JOHN G. DE COURSEY, OF PHILADELPHIA, PENNSYLVANIA.

-SGISSORS To all 'whom t may concern.'

Be it known that I, JOHN G. DE CoURsnY, of the city 'of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Scissors; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention consists of two blades similar to those of ordinary scissors, two springs, a knife blade, and a spring catch, the whole being constructed, combined, and operating substantially as described hereafter and forming a new manufacture applicable to many useful purposes.

In order to enable others to make and use my invention I will now proceed to describe its construction and operation.

On reference to the accompanying draw ing which forms a part of tliisJspecification Figure l is a face View of my improved spring scissors with the blades closed. Fig. 2, the same, with the blades open. Fig. 3, an edge view, and Fig. t, a sectional View on the line l, 2, Fig. 2.

Similar letters' refer to similar parts throughout the several views.

A and A are two blades of the same form as those of ordinary scissors, and are connected together by the screw pin a in the usual manner.

The arm of the blade A is jointed to the spring B and the arm 2) of the blade A is jointed to a similar spring B the tendency of the two springs being to maintain the blades open in the position illustrated in Fig. 2.

The outer ends of the springs are connected together and to the two plates C and C (the latter being situated between the two springs) by the pins or rivets (Z and e, a blade similar to that of an ordinary pen knife being hung to the pins e and arranged so as to bear against the spring F which is situated between the plates C and C and secured to the inner ends of the same, the spring with the two plates thus forming a recess for the reception of the blade when the latter is closed.

To the spring B near the point where it is hinged to the arm B of the blade A is jointed a spring catch G (Fig. 2) having three projections 7L and z' and j, and an ori-` lice adapted to fit over a projecting pin 7c on the opposite spring B.

The blades of the scissors are operated by holding the springs B and B between the forefinger and thumb and by a repeated pressure of the said springs toward each other.

When the instrument is not required for use as scissors, the spring catch G is moved (by applying the linger to the projection j) until its projection z' comes in contact with the joint of the arm b so that on closing the blades A and A the pin 7c will pass into the hole of the spring catch which will retain the blades in the closed position, until they are again required for use, when the catch is released from the pin ,7c and moved back until its projection L comes in contact with the oint Z2, the blades are then at liberty to be operated by the pressure of the springs B and B as before.

Although the above described instrument is as applicable for general use as a small pair of ordinary scissors, it is especially well adapted for use by operators of sewing machines, for the reason that in using my spring scissors the hand is situated at such a distance from the blades, and the position of the lingers is such that the blades can be operated in places inaccessible to ordinary scissors held in the hand in the usual manner.

I claim as my invention and desire to secure by Letters Patent as a new article of manufacture- The blades A and A, springs B and B, knife blade E and the spring catch G or its equivalent, the whole being constructed, combined, and operating substantially as and for the purpose herein setforth.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing Witnesses.

JOHN G. DE COURSEY.

HENRY HowsoN, CHARLES D. FREEMAN.
