HENRY C. MILLER, OF MILWAUKEE, WISCONSIN.

LOOSE-LEAF` BINDER.

Specification of Letters Patent.

Application filed J une 5, 1915. Serial No. 32,317.

To all whom z may concern:

Be it known that I, HENRY C. MILLER, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and VState of IITisconsin, have invented new and useful Improvements in Loose-Leaf Binders, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

This invention relates to improvements in loose leaf binders and more particularly to that type in which the leaves are removably locked to the cover and back by hinged prongs.

It is o ne of the objects of the present invention to provide a loose leaf binder in which the prongs are held firmly in locked position and may be easily swung to open position to release the leaves.

A further obj ect of the invention is to provide a loose leaf binder having a simple means for attaching the prongs and connected parts to the cover and back portion of the binder. l

A further object of the invention is to provide a loose leaf binder which is of simple construction, is strong and durable and is well adapted for the purpose described.

With the above and other objects in view the invention relates to the improved loose leaf binder and its parts and combinations as seb forth in the claims and all equivalents thereof.

In the accompanying drawings in which the same reference characters indicate the same parts in all of the views:

Figure l is a top view of a portion of the improved loose leaf binder, the binder bein shown in o en osition Fi .2 is a transverse sectional view thereof taken on line` 2 2 of Fig. 1; Fig. 3 is a similar view taken on line 3-3 of Fig. l; Fig. 4 is a longitudinal sectional detail view taken on line 4 4 of Fig. 1; Fig. 5 is a transverse sectional detail view of a modified form of binder; Fig. 6 is a top view of another modilied form of binder; Fig. 7 is a transverse 4sectional detail view thereof taken on line` on line 11-11 of Fig. 8; Fig. l2 is a longitudinal sectional detail view taken on line 12 -12 of Fig. 8, the prongs being shown as in closed position; and Fig. 13 is assimilar v1ew with the prongs being shown as in open position.

Referring to the drawings the numeral 15 lndicates the cover which comprises the side portions 16 joined together by the back port1on 17. A pair of prong or hook plates 1.8 are positioned adjacent to the back portion and have their inner edges hingedly connected together by angular tie members 19 which are engaged by notched portions 20 of the prong plates. The prong plates are held yieldingly in open or closed position by spring members 21 having hooked end .portions 21 which hook over notched portions 18 of the outer edges of the prong plates. The medial portions of the, spring members are coiledor looped as indicated by the numeral 22 Ato permit the use of longer springs than could otherwise be used and to also provide means for' removably securing the spring members to the cover back.

In constructing the cover back 17 a metal reinforcing plate 23 is interposed between and attached to the thicknesses of the materlal of the cover back and is provided with projecting eyed portions 24 which overlap the plane of the spring loops and a locking bar 25 extends through the loops 22 and the eyed portions 21 and removably locks the parts together. The locking bar may be withdrawn endwise to disengage the parts.

Semicircular shaped prongs 26 are mounted in pairs on the prong plates and their upper free ends overlap each other when in closed position to form a circular leaf holding means for holding removable leaves A. As the inner edges of the prong plates swing above and below the plane of connection of the springs with the outer edges of the plates, the plates will be yicldingly held in their upper or lower position and the prongs mounted thereon in either open or closed position. The angular faces 19 of the tie members 19 serve to limit the upper and lower movement of the plates, and when in their lower position the upper ends of the curved prongs partly overlap and abut against each other. Vhile the prongs 'may be swung to open position by pulling the prongs apart, it has been found more desirable to provide Patented Oct. 10, 1916. j

a push button means for accomplishing the same result. This means comprises abell crank lever 27 which is interposed between the-cover 'back and the prong plates and is pivotally connected to said cover back. The short arm 28 of the lever engages the inner edge portions of the prong plates and the outer vend of the long arm 28 projects outwardly from the cover back and is adapted to be pressed downwardly to swingJ the short arm upwardly and the prong plates to open position.'

In the modified form shown in Fig. 5 the spring 29 is slightly different from the springs '21 in that it extends over the upper portionsl ofthe-prong plates and its loop 30 depends through an opening 31 formed between the said prong plates. .The locking bar 25 extends through the loopin the same manner as before described to lock the plates to the cover back.

In the Figs. 5 and 6 modified forms the outer edge portions of the prong plates are bent to form eyed portions 32 through which extend pintle hinge pins 33. The outer edge portions of the prong plates are notched as indicated' by the numeral 34 to expose the pintle pins and to accommodate the eyed ends'35 of the spring members 21 and form a hinge connection therebetween.

In the modified forms illustrated in Figs. 8 t0 13 inclusive, the use of spring members is eliminated and in lieu thereof a slidable locking member is provided which may be moved to open or close th'e prongs. The slidable member 36 is provided with angularly disposed grooves orrecesses 37 which incline downwardly toward each other at their outer end portions as shown in Fig. 10.

From the outer end portions, in a direction toward the inner end'of thelmember, the inclination of the grooves or recesses gradually change and at the inner end ofthe member the grooves extend upwardly toward each other as shown in Fig. 1 1. The adjacent ends of the pron plates are adapted toenterthe grooves of the locking member when said vmember is pushed inwardly and in entering the grooves the prong plates will be forced downwardly to closed position and locked in said position while the locking member is in closed position.

In order to permit the prong plates to the abutting edges of the prong plates are cut away to form an elongated opening 42 to receive the grooved portion of a slidable wedge member 43 which is adapted to swing the prong plates to open position". The

-.wedge member is linked to a wire loop 44 which forms part of and projects inwardly from the locking member and is moved thereby. The wedge member is positioned with its inclined portion 45 adjacent to the angular face of the bent portion 40 so that as the locking member is pulled outwardly to' unlock the prong plates the wedge member will ride up the angular bump 40 and swing the prong plates to open position. When in open position'the lower Hat portion 44 of the wedge member will rest upon the upper flat portion of the bump and the parts will remain in open position.

For convenience in operating the locking member, it is provided with a flat end plate 36 which may be easily engaged by the linger of the user to open or close the prongs.

From the foregoing description it will be seen that the loose leaf binder is of Very simple construction and is well adapted for the purpose described.
