LOOSE-LEAF BINDER.
Specification of Letters Patent.
Patented Feb. 27, 1906.
To all whom, it may concern:
Be it known that I, EMORY A. TRUssELL, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Loose-Leaf Binders, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.
The lnvention relates to expansible backs or binders, particularly adapted for use in connection with account -books, and more specifically to a three-part binder comprising a pair of side or pressure plates with instanding leaves formin parts of the back, and a third back plate for covering the space between the two outer members and allowing of the telescopic action of the latter relatively to it.
The objects of the invention are to provide simple and efficient means for expanding and contracting the back and which will operate with increasing power in compressing het side plates upon the contents of the holder.
The invention consists in the mechanism hereinafter described and which is illustrated in the accompanying drawings, in which- Figure 1 is a plan view of the interior of the back, some of the parts being broken away. Fig. 2 is a central sectional view on the line 2 2 of Fig. 1. Fig. 3 is an end elevation. Fig. 4 is a sectional view on the line 4 4 of Fig. 1. Figs. 5 and 6 are details of arts of the mechanism, showing modified orms of construction and Fig. 7 is a detail section on the line 7 7 of Fig. 1.
The binder-frame only is shown and is of metal. It will be understood that it is ordinarily covered with leather or other suitable material and provided with side or cover leaves.
The binder-frame comprises the side members or plates 10 11, shown as of cast metal and each having an instanding leaf 12 13, forming a part of the back of the binder, and end plates 14 15, forming parts of the ends of the binder-frame.
An intermediate back-plate 16 has a bearing on and is in telescopic engagement with, the leaves 12 13 and has upturned ends 17 which com lete, with the end plates 14 15, the ends o the binder. The end plates 17 are overturned at their top edges, as shown at 18 to form ways within which the ends 14 15 may slide. The parts are so proportioned that when the binder is contracted to extreme limit the inner edges of the plates 12 13 are approximately in contact. When the binder-frame is expanded to its extreme width, the plates 12 13 are still within the margins of the plates 16.
The binder is controlled by means of oscillating cam-plates 19 20, pivoted at 21 22 to the plate 16 on its longitudinal median line, each of the'cam-plates being provided with cam-slots 23, which are oblique to its radius and are engaged by antifriction-rollers 24, mounted upon pins 25, set in brackets 26, projecting inwardly from the side plates 10 11. Preferably the brackets 26 are bifurcated, as shown, the cam-plates running between the two legs, and thus being stayed, so as to stiffen and strengthen the binder-frame as a whole.
The cam-plates are actuated by a wormshaft 27, j ournaled longitudinally on the plate 16 and carried by bracket-arms 28, rising centrally from the plate 16 and being offset laterally, the worms 29 30 of the shaft engaging worm-gears 31 32, formed on the hubs of the cam-plates 19 20. One end of the wormshaft 27 is recessed, as shown at 33, to accommodate a key, one of the end plates, as 17, being apertured to permit the insertion of the key.
As a further guide for the side members lof the binder a cross-bar 34 may be located at each end of the plate 16, rising from its median line and extending laterally in both directions and being spaced apart a sufficient distance from this plate and its upturned end to provide ways for the leaves 12 13 and end plates 14 15.
The cam-slots of the plates 19 20 may be shaped as desired. The curved camslots 23 (shown in Fig. 1) I find to be the most satisfactory, providing, as they do, for decreasing speed and increasing power as the binder is contracted.
The slots 35 (shown in Fig. 5) are given a sharper curve and provide a substantially IOC uniform speed and power throughout their entire range of movement of the binderframe.
The slots 36 (shown in Fig. 6) are straight and provide for a very rapid movement during the earlier part of the contractive action and a very slow movement and a decided acceleration of power as the limit ofthe closing movement is reached.
The usual telescopic leaf-holding rods are shown at 87 and project inwardly from the side lplates 10 11.
I claim as my invention- 1. An expansible binder-frame comprising a pair of side plates having instanding back leaves; an intermediate back plate in sliding engagement with such leaves; oscillating cam-plates pivoted on the intermediate back plate and having cam-slots oblique to their radii; members carried by the side plates and engaging the cam-slots and means for oscillating the cam-plates.
2. An expansible binder-frame comprising a pair of side plates having instanding back leaves; an intermediate back plate in sliding engagement with such leaves; oscillating cam-plates pivoted on the intermediate back plate and having cam-slots oblique to their radii g members carried by the side plates and engaging the cam-slots; a Worm-shaft journaled on theintermediate back plate g and Worm-gears mounted with the cam-plates and meshing with the Worms of the shaft.
3. An eXpansible binder-frame comprising a pair of side plates having instanding back leaves; an intermediate back plate in sliding engagement with such leaves; oscillating cam-plates pivoted on the intermediate back plate and having curved cam-slots oblique to their radii; members carried by the side plates and engaging the cam-slots and means for oscillating the cam-plates.
4. An expansible binder-frame comprising a pair of side plates having instanding back leaves; an intermediate back plate in sliding engagement with such leaves oscillating cam-plates pivoted on the intermediate back plate and having cam-slots oblique to their radii; bifurcated brackets extending inwardly from the side plates and straddling the cam-plates, and pins set through the brackets and engaging the cam-slots.
5. In a loose-leal binder, in combination, a pair of laterally-movable compression members, and levers for actuating such members and engaging the same by a cam-action and being arranged to act With increasing power as the compression members move toward each other.
