MURRAY SQ OEISM, OF PHILADELPHIA, PENNSYLVANIA.

INSTRUMENT-CASE Specification of Letters Patent.

Patented April 27, 1909.

Application filed. May 29, 1908. Serial No. 435,822.

T 0 all it may concern: Be it known that I, MURRAY S. CrnsM, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Instrument-Cases, of which the following is a specification. V

This invention relates to instrument cases,

and hasfor its object the production, for example, of an eyeglass case embodying parts of special construction and particular arrangement, whereby it is believed the cost view showing the relatively straight side of the device. Fig. 3 is a cross-section upon the l ne xa: of Fig. 1. The scale of drawing in Figs. 1, 2, and 3, is greater than actual size to more clearly exhibit certain features of the construction. Fig. 4 is an end view of an eyeglass case constructed in accordance with this invention. Fig. 5 is a front view of the case with the flap open, and Fig. 6 is a 1 horizontal section on ne yy of Fig. 5.

Like reference letters are used todesignate the same parts throughout the description and drawin s.

The flap 2, the back B, and thefront C of the case are parts of the same flexible sheet, and the flap and front are caught together when the case is closed, by the snapbutton and socket D and d.

The end-closing device E has, as ordinarily constructed, a depressed middle portion, best shown in Fig. 3, and a groove extending around. the edge. The outer wall of the groove s marked F and the inner wall G. The wall F has two tangs f and f that are intended to pierce the fabric and to be clenched inside the case, as shown in Fig. 6, for the purpose of retaining the device in position.

To apply the end-closing device in the construction of this invention, the front C of the case. is bent upwardly parallel to the back, and the edges of the front and back introduced into the groove of the device. The tangs are passed through the fabric and clenched on the inside, and the walls of thegroove are pressed toward each other clamping the edge of the fabric between them.

Where the construction relates to an eyeglass case as illustrated, and the front 0 is less in width than the back, the wall F of the end-closing device is turned in to the wall G. Thus, the upper portion of the end-closing device presents a rounded curved surface when the case is opened and gives a finished ap earance thereto.

Iaving now described my invention and explained the mode of its operation, what I claim is 1. A case, comprising a front and back of flexible material and non-metallic, a flap connected with the back and adapted to close upon the front, and end-closing devices having a groove adapted to engage the edges of the said front an back, the said end-closing devices being constructed of a substance capable ofretaining its clutch when the said groove is inched upon the edges of the said front and ack, substantially as described.

, 2. A case comprisin a front and back of flexible and non-metallic material, the said front and back comprising a sheet of material bent to formthe bottom of the case and end-closing devices having a groove ada ted to engage the edges of the said front and ack and hold them apart, the said endclosin devices being constructed of metal capab e of retaining its clutch when the said groove is pinched upon the edges of the front and back, substantially as described.

I 8. An end-closing device for cases, comprising a middle or body portion having a groove extending around it, the said groove having an outer and an inner wall, the said device being constructed of bendable and relatively inelastic metal whereby the walls of the groove maybe closed upon an edge of material inserted in the groove and maintain their clasp thereof, and a portion of the outer wall of the groove being turned inwardly over the groove, substantially as described.

4. An end-closing device for cases, comprising a middle or body portion having a groove extending around it, the said groove having an outer and an inner wall, the said outer wall being higher than the inner wall, the said device being constructed of bendable and relatively inelastic metal whereby the walls. of the groove may be closed upon an edge of material inserted within the groove and maintain their clasp thereof, and a portion of the outer wall of the groove being turned inwardly over the groove, substantially as described.

5. A case comprising a back and front of flexible, non-metallic material, the front of the said case being less in width than the back, and an end-closing device having a groove adapted to engage the edges of the back and front of the case, the said groove having a front wall and a rear wall, a portion of the said front wall above the longitudinal edge of the said front of the case being turned inwardly toward the said inner wall, substantially as described. 15 In testimony whereof I allix my signature in presence of two witnesses.
