Description: |
| Abstract:
The object of my invention is to devise a reverse and variable cut-off, which will permit of the the widest possible range and accuracy of cut-off, which will reverse quickly and which is simple in construction and reliable in operation and consists, essentially, in operating the valve connecting rod from the crank disk pin on a slide adjustable on a suitably driven crank disk and provided with means whereby its position on the disk may be changed at will, while the parts are in motion.
Claim:
In mechanism for the purpose described, a slide having a wrist pin on which is thereon on which is journaled the valve connecting rod in combination with a disk having guides thereon in which the said slide may move: a suitably journaled sleeve on which the said disk id fast; means for revolving the said sleeve from some moving part; a shaft within the sleeve; a connection between the shaft and the slide whereby the latter may be moved by the turning of the shaft. |
