IMPROVEMENT IN PILL-MAKING MACHINES.

Specification forming part of Letters Patent No. [4,l6l. dated June 29, 1856.

To all whom it may concern:

Be it known. that I, NOAH W. KUMLER, of the city of Cincinnati, in the county of Hamilton and State of Ohio, have-invented a new and useful Improvement in a Machine for Makiug Pills; and I do hereby declare that the following is a full andfexact description-thereof, reference being had to the accompanying drawings, forming part of this specification, and to the letters and figures of reference -marked thereon, similar letters and figures referring to correspondingparts of the improvement.

- The nature of my improvement consistsin placing plates of wood or metal the required distance'apart, and have all or part of them adjustable by means of set-screws, or otherwise, and witha pulley'and belt draw the pill material between said plates'and roll it out to any required size in the shape of round bars, after which it is conducted to arevolving metal roller provided with semicircular groovescut around its circumference, and the bars of pill material are carried between the face of said roller and a segmental plate of metal furnished with semicircular grooves similar to those on the. face of the roller, and the projections formed by the grooves on the roller andsegmental plate cut the bars of pill material into the required sizes, when they are rolledaround bythe motion given to the roller until formed into balls. suitable for use, after which they are discharged from the machine; ready for packing.

To enable othersskilled in the art to make and use my improvement, I will proceed 'to describe its construction and operation, by referring to the. accompanying drawings, of which-.- A

FigureA represents a longitudinal sectional elevation of the improved machine, showing the manner of placing the pill material in the machine and the manner of rolling and forming thesame into pills. Fig. B represents a top view of the machine. Fig. 0 represents the grooved roller drawn separate, in combination with a sectional view of the segmental grooved plate. Fig. D represents a front elevation of the machine.

1 represents the pulley, provided with acrank, 21, and belt or apron 2 2, which runs around the drum 3 at the rear end of the machine. The said drum revolves in the levers roller.

28 28, for the purpose of tightening the belt, by forcing the drum out with the set-screws 27 27 on each side of the machine, as shown 17 between the grooved roller-12 and segmental plate 14, where it is cut, as before stated, into the proper-sized pieces and rolled into balls.

and finally discharged from the machine at the lower part of the segmentalplates 14; on the discharging-plate19, as represented in Fig. A.

The roller 12 receives its motionthrough the gear-wheels 16 16, one of which is placed on the axis of the pulley l, and the other on the The pulley and roller. revolve in the frame 6 6, and 11 represents the rear portion of the frame to which theplates and drum 3 are attached.

9 9 represent adjusting-screws working-in the cross-bars 22 22, for the purpose of adj ust; i ng the plate 7 7 to'and from the belt 2, and

10 10 are similar screws for adjusting the plate 8 8. The plates 4 and 5 are made stationary by attaching them to the frame-piecesd and 11.

18 is what I denominatea powder-box, which receives a vibratory vertical motion by means-of the levers 25 25, which are attached to the said box and work'on pivots screwedin the frame, said leversreceiving their motion by the cam form of the axis of the shaft, as seen at 26 in Fig. A, at the center of the pulley. The object of this arrangement is to jar some.

suitable powder downthe couducting'plate 29 upon the roller 12, to preventthe pill material from adhereing to the roller and segmental plate 14:, and also serves to give a coating to the. ills.

20 20 represent rods made to pass through the framing 6 6 and flanges 15 15, for the pur-- pose of holding thegrooved segmental plate 14 v at the proper relative distance fromv the roller 12. Said flanges are part of the-segmental plate.

p '13 13, in Fig. 0, represent the'groorescut in the roller, and-14 a. sectional view'of the segmental plate,.which shows the manner of forming the pill when they are brought together, giving it a. true spherical shape.

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

The combination of the adjustable plates 7 and 8, apron 2, pulleyl, and drum 3, and these in ombination with the grooved roller 12 and segmental plate 14, all substantially as and for the purposes set forth in the foregoing speei- .fication, and represented iii the accompanying drawings.
