, 2014 Man that thing makes you appreciate the old dewalt angle grinder in a whole new fashion . It would have to be soft metal to grind and you would have arms of steel after working that modified cake mixer all day long Quote Link to comment Share on other sites More sharing options...
ausfire Posted August 26, 2014 Share Posted August 26, 2014 Seems to me with gearing like that, the wheel would be fair whistling. And held in the left hand and turned with the right it would seem to want to travel towards you. Looks like an unpredictable beast to me.

jeremy k Posted August 26, 2014 Share Posted August 26, 2014 I got it wrong. It must be for left handed ppl :) After a closer look the spark guard proves what hand to hold it in. Quote Link to comment Share on other sites More sharing options...
LEGION66 Posted August 26, 2014 Share Posted August 26, 2014 Nice one, try to make hand crank blower out of this, whats gear ratio? Quote Link to comment Share on other sites More sharing options...
Stash Posted August 26, 2014 Share Posted August 26, 2014 Kinda looks like what would be used to grind down RR track welds. How big is the beast? Steve Quote Link to comment Share on other sites More sharing options...
george m. Posted August 26, 2014 Author Share Posted August 26, 2014 In response to the queries: It is 19 3/4 inches long. The stone is 6 inches in diameter. There are 3 sets of 30 tooth and 15 tooth wheels. If I recall how to calculate gear ratios that is only 16 to 1. That doesn't seem like much to me for that much weight and machinery. Of course it is reversible depending on which way you turn the handle. I agree that RR rail welds could be ground with this except that they weren't welding rails in 1885. It does seem to lend itself to grinding things on the ground. I wonder if it might have been used in either boiler making of ship building. How it ended up on a farm in NE Colorado is as big a mystery as the tool itself. Curiously, George M. Quote Link to comment Share on other sites More sharing options...
