Description: |
| Within a few years the patentee was manufacturing machine tools under his own name. Some of his early machine tool designs were manufactured by Wood, Light & Co.; we do not know whether that firm, or anyone else, manufactured this crank planer.
Abstract:
In crank-planers and other similar machines, it is often desirable to reduce or increase the throw of the crank, to give a greater or less motion to the table of the planer, or whatever is to be moved by the crank; and he nature of my invention consists in mechanism so constructed that the operator can change the throw of the crank as may be desired, without stopping the driving mechanism, and without affecting the stability and strength of the crank-connection.
Claim:
The combination, with a crank-planer or like machine, of mechanism substantially as herein described, for regulating the throw of the crank without stopping or interrupting the continuous operation of the machine. |
