CAPSULE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 275,092, dated April 3, 1883.

v Application filed March 23, 1882. (No model.)

To all whom it may concern:

Be it known that I, HARRIsoN H. TAYLOR, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Capsule-Making Machines; and I do hereby declare that the following is erence being had to the accompanying drawings, which form a part of this specilication.

The nature of my invention relates to cer tain new and useful improvements in that class of machines employed to cut off, at any required and uniform length, emptyggelatine capsules preparatory to their removal from the molds upon which they are formed.

The invention consists in the peculiar construction, arrangement, and combination of the various operatin g parts composing the machine, as more fully hereinafter set forth and claimed.

In order that persons skilled in the art may know how to make and use my invention, I will now proceed to fully describe-the same with reference to the accompanying drawings, in which- Figure lis an elevation of my improved machine; Fig. 2, a plan view taken on the line x a3, Fig. 1; Fig. 3, a bottom plan view of the machine; Fig. et, an-enlarged view in detail, showing the rotating knife and its shaft as in operation; Fig. 5, a perspective view of the cam-head in position for operation; and Fig. 6 is an elevation of the same in the position occupied after-a quarter horizontal turn has been given it.

A represents the bed or base of the machine, made in any suitable form and united by uprights or standards B to a top plate, C, parallel thereto and of a corresponding size. An intermediate plate, E, constructed to have a vertical movement, has its ends sleeved upon the standards B. This plate carries the means employed for cutting off the capsules, said means consisting of a series of small rotary cutters, e, secured by nuts f to the lower ends of a series of downwardly-extending rods or arms c, which pass through a series of flangesockets, b, secured to the plate at regular intervals apart, as shown, the rods c being secured in an adjustable manner within the flangesookets by means of radially-arranged set-screws d. By this arrangement I can readily adjust the arms carrying the cutters to a vertical position, and also elevate or depress them to accommodate any lengths of capsules to be cut. This plate E is operated and limited in its movements by means of a central shaft, F, secured firmly to it at its lower end and extending through' the top plate, G, where it is united to a cam-head, G, being secured theretoby means of a screw-threaded or swivel joint, as shown. This cam-head is provided with a handle, H, for operating it, and should be made of such form and dimensions as when operated it will canse the plateE and the cutters with which it is provided to be depressed the necessary distance to bring the cutters in proper position to allow the cutting of the capsules. In order to lower the plate E to its proper position, the cam-head is thrown over until the handleHassumes the position shown in dotted lines in Fig. 1. Then plate E is in this position the cutters with which it is provided will occupy the place of the upper dotted lines in Figs. l and 4, this being thelimit of the cam movement. When it is desired to drop the cutters to the place of the lower dotted lines in said figures it is accomplished by giving a quarter horizontal turn to the calnhead, thereby allowing its sides to drop into transverse recesses a upon the top piece, C, said recesses being of a proper depth to accomplish the result desired. The object of having the cutters thus arranged, so as to drop a short distance below the position they occupy while the capsules are being out, is to afford a ready means whereby the cutoff ends of the capsules can be pressed away from the capsules immediately after the cutting is done.

To the undexn surface of the base-plate A ot' the machine and at its centeris secured a pinion, I, which is provided with anysuitable device for imparting motion to it. This pinion engages with a group of four pinions, J, arranged aronnd it, as shown in Fig. 3, and secured upon the lower ends, respectively, of a corresponding number of shafts K, suit-ably journaled through the baseplate A. These shafts project above the base-plate a sufficient distance to allow tho circular cranks L to be rco secured to their upper ends. Each one ot those circular cranks is provided with a wristpin, M, adapted to enter suitable openings made in the supporting-plate N, and arranged to correspond in size and position with said wrist-pins, as shown iu Fig. 1, and each wristpin is provided with a swiveled thimble, i, to prevent wear upon the plate. The wrist-pins, upon motion being given to the pinions below, give a horizontal rotary motion to the plate N, said movement being limited by the distance ot' the wrist-pins from the axis of the shafts K. In order to alter the amount of movement of the plate N, the wrist-pins are secured to plates 7L, constructed 4to slide into dovetail or undercut grooves in the face of the cranks L, so that these plates h can be moved to alter the throw ot' the wrist-pins according to the amount ot' movement desired. In order to accurately make this adjustment, l employ a lever, 0, pivoted at one end to the face of one ot' the cranks and provided with a slot to embrace the wrist-pin, the free end of the lever heilig provided with a spring-stop, 7c, to engage with either of a series of notches cut in the periphery of the crank, as shown in Fig. 2. From the'above it will be seen that the movement of the lever 0 will increase or decrease the throw of all of the cranks, and consequently of the plate N also.

I is a plate provided with a series of' roundended pins, R, and removably secured to the plate N by means of theledges S at the edges of said plate. rIhe plate Pis made removable in order that other plates having either larger pins or pins ofthe same size may be put in its place. In practice theplate P is removed,'the ends of its pins are dipped into gelatine to gather a sulIicient thickness ot' gelatine to form the walls and end of the caps'ule, and is again secure-d to the plate N. The camhead G is then thrown over by its handle H, so as to cause the knives to descend to the upper dotted line in Fig. 1, when, rotation being given to the pinions I J, the plate N is moved so as to carry all of its pins or formers bodily around the cutters and all in the same direction, thereby cut-ting oft' the capsules at the proper length. In order to separate the burr from the capsule proper, the cam-head G is turned partly around, so as to allow its edges to fall into the recesses a in the bar C, thereby causing the knives to fall down to the lower dotted line in Fig. 4, and spread the burrs and capsules apart on the pins R. When this has been done the handle is then raised into its irst position, so as to raise the knives to the point from which they irst started, and the plate P is removed, the capsules taken ofi', and the plates or another plate returned to the machine for repeating the operation described. Plates with smaller orlarger pins or formers R are employed, and the lever O can be used to alter the throw of the plate to correspond with the diameter ot' the differentsized pins used.

From the above description it will be perceived that the pins or formers R are all moved simultaneously and all in the same direction around the cutters.

I am aware ofthe capsule-cutting machines of F. A. Habel, in which the cutters are revolved, some in opposite directions to the oth ers, around fixed capsule-holders, and I do not claim such invention, my device being advantageous over the same in moving all the capsule-formers in the same direction simultaneously, whereby a separate gear-wheel for each capsule cutis rendered unnecessary, only tive wheels being used to cut as many capsules at one operation as may be desired, and whereby the pressure of the knives is always on the same side of all the holders.

It will be observed also that by my construction and arrangement a large amount of friction is saved, for in revolving-cutter machines the shank of each and every cutter must rotate independently in a separate bearing requiring lubrication, whereas by my construction neither the cutter-shanks nor the formers rotate in separate bearings, and therefore there is no chance of the 'oil from the machinery dropping upon the capsules. Moreover, in machines in which the cutters are carried around the formers, the cutters must rotate on their shanks, (again requiring lubrication, with its consequent disadvantages,) or else the wear would come on one partot' the edge of the cutter, whereas my cutters may be fixed on their shanks, thus requiring no lubrication, and yet have all of their surfaces in use, because the formers are carried allaround the cutters, thus bringing all the circumferences ot' the latter into use in cutting the capsules, and the rotation ot the cutters on their shanks is unnecessary. l

The construction of my machine, whereby the capsuleholders are moved, instead of the knives in the Habel machine, is also advantageous in allowing the knives to be raised or lowered much easier and with less mechanism than would be necessary to move the capsuleholders, and in allowing the main operating parts of the machine to be arranged under the capsule-holders, entirely out ofthe way, so as to prevent any lubricating-oil or other matter from falling upon the capsules, as would be the case with constantly-moving mechanism above the holder.
