BOOK-STAND.

To all whom it may concern:

Be it known that I, SAMUEL H. NUcKonLs, a citizen of the United States, residing at Charleston, in the county of Charleston and State of South Carolina, have invented anew and useful Book-Stand, of which the following is a specification.

This invention relates to book-stands such as are particularly adapted for usein combination with school desks, although the stand of the present invention can be used in other connections if desired.

The object of the'present invention is to provide abook-stand which can be easily and quickly adjusted in position upon a desk and which is adapted to bev used in connection with books of various sizes.

A. further object of the invention is to provide adjustable means by which the extreme edges of the pages of the book can be gripped so that the retaining means will not project over or interfere with the sight of.

the print. 7

With the foregoing and other objects in view. which will appear as the description proceeds, theinvention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of the claims without departing from the spirit of the invention;

In the accompanying drawings forming part of this specification :--I* igure 1 is -a front elevation of a. book-stand constructed in accordance with the present invention.'

Fig. 2 is a side elevation showing the stand in position on a school desk. Fig. 3 is a detail view of one of the contact plates on the retaining arms.

Like reference numerals indicate corresponding parts in the different figures of the drawing.

The reference numeral 1 indicates a desk bar which extends transversely across-the top 2 of the desk, and preferably is round in cross section. The desk bar 1 is provided at the ends theredf with clamping members 3 each of which preferably is formed with a pair of curved prongs 4 and an eye member or connecting piece 5 which is formed with an opening to receive the desk bar 1, a ,setscrew 6 being provided in the head or eye portion 5 for the purpose of locking the Specification of Letters Patent.

clamping member in any position to iwhioh;

it has been adjusted upon the desk bar; 1.1 The prongs 4 of the two clamping members preferably project toward each other and-v:

are adaptedto take a firm grip beneath the'a fi fl i edge of the desk as shown in Fig. 1. By. reason of the fact that the desk bar 1 is capable of rotation within the head 5 of the clamping members by merely looseningthe set screw 6, it will be obvious that the bookstand can be swung in a pivotal manner upon the clamp. After the desk stand has been swung to the proper position, the set screw 1 G can be tightened so as tofhold it in such adjusted position if desired; The clamping members 3. however. are not relied upon entirely to hold the desk stand inadjusted 1 position, as a prop member 7 is pivot-ally, connected with the upper bar 8 of the rec-.

tangular frame of the stand, for this purpose. The prop member 7 preferably, although not essentially, is formed of a single piece of wire bent into approximately triangular shape, the free ends of the piece I of wire being wrapped around the upper, cross piece Set the frame, so as to provide a. pivotal connection between the prop mem ber and'the frame proper. The cross piece. I S of the book stand preferably is formed, of.

wire and is bent downward at its opposite ends as indlcated at 9 to produce an aporoXithe vertically extending members}? being bent or wrapped around the desk bar 1 in the form of an eve as indicated at 10.

If it be intended to secure the book stand with approximate permanency on the desk, that is if it be intended to keep the bookstand at all times in combination with the desk, the eyes 10 may be made loose on the cross bar 1 so as to permit pivotal movement pf the frame on the cross bar without loosenmg the set screws 6, but this is not essential and if desired the eyes 10 maybe tightened sufficiently to prevent relative rotation of the cross bar 1.

For the purpose of receiving the back of the book when in open position, wing plates 11 are connected with the frame; These wing plates preferably are formed of sheet metal provided with suitable flanges at their front, bottom and sides, as indicated at 12, the flanges 12 bein wrapped or curled about the framebars o the book-stand so as to hold the wingplates securely in position.

' inately rectangular frame, the lower end of I ofpivotal movement in a plane parallel with tensions 16 are formed with eyes 17.

ea ch' of the eyes1-7 extends a bolt 18 which- 15.

The inner edges of each of the wing plates 11 preferably although not essentially are convexed as shown. I

Extending transversely across the bookstand about midway between the upper and lower edges thereof is a cross piece 14. The

cross piece 14 is formed with eyes lo'which extend around the side bars 9 of the frame. The opposite ends of the intermediate cross piece 14 are extended beyond the side bars of theframe as indicated at 16 so as to form lateral extensions. The extreme ends of said ex- Through is provided with a nut 19. The bolt 18 serves as a fulcrum member for a spring plate 20 which preferably is'formed of fiat spring metal which is bowed as indicatedin F ig. 2, the inner ends of each of the spring plates'20 being bentinto proximity with the, wing plates 11'. The spring plates 20, which constitute retaining arms, are capable the wing plates 11. Pivotally connected with the'inner end of each of the retaining members 20 is an elongated contact member or plate 21 which normally extends transversely of the' retaining member 20. The

meansfor pivotally connecting the contact plate always to lie in parallelism with the edge of the book, but said handle can also be used for swinging the retaining member 20 upon its pivot. 18 so'as to cause it to accommodate books of different sizes. In order to cause the contact plates to take a firm paper, said plates preferably are provided at the ends thereof with teats 23 formed of rubber or other suitable contact material.

The book-stand of the present invention is capable of use in connection with books of variouskinds and sizes. The contact plates 21 can be adjusted so.as to fit upon the edges of the paper between the printand the edge of. the leaf so 'as notto interfere with the free sight of the print. Moreover said bookstand is strong, simple, durable and inexpensive in construction" as well as thoroughly practical and efiicientin use.

\Vhat is claimed as new is A book-stand having a round desk bar provided with adjustable clamps having double prongs extending in opposite directions, a rectangular frame connected with said desk bar, wing plates connected with said frame and having convex edges, a prop member pivotally connected with said frame,

an intermediate bar connected. with the side bars of said frame and lying in back of said wing plates, the ends of said intermediate bar being extended beyond the side bars of the frame, and provided with eyes, bowed spring retaining arms pivotally connected with said eyes, and bearing against said wing plates, contact plates provided with contact teats, and handle members extending through said retaining arms and pivotally connecting said contact plates therewith.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
