Description: |
| The inventor, Orril Reuben Chaplin, is best remembered for the Chaplin's Patent hand plane as manufactured by Tower & Lyon, patent 126,519, but he was granted a couple of dozen additional patents, for ball bearing journals, axle boxes, clutch, lawn mowers, shoe nails, and this metal planer.
Abstract:
My invention relates to improvements in metal-planing machines, and it is carried out as follows: I use, in the combination with a rocking frame or plates bolted together by studs, upon which the gears are held in position, and which frame is automatically rocked at the end of each stroke of the bed-plate, intermediate gears, and two additional gears in the rear of said rocking frame, so arranged as to run in opposite directions, and two half- gears secured to an independent shaft, for the purpose of imparting a half-revolution movement to the cross-feed shaft, so as to automatically move the cutting-tool forward at each end of the stroke. In combination with the aforesaid rocking frame and its gears, I employ a stationary bar or stop, against two opposite sides of which projecting ears on the rocking frame alternately strike when the said rocking frame is shipped, for the purpose of preventing the gears from bottoming into each other, and thereby creating unnecessary friction. The projections on the rocking frame are provided with set-screws, by which the exact rocking motion on said frame can be obtained and regulated.
Claim:
The combination of the rocking plates, s, s the pinions, zn, uc z, x, the half-gears, zv", x", the wheels, o, p, and intermediate gears, v v', rockshaft, y, and the head or block r. |
