IMPovED TOBACCO-PIPE MACHINE.

The Schedule referred to inthese Letters Patent and making part of the same.

To all whom 'it ymay concern:

Be it known that I, JOHN H. HOLLELY, of Brooklyn, in the county of Kings and State of New York, have invented an Improved Machine for Automatically Molding Tobacco-Pipes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the' accompanying drawing, making part of this specification- Figure l being a front elevation of the machine.-

Figure 2, a side elevation thereof, portions being in vertical section.

Figure 3, a plan of the same, some portions being removed by horizontal section.

Figures 4, 5, 6, 7, 8, 9, 10, and 1l, various views of parts det-ached,l to be designated in the course of the description.

Like letters designate corresponding parts in all of .the figures.

The clay, properly prepared and of the right consistency, having been previously molded or formed into charges or pellets, preferably of a cylindrical form, each containing the quantity of material required to i'orm a pipe, the machine receives these pellets, and automatically feeds them to the work and completely molds the pipes ready for drying and burning.

rlhe principal functional parts ofthe machine are a hopper tube, A, into which the clay pellets are first placed; a feeding-wheel or cylinder, B, which conveys the pellets into position over the mold; the mold C; a plunger', D, which forces the pellets down into the molds, and forms the interior of the pipe-bowl; a device, E, for piercing the hole through the stem of the pipe; and an oiling device, F, for oiling the interior of the mold when opened between the moldings of the successive pipes.

These parts, except the hopper tube A, which'fnlfils its otlice simply by the gravity of the pellets, all severally derive their movements from a driving-shaft, Gr, conveniently situated above the operative parts,

Vand having its bearings on standards, extending upward from the table or ti'ame on'which the other parts of the machine are mounted.

The feed-wheel or cylinder B has an intermittent revolving motion on a vertical axis or pivot, by means of a cani, H, on -the driving-shaft, G, acting on a ver tical rock-shaft, a, which moves a pawl, b, to operate against ratchet-teeth or projections c c, on the periphery of the wheel or cylinder.

` rlhe pawl is retracted by a spring or elastic cord, d, shown in tig. 3.

The ymold C is made in two parts, divided centrally in a vertical plane, and it opens to discharge the molded pipes by thc two halves being moved llorizcntally from each other, andis closed by opposite Inovements of the same.

'lhese movements ot' the mold-halves are effected I by means of toggles I I, set at the outer ends against fixed fulcrnms e e, and vat the inner ends pivoted to the said mold halves, the toggles being actuated by a cam, J, on the driving-shaft G, operating on a cross-head, K, whichhas a vertical reciprocating motion in guides j' f, and is connected with the toggles by rods g g.

The plunger D receives vits vertical reciprocating movement also from a cam, L, of proper form, on the shaft G.

The stem-punching device E derives its .forward movementfrom a cam, M, attached to wheel, N, which is secured to the driving-shaft G, and serves also as a iiy-wheel for the machine.

The motion from this cam is communicated through a connecting-rod, j, to a lever, k, and from that by a cord, band, or chain, l. Y

The return movement is effected by a spring and cord, m.

'lhe operative motions of the oiling device F are received from another cam, O, on the ily-wheel N,- through a connecting-rod, o, lever 1f, and cord, bami, or chain, q and thercturn motions are produced by a spring, T, and connecting-cord, Y

The'feed-wheel or cylinder B has any convenient number of apertures or chambers through it, to receive the pellets and convey them to the proper position over the mold; and the arrangement ot' the hopper-tube is such that when the mold-wheel is in stationary position each time with a chamber over the bowl aperture ofthe mold, another chamber will be directly under the'said hopper-tube to receive another' v pellet.

The feed-wheel rests on a stationary bed-plate, P,

which hold the pellets in their chambers of the mold# wheel.

This bed-plate extends ont over the main part of the mold C, which tits closely up thereto, to prevent the escape of any clay. p

There is' an aperture through this bed-plate, centrally over the bowl aperture of Athe same, and under the plunger. D, and ot' the exact size to allow the plunger to pass through and fit closely therein, so that no clay will escape thereby.

When plungers of diierent sizes are used,diti`erent plates, P P, are also used, havingapertnres respectively to tit the plungers.

The mold-halvesare secured to guide-rods or bars h 7L, which move in guides` t' t.

The inner or bowl endof the mold, when closed, rests on a step or seat, Q, tig. 2, which sustains it and holds it up close to the bed-plate above.

This step is adjustable np and down by means of a set-screw, s.

The mold-halves must be brought into close con- Y key, lu.

tact with cach other and held there unyicldingly durv nicely adjusted by lengthening or shortening the rods g g, which connect them with the sliding cross-head K.

A suitable mode of adjusting the length ofthe rods is indicated in figs. 5 and 6, which represent a rod divided, and the parts coupled together by a slot and set-screw, t., the adjustment being determined by a The plunger D drives the pellets of mold, filling every part thereof by its pressure, and finally shaping the interior of the pipe-,bowl therein.

Since all the clay of each pellet is driven into the mold, if there should be too much clay, as there frequently may be, to occupy the space in the mold, there lnust be a reliet' provided in order not to break the mold. I secure this reliet' by adcviee represented in tig. 7.' f

The driving cam `L acts upon a cam-seat, n, which is the short arm of a pivoted level', It, and the long arm thereof is connterweighted by a sliding weight, S. iVhen there is an excess of clay, the weight S is raised' and the cam-seat n yields tothe action of the cam without further depressing the plunger. `Thus all the clay is embodied in the pipe, cven when -it varies in quantity.

The pressure required to force down the plunger is adjusted by moving the weight S out or in on the lever 1i. y A

The plunger itself is adjusted by a screw-shank, which secures it to its seat.

AAnother more formidable diliiculty to overcome in moldingthe pipes is to provide for the admission of air into the bowl of the pipes as the plunger-is wit-hdrawn therefrom. Unless this is effectually done the =molding cannot bc accomplished, since the withdrawal ot' the plunger would cause the pipebowl to collapse. I have been able to eect this object only by one method, substantially as represented in` fig. 8.

'lhe plunger is tubular at the lower end, and there is a vent or vents, r, outward from said tubular portion, at some distance from the end. In this tube plays a loose rod, provided with ahead or valve, fw, which will tit and shut against the lower end of the tube; but when the head drops a little, as represented, there is a free passage for air down through the tube and around the valve into the pipe-howl. A crosspin, rt, or its equivalent, playing in the apertures o r, allows this slight up-and-down movement of the rod and valve. \Vhen thel plunger dcscendsrthe valve 1c presses on the clay, and is pushed upward thereby, so as to close the tube in the plunger and prevent its filling with clay. But as soon as the pipe has been molded, and the plunger begins to be withdrawn therefrom, the air flows in through the tube, depresses the valve w, and occupies the space in the pipe-bowl as the plunger leaves it. It is entirely automatic and' -effective in its action.' Any equivalent arrangement of the device. may be employed. i

After the formation of the pipe by the plunger I), and while it is still in the mold, the stern is pierced by a wire, U, held in and operated by the device E. It consists of two jaws, for grasping and holding the punching-wire, attached to a holder, which has a reeiprocating motion, in line with the pipe-stem, in a guide V, by lncans above described. These jaws open as they reach the extremity ot' their forward movement, leaving the wire'free to b e taken away. lhe projecting portion oi' the wire is then taken hold of by the hand of the operator, and, as the mold then opens, he, by means of thc wire, lifts the pipe therefrom.

There are caps W W on the outer ends of' the `mold-halves, which, as the mold closes, shut together and close the end of the mold, except a central hole clay into the' just large enough to allow the entrance of the punching-wire. The wire, withdrawn from the pipe, is again set in the holding-jaws, which, as they begin to be drawn back, are closed by the guide V, in which they move, and thus seize and continue to hold .the wire firmly till the next pipe-stem Ais-pierced by it. The guide V is held in a socket,'y, and adjusted in height by a set-screw therein. This guide has a centric with the central point of' the pipe-bowl, where the line of the stem aperture coincides with it in the bowl, so that, as molds for forming pipes with stems at dilerent angles io the bowl 'are u'sed, the'stemL punching device may be adjusted in proper relative position to said molds. Thus, in the principal figures of the drawing, the device is shown adjusted to a mold for producing pipes with stems set at an acute angle .to the bowl; but in fig. 9 it is shown adjusted to a mold for producing pipes with stems at 'right angles tothe bowl. l

After the molding of each pipe, and when the mold-halves are separated to the greatest extent, as indicated in fig. 3, the mold is oiled. lhe oiling apparatus F is provided with two perforated cylinders or flies Y Y, covered with flannel,'or other soft, porous, oil-absorbent material, and of the propel' size to fit the mold-halves.

flies have a reciprocating movement with the carrier of the device to raise them up into proper position between the mold-halves at the proper time, and also an outward movement from each other, just at the contact with the mold-halves. To effect this latter movement they are respectively pivoted on shafts, around which wind cords z e, as shown. These cords are secured at the other ends to stationary holders, made fast to the supporting-guide Z of the device. The. length of' the cords is such that their slack is taken up as the flies nearly reach the termination of their upward movement, and then, by drawing on the shafts thereof, they turn the flics outward, as rcquired.

The cord-holders are adjustable by a screw on the supporting-guide Z, or otherwise. This guide is are shaped, and is adjusted by a set-screw in an areshaped socket, concentric with the same'point in the molds as the guide V, and for a similar purpose, to suit molds for making pipes withl different-angled stems. i

The leading principles of this machine are applicable to machines for molding many other articles besides tobacco-pipes, and I inte-nd to apply them all, or part of them, as each particular case may require, to such purposes, making such changesonly in form, size, proportions, and arrangement the objects may demand.
