LAMBERT B. BATTIN, OF ELIZABETH, NEW JERSEY;

HYDRAULIC PIPE.

SPECIFICATION forming part of Letters Patent No. 367.262, dated .Tuly 26, 1887. Application filed March 25, 1887. Serial No. 232,420. (No model.)

To aZZ whom it may concern.-

Be it known that I, LAMBERT BERGMAN BATTIN, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Hydraulic Pipes, of which the following is a specification.

Myinvention relates to animproved pipe for underground use, and is especially adapted to be employed for conveying waterf My invention in the present instance relates to the manner of constructing and assembling the parts thereof, whereby a better pipe is produced than. any now employed for I the purpose above described.

- purpose of giving shape to the intermediate Hcretofore the great difficultiesencountered by engineers have been the rotting away and breaking, by'disintegration or otherwise, of

the component parts of the pipe, thus causing agreat expense in the relaying and .repairing of the same from year to year. To obviate these drawbacks is the object of my invention *which I will now proceed to describe.

It consists in forming an iron tube with aninterior lining of cement, and of surrounding the pipe with the same material, and incas ing the latter with a second iron pipe for the cement, and also for strengthening and protecting the wholestructure. This outer shell or casing of metal I form with a number of perforations or openings, to provide for the escape of the air, which would otherwise be confined when filling in the space between the inner and outer metallic shells. By my process, therefore, of making these pipes, I ma pense with this dangerous and inevitable drawback in all pipes of this class now manufactured. These air-spaces that are formed in the style of pipe now in nseform weak places, and the pipe at these points very soon rusts and gives way, thus causing leakage and damage.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 is an end elevation. Fig. 2 is a crosssecti0n,and Fig. 3 is a plan view showing the perforations above referred to.

In the drawings, (t represents an inner metallic shell, and B an outer, and between the two is placed the cement or other filling, O.

Theinner pipe, at, is also lined with cement, D. The outer pipe, B, is provided with perforations P, of any suitable size and arranged in any suitable manner.- These perforations may be small, as they will answer the purpose just as well and better than larger perforations or openings. After the inner pipe has been lined the outer pipeis set over it in the proper position relative to it, so as to center the inner pipe, and then the annular opening formed between the two pipes. is charged with the cement or other material. up and the cement is forced in, it can readily be seen that quantities of air would be confined and entrapped by the cement unless some provision was made for its escape. is the object of the perforations P, for as the cement is forced down, the air, which would out at the openings or perforations. By this means a perfectly solid structure is formed between the two pipes-'-a result which has not hitherto been accomplished in devices of this kind.

In lieu of perforating the outer pipe, as I have described, I may perforate the inner pipe, and by this means form vents for the escape of the air. This, however, is not an available means or process, and I'prefer the method I have shown and described.

Having thus described my invention, what I claim as new therein, and desire to secnre'by Letters Patent, is-

1. A pipe consisting of two concentricshells and cement or other linings, as herein shown, one of said shells being perforated, as and for the purpose set forth.

2. The herein-described hydraulic pi pe,consisting of two concentric shells with the linings O and D, and the outer shell provided with a number of perforations, substantially as and for the purpose set forth.

3. The herein-described hydraulic pi pe,consisting of two concentric metallic shells with the cement linings G and D, and the outer shell provided with a number of perforations for the escape of air, as described.

As the cavity fills This 7o otherwise be confined and entrapped, is forced
