the purpose of said blocks being to support the lower edges of the leaves of the book when in place and insuring that the leaves will lie perfectly fiat. The construction of the socket c and tenon d admits of the removal and displacement of-the blocks D, as desired, it being understood that blocks of varying thicknesses may be provided to provide for the varying gages used by book-binders between the edges of the leaves and the edgesof the covers.

E represents legs secured to the lower portion of each board A, having secured thereto a non-abrasive knob or ferrule e.

F represents an angular lug secured to the back of each board A, each having a hole f, in which is pivotally secured an angular PI'OjQC. tion 9 on Ushaped brace G, which supports the boards A A, H being lengths of rubber To all whont it may concern:

Be it known that 1, JOHN S. DUDLEY, a citizen of the United States, residing at Marion, in the county of Marionand State of Ohio, have invented certain new and useful Imrovements in Book-Holders, of which the following is a specification.

My invention relates to devices for holding books in a substantially upright position for reading, but preferably for copying therefrom, and is especially adapted to be used in connection with large books-such as ledgers, dockets, registers, &c.-and has for one of its objects the provision of a holder by which the book may be adjusted at any angle within certain limitations.

Another object is the provision of an adjustable marker for indicating the lines on the book, the vertical rod carrying the marker being so constructed that 1t may be secured tubing or other non-abrasive material on the to prevent lateral displacement when the cross-arm G of brace G.

book is not opened evenly. I represents a socket cut into shelf C trans- Another object of the invention is the proversely thereof and J a piece of slotted. sheet metal secured thereover and having its end turned down on the edge of shelf C, as shown at j, and formed with a hook K, on which is adapted to be secured one of the links of chain L, having one end securedto the crossarm G This construction admits of adjusting the angle of the boards A A and the hook thereon, as desired, by the reader or copyist, the book K being caught in the link of chain L necessary for proper adjustment.

M represents a rod secured to the curved portion b of the cross-bars B B and having secured to its upper end a spring-arm N, on which is slidably mounted a line-marker O, which is held in various positions on said rod N by frictional contact therewith or may be secured thereto by means of setscrew I.

In order to (prevent side play of the springarm N, cause by the book on the holder being opened near its front or back, and the consequent uneven pressure exerted on linemarker 0, I provide a cross-piece or button a on the lower end of said spring-rod N, adapted to fit into socket I, said cross-piece or button a holding the rod N in the center of the book, notwithstanding the unevenness of pressure as above stated.

Having thus described my invention, .what I claim is 1. In combination with a book-holder consisting of upright boards and a shelf thereon, a block removably and replaceablysecured vision of removable and replaceable blocks on the book-edge supporter to support the edges of the leaves, so that theywill lie perfectly flat, said blocks being made of different thicknesses, so as to provide for the different book-binders gages.

The details of construction of my invention will be described hereinafter, and illustrated in the accompanying drawings, in which Figure 1 is a front view in elevation of my improved book-holder; Fig. 2, a side view; Fig. 3, a detail view of the means to adjust the support-brace; Fig. 4, a longitudinal sectional view of the middle fragment of the shelf; Fig. 5, a top plan view of said middle fragment, and Fig. 6 a bottom view of one the leaf-edge-sup port blocks.

In the drawings similar reference characters indicate corresponding parts throughout the several views.

A A represent size secured together by two boards of any desired means of cross-bars boards A A being spaced at a distance from one another and the cross-bars B B therebetween curved, as shown at b, to receive the back of the book, the boards A A being adapted to support the covers thereof.

C represents a shelf secured adjacent to the lower edges of boards A A to hold the lower edgesof the covers of the book and having dovetail-sockets c in each end to receive a dovetail-tenon d on the under side of block D,

- ets, said bloc Q 841,237 g I to the shelf at each end thereof and s aced apart from the upright boards so as to cave room for the edge of a book-cover between said boards and block to seat on the shelf,

while the edges of the leaves rest on top of the blocks, substantially as shown and described.

2. In combination with a book-holder consisting of upright boards and a shelf secured thereto having dovetail sockets in its ends, blocks havin dovetail tenons to fit said socks being formed so that when in position they are spaced apart from the upright boards leaving a space between said boards and blocks for the edges of a bookcover to seat on the shelf while the ed es of the leaves rest on the blocks, substantia ly as shown and described. 7

3. In a book-holder, in combination with upright boards, and cross-bars connecting said boards, a s ring-arm secured to said cross-bars, and a lne-marker slidably mounted on said spring-arm, substantially as shown and described.

4. In a book-holder, in combination with upright boards, and cross-bars connecting said boards, a spring-arm secured at one end to said bars, a llne-marker slidably mounted on said spring-arm, and means to hold said spring-arm from lateral displacement, substantially as shown and described.

5. In a book-holder, in combination with upright boards, cross-bars connecting said boards, and a shelf secured to the boards having a socket in the middle thereof, a springarm secured at one end to said cross-bars, and a cross-piece on the free end of said springarm and adapted to fit into said socket in the shelf, substantially as shown and described.

' 6. In a book-holder, in combination with upright boards, a shelf secured to said boards having dovetail sockets in its ends and a socket in its middle, a slotted piece of metal secured over said middle socket and having its end bent to form a hook, blocks haying dovetail tenons to fit the sockets in the ends of the shelf, cross-bars connecting said upright boards having curved portions therebetween, a rod secured to said curved ortions, a spring-arm having one end secure to said rod, a cross-piece at the other end of the arm to fit into the socket in the middle of the shelf, a line-marker slidably mounted on said spring-arm, a U-shaped brace pivotally secured to said boards, and a chain secured to said brace, the links of said chain being adapted to be secured to the hook aforesaid, substantially as shown and, described.

In .testimony whereof I hereto aflix my signature in the presence of two witnesses.

' JOHN S. DUDLEY.
