POWER-LEVER.
SPECIFICATION forming part of Letters Patent No. 433,978, dated August 12, 1890.
Application filed May 29, 1890. Serial No. 353,582. (No model.)
To all whom it'may concern:
Be it known that we, DAVID CORNING and CHARLES H. SPRAGUE, citizens of the United States, residing at Danbury, in thecounty of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Power-Levers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to novel improvements in levers, whereby a great power is obtained when worked; and it consists in the construct-ion and arrangement and combination of parts, as will be hereinafter fully described.
The annexed drawings, to which reference is made, fully illustrates our invention, in which- Figure 1 represents our invention applied to a punch, and Fig. 2 isa side view showing the device applied to the levers of a powerinachine. Fig. 3 is a plan, and Fig. 4 is a de tail.
Referring by letter to the accompanying drawings, a designates the power-lever, at the inner end of which we journal two rollers 19 b, and between which rollers is a slot 0, formed in the end d of said lever. A bolt 6' passes through this slot and serves as a pivot for the end of the power-lever, and the ends of said bolts have their hearing in the side plates f f. Between these plates the lever a and a lever g, fulcrumed at h, is pivoted, and a stationary lever 1, connected between said plates by bolts jj. The upper fulcruined lever h is provided with an inclined inner end, as at 70, upon which the upper roller works, and the lower stationary lever 2' has also an inclined portion Z, which the lower roller in the powerlever acts upon when said lever is operated.
It will be seen that when the lever a is lowered the same turns upon its bolt or pivot, the lower roller moving forward and up the incline of the lower lever, while the upper roller at the same time moves rearwardly and against the beveled or inclined portion of the upper fulcrurned lever. Thus when said lever a is operated, the outer ends of the two jaws come together or toward one another, the rollers in the end of the lever a passing over the inclined planes on each of the jaws;
and it will be further observed that our power-lever can be used for different purposes, and the same can be used with steam or other power, and it is durable, and cheap to manufacture.
Having described our invention, what we claim, and desire to secure by Letters Patent, is
1. The lever a, pivoted at its inner end at e and provided with rollers 19 b, journaled on opposite sides of the pivotal point and arranged at right angles to said lever, and the jaws g 2', having the inclined planes 70 Z, upon which said rollers are adapted to roll, substantially as described.
2. The combination of the jaws,-one of which is pivoted, the handle or lever a, rollers b b, journaled at the inner end thereof, and the pivotal bolt-connecting said lever to the side plates ff, substantially as specified. In testimony whereof we affix our signatures in presence of two witnesses.
