TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 507,388, dated October 24, 1893.

A Application filed March 9, 1893. Serial No. 465,287. (No model.)

.To all whom it may concern.-

Be it known that I, CHARLES T. ROSENTHAL, of Batesville, in the county of Independence and State of Arkansas, have invented a new and useful Improvement in Temporary Binders, of which the following is a full, clear, and exact description.

My invention relates to an improvement in the construction of books, and especially to an improvement in the binding of books, and it has for its object to provide a means whereby any number of leaves may be introduced into and bound between the covers of a book, or whereby any number of leaves may be readily removed without injury to the leaves and Without disturbing the leaves adjacent to those to be displaced. I

Another object of the invention is to provide a binding capable of manipulation in the above named manner, which will be simple, durable and economic in its character, and in addition to the cover and devices for holding the leaves between the cover, it is the object of the invention to provide a device which used in conjunction with the said parts will enable the leaves to be expeditiously and readily removed from between the covers.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of a portion of the covers of a book and the binding apparatus to be carried by the covers. Fig. 2 is a partial vertical and. longitudinal section through the covers and the binding apparatus, the section being taken practically on the lines 2-2 in Figs. 1 and 4:. Fig. 3 is a partial vertical and longitudinal section taken essentially on the line 3-3 of Fig. 4:. Fig. 4 is a section taken essentially on the line 44 of Fig. 1, and Figs. 5 and 6 are detail views of modifications in the construction of the binding apparatus. Fig. 7 is a perspective view of a book bound in accordance with my in-.

vention, and illustrates the applicationof the device which is applied to the binding to faconcaved back 0. Within the concaved back,

adjacent to the inner edges of the cover, the binding device constituting the main feature of my invention is located. This binding device comprises two angular strips 10 and 11 of metal, which may be termed body strips, and these angular strips are adapted to extend practically from top to bottom of the concave back section of the cover. The horizontal members of the strips extend transversely across the concave back section, as shown in Fig. 4, and preferably the said members are of such length that a space is created between the horizontal members of the two strips when the strips are placed in position. The vertical members of the strips or plates extend outward from within the concaved section of the cover, and the outer edges of the vertical members of the plates are essentially flush with and are located adjacent to the inner edges of the covers A and B; and what may be termed the outer edges of the vertical members of the plates 10 and 11, are provided with sleeves 12, formed either integral therewith or attached thereto, the sleeves being of diiferent lengths and located at different distances apart.

A draw bar D, is used in connection with the binding plates 10 and 11, and this draw bar is preferably made of substantially U- shape, the body portion being located at the top of the book, while the members of the draw bar are passed through the sleeves 12 of the binding plates or body sections of the binding device, and the members of the bar have free or sliding movement in the said sleeves. The draw bar is preferably made in two pieces connected at the body portion by a sleeve or tube, thus admitting of the bar being increased in Width to accommodate a greater or less number of leaves, and also to receive the device by means of which the leaves are removed or introduced.

The binding or body plates 10 and 11 may be attached to the covers in any suitable or approved manner. Ordinarily, however, at the top, bottom and central portions of the plates tie strips 13, are located, which strips are looselypassed around the members of the draw bar between the two sleeves 12, the sleeves fitting somewhat close to the strips, and the strips after being carried around the members of the bar have one of their ends fastened by rivets or other equivalent fastening devices upon the inner faces of the covers, while the other end is carried through the back portion of the covers and is secured to the outer face thereof, as shown in Fig. 4. The outer attachment may be made an ornamental one, or the outer portions of the tie strips may be so embedded in the covers as not to be visible. The two body or binding plates have their horizontal members connected at top and bottom preferably by hinges 14, in order that the back may be bent at the center, and insuring also a proper return of the binding plates when the back is restored to its normal position either open or closed.

The binding device is completed by the addition of binding straps arranged in pairs and extending transversely across the tie or binding plates, and these binding straps are designated respectively as E and E. One binding strap of each pair is adapted to remain stationary, while the other binding strap is adapted to have movement to and from the stationary one, the movement being given to all the movable straps simultaneously by imparting sliding movement to the draw bar D. The pairs of binding strips are arranged at predetermined intervals apart, one pair, for example, being located near the top of the book cover, another pair near the bottom, and one or more pairs are placed intermediate of the upper and lower ones. The upper binding strap of each pair is securely held between the sleeves 12, the member of the draw bar having sliding movement in the ends of the stationary straps, as the said portions of the straps have eyes formed therein, or are equivalently shaped, while the sliding straps are attached at their ends to the members of the draw bar D, by means of rivets or in any other approved manner; and a sufiicient space is made to intervene the sleeves between which the sliding plates are located, to permit a predetermined movement of the said sliding straps or plates. All of the straps are preferably made in two or more sections of an elastic material, the sections having a sliding connection, and this connection may be effected as shown in Fig. 1 of the drawings, in which the two sections of the strap overlap one another, and the sections are provided with slots 15 and guide pins 16 passing through the slots, while in the event the back of the book is sprung outmal position the moment that such pressure is removed from the covers, by connecting the vertical members of the tie or binding plates 10 and 11, preferably beneath the stationary straps E, through the medium of springs 17.

The binding straps are made of elastic material, in order that when the book is opened the straps will bend upward to allow the leaves to lie flatter than they otherwise would. By reason of the sectional construction of the binding strips, a greater or less quantity of leaves may be bound as occasion may demand. If, however, the book is to be very large, the binding straps may be provided with a number of slots 15 and a corresponding number of guide pins 16 to insure a proper movement of the sections. The binding straps as shown in Fig. 4, are preferably straight, and when the book is made exceedingly large, as shown in Fig. 5, the binding or tie plates 10 and 11 may be made in two or more pivotally connected or hinged sections.

In Fig. 3 I have illustrated the manner in which the draw bar passes through the sleeves 12 of the body or tie plates 10 and 11, and likewise the manner in which the binding straps are held in relation to the draw bar.

Each leaf F to be bound in the cover, as shown in Fig. 2, is provided with recesses 18 in its inner edge, or the edge that is to enter the concaved section of the cover; and the rear wall of each recess 18 at its junction with the side wall is under-cut or counter recessed, as shown at 19 in the said Fig. 2, giving somewhat of a T character to the said recesses 18. The recesses correspond in number and location to the number and location of the bind in g straps, as each recess is adapted to receive a stationary and a sliding binding strap.

In the operation of bindinga set of leaves, the draw bar D is drawn upward or outward, whereupon the sliding binding straps will be carried quite close to the stationary ones, as shown in Fig. 1, and in Fig. 2 this position of the sliding straps is shown in dotted lines. The leaves may now be placedin the back or concave of the book cover, and each recess will receive a pair of binding straps. The leaves are drawn down ward until the stationary binding straps enter the upper extensions 19 of the recesses 18; and when a sufficient quantity of leaves have been placed in the book the draw bar is forced downward, whereupon the shifting or movable binding straps will be carried downward to their lowermost position, and at that time will be forced into the lower extensions of the leaf recesses 18, as shown in positive lines in Fig. 2, and the leaves can not be withdrawn. Any particular leaf, however, may be taken out and another inserted by simply drawing outward the draw bar and carrying upward and drawing outward the leaf to be removed,and inserting in the back and carrying downward the leaf to be introduced; and after a leaf has been withdrawn or has been introduced, as the case may be, the draw bar is carried downward to its normal position. A number of leaves may be introduced at any time or removed at any time, and in order to facilitate the removal of a leaf or leaves, and also to insure at the same time that none of the other leaves shall be disturbed, I have invented what may be termed an expansion device, shown in Figs. 7, 8, 9 and 10. This expanding device, or expander, comprises preferably two body boards 21 and 22, having attached to their lower ends so as to be practically flush with their inner faces, downwardly- extendin g plates 21 and 22, and these plates are provided with transversely aligning recesses 23, the recesses in the plates being so located that when the expander is forced between the leaves of a book the recesses 23 will receive the binding straps of the book. The body boards 21 and 22 of the expander are pivotally connected at one end below their centers ordinarily through the medium of ears 24, placed at these points; and one set of cars is provided with outwardlyextending lips 25, which serve as guides for the introduction of the expanding device into the binding portion of the book, as the said leaves are at that time brought into engagement with either the top or bot-tom edges of the leaves.

At one end of the expansion device a toothed latch bar 26, is pivotally attached preferably at the center; and the spaces between the teeth of the latch are adapted to receive a pin 27, located upon the opposite body board, as shown in Fig. 9. I desire it to be distinctly understood that although the expander is made of wooden body sections2l and 22 and metal lower sections 21 and 22*, if in practice it is found desirable the entire device may be made of metal or other approved material.

In the operation of the expander, after the draw bar D, has been carried outward, bringing the sliding binding straps in position to admit of the withdrawal of the leaves, the book is partially opened,as shown in Fig 7, and supported in that position in any approved manner.. The lower ends of the expander are then brought into engagement with each other, giving to the entire device in cross section a V-shape; and in this manner the lower portion of the expanding device is forced between the leaves and to an engagement with the binding devices of the cover, the binding straps entering the spaces or recesses'23 of the expander, after which, by drawing the upper edges of the body of the expander in direction of each other, the leaves at each side of the inner end of the expander are crowded in opposite directions, and when a sufficient space has been created to receive the number of leaves to be introduced, the latch 26, is brought into action to hold the expander in that position, and the operator at that time is free to insert and fasten the extra leaves in the cover, which is done in the manner heretofore described.

' When anumber of leaves are to be removed,

the expander is carried downward at each side of the leaves to be detached, after such leaves have been bunched, and the expander is then operated in the manner above specified.

It will thus be observed that when a binder constructed as has been described is employed, leaves may not only be expeditiously and conveniently placed within a cover and bound therein, but any one leaf, or any number of leaves may be removed from the binding in an expeditious and convenient manner without in the slightest degree interfering with the leaves that are to remain. Y
