UNITED STATES PATENT OFFICE.
AMOS WEST, OF PONTIAC, MICHIGAN.
IMPROVEMENT IN WORKING-POWER FOR SAWING.
Specification forming part of Letters Patent No. 49,575, dated August 22, 1865.
To all -whom t't may concern:
Beit known that I, AMos WEs'r, of Pontiac, in the county of Oakland and State of Michigan, have invented certain new and useful Improvements in Vorking-Power Applicable to Sawing and Other Machinery; and I do hereby declare that the following is a full, clear, and exact description ot' the construction and operation ofthe same, reference being had to the accompanying drawings, in which- Figure l represents a perspective view of a sawing-machine to which my working-power has been applied.
To enable others skilled in the art to make and use my improvement, I will proceed to describe its construction and operation.
A represents the main frame of the machine. B represents the driving-pulley or balancewheel, and O, D, E, and F represent belt-pulleys, which operate the crankshaft g of the machine, which latter operates the saw G by means of the crank 7L and pitman H. K represents a crank-pin, which is secured to the driving-pulley B, and L represents a lever, which is pivoted to said crank-pin. The short arm of the lever L has its bearing` on a stationary pin, a, which is secured to the main frame of the machine, and said short arm is provided with a slot, b, so as to permit the lever L suttlcient play in a horizontal direction when it is operated.
In operating my working-power the long arm of the lever L is raised and depressed alternately, which motion results in a rotary motion ofthe wheel B and its crank-pin K, and the necessary horizontal motion caused by the revolution of the crank-pin is obtained by the sliding of the short armof lever L on the stationary pin a, which passes through the slot b of said lever.
Thus it will be seen that by this arrangement the power necessary to operate the inachine can be greatly reduced by using a lever L of the desired length. This cannot be done in using an ordinary crank, as such a crank becomes very diftlcult to operate when it exceeds a certain length.
Another advantage iu my arrangement is that when the lever L is operated by hand the raising and depressing ot' the same is not as 'atiguing to the operator as the turning` of a crank, Where the entire body has to follow more or less the rotary motion ot' the crank-handle; but the operator can stand erect, and by using a lever ot' a suitable length he can work the machine with facility.
Having thus fully described the nature otl my invention, what I claim herein as new, and desire to secure by Letters Patent, is-
In combination with the crank-pin K, the lever L, pivoted to said crank-pin and supported on the stationary pin a, which passes through the slot b ot said lever, as and for the purposes specitied.
AMOS WEST.
