SPROCKET-WHEEL WRENCH.
SPECIFICATION forming part of Letters Patent No. 643,520, dated February 13, 1900.
Application filed December 26, 1899. Serial No. 741,672. (No model.)
To all whom it may concern.-
Be it known that I, CHARLES H. MONROE, of Searsport, in the county of Waldo, State of Maine, have invented a new and useful 5 Sprocket-Wheel Wrench, of which the following is a specification.
The object of my invention is to design an implement that can be readily manipulated to force on the sprocket-wheel shaft a sprocket- IO wheel in such a manner that the same will remain on said shaft in a fixed manner and also capable of removing said wheel at the will of the operator, which I attain in the following manner:
In the accompanying drawing, A represents the hand-lever, aits hand manipulating portion, and a the heel portion of the said lever, which is provided with the teeth a and intervening spaces a for the purpose of effizo ciently engaging the teeth on the sprocketwheel. The heel portion of the lever is slightly on an angle to the arm portion of the lever, the purpose of which is to establish an angle of convenient leverage when the instru- 2 5 ment is put to use, which is illustrated by the drawing.
B denotes a portion of a sprocket-wheel chain, one end of-which is pivotally connected to the heel portion of the lever at a point a little distance from the end of the heel portion, as is clearly shown in the drawing, and the other end of said sprocket-wheel chain is free to swing. This chain is of ordinary construction and, as shown in the drawing, com prises sufficient links to permit anefficient engagement with a sprocket-wheel.
1) represents thelinks. 1 and2 respectively denote sprocket=wheel teeth and spaces of the sprocket-wheel 3. v The length of the lever can be any desired length, according to the amount of force desired,depending upon the nature of the Work. Also the length of the chain may be made longer than shown in the drawing, if desired.
The following is the manner in which this invention is used: To rigidly fit the sprocketwheel to its shaft, the operator first engages the sprocket-wheel chain with the teeth of the sprocket-wheel in the manner shown in the drawing. Then he positions the heel of the lever so as to engage a tooth of the sprocketwheel. When this is done,the operator then takes up the slack that might be existing after such positioning, and then by forcing upon the lever the wheel can be thus drawn on the shaft to the point desired. When the wheel is to be removed, all that the operator has to do is to reverse the tool and apply the force, as before mentioned.
Having described my invention, I claim- A sprocket-wheel wrench consisting of a hand manipulating-lever having its fulcrum end slightly angular to the arm portion of the lever, teeth provided on said fulcrum end designed to engage the teeth on a sprocketwheel, a sufficient length of a sprocket-chain having one end pivotally connected to the heel portion of the lever at a point a little distance from the end of said heel portion, and the other end of the sprocket-wheel chain free to swing and be positioned, substantially as described. I
In witness whereof I have hereunto set my hand to this application this 19th day of December, A. D. 1899.
CHARLES H. MONROE.
