MACHINE FOR CUTTING OFF CAPSULES. v

SPECIFICATION forming part of Letters Patent No. 255,829, dated April 4, 1882.

Application filed January 23, 1882. (No model.)

To all whom it may concern:

Beitknown that we,LOU1s J. WOHNLICH and RICHARD J. ScHoLEs, of Detroit, county of to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it-pertains to make and use'it, reference being bad to the accompanying drawings, which form a part of this specification.

Ourinvention consists in the combinations of devices and appliances hereinafter specified,

and more particularly pointed out in the claims.

In the drawings, Figure 1 is a front elevation of a machine embodying our invention. Fig.2 is a plan view of the platform which supports the mold-table, showing the means for clamping the table to the platform. Fig. 3 is aplan view of the platform which supports the drums at the uppe'r'ends of the rotary cutters. Fig.4 shows separate sectional views of the springdrum and chain mechanism,'together with the rotary cutters.

The objectofourinvention is to facilitate the cutting of gelatine capsules upon the molds upon which they are formed.

To this end A represents the frame supporting the device.

Bisavertically-movableplatform,supporting a mold plate or table, B, of capsule-molds b, with the capsules 1) formed thereon.

B is a sleeve arrangement fitting upon the sides of the frame A. I 1

O is a screw; 0, a rotary nut; (1 a beveled wheel geared into the nut.

O is a shank, and G the handle for turning the same and elevating or lowering the table.

I) is a spring catch or pawl in the handle 0*.

b is a segmental rack-bar, into whichthe pawl b may engage at any desired point to hold the table B in any desired position.

B are clamps, operated by a lever, B for holding the mold-plate B firmly inposition upon the table. The plate is guided to its proper place by cleats B D D represent beds or plateshaving a down: ward and upward movement upon or within the frame A.

d is a spring attached to the interior of the case 0 coiling about the shaft 0.

d is a chain secured at one end to the outer surface of each drum and coiled once around the drum as it stands'iu its normal position, the other end being attached to pins d on a sliding bar, F. e

F is a lever attached to lheframe above, by which the sliding bar F is moved longitudinally. When the lever, with the sliding bar attached, is pulled outward from the machine the spring in the drum is coiled,and by letting go the lever the springs uncoil and the chain is coiled about the drum. Theshaftofthe spring and drum thus makes one or more revolutions with the crank attachment 0 and with it the spring-arm E, pressing the rotary cutter E about the capsule upon the mold.

G G are cog-wheels pivoted upon hangers depending from the top piece of frame A and gearing with an intermediate cog-wheel, g, journaled upon a hanger and provided with a crank, G.

G G2 are links, having their upper ends pivoted upon crank-pins projecting from the hubs or near the centers of wheels Gr Gr and their lower ends pivoted to ears projecting from the plate'D. When the crank G is turned and motion communicated to wheels G the plates D and D have an up-and-down or jigging motion communicated to them through the links G2 and springs D so that the rotary cutters E will be caused to scrape loose the waste portions of the capsules below the circular incis ions made by said cutters and said waste portions will fall from the molds.

- By the operation of this device the capsules can be cut uniformly at any required length and the severed portion separated from the capsule. c is a spring-case loosely connected with the drum-shaft. One end of the spring is connected to this case and the other end to the shaft. 0 is a pin or screw, by which the springcase may be secured immovably after it shall have been turned sufficiently to give the desired tension to the spring.

In using the machine the plate B detached is inverted and the molds dipped in properlyprepared gelatine in the usualmanuer,and after the molds have received a coating of sufficient thickness the plate Bis placed upon the platform B,as shown in the drawings, and secured by the clamps B which are operated by the lever B and connecting-links in an obvious manner. The platform B is then elevated to bring the molds in proper relation to the rotary cutters E, this being performed by turning the crank O and the bevel-gear C first disengaging the pawl b from He rack D The wheel 0 gives a rotary motion to the nut O, which drives the screw 0 upward to raise the platform to the desired position, where it may be retained by allowing the pawl b tore-engage with the rack If. The lever F is then operated to move the sliding bar F and cause the operation of the cutters, as before described, after which the crank G is turned to cause the cutter to scrape 011' the waste portion of the shell, and the moldplate may then be removed and the platform lowered for another operation.

We are aware that acapsule-cutting machine has heretofore been in ventedin which the moldplate is placed upon a vertically-moving platform and by it raised to bring the molds in proper relation to rotary cutters carried by spring-arms, and that in such a machine the waste is removed from the molds by forcing them upward after the capsules are cutoff; and we do not claim such a machine broadly.

What we claim is- 1. In a capsule-cutting machine, a series of rotary cutters mounted on spring-arms dependin g from vertical rotary shafts provided with drums driven in one direction bytheuncoiling of chains or bands, and retracted by springs, substantially as described. 7

2. The combination, with the series of drums fixed upon the cutter-shafts, of the bands, each having one end attached to the outside ofone of the drums, one or more slides connected with the opposite ends of said bands,and means for operating said slides, the whole being arranged to operate essentially as set forth.

3. The combination, with the rotary shaft and drum to which any cutter is attached, of a spring, one end of which engages the shaft and the other end' is attached to an adjustable drum-case, and pins or screws by which said drum-case may be given any desired rotary adjustment for varying the tension of the spring, substantially as described.

4. Thecombinatiomwith a platform supportingtherotaryeutters,ofone ormoresupportingarms, connected at their upper ends eccentri-- cally with corresponding pinions, and a crank and pinion for rotatingthe same and imparting a jigging motion to the cutters, substantially as described.

5. In a capsule-machine, the combination, with the mold-plate-supportingplatform,ofthe two clamps B B, the lever B, and connect? ing-links, whereby said clamps are operated simultaneously, substantially as described.

6. In a capsule-cutting machine, the combination, with the rotary cutter supportingplatform, and jigging mechanism, of springs located beneath the platform, serving as cushions, substantially as and for the purposes described. In testimony whereof we sign this specifica tion in the presence of two witnesses.
