SHEARS.

SPECIFICATION forming part of Letters Patent No. 444,983, dated January 20, 1891. Application filed July 10, 1390. eel-a1 No. 358,230. (No model.)

To a'l/Z whom it may concern.-

Be it known that I, EMIL KRUSIUS, of So lingen, Germany, have invented a new and useful Improvement in Scissors, of which the following is a full, clear, and exact description.

The invention relates to that class of scissors in which a spring is provided with a view of maintaining the cutting-edges of the blades in proper relation, even when the blades become loose on their pivot.

The object of the invention is to improve scissors of this character with respect to both neatness and efficiency.

To this end the invention consists in the novel construction and combination, as hereinafter particularly described, and defined in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of scissors embodying my invention. Fig. 2 is a perspective view of the spring-plate, and Fig. 3 is a side view of said spring.

In constructing scissors in accordance with my invention I arrange an interposed plate a between the members I) b of the scissors at the pivot 0 thereof. The plate a is formed with an arched or spring portion a, and with an aperture a at the front of such arched portion, for the passage threthrough of the pivotscrew 0 of the scissors. The rear end or defining edge of the plate a is formed to approximate the form of the central portion of the scissors-blade on which the spring is rested, the object being to have the exposed portion of the plate conform to the blade or handle in order to give the spring as little prominence as possible.

At the rear end of the plate a there is formed thereon a projection a that extends at a right angle from the body portion thereof, or approximately so, and the said projection (L3 is received in a corresponding recess or depression b in the member of the scissors on which the plate a is seated. Thus the projection a maintains the plate in position at one end, while the pivot-screw c of the scissors performs a like office at its front end.

It will be seen that with the spring portion of the blade located in the rear of the pivot c the same will exert all its force, or essentially all, to maintain the cutting-edges of the blade in proper close relation, instead of acting to press the members of the scissors, in cluding the handles, bodily toward each other. By this construction, therefore, the pressure of the spring is utilized to the maximum extent and the scissors present a neat appearance, the arrangement making the spring to be unnoticeable.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. As a new article of manufacture, the plate a, formed with an arched or spring portion a, terminating in a lateral projection a and an aperture or opening a through the plate in front of said spring portion a, substantially as shown and described.

2. The combination, with scissors, of a spring plate interposed between the members thereof, said plate having an aperture through which the pivot-screw of the scissors passes, and having a projection fitting a recess of one of the members of the scissors, substantially as described.

EMIL KRUSIUS.
