HINGE.

Application filed April 25, 1923. y Serial No. 634,414. ,l

To all iii/0my t may concern.'

Be it known that I, CHARLES N. CoiirnLL, residing at Mainaroneck, in the county of Wvestcliester, State of New York, have invented certain new and useful Improvements in Hinges; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a hinge construe tion particularly adapted for use in connection with closures on small receptacles.

The ordinary hinge consists of interlitting and aligned knuckles, designed; to swing about a common pintle. To employ such a hinge in mounting covers on small boxes necessarily involves providing both body and cover with hinge knuckles. I/Vhere the parts are of metal these knuckles may be soldered on or made integral with the part with which they are to function; but in either event, production difculties are involved, and when the box is an article of iewelry its appearance is not improved. The object of this invention is to minimize these diiiiculties; devising a cheaper hinge construction for closures on small receptacles, while at the same time making a better looking and neater joint. I have done this by providing only the body part of the receptacle with a knuckle and pintle, while curling an edge of the cover to embrace the piutle ends and perform the function of a. knuckle. The curled edge is cut away for a space corresponding` to the knuckle, and 'the curvature of the knuckle, made substan tially that of the cover edge, so that when the cover is closed the hinge is hardly noticeable and thus does not detract from the ap pearanc'e of the box.

In order that the parts may be easily assembled, the curled edge of the cover does not completely enclose the pintle, but extends only half-way around it. In assembling. the projectingr ends of the pintle are moved transversely under the curl of the cover edge, and when the cover is swung open the knuckle itself prevents disengagement and the parts are interlocked. To prevent disengagement when the cover is returned to assembling position, I provide the cover with a bezel, or its equivalent, which is slipped into place after the parts have been assembled, and the cover swung Yinto interlocking positoi In the accompanying drawings,- vI have illustrated a small vanity case or boi;v embodying the invention. 'Inthese drawings, 4

cover being shown` in wide open position; Fig. 4 is a transverse section taken alo-ng line 4`4 of Fig. 3, `and showing one means for locking the cover in position; Fig. '5 is a vertical section `taken"along line 5 5 of Fig. 3, showing moreclea'rlyfthe relation of tliehinge parts; and Figjisa ysection simi# lar to Fig., 4 but showing' a bezel` for lock,`

One ofthe side walls4 one end of the cover are designed to enclose the extending ends of the pintle, the edge at this end being cut away to form an open slot 9 slightly longer than and designed to receivethe knuckle, to permit the cover t0 swing aroundit.

. To assemble the parts. the cover is placed' upon the body and slid longitudinally until the curled edge embraces the extending ends of the pintle and the hinge knuckle lies within the slot cut for it. The cover is then swung open and the ing position. K

If the cover were never to be closed again, this would be sufficient, but when closed, it is clear that a reverse slidingmovement would disengage it. necessary to place some lockingmeans within the cover. As shown in Figs. l', 2, 3 and"A and 4, the frame l0 which holds thepowder and rouge compacts serves to performthis function. As shown in Fig. 6. I may substitute a bezel 1l in place of the frame l0.

for preventing longitudinal movement ot.

the cover relative to the pintle.

The hinge construction shown is simple and effective, is much less expensive to pro- To prevent this, it

parts are in interlock# duce in quantity than the ordinary twoknuckle hinge, and when used in connection with small receptacles, such as shown, produces a very neat appearance, the hinge itl'other member designed to receive the ends of thepintle transversely during assembly vand tobe swung into interlocking position,

the curled edge being provided with an open slot slightlylonger than and designed to lreceive the knuckle, and means for lecking the parts against disengagenient when inassembling position.

' a curled edge, on the .cover designed to receive the ends'o'f the pintle transversely when the ycover is closed and forni an interlocking joint when open, the curled edge being provided 'with an open slot slightly longer than and designed to receive the knuckle, the base of the slot co-operating with the knuckle 4to prevent disengagement of the cover is open, and means held` a cover, the combination of' a hinged knuckle 4on the body, a pintley coaxial therewith extending beyond tlie knuckle at both ends, a curled edge on the cover designed to receive the ends of the pintle transversely when the cover is closed and to 'form an interlocking joint when open, and a compactl iframe within the cover for preventing transverse movement ofthe cover relative to the pintle, thus locking the parts against disengagement when closed.
