Davor Posted November 1, 2013 Share Posted November 1, 2013 I went to the scrap yard and bought 32 kilos of files and other blacksmithing tools, 11 files almost all big around 60 cm long (23 inches). It cost me around 20 euros or 25 dollars. But in with the tools was some sort of the crank tool thingy, well you can see on the pictures. So what is it? Maybe it’s not from a blacksmith’s shop but it was with all the other tools that obviously are. The small piece on the back is broken off.

Frosty Posted November 2, 2013 Share Posted November 2, 2013 You got it in one Davor! That is indeed a highly coveted hand crank thingy! Sorry, I couldn't resist joking a little. I'm afraid I don't know what it is but I'll sure be interested when someone who does speaks up. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Davor Posted November 2, 2013 Author Share Posted November 2, 2013 Well we have established what it is, now we need to find out what it does. :D Quote Link to comment Share on other sites More sharing options...
DSW Posted November 2, 2013 Share Posted November 2, 2013 Well we have established what it is, now we need to find out what it does. :D Drive the buyer nuts trying to determine a use for it? :D Quote Link to comment Share on other sites More sharing options...
Jakesshop Posted November 3, 2013 Share Posted November 3, 2013 Is it a right or left handed highly coveted crank thingy? Quote Link to comment Share on other sites More sharing options...
Tommy Traylor Posted November 3, 2013 Share Posted November 3, 2013 That is the best one of those I have seen in a long time. Quote Link to comment Share on other sites More sharing options...
rjs Posted November 3, 2013 Share Posted November 3, 2013 next step, carefully take it apart and see what is inside. Quote Link to comment Share on other sites More sharing options...
Davor Posted November 3, 2013 Author Share Posted November 3, 2013 next step, carefully take it apart and see what is inside. Not necessary. I turn the handle and the little piece on the back turns also. The handle has a big gear and the piece on the back a small one. Don't know the ratio, didn't count. I can turn it in both directions.

utaholdiron Posted November 3, 2013 Share Posted November 3, 2013 I've no idea what the tool was used for, but I did find the handle interesting. First off, the handle can pivot, and also it is offset (not straight). It would appear when the handle is as shown in the photos, when turning it would have more torque. Now flip the handle 180 degrees and when turned would it not be easier to rotate faster, but with less torque?The more I look at it I think the offset in the handle is merely so it doesn't hit the raised part of the smaller gear thingy as it turns.The prong thingy attached to the smaller gear looks to be replaceable. Maybe that was so different sized prong thingies could be used.All that being said, I think the machine was used to cut or scribe a hole in some sort of dense material such as glass or light gauge metal, etc. I could also be dead wrong!

John B Posted November 4, 2013 Share Posted November 4, 2013 IMHO It would appear to be a part off a Singer type sewing machine, The handle folds in to pack away in the carrying case. The unit is secured/bolted to the sewing machine base, and the drive engages in the (hand) wheel that gives the reciprocating motion for the needle's drive.

utaholdiron Posted November 4, 2013 Share Posted November 4, 2013 Foot powered sewing machines were common in their day, but I'm not sure there was ever a hand crank sewing machine. Quote Link to comment Share on other sites More sharing options...

utaholdiron Posted November 4, 2013 Share Posted November 4, 2013 John B, I stand corrected! Check out the link Harri posted. Thanks, Harrii, for putting this one to bed for us! Quote Link to comment Share on other sites More sharing options...
Frosty Posted November 5, 2013 Share Posted November 5, 2013 Oh yeah, the hand crank Singer is still the best selling sewing machine Singer made. One fits in a small suite case size case and doesn't take up near the room. Folk moving west didn't have room to spare, a treadle sewing machine was pretty high fallutin. My sister collects, restores and uses sewing machines of all kinds at least used to have a couple hundred of the things in various states of restoration. Knows the Singer info number by memory. The hand crank machines are unbeatable for embroidery. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...

My grandmother still has a foot powered sewing machine, I had no idea there was hand powered ones. :) Well I took it because I thought I could make something from it, maybe a small round stone grinder/sharpener.
