Application filed 2G,

( supporting the r shade in any dosgect to a chair ch the device 16 A further object c f niy inven tion to provide a device of the above character capable of a multiplicity of use V stationary bracket constructed and arranged for connection to an object such as the back of a chair, rocker or bench, said bracket hav-' ing a globular terminal and a sectional block or casting capable of ad ustment to any angular position relative thereto and a lunged clamping arm forretainlng the handle an umbrella or shade.

To enable others skilled inthe art to i'i'iore fully comprehend the underlying features of my invention that the same may be more easily understood, reference is had to the acconn panying drawing showing a preferred embodiment wherein t r Fig. 1 is'a perspective view.

Fig. 2 is an exploded view-ofthe parts and their relative position. for assembly.

Referring now to the drawings wherein like reference characters designate corre spondin g parts throughout they Jews, 5 desighates the bracket body having a flanged stationary jaw 6 at one end, said aw being provided with notches 7 which assist in clamping and gripping an object to whichthedevice is to be attached; The bracket body is also formed with a depending sleeve 8 int-ernally threaded to receive a clamping screw 9. The clamping screw carries a movable jaw 10 its inner end; said jaw being retained by a threaded screw and nut 11 which also permits the jaw to loosely rock or pivot so as to engage any irregular surface or ob ect such as the back of a chair, rocker or other article of furniture to which the device is to be connected. The movable jaw is in the form of a yoke, the vertical arms 12 of which stradi'l e the lower portion of the body 5 and along which it is guided when the clamping screw is rotated. The said movable jaw back of a 9 and coniprsing a p 192?. sci-m1 No. 194,223.

thereforis capable of adjustment between the threaded sleeve and the stationary jaw to support the device under various condi- 121 ns.

the bracket body 5 or ball being seated within a circular recess 19in the opposite section 20 of the said block or casting. A threaded. thumb screw 21 passes through a threaded sleeve 22 and bears against the flat surface 23 of the semi-spherical socket thus clan'iping the block or casting in an adjustable position on the globular end of the bracket.

The section 18 of the block or casting is pro-' vided with top and bottom flanges 24; and 1n-.

wardly extending ears 25. The rear wall 26 is slotted at 27 for the passage of the threaded shank portion 28 of an eye bolt 29, said eye bolt belng held by the vertical screw 30 and nut 3O extending through apertures 31 in the ears 25.

The opposite section 20 of the block or castali gned ing is also formed with top and bottom flanges and inner spaclng lugs 33 which malntaln' the sections in parallelism and afiord sufficient space therebetween for the passage of the straight portion 142 of the bracket; The lugs are cut to provide shoulders 33 for the yoke shaped extension 35 of the semispherical socket which prevent its rotatlon relative to the sections ofthe block and between the lugs 1s a U-shaped slot 36 which permits of the clearance of the eye portion of the eye bolt. The rear walls of each of the sections constituting the block are provided with aligned apertures 37 for threaded screws and nuts 38, 39 which fasten and retain the two sections together, said screws being located so not to interfere with the threaded eye bolt abovereferred to. It will'thus be seen that while the sections are locked together, the block is capable of movement as aunit to'any angular position relative to the ball of the sphere on the end of the bracket and that by tightening the threaded thumb screw the block may be held in its adjusted position in the desired angle.

is preferably integral with an angular extension 13 and a'straight,

The top and bottom El: 20 the block are provr; c

o ateral cars lO which cooperate Withthe ears ll or a hinged clamping plated?? said ears having aligned apertures 43 for the passage of a screw 4 held by a suitable nut. The straight wall portion 45 oi the clamping plate is ,L'Jtted as at at; for the passage of the extended shank portion of the threaded eye bolt which plate is adapted to be clamped by a thumb nut 47 and Washer 48 against the handle of an umbrella or shade ll) it deing further noted that the outer end of the clamping plate is bent inwardly .as at 50 to prevent the sepa ration ot the handle when in its claiipeo sitionu 'l he clan'iping plate is re'en'lorceal outer ribs 51 which prevents its fracture whei. cons'derable pressure is brought bea as when gripping an. object such as a handle.

above referred to. Since the clamping plate is hingedly connected to and supported by the sectional block, it Will be seen that any ad just-merit oi? the block will correspondingly adjust the angularrelation oi: any object held between the end of the block and the cla oing plate. The spherical connecf in which is in the nature oi? a universal joint permits out the widest possible range of adjustm nts after the object is held in its clamped posi ,ion

merely loosening the thun'ib nut and. ineving the block relative to the globular end oi the bracket. I While l. have shown and described. my in vention with some degree of particulari" realise that various changes and aiteratons in the details oi the construction may be resorted to. I therefore reserve the right to make such changes, modilications. and alterations in the details 2' may fairly fall within the scope of the subject matter now being claimed.

1 claim: v
