FLEXIBLE PIPING.

SPECIFICATION forming part of Lettere. Patent No. 376,401, dated January 10, 1888.

Application led July 19, i887. Serial No. 244,712. (No model.)

To all whom 112? may concern.-

Be it known that we, FEANcIs MILTON WIEDER and GEORGE H. BENJAMIN, of the city, county', and State of New York, have invented certain new and useful Improvements in Flexible Piping, of which the following is a specification.

Our invention relates to iieXible piping, such as is designed to carry steam or other heated fluids or gases, and what will not be readily acted upon by the iuid or gases, and at the same time present a certain degree of mobility or iiexibility when in use.

Our invention has special reference to hose or piping adapted to be employed between railway-cars for transmitting steam or other heated gases. y

In the aecompan ying drawings, which illustrate our invention, similar letters of reference indicate like parts.

Figure 1 is an elevation of the main body of the piping and the various coverings superposed thereon. Fig. 2 isa longitudinal verti cal section. Fig. 3 is atransverse section taken on the line X X of Fig. 2. Fig. 4 is a transverse section taken on the line Y Y of Fig. 2.'

In the drawings, A indicates-the main body of the piping, made up of independent sections of spun or cast metal or other suitable material. Each section is so made that one end, B, is slightly smaller than the opposite end, C, whereby the end B of one section will t into the end C of the nextsection.

The sectional View, Fig.2, shows the sections A to have their surfaceformed convex' at the ends and concave in the center. By so arranging the sections considerable mobility may be obtained between the independent sections withoutseparating them or allowing the egress of the body transmitted. y

We do not wish to limit ourselves to theexact shape of the sections as shown, as the ball-andsoeket effect may be obtained in very many different way's; neither do we wish to limit ourquired purpose, the object of which is to form a packing-covering which will serve to lag the piping. Over this lagging D is indicated a layer of india-rubber or other material impervious to the passage of steam or gases. Vulcanite, Okonite, vulcanized'iiber, or like materials will answer a similar purpose. The external surface of the pipe we prefer to envelop with-a covering of woven cotton, F, such a covering as is usually employed for covering hosepipe, and which, when properly applied, will stand a very high internal bursting pressure.

We are aware that a hose made of a number of independent sections articulating with each other and contained within a covering or containing-tube has heretofore been made, and Such we do not broadly claim.

We claim as our inventionl. rIhe combination, in a fiexible piping, of the articulating section A, the non-combustible covering D, the limpervious covering E, and the outer covering, F.

2. The combination, in a iiexible piping, of the sections A, the ends of which, C B, are of different diameters, the non-combustible coveringD, the impervious covering E, and the outer covering, F, all substantially as described.

In witness whereof we have hereunto set our hands the 18th day of July, 1887.
