CHARLES L. REPASS, OF WEST IPITTSTON,

EENNSYLVANIA, ASSIGNOR OF ONE-HALF 'IO HENRY E. SMITH, 0F SCEANTON, PENNSYLVANIA SHEARS.

Specification of Letters Patent.

Patented July 6, 1920.

Application filed September 12, 1919. Serial No. 328,250.

To cZZ whom it may concern:

Be it known that I, (Jr-mums L. Rnrnss, a citizen of the United States, residing at lVest Pittston, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Shears, of which the following is a specification.

This invention relates to shears, and more particularly to shears employed in splicing moving picture film.

The primary object of the present invention is to provide shears capable of making parallel cuts in a film, simultaneously, with one operation of the shears.

A further object oi the invention to provide means on one oi the arms of the shears, for supporting the film and holding the same flat, while the same is being cut, or repaired.

A still further object of the invention is to provide means on one end of the arms, of the shears, for scraping the emulsion from the film, preparatory to making the patch, or splice.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the in vention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

Referring to the drawing Figure 1 illustrates a perspective view of shears constructed in accordance with the present invention.

Fig. 2 illustrates a sectional view taken on line 22 of Fig. 1.

Fig. 3 illustrates a sectional view taken on line 3-3 of Fig. 1, and

Fig. 1 illustrates a sectional view taken on line 1- 1 of Fig. 1.

Reterring to the drawing in detail, the reference character 5 designates the hand hold of the shears, the same being in the form of a loop, and provided with the head 6, formed integral therewith.

The head 6, has a curved surface 7, which corresponds to the inner curvature 8, or the opposed pivoted element of the shears, to be hereinafter more fully described.

Openings 9, are provided in the head 6, to

receive the securing means 10, which are in the form of screws, but it is to be understood that suitable bolts may be employed if so desired.

The cutting blades 11, include relatively long knife-like members, provided with openings registering with the openings 9 in the head 6, for accommodating the securing means 10.

The outer ends of the cutting blades 11, are curved as at 12, in order that the sharp ends of the ordinary construction of blade, would not pierce, or otherwise disfigure the film under operation.

Cooperating with the blades 11, is a pivoted member 13, which is provided with an integral thumb hold let, formed at one end thereof, the opposite end thereof being substantially long, the same terminating at a point adjacent the free ends of the blades 11, to form a relatively flat supporting member 15.

Between the supporting member 15, and the thumb hold 14:, is an enlargement .16, which is provided with openings to receive the threaded member 17, forming the pivot pin between the two elements of the shears.

A relatively flat cutting blade 18, is suitably secured to the upper surface of the supporting member 15, and extends substantially the entire length thereof, the front end of said member 18 extending downwardly at an angle with relation to the supporting member 15, the extreme end there of lying in-a plane horizontal with the supporting member 15, as at 19. I

As shown, the member 19, is provided with a cut-out portion 20, provided with beveled edges 21, which beveled edges are designed to facilitate the scraping of the emulsion from the film, preparatory to the patching or splicing operation.

In view of the fact, that in the event that it becomes necessary to patch or splice a film, it is imperative that the continuity as well as the symmetry of the pictures be preserved in order to prevent the picture from being misframed, when projected on a sheet, the lines severing the picture from the strip, to be spliced, therefore must be parallel.

It will therefore be seen that the device as illustrated by applicant, will absolutely insure parallel cuts being made in the film, since the cutting blades 11 are disposed a predetermined distance apart, to insure the same'making'proper cutsto remove a'single picture'of the strip. 7

While I have shown and described my invention, especially adapted for operatingon picture films, it is of course to be under stood that the same may be employed for various uses by lengthening or shortening the distance between the blades.

Having thus described the invention, What is claimed is Shears including opposed pivoted mem hers, a pair of spaced parallel cutting blades forming'a part of one of the pivoted members, a thumb hold having a relatively Wide supporting member formed integral therewith, the free end of thesupporting member terminating in a plane equal to the plane of the ends of the cutting blades, a relatively fiat cutting blade of a Width equal to the Width of the supporting member, secured to the supporting member, said relatively flat blade having an offset outer extremity extending beyond the plane of the ends of the parallel cutting blades to provide a support, said relatively flat blade adapted to operate between the parallel blades.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence oftwo Witnesses.
