' SUPPORTING STAND non GABMENT roar/rs Appueeuea 'aies January s, 192e. serial No. geiser.

rI`his invention relates to supporting stan-ds for garment or dress forms and particularly to that typek of stand in which the body of the form is adjustable to various heights. 5 rlhe present invention relates to adjustable forms of the type known in the trade as automatic forms and in which the supporting pedestal is made of a pair of tubular telescopic vmembers that are slid longitudinally relalo tively to each other and are locked in vadjusted position by means of a pair of wedgeshaped, internal, expanding members, the ac tuation of which to lock and unlock the stand is controlled through a spring actuated' rod i5 by a foot pedal, the tubular members being constructed to perform a shock absorbing or dash pot function.

While garment forms having `,pedestals of vthis type 'are extensively used, the construc- 20 tions heretofore employed for such pedestals and for the locking means are Subj ect to many objections among which may be noted the failure of the locking means to grip and hold securely the parts in adjusted position; the tendency of the locking members to drop away from their proper positions and to fall into the tubular members, thereby necessitating a 'dismantling of the pedestal to recover the locking members and then a reas- ?e sembling of the parts; the failure of the spring rod, which is connected to one of the locking members, to function properly, the spring exhibiting a tendency to bind on said rod and in additio'nlosing its resiliency after a relatively short period of use; the failure of the tubular members to perform properly the shock absorbing or dash pot action which they are intended to Vperform in which case breakage of the parts frequently occurs; the tendens? Oft maar ofthe parts te break Q1' otherwise get out of order under ordinary usage,and""the difficulty of manufacturing andassemblng the parts- As large numbers of these garment forms are used the arment industry and by highly paid skille Y workers, it isf'f the utmost importance that they 'function properly and require but a minimum amount'ofattention .onthe part of the operative. If, for examl ple, the'loelrin'g members become disengaged medi ately While the operative isengaged in fitting o r draping' a garment thereonfand the body lof the form drops, 'the operatives time iswaste'd in readjusting the device', Likewise, iffthe locking membersV fail to release or grip imwhen the foot pedal is operated the operatives time is Wasted. Y v

In view of the above the principal object of the present invention is'to vprovide anew and improved construction for a device kof the character set forth that will be certain and reliable in the functioning of its locking members, in the kperformance of the shock 'absorbing or dash pot action, and inthe operation 'of the spring actuated rod; that vvwill be of simple and sturdy construction, with the parts thereof so Connected and arranged that dislodgnient thereof out of their proper positions can not occur; that will require but a minimumamount of machining operations in the manufacture thereof, and that mayy be assembled quickly and easily by relatively unskilled labor in a minimumtime.

The above and other objectsr 'will appear more fully from the following more Ydetailed description and byreference to theaccoinpanying drawing forming a part hereof and wherein ig. 1 is a central vertical section through a supporting stand constructed in accordance with the principles of my invention; Figs. 2 and 3 are sections von the lines 2 2 and 3-3 of Fig. 1 respectively, and Fig. 4 is a section on the line 4l4ofFig- 2.

Asvshown in the drawings thenumer-al l() indicates the legs of the supporting `base for the pedestal which radiate from'an'd support at a spaced distance (from the floor'a hollow boss 1'1.v Projecting laterally from the members of an adjacent 'pair 'of legs 10 aindpref erablyfo'rmed integrally "with said legsisv -a i pair of stub pins rawheh ffm' bearings 'for a pedal 1 3. The pedal 13 is'form'ed between *its `ends with a pair of ,laterally projecting heir teenage 14e which, ee eieeriyeehwa u1' the drawings, aie adapted to coioper-ate with 'the pins 12 for pi'votall'y supporti-ng the pedal member.' Learned between un. bearings V14. and projecting downwardly 'fi-ein the underiside of the pedal is. 'a nek er' ne 15 ene. when the pdl`iplalced piti 111150117 the I l'OO Vprovide altreadle portion 13b which portion is provided with a plurality of elongated transverse slots 13.' At the edge of each slot the treadle portion is formed with an upwardly projecting' edge 13d. These edges provide in effect a corrugated surface that prevents the operators foot from slipping oft' vthe pedal when it is actuated.

The sides of theslots 13, as clearly shown in F ig. 1, are preferably tapered sc that the Y 1 wards'the block 28 by the pressure of the slots are wider at the bottom thereof than at the top.v This construction is employed to facilitate the casting of the pedal and also to obviate the tendency ,of dirt from thevsole of y the operators foot to collect inthe slotsand clogthe same.

Extending into the bore of the hollow boss 11 is the lower end of-"a tubular member 17. A short distance from the lower end of said member a spring reaction block 18 is located within said member and, inorder to hold saidv block securely locked, in position'` within thetube 17, said block is provided with a peripheral groove intowhich the metal of the tubevis forced as indicated by the reference `character '19., rlhe tube 17 preferably fits within the boss llwith a neat press fit and, in

order to insure against longitudinal movement of said tube to said boss, a set screw 20 is screwed into the metal of the boss and bears at its inner end against the'outer wall ofthe tube in alignment withthe grooves 19.

Confined between the block 18 and a cupshaped member 21-is a coil compression spring 22 which spring encircles the rod 16. The

. cup-shaped member 21 is of a diameter such that it will slide freely within the tube 17 and which is held against movement relatively to the rod 16 by any suitable means such as the nut 23. It will-be noted that. the spring'22 is entirely enclosed and concealed within the tube 17 and the cup-shaped member 21.

At its upper end the tube 17 passes into a second tubular member 24 which is telescopically associated with the tube 17. The upper end of the tube 24 is closed by a block .25 which is press fitted into said tube 24. fThe .l block 25 hassecured therein the lower end of the present invention relates the body 27 is adjusted and locked in positionat a desired distance from the floor. yMovement of the body 27 to and from the floor is effected by .sliding the tube24 longitudinally relatively to the tube 17 The means for locking the two tubes in`adjustedposition comprises an or contacting faces are similarly inclined so that said blocks will co-operate to produce a wedging action when they are moved relatively longitudinally of the tube 24 and towards each other. Both of the blocks are pro vided with 'a central bore through which the rod 16 passes loosely. The lower block is lsupported upon the upper end of the tube 17,

a washer 8O preferably being interposed between the lower face of said block and the top of the tube. f

'The upper block 29 is normallyurged tospring 22 which, as will be readily understood, exerts through the cup-shaped member 21 andvnut 23 a pressure upon the rod 16 which tends to move the same in a downward direction. This downward movementof the rod 16 is communicated to the bloclr 29 by a nut 31 screwed upon the upper endof said rod. 'A washer 32 is preferably interposed .between said nut and the top of the block 29.

or thelike. This compressible block is adapt 'L ed to be forced againstthe upper washer S4,

.and to beheld against movement longitudinally of the rod 16 by'meansof a nut 36, a lock nut 37 being provided to hold the nut 36 in adjustedvposition. ln order to prevent too rapid leakagecf air from the upper end of the tube 24 and about theblocl 25, a cork 38 is fitted snugly within said tube-24 and is forced into the tube until i-tcontact-s with the block 25.

lt is desirable with a device of the character'V described to provide means for lpreventing the telescopic tubes 17 and 24 frombeing disengaged when the body 27 is raised to its upper- Vmost limit. For this purpose the block 28 is l'made of slightly larger diameter than the 'tube 17. rlhe lower end 'of the tube 24 is slightly iiared outwardly to providea small flange 39. A washer 4Q encircles the tube V24 and rests upon the flange 39. Detachably connected to the washer 40 by any suitable means such as thescrews 41 is another washer 42, the inner diameter of which is less than the outer diameter of the v block 28 and such that the washer 4-2 tube 17.

As a further .precaution against subjecting the stand to slioolrs orblows should the dash pot ltail to function to cieca the downward movement 'of the body 27, a butter spring L18 surrounds the lower end of the tube 17 and rests upon the upper tace of the boss 11, a Washer le preferably being placed upon the upper end of said spring 4:3.'

The operation of the dei/ice is follows: The parts rare shown in F 1 of the drawing in their locled position the spring 22 preme` ing at its upper end upon the bloclr 18 which it will be remembered is held against movement within the tube 17- The lower end of the spring 22 pressing against the cup-shaped member 21 and nut 23 forces the rod 15 downwardly. lt will be understood thaL the rod 16 slides treely through the central aperture of the block 18, rlhe force exerted downwardly by the spring` 22 is communicated through rod 16, nut 81 and washer 82 to the upper bloerQf), thus holding the lower Ainclined face of the bloclr29 pressed tightly against theupper inclined'face ot the block 28. It will be noted thit the cent-ral bores of the bloclrs 28, 29ers considerably larger than the diameter of the rod so t i lateral movement of said blocks is permitted. As the lower blocl is held a inst movement by the tube 1'? the torce ted by the spring 22 acting on the inclined meeting` faces of the blocks 28, will cause said blocks to be moved laterally and to be pressed into tight engagement the inner bore of the tube 24C. [is the diameter of the outer cylindrical surface oi" the blocks 28, 29 is but slightly less than the diameter of the bore of the tube 24 the blocks will grip said tube with a large contacting" surface area and will securely hold the tube 241 against longitudinal movement and in fixed relationship to the tube 17. lr" the operator wishes to change the adjustment of the body 27, the foot pedal 13 is depressed by placing` the toot upon the treadle portion 13" thereof. This will causD the pedal 13 to be rotated upon its learings 12, 14, thus moving the inner end 13a of the pedal upwardly and causing the rod 16 to be moved upwardly against the pressure of the spring 22. As the rod 18 moves upwardly the pressure of the spring 22 is taken up by the inner end of the foot pedal and therefore the pressure is released upon the blocks 28, 29. This will permit the blocks 28, 29 to move inwardly transversely ot the tube 24 and release their friction al holdingA engagement with said tube. The tube 24 and body 2T can therefore be slid longitudinally or vertically to bring the body 27 the desired distance from lie floor. l'ilhen the blocks 28, 29 are releasec as above will slide Jfreely upon the described and the weight of the body-2T and the part-s connected thereto yis not Vsupported by the operator, it is ob, 7tous that theffo-rce oit-gravity will causethe upperine'mbers to descendj In such descent air will betrapped between the leather washer '33 and theupper `end 'oit' the tube'lli which'is closed ,by the cork 38 and block 25. r`The pressure ofthe air trapped between the washer 88 and cork 38 is" sometimes considerable*y particularly if the upper portion is allowed :todrop quickly. The cushioning etlect'howeverV withthe con l struction herein. disclosed is certainiand reliable, thelcorlr 88 preventingfa rapidescapfe ot the air.V l"lhe cork 38 is however'not'entirely ai-r tight andwill permit avery slow escape of the air when the pressure Y ther-eel. v-

mounts:y considerably. The :result is that the upper part of the device will slowly descend to itslowermost limit of travel. i

The provision olf-the coinpressible. block enables the leather washer 3S=to ybe adjusted so as to secure just the proper func tioning of said leather washer. 5

It will be noted that thel in'nfer diameter of the spring 22 is considerably'larger than the outer diameter ofthe' rod 16,t-hereby not only avoiding any binding of ther spring upon said rod but also permitting; said spring to be so constructed'that ity will be vsturdy' and strong in its action and capable; offwithstanding long periods oi.y use. n

The bores of the blocksv 28-are preferably made tapered, as shown in` the lraivings,so that saidblocks may be castfwitliout resortfing to the use of cores in the casting operation, thus materially manufacture, i i i I lt will'also be noted thatthe.washerl 42 will co-'operatewith the bloclr'28 to act as a stop for limiting the upward movement o-f the parts. As it is however sometimes desirable .to dismantle the telescoping tubes, the washer L12 is detachably secured tothe vreducing'V theeostot lower end ot" the tube 2d bythe screws 11. It
