' IsADoEE EISENSTARK AND BERNARD Lrrs'rrrrz, OF BROOKLYN, NEW YORK.
Application filed July 14, 1924. Serial No. 725,771.
To all whom it may concern:
Be it known that we, ISADORE EISENSTARK and BERNARD LIP'SHITZ, citizens of the United States, and residents of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Cigarette Cases, of which the following is a specification.
This invention relates to cigarette cases. Its object is to make acompact, leather cigarette case having two cigarette holding compartments spaced apart by a straight, flat, taut and non-wrinkling partition of flexible material, the non-wrinkling and other characteristics of the partition serving to prevent breaking of cigarettes in the compartment at either side thereof; the case having semi-rigid, permanently swelled out back and front sides which serve to minimize danger of breaking of contained cigarettes, and the swelled out front and back sides being stretched in swelled out position to hold the partition fiat and straight and to keep it from wrinkling.
In the accompanying drawings forming a part hereof and illustrating the invention,
Fig. 1 is a front elevation of the case with its folding cover flap open and cigarettes in place.
Fig. 2 is a sectional View of the case at line 2-2 of Fig. 1 showing the outer or back and front walls of the case and the par-- tition, and two rows of cigarettes, one in each compartment.
Fig. 3 is a flat plan view of the case in process, its folding cover flap being shown Open.
Fig. dis a transverse central section of what is shown in Fig. 3 at line 4-4: of Fig. 3.
Fig. 5 is a view of the structure shown in Fig. 3 assembled with a duplex, hot-mold having a pair of rigid molding tongues provided with parallel, rigidly spaced apart, partition engaging faces.
Fig. 6 is a sectional View of the structure shown in Fig. 5 at line 66 of Fig. 5.
In the drawings, Figs. 1 and 2 illustrate the completed case which is made up of a leather back piece 1 having. an integral, folding cover flap 2; a front piece 3 provided preferably with a cross loop 4 for holding the free end of the folding cover flap in covering position over the open, upper portion of the case; and a fiat, straight taut, non-wrinkling partition 5 preferably of leather, but which may be of any other suitable, sewable material. Partition ,5 separates the case into two pockets or compartments each for a row of closely fitted cigarettes X, the upper ends of which are exposed for access at both sides of the partition and at the mouth of the case under.
the bend of the foldable cover flap.
The cover flap 2, which is integral with the back piece, is freely flexible, but the back piece and the front piece 3 are each swelled outwardly and permanently shaped as outwardly swelling, semi-rigid case sides and caused to hold the partition in straight, flat,
taut and non-wrinkling condition, as shown,
back and front sides are the samelength,
the opposite end edges of the three plies in the assemblage being flush. The under edge of the partition is free; that is, is not carried. in between the bottom, superposed margins of the back andfront pieces. dition the ends of the assemblage are stitched together at Y, whereby the opposite ends of the partition are marginally secured to the united end margins of the assemblage, the line of stitching uniting the directly superposed bottom margins of the front and back pieces. In this condition the back piece and the front piece lie fiat respectively against a side of the partition.
In the assemblage indicated in Figs. 3 and 4;, the cover flap receiving loop 4:, which is a preferable form of member for securing the cover flap in closed position, has its end margins superposedly in place, the loop extending lengthwise of the front piece and the ends of the loop being stitched in place by the line of stitching Y.
A hot-mold A, usually of brass, and heated when in use, is provided with two opposed, stiff molding tongues a the inward faces of which are flat and parallel and form the walls of a partition receiving slot a.' The outer edges of the tongues are rounded as at a along the bottom and also along their In this con-- nent set of the front and back pieces in the swelled out, compartment forming sides. The tongues are of like dimensions and contour and consequently the compartments are correspondingly formed. The heat causes the leather to become set in its distended or stretched position and as the front and back sides are stretched outwardly they are lengthened, as indicated in Figs. 1 and '2, so that they hold the partition straight and free of a wrinkled condition by the'presence of which cigarette wrappers would become cracked or bro-ken. By the semi-rigid condition of the front and back walls it is meant that they are permanently and, normally swelled out. It is not meant that they are not compressible each against the partition. They are selfsustaining in their stretched out, swelled and permanently set condition.
'So far as we know, our product, indicated method and duplex mold: having rigidly spaced apart, partition embracing walls are severally new.
By molding the front and back sides simultaneously with the partition enclosed be tween the fixed, parallel mold surfaces, the partition is kept fiat, straight and taut and the outer walls of the compartments may be tained in proper relation to the partition to keep two rows of cigarettes upright, as
indicated in the drawings. The lower, free edge of the partition is indicated by p.
lVhat we claim is:
In the process or" manufacturing leather c-onipartmental cases, the process step of mechanically assembling a superimposed, fiatwise contacting, n'iarginally united, leather back side and leather front side with an intermediate partition of flexible material; in inserting between the partition and each of sa d sides, a. tongued hot-mold having rigid molding tongues and an inermediate partition receiving slot the faces of which are parallel; in simultaneously stretching and shaping said sides and maintainingthe partition straight, and lengthwise tautcning said partition; and in causing said stretched and shaped sides to become set by the heat from the hot-mold.
