IMPROVED PILL-MAKING MACHINE.

The Schedule referred to in these Letters Patent and max-mg part of the same.

To all whom it may concern:

Be it known that I, THOMAS BUSHJBY, of Manchester, in England, have invented anew and improved Pill- Making Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in'thc art .to make and use the same, reference being bad to the accompanying drawings, forming part of this specification, in which- Figure' l is aside view,

Figure 2 is a plan view,

Figure 3 isa side sectional view, and I Figure 4 is a hunt view of my improved pill-making machine.

Similar letters of reference indicate correspondingparts. i This invention consists in constructing a machine, to which the mass orssubstance from-which the pills are to be made is supplied, in the form of a layer or sheet of the properthickness,-and placed upon a table forming part oi'such machine, and, by self-acting mechanism hereinafter described, made to advancebeneath a verticabreciprocating knife, which cuts such sheet into strips or bars of the right width to be formed into pills. These bars or strips immediately fall down between as'tationary segmental-grooved plate and a grooved rcvolving roller. 1 The grooves of such stationary segmental plate and revolving roller being immediately opposite and in close contact with one another, and being of an exactly semicircular shape, together form a series of perfectly parallel circular grooves, so that immediately the strips or bars fall, they are caught by the-revolving grooved roller, and out into pieces of the proper size, which, in passing and being rolled between the groovc of the roller and stationary segmental plate, are shaped into pills.

A represents the frame-work of the machine, consisting of two sides bolted together, and supporting between them the table B, and forming bearings for the shaft 0.

Two housings, D D, rise from the top of such framework, to serve as g'u-ides for the reciprocating knife E, which is connected to and actuated direct from the shaft 0, by means of eccentrics F and connecting-rods G Working upon the pins or studs H, projecting from the ends of such reciprocating knife.

1 is a roller keyed upon the shaft 0, having a series of annular semicircular grooves, K, formed round it, which are arranged as close together as possible, and brought to a feather-edge, as illustrated.

L is a segmental metallic plate, secured, at either side, to the inner sides of the frame-work, and such segmental plate forms a shell'or covering-tor a portion of the roller, and is constructed with a similar number of semicircular grooves to the roller, which grooves are opposite to and in close contact with one another.

M'is a feeding-bar, secured to and actuated by the rocking levers N ,mounted on the outer sides of the frame-work, in swivels O, m which they are also arranged to slide backward and forward.

- The other ends of such rocking -le\'eis have howls, P, mounted upon studs projecting from two segmental arms, which bowls rest upon cams, Q, keyed to the shaft 0. r,

Projections, R, shown in dotted lines in fig. l, are formed at. the back of each of such lovers, which are raised by the cams S during a certain portion of the revolution of the shaftG, upon which such cams are also keyed.

T is a spring impinging upon thc top of the locking levers N, to keep them down on to the cams.

U is a stripper aflixed across the roller I, to remove any pillswhich may stick to it while revolving, aud

V is a winch-handle for actuating the machine.

The manner of making pills by this inach inin'ay be thus described:

The mass from which the pills are to be made is placed upon the table B, and motion being .conn'nunicated to the machine by'the winch-handle V, the feeding-bar M immediately draws them-ass forward beneath the reciprocating knife 15, which cuts off a strip orbar of the right width. .Meanwhilc the cams S, coming in contact withthe projections B, have caused the feeding-bar M to rise and disengage itself from the mass, when the cams Q, by. impinging against the bowls P, cause such iecding-bar to rccede in order to take a fresh gripe of the mass, the strip or bar cut-oil by the reciprocating knife havingfallcn between the segmental-grooved plate L and the revolving grooved roller 1, is out into small pieces, which, in passing and being rolled between the stationary grooves of the segmental plate L and thercvolving grooves ofthe roller I, are shaped intopclfcctly spherical pills, which fall out at the bottom of the segmental-grooved plate L,

and if any pills stick to the roller, they are instantly removed by the stripper-plate U.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patentl. The combination, with the grooved roller I, of the segmental-grooved plate L,- substantially as and for the purpose described.

2. The combinationof the grooved rollers, segmental plate, and the reciprocating knife, substantially asand for the purpose described.

3. The feeding-mechanism, constructed as described, in combination with a pill-forming mechanism, substantially as and for the purpose set forth.

The above specification of my invention signed by me, this 7th day of April, 1868.

' THOMAS BUSHBY.
