Application filed August 2o,1.1925.-s na1n 51,435.

This invention relates to a support for maintaining a movable member at a certain position of adjustment relative .to a sup portingbo dy, and more particularly-to a lid support of the type disclosed in the applica- I tions of Armer P. Luker, Serial No.. 51,455, filed Aug. 20, 1925, and Samuel H. VVismer, Serial No. 51,488, filed AugfQO, 1925.

An object of .the present invention is to provide a lid support of the .type. disclosed in the above-named applications which embodies the advantagesof. theselformer devices and which possesses additional advantages in construction and economy of manufacture. y f

i More particularly, an object of the present invention is to provide a one-hand lid support that includes novel means ,ifor yield: inglyjmaintaining the lid or movable memher :in at least one position-oi adjustment.

A vfurther object is to provide a single member 'for increasing frictional engagement between the movable and stationary :11.: one adjusted osition.

The invention will be readily understood by reference to the accompanying drawings illustrating one embodiment of ,the invention that is particularlyadapted for use in talking machine cabinets; It is to be expressly understood, however, gthat the'strncture of the present invention is adapted for use in other combinations and ,isnot limited to the particular combination illustrated in the drawings, wherein,

F 1 is a side elevation, with parts broken away, illustrating one embodiment of the present invention installed in a talking machine cabinet; I I

Fig. 2 is a sectio nal e-ndview,takenonthe line 22 of Fig. ,1, the cabinet lid being shown in closed position; and i p F 3 is an enlarged detail sectional View taken on the line 33,of 1. Referring to the drawings wherein like reference characters rei er to like; parts throughout the several views, 1, represents a supporting body,.-as for example acabine't of a talking machine, and 2the lid or cover which is movably secured in any suitable manner .to the body :1 as by means of the usual hinges. Attached to the supporting b dy 'to the mem r a any desired point, but preferably to the innersur'face of thebody 1, is an elongated plate 3 whichplate 3 .anchbody 1 for receiving screws? or other suitable retaining members which extend throughiopenings' in .the plate and into thebody 11 The channel bar .;4,-w hieh may be securedto the plate 3 in any suitable manner, :iS preferably provided with a longi-' tudinal slot 4* whichregist'ers with. a similar slot 3 formed in .the plate 3. The lower side 4 10f the channelzba'r l iscutaw'ay at the opposite ends thereof, as at 4, :Fig. 1, for a purpose to be described hereinafter.

SlidablyQmounted between the upper; and lower walls oftjhe channelbar 4,. is a block 8 which maybe rectangular inshape and which is held in place between ithe walls by meansof a pivot member 9 that is provided i on its 'inner e nd With a Washer '9 which is .held in place by the upset end .9" of the pivot ,pin Loosely mounted on the outer end of the ,pinis a link JlO-IwhiCh' is .held in position by meansof thevouteryhead-9 ofthe pivot ,pin and a washer 11 that ;is=interposed between said link and the plate 31 The upper endfof the .link 10 ;is pivotally secured to anglebraclgetm of any suitable form that is attached to .theinner surface of lid Qasby meansofscrews18.7;

Resilient means aregpr'ovided for increas- I mg ,filGt-IODLl. engagement bet-ween the bloclt 8 and the walls of the' channel bar .4, andalso for resiliently maintaining the block 8 in at ,le asttone positionof. adjustment. In the iorm shown, this resilient 'cineans is constitilted a lea f sjp ring 1,4 :of irregular shape hat is curvedupwardly to engageathe under sidjeoi the-block 8 intermediate itsdength at either side of its pointiof: engagement with the. block said spring is curved downwardly ;to provide yieldable surfaces for tricti'onal' engagement with the side of the channel bar l, the opposite ends of the spring being bent upwardly into engagement with the ends of the block 8'to retain the spring in position. Each end of the spring between its point of engagement with the block and its upwardly bent end is therefore of generally arcuate form 14E and pro vides a yieldable catch which cooperates with the end of the lower side wall 4 when it snaps past'the same, to yieldingly maintain the block, and consequently the lid 2, in raised or adjusted position.

the rear end of the lower side wall 4" as is clearly indicated in Fig. 1. Thelid is thus yieldingly maintained in open position. hen it is desired to lower the lid 2, it is only necessary to press the same downwardly by a slight pressure, whereupon spring 14: is

' compressed, and due to the curved surface of the portion 14;" of the spring, said portion is readily forced out of engagement with the end of the slde wall 4, whereupon the block 8 moves to the right as viewed in ,Fig. 1. i

The friction between the block 8, spring 14:, and the side walls of the channel bar 4, may be such as to hold the lid 2 at any point of adjustment of the block 8 throughout the length of the channel bar 4:, so that an extremely light pressure only is required to move the lid in either direction .after the curved portion 14 of the spring-is forced out of engagement with the endof the side wall l yalthough it iseVidentthat various positions of adjustmentfor the lid may be secured by providing suitable depressions, or by cutting suitable openings or interrup- P10118111 the wall of the channel bar 4. It is therefore to be understood that the term interruption as hereinafter employed is generic to the end of the wall, a depression therein, ora suitable opening therein.

The lidor covercanbc opened and closed without noise and without the necessity of performing two operations or employing two hands. By cutting away the opposite ends of the 'wall l" as indicated at 4 the guide members, constituted by the plate 3 and channel bar 4, are interchangeable and v may be used on either the right or the left hand side ofthe cabinet. Thejspringl l is also reversible. I The side walls of the channel bar 4 are shown as parallel oneto the other, but it will be understood that if desired these side walls may slightly converge throughout their entire lengths,.or a portion of the same. Various other changes may be made in the details of construction without departing from the invention as defined in the following claims.

lNhat is claimed is v 1. A. device ofthe class described compris ing, in combination with a supporting body and a member mounted for movement relative to said body, a guide member having side walls one of which is shorter than the other, means slidably mounted between said walls and having frictional engagement therewith, a link secured to said first-named member and said means, and resilient means interposed between the first named means and the short wall for engaging the end of said short wall to yieldingly hold said first named member in adjusted position.

2. A device of the class described compris' ing, in combination with a supporting body and a member mountedfor movement relative to said body, a guide member having up per and lower side walls, one wall being shorter in length than the other wall, a block slidably mounted between said'walls, alink secured to said first-named member and said block, and a leaf spring, having an arcuate portion, interposed'between the block and shorter wall, said larcuate portion being adapted to engage an end of the shorter wall to yieldingly hold said block in adjusted position.

3A device of the class described cont prising a channel member, a block slidably mounted between the walls of said ember, supporting means operatively secured to said block, and a spring, having an arciiate portion, engaging the block and one of said,

resilient means being adapted to engage an end of the last-named wall to yieldingly hold the lid in adjusted position.

6. A one-hand lid support comprising, in combination with a cabinet and a lid therefor, a pair of parallel walls secured to the cabinet, a member slidabl-y mounted between said walls, means including a link operatively secured to said member and said lid, and resilient means between said member'and one of said walls and normally held in com pression therebetween but expansible into an interruption of said wall for yieldingly holding said member in adjusted position.

7. A one-hand lid support comprising, in combination with a cabinet and a lid therefor, a pair of Walls secured to the cabinet, a member slidably mounted between [said walls, means including a link operatively secured to said member and said lid, and a leaf spring between said member and one of said Walls and normally held in compression therebetween but expansible into an interruption of said Wall for yieldingly holding said member in adjusted position;
