The ends E E ofbarE are provided with I holesE E (see Figs. 5 and 6,) respectively,

. such holes fitting over the verticalstandards B Bin a' inanner to permit vertical 'move-, ment of the bar on the standards. I F F are compression-wheels: rotatabl I mounted on horizontal barE. This bar E is preferably built up (in the in Figs. 5 and 6) of the part e, the rods or. axles e e, and endsE E. The part e is prowhieh thevertiwhich an adjusting bolt, hereinafter de scribed, extends. The axle or rod e extends into the part e and into the part.E in the manner indicated by the dotted lines in F i y secured in place, as, y the rivets e e v The vertical shaft'G may be provided with the ball-bearings g at the lower end th e03 extends through-the horizontal bars D and E we and rotates therein. I V a H is a cylinder on shaft G-.. I I \The shaft G is provided with the; shoulder g thereon, (see Flg. 2,) and the cylinder H is I 1 provided wi-tha hub it, having a hole therein fitting on the smaller part of the vertical 4 shaft G, so thatsuch-cylin'der rests on the shoulder g'-,-as is illustrated in 2 .0% the manner illustrated I drawings. Cylinder H is secured rigidly to the shaft G to turn therewith, as by the feather I. (See Fig. 2.) Cylinder H may be removed from vertical shaft G whenever de- 5 sired by removing the horizontal bars D E from vertical standards B B and removing the feather or spline I from shaft G, and such cylinder may be replaced by another eylinder, (a duplicate thereof,) in which the dies about to be described are of a different size or shape from those on the first-named cylinder.

is an annular flange which may be and preferably integral with cylinder H. h h and k h areannul'ar flanges fitted rigidly onto the c liind-er H. (See Fig. 2.)

' J J, J J and J respectively, are holes in the annular flanges of cylinder H. K K are plungers in holes J J, and K K are lungersin holes J J Pl-ungers K K are ereina-fter referred to as the lower series of plungers-, and plungers K K are here inailter referred to as the u per series of 1;. plungers. In the several p ungersof the ower series there are placed punches L L, and in the severaitilungers of the up er series there are place the dies L L. The severa-l dies are firmly secured in place, as by the set-screws Z Z.

M is a die in one of the holes J J of flange h. 0 m is thehole in die M. (See Fig. 2.)

When the several parts of the machine are all assembled, there is a die M ineach one of the holes J, and a lunger containing a unoh is mounted in eac' set of holes J J an J J 3 5 The lower series of punches L L are set in the lower series of plungers K K, so as to be in the die M (see Fig. 3) when at the lowest possible position of such punches, and the thickness of the tablet compressed by this 40 machine is determined by the position of the upper end of such punches L L when in such lowest possible position, and hence in order to make tablets of different thickness in the machine 1? make the position of theplungers K K adjustable longitudinally, asby means of a thimble N, Figs. 2 and 7, mounted there: on and providedwith screw-threadsn therein. Screw-threads n in the thimble N intermesh with screw-threads n on the plungers K. N is a slot in thimble N. This slot when used is made before the screw-threads n are cut in the thimble, and thereby such screwthreads fit sufficiently close to the plunger K to prevent the same from turning from an adjusted position.

N Fig. 2, is a spring on plunger K. The upper end of spring N abuts against the under side of the upper one of the annular rings k and the lower end of such spring rests on the shoulder n obtained by placing the head a on thimb-le N. The spring bl on plunger K tends to yieldingly hold such plunger down, so that the head a of the thimble N thereon rests on the upper face of the lower 6 5 one of the annular flanges h.

N is aws' ring on plunger K, tending to hold such p unger up-that is, in a retracted position-in the same manner as spring N tends to yieldingly hold the plunger K down in a retracted position.

N is a collar on the plunger K, correspending in function with the thimble N on plunger K, and N is a set-screw by means of which collar N is maintained in an adjusted position. v

The quantity of material deposited in the hole m of the die M is determined, as hereinbefore stated, by the adjustment of plum er K, which is obtained by thimble N', as escribed, and to obtain the movement to plunger K and die L, mounted therein, required to give the density required to the tablet made in such die M, I provide the adjustments and connections between the bars D andE, which I will now describe.

0 O are set bolts or screws extending loosely through bar D and provided with screw-threads O at the lower end thereof, intermashing with corresponding screwthreads in hole 0 of bar E. I

P P are nuts on bolts 0 0, such nuts being provided with threads which intermeshwith threads 0 O, and Q Q are springs on bolts or screws 0 O.

Bar D is secured rigidly on standards B B by means of set-screws l)" D". Adjustingbolts 0 O are then turned and bar E thereby forced down, so that the wheels F F depress the several plungers K K passing thereunder to give the desired thickness to the tablet made in hole m of die M. The bar E is thus yieldingly held in its adjusted position by means of the lock-nuts P P and springs Q Q- that is, the tendency of the bar E to be forced up by the passing of the several plungers K K thereunder in the revolution of the shafts G and cylinder H is opposed by the springs Q Qand it thus occurs that in order to obtain a given density to the tablet made in hole 'm. a determined adjustment of the locknuts P P on bolts(.) 0 relative to the springs Q-Q is required. The more the nuts P P are forced against such springs Q Q the greater is the resistance offered by such springs to any upwardunovement of the horizontal bar E.

R is a thin cylindrical covering-say of sheet metal-over the annular flanges h h and h h, respectively, merely to prevent dust settling on the respective plungers in such flanges.

To force the plungers K K up after a tablet has been made in die M, the wheels S S, Fig. 1, are provided. The several plungers are raised as they are carried over such wheels by the rotation of the cylinder H.

To supply material from which tablets are to be made to the hole 'm, of die M, I provide a hopper T, with pipe U depending there-- from and the extension V at the lower end thereof. Such extension V rests on table 0.

The several dies L L ass over the extension V in the revolution the c .linder H, as is shown in Fi 1, .and the ho e m is filled by the materia contained in hopper T, depending pipe U, and extension V, and when the respective dies M come out from under the extension V they are filled with material which is compressed when the punch L there over is depressed by the plunger in which such punch is held, passing under the adjacent one of the depressing-wheels F F.

In this machine there are made at each revolution of the cylinder H two tablets for each pair of plungers (an upper and a lower one) in the respective annular rings on such cylindcr,;one of such tablets being made as the upper plunger'of apair passes under one of the wheels E E and the other of such tablets made as such plunger passes under the in number of times in therevolution of the cy inder, such mechanism to force the plungers of the upper series down consisting of a orizontal bar vertically movable on the vertical standards, wheels rotatably mounted 'onthe horizontal bar in the path of move-q ment of the upper ends of such plungers, an

additional horizontal bar removably secured on the vertical standards and an adjustable yielding connection'between the horizontal ars substantially as described.

2. The combination of a base, vertical standards on the base, a rotatablymounted vertical shaft provided with a shoulder'thereon, a cylinder provided with annular flanges removably placed on the shaft to rest on the shoulder and to turn with such shaft, an upper and a lower series of Ion tudinally-movable plungers mounted on t e annular flanges,

means to force the 1plungers ofthe-lower series up a plurality 0 times at each revolution of the shaft "and cylinder and mechanism to force the plungers of the upper series down a corresponding number of times in the revolution of the shaft and cylinder, such mechanismto force the plungers of the upper series down'consisting of a horizontal bar vertically movable on the vertical standards wheels rotatably mounted on the horizontal bar in the path of movement of the upper ends of the plungers, an additional horizontal bar removably secured on the vertical standards, and an adjustable yielding connection between the horizontal bars; substantially asdescribed.
