`Specification of Letters Patent. i @attent-Qd June 27, 1922.

Application iled December l5, 1919. scrialNo. 344,822.

To all whom t may concern.'

Be it known that I, JOHN BYsTnoM, 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 Loose-Leaf Binders, of which the following is a specication.

This invention relates to improvements in loose leaf binders and one of the objects of the invention is to improve and simplify the construction of devices of this character and at the same time provide an improved device which will be strong and durable in construction and effective and eiiicient in operation,

A further object is to provide improved means for securing or connectingthe various parts together.

A further object is to provide an iinproved spring construction by means of which the prong carrying members will cause the prongs or rings to be opened and closed with a springaction, and improved means for seating or placing the spring elements in position.

To' the attainmentV of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantiallythe construction, combination and'arran'gement of the several parts hereinafter more Jfully described and claimed and shown in the accompanying drawing illustrating this invention and in which: I

Figure y11 is adetail reduced perspective view ofthe back plate; Y

Referring more yparticularly to the drawing the numeral '15 designates a base plate of a casing in which the operating parts of the device arelocated. The casing also embodies a top member 16 and these members are secured `together in any suitable manner such as by anging the edges of the base plate over the edges of the top plate and the casing may be of any desired configuration in cross section. f

VWithin 'the casing thus Jformed are twosubstantially fiat members 117 which are orn a length somewhat shorter than the casing.

These members are placed together so that i' A their inner edges 18 will stand in close prorr-` imity and these inner edgesare provided with ears or lips 19 adapted to overlap the other member to hold the edges of the members against separation.y The outeredges or' cachot these members are provided with any desired number ofrrecesses 20 in which recesses resilientlinksy 21 are adapted to be,

seated.V These links 21 are of a length to encompass ythe members 17 and when seated in the co-operating recesses 20 will serve to liold the edges 18 oit the members 17 together `for* pivotal action with respect to each other and also serve that when the members 17 are rocked with respect to each other to impart a springaction tothe meinbers. The links 21a-re shapedso that the ends 22will overlap and when it is desired to'insert orplace any of the rings 21 in position intermediate the ends lof the kmembers 17, this maybe accomplished by turning the ring in such a'position thaty it will lie in substantially the same plane as the plane of the members 17 after which the edge of one of the members 17 is inserted between the overlapping ends 22 of the link and when the link has been passed over the plate, the link may then be twisted at right angles to the member 17 so as toenter recessesrQB as t shown in dotted lines in Figure 6. The

recesses 23 are preferably spaced a short distance from the adjacent'recesses 20 and the edges of the members 17 intermediatev the recesses 20-23 are beveled or inclined as at 24 so that when the link is seated in the recesses 23 it may be forced into the recess 20 by forcing the link over the inclined portions 24 of the members 17 until the link stands over the recesses 20, at which time the resiliency of the link will cause it to snap into and be seated within the recess 20.

The end links 21 are applied in a similar manner; that is to say the ends ofthe members 17 are beveled or tapered as at 25 so that the link may be slipped over the ends of the member 17 and then forced over the inclined faces 25 until they spring into the adjacent recesses 20.

Carried by each of the members 17 are prongs or ring elements 26 which may be of any desired size and configuration. @ne end of each of these elements 26 is provided with a slot or bifurcation 27 to form the walls 2S. These` elements 26 are secured to the respective members 17 preferably in the following manner. The members 17 are provided in their outer edges with recesses 29: opening through the respective edges, one recess being provided for each of the prong or ring elements 26 to be secured thereto. Adjacent these recesses 29, and spaced therefrom and within the confines of the edges of the member are apertures 30 which are in alinement with the respective recesses. 29. To apply the elements 26 the bifurcated portion 27 is passed over the edge of the member 17 so that the element 26 will stand within the recess 29 and will be spaced from the outer edge of the member 17. The extremities of the walls 28 of the slot or bifurcation 27 terminate in alinement with the slot 30 and the extremities of these walls are thenl bent or deflected towards each other so as to extend partially into the aperture 30 to secure the element 26 in position.

t will thus be seen that with the prongs or ring elements 26 secured to the member 17 that the ends of the elements 26 will abut when the parts are in the position shown in Figure 1, but when the members 17 are rocked with respect to each other, the ends of the elements 26 will be separated or will assume the positions shown in Figure 2.

These members 17 are of a width to fit snug-ly within the casing formed by the members 15-16 and inasmuch as the prong or ring element 26 is spaced from the edge of the member 17 and inasmuch as a portion of the element 26 will enter the slot 31 in the top 16 of the casing, it will be manifest that the edge of the bottom member 15 may be flanged over the adjacent edge of the member 16 for securing the parts together and the extremity of the iianged edge will terminate short of the element 26 so as not to interfere with the pivotal .movement of the members 17 or the elements 26.

Any suitable means may be provided for rocking the members 17 with respect to each other but preferably a lever indicated generaliy by the reference numeral 32. This lever is bent so as to form a hook shaped end 33, the extremity 34 of which is preferably inclined and the lever is provided with an operating handle 35. The lever is also provided with laterally projecting arms 36 for holding it in position. This lever 32 is loosely connected with the members 17 through the medium of recesses 37 which open through the inner edges of the members 17 adjacent one end and combine to form a slot into which the end 33 of the,

lever is hooked. Then in position the lever will normally rest upon the bottom member 1.5 and the arms 36 projectinglaterally from the operating lever will engage the wail of the casingto hold the lever in position.

It will thus be seen that assuming the lever to be in the position shown in Figure 9 the elements 26 will be in a locked position with respect to each other, or in a position to hold the leaves in the binder. By depressing the handle 35 the plates 17 will be rocked with respect to each other and the links 21 will impart a spring action to the members 17 so that the co-operating` elements 26 will separate with a spring` action. In order to cause the elements 26 to assumo al locking position with respect to each other the handle 35 of the lever is moved in the opposite direction to move the members 17 about their pivotal edges in the opposite direction, at which time the arms 36 will hold the lever against displacement within the casing and when the members 17 are moved they willA travel backwardly with a spring action.

The bottom member 15 of the casing may be provided with any desired number of slots or openings 38 and a flexible member 39 such as cloth or the like is provided for securing this holder in position between covers, etc. The flexible member 39 is secured to the casing member 15 in any suitable manner and a back plate 40 may also be provided which is placed adj acent the outer face of the iiexible` member 39 where it passes over the member 15. This plate 40 is provided with any suitable number of prongs 41, one for each of the openings 38 so that when the member 40 is placed against the fabric member 39 the prongs l1 will pass through the fabric and enter the respective openings 38 in the casing member 15. after which the extremities of the prongs 41 may be flanged down against the inner Iface of the casing member 15 for holding the member 40 in position.

While the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combinationk and arrangement of the several parts within the' scope of the' claims without departing` from the `spirit of this invention.
