CARBCASE AND METHOB OF MAKING SAME.
Application filed February 25, 1927. Serial No. 170,759.
This invention relates to improvements in card cases and the method of making the same.
The object of the present invention is to
ft reduce the number of parts entering into the manufacture of card cases to a minimum and thereby reduce the labor required in the manufacturing process, so that the ultimate cost of production may be lessened.
10 Another object of the invention is to produce a card case of extreme thinness, so that a large number of leaves may be enclosed in a small space.
A feature of the present invention is the
15 extending of the celluloid forming the windows of the card case throughout the entire length of the device which insures a uniform thickness of material, so that the parts may be easily sewn together during assembly.
20 Another feature of the invention is the formation of the two celluloid windows from a single strip of material, so that the number of handling operations during assembly may be reduced to a minimum and
?<-r> proper registration of the parts may be assured.
With the above and other objects in view, the invention consists in the novel construction, combination and arrangement of parts, 30 which will be fully set forth in the following specification, claimed, and illustrated in the accompanying drawing in which:—
Figure 1 is a perspective view of a card case, the leaves of which are constructed in sri accordance with this invention,

Referring to the drawings in detail, the body of the device designated generally by the numeral 25 comprises a sheet of flexible material, stamped out in blank form to provide side members 26 and end members 27. These side members are connected midway of their length by an integral web 28 for a purpose to be more fully hereinafter described. Connecting the side members 26 at a point intermediate, the web 28 and the end members 27 is a bar 29 connected intermediate its ends by means of a bar 30 to its respective end wall. Each side and end member is provided along its outer marginal edge with a flap or extension, the corners of which are cut out as at 31, so that when the flaps are folded over into planes parallel'with the members 26 and 27, their corners will miter together rather than lie in overlapping engagement.
Cooperating with the body 25 is a blank of sheet material, such as celluloid or the like, which is of an external dimension to register with the outer edges of the side and end members 26 and 27. This blank as illustrated in Figure 3 i,? provided with a cen
