Description: |
Abstract:
The main objects of this invention are to facilitate the adjustment of the length and position or limits of the stroke of the ram, to change the speed of the ram and in changing from one speed to another to avoid breaking or injuring the driving-gears; to automatically feed the work-supporting table crosswise in relation to the travel of the ram or tool; to provide for vertical adjustment of the table without affecting the adjustment or operation of the cross-feeding connections to automatically feed the table in either direction crosswise of the path of the tool when the tool is not cutting; to rigidly support the cross-head in different vertical positions, and thereby prevent sagging of the table in front, and generally to improve the construction and operation of this class of machines.
Claims:
1. In a crank-planer the combination with a reciprocating ram, of a crank-wheel for operating said ram, a crank-pin connected with said ram and mounted eccentrically upon a shaft which is revolubly fitted in said crank-wheel eccentric thereto and parallel with its axis, a gear-nut threaded on said shaft for locking said crank-pin with relation to said wheel, a similar gear mounted on and adapted to turn said shaft for adjusting the crankpin toward and from the center of said crank-wheel, and an operating-gear adapted to mesh with and to turn said gear-nut and movable into and out of mesh with the other gear, substantially as described.
2. In a crank-planer the combination with a reciprocating ram, of a crank-wheel having a journal on one side and an eccentric beveled seat on the other, a beveled friction-disk fitted to said seat and provided on one side with a crank-pin for actuating said ram and on the other side with' a shaft extending through said journal eccentric thereto and capable of rotary and endwise adjustment therein, a gear-nut threaded on the outer end of said shaft next to the outer end of said journal, a similar gear splined on said shaft adjacent to said gear-nut, and a gear carried by said journal in position to mesh with said gear-nut and movable into and out of mesh with the other gear, substantially as described.
3. In a crank-planer the combination with a reciprocating ram, of a crank-wheel pros vided on one side with a journal and on the other side with a seat, a friction-disk fitted to said seat and provided on one side with a crank-pin for actuating said ram and on the other side with a shaft extending through said journal parallel with its axis and capable of rotary and endwise adjustment therein, a gear-nut threaded on said shaft for clamping said disk against its seat, a similar gear mounted on said shaft, an operating-shaft revoluble and movable endwise in said journal coaxially therewith and provided at its outer end with turning means, and a gear mounted on said operating-shaft in position to mesh with said gear-nut and movable into and out of engagement with the other gear, substantially as described.
4. In a crank-planer the combination with the ram, of a crank-wheel having a journal on one side and an eccentrically-disposed seat on the other, a friction-disk fitted to said seat and provided with a crank-pin for actuating said ram and with a shaft movable endwise in said journal parallel with its axis, a gear nut threaded on said shaft, a similar gear mounted and held against turning on said shaft, a shaft carried by said journal parallel with the first-mentioned shaft and provided with a gear which is adapted to mesh with said gear-nut and is movable into and out of mesh with the other gear, and a cover attached to said journal and inclosing said gears, said shafts projecting through said cover and being provided one with an index and the other with turning means, substantially as described.
5. In a crank-planer the combination of a longitudinally-slotted ram having beveled sides, a clamping-plate having opposing parallel faces beveled to fit over and to engage with the beveled sides of the ram, a pivothead fitted to the under side of the ram and having a threaded stem which projects upwardly through the slot in the ram and a hole in said plate and is provided above said plate with a clamping-nut, and an actuating-crank connected with said head, substantially as described.
6. In a crank-planer the combination of a longitudinally and vertically slotted ram having beveled sides and vertical walls at the sides of the slot, a clamping-plate having parallel grooves fitting the beveled sides and the vertical walls of the ram, a pivot-head fitted to the under side of the ram and having a threaded stem passing upwardly through it and the clamping-plate and provided above said plate with a nut, and an actuating-crank connected with said head, substantially as described.
7. In a crank-planer the combination of a reciprocating ram, a crank-wheel for operating the same, a vertically-adjustable crosshead, a table movable on said cross-head transversely to the travel of the ram, a feed-screw carried by said cross-head and engaging a nut on said table, a pawl and ratchet-wheel carried by the cross-head for turning said feed-screw, a horizontal rock-shaft carried by the cross-head and having a crank connected with said pawl, a vertical shaft having a stationary bearing and connected with said rock-shaft by bevel-gears which are carried by said cross-head and one of which is movable up and down on said vertical shaft, a cam connected with said crank-wheel and a lever operated by said cam and connected with a crank-arm on said vertical shaft, substantially as described.
