CIGAR-MOLD.

SPECIFICATION forming part of Letters Patent No. 560,577, dated May 19, 1896.

Application filed May 25,1895. Serial No. 550,(364. (No model.)

To all whom it may concern:

Be it known that I, NAPOLEON DU BRUL, a citizen of the United States, and a resident of Cincinnati, in the eounty of Hamilton and State of Ohio, have invented certain new and useful Inprovements in Cigar-Molds,of which the following is a specification.

My invention is an improvement on that Construction of cigar-mold for which Letters Patent No. 538,1S9 were granted to me on the 23d day of April, 1895, and in which the middle portion of the sides of the upper cup are gradually cut away or reduced in height so as to permit the middle portion of the bunch to expand or swell beyond the circular molding-chamber.

Heretofore cigar-molds have been formed with lower and upper cups, having their molding faces or cavities of semicircular form in cross-section, so that when they were brought together they would form a true circle. In this Construction of cigar-mold there is no provision for the expansion of the bunches' formed therein. To permit the middle portion of the bunch to expand was the object of the Construction described and claimed in the said Letters Patent hereinbefore referred to; but I have found that while this Construction of cigar-mold is a great improvement on cigarmolds heretofore constructed, yet a certain disadvantage exists in the sharp corners which are produced and left in this form of cigar-mold and which are liable to leave marks on the bunches formed therein. To overcome this disadvantage is the object of my present improvement, which consists in gradually increasing the size of the molding face or cavity of the upper cup in width and height between the ends from a semicircle at said ends to a segment of a circle of a larger radius or width than the semicircular molding face or cavity of the lower cup, and which segment of a circle extends into the sides of the upper cup and thereby gradually enlarges the molding face or cavity and reduces the height of said sides at the middle portion of the cup, thus leaving fin edges instead of abrupt corners, between which the bunch is permitted to expand or swell, and producing a moldingchamber of approximately oval shape in cross-section between the ends of the molding-chamber.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure I is a central longitudinal section of a portion of a cigar-mold, showing a transverse section of my improved cup. Fig. II is a transverse section of the upper member of the cigar-mold, .showing a central longitudinal section of the cup. Fig. III is a transverse section of the upper member of the cigar-mold, showing a side view of the cup. Fig. IV is a face view of the cup. Fig. V is a transverse section of the upper member of the cigar-mold, showing a side View of a modified form of cup in which the middle portions of the sides are gradually reduced in height until they are fiush with the cupsupport.

l is a portion of the lower member of a cigar-mold, provided with matrices or lower cups 2 of any approved Construction.

3 is a portion of the upper member of a cigar-mold provided with my improved form of upper cup 4, which is adapted 'to fit the matrix or lowes cup beneath it and approach the semicircular molding face or cavity 2, and forming in connection thereith a com-' bined circular and approXimately oval molding-chamber. Each upper cup 4 is preferably forned with the customary supportingfianges 4:, whereby it is Secured to theupper member of the cigar-mold. The sides l are reduced in height or cut away between the ends, as in my said Letters Patent hereinbefore referred to; but instead of cutting away the molding face or cavity at the middle portion of the sides so as to contract it, or removing the middle portion of the sides with the sides of the molding face or cavity, I gradually enlarge the molding face or cavity from the points 43, so as to produce a molding face or cavity 4: of increased depth and width between the ends in the shape of a segment of a circle of greater diameter than the circle of the molding face or cavity of the matrix with which it coperates.

In Figs. II and III, I have shown the niddle portion of the sides partly reduced, and in the modification shown in Fig. V, I show the middle portion of the 'sides reduced or cut away as far as the support 3 but in both IOO instanees the nolding face or cavity extends to the outer or fin edges of the sides of the cup. This Construction of molding-chamber allows the middle of the bunch on the toptoexpand or swell up and form an oval launch. Though it forms an oval bunch, yet when the wrapper is put on the cigar is rolled round and better initates a hand-made cigar than other cigars made in molds. The segmental depression may vary in depth and may gradually start more or less close to the ends of the cup. Then a bunch is made the size is gcnerally regulated by the size of the lower cup, the bottom of which is a true half-circle, and it 'follows, by means of this gradual enlargement of the half-circle of the upper cup into a segment of a larger circle, that when the cup is placed in the lower cup a moldingchamber partly circular and partly elliptical in form, is produced. The bunch having' been rolled down to near the proper size of the size of the circle of which the moldingface of the lower cup forms one-half, the upper cup does not press the bunch as much as if the molding-face of the latter was a half-circle in cross-section. By this Construction of upper cup I remove the side edges and relieve the side pressure that would take place in the ordinary form of cup, and this side pressure being removed allows the bunch to expand at the center while the ends of the hunch are practically pressed round, giving shape to the cigar.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. An upper cup i'or a cigar-mold having the middle portion of its sides cut away, so as to reduce the height of said sides without reducing` the width of the molding-face of the cup, at the middle portion thereof, and thus providing when the cup is in operative engagement with its matrix a gradual enlargei ment of the molding-cavity from the ends toward the central portion thereof for permitting the expansion of the middle portion of the buuch and providing fin edges throughout the entire extent of the sides,substantially as described.

2. An upper cup for a cjgar-nold having the middle portion of its sides cut away, so as to reduce the height of said sides without reducng the width of the moldiig-faee of the cup at the middle portion thereof, and thus providing when the cup is in operative engagement with its matrix a gradual enlargcment of the molding-cavity from approximately half-circles at the ends to a less are of a larger circle at the central portion thereof for permitting the eXpansion of the middle portion of the buneh and providing fin ed ges throughout the entire eXtent of the sides, substantially as described.

3. An upper cup for a cigar-mold having its ends in the form of ares of small circles, sides gradually reduced in height without rcducing the Width of the molding-face of the cup between the ends thereof, and a noldin gcavityforming a less are of a circle of larger diameter, at the red uced portions of the sides, thus providing when the cup is in operative engagenent With the matrix, a gradual eulargcment of the molding-cavty for permitting the expansion of the middle portion ol' the bunch and providing fin edges throughout the entire extent of the sides, substantially as described.

4. A cigar-mold comprising a matrix, and an upper cup providing when the cup is in operative engagement with the matrix a gradual enlargement of the molding-eavity from an are of a circle at the ends to a less are of a larger circle between the ends of the cup and forming an approxinately oval moldiugehamber in connection with the molding-cavity of the matrix at the middle portion thereof for permitting the expansion of the middle portion of the bunch and providing fin edge-s throughout the entire extent of the sid es, suhstantially as described.
