FREDRIOK O. MILLER, OF NEWVPORT, KENTUCKY, AND HENRY (J. PETERS, OF NEXV YORK, N. Y.

CIGAR-MOLD.

SPECIFICATION forming part of Letters Patent No. 234,796, dated November 23, 1880.

Application filed September 13, 1880.

To all whom it may concern:

Be it known that we, FREDRICK 0. MILLER, of Newport, in the county of Campbell and State of Kentucky, and HENRY O. PETERS, ofNew York, in the couutyof New York and State of New York, both citizens of the United States, have invented certain new and useful Improvements in Cigar-Molds, of which the following is a specification.

Our invention relates to an improvementin cigar-molds; and it consists, first, in a cigarmold lid provided with inverted-cup-shaped plungers, which are made of elastic material and adapted to be employed in connection with the ordinary matrices; second, in an ini erted-cup-sha ied plunger for a cigar-mold made of india-rubber or other suitable material. The plungers are made of elastic material, such as rubber, gutta-percha, or eelluloid, which has sufficient rigidity to press and shape the bunches, and yet has sufficient elasticity to allow the edges of the inverted cup shaped plunger to yield under strains caused by lifting one end of the lid higher than theother without breaking the edge of the cup, the cups having thin strong edges that do not readily break from blows or strains.

Our invention further consists, third, in a cigar-mold having a series of matrices made in wood or other suitable rigid material and lined with a thin elastic lining; fourth, in the combination of a cigarmold lid having a series of elastic invertcd-cup-shaped plungers attached to a rigid backing with a matrix block the cavities of which are lined with thin elastic material, all as hereinafter more fully set forth. By lining the series of matrices with elastic material the said lining will yield to the pressure of the cups without breaking the edges of the latter.

Our invention overcomes several difliculties experienced in the use of wooden and metal molds hitherto used in the manufacture of cigars. In order to produce fine work a close fit ting of the edges of the cups to the sides of the matrices is necessary, and the edges of the cups must also be quite thin or sharp. It has been found impossible to obtainboth of these features with wood or metal and yet insure durability.

(No model.)

The bunches of tobacco are pressed when moist, and when wood is used for the cups or matrices it swells and it is liable to break in the act of removing, and to stick and work hard. The edges of the cups, also, when made thin, break or wear rapidly. Sheet metal only has thus far been successfully employed in meta-l molds, and when made thin its edges are very easily bent or dented, and thus injuring their efficiency. The swellingof the wooden matrices also renders the plungers liable to stick, and the cups are apt to be bent or broken in removing the lid, as the tendency is to raise one end quicker than .the other. Our invention obviates all of these difficulties, as the plungers or matrices are made sufficiently elastic to avoid sticking, while a close fitting of the parts is readily obtained and the sticking of the parts of the mold is obviated.

Another benefit is obtained by the use of elastic material for the cups. The pressure on the bunch has a tendency to expand the cup, causing the edges to expand under pressure and press close against the sides of the matrices, which makes a smoother bunch, lessening the tendency to crease the same.

In the accompanying drawings, Figure 1 represents a rubber cup without the usual flanges. Fig. 2 represents a series of flanged cups attached to the lid, partly detached from the series of matrices. Fig. 3 represents a series of cups-attached to the lid and resting in a series of matrices. Fig. 4 represents an elastic lining for one of the matrices. Fig. 5 represents several matrices lined with rubber, with the cups attached to the lid resting therein. Fig. 6 shows theaction of the cups on the elastic lining in the act of raising the lid.

A represents the bottom of the mold; B, a series of matrices in which the tobacco bunches are placed for shaping. 0 represents a series of rubber or elastic plungers attached to a backing. c 0 represent ordinary flanges made on the cup.

The elastic cups can be made of the form shown in either Figs. 1 or 2, and the cups 5 to side strains, as shown by the left-hand cup in Fig. 2, when the lid is raised in the manner there shown. The cup may be made of rubber, gutta-percha, or celluloid, and must be molded of the proper shape and then attached to a backing.

D represents the elastic lining for the matrices, and they may be secured in position by means of cement or otherwise. This lining can be made of material much more elastic than the cups 0, in which case wooden or metal cups can be used therewith. These linings are molded of the proper form and then attached within the matrices, as shown in Fig. 5, by cement or other mode of fastening.

\Ve claim 1. A cigar-mold lid provided with invertedcup-shaped plungcrs which are made of elastic material and adapted to be employed in connection with the ordinary matrices, substantially as herein set forth.

2. An inverted cup shaped plunger for a cigar-mold, made of india-rubber or other suitable elastic material, substantially as herein set forth.

3. .A cigar-mold having a series of matrices made in wood or other suitable rigid material and lined with a thin elastic lining, substantially as herein set forth.

4. The combination of a cigar-mold lid having a series of elastic inverted cup shaped plungers attached to a rigid backing with a matrix-block the cavities of which are lined with thin elastic material, substantially as herein set forth.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
