What is it?

This gear box doesn't have any name on it. It mounts up against some sort of table. There must have been some sort of clamping mechanism on the bottom that has broken off (bottom of second photo). The two fingers sticking out would have supported it on the top side of the table. There are a couple short studs sticking out that would have went into holes in the table (bottom of second photo). The output shaft on top of the unit is pretty small in diameter (third photo).

It?s been awhile since I?ve seen one but it sure looks like my uncles hand grinder. It clamped to a bench. It was more fun to play with than to use as I recall.
 
Definitely a hand powered grinder. Missing the wheel and arbor nut/washres, the handle for the crank, and the bottom 1/2 of the table clamp. Jim
 
I agree with hand cranked grinder. There's one out in our barn that my wife said she cranked before she started grade school. Our kids and grandkids cranked it too. A kid never tires of cranking that thing. It'll drive you nuts after an hour or so, ha.

Ours still has the orange paint on it.
 
The crank handle goes to a large gear which spins the small gear for the grinding wheel very fast. Mount a stone and use it .
 
I also say a hand crank grindstome. Were made to take from a 3" grinding wheel up to a 8" depending on model. But it is missing half the parts. It is a 2 person job to use one of those things, one to hold object to be ground and one to do the grinding. Over the years I have gotten dozens of them for the Amish I work with. But they have gone out of favorite now for just the arbor to mount 2 wheels on with a V-belt driven off a gas engine. Price at flea markets has not gone down tho. and anouther item I don't have to look for for them.
 
I thought perhaps it was a hand crank grinder, but the arbor looked really small in diameter for a grinding wheel. I also have one of the arbor type 2-wheel grinders. Dad had it mounted on a long narrow table. Motor on one end and the grinder on the other. Not sure why he had it mounted that way. Maybe the only V-belt he had was a really long one.
 
The smaller grinding wheels do have a smaller center hole and then there is bushings bade for that purpose. Those arbor grinders I have had 2 of them and the one with both a coarse and fine grindine wheel. The other with the wire wheel. Liked them better than the bench grinder with the built in motor, perhaps because they did not run as fast. They all are leaving now as I am having to get rid of everything.
 
I'm with Steve the fan drive with crank off from and old forge for blacksmith work. We had one till the bottom rotted out. Worked great for straightening out larger pieces with less time heating.
