This invention relates to improvements in jewelry cases and its purpose is to provide a novel and useful method for forming an improved case adapted for use as a container 5 for watches, jewelry, pens and pencils, and various other articles. The principal object of the invention is to provide for conveniently and readily forming at small cost thevimproved jewelry case herein described by '10 stamping and punching from sheet metal a box body member or frame member inwhich the parts necessary to the formation of the complete box or container may be readily assembled without the use of auxiliary fastenl5 ing means. -In my separate application for patent filed as a division of this application on une 20, 1929, Serial No. 372,260, for improvement in sheet metal boxes, I have presented claims for the improved box or case which will herein be described.

The nature of the invention will be understood from the following specification taken 'with the accompanying drawings in which the form of the improved jewelry case above referred to .and my improved method of forming the same are illustrated. In the drawings, p Fig. 1 shows a-perspective view of the sheet metal blank from which the frame structure. of the box or lowerpart of the jewelry case is form%l;.

Fig; 2'is a perspective view of the sheet metal blank after the first punching operation has been performed thereon in the process of making the frame structure of the container and after the covering material forming the exteriorfinish of the box body has beenapplied, a portion of this covering material being broken away to show a depres- 40 sion formed in the metal blank to accommodate' the roll of the hinge"of\thebox;

/ Fig. 3' is a perspective view similar to that of Fig. 2 showing the arrangement of the parts after the next succeeding punching .45 operation of the covered-blank;

' Fig. 4-is a perspective view simila'rto that of Fig. 3 showing the relative arrangement of the'parts after a stillfurther punching and .bending operation has been performed on the covered .sheet metal structure;

Fig. 5 is a perspective View showing the structure illustrated n Fig. 4with the cover and hinges of the 'case applied thereto and with an outer lining applied on the inside of the box;

Fig. 6 is a 'cross-sectionalyiew taken at right angles to the axes of the hinges illustrated in Fig. 5;

Fig. 7 is a perspective view similar to that of Fig. 5 showing the complete jewelry case In the manufacture of thejewelry case by the method of the present invention the first step is-the formation of the frame structureof the box body or lower portion of the case 'to which a hinged cover is subsequently to be 'applied. Instead of forming this box body from cardboard or the like accordingto the practice heretofore usually prevailing, the present invention contemplates the formation of such body member from .a flat sheet of metal 10 having the rectangular form illustrated in Fig. 1, although other forms of the sheet metal blank may be employed where the shape of the final jewelry case is to be other than rectangular. After cutting the blank 10to the proper size, the next operation is to place the blank in a suitable vdie punching machine or the like and, by a single punching operation, project the lateral edges of the blank downwardly and outwardly, and

also form the depressions,aa for the hinge roll. At this stage of manufacture the blank.

is covered with the covering 21 of leather,

outwardly'and downwardly in straight lines I 45 flanges 15 and '16 and having its upper edges from the central portion 11 and in the com:

pleted box forms the inclined outer walls of the box body. Obviously the

flanges

12 and 13 may be formed on curved lines, if desired,

therein bounded by inwardly directed flanges on its four sides. The flanges on the longer sides of the opening 14 hai e inwardly projecting extensions 15 while the flanges at the ends of the opening 14' have inwardly directed extensions 16.' In addition, the flange along one of the longer sides-of the opening 14 has a plurality of openings 17 punched.

' therein to form small upwardly directed tongues 18. a The next operation-in the formation of the body member of'the case. is to bend the flanges around the opening'14 downwardly while at the same time projecting the extensions 15 i and'16 inwardly in a horizontal plane, as

shown in Fig.4, wherethe flanges have been j bent downwardly-into vertical planes to form opposite inneriside' walls 19 and'transverse,

inner end walls 20. The-flanges 15 extend inwardly in a horizontal plane from the walls 19 while the flanges 16 extend horizontally inward in the same plane from the end walls 20. At the same time, the small tongues 18 have been. caused to roject inwardly above the position occupied y one of the flanges 1-5. This represents the final formation of thelower frame structure of the ,body of the case and the

flanges

15 and 16 are adapted tosup port certain parts of the completed box;

' As shown in Fig. 5 of the drawings the edges of the covering material 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 terminating substantially flush wit-h the upper edges 23- of the surrounding frame to which the covering 21has-been applied The ends'22" of the lining member 22 areprefere,

abl secured in place by glue or the'like is further shown inFig. 5, the partially completed case also comprises a cover 25' having a top wall-member 25 bounded'by' an integral 'surrounding flange 25" which 'is formed by punchin a sheet inetalplate to project the surroun ing flanges transversely thereto. At thesame time the top wall 25 may be punched to form a rectangular elevated portion 25%, This cover has a layer of leather, imitation 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 125 are adapted-to coincide with the edges 23 of the lower boxframe when the cover is closed. The lower frame structure and the cover 25 are secured together b hinges 27 and each hinge member is provi ed with apertures adapted to be engaged by the tongues 18 formed on the lower frame and by the other tongues 28 formed on the cover. The tongues on the cover are formed by punching in the same way that the tongues 18 were formed and after the hinges 27 .arefitted in place with. these tongues enga 'ngthe apertures therein, the 3 tongues are ent transversely to hold the hinges firmlyin place, the depressions a-a formed in the box body member receiving the hinge rolls to permit a close seatingof the cover upon the box. Each of the pivotally 1 connected hinge members is provided with a notch, as shown at 29 to be engaged by a curved leaf spring 30 havin substantially the form of the letter C with t e 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 h the cover25 in either .an open or closed posit'ion after the cover isswung beyond an intermediate neutral point. In Fig. 6 of the drawings the springsBO are shown as 'servin to hold the, cover 25 in its open position'w ile in Fig. 8 they are illustrated in position to maintain the coverclosed, 4

'Aiter theparts have been formed and as-:

sembled' in the manner illustrated in Fig. 5,

the liningmernbers and jewelry tray or sup the adjacent bottom flange 15 and also the top wall 25* of the cover. After applying glue or paste to thecinsiderof the cover, a cover 'liningmember 33 is then put iniplace overlapping-the outer side of one edge of the A hinge covering 32. This =eover 33 may preferably be a sheet-ofcardboard or a rectangular cardboard frame covered Jvith silk or other material similar to'that formingthehinge covering 32 and upon eng ing the paste or glue applied to the insi e of-the coverlitwill be held in place and will at the same time hold the hinge covering 32 in place by friction. If-the body structure I of the cover lining 33 has'suflicient stiffness and resiliency.. it may. be caused to retain itself in position without employing any glue or other fastening means.

A sheet of" cardboard inner bottom wall is then placed in the bottom of the lower frame structure withits edges resting on

theflanges

15 and 16 and of such a size that it fits closelywithin the outer lining strip 22. One edge ofthecardboard 4 vsheet 34 will rest on t-heedge of the hinge covering32,and hold thelower part thereof in place 'The parts are then in readiness 34 constituting surrounding lining member 2:2.

mg between the surrounding walls formed for the insertion of the jewelry tray or sup-- metal blank to form downwardly extending outer flanges 36' and one or more intermediate depressions 37, the single depression 37 shown in Figs. T and 9 being of suitable shape to receive a wrist watch and-its connected wrist band. The sheetimetal 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 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 havto receive another article of jewelry of different shape. This tray is held in place by gravity and by frictional contact with the The openby the covered flanges12 and 13 of. the box beneath the tray is closed 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 16.0f the box body, adjacent the inner :wall or cardboard sheet 34 resting on top of such flanges, and is glued to such sheet to secure the parts together and complete the box body, the flexibility of the wall members being suflicient to permit a firm glued connection to be made.
