UNlTE amnion or MAKING VANITY cases.

Application filed June 6,

This invention relates to the method of making and has for its object to provide a method of making a case haying body and lid members hinged together,-each formed from a single piece of sheet stock with outturned meeting edge flanges.

A further object of the invention the method whereby a plurality of different desired appearances may be formed by merely changing the shape of outline of the box by differently trimming the edge flanges.

A still further object of the invention is the method of forming a hinge such that all of the hinge fingers on each member are so located that the group of fingers is at one side of the center with the edge of one of the fingers of the group on a line passing through the middle of themember so that when the members are oppositely positioned the hinge eyes will be in staggered interlocking relation to cooperate to receive a hinge pintle for connecting them together.

lVith these and other objects in view, the invention consists of certain novel features of construction, as will be more fully de scribed, and particularly pointed out in the appended claims.

cases with different effective appearances and to form the same by a method having simple operations and by which different shapes maybe obtained without altering the entire set of tools for constructing the box,

1 form the body and lid members with out- I turned flanges and provide different shaped trimming tools for differently shaping the edge flanges to obtain this result and as the flanges lie in substantially a single plane they meet to eliminate the inaccuracy of so hinging the body and lid members together as'to close over the other; and the following is a detailed description of the present embodiment of the invention disclosing one method by which a construction having these advantageous results may be obtained,

With reference to the drawings, 10 desig-- nates a blank which is formed having an outline which is in general the shape ofv the finished box. This blank is pressed between J suitable tools to. form a shallow cup-shaped portion 11 with an outwardly-extending edge flange 12. After this pressing operation, the member is then struck with a drop hammer to further or deeper draw the cup and at the same time to impress therein any suitable design such as that illustrated at 13 in Figure 1. The next step in the operation of forming the box is to trim the edge flanges 12and at the same time formthe catch and hinge fingers. The edge flanges and hinge fingers are trimmed the same in outline with a suitable cutter this being pos sible by the position of the hinge fingers as shown but the catch differs by having a male and a female portion, one portion carried by each of the box members which necessitates that the trimming tool of each portion of the box be different.

the case'which has its edge flanges 12 trimmed to form scallops 13 aroundits periphery with hinge fingers 14c, 15 and 16 at one side, which group of fingers have their mid point at one side of-the center line 17 passing through the edge 18 of the finger 15. The catch portionof the male member shown in Figure 5, is formed by the detent 19 extending from a point diametrically opposite to the hinge fingers as clearly illustrated in the drawing. The female member of the box has its edge flanges 12 trimmed to form scallops 13 with hinge fingers 20, 21 and 22 located as are the fingers 14, 15 and 16 in the male member and the female por the box are disposed opposite to each other with the cup portions facing, as illustrated in Figure 7, as'the groups of hinge fingers are off centre a distance equal to the width 7 of one of the fingers the fingers of one group Will be staggered with relation to the fingers of the other group so that two of the hinge fingers 20 and 21 will lie between the hinge fingers 14.- and 15 and 15 and 16, respectively.

After the hinge fingers are disposed in staggered relation, all of the fingers are then rolled about a hinge pintle to. hingedly connect the oppositely disposed body and lid members together.

The projection 27 is raised or struck from the stock of the detent 19 to snap over the edge 28 of the female portion of the catch to resiliently retain the hinge members in closed position, it being understood that the end portion 29 of the detent is of sufiicient extent to permit engagement of the finger nail to spring the same up over the edge 28 for releasing the members to swing on their hinge to open position.

In some instances, I may form the box with a cup-shaped portion 30 circular in shape and trim the edge flange 31 into octagonal form 32, as illustrated in Figure 10, or any other desired shape to obtain different appearances of the boxes by merely varying the trimming tool and thus utilize the many foregoing tools used by this method to give to the boxes different appearances in their final formations.

It will be observed that I have provided a method of forming a box which permits of many various shape-s produced by trimming of the edge flanges from a set of tools for forming the boxes by merely varying the v shape of trimming tool in the final operation which is accomplished by the providing of an outwardly extending flange from the cupped body of the sufficient extent to permit of such varying trimmings.

Having thus described one illustrative embodiment of my invention and the best mode known to mefor carrying out my method, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense, and not for the purpose of limitation, the scope of the invention being defined and limited only by the terms of the appended claims.

I claim: 7

1. A method of forming the body or lid of a vanity case, which consists in drawing a blank of sheet stock to form a shallow cup with outwardly-extending flanges, and trimming the flanges to form them into a shape having a general symmetrical outline different than the shape of the cup so that the distance from the edge of the cup to the edge of the flange varies at difl'erent points around the periphery of the case. 7

2. A method of forming a body or lid member of a vanity case, which consists in cutting a blank from sheet stock, pressing the blank to form a shallow cup with outwardly-extending flange, striking the shallow cup to ornament and further draw the same, trimming the flange to the desired shape with hinge arm-s and one part of the fastening catch.

3. A method of forming a vanity case, which consists in cutting a pair of blanks from sheet stock, pressing the blanks to form shallow cups with outwardly-extending flanges, striking the shallow cups to ornament and further draw the same, trimming the flange of one of the members to the desired shape with hinge fingers and the male portion of the fastening catch, and trimming the flange of the other member to the same shape with hinge fingers and the female portion of the fastening catch, and rolling the hinge fingers of both of said members about a hinge pintle.

4. A method of forming a vanity case, which consists in cutting a pair of blanks from sheet stock, drawing the blanks to form shallow cups with outwardly-extending flanges, trimming the flanges to form a plurality of hinge fingers spaced apart a distance equal to their width with the group of fingers at one side of the center and with the edge of one of the fingers on the center line, reversing one of the members to oppositely dispose the cups and stagger the hinge fin gers, and rolling the fingers over a hinge pintle.

In testimony whereof I affix my signature.
