IMPROVEMENT IN MACHINES FOR CUTTING OFF GELATINE CAPSULES.

Specification forming part of'Lctters Patent lq'o. 187,279, dated February 13, 1877 Reissue No. 8.440, dated October 1, 1878 application filed August 17, 1878.

in Machinesfor Guttin g Ofl' Gelatine Capsules,

of which the followingis a specification The nature of my invention relates to certain new and useful improvements in machines employed to cut ofl at any required and uniforni length empty gelatine capsules, preparatory to their removal from the molds upon which they are formed.

The invention consists in the peculiar construc'tion, arrangement, and operation of the various parts, as v more fully hereinafter described.

Figure 1 is a front elevation of my improved machine. Fig. 2 is a plan view of the upper plate, showing the knives in their position after the crank 0, Fig. 1, has been turned halt round. Fig. 3 is a vertical cross-section on the line .r :r, Fig. 1. Fig. 4 is a planvicw of a set'of molds. Fig.5 is aplan view of the upper plate of the machine, showing the cog-' wheels in their position. Fig. 6 is an enlarged view of one of the cutters and molds, showing the capsule cut off 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 represents a suitable frame, resting upon the base E, to support the operating parts of my improved machine. D is a platform, supported upon the upper end of the rack-bar F, and has a vertical motion by means of the pinion T engaging with said rack-bar, and operated by the lever H. By means of the segment J and setscrew 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 thecrank S, so arranged that the screw will withdraw or advance the mold-carrying slides 1t 0. The capsule-molds 12 are secured Ill a vertical position and at regular intervals to the top of the plate or slide 0 by nuts 0', let into proper recesses in the plate or slide R. The arm L is provided with a projection, n, so arranged that it may be turned down to allow the plates R O to be inserted and then turned up to rest against the edges of said plates.

In the top of the frame there is journaled a series of small drums, b. To each of these drums is secured a pinion, 1), arranged to engage with each other, as shown'in Fig.5, those in the center engaging with the pinion a, which receives motion from the crank 0, and com municatin-g such motion by the engaging-pinions to the drums b. The latter should correspond in number to the number of molds employed on-the plates R O, and must be placed with like regular intervals between them. To the lower side of each of these drums there is secured, by the screw 1, a downwardly projecting spring-arm, a, carrying at its free end a cutter-head, c, to which is secured a 1'0- tary or circular-shaped cutter, d. The object in view in using a spring-arm is that such spring-arm, set as shown in Fig. 3, when not in use, will compel the cutter to operate as shown in Fig. 6.

In practice, the molds c, secured, as described, substantially, to the plates R(J,are withdrawn from the frame byturning down the projection a, and they are then immersed to the proper depth in the gelatine prepared for the purpose. After the molds have received a coating of the .gelatine of suflicient thickness to make the capsules the slides R O are placed on the plat-- form D in such 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 cutters, such height bringing the cutters opposite the point where the capsules are to be cut 011. Then the crank S is rotated, forcing the projection it against the plates R G and pressing the molds against the cutters, as shown in Figs. 1 and 6. Then the crank O is rotated, which, by the devices hercinbefore described, causes the cutters to perform their oflice, as shown in the latter-figure. After the out has been made,

and while the motion of the cutters is stillcontinned, the molds are again forced upward, and by this operation the tag or cut-ofl' portion e is forced away from the capsule 0'.

By the means described it will be seen that, I am able to produce capsules of uniform length, varying such length as may be required without changing'any of the parts of my machine.

I do not claim the mold e, upon which the,

capsules are formed, nor do I claimthe compositionof the gelatine of which they are made, as these form no part of my invention; but

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

1. In a machine for cutting off capsules, the combination of the series of molds e and the rack, pinion, and lever F T H, for the purpose of regulating the length of the capsules, substantially as described.

- 2. In a machine for cutting oli' capsules, the

combination of the sliding plate, adapted to hold the series of molds, and the screw mechanism L K N, for the purpose of forcing the -molds against the knives, substantially as described.

3. In a capsule-cutting machine, a series of rotary cutters operated by acranl; and pinion acting upon pinions, one of which is attached to each of said cutters, substantially as specifled.

4. In a capsule-cutting machine, the rotary cutters, driven by gearing, substantially as'de-.

scribed, and supported upon spring-arms,snl stantially as and for the purposes-set forth.

5. In a machine for cutting off capsules, the combination of the sliding plates, adapted to hold the molds of the rack, pinion, and lever F '1 H, and the screw mechanism K L N, for the purpose of giving both a lateral and vertical motion to the sliding plates, substantially as described.

6. The plate R C, in combination with a series of capsule-molds secured thereto at regular intervals, substantially as and for the purposes set forth.
