Description: |
| Abstract:
It is the object of my invention to produce a machine of increased efficiency with respect to the means for varying the stroke of the ram or like moving part of metal planing ma- chines, it being highly desirable in this class of machines designed for rapid work that the stroke of the ram or like moving part be changed quickly and accurately without necessitating the stopping of the machine. My invention therefore consists of automatic dogs and arrangement of the slides which carry the dogs for operating the shifting mechanism and in the means whereby said slides and dogs may be speedily and accurately adjusted and securely held in their adjusted position without the use of a wrench or other tool.
Claim:
In combination with the ram the bar extending longitudinally thereof and having teeth, the dog slides movable over said bar, the pinion engaging the bar, the pinion shaft journaled in the slide and movable longitudinally therein, the spring for forcing the pinion normally inward into engagement with the bar, and the means for locking the pinion against rotary movement consisting of a handle having teeth and the teeth on the slide substantially as described. In combination with a slide movable thereon, a bar having teeth, a pinion engaging therewith, a shaft on which the pinion mounted capable of rotary and limited reciprocating longitudinal movement, a handle to draw the pinion out of engagement with the bar having inclined teeth on its inner end, teeth reversely inclined on the opposing face f the slide and a spring to return the pinion into engagement with the bar . |
