Description

UNTTED STATES PATENT OEEICE sAMUELN. EORTNEY, OE JEFFERSON TOWNSHIP, MONTGOMERY COUNTY,
' OHIO.
SHEARS'.
SPECIFICATION forming part of LettersPatent No. 709,478, dated September 23, 1902.
Application led March Z9, 1902. Serial No. 100,588. (No model.)
To all whom it may concern,.-
Be it known that I, SAMUEL N. FORTNEY, a citizen of the United States, residing in Jefferson township, in the county of Montgomery and State of Ohio, have invented certain` A is a stationary supportingfbracket, con
sisting of a vertical plate, the lower part of which is secured to a bench or other fixed object.
B represents the shearblades,provided with crossed handlesc and d, which are pivoted together by a pin h. The lower handle c is longer than the upper handle d.
D is a bell-crank operating-lever, which is pivoted by a pin e to the rear end portion of the upper handle d. The long end of the bell-crank lever projects in front of the shearblades, and its shorter end or arm f projects rearwardly over the end of the lower handle c.
E is a link which is pivoted to the end portion of the lower handle c by a pin g and to the arm f of the bell-crank lever by a pin h.
Each handle c and d :is provided with two similar bolt-holes "i, spaced at the same distance apart, and j represents bolts which pass through holes in the upper part of the bracket A and secure to it whichever handle is found most convenient. When the lower handle c is secured to the bracket, the upper shearblade remains stationary; but when the upper handle d is secured to the bracket the lower shear-blade remains stationary. The connection of the handles with the bracket can be changed to suit di'lferent kinds of work and the judgment and convenience of the operator.
The bracket A is made of sufcient height to give plenty of room for the lower handle to work when the lower shear-blade is held stationary.
What I claim isv The combination,with a pair of shear-blades having crossed and pivoted handles each provided with two similar bolt-holes z' spaced at the same distance apart, and lever mechanism for operating the said handles; of a flat supporting-plate secured in a vertical position and having bolt-holes at its upper part corresponding with the said holes i, and two bolts which pass through the said bolt-holes and connect the said handles interchangeably with the said plate, substantially as slet forth.
` In testimony whereof I affix my signature in presence of two witnesses.
SAMUEL N. FORTNEY.
