HENRY KNIGHT, OF JERSEY CITY, NEW JERSEY.
IVIANUFACTURE OF HYDRAULIC-CEMENT PIPES.
Specification of Letters Patent No. 32,2918, dated May 14, 1861.
To all whom tt may concern:
Be it known that I, HENRY KNIGHT, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in the Manufacture of Hydraulic-Cement Pipes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying' drawings, forming a part of this specification, in
which- Figure l, is a vertical longitudinal section of my improved apparatus. Fig 2, represents a side elevation of the same. Fig. 3, is a transverse section of the pipe after it is manufactured. Fig. 4c, is a longitudinal section of two sections of my pipe, showing the mode of connectingl the same together.
rIhe red color-is designed to show cement which is applied for closing the joint.
Similar letters `of reference, in each of the several gures, indicate corresponding parts.
The nature of my invention consists 1st in certain means hereinafter described for manufacturing hydraulic cement pipe with a metallic strengthening tube intermediate between their inner and outer surfaces or circumferences.
It consists 2nd in certain means hereinafter described for manufacturing hydraulic cement pipe such as above named, with a metallic coupling ring at one of the ends of each section.
To enable others, skilled in the art, to make and use my invention, I will proceed to describe its construction and operation.
In performing with my invention, I employ the central stationary core B, adjustable hinged table C, cylindrical mold E, detachable collar and base piece F, substantially as described in the Letters Patent granted to me May 8, 1860, and in addition thereto use the following parts.
A represents a sheet iron pipe of smaller diameter than the mold F. This pipe is arranged over the core so as to divide equally the space existing between the core and the mold and rests upon the platform of the truck frame H of the machine, being steadied at its lower end by the base piece F, and centered at its upper end by means of a second detachable flanged plate I, as represented in Figs.l l and at. This plate I is very essential.
to the performance of my invention and I will here proceed to describe its manner of use--in the process of molding the sections of pipe-as follows:
The core B, mold F, pipe A, and table C, being arranged and adjusted in the relation to each other shown -in Figs. l and 4, the cap I is placed on top of the mold andthe pipe A, and when thus placed, communication from the top with the space c, between the mold and the pipe A, is cut off; but a free communication with the space between the core and the pipe allowed. The cement is now introduced into the space b, andrammed compactly into said space and around the mold. The caps can now be removed as the cement between the pipe A and the core will prevent the pipe from changing its position. Cement is now introduced into the space o, between the mold F and pipe A,and rammed to a high degree, except near the top of the mold. At this stage of the process, a cast iron coupling ring J is introduced at the top of the mold and forced down into the soft cement a short distance. The detachable collar G is next introduced between the metallic coupling ring and the upper portion of the core B, and forced down and revolved until the top edge of the cement coating to the pipe A is squared olf and made solid. The pipe is now completed, and it becomes necessary to remove the mold and pipe in order to repeat the operation and also transport the finished pipe to a place where it may be left long enough to set.
To expedite the removal of the mold and pipe, I arrange on the wheeled frame H, a revolving derrick L, with windlass 1I and spring hooks iT, N. And as soon as the pipe is molded as described, the hinged table is thrown up, as shown in Fig. Q and the spring hooks lowered and hooked into the eyes c, c, of the base piece E. Now by turning the windlass the base piece, mold and finished pipe are raised off the core to the position shown in Fig. 2, and then swung oii or around to the stand orplace provided for their deposit. The mold is opened at the proper time and withdrawn from the pipe and then swung back to its original position for a new operation.
The whole apparatus is arranged to run on wheels in order that it may be readily moved from place to place, as occasion may require.
By my invention, a compound iron and cement pipe which is cheaper and more durable than cast iron pipe, is produced. The same being cheaper, on account of the materials used and more durable, because it is not liable to corrode. The pipe produced after my process, possesses greater utility than cast iron pipe, as it does not vitiate the taste of the water flowing through.
Pipes made by my improved process, are also cheaper and superior to the well known cement pressurepipe for water and gas. Because the cost is much less-as not more than half the cement is required, and the sheet iron is incased on both sides at one operation, and the pipe can be tested before it is laid in the trench. Whereas the cement pressure pipe in use is not lined on the outside until after it is laid in the trench when the'ceinent is plastered under and over the sheet iron tube, which process takes a large amount of cement and does not insure. an equal distribution of cement at all points, and is subject to many inconveniences; as rain, heat &o. are liable to destroy or impair the work before it is completed, or while the cement is soft.
Pipes made after my improved process are also superior, as they are finished at the joint with a cast iron coupling ring J, which forms a part of the pipe itself, and which may be as readily tapped vas the ordinary cast iro water pipes.
That I claim as my invention and desire to secure by Letters Patent, is-
l. Manufacturing cement pipe with metallic pipe vintermediate between its inner and outer surfaces by arranging the metallic pipe over the core B, and within the mold F, so that it divides about equally the space between the core and the mold, and then placing an annular centering device I, between the pipe and the mold and introducing the cement first between the metallic pipe and the core and then between the pipe and the mold, all substantially `in the manner and for the purpose described.
2. Finishing the sections of the combination pipes at one of their ends with a metallic coupling extension J, by means and in the manner substantially as herein described.
HENRY KNIGHT.
