CLARENCE E. CANAN, OF OMAHA, NEBRASKA.

LOOSE-LEAF BINDER.

To all whom it may concern:

Be it known that l, CLARENCE E. CANAN, a citizen of the United States, residing at Omaha, in the cou-nty of Douglas and State of Nebraska, have invented certain new and useful Improvements in Loose-Leaf Binders and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in binders of the detachable or loose leaf type, and among the objects in view, in addition to cheapness and durability of construction, are the facility of manipulation, permitting the ready insertion, and removal of leaves, and the adaptability of the back and sides of the binder to assume a perfectly flat condition when open.

With these and further objects in view as will in part hereinafter become obvious and in partbe set forth, the invention comprises certain novel constructions, combinations and arrangements of parts as will be hereinafter specified and claimed.

Serial No. 499,190. Y

The embodiment of the invention as illustrated in the accompanying drawings comprehends two essential features of construction, one being the back portion and the other the side covers. Of these, the back portion is made up of a fiat, preferably metallic back plate 1, and

side plates

2, 2, hinged to the back plate along the longitudinal edges thereof, as at 3, 3, in position for folding from the condition seen in Fig. 3 to the condition seen in Fig. 4. Each plate 2 is formed at one end with an inwardly turned flange 4, and at the other end with a similar flange 5, the

flanges

4, 4, and 5, 5, being disposed for having their inner edges lie contiguous to each other when the side plates of the back portion are in the folded condition as indicated in Figs. 4, 7 and 9. Plate 1 is provided at one end with an upstanding flange 6, and at the other end with a similar flange 7, leach forming a cross plate.

Flange G is formed with an aperture through which loosely extends a plunger or rod 7, said plunger being free to reciprocate through said aperture and being provided at its outer end with an operating push button 8, and at its inner end with a lock plate 9. A spring 10, preferably of the coiled type, surrounds plunger 7 and at its outer end presses button 8, at its inner end pressing the outer face of plate 6, so that plate 9 is normally held with its outer face against the inner face of flange 6. Near the ends of the plate 9, the same is provided with detent latches 11, beveled inwardly and mov ably extending through suitable apertures in flange 6 in position for

engaging apertures

12, 12, in flanges 4. The inner edge of each flange 4 is formed with a semi-annular recess 13 adapted, when the parts are in their closed position, to surround and accommodate plunger 7 and spring 10. The beveled outer ends of detent latches 11 allow the flanges 4 to move to the closed position, the detents being pressed backwardly until apertures 12 arrive in a position registering with said latches, whereupon the latches spring outwardly into the apertures 12, and

lock the parts in the folded or closed position, the spring action of the detent latches being due of course to the action of the spring 10. It is to be observed that the parts will remain in the folded condition until released, which may be accomplished by simply pressing on button 8, which retracts both of the latches, if the pressure is direct, and the side plates of the back portion will then be free to hinge outwardly to the flat or unfolded condition. Pressure on one side of button S may be caused to retract one of the detents 11 without reti-acting the other, so that one side plate 2 may be released withoutreleasing the other side plate.

Flanges 5, when the plates 2 are in the closed position, lap flange 7 in the same manner as flanges #t lap flange G, and the vertical edges of both flanges and T are preferably arranged to have the inner faces of plates 2 contact therewith and be held against inward collapse thereby, the detent latches 11 serving to preventoutward opening of the side plates 2 during use of the binder.

lVhen it is desired to provide a permanent lock adapted to prevent unauthorized alteration or removal of papers, a suitable lock may be applied to the fianges 5, and the lock may assume any of various forms, a conventional form beine' indicated in the drawing, and consisting of a hasp 1G hinged to one flange 5, and adapted to engage a staple 17 carried by the other fiange 5, the staple being designed to be in turn engaged by a padlock or other suitable locking device 18. Obviously, the lock 18 must be removed and hasp 1G disconnected from staple 17 before the side plates 2 of the back portion may be opened or unfolded, and then all parts are in condition for being controlled by the button 8 and connected parts as above specified.

One of the hinges 3 is provided with a third leaf, as indicated at let, which is free to swing vertically upon the pintle of the hinge, and carries

pins

15, 15, distributed at various points along its length, there being as many pins 15 as may be desired for efficiently retaining the leaves in the binder. Each pin 15 extends upwardly and is curved into a semi-arch which meets the coperating curved portion of a complemental pin 15', there being one pin 15 for each pin 15. Each pin 15 is preferably formed at its free end with a tapered point 15 adapted to enter a suitable recess in the free end of pin 15. The lower end of each pin 15 is rigidly fixed in any suitable manner to the back plate 1. Thus it is to be noted that by swinging the leaf 14I upon its pintle all of the pins 15 may be swung to and from the open position indicated in dotted lines in Fig. 8 simultaneously, and to facilitate such operation a pin 23 extends from each end of leaf 14, near the free edge thereof, through a slot 24 in the

respective plate

6 or 7, the respective flange et or 5 extending above and with its lower edge resting against pin 23 when side plates 2 are closed so as to lock the pins 23 and leaf 14 against movement, so that pins 15 may not be moved from a closed position until side plates 2 are swung open. The outer end of each pin 28 may be pro vided with 2G an operating handle or diskshaped knob for facilitating manipulation, and in order at times to lock the pins 15 in their outer or open position, a detent latch E27 is provided and consists simply of a link pivoted at its lower end, as at 28, and bifurcated at its upper end in position for receiving the respective pin 23, when said pin is in its uppermost position, and for sustaining the same in such position. To release the latch 27, it is only necessary to move the same pivotally out of engagement with the respective pin 23, and to thus lower the pin and allow the latch to rest loosely upon the same, as indicated in Figs. 10 and 12. Of course, if desired, when the parts are in the released condition, the latches 27 may be positioned beneath the pins 23, as indicated in Fig. t. Obviously, while I prefer to use two latches 27, one for each pin 23, so as to evenly sustain the pressure, it is possible to eliminate one of these latches and allow the other to do the work of sustaining the leaf 14 in its raised position. In order normally to retain the leaf 14C in its lowered position with the pins 15 in their closed position, the said leaf is engaged at each end by a flat spring plate 9.8 riveted or otherwise rigidly connected with the back plate 1, as indicated at 29, 29. The spring plates 29 press downwardly upon the outer free edge of the leaf 1li, and the said leaf may be swung upwardly only against the pressure of said springs, so that when the latches 27 are released, after the pins 15 have been positioned in their open condition, the said pins will spring quickly to the closed position under the pressure of springs 28. Obviously, the arrangement, enabling either a momentary or a prolonged retention of the pins 15 in the open position, will allow a very ready removal and replacement of sheets, and the opening of the pins on the central lin-e freely facilitates the insertion and extracting' of loose leaves at any desired point in the body of leaves contained by the binder, the retaining springs insuring the firm retention of the pins in the closed position against accidental opening.

To the back portion are secured the side covers 19, 19, which may be of board or metal as preferred. The edges of each side 19 are inclosed and surrounded by a continuous rim 20, preferably of metal, and the rim Q0 along the inner edge of the side 19 is connected to plate Q by a piano hinge 21 similar in construction to hinges 3, and arranged to allow the respective side to swing freely with respect to the given plate 2 to which it is attached.

In practice, I have found that by reason of the parallel position of the upright or vertical portions of

pins

15 and 15 with the side plates of the back portion when closed, unless provision is made to prevent binding,

' movement of the side plates.

some annoyance is liable to be experienced by reason of a binding action of the leaves occurring between the respective side plates 2 and the contiguous upright portions of the respective pins l5 and 15. To avoid this binding action, 1 have provided

shield plates

30, 30, one connected to each side plate 2 by being fixed to a third leaf 31 hinged to the pintle of the respective hinge 2l. Each plate 30 is provided with a slot 32 for each pin l5 or 15 and thus the respective plate 30 is free to move up and down along the pins with the hinging movement of the respective side plate 2 so that said plates 30 may move from the practically horizontal position indicated in Figs. l, 8 and 8 to the inclined position indicated in Figs. 1, 5, 7 and 9. Thus when the side plates 2 are being brought from their unfolded to their folded position, the guard shields 30 lying beneath the leaves will lift the same and force the leaves along the

pins

15 and 15 to a position on the curved portions of the pins, so that no binding action will occur during the hinging The guard plates 30 will also insure maintaining the leaves confined to the curved portions of the pins while the side plates are retained closed, so that liability of one or more leaves being forced farther back into the file than the greater portion of the leaves is obviated. At the same time, when the side plates are be ing swung to the open position, the guard plates 30 move downwardly and allow the leaves to follow readily and naturally to the open position.

A cover 22 of leather or other suitable material may be secured to sides 19 and extends beneath and covers the entire back portion so as tO add to the finished effect of the binder, and also to serve as a muffler for obviating noise when the binder is being opened or closed or being shifted from place to place. Obviously, the outer faces of the sides 19 may be finished in any desired manner for artistic effect or utility as preferred. For convenience, in applying a metal, leather or other suitable label, the back plate l is provided with apertures 22', 22 adapted to receive the fastening means for the label.

From the foregoing it is believed that the operation of the structure will be obvious, and it is to be noted that one of the essential features of advantage of the invention resides in the capacity of the side plates 2 of the back portion to be lowered to a position perfectly flat and flush with plate l, so that the leaves or other sheets in the binder. when open, lie perfectly fiat at all points, and no raised portion or projection is presented along the inner edge, as is true of many of the common types of binders.
