MoLDlNG-tmAcHlNEi SPECIFICATION forming' part of 'Letters Patient N0. 752,484, dated February 16, 1904.

. Application iiled July 15, 1903. Serial No. 165,646. (No model.)

To all whom t may concern,.-

Beit knownthat we', JOHN JONES TURNER and JAMES ALBERTDOWLER, both citizens of the 'United States, and residents of Laharpe, in the county of Allen and State of Kansas,

have invented a new andImproved Molding- Y requiring the employment of skilled labor.

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

A practical embodiment of the invention is represented in the accompanying drawings,

forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. Y

Figure l is a sectional side elevation of the improvement. Fig. 2 is a reduced sectional plan view of the same on the line 2 2 of Fig; l. Fig. 3 is a plan view of one of the top plates of the carrier. Fig. 4 is a similarview of a bottom plate of the carrier. Fig. is a cross-section showing the attachment of the carrier-plates on the carrier-beam. Fig. 6 is an enlarged sectional plan view of the mcore and cut-OH knife for cutting off y the surplus material on the top of the mold. Fig. 7 is an enlarged sectional plan view of the stemjof the core and its driving gear-wheel. Fig, 8 is a side elevation of one of the molds in an open position, and Fig. 9'is a sectional -plan view of the samev in a closed position.

On a suitably-constructed base A is secured a hollow cylindrical standard B, on which is mounted to turn a carrier C for 'carrying molds D, operating, successively, in'conjunction with a core E, mounted to turn and t0 slide in the direction of its length in and out f of a mold at the time in axial alinement with the core, as hereinafter more fully described. The carrier C is preferably1 in the shape of an 'open framework supporting a top plate C and a bottom plate G2, made in ring shape and preferably in sections bolted or otherwise fastened to the radial beams of the open framework, as will be readily understood by reference to Figs. l, 2, 3, 4, and 5. The top plate C is provided with apertures C3, arranged in a circle for receiving the molds D, and on the top cf the bottom plate C2 are arranged annular retaining-hanges C4, likewise arranged in a circle and vertically in alinement with the *apertures C3 in the top plate C.

Each mold D is made in sections hinged together, which when closed iit the apertures C3 and rest with their bottoms Dl on the bottom plate C2 against the inner edges of the annular retaining-flanges C4, so as to hold the molds against lateral movement. The sides of the mold D arel provided with lugsDg, eX- tending lengthwise and fitting corresponding recesses C5 in the walls of the openings C3, so as to hold the molds against turning, as will bedreadily understood by reference to Figs. 1 an 3.

The bottom plate Czlis provided with apertures C, concentric with the annular retainingflanges Cfand adapted to receive the lower end ofthe core E to close the apertured bottom D of thel mold, the said core being so arranged relative to the mold engaged at the time that an annular space is left between the outer surface of the core and the inner surface of the mold for forming a vessel having a central opening, as will be understood by reference to'Fig. l.

The upper end of the core E is provided with a stem or shaft E', turning with and mounted to slide lengthwise in a bevel gearwheel F, in mesh with a bevel gear-wheel F', secured on a shaft F2, carrying fast and loose pulleys F3, connected by a belt with` other 'machinery for rotating the shaft F2, which by the bevel gear-wheels Fl and F imparts a rotary motion to the stem E and the core E to turn the latter.

On the stem E are secured collars E2 and E", between which is arranged a sleeve G, provided with a handle G', adapted to be taken hold of by the operator for sliding the stem E and its core E up or down out of or into the mold D then in axial alinement with the to slide in a bearing carried by an arm B', v

projecting from the standard B, and the upper portion of the stem E is mounted to slide and to turn in a suitable bearing carried by an arm B2, likewise projecting from the standard B.

In order to cut off the surplus material on the top of the mold D, a knife H is provided, secured to the upper end of the core E and flush at its cutting edge with the top edge of the mold, so that when the core E is in the mold and rotates then the knifeH is carried around with the core, and consequently cuts off the surplus material from the top of the mold to render the vessels formed of uniform length.

In order to lock the carrier C temporarily in position at the time a mold D is in axial alinement with the core E, the lower or bottom plate C2 is provided in its peripheral edge with notches C7, one for each retaining-flange C4, and each notch is adapted to be engaged by the upper end of an arm I, fulcrumed on a bracket I and provided with a treadle I2, pressed on at its under side by a spring I8 to hold the arm I normally in engagement with a notch C7.

From the peripheral edge of the top plate C extend radial handles C2, adapted to be taken hold of by the operator for conveniently turning the carrier C, and. with it the molds, at the time the core Eis in an uppermost positionthat is, out of engagement with the mold-so as to enable the operator to bring the next following mold in axial alinement with the core. Now previous to turning the carrier C the operator presses the treadle I2 with the foot, so as to swing the arm I out of engage ment with the corresponding notch C7 to unlock the carrier, and then by the operator manipulating the handle C8 a turning vmovement is given to the carrier C and its molds until the next mold comes in axial alinement with the core E. As the operator releases the treadle I2 the arm I snaps into the next notch (fand again locks the 'carrier C in place.

In order to insure an easy rotation of the carrier C, the latter is provided at its under side with depending brackets J, in which are journaled friction wheels J', mounted 't0 travel onan annular track J 2, secured to the ioor or .other support for the machine.

In order to keep the core E perfectly clean and smooth, a brush K is provided, secured on a bracket K', depending from the arm B', the free ends of the bristles of the brush engaging the peripheral face of' the core E, so that when the latter rotates and is moved up anddown by the operator out of and in the mold then the bristles of the brush K come in contact with the entire peripheral surface of The operation is as follows: The molds are inserted in the carrier C, and a lump or ball of clay or other material is thrown into the mold, and then the carrier C is held temporarily in a locked position by the arm I. 'Ihe core E, normally in an uppermost position, is now moved downward by the operator pulling the handle G in the same direction, sO-that the rotatingcore is wiped perfectly vclean by the brush K and passes into the mold D to press the lump or ball of plastic material into the space between the core and the inner wall of the mold, thus forming a tubular vessel, it being understood that the material is retained Within the mold D as the lower`- end of the core E passes into the opening C in the bottom plate C2. The surplus material on the top of the mold D is cut Off by the knife H, carried around by the revolving cors E, When the vessel has been formed, the operator pushes. the handle G' upward, so as to move the still-rotating sors ,E out of the mold, and then the operator presses the treadle I2 to temporarily unlock the carrier G to allow the o ,eltQl' to turn the carrier until the next mold) is in axial aline= ment with the core E, The above-described operation is then'repeated.

It is understood that the stem E is spl/ined a sufficient length to allow its up-and-down movement vWithout disengagement from the gear-Wheel F, S0 illlftl? t Continuous rotary motion is given to the stem E and its core E.

As shown in Figs. l, 8, and 9, the mold D is preferably made in its lower portion in the shape of the frustum of a cone and in its upper portion cylindriflal and the 001'@ E S similarly shaped to produce a tubular vessel having its lower portion in the shape ofthe frustum of a cone and the upper part cylindrical, so as to allow the convenient use of the vessel as a condenser for employment in retorts @f zinc-smelten.

IIO

The mold is made in hinged sections to permit of conveniently opening the mold in case the tubular vessel formed in the mold sticks to the sides thereof. In practice the mold is preferably greased on the inside to reduce the sticking of the vessel to the mold to a minimum. A handle D3 for carrying the mold about is arranged on one section of the mold and is adapted to engage a keeper D4 on the other section to lock the sections in a closed position.
