SPECIFICATION forming part of Letters Patent No. 635,409, dated October 24, 1899.

Application iiled May 20,1897. Serial No. 637,434. (No model.)

particularly to temporary binders adapted foruse in connection with loose-leaved ledgers and account-books, order-books, samples of stock, and the equivalent thereof; and the object in view is to provide a simple, inexpensive, efficie11t,and readily-manipulated device adapted for arrangement to secure together loose leaves at one edge, whereby the opposite edge isleft free, thus enabling the several samples or leaves to be inspected without disarranging the binding, and, furthermore, to provide a binder which is capable of adjustment, whereby samples or leaves may be removed or added and the device adapted to suit the diminished or increased thickness.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claim.

In the drawings, Figure 1 is a perspective view of a temporary binder constructed in accordance with my invention applied in the operative position to a bundle of leaves or samples so arranged as to form a note-book or order-book. Fig. 2 is a detail view in perspective of the binder detached. Fig. 3 is an enlarged vertical section taken in the plane of one of the locks. Fig. 4 is a detail transverse section of the same enlarged, showing in full lines the position of the pin as when inserted into the socket and in dotted lines the position thereof when turned through an arc of ninety degrees to cause engagement of its rack with the threads of the socket. Fig. 5 is a detail View, detached, of the pin.

Similar numerals of reference'indicate corresponding parts in all the figures of the drawings.

The binder comprises,essentially, front and rear strips 1 and 2, adapted to be arranged in contact with the opposite surfaces of a bundle or collection of sheets, leaves, samples, or

similar separate articles to be bound, the rear strip being provided with socket -tubes 3, which extend forwardly through registering perforations previously formed in the articles and the front strip being provided with openings 4 to register therewith, and locking devices, consisting of headed pins 5, extending rearwardly through said openings in the front strips and en gaging the socket-tubes to secure the strips in the desired relative position.

The socket-tubes are attached rigidly to the rear strip and are inieriorly threaded or serrated except at one point, where the threads or serrations are cut awayby the formation of a groove 6 to produce a smooth or plane surface. The locking-pins are also threaded or serrated, as shown at 7, to form arack, of which the teeth have a pitch corresponding with the pitch of the threads in the socket-tubes. The width of each rack is equal to the plane surface of the socket-tube in which it is fitted, whereby the introduction of the pin to the desired depth to bring its fiat bearing-head 8 in contact with the exterior surface of the front strip may be accomplished by one movement and without turning the pin. In order to lock the parts in this position, the head is turned to bring it in the plane of the strips, as shown in Fig. 1. This turning of the pin causes the engagement of its teeth with those of the socket-tube, and hence secures the parts against displacement, and the pitching of the threads enables the locking devices, after the initial approximate adjustment of its members, to draw the strips together by screw action, and thus firmly compress the parts or articles comprising the book or bundle. The threaded portion of each sockettube cross sectionally preferably covers a distance of approximately three-fourths the circumference of the tube, while, obviously,

`the rack or toothed portion of the pin is proportionately of smaller extent, as not exceeding one-fourth of the circumference of the pin, whereby therotary adjustment of the pin to cause compression of the articles utilizes the pitch of the interlocking threads through an arc of two hundred and seventy degrees or more.

` Various changes in the form, proportion, and the minor details of construction may be IOO resorted to without departing from the spirit or sacrificing any of the. advantages of this invention.

Having described my invention, `what I claim is- A temporary binder comprising opposite strips, socket-tubes carried by one of the strips, openings in the other strip with which said tubes are adapted for alinement, said tubes having corrugated inner surfaces with the corrugated portions non continuous around the same, and lockingpins adapted to be passed through the openings in one strip and into the tubes of the other strip and having eorrugations upon their outer surfaces adapted for engagement and disengagement with the eorrugations of the tubes as the pins are rotated, said corrugated surfaces being non-eontinuous around the pins, and a head carried by eaeh pi n and adapted to lie upon the strip having the openings, and ush with the sides thereof, When the eorrugations of the pins are engaged with the corrugations of the tubes, and said heads being adapted to lie transversely of the strip having the openings, and project beyond the side edges thereof when the corrugated portions are disengaged, whereby when the eorrugations are engaged, accidental displacement of the pins may be prevented, and When the corrugated portions are disengaged, the fingers may be inserted' beneath the heads to withdraw the pins.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
