LID-sUrPoRTER.

lids of sound reproducing machines, and one of the objects .of the invention is to provide an improved device of this character which will be of a unitary structure whereby the parts may be all mounted upon the same base and whereby the device may be readily installed and at the same time insure the proper positioning of the parts with re-' lation to each other.

A further object is to provide animproved device of this character having means where by a. predetermined degree of friction may be provided between the parts for maintaining them under normal conditions in their adj usted positions with respect to each other but which will, under abnormal conditions.

yield to pressure or force to allow the lid to be shifted. v

A further object is to provide improved means whereby the friction between the parts may be varied at will.

To theattainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and ar-' rangement of the several parts hereinafter more fully descr bed and claimed and shown in the accompanying drawings illustrating this invention, and in which;

Figure 1 is a vertical sectional view of a portion of a cabinet having a lid supporter appliedthereto and constructed in accordance with the principles of this invention.

Fig. 2 is an enlarged detail view of oneof the joints of th'e. lid supporter showing the friction creating surface.

Fig. 3 is an enlarged detail sectional view with parts omitted. of one end of the base member;

modification of the form shown Specification of Letters Patent. Patented N 23; Application filed December 20, 1919. Serial No. 346,340. i I i I Fig. 7 is a view similar, to Fig. 1 of an-vv other form of the invention. I Fig. 8 isan enlarged detail view of one of the joints of the lid supporter showing the friction producing means: 1

. Fig. 9 is an end'elevation of'Fig. 8. Referring more particularly to the drawings the numeral 10 designates generally a casing or cabinet provided with a.lid;11'

hinged thereto in the usual manner as at 12.

Secured to the wall 13 ofthecabinet isabase member 14 which may be of any desired size and configuration but is preferably of a bar like construction of considerable lengthhav ing openings 15 therethroughand through which penings suitable fastening devicespass to engage the casingwall and thereby anchor the base. Pivotally connected with the base 1421s at16 is an element 17 andto the end-of which element .17 is: connected a link 18 as at 19. The other end of the link 18 is pivotally connected as at 20 in any suitable manner to the lid '11 so that as the'li d is moved about itshinge or pivot 12 the link 18 willcause a pivotal movement of the ele-j ment 1'? about this pivot-lfi and with respect to the base 14. In order to counterbalance the lid there is provided ajspring v21, one:

base 14 preferably by means of an ear 22 projecting laterally fromthebase and at a end of which is suitably anchored to the distance from the pivot 16., The otherend of the spring21is detachably secured to the element 17 and in order tojvary the tension of the spring its end isjadjustably connected with the element 17 through the nedium'of the openings 23 so that the ends of the and its end inserted in any desiredone of the openings '23.

spring may be detachedfrom theelement 17 In order to produce friction between the f base'114 and the element 17 so as to retain the lid 11 in, its adjusted position friction creating means }are provided. In the form of the invention shown in Figs. 1 to 5 this friction creating nieansembodies a surface or, segment 24 adjacent and encompassing the pivot 16' andfwhichsurface 24is connected with the base member 14. The element 1 7 isprovidedwith an end 25 which projects beyond the pivot andfover the surface 24 and carried by this end 25 1 s a lug or projection 26 form ed in any suita'ble 'manner, preferablv by stamping out a portion of the end .25, and this lugr'26 isadapted to en: ter openings 27 in the surface '24, the spring or elasticity of the end 25 of the element 17 serving as a means for causing the projec tion to enter the opening. The projection 26 and openings 27 are of such a size and configuration with respect to each other that when the projection enters one of the open ings it will, under normal conditions, hold the lid in its adjusted position but, under abnormal conditions or when force or pressure is exerted upon the lid, the projections will move out of one of the openings 27 and into the next opening as the element 17 is swung about its pivot.

In the form of the invention shown in Fig. 6 the projection 26 is omitted as are also the openings 27 and the friction is produced by the contact of the face of the end 25 0f theelement 17 moving over the surface 24.

.In the form of the invention shown in Figs. 7 to 9, the friction creating surface adjacent thepivotal connection between the base 14 and the element 28 is formed by spaced friction disks or surfaces -29-3O which may be constructed of any suitable friction creating material. In this form of the invention the base member 14; is offset as at '31 and the element 28 is pivotally connected thereto by means of a bolt or pin 32 pasing through the portion 31 and'the element 28, the bolt being provided with a head 33 engaging within the recess formed by the ofi'set'portion 31 and which bolt extends for any desired distance beyond the elements 282930. The end of the bolt is provided with threads 34 to receive thenut 35 and also a lock nut 36 if desired. Encompassing the bolt 32 is a spring 37 one end of all of the parts including the friction creat- 7 ing means and the counterbalancing tension means are mounted. upon the same support 111g structure and the entire device may be appl ed or removed as a unit. Hereto-fore 3 considerable-difliculty has been experienced in that the partshave been made separate or detached from each other and each is secured to the wall of the cabinet thereby necessitating guessing at the proper position for theparts with respect to each other. In thepresent invention, it will be noted that the parts will be in the same relative positions with respect to each other no matter in what position they may be placed in the cabinet or the style of the cabinet,

While the preferred form of the invention has b'eenherein shown and described, it is the base, a link pivotally connected atone end with said element, means pivotally connecting the other end'of the link with the lid whereby when the lid is moved the said element and link will be moved about their pivots, means interposed between the said element and base for counterbalancing the lid, and means adjacent the pivot of the base and the said element for creating a friction between these parts.
