ONE-HALF MOLD Fon MAKING PLUG-TOBACCO.

SPECIFICATION forming part of Letters Patent No. 773,008, dated October 25, 1904. Application led September 17,1903.` Serial Nol 173,547. (No model.)

To ctZZ lah/0111,. t may concern:

Be it known that I, RICHARD E. ELLIS, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga, in the into plug shape cigar-cuttings, scrap-tobaccos, and also leaf-tobacco with or without said cuttings and scraps and without requiring the tobacco tobe put up iii-separate bundles ofpredetermined size or weight before applying the tobacco tothe mold; and to that end the-invention consists in the novel construction and combination of a mold-frame provid ed with vertical knives extending across the interior of said frame and disposed with their cutting edges at their tops and Ya follower of the same perimeter 'as the interior of the said mold-frame'and entering the same andl provided with creases coinciding with the aforesaid knives and extending' part way the depth of the follower to meet the integral top portion thereof, and thereby cut the tobaccov throughout the depth of the layer, all as hereinafter more fully described and as summed up in the claim.

In the annexeddrawings, Figure l is an elevation, partly in section, showing the operation of molding and compressing the tobacco as aforesaid. Fig. 2 is a transverse section illustrating the mold charged withthe tobacco to be compressed therein. Fig. 3 is a plan view of the mold, and Fig. 4 is a perspective view of the attaching end of one of the knives.

Similar letters of reference indicate corresponding parts.

A represents the mold-frame, which is provided with two series of vertical knives t c', disposed at right angles to each other and exy tending across the interior of said frame and i secured thereto in any suitable manner, pref; erably by means of tongues Z, projecting from the ends of the knives and inserted into grooves cin the inner sides of the frame and extending from the bottom of the frame part way toward the top, as shown in Fig. t of the drawings. The knives of one series are provided with vertical grooves Z (Z, into which 55 are inserted the knives of the other series. Each of the knives is disposed with its cutting edge upward, as shown in Fig. 1 and Fig. 2 ofthe drawings.

B represents a horizontal press-bed upon 6 which the aforesaid mold-frame is mounted preparatory to molding and pressing the tobacco, which is deposited into the pockets e c, formed between the knives, as shown in Fig. 2ofthe drawings. Theknives extend through 65 the entire depth of the mold-frame and are supported on the press-bed, which forms the bottoms of the pockets c c.

C denotes the follower, which is of the same perimeter as the interior of the mold-frame A, so as to allow it to enterl into said moldframe. This follower is detached from the press-head and provided in its under side with creases Z Z, which coincide with the positions of the knives c a', so as to allow them 75 toenter into said creases. The creases extend only part way the depth of the follower and arev terminated by the integral top portion of the follower.

In the operation of molding and compressing the loose tobacco into plug shape said tobacco is deposited into the mold and partly spreadover the tops of the knives, as shown in Fig, 2 of the drawings. Then the press is operated to force the follower down into the mold. The descent of the follower causes the knives to cut through the overlying tobacco and to meet the integral top portion of l the' follower, as shown in Fig.'l of the drawl ings. This insures a perfect separation of 9o the compressed plugs from each other.

If desired to expedite the process of molding and compressing the tobacco into the shape of plugs, a plurality or tier of mold-frames A, with intervening followers C maybe placed in the press, as represented in Fig. 1 of the drawings. y

To guard against injury to the follower by severe contact thereoil with the edges of the knives, I employ7 suitable stops forlimiting the movement of the follower, which stops may consist of collars ff, adj ustably secured to the press-rods L L and engaging the under sides of plates t' z', which are rigidly attaehed to and project laterally from the presshead P.

I do not limit myself to any special form of the press, inasmuch as there are numerous presses of various constructions adapted for practicing my invent-ion.
