SPECIFICATION forming part of Letters Patent No. 603,231, dated April 26, 1898.

' Application filed June 30, 1897. Serial No. 643,973. (No model.)

To all whom it may concern:

Be it known that I, JAMES CORNELIUS, of Ridgewood, in the county of Bergen and State of New Jersey, have invented a new and Improved Tablet-Machine, of which the follow-' ing is a full, clear, and exact description.

The object of the invention is to provide a new and improved tablet-machine which is simple and durable in construction, very effective in operation, and arranged forready adjustment to produce tablets of any desired shape and thickness and to conveniently dis charge the finished product from the forcingdie of the plunger.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts .in all the figures.

Figure 1 is a side elevation of the improvement. Fig. 2 is a like View of the same with parts in a different position. Fig. 3 is a front elevation of the same. Fig. 4 is a sectional plan view of part of the improvement on the line 4 4 of Fig. 3. Fig. 5 is a transverse section of the improvement, and Fig. 6 is a sectional plan view of part of the improvement on the line 6 6 ofFig. 3.

The improved tablet-machine is provided with a base A, supporting a post or standard A, carrying a table B, open at the front and adapted to contain the material to be formed into the tablet. j In the table B is formed an opening for the reception of the dieO, held in place inthe table by a set-screw O, engaging an annular recess in the die,'the latter being flush with the top surface of the table," as plainly indicated in Fig. 5. The die is provided with a central bore, which may be ofany desired shape, it being understood that dies with .various. forms of bores may be insertedin the table B and fastened therein by the'set-screw O to form tablets of various shapes. Into the bore of the die 0 is adapted to pass theupper end of an anvil D, forming abottom for the die-bore to hold the material in the bore during the time it is compressed, as hereinafter more fully described.

- The anvilD is fitted to slide vertically in a suitable bearing A projecting from the standard A and containing a friction-washer D, engaging the anvil to hold the latter in position unless forced up or down, as hereinafter described. The lower end of the anvil D is adapted to rest on the spiral cam-sur face E, formed on top of the cam E, provided with a vertically-disposed central pin E mounted to turn in suitable bearings in the base A. The cam E is provided with an out wardly-extending arm E adapted to be taken hold of by the operator to turn the cam, so as to bring the spiral cam-surface at different points incontact with the under side of the anvil D to raise the latter or to permit the same to move downward, according to the dimotion in which the cam E is turned.

In the arm E is held a set-screw E, adapted to abut against a stop-pin F, removably inserted into one of a series of apertures A formed in the base A in the segment of a circle, the center of which is in the center of the pin E, as will be readily understood by reference to Fig. 4:.

By the arrangement described the forward swinging movement of the handle E is limited by the set-screw E striking against the stop-pin F, and it is evident that more or less turning motion can be given to the cam E by adjusting the stop-pin F correspondingly in the apertures A The handle E preferably projects from the side of the cam at the highest edge thereof, as shown in the drawings, so that when the handle E is turned from the left to the right away from the pin F until the handle E stands at right angles to the base A then the lowest portion ofthe camsurface E is directly under the lower end of the anvil D, as illustrated in Fig. 2, and the j I upper end of the said anvil is now a suitable distance below the lower end of the die Off When the handle E however, is in the for ward position, with the set-screw E abutting against the pin F, the anvil D is in a raised position and extends with its upper end intothe lower portion of the die 0. I

When the anvil is in an uppermost posi tion and forms the bottom for the bore of the die 0, the said remaining portion of the bore is filled with the material for forming the tab let, and'this amount of material is regulated in quantity by the distance that the upper end of the anvil passes into the said die 0. Now as the cam-surface E gages this upward movement of the die and the movement of the cam is limited by the said set-screws E striking the stop-pin F it is evident that by adjusting the stop-pin F in a corresponding aperture and moving the handle forward until the set-screw E strikes the pin the quantity of the material is gaged, and the operator is enabled to regulate the amount at will by the adjustment referred to.

A plunger G is adapted to pass into the die 0 from above to compress the material in the die, and this plunger G is secured by a setscrew G in the stock II, fitted to slide vertically in a suitable bearing A forming part of the standard A. The rear face of the stock H is formed with rack-teeth II, in mesh with a gear-wheel I, mounted to turn in a bore in the standard A, and forming part of a handle I, secured to one outer end of the said gear-wheel. The other end of the gear-wheel is engaged by a washer I to prevent the lateral displacement of the gear-wheel in its bearing. On the hub of the handle I is formed a cam-surface 1 adapted to engage the upper end of a rod J, fitted to slide loosely in the bearing A forming part of the standard A. A spring J presses the said rod J, so as to hold the same normally in an uppermost position. The lower end of the rod J is pivotally connected with an arm K of a bell-crank lever mounted to turn on a pin K, secured to the bearing A previously referred to. The other arm K of the bell-crank lever extends upwardly and is provided with a pusherarm K adapted to rest against the rear of the anvil D when the latter is in an uppermost position and to pass over the said anvil when the latter is in a lowermost position to push the tablet carried onthe upper end of the said anvil off the same, so that the tablet is discharged from the machine.

The operation is as follows: Vhen the several parts are in the position illustrated in Fig. 1, the anvil D is in an uppermost position that is, it extends into the die C--and the plunger G is likewise in an uppermost position above the table B, so as to permit of filling the die with the material to be formed into the tablet. Vhen this has been done,

the operator swings the handle I over into.

the position shown in Fig. 2, whereby the gear-wheel I is turned and the stock H with: the plunger G is moved downward and the lower end of the said plunger passes intothe die and compresses the material therein against theanvil D, which forms-the bottom for the die. operator takes hold of the handle E and swings the same to the right into the position.

shown; in Fig. 2 to bring; the lowest point of thecam-surface E under the anvil D. As soon; as this has been done the operator presses the handle I still farther downward into a, lowermost forward position, so as to push the formed tablet, together with the an- XVhen this has been done, thevil D, downward until the tablet is out of the die below the table B, as shown in Fig. 5, it being understood that the anvil D slides downward in its bearing A and is finally held therein by the friction-washer when the handle I is in its lowermost forward position.

3 Vhen this has been done, the operator swings the handle I back to its former position and :in doing so brings the cam-face I over the upper end of the rod J, so that the spring J thereof now forces the rod J upward, whereby a swinging motion is given to the bell-crank lever and the pusher-arm K thereof moves forward to push the tablet oif from the upper end of the anvil D. It then immediately recedes back to its former position, as the camface I passes off the upper end of the rod J previous to the arm I reaching its final position, as shown in Fig. 1. The operator now again takes hold of the handle E and turns the cam E back to its former position-that is, until the set-screw E strikes the stop F, so that the anvil D is raised into its uppermost position. The above-described operation is then repeatedthat is, the die is again filled with the material and the arm I is swung forward to compress the material so as to form the tablet.

It will be seen that by the arrangement described the operator is enabled to readily adjust the anvil D in the die, according to the amount of material desired to be pressed into the tablet, and the operator is also enabled to readily exchange the die, anvil, and plunger for other difierent shapes whenever desired.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1.
