My invention relates to improvements in jewelry cases and like containers and its purpose is to provide an improved case adapted for use as a container for watches, jewelry, 5 pens and pencils, and various other articles.
The present application is a division of my pending application for patent filed January 26, 1928, Serial No. 249,537, and relates to the construction of the box therein described. The principal object of the invention is to provide an improved jewelry case or similar container comprising a box body member or frame structure which may be conveniently and readily formed at small cost from sheet metal, by stamping and punchin and in which the parts necessary to the ormation of the complete box or container may be readily assembled without the use of auxiliary fastening means. A further object of the an invention is to provide a container for articles such as those mentioned comprising a plurality of parts which may be readily fitted together and which retain themselves in their proper positions without being rigidly attached to the frame or box of the container.
Other objects of my invention relating to various features of construction and arrangement of the parts will appear more fully hereinafter.
The nature of my invention will be understood from the following specification taken with the accompanying drawings in which one form of my improved jewelry case is illustrated, and a convenient method of ings,

First briefly describing the method employed by me in forming my novel box, more fully set forth in my pending application, it may be explained that the frame member of the body portion of the box is formed by first stamping the edges of a rectangular blank of sheet metal 10 downwardly and outward.- ly, and also forming in the blank depressions aa for-the hinge roll. The blank is then covered (by use'of a suitable adhesive) with the covering material 21 used to give finish to the box, this material extending around the edges of the side flanges 12 and end flan es 13 forming the outer walls of the box ody, which in the present instance slope dowlnwardly and outwardly, though obviously any other desired contour may be employed. By other operations a portion of the center of the blank is removed from the top portion 11 and tongue 17 and 18 formed on the blank. The blank is then bent to form downwardly 3 extending inner side walls 19 and end walls and inwardly extending horizontal flanges 15 and 16 connected to the bottom of the 1nner walls 19 and 20, res ectively. The edges of the covering materia 21 within the frame structure are protected by a surrounding lining member 22 which is in the form of a band of relatively stiff fabric or other material having its lower edges resting on the flanges 1B and 16 and having its upper edges terminating substantially flush with the upper edges 23 of the surrounding frame to which the covering 21 has been applied. The ends 22 of the lining member 22 are preferably secured in place by glue or the like.
As shown in Fig. 5, the case also comprises a cover 25 having a top wall member 25 bounded by an integral surrounding flange 25 which is formed by punching a sheet metal plate to project the surrounding flanges transversely thereto. The top wall 25 may be formed, as shown, with a rectangular elevated'portion 25. This cover has a layer of leather,.,imitati0n leather or other covering material 26 applied thereto by glue or the like with the edges thereof carried upwardly inside of the flanges 25". The edges of the flanges 25 are adapted to coincide with the efges '23 of the lower box framewhen the cover is closed. The lower frame structure and the cover 25 are secured together by hinges 27 and each hinge member is provided with apertures adapted to be engaged by the tongues 18 formed on the lower frame and by other tongues 28 formed on the cover. The tongues on the cover and frame are bent transversely to hold the hinges firmly in place, the depressions a-a formed in the box body member to receive the hinge rolls serving to permita close seating of the cover upon the box. Each of the pivotally connected hinge members is provided with a notch as shown at 29' to be engaged by a curvedleaf spring 30 having substantially the form of the letter C with the ends thereof hooked about the edges of the hinge members at the bottoms of the notches 29. These spring members are such that they will hold the cover 25 in either an open or closed position after the cover is swung beyond an intermediate neutral point. In Fig. 6 of the drawings the springs 30 are shown as servin to holdthe cover 25 in its open position while in Fig, 8 they are illustrated in position to maintain the cover closed.
In constructing the box, after the parts have been-formed and assembled in the manner illustrated in Fig. 5, the lining members and ajewelrytray or'support are put in place.
A strip; o'fjsilk 32jor the like'is arranged over the-hinges and the hinge joint longitudinally of the ex and of sufficient width to overlap the adjacent bottom flange 15 and also the top wall 25" of the cover. A cover lining m ember33 overlapping the outer side of one edge of the hinge covering 32 is secured by glue or paste to the inside of the cover. This cover lining 33 may. preferably be a sheet of cardboard or a rectangular cardboard frame covered with silk or other material similar to that forming the hinge covering 32 and upon engaging paste or glue previously applied to the inside of the cover it will be held in place and will at the same time hold the hinge covering 32 in place by friction. If the body structure of the cover lining 33 has suflicient stiffness and resiliency it may be caused to retain itself in position without employing anyglue or other fastening means.
'A sheet of cardboard 34 constituting an inner bottom wall is arranged in the bottom of the lower framestructure with its edges resting on the flanges 15 and 16 and of such a size that it fits closely within the outer lining strip 22. One edge of the cardboard sheet 34 rests on the edge of the hinge covering 32 and holds the lower part thereof in place. \Vithin the container constructed as thus far described, is arranged the jewelry tray or support 35 which is-preferably made up of a sheet metal frame 36 stamped from a sheet metal blank to form downwardly extending outer flanges 36 and one or more intermediate depressions 37, the single depression 37 shown in Figs. 7 and 9 being of suitable shape to receive a wrist watch and its connected wrist band. The sheet metal frame 36 of the jewelry tray has an outer covering 38 of plush or the like, the lower edges of which are turned upwardly on the insides of the flanges 36 and secured in place by a sheet 39 of cardboard or sheet metal. The plush lining 38 conforms to the contour of the depression 37 which is enlarged at one end as shown in Fig. 7 to receive the watch. This jewelry tray preferably has a tab 40 attached to the side thereof so that it may be pulled upwardly and replaced by another tray having a depression of different conformation to receive another article of jewelry of different shape. This tray is held in place by gravity and by frictional contact with the surrounding lining member 22. The opening between the surrounding walls formed by the covered flan es 12 and 13 of the box beneath the tray is c osed by an outer bottom wall 41 made up of a sheet 41' of cardboard or sheet .metal having a covering 41" of leather or the like applied to the lower surface thereof. This outer bottom wall 41 lies immediately below the flanges 15 and 16 of the box body,
adjacent the inner wall or cardboard sheet 34 resting on top of such flanges, and is glued to such 5 eet to secure the parts together and complete the box body, the flexibility of the wall members being sufficient to permit a firm glued connection to be made.
Although one form of the inventon has been shown and described in connection with one method of forming the improved jewelrv case, it will be understood that the invention may be embodied in various forms and practiced in various ways within the scope of the appended claims.
