SPECIFICATION forming part of Letters Patent No. 575,832, dated January 26, 1897.

Application filed June 27, 1896.

To all whom it III/U/l/ concern:

Be it known that I, RICHARD PEATE, a citizen of the United States, residing at J amestown, in the county of Chautauqua and State of New York, have invented certain new and useful Improvements in Book-Supports, of which the following is a specification.

This invention relates to certain new and useful improvements in book-supports for the shelves of book stacks or cases; and it consists, substantially, in such features of construction, arrangement, and combinations of parts as will hereinafter be more particularly described.

In the stacking of books both in private, and public libraries it is desirable that the rows of books be supported in vertical position and compact manner upon the shelves, and while many forms of book-supports have been heretofore devised for this purpose a 7 great deal of inconvenience is still experienced both in the arrangement and manipulation thereof, particularly when the shelves are constructed of metal and very often when the shelves are of wood. In many formerinstances the support requires to be tightened up against the book-row each time the support is moved up into place, and then wheneveritis desired to remove a book from the row special and difficult manipulation of some part of the support is necessary, and very often the entire support has to be removed from its position on the shelf. Other disadvantages also exist with these former devices and which it is the object of the present invention to overcome.

In the accompanying drawings, Figure l is a transverse sectional view of a book-shelf and showing in elevation the application of one of my improved book-supports adjacent to and supported in a guide along each edge of the shelf. Fig. 2 is a view in perspective of one form of my improved book-support. Fig. 3 is a front elevation representing the manner in which my improved support serves to maintain the books of a row in compact form upon the shelf. Fig. 4- is a view similar to Fig. 2 and representing a modified form or embodiment of my improved booksupport. Fig. 5 is a longitudinal sectional view of Fig. 4, and Fig. 6 is a view looking Serial No. 597,215. (No model.)

at the underside of still another form or embodiment of my invention.

My invention is capable of a great many different embodiments, but for all general purposes I prefer the use of either one of the several forms which I have herein shown and which will hereinafter be specifically described. It is preferable in each and every instanceof use that the guide for the support be continuous or unbroken, and it is also desirable that such guide shall occupy a position within the longitudinal edge of the shelf and offer as little obstruction as possible both to the books as well as to the entrance or insertion of the hand for the purpose of adjusting the movable'support. Inasmuch, therefore, as my present invention comprises a book-support that is movable longitudinally of the shelf, and one also that is automatic in character, I prefer to form the guide therefor substantially in accordance with the invention covered by former Letters Patent, No. 560,851, granted to James IV. Hine on the 26th day of May, 1896. Thus, as shown in Fig. 1, A represents an ordinary metallic book-shelf such as is used in connection with metallic book stacks or cases now in use, and along the edges thereof the said shelf is bent around or turned under at l in such manner that the edge 2 is brought in a horizontal plane, and this edge practically constitutes the guide for the sliding or movable'booksupport, as will hereinafter appear.

As explained in the former Letters Patent referred to, each edge of the shelf is constructed as just described,and the support for the books is held upon and between the guides along the two edges of the shelf. Said construction. answers exceedingly Well Where the 0 shelves are of single width only, since then the distance between guides is not so great and the support can very conveniently be made to reach from one to the other guide; but in those instances where the shelves are 5 of double Width to hold two rows of books it would be inexpedient to construct the sliding support of such an increased length, and consequently in the present instance I so construct my improved book-support that butuoo one guide is sufficient therefor, and better provision is also thereby obtained for the support of separate rows of books on double or two-facedshelves. It willbeunderstood,however, that with single shelves also it is not necessary in the present instance to have more than a single guide on the shelf, and in this respect the present invention is a further improvement upon the prior invention referred to, as well as upon all others, so far as I am aware.

Similarly, as in the former Letters Patent, it is the purpose of the present invention to provide a movable bOOk-StlppOYli which, when properly adjusted in position, will become securely held against the books in a manner to prevent them from falling, and in the present case I obtain substantially the same effect and operation of the support either by forming the pendent bearing portion thereof compressible in itself, by which to lock and release the support upon its guide, or else the said pendent bearing portion is rigid or practically incompressible in itself, and the engagement and release of the support are effected in other ways,all as will more fully hereinafterappear.

In virtue of the construction of the guide or rail 1 along the edge of the shelf it becomes necessary to provide means whereby the support can be readily inserted in position and removed, as well as by which said support can be moved to different points of the rail or guide and become instantly engaged or held in such position against the weight of a row of books. Ditferent means could be resorted to; but I prefer that the engagement of the su pport with the guide or rail shall be effected frictionally, and for this reason have devised the several forms which I am about to describe. Thus in each instance the sliding or movable support is designated at B, and in each instance also the support includes an arm 2*, that extends at right angles to the longitudinal guide or rail 1, and which arm lies against the under side of the shelf above the one on which the books are placed.

To provide for the proper support of the books, as, for instance, as shown in Fig. 3, any suitable pendent device could be employed, but preferably in the construction shown in Figs. 1 and 2 I employ a pendent portion 3,

bent at a b c to constitute a plurality of bearing-points for abutting against the end book of a row. To provide for the attachment and adjustment of this form of my device upon the guide 1, I form the inner end of the arm 2 preferably with an enlargement 4E, and bend or turn the same downward at 5, substantially in accordance with the rounded inner surface (3 of said guide, and then in connection with the said arm I provide some form of sliding friction device which cooperates with the arm in effecting a frictional engage ment of the support with the guide. Any suitable sliding device could be employed, as well as any suitable means for effecting the automatic action thereof, but with this particular form of support I prefer to use in conjunction with the arm 2 an auxiliary sliding arm 7, also preferably spread a little or slightly broadened at its inner end, and being also bent or turned down on the edge at 8, similar to the bent or turned-down edge of the said enlarged portion of the arm 2. I form the said auxiliary arm with a longitudinal slot 9 at or near its outer end and a similar slot 10 at a suitable distance from the other end, and 011 the under side of the said arm 2 I provide guiding pins or screws 11 and 12, which pro ject through the said slots 9 and 10, as shown, and normally the two arms are held under tension with the auxiliary arm moved outward to bring the pins or screws 11 and 12 nearly to the inner extremities of the slots 9 and 10, respectively. lVhile thus arranged and operating, the support will be held upon its guide, as shown in Figs. 1 and 3, the bent or turned down edges of the inner ends of the said arms 2 and 7 bearing against the opposite inner curved sides of the rail or guide 1 and the two arms held frictionallyin contact with said guide. \Vith this particular embodiment of my invention I prefer that the necessary spring tension for thus holding the support in posit-ion be derived from the pendent portion 3 of the support, and I therefore construct the same of spring-wire and secure one end thereof to the auxiliary arm 7 at a point beyond the outer extremity of slot 9, and the other end is passed through the slot 10 of said arm 7 and secured in like mannerto the arm 2. The said pendent portion beingbent inward at the points cl to exert a tension lengthwise of the arms 2 and 7, it is obvious that the tendency of these arms is to move past each other, and which tendency, aided by the strength of the portion 3, is what maintains the desired frictional clutch upon the guiderail.

To move the support along the rail, itis simply necessary to grasp the pendent bearing portion 3 and compress the same in the hand, .which action moves the arms toward each other from opposite directions and releases engagement of their inner ends with the rail, and then as soon as properadjustment is made it is simply necessary to let go of the pendent portion,whereupon the support again engages the rail frictionally, as already explained, by the resilient action of the said pendent portion.

As an additional guide for the conjoint 1ongitudinal movement of the arms 2 and 7 I bend or turn down the longitudinal edges of the enlarged inner end of arm 2 at e, and the corresponding edges of the wider part of the arm 7 are received and guided'therebyin the manner shown in Fig. 4-.

Inasmuch as but one guide is employed in the present instance it is possible that the weight of the book-support would in some cases cause the support to hang and not lie up as close against the under side of the shelf as desired, and to guard against this contingeney I preferably form or provide on the longitudinal edges of the enlarged inner end of the arm 2 suitable inclined flanges or wedges 15, which extend transversely to the length of the guide-rail 1 and rest thereon, and when the support is slipped into place upon the rail these inclined flanges or wedges ride upon the edge of the rail 1, and they serve to hold the support in its proper position. Other means could be employed for lifting or elevating the support in close contact with the shelf, but as a simple and convenient means the said inclined flanges or wedges perform the desired function and are preferable for several reasons.

Instead of constructing my improved booksupport as above described I sometimes pre fer that the pendent bearing port-ion shall be rigid in itself, instead of elastic or resilient,

and in that case I construct the said pendent portion substantially of the form indicated at 20, Figs. 4, 5, and 6, and it then becomes necessary to provide for the automatic action of the arms 2 and 7 in some other way. I therefore bend or turn down the outer end of arm 2 as shown at 21, Figs. 4 and 5, and cut a slot 22 in said turned-down portion or lug, and I form the corresponding end of the auxiliary arm '7 with an extension or tongue 23, which passes through the slot 22 and the end of which is turned down at the end in like manner, as shown at 24. A sliding pin 25 is adj ustably secured at 26 to the lug or turneddown portion 21 of arm 2, and this pin moves freely in an opening 27, formed in the lug or turned-down portion 24 of the auxiliary arm 7, and a spring 28 surrounds the pin and exerts its tension between the two lugs, the normal tendency being to spread the said arms apart longitudinally or lengthwise of each other. With this form of the device the pendent portion 20 thereof need have no elasticity, and the two ends thereof are attached through the slot 10 of the auxiliary arm by which to permit the necessary operation.

As a still further embodiment of my invention, reference is made to Fig. 6, wherein the arms 2 and 7 comprise two simple flat pieces of metal, and the construction thereof is in part the same as in Figs. 4 and and in remainder the same as in Figs. 1 and 2. The slot 9 of Fig. 2 is dispensed with, but slot remains, while the turned-down ends of Figs. 4 and 5 are dispensed with and the pendent fingers remain, and the spring and sliding pin are transferred to between the said pendent fingers. Thus in said Fig. 6,35 is the spring, and 36 is the pin.

It will be understood that this last construction operates substantially the same as that shown in Figs. 4 and 5.

Various other changes could be resorted to in the construction and arrangement of the severalparts and still be within the scope of my invention, and therefore without limiting myself in any particular to the details shown and described,
