Be it-known that I, FREDERICK A. HUBEL, of Detroit,in the county of Wayne and State of Michigan, have invented an Improvement in Machines for Cutting ofl' Gelatine Capsules,

of which the following is .a specification.

The nature of my invention is that of a new and useful machine for cuttingofl' at are quired and uniform length empty gelatine capsules preparatory to their being removed from the molds upon which they are formed; and I do hereby declare that the followingis a full description thereof, reference being had to the. accompanying drawings and the letters of reference marked thereon, making part of this specification.

I after the crank 0, Fig. 1, hasbeen'turned half around. Fig. 3 is a vertical cross-section on the line w m, Fig. 1. Fig. 4 is. a' plan view of the set of molds. Fig. 5is a plan view of the upper plate of the machine, showingthe cogwheels in their position. Fig. 6 is an enlarged view of one of the cutters and molds, showing the capsule cut Oil and prepared for removal from the mold.

Like letters refer to like parts in each figure;

In the accompanying drawings, which form a part of this specification, A representsa suitable frame resting upon the base E,to support the operating parts of my machine.

D is a platform supported upon the upper end of the rack-bar F, andhas a vertical motion by means of the pinion T engaging with the said rack-bar and operated by the lever H. By means of the segment J and set-screw 9 this platform is secured at any desired elevation. To this platform, so that it will have a vertical motion with it, is secured the arm K,,carrying the hollow arm L, and the screw N, operated by the crank S, so arranged that ,the mold-carrying plate R C may be either unlocked, and therefore withdrawn at pleasure, or may be advanced to and secured in any position. v

The capsule-molds e e are made of metal, and are'secured in a vertical position and at regui, let into proper recesses in the plate B, so as to give the mold-plate a'smooth base.

The arm L is provided with a projection, u, so arranged that it may be turned down toallow the mold-plate R G to beinserted, and then turned up and'pressed against-the edges of said plate, locking the same in position.

In the top of the frame there is'jourualed a series of small drums, b. To eachof these drums is secured a pinion, b, arranged to engage with each other, as shown in Fig. 5. Those in the center engage with a pinion, a, which receivesmotion from the crank O, and communicates such motion, by the engaging pinions, to the drums b. The latter should correspond in number to the number of molds employed on: the mold-plate, and 'must be placed with like regular intervals between them. To the lower sideof each of these drums there is secured,by the screws Z,a downwardlyprojecting s ring -arm, carrying at its free end a knife, secured toIi-the head 0. the machine is in use, the arm, as shown in Fig. 3, will operate the cutter in the position shown in Fig. 6.

- In practice, the molds e, secured, as described, substantially to the plates B G, are withdrawn from the frame after turning down the projection u, thereby'unlocking them, and they are then immersed to the proper depth in the gelatine prepared for the purpose. After the molds have received a coating of gelatine of suflicie'nt thickness to make. the capsules, the mold-plates are placed on the platform D in such a'position that each of the molds is presented to the spaces between the cutters. Then these molds are raised to the'required height within the spaces between the knives, such height bringing the knives opposite the Then the crank S is rotated, forcing the projection it (which has previously been turned up) against the mold-plate, pressing the molds against the'knives, as shown in Figs. 1 and 6. Then the crank O is rotated, which, by the devices h ereinbefore described, causes the knives to perform their ofli-ce, as shown in the latter figure. After the cut has been made, the molds are again raised farther up by the lever H, and the part of the capsule or coating e,

Fig. 6, is shoved away from the upper part, c, Fig. 6. i By the means described it will be seen that Iain able to produce capsulesof uniform length,

5 as may be required, without changing any of the parts'of my machine.

I do not claim the molds by which the cap I sules are made, and upon which they are placed during the Operation of cutting them 011', as described, as part of my invent-ion; nor do I claim as part of my invention the composition of gelatinein which the molds are dipped to form the capsules. I do not claim, broadly, any mold-plate having a series of capsule-molds, as dishes so 'arranged and plates with a handle at the back have been previously described as used simply for molding certain forms of capsules; but

I only claim a mold-plate having the molds secured thereto at regular intervals, when the same is used in combination with the frame of an organized capsule-cutting machine, so as to be held therein and removable therefrom; but

to secure byLetters Patent, is-

1. In a machine for cutting 01f. capsules, the combination of the series of molds e and the rack, pinion, and 'lever F TH, or their equiva- 0 lents, substantially as and for the purposes described.

What I do claim as my invention, and desire 2. In a machine for cutting oif capsules,the combination of the mold-plate,adapted to and holding a series of molds, and the screw mechanism L K N, substantially as and for the purj poses described.

3. In a capsule-cutting machine, a series of knives operated by a crank and pinion acting upon a series of pinions, one of which operates each of said knives, substantially as described.

4. In a capsule-cutti|ig machine, the knives operated by gearing, substantially as described, and supported upon spring-arms,substantially as and for the purposes set forth.

5. In a capsule-cutting machine, the combination of the mold plates provided with molds, rack, pinion, and lever FT H, and the screw mechanism L K N, substantially as and for the purposes described.

6. The removable mold-plate bearing aseries of capsule-molds securedtheretoat regular intervals, combined with andarranged to be held by and withdrawn from the support ing-frame, and when used as and for the purposes set forth.
