R. A. STONE LID AND TRAY SUPPORTING HINGE Filed March 17, 1944 2 .remets-sh'eetv 2 Patented Apr. 13,' 194'8 i analisi A Lin TRAYsUPPoR'riNG HINGEv Roy A..`Stone,.Rockford, Ill.,` assgnor to National. i LockfCo., Rockfordgrlll., acorporation of Deia- A Appneatlipnoiuar'ch 1 7, isfigseiiai 111.1526375 order to conserve space, as near a wall as possib1e,`

but if the lid be hing'ed'at its lower edge to the wall of the `chest it will, when open, projefctrear` wardly of the chest a 'distance equal tothe depth ofthe vertical `walls of the lid. This necessitates placing the chestay distance from the wall equal to the depth of the lid wall in order to enable the lid tobe`opened. l O'ne o f the purposes of my present'invention is to provide a hingefor a chest o r cabinet of the character indicated which will materially reduce the projection of the lid beyond the chest rear wallduring thejopening and closing movements, thus enabling the chestto'be set quite close to the w'all. In practice the edgeof a lidmounted by my :improved hinge does not project during its opening and closing movements a distance greater than the thickness Vofthe standard quarterrou'nd usually employed as a, shoe strip along the lower edge offthe baseboard,"'consequently the chestmay be set as nearl he ,wall as the quarter"- round wouldnormally permit. f 1

Another purpose of my invention 'isto rpro` vide y a hingestructure which will support atray in proximity to and movable with the lid and maintain suchtray in horizontal position in all opening andclosing movements of the lid.

Still another purpose of`rny invention is fto provide a hinge structure of'the character indicated which will partially support or counterbalance the lid and tray during opening and closing movements of the lid, thereby minimizing the exertion required to move the lid. o Y 4In order to facilitate an understanding of my invention,` I have illustratedY a preferred embodiment thereof on the accompanyingdrawings, referring to which: 1 1 Fig. 1 isa-perspective view of a chest equipped with my improved hinge, the lid being `shown in open position;

Fig. 2 is an enlarged fragmentary view of one of the hinges witl the lid in closed position;

Fig. 3 is a sectional view on the line 3--3 of Fig. 2;

Fig. 4 is a view similar to Fig. 2 but with the lid in open position;

Fig. 5 is a fragmentary view looking toward the left as indicated by the line 5-5 of Fig. 4, and

hingesof the type 4 claims. (c1. 16e-ite) Fig. G` is a View similarto views 2 andrei but showing the lid in partially open position.

Referring to the drawings more in detailgreference character 'I indicates generally la :cedar chest which may Ioel considered illustrativefof a trunk, cabinets or the like with which ymy invention is designedto `be employed. .Such Achest or cabinet comprises, ascuStOmary, a rear wall li, airont wall S and end walls II and I2, lrespectively. The lid which is of the `usual hollow type comprises the top l13, the rear `wall I4, the front wall l5 and the endwalls I6 andII, respectively.

`The `hinge structure by which the lid `is pivotally mounted on thebody of the chest comprises a body plate I8 secured to the inner face of the end wall IZ, for instance.` It shouldbefnoted at this point thatwhile two hinges;one :at each end of thelid, larerequired in each'finstallation, lhaveifor illustrative purposes in all showings except Fig. 1"shown one hinge only and inthe following description only onehinge will be de-Y scribed,` it being understood that the companion hinge is similarly'constructed-g The plate I8 is secured tothe end wall by screws IS and the wall is recessed as indicated at 2l (Fig. 3) toaccommodate acoil tension spring 22 which is connected "at one fend with an ear 23 turnedV outwardlyfrom plate I8, and 'at its other end'with a'boss 24 slidable in a slot 25 formed in theplate. The spring 229 being of the tractile type biases the boss 24 toward the right (Figs. 2, `4 and 6) or toward its extreme `positionshown in Fig. 4 wherein the lid isin fully open position.

A second plate 26, which may be designated as the lid plate, i s secured `by screws or otherwise to the depending end wall I1 of the lid so as to extend downwardly` beyond the lower edge of said lidand beyond the meeting lineof the lid and bodywhenthe lid is c1os`ed,\a`s shown in Fig. 2. A link 2l hasone .endv pivotally` connected at 20 to the rear depending portion'o'f `the plateZI and its other end pivotallyconnected at 3G to the plate I8 intermediate its ends. A second link 28 hasone endpivotally connectedat 2 9 with the forward depending portion of plate -26 and its other pivotally connected at 3| with the extreme forward end of plate I8. A third link 32` has one end pivotally connected at 33 with the link 28 intermediate its ends and its other end pivotally connected at 34 with the sliding boss 24.

A fourth link 35 has one end pivotally connected at 36 with an ear 31 xedly mounted on the inner face of the lid top I3. The opposite end of link 35 is pivotally connected at 38 with
