IMPROVEMENT IN CIGAR-lvioLDs.

Specification forming part of Letters Patent No. 175,573, dated April 4, 1876 application filed January 19, 1876.

To alt whom it may concern Be it known that I, FREDERICK G. MILLER, of Cincinnati, in the county ot' Hamilton and State of Ohio, have invented a certain Improvement in Cigar-Molds, of which the following is a specification This invention relates to cigar-molds adapted for pressing a number of bunches of tobacco into cigar shape, the bunches being placed in deep matrices, and simultaneously pressed into the required form by the operation of a series 0t` plungers or cups.

My improvement consists, first, yin so constructing the plungers or cups, which are made of wood like the rest of the mold, that the grain of the wood shall run verticallythat is, at right angles to the face ot' the backing to which the plunger-s are attached. This enables me to .obtain not only durable but also sharp edges along the sides ot' the concaved face of the plungers, which sharp edges are ot' the utmost importance to the proper action of the mold, and which, it formed on plimgers having the grain of the wood running longitudinally, in accordance with the common method ot' construction, do not possess the requisite strength and durability; second, oi' a peculiar method ofsecurin g the plun gers or cups to their backing, whereby a strong attachment and a perfect register with the matrices is obtained. This method consists in making the matrices somewhat deeper than required; then gluing the backing to the face of the matrix-board; then sawing the block thus formed into two parts on a line a little below the top of the matrix-board, so that a thin strip of it will remain attached to the backing for the plungers; and, iinally, inserting the plungers or cups in-the cavities in this thin strip ot' the matrix-board adhering` to their backing, and securing them in proper manner; third, in the combination, with the matrix-board, of one or more bars for eX- pelling the bunches after they have been pressed. The bar is seated in a longitudinal groove across the matrices, its upperedge having notches corresponding to the cross-seotional contour of the Ina-trices.

In the annexed drawings, Figure l is a perspective view of the two sections of the mold separated from each other. Fig. 2 is a longitudinal section, showingthe pliingers lifted from ofi' the matrixiboard, and the expellerbar in its raised position. Figs. 3 and al. are detail views hereinafter more 'particularly referred to.

The saine letters of reference are used in all the figures in the designation of identical parts.

The matrix board or block consists of two boards, A and A', the grain of the one marked A ruiming longitudinally,While that of the other, in which the matrices a are formed, runs transversely-that is, in the direction ot' the length of the matrices. These boards are glued together. Plugs al, having the grain running vertically, are used at the narrow enti of the matrices to strengthen the mold at these points. The eXpeller-bar B is placed in a groove across the matrices, ektending from one end of the board to the other. Its upper edge is notched, so that when it is pressed home to its seat the notches will register pert'ectly with the matrices. Near each end the bar is reduced in width sufficiently to permit it tobe raised to the extent required for expelling the bunches before the reduced ends b strike the bridges b placed across the groove in which the expeller is seated. The bridges, being' staples driven through the upper into the lower board, also serve to strengthen the mold. In the present instance the ends ot' the expeller are exposed for manipulation. This is not material, as it may be reached through a hole or holes from underneath.

To facilitate the operation of the expeller, it may be made slightly tapering from top to bottom, the groove in which it is seated being tapered correspondingly. At the mid-length of the matrix-board an exceptionally wide space is lct't between the adjacent matrices,

and a way, a2, with an inclined bottom cnt j across it, which way is intended to receive a wedge, C, to be used for separating the male halt' ot' the mold from the matrix-board or female half.

Instead of a single inclined way at the cen-J ter, one such way may be provided at each end, and the wayinay be formed in the male halt instead ot'in the female halt'ot the mold.

The bridges b hug the oisets on the expeller, and thus guide it as well as prevent it from moving endwise.

The male half of the mold is constructed in the following manner: The backing D, which has the grain of the wood run lengthwise, is glued upon the top of the matrix-board, the matrices in which are cut deeper than required, as shown in Fig. 3. The block is then sawed in two along the line fr, Fig. 3, so that a thin strip, D', of the matrix-board will remain attached to the backing D. The cups or plungers E are then glued to the backing D Within the recesses in the strip D', so that said plungers will register perfectly With the matrices, and also receive a rm support along their sides.l VA Wide space is left unoccupied at the center of the male part of the mold, the same as in the female part, to provide for the operation ofthe separating Wedge. The cups or plungers E are made of Wood, the grain of which runs verticallythat is, at right angles to the plane of their back surface. Their i edges c can, by reason of this disposition of the grain of the wood, be made very sharp. This is a very important consideration, for the sharper these edges the less is the liability of. leaving creases on the bunches, which is a decided objection. The edges e, although made n sharper than they can be used on cups in which the grain of the Wood runs longitudinally, are, notwithstanding, much more durable.

This mode of constructing' the cups is applicable, of course, to molds other than the particular kind described. Y

DoWel-pins F serve, as usual, to guide the male half in applying it to the female half.

What I claim asv my invention, and desire to secure by Letters Patent, is-

1. The plunger or cup of a cigar-mold made of Wood, the grain of which runs perpendicularly to the plane of the cup, substantially as specified.

2. The male part of the cigar-mold, composed of the backing, the adhering strip D', and the cups or plungers set in the cavities of said adhering strip, substantially as specified.

3. The combination, substantially as specifled, of the matrix-board, and the expeller-bar seated in a groove transversely to the matrices. 7 y
