TEMPORARY BINDER.

Speccation of Letters Patent.

Patented Oct. 17, 1905.

Application filed January 16, 1905. Serial No. 241,309.

To all whom it may concern:

Be it known that I, THOMAS P. HALPIN,a citi- Zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Temporary Binders, oi' which the following is a specication.

This invention relates to temporary binders oi' that general type adapted to receive and hold loose leaves in book form and of such construction that the leaves in any number can be readily removed or inserted at will.

Among the salient objects ot' the invention are to provide a temporary binder capable of expansion and contraction by means of sectional binder-posts and or' such construction that the ends of the binder-posts do not project beyond the outer surface of the binder members, but are obscured therein, and to provide in a temporary binder a new and improved mechanism ior locking the adjustable binder member in adjusted position upon the posts.

The invention will be readily understood from the following description, reference being had to the accompanying drawings, in which- Figure 1 is a rear view of a binder embodying the present invention. Fig. 2 is a sectional view through the binder, showing the operating mechanism. Fig. 3 is a fragmentary sectional view taken on line 3 3 of Fig. 1. Fig. 4 is a similar view taken on line 4. 4., Fig. 1. Fig. 5 is an inside face view of the upper binder member. Fig. 6 is an inside face view of the lower binder member.

Referring to the drawings, 7 and 8 designate, respectively, upper and lower binder members, which, as shown, are of substantial thickness. These binder members are preferably made of wood, though it is obvious that they might be made of other material and that they need not be made solid.

9 designates a metal strip mounted upon the inner face of the lower binder member 8 and carrying two binder-

posts

10 and 11, said posts being of the sectional type and secured rigidly to said strip. The binder member 7 is provided at its ends with

openings

12 and 13, adapted to receive the ends of said binderposts, said openings being closed at the upper side of the binder member by a couple of metal plates 14 15, mounted thereupon and which constitute stops to prevent the ends of the binder-posts from passing through the binder member 7 Mounted upon the inner face of the binder member 7 is a springmetal plate 16, having therethrough the openings 17 18, adapted to pass over the binder-posts as they enter the openings in the binder member, said plate being slotted throughout the distance between said openings and the middle portions thereof sprung apart, so that they normally tend to expand the openings 17 18 in such manner that the posts pass freely therethrough. In order to clamp said plate to the binder-posts, said plate is provided with a couple ot' lugs or ears 19 20, mounted on opposite sides of the slot therein and connected by a key-screw 21, by means of which the two portions ot' said plate can be positively drawn toward each other for the purpose oi' clamping the plate to the binder-posts or released to permit them to move to their normal position, which releases the posts and permits the binder member 7 to move upon the posts a distance corresponding to the depth of the openings 12 13, which is suiicient to permit the binder memberv 7 to be pressed downwardly upon the loose leaves in the binder and securely locked in place by means of the locking-plate 16. the screw 21 projects through an opening in the rear edge ot' the binder member, as clearly shown in Figs. 1 and 1.

Each of the binder members 7 8 is preferably covered, as with leather or canvas, (designated 22,) the ledges or' which project forwardly, as at 23, Figs. 8 and 1, to receive the back or cover members 24 25. (Shown in fragment in Figs. 3, 4..)

It will be seen from the construction described that a binderis provided the outer surfaces of which are left smooth and uninterrupted by binder-posts projecting through the binder members thereof, that the posts are obscured when the leaves are in piace, an that the structure as a whole is neat in appearance and convenient to operate.

It is obvious that alterations and moditications in the details of construction and arrangement might be made without departing from the spirit of the invention, and I do not, therefore, limit the invention to the details here shown except in so far as they are made the subject-matter ot' specific claims.

I claim as my inventiond 1. A temporary binder comprising a pair of binder members, one of which is provided with straight sectional binder-posts, and the other of which is made of substantial thickness The key-receiving end ofl IOO IIO

and provided with transverse sockets telescopically engaging said posts and of a depth approximating the length of the sections of the latter, and mechanism for locking said binder members in adjusted position upon said posts, substantially as described.

2. In a temporary binder, a pair of binder members,one of which is provided with binderposts of uniform size and the other oi' which is provided with a self-contained socket for each post, into which said posts telescope adjustably, a locking-plate upon the face of said latter binder member and provided with eX- pandible post-receiving apertures registering with the open ends of said sockets, and means for positively expanding and contracting said apertures to lock said binder member upon the ends of said posts, substantially as described.

tions, a second binder member provided with self-contained sockets adapted to receive said posts telescopically, a locking-plate mounted upon said latter binder member and provided with post-receiving apertures registering with said sockets and slotted longitudinal ly between said apertures, and a screw arranged transversely of said plate and having threaded engagement with each portion thereof, whereby to positively expand or contract said apertures, substantially as described.
