SHEARS-AND SCISSORS.
APPLICATION FILED MAY 20 1918.
1,299,104. Patented Apr. 1,1919.
v INVENTOR ATTORNEY UTE AT -f a rnnr clarion (I ELISHA J. ARNOLD, OF RENSSELAER, NEW YORK, ASSIGNOR TO SCISSORS APPLIANCE I CO. INC., A CORPORATION OF NEW YORK.
SHEARS AND SCISSORS.
Specification of Letters Patent.
Application filed May 20, 1918. Serial No. 235,510.
:. county of Rensselaer and State of New York, have invented certain new and useful Improvements in Shears and Scissors, ot which the following is a specification.
My invention relates to improvements in shears and scissors, and the object of my invention is to provide an instrument of this general type in such a form that it may be used in many classes of work with much greater efliciency than the types now available; together with such other elements and combinations as are hereinafter more particularly set forth.
I accomplish these objects by the device illustrated in the accompanying drawing, in which:
Figure 1 is a perspective view of the entire device.
Fig. 2 is a perspective view of the spring and attachments.
Fig. 3 is a perspective view of the cover for the spring.
Similar numerals refer to similar parts throughout the several views.
In textile and allied industries where shears or scissors are used to clip or cut thread and yarn ends from garments in the process of finishing, the operator grasps an ordinary pair of scissors by the blades, pinches them together with the thumb and forefinger to make the cut and separates them again for the next cut by the use of the thumb and fingers.
My shear is especially adapted for use in this manner. No part of the operators fingers need project below the blades, thereby permittingthe shear to be brought very close to the work in an essentially parallel plane, and the blades automatically opening after each cut will greatly increase the speed of operation.
1 and 2, represent the principal moving members or blades having cutting edges, 3 and 4:, respectively. The blades are pivoted at the back by the screw, 5, which is secured in blade, 2.
The screw, 6, secured to blade, 2, passes through a slot, 7, in blade, 1, and holds the shearing edges together.
Aflixed to the forward outside edge of each blade near the point is a projecting piece, 8, on blade, 1, and a similar project ing piece, 9, on blade, 2, set at right angles to said blades, designed to form grips for the thumb and fingers of the operator.
The spring, 10, is wound to any required tension about the screw, 5, and is designed to automatically open the blades after each cut. One end of spring, 10, is attached to screw, 5, secured to blade, 2, and the other end is attached to blade, 1, by a pin, 11, inserted therein.
The cover, 12, is set over the spring, 10, protecting and holding it, and is secured by the screw, 5. 1
While I have described my shears in the form in which I prefer to construct them, I desire it to be understood that changes in minor details not inconsistent with nor outside the scope of the appended claim may be made.
What I claim as my invention and desire to secure by Letters Patent is:
A pair of shears or scissors having blades pivotally connected at one extremity by a screw rigidly attached to one of them; a sliding connection centrally disposed between the pivot and the points of the blades and designed to hold the cutting edges together; a spiral spring, designed to keep the blades normally separated, coiled about the pivoting screw having one end secured in a slot therein and the other end secured to a pin in that blade to which the pivoting screw is not attached; and projections on the outer edges of the blades near the points forming finger grips, all substantially as described.
In testimony whereof I have aflixed my signature in the presence of two witnesses.
