SOCKET-MOLD FOR SEWER-PIPE PRESSES.
SPEGEFICATIQN forming part of Letters Patent No. 320,325, dated June 16,1885.
(No model.)
To all whom, it may concern.-
Be it known that I, Ozms BARBER, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented a new and useful Improvement in Socket-Molds for Sewer-Pipe Presses, of which the following is a specification.
My invention has relation to improvements in that class of molds which are connected with a press in which the pipe is formed by pressing the clay in a plastic state through an annular orifice, and which molds consist of an outer mold to form the outside of the socket connected with the head of the cylinder containing the annular orifice, and an inner mold which can be raised to and locked against the outer mold until the socket is formed and then unlocked and removed. Heretofore it has been customary to have upon the press but one set of molds for each size of pipe, and, as a consequence, as much time and labor are consumed to make a single small pipe as a large one.
The object of my invention is to increase the capacity of presses for small pipe by providing devices by which two or more pipes may be made at each pressure.
My invention consists in the devices illustrated in the accompanying drawings, as hereinafter explained, and specifically pointed out in the claims.
In the accompanying drawings, Figure 1 is a vertical central section of the lower part of a sewer-pipe-press cylinder, and a similar section of a cylinder-head embodying my invention on the line 00 a: of Fig. 2; Fig. 2, a plan from beneath of said cylinder head Fig. 3, a vertical central section of the inside molds and supporting parts at the line .2 z of Fig. 4:, and Fig. 4 a plan from beneath of the inside molds and connecting parts.
The cylinder-head B, which is bolted to the press-cylinder A, is provided with four outlets, each of which constitutes the outer rim of an annular opening through which the clay is forced to form pipe, projecting from each of which said outlets is an outside socketmold, b, and within each is suspended an in side core or mandrel, a, by rods 0, connected with a ring, 0, which ring is supported by posts 6, resting on and attached to the head B. Each outside mold is provided with two hooks, 13 t, by which the inside molds are locked against them. Supported beneath the outside molds by a frame, I), are four in side molds, E, from each of which projects a a sleeve, F, which is mounted on a wrist, Gr, attached to the frame D. Upon each sleeve is a segmental gear, II, and above it a bar, I. Meshing with these gears is a central pinion, J, journaled on the post K, and turned by the handle L. The frame D is supported on a rod or shalt, M, which is arranged to move longitudinally in the line of the axis of the cylinder A, and by which the inside molds can be raised to the outside molds, in and against which they are simultaneouslylocked by turning the handle L and causing the bars Ito enter the hooks i. \Vhen the clay has been pressed into the space between the outside and inside molds, the latter are unlocked by the handle L and lowered by the rod M, and the four pipes run out to any desired length,when they are broken ofi' and removed, and the operation repeated.
It is apparent that the number of sets of molds in any case will depend on the size of the press and the size of the desired pipe.
I claim 1. In combination with a sewer-pipe press having two or more annular openings, each provided with an outer socket-mold, a like number of inner socket-molds mounted on a single base,and arranged to be simultaneously locked in and released from said outer molds, substantially as and for the purpose hereinbefore set forth.
2. The combination, in a sewer-pipe press, of the head B, provided with molds b, mandrels a, and hooks i, with the frame D, having the wrists G, the molds E, mounted thereon, and the segmental racks H, bars I, pinion J, and handle L, all constructed and arranged substantially as shown, and for the purpose specified.
Intestimony that I claim the foregoing I have hereunto set my hand this 20th day of March, A. D. 1885.
OZIAS BARBER.
