' The hinged connection between the` elements is efectedby proyiding'one ofthe arm and crank elements with pintle .portion'san'd by. providing the other ofsaid elements' with helicalportions which surround the pintle portions?

'Assuming a position ofthe parts where the axis of each pintle portion is'coincident with' the axis of the bearing, the misalignment is such that the two axes intersect each other to form an angle.

4 pintle portions may be bent when the jaws are in an angular position other than 110.

. foregoing angular measurements are given merecrank I4 may be provided with roller bearing 23 which is preferably made of. a strip olf brass.stock`-l which is'bent into more or less cylindri'calg.shape-'-.4 as shown in Fig. 2. The bearing 23 serveswto re-f duce frictional wear on the crankUI4, but it .may

be eliminated insofar as the present invention'i's 1y by Way of example and as an illustration of the manner in which the maximum stressing action can be obtained. Entirely apart from the fore-V going considerations, practically any angular position of the jaws can be'selectedlas the neutral position.just as `long asthe clearance is sufliciently small as to permit a certain amount of stressing as the jaws are moved into their closed Position.

As indicated above, when `the bent axesof theV two pintle portions and of the two helices are aligned with eac-h other, the parts Hare, `in Whatmight be called in .neutral position.

The. parts are bent in such a manner that this .neutralV position occurs when the jaws are in an :f

open position, preferably about 909 to 135V apart.

lfthere is. no clearance between the pintle portions andthe helices, any movement rof the jaws toward each other from neutral position will Inthe manufacture of the particular grment hanger'shown, the helices I9 are formed by:j wrapv ping the rod I Ia, around the pintle portions-24 of rod IDa.

The. aforementioned clearancepermits a certain amount of free movement of therparts before the hinge portions become stressed. For instance, in the embodiment shown, the clearance permits afree movement of about i0"Y on either side of; the-neutral position. Y v

Figs. 3v and l show'the parts in neutral position, the axis of each pintle portion coinciding with the .axis of itsv corresponding helix. Here, .the jaws are 110? apart, indicatedby the upper 'dotted line position of the crank I4 2. j The neutral positionselected is preferably that 4which willproduce the maximum stressing ofthe parts when'in closed jaw position.

that the heuesfaiid the aforementioned patent.

Avportions haveboth' been deformed, with the result that the axes of the pintle portions are more nearly in alignment with each other.

Asshown in Fig. 'Lthe `pintle. portions I9.- need not 'necessary be straight partions. `rDile tothe .nature vof thelbending or drawing operations employed :in the manufacture of the device. .it Iis often difficult to get absolutely straight pintle portions. When the pintle portions` are curvedrthe effectiveai'ris could be considered as being 0incidentwan the 'axis of the hences when th'. parts ,are in that neutral position whichprovidesv the greatest amountof clearance. Y Y' lIt is not necessaryY that lboth helical portions be formed on one rod-fand both pintle portions on the other. For instance, in the. modification shown in Fig. 8, the rod Illa is formed- -withone pintle portionV 24a andV opey helical portion 19h, whereas the rod IIa. is v,formed with one helical portion I9a.- and one pintle portionLZiI-b.. Y Furthermore, it is lobvious, that othertrpes of hinged connection maybe provided,- for the laws I0 and YI l..A just as. lons as the copstruptionjis `such that Vthe two spaced hinged portions may be bent .out of alignment with one another.`4

VIn operatio1i, the hinge portions tend to hold the. jaws apart when the clamping levenli) is ,in the position shown in Fig. 1. When the clamping lever-is swung upwardly into engagement with the roller bearingv 23, afterv the jaws-,have been manually closed, continued mOi/Tementof the clamping lever will draw thecranlr', portions I4 andY I'I togetherland will serveto lock the jaws in-clamped. position.

The rods IaV and I Iamay rbe formed from any suitablewire stock, such as a afnd inch spring wire stock. .'li'orlexample',`v No. Sbright basic lsteel wire has been foundto bei-satisfactory. "Y As shown in Fig. v1,*the outer end ofthe clamping lever 20 may beformed into Sa hook sothat the garment hanger 'may be conveniently supported from 'a clothes rod. However, other sup# porting means may be provided, and the clamping lever may be utilized solely for clamping purposes.

The principles of. my invention may.` also be applied to agarmenthanger in whichv the hinged-V ly connected jaws or other garment engaging elements are biased toward eachother, or into The Y closed position, where such an arrangement is desired.

Although only a preferred embodiment of my invention has been described and shown herein, it will be obvious that various modifications and changes may be made in the construction shown without departing from the spirit of `my invention as defined bythe appended claims.
