TEMPORARY BINDER.

Specification of Letters Patent.

Patented June 3, 1913.

Application filed October 1, 1912. Serial No. 723,353.

T 0 all whom. it may concern Be it known that I, LA Bun B. COPPAGE, a citizen 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, of which the following is a specification.

This invention relates to new and useful improvements in .temporary binders for loose leaves or sheets. Its objectis to provide a simple, compact, and efficient device for this purpose, and to provide a binding mechanism which may be expanded or con tracted without the use of a separate key as has been the custom with devices heretofore used. I accomplish this by means of a lifting device for the locking pawls which is operated by a crank or arm giving great leverage and which is disposed in a con venient position. By this means it is unnecessary to release the tension of the binder in any Way before operating the device. I also provide means for securely locking the device against its use by unauthorized persons. This locking means cooperates with the releasing means above described, thereby providing a secure device when locked as well as a very convenient device for daily use.

Among the features of my present invention are a longitudinal rotatable shaft disposed in the back portion of the cover in parallel relation to the reciprocating side members; simple means for converting the rotary motion of this shaft to a reciprocating motion and imparting the same to the movable side'members, said means consist.- ing of racks and pinions; a locking device for said shaft of a very simple form which engages the teeth of the pinion on said shaft and which may be released from their looking position by a second shaft disposed in parallel relation to said first-named shaft and compactly arranged in the back member; a simple and efficient locking device for said second shaft; and removable binding strips for said cover members.

Other objects and advantages of my improved temporary binder will become apparent in the following specification when taken in connection with the accompanying drawings and the novel features and combinations thereof Will be set forth in the claims.

In the drawings Figure 1 is a plan View of the back member of the binder showing my improvements disposed therein. Fig. 2 is a longitudinal section of one end portion of said back member taken along the line 2, 2 of Fig. 1. Fig. 3 is a cross section of the same taken along the

line

3, 3 of Fig. 1. Fig. at is a cross section taken along the line 4. l of Fig. 1. Fig. 5 is a cross section taken along the

line

5, 5 of Fig. 1. Fig. 6 is an end view of the back. Fig. 7 is a de tail of the releasing yoke.

Referring more particularly to Figs. 1 and 3 of the drawings, it will be seen that the back member of the binder is composed of

removable cover pieces

10 and 11 which are attached to the

reciprocating metal plates

15 and 16 preferably of angular form, the inner flanges or

body portions

15 and 15 having their inner edges adjacent or in contact when the members are in their closed posit-ions. To these reciprocating members I attach the racks 22 and 23 which are 0ppositely disposed With relation to pinions 21. The pinions 21 mesh with and drive these racks, said pinions being integral with or carried by the shaft 21 which extends longitudinally of the binder. I also provide a back cover element 12 which is secured to a metallic plate 17 extending longitudinally of the binder. The said plate is provided with upwardly turned end plates 18 having flanged or grooved upper edges it? which serve as guides for the side memers.

The side cover members are provided with prO ecting tongues or

bars

19 and 20 which work in the above described guides and which insure accurate parallel movements of said side members relatively to each other. The shaft 21 is provided with bearings 23 which are secured to the back plate 17 by screws or other suitable means. The end of the shaft is provided with a square end to receive a removable operating crank 25. By means of this crank the operator may rotate the shaft and thereby cause reciprocating movements in either direction of the

side cover members

10 and 11.

The racks 22 may be secured to the side member plates by suitable screws 27 which are threaded 'ito the flanged ends 27 of said racks. The racks which lie below the pinion may be secured to the opposite side cover plates 15 by screws 23 or other suitablemeans. One of the upper racks 22 is provided with a groove 22 in which slides the end of a screw 22 said screw serving as a stop to prevent the over-travel of said racks and thereby prevent the accidental complete separation of the side cover members. A helical spring 28 is disposed around the shaft 21' being attached to said shaft at one end and to one of the bearings 23 at the other end. This spring is given a tension such as will have the constant tend.- ency to cause a separating movement of the side cover members.

At the middle' portion of the length'of the shaft 1 provide a pinion 60 which is engaged by a series of

pawls

29, 30 and 31 of slightly difierent lengths. These pawls are pivotally supported upon a pin 32 mounted in a frame 33 secured to the back cover member. These pawls are held in engagement with said pinion 00 by springs 34. The varying lengths of said pawls cause a more accurate locking of the shaft and reduce the lost motion.

1 provide a releasing shaft 35 for these pawls,-this shaft being given a position parallel to the shaft 21 and mounted in the bearings supported by the back frame. This shaft is provided with a yoke 36 which lies beneath the

pawls

29, 30 and 31 and is adapted to raise said pawls out of engagement with the pinion 60 when said shaft is rotated. The outer end of this shaft is provided with the small end crank 37 by which the operator may rotate it and thereby cause disengagement of the pawls and pinion 60. A helical spring 38 is disposed around the shaft 35 having one end fixed to said shaft and the other to the frame. This shaft is given a tension such as will cause the yoke 36 to be held out of engagement with the pawls. The shaft 35 is provided with a notch 39 into which a locking member 40 enters, said locking member being integral with a block or bolt 41 which may be operated by a key 42 inserted in the aperture 43 in the end of the back member. The bolt 41 is provided with a notch 44 so shaped that the key 42 will first lift said bolt and then move it toward the left, as viewed in Fig. 5. In lifting the bolt the notch 48 in one end thereof is lifted upwardly and out of engagement with the lug 46 and the movement to the left causes the notch 47 to come into engagement with said lug. The said lug will therefore lock the bolt 41 in either extremity of its movement. A spring normally holds the block 41 in its proper position. The reverse. motion of the bolt 41 is very similar to that above described. The casing 49 incloses said locking bolt and a portion of the shaft 35 and may be secured to the back cover element. A notch 50 in said casing permits easy removal thereof from the shaft 35. The usual telescoping posts and

sleeves

51 and 52 are attached to the side cover members and provided for holding the loose sheets. The said telescoping posts and sleeves are attached to the

removable plates

53, 54 which are secured to the side

cover plate members

15 and 16 by the

screws

55 and 56. The main body of the

cover elements

13 and 14 are hinged to the

movable members

15 and 16 in the usual manner.

In the use of my improved binder it will be seen that the operator may remove a sheet by first unlocking the shaft 35 by means of a key 42 after which he is free to operate the crank 37 and lift the

pawls

29, 30 and 31. This will cause the shaft 21 to be free to rotate. The spring 28 will cause rotation of said shaft in such a direction as to cause the pinions 21 to drive the racks 22 and 23 outwardly and hence the side cover members will be caused to separate. After a new sheet has been inserted the side cover members may be moved toward each other by the pressure of the operators hands, or said movement may be brought about by the crank 25. When the cover members move toward each other they are retained in their innermost positions by one of the

pawls

29, 30 and 31. The cover or

binding strips

10, 11, 61 may be removed at any time by loosening the

screws

10, 11 61 and new strips may be put in their places. The telescoping posts may also be quickly removed from the metal cover members and others that are spaced differently may be substituted.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form and the proportion of parts and the substitution of equivalents as circumstances may su gest or render expedient without departing from the spirit of my invention.
