HARLOW F. CAMP, OF AUSTINVILLE, IOWA.
SHEARS.
SPECIFICATION forming part of Letters Patent No. 697,232, dated April 8, 1902.
Application filed July 17,1901.
To all whom it may concern.-
Be it known that I, HARLOW F. CAMP, a citizen of the United States, residing at Austinville, in the county of Butler and State of Iowa, have invented certain new and useful Improvements in Shears; and I 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 shears for cutting iron and other metals; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
In the drawings, Figure 1 is a side view of the shears. Fig. 2 is a plan view of the shears. Fig. 3 is a detail View of the eccentric. Fig. 4 is a cross-section taken on the line as a; in Fig. 1.
A is the main frame of the shears, which is provided with feet a, by which it is secured to any suitable support.
B is a lever pivoted to the frame A by a pin Z).
O and D are the cutting-blades, which are bolted to the frame and to the lever, respectively, so that they can be removed when desired for the purpose of grinding or repairing them.
E is an eccentric which is journaled on a pin 6, which projects from the frame A. This eccentric is arranged under the rear end por tion of the lever B, and it is provided with a long operating-handle e. A curved slot f is formed in the face of the eccentric which comes next to the frame A, and a vertical and a slightly-curved slot g is formed in the side of the frame A opposite to the slotf.
H is a bar which is slidable in the slot g and which has a projection at each end. The projection h at the upper end of the bar H engages with a hole in the side of the lever, and the projection h on the lower end of the bar H engages with the curved slot f of the eccentric.
Serial No. 68,605. (No model.)
The metal is cut by the shear-blades when the handle is depressed, and the upper blade is raised by moving the handle in the reverse direction. WVhen the handle is moved in the reverse direction, the bar H draws down the long arm of the lever B. The projections of the bar engage loosely with the eccentric and the lever, so that no strain is placed on the bar when the handle is depressed.
What I claim is 1. The combination,with a main frame, and a lower shear-blade secured at its front end; of an operating-lever pivoted against the side of the said frame, an upper shear-blade secured to the front end portion of the said lever and working against the lower shear-blade, an eccentric pivoted to the rear end portion of the main frame and provided with a handle which projects forwardly over the said blades, and means for holding the rear end portion of the said lever in contact with the said eccentric, substantially as set forth.
2. The combination, with a main frame provided with a projecting pivot and a slot at its rear end curved concentric with the pivot, and a lower shear-blade secured to the front end portion of the said frame; of an operating-lever mounted on the said pivot and having a hole in its rear end portion, an upper shear-blade secured to the front end portion of the said lever, an eccentric pivoted to the rear end portion of the main frame and provided with a curved slot in its side and an operating-handle, and a removable bar which is slidable in the said curved slot of the frame and provided with projections at its ends which engage respectively with the hole of the lever and the slot of the eccentric, substantially as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
