BOOK'BINDER.

To all whom it may concern:

Be it known that I, FREDERICK G. KOL- LENBERG, of Owensboro, in the county of Daviess, State of Kentucky, have invented certain new and useful Improvements in Bookbinder-s, of which the following is a specification.

The object of my invention is to produce a book binder of that class known as looseleaf binders, which, being adapted to hold together sheets of pa er, or pamphlets consisting of a number 0 sheets united, may be employed throughout the range of utility proper to loose-leaf binders generally.

In the accompanying drawings, which constitute a part of this application, Figure I is a perspective view of a complete book, embodying my invention, closed and looking at it from the back. Fi 11 is a transverse section on the line IIIT of Fig I. Fig. III is a' front elevation of the inside view of the back of one of my binders, one end thereof beingshown partially in longitudinal section, and the covers of the back being removed.

Referring to the numerals on the drawing, 1 indicates one portion and 2 the other of my binder back, which are provided, respectively, with end- pieces 3 and 4 which contribute to the slidable union of the members referred to. The end-piece 3 is provided with a slot 5, which is of a transverse extent substantially correspondent to the diameter of a key hole 6 in the end-piece 4. The elongation of the slot 5 is designed to permit, within limits determined by the length of the slot, freedom of relative movement between the members 1 and 2 independently of any obstacle which may be presented through the key hole 6.

8 indicates a bar, located on the inside of the members 1 and 2, and longitudinally movable toward and from the key hole 6. This bar is provided upon one side with a rack 9 substantially coextensive with the distance of the longitudinal movement of the bar 8. It is within reach of operative engagement of a dog 10, pivoted, as indicated atll, to the inside of the member 1 and actuated towards engagement with the rack 9 as by a leaf-spring 12.

13 indicates the tail of the dog, against which a screw 14, working in a screw-plate 15 projecting from the member 1, abuts.

' the screw 14 in one direction By turning towards the bar 8, the dog 10 is forced out Specification of Letters Patent. Application filed March 6, 1907, Serial No. 360,827. Renewed October 24, 1908.

of engagement with the rack 9, and upon turning it in the opposite direction, the dog 10 is permitted to yield to the force of the spring 12 and seek engagement with the rack 9. Opposite the end of the screw 14, a key hole 16 is provided, with which registers the fiatted end 17 of the screw 14.

The bar 8 is operatively united, as indicated at 19 and 20, respectively, to one each of the pivot-pins of two sets of double togglelevers 21 and 22. The pivot- pins 23 and 24, which unite the members of the toggle- levers 21 and 22, respectively, at points opposite the ins 19 and 20 respectively, work free of the ar 8 and of the members 1 and 2, but each toggle-lever is operatively united, as in dicated at 25 and 26, respectively, to the parts 2 and 1, respectively.

By reason of the union between the bar 8 and the respective toggle-levers, and the members 1 and 2 of the binder back, the movement of the members 1 and 2, to and from each other, is rendered controllable by the longitudinal movement of the bar 8, communicated through as many sets of togglelevers as are employed. According to my invention, a plurality of at least two sets of toggle-levers must be employed, as illustrated, but the number may be increased beyond two to any extent desired.

Through the cooperation of the dog 10 and the rack 9 upon the bar 8, the screw 14 being retracted to permit free operation of the dog undertension of its spring 12, it is practicable, without provision of additional mechanism, to render the binder, as described, operative. This may be accomplished by squeezing the members 1 and 2, assumed to be provided, respectively, with suitable enga ing jaws, together, so that they may take hoTd and retain whatever of a suitable nature to form a book that is placed between them. As the members 1 and 2 are forced towards each other by lateral pressure, the pivot- pins 25 and 26 of each set of to gle-levers are drawn closer towards each other, while the pivot-pins l9 and 23 and 20 and 24, respectively, are separated more widely. The result is that the bar 8 is driven longitudinally in one direction. Moving in that direction, the rack '9 on the bar 8 passes against the yielding dog 10, which operates to arrest its movement in the opposite direction. If, however, at any time the operator desires to permit the separation of the members 1 and 2, that may be readily accomplished by turning the screw'l4 againstthe tail 13 ofthedog 10 so as to lift it out of engagement withthe teeth of the rack 9.

Instead of depending simply upon lateral pressure against the members 1 and 2"to' press them together, I prefer to employ a screw 27'revolubly fixed to the member 1, as by the aid of a plate 28 upon said member, and a collar 29 fixed to the screw. The threaded end 30 of the screw works in the internally threaded bore of a block 31that is secured to the bar 8. The end of the screw 27 might operativelytproject beyond the endpieces 3 and-4 of the ack pieces 1 and 2, but

I prefer to provide the screw 27 with a fiatted terminal 33 between the plate 28 and the endpiece 3, where as operatively presented for actuation to a key 34 that may be inserted through the key hole 6 and slot 5. By this arrangement, provision is made against accidental or unauthorized turning of the screw 27, andthe screw 14, as well as the screw 27, may be made to be operated by the same key 34. If desired, any ordinary or preferred meansof protection against the use of an improper key may be employed.

It has been specified that the members 1 and 2 are provided, respectively, with jaws for clamping between them loose leaves, or the like, into a book. Such jaws are shown in the several figures of the drawing and are indicated by'the reference numerals 35 and 36, respectively. Each aw is preferably rovided with a clamping-plate 37 extending from one end to the other of the jaw to which it is attached, the inner faces of the two clamping-plates being arallel to each other. Jaws 35 and 36 preferably are provided with members 48 and 47, respectively. The member 47 is adapted to telescope within the member 48 when the members 1 and 2 are in clamping position, as shown in Fig. III. When the members 47 and 48 are separated through movement of the members 1 and 2, apertured sheets of writing material may be placed over member 47 or member 48, and when said members are in the telescoping position, the writing material is held firmly in place. Each of the members 1 and 2, being preferably made of metal, is provided with a bead-like turn or corner 40, which may serve as a finish and at the same time a recess for the accommodation of a hinge pintle 41, by which each cover 42 of the book may be united to the back members, as by hinge straps 43.

While it is believed that the operation of my device will be well understood from inspection of the drawing, in view of the foregoing specification, yet it is pertinent to add that as often as the number of leaves, indicated by the reference numeral 45, is increased or diminished, the tension upon the clamping-plates 37 being relieved for the purpose, it is necessary only in restoring those described, the screw 14 being sufficiently retracted to permit the working of the dog.

It is to be understood that the operation of this device takes place, as described above, only when the screw 27 is omitted from the construction. In many cases, however, it is preferable to employ the screw 27, and when used the clamping-plates are moved toward or from each other by rotation of said screw. It will be seen, moreover, that when a dog is not employed, or has retired from service through the intervention of the screw 14, the action of the screw 27 is sufii cient to retain the clamping-members in their respective positions.
