This invention relates toimprovements in; limbrest stands','and more particularly to atacle holder so that the" portion ofV the limb being worked on is, disposed directly over a receptacle therein. to catch drippage,

or for holding equipmentand the'like.

A further obj ect of the invention 1s to provide a limb rest stand of the class described which may be adjusted vertically, which may be' swiveled, and which maybe tilted to a desired angle.

A further object of the invention is to provide a limb rest stand which may be manufactured easily and relatively inexpensively, which is extremely convenient in use, which' is strong and durable, and which is welln adapted for the purposes described.

With the above and otherobjects inpview the invention consists of thel improved limb rest stand, and its parts vand combinations as o setV forth in the claims, and allequivalents thereof.

'Figf 7 lis a detail sectional view'the'reof Referring'now more particularly to the; ilrawing it will appear that tlie'numeralg-'T indicates.' an elongated tubular support formed from sheet metal rolled into tubular vform of circular-'cross section. ySaid tubular. support has formed liny its -wall vertically alined and spaced-apart bayonet slots 8 con-l 'nectedby aivertical slot 9, g '4 Telescopically mounted within said sup-.l port 7 is anelongated tubular extension post. 10,',V of circular form in 4cross-section, and adapted to be adjustedvertically through the `open upper end portion of the support 7.- Said post 10 is Vsomewhat longerx 'thanfthev There is-'mounted on the upper portion of the post 10, and -spacedly belowfthe upper' .end/portion thereof, a sleevef11. A ycollarV 12 is interposed between the upperend por-V tion of the, sleeveand theV post l10 and'said sleeve is secured to the collar and to the post byl a pair of opposed set screws 13 threaded through all of'said members and adapted to extend into the hollow post 10 for the purposel hereinafter' tobe explained. Said sleeve' 11V is of a4 length suilicient to overlap the upperv end portion of the support 7 when the post 10 is in its extended position.

VRevolubly mounted 'about an' upper portion of thepost 10 and seatingvonjthe upper edge portions of lthe colla-r 12 and sleeve 11, is

. a swivel block ltwhichis'formed with a pair of opposed openings 15 vtoremovablyreceive the depending angular end-portions 16 of an annular bowl supporting ring 16." Said ring is for the purpose of removablyholdin'gor supporting afbowl or receptacle, as shownin dotted lines -in-Fig. 1 and` indicated bythe -numeral 17.

' PAIE-NTOFFICBif The shank 18 of a yole 19 extends revolubly c into the: upper end portionof thel postlO andthe 'lower end, portion of said shank is formed with an annular groove-or recess 2O into which the Linner end vportions of saidzvset screws 13 project. This arrangement-:pre-.l ventsundesired' vertical withdrawal Vof the yoke shank from said postand causes the yoke"v and shank to move vertically withthe post 10 and sleeve 11 when vertical adjustments are made. However, said shank 18 is free to turn or swivel within the post 10. Also, by reason of a pair of opposed notches or recesses 36 formed in the lower flange 37 of the shank 18, said shank may be turned to bring said notches 36 into alinement with the s et screws 13, and then said shank and yoke may be lifted vertically upwardly and be completely removed or withdrawn from the postr10A and associated parts. Y Y

Straddling the upper opposed end portionsof the arms of the yoke 19 is a curved limb rest 21, of saddle-like formation, and its opposed depending arms 22 areadjustablysecured to the arms of the yoke. Extended through one arm and adjacent yoke portion is a bolt or pivot stud 23 having a cotter pin 24 passedthrough its inner end portion.v The otherlimb rest arm and adjacent yoke portion have` extended therethrough an elongated bolt 25A whose shank portion has threadedI thereon a winged nut 26, and between the nut and, the yoke portion, surrounding the bolt shank, is a confinedcoiled spring 27, and the tension of the spring may be varied by` adjusting they nut 26.` The arrangement described permits the 'limb rest 21 to be tilted with respect to the` yoke, and the ease with whichit may be tilted, or its retention in a tilted position, may be controlled by the'nut 26 and spring 27. Y The' lower end portion of the support 7 has wedged into slots therein, a pair of plate members 28v and 29, disposed at right angles to one another and medially crossing eachY otherand having a mortise joint with each other. The projecting end portions of the plate members. 28 and 29have pivotally or hingedly'secured thereto inner end portions of; supporting legs 30, 31, 32 and 33. Saidlegs are of channel formation with theiropen portions faced downwardly, and secured withfv in the outer end portions of the legs are stems of casters 34. The hingeconnections of the legswith respect to the plate members permits the legs to be folded so as to extend longitudinally of the member 7 when they are not in use. for supporting purposes.

The improved limb rest stand is adapted tobe positioned adjacent a chair in which a patient is seated', or other support for the patient. Toadjustthe standy to the proper height the sleeve 11 is grasped and it is turned until: a headed stud 35 projecting laterally from a lower portion of the post 10 is brought into registration with the vertical slot 9 of the tubular support. Then, the post and parts attached thereto maybe raised or loweredewith respect tothe support to the desired height, and the post is retained in the adjusted. position by turning it'and the sleeve tofcausethe stud35 to drop into an adjacent bayonetslot 8. 'The limb rest 21 is then swiveled tothejproper.position. of alinement and tilted to the desired angle and the patients limb is rested thereon and is comfortably supported thereby in a convenient position. The swivel block 15 is turned on the post so as to bring the ring 16 and receptacle carried thereby immediately below the projecting portion of the patients limb.

11i Fso aSii -htly modod form of limb rest is illustrated. In this form the limb rest proper 21 is of table-like formation and is rigidly carried by the upper end portion of the revoluble shank 18.

' vA further modication is illustrated in Figs.l 6 and 7, In this form the swivel block 14 "is rectangular in outline and the post 10 extendsy centrally therethrough, withl ythe block beingtiirnable, on the post. Theblook is formed. with twoopposed. narrow Slots 15 on opposite sides of the post opening, ex-

' tending through the4 block from front to. rear.

Said slots are adapted; tov slidably receive arms 16'. whichare rigidly secured toa bowl Supporting rios 38 the arms. projecting in, spacedireljation laterally vfrom the ring. The upper edges of said arms are formed with series, of spaced notches 39` engageable with upperpins lOwithin thev slots'l.,Y The loweredges of the arms rest on pinsel; within said slots. VIt is therefore. evident that this form of ring isfhorizontally adjustable with respect to the swivelgblock', and is also removable therefrom. j j

Fromltheforegoing description it will be seen that the` improved limb rest stand is of simple and novel construction, and is well. adapted',A for the` purposes set forth.
