To all whom it may concern:

Be it known that-I; JOHN L. Younc, a citizen of the United States, residing at Col lingswood, in .the' county of Camden and State of New Jersey, have invented certain new and useful Improvements in Book V Rests or Tables, of which thefollowing is a specification. Y My invention relates to improvements in book rests or tables, the object of the invention being to provide'an improved device of this character which may be attached to a chair, a' bed, or any other'article of furniture, which is especially adapted for use as a .support for a-book, or -it'may be utilizedas v a table for supporting various articles."

further ob ect s to provlde an iniproved mountingfor thebook rest or support, so that the latter may be readily adgu'sted -an'y'angle, or adjusted-to. anyrotarry-position.

' ,Her'tofore' 4 considerahlestrength to lock them atpositionsof adjustment. I

provide means which rquil e very slight on ertion to effectually lock the-supportin-the.

desired position.

not adjust the device for themselves With these and other objects .'n v1 4 invention consists in certain novel features of construction and; combinations. and ar-" rangements of parts, asiwill be'm'ore fully ongitudinal section of my improved coupling, andv Figs. 5, and 6', are vlews of dee tails of construction; 1, represents a chair in the under face of which-an angle bracket 2 is secured, that is provided with a set screw 3 to clamp 9. laterally projecting arm-4; in the bracket.larm made angular so as to pizeventany' mist-y movemcntin bracket 2 at devices ofthi's kind required.

.Th.is of, great iim port-an'oe, especially as the; device ma be 30 used largely by invalids, who otherwise could outer end is connected by an elbow 5 with a tubular standard 6, having a flanged upper end 7 In this standard 6, a vertical rod 8 telescopes and is clamped at the desired adjustment by means of a thumb screw 9. The vertical rod 8 isconnected by an elbow 10 with a horizontal rod'll onwhich -my.im'- proved coupling or support is mounted. Re- .ferring particularly to Figs. 2, 3, and-5i, it will be seen that'this coupling is provided with a sleeve 12 to receive rod 11, and a set screw- 13 clamps the sleeve againstrotary movement on the rod, therod being preferably fiattened'on its lower face where it is 'engagedby the set screw 13, as clearly shown in'Fig. 3. A hollow post 14 is made integral with sleeve 12 and its upper circular end 15. l

is provided with a central opening 16, and on its upper face is. corrugated radially as shown-in Fig. 5," i

v 17, represents a turn table which is of the same diameter as the circular end-l5, and is -with a central; opening] 18 to. register with opening 16 for'the'accommodation'of a bolt cnd,,and an adj'ustingnut 21 at its upper end. -A coiled 'spring 22- is positioned between the movement, of the turn ;table when pressure is applied on the supportingshelf 23 as will be hereinafter made clear. a

Turn table 17 is provided with parallel perforated-ears which a pin 25 is secured, and provides rotary mounting for a 'sleeve 26 having 'an integral 'arm 27., A plate 28 it the free end of this arm 27 is secured to the shelf'23, so that ,theshelf is supported on the. turntable. On: one. end of sleeve 26, 'anintegraldisk. 29 is locatedand is provided -with a circular series of openings 30 to re- -.ceive in any of them a spring-pressed in 31 supported in one of the arms 24: an. pro jected through an opening therein. A "coiled spring 32"is secured at one end to the .pin, and at the other end to the car 24, so as position, but will permit the pin to be drawn outward far enough to draw it out of one of theiopenings 30, allowing sleeve 26 to the pin will cause it tospring into one of the to always tend to press the pin into lockingturn to the desired angle, when a release of also corrugated to interlock with the corruz I I gatlons of .end' 15. This table 17 is made v 25 his the purpose oimy improvement to 19, saidbolt havin ahead'20 at itslower 'head 20 and the lower face of end 15,'so as to exert spring pressure on the table 17 and hold; its corrugations interlocked, with the corrugations of the end 15,, yet permit rotary 2' eeaaee openings 30 and secure the support in that position.

i It will be noted that the support can he readily turned in the arc of a circle by simply exerting a slight pressure on the shelf.

which will cause the corrugations of the turn table 17 and end to ride in and out withdrawingpin 31, the shelf 23 may be adjusted to the desired angle, hence neither of these adjustments require any material exertion or strength, and this coupling is therefore especially adapted .for use by invalids and will permit them to adjust the shelf or support at the desired angle without calling for assistance and without any danger of accidental movement.

the general form and arrangement of parts Various slight'changes might be made in described without departing from my invention, and hence I do not. limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly .fall within the spirit and scope of the appended claims.

- Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A device of the character described,

comprising a supporting bracket, a horizontal arm secured to said bracket, a vertical tube secured to said arm, a vertical rod telescoping in said. tube, a horizontal arm se cured to said vertical rod, and a coupling secured on said arm, said. coupling comprising a sleeve to receive the arm, a hollow post on said sleeve having a radially corrugated end, a turn table having a radially corrugated lower face engaging the corrugations on said post, a bolt projected centrally through said turn table and post, a spring on said bolt holding said turn table on the post, perforated ears on said turn table, a shelf pivotally connected to said perforated ears, and means for holding said shelf at various angles relative to the turn table, substantially as described.

2. A device of the character destggibed, comprising a supporting bracket, a zontal arm secured to said bracket, .a vertical tube secured to said arm, a vertical rod telescoping in said tube, a horizontal arm secured to said vertical rod, and a'coupling horisecured on said arm, saidcoupling ,comprising a sleeve to receive the arm, a hollow post on said sleeve having a radially corrugated end, a turn table having a radially corrugated lower face'engaging the corrugations on .said post, a bolt projected centrally through said turn table and post, a spring on saidbolt holding said turn table on the post, perforated ears on said turn table, a journal pin secured in said perforated ear's, a sleeve on said pin, an arm on said sleeve,- a shelf on said arm, and means for locking said sleeve at various rotary adjustments, substantially as described. i i

3. A device of the character described, comprising a supportin bracket, a horizon-' tal armsecured to said bracket, a vertical tube secured'to said arm, a vertical rod tele scoping in said tube, a horizontal arm'secured to said vertical rod, and a' coupling secured on said arm, said coupling comprising a sleeve to receive the arm a hollow poston said sleeve having a. radially; corrugated end, a turn table having a-radially corrugated lower face engaging the corrugations on said post, a .bolt projected .centrally post, perforated ears on said turn table, a

journal 'pin secured-insaid'perforated ears, a sleeve on saidpin, an arm on said sleeve, a shelf on said arm, an'integral disk on said sleeve having a circular series of openings,

and a spring-pressedpin on one of said ears adapted to be projected through any of said openings, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
