Beitlgknown that I'"WiLLiAM A. ScHiLLEn,
Td dllitbiom' it concern:
Chicago, in the county-of Cook and State of Illinois, have invented certain new and useful Im rovements'in Lid-Supports, of which the fol owing is a specification. c
This invention relates to devices for vsupporting' hinged covers oi.- lids for boxes,-
trunks or Aother articles, and the especial object ofthe improvements which forni the subject matter of this application is to produce anA adjustable device that will ei'ectively rsu port the lid at different angles and that wil automatically lock andunlock itself by merely moving the lid.
General objects of economy of construction and simplicity of o eration are'attaincd by my invention as wil be readily apparent.
. In the accompanying drawing which forms a part of this applicationz-fFigure 1 shows in elevation my invention as applied to a box and its lid; Fig.'2 shows in elevation my device in its lid -sii porting'position; Fig. 3
arts when the braccis unloc ed; Figi/1v is a fragmentary detail showing a different` method of connecting the supporting brace with the lid.
Referring to the details of the drawing, 5 re resents so much of a box as is necessary to 1 lustrate my invention, and 6, the lid which is hinged ci thebox.
7 represents the brace which is formed from a single piece of thin metal cut out in the shape shown, and yprovided with the teeth 9 along one edgc,` the outwardly bent lower end 10, the finger 11 near the lower end -and thel'extension 12 at the upper end. This brace is loosely pivoted on a screw 8, which as'shown in Figs. 1, 2 and 3, is secured in' the side edge of the lid,l and as shown in Fig. 4, is secured in a de ending bracket4 18 onthe under side of the Pivoted on thesideof the box near its upper edge is a latch 10 which consists of a metal plate formed with a rearward portion adapted to engage the teeth 9, with a lower extension 16 and with a forward extension 17 the end of which is slightly offset to form a suitable grasping portion.
lPlaced over the latch and secured to the side of the box, is a plate 13 which is bent to form a housing for the latch anda slideu-'ay for the brace, one bend forming an inclined shoulder 14`and the other bend forming a shows in elevation t e relative osition of the' the extension 17 and thus .servesto' normally retain thel latch in operative ositio. "i
The construction and re ative arrange-' ment of the brace and latch is such that', as',
the lid 6 is raised, the curved upperside of the teeth 9 bearing againstthecurved lower edge of the latch partially turn the latch on c .is'pivgoedniliis center so that the rear portion oyerbalance's'-.-

its pivot, when the lid being. released by the person raising it, the straight side of the teeth coming in -'contact with the upper straight edge of thelatch will cause 'the latter to drop into .its locking position and thus hold the brace and its lid against downward movement, the vangle at which` the lidy -is helddepending upon the position of the notch or tooth engaged bythe latch.
If it be desired to release the latch, the lid i can be raised. toa vertical position as shown in Fig- 3,- whereu on the tin 'er 11 striking the under side of t e latch Wil trip the latter and throw it upwardly and forwardly'so that its greater weightwill be on the front side of its pivot thus holding the latch in the position shown vin will be seen that t e brace teeth are entirely F' 3. In this-position, it
disengaged from the latch and that suc condition will revail while the lid is-being closed, until t e ndof the' extension 12 strikes the-end of thelatch, whereupon the latter will be restoredv to its normaler openttive position.
It will 4be apparent that the bent'lower ortion of the brace strike against the inclined shoulder 11 of the housing plate and thus cause the finger to 'contact with the latch and throw the latter to the position indicated in Fig. 3.
-Tliis device ma be connected with the inside or the outsi e of the box to which it is attached, and various changes may be made in the details of construction and manner of attaching. I therefore do not wish to be limited to the precise details shown, but
What I claim, is':- 1. A supporting device consisting of a pivoted brace having downwardly extending projections at its upper end' and near its lower end and with teeth intermediate said projections, and a pivoted gravity operatin latch adapted to engage said teeth to hol the brace in-its adjusted positions and to be engaged bv said downwardly ez/rtenling-pro-A 15 said .brace in one direction.
jectioristo be thiown into operative and inoperative positions.
` 2. A supporting device consisting of a pivoted brace having downwardly extendn 5 ing projections at its upper end and near its lower end, a lateral projection at its lower end, and teeth intermediate said downwardly. extending. projections, a pivoted latch mem- .ber adapted to engage said teeth to hold the- 10 brace in its adjustedV positions and to be en gaged by said downwardly extending ro- ]ections .to be thrown into operative an inoperative positions, and means engaging said lateral `projection to limit the movement of ing .of an adjustable brace pivotlly con nected with said device and having teeth along one edge and a lateral projection at its lower end, and formed with extensions', a pivoted latch adapted to engage said brace and hold it in itsadjusted positions, and"to be e aged by said extensions',` and a housing for said latch, said housing forming a stop for said latch and a slideway for said brace, substantially as sltxlown.
