 Original drawings of my forge!
Here is the original drawings and patent # with the inventor's description. CLUTCHING DEVICE FOR FORGES - Google Patents I hope to finish 'restoring' it this weekend. Will sandblast, paint, and line the pan with a refractory. I do not have the hood as shown and the lever is mounted close to the pan. All else is as drawn. I think this is SO COOL!! Plan to post before and after pictures soon.

Don't you just love a patent server? Are you going to print it out and hang it somewhere? I don't know how many times I've found the device or mechanism I needed by searching them. Now Google has made it reasonable and easy to do. Congratulations Thomas. Frosty

I tried to print it out last night but it only want to print 1/2 page. I will have to wait until I can get to a real computer....

It took me a while to figure out what the heck a clutching device was then it hit me square in the face, or in this case, it wouldn't hit me in the face if I had the patented clutching device. I look forward to the photographs.

I'm a bit thick in the head today, what does it do? I was trying to figure it out just from the pictures, my brain doesn't want to deal with reading the technical description right now.

Larry, think of it is as a freewheel on a racing bicycle. Flywheel/pulley wheel "C" (rear wheel on bicycle) can spin on momentum even after if the lever "M" (pedals) is stopped. The clutch is the freewheel hub. That's the best I can do with my pea-brain on a Friday afternoon with a triple digit temperature outside. |

cool, that makes sense now. It's not triple digit's here but getting close today.

Larry, just to expand nett's explanation, the actual clutch mechanism is a pair of opposed direction, high single pitch screws that mate together when rotated in one direction, and part in the opposite direction. The screw attached to the lever is sprung to push onto the other, which is at a fixed depth but free to rotate (and thus transmit power furthre down the drive train). When the operator moves the lever down, the screws engage and the power is transmitted to the flywheel and the blower. Whenthe downwards movement of the lever falls below that of the second screw, the first screw is forced away, and the flywheel is allowed to continue turning as it will. The lever can of course be raised up again, also not affecting the speed of the flywheel. A very simple and effective solution.
