ROBERT J. BUCHANAN, OF PITTSBURG, PENNSYLVANIA.

TEMPORARY BINDER.

SPEGIFICATIUN forming part of Letters Patent N o. 683,019, dated September 24,

Application filed January 8. 1901. Serial No. 42.4.84. (No model.)

To ttZZ whom it may concern.:

Be it known that l, ROBERT J. BUCHANAN, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful' Improvements in Temporary Binders, of which the following is a specification.

The object of my invention is to providea temporary binder for loose sheets of paper, such as ruled sheets, adapted for the entry of memoranda or records of business transactions.

In carrying out my invention I provide a cover comprising two iat pieces connected by a flexible back. Within the iiexible back I secure two strips. to which I apply improved locking devices. Impaling-pins of improved construction are carried within the cover and are adapted to receive loose sheets of paper which are perforated or provided with eyelet-holes adapted to pass over the pins.

In the accompanying drawings, Figure 1 is a plan view of the inside of a book-cover or temporary binder with myimprovemen-ts applied. Fig. 2 shows a transverse section therethrough on the line 2 2 of Fig. 1 with the cover partly closed; and Fig. 3 is a detail view in section, showing particularly the locking devices employed.

The cover consists of two stiff boards A B, connected bya iiexible back C. The boardsA B are hinged to the back at a b, and the back is provided with strips D E, to which the locking devices are attached. The strip D is recessed at CZ, and within this recess is arranged a sliding bolt e. This is made iiat and slotted at e. Through the slot extend guide-screws e2, which hold the bolt against the inner wall of the recess, but'permit it to slide eudwise. At its inner end the bolt is provided with a guide-spindle f, which enters a guide-socket g. Aspring h moves the bolt outward toward the bottom of the book, while the bolt may be moved inward against the force of the spring by a handle c'. A laterally-projecting tooth j is attached to the bolt, and this is adapted to engage devices on the strip E. The strip Eis provided with a recess on, upon which is secured a slotted plate m. The toothy is adapted to enter the slot and to engage with the plate at the lower end of the slot at the point m2. Preferably the tooth is inclined, so that the act of clos ing the stripsD E by their handle causes the lower end m2 of the slotted plate to bear against the inclined end of the tooth jand cause the bolt to slide in such manner and sufficiently to enable the tooth to enter the slot and permit its locking end j' to enter beyond the plate fm'. strips are locked together. By pushing in the handle t' the strips may be unlocked and swung back, as indicated in Fig. 2. The strips D E carry curved impaling-pins J J', adapted to pass through perforations in the inner edges ofthe sheet-s F. When the cover is thrown open and the strips D E are in the position shown in Fig. 2, the sheets may be placed upon the impaling-pins.

Whenthe book is closed and the strips D and E are brought together, they are locked by the devices hereinbefore described. After that the book may be opened and closed With'- out separating the sheets, as after the locking devices are applied the covers are opened and closed along the lines of the flexible connections d and b. The impaling-pins are preferably of the form shown, the pins J being solid and the pins J hollow. They are of substantially the same length, and the pins J fit into the pins J, as shown in Fig. 3.

I claim as my inventionl. The combination of the strips, D and E, the slotted plate secured to one of the strips, the sliding bolt arranged in a recess in the other strip and having a slotted portion through which guide'screws extend, a guidespindle,a spring for moving the bolt in one direction, a handle for moving it in the opposite direction, and a tooth entering the slotted plate, substantially as described.

2. The combination of the stiff cover members, A, B, the strips, D and E, the flexible back, O, to which the strips are attached, the hinged portions, a, b, between the parts, A, B, and the back C, hollowy curved impalin g-pins on one of the strips, solid curved By this means the two impaling-pins on the other strip fitting into the hollow pins, the slotted plate secured to one of the strips, the sliding plate arranged in a recess in the other strip, and having a slotted portion through which guide-screws extend, a guide-spindle, a spring for moving the plate in one direction, a handle for moving it in the opposite direction, and a tooth entering the slotted plate, substantially as described. io

In testimony whereof I have hereunto suhseriloed my name.

ROBERT J. BUCHANAN.
