CHARLES RICHARDSON, OF PHILADELPHIA, PENNSYLVANIA.

TEMPORARY BINDER.

' SPECIFICATION forming part of Letters Patent No. 228,931, dated June 15, 188.0.

Application filed May 3, 1880.

To all ywhom it may concern:

Be it known that I, CHARLES RICHARDSON, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented an Improvement in Temporary Binders, of which the following is a specification.

My invention consists of a device, fully described hereinafter, for clamping together masses of separate sheets of paper in such a manner that any ofthe papers can be readily perused.

In the accompanying drawings, Figure is a plan view of my improved clamp for retaining loose papers; Fig. 2, a perspective view of part of the same, and Fig. 3 a transverse section on the line l 2, Fig. l.

Two strips, A and B, preferably of hard wood, a-nd arranged at right angles to each other, are connected together by two metal brackets, D D. To lugs a a 011 each bracket is pivoted a clamping-jaw, G, which in the present instance consists of two arms, b b, a connecting-plate, d, in front, and a cross-bar, e, all being preferably cast in one piece. To the two arms of the jaw, near the rear end ofthe said arms, is pivoted a nut, h, through which passes a set-screw, t', the lower rounded end of the latter being adapted to a socket formedin the bracket. The upper end ofthe screw has a square orilice or is otherwise formed for receiving a suitable key, by which the screw can be turned.

A spring, w, secured to the bracket and bearing against a pin on the jaw, tends to open the latter and to maintain the lower end ot' the screw in its socket. It will be seen,

` however, that while a spring for this purpose is desirable it is not indispensable.

Loose papers which it is desired to keep together are placed between the plates Z of the jaws and the projecting portions f, Fig. 8, of the bracket, the edges of the papers extending, if desired, as far as the lugs a, or as far as the margin of the papers will permit after which the screws are turned and the papers are thereby securely clamped.

(No model.)

I prefer to secure to the strip B, between the two brackets, an additional strip, m, ot' the same thickness and conformation as the end portions, j', of the brackets, so that there may be a nearly continuous bearing-surface for the papers.

It will be seen that the pivot-pin m is situated at such a point in respect to the jaw that there shall be the least possible drag of the end d of the jaw on the papers when the clamping of the latter takes place.

After the papers have been conned by the clamps one or more of the sheets of paper can be turned over for the purpose ot' examining and writing on the sheets beneath, the papers thus turned over bearing on the upper edge ofthe strip A, as indicated by the line y, and this strip being above the screws, so that the latter cannot interfere with or tear the papers.

rlhe two strips A and B, arranged at right angles to each other, and the metal brackets D D, adapted to the strips, constitute a very substantial frame, capable ot' etfectnally resisting the force exerted in closing the clamps on the papers.

I claim as my invention- 1. A temporary binder in which are combined the following elements-namely, the strips A and B, the brackets D D, by which the said strips are connected together, jaws Cr G, pivoted to the said brackets, and devices whereby the said jaws are. caused to clamp the papers and rigidly retain the same, all substantiall y as set forth.

2. The combination of a bracket, D, and pivoted jaw G, with a nut, h, pivoted to said jaw, and a screw, t', adapted to the nut, all sub stantially as described.

In testimony whereof I have signed myname to this specification in the presence of two subscribing witnesses.

CHARLES RICHARDSON.
