JAMES TAYLOR, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR IO EUGENE F. PHILLIPS, OF SAME PLACE.
Specification forming part of Letters Patent No. 221,125, dated October 2.8, 1879; application filed December 23, 1878.
To all whom fit may concern:
Be it knoivnthat I, JAMEs TAYLOR, of the city and county of Providence, in the State of Rhode Island, have invented certain new and useful Improvements in Flexible Gas-Tubing; and I do hereby vdeclare that the following specification, taken in connection withV the 'drawings furnished and forming apart thereof,
is a clear, true, and complete description of my invention.
My .improvements krelate to such flexible gas-tubin g as elnbodies a seamless tube of `soft metal, preferably lead, and the object thereof is to secure greater flexibility and' durability than has heretofore been attained in tubing of this class;
The use of thin lead in a layer and-layers in connection with a compact coiled wire foundation and textile materials treated with gummy matter, rubber, Src., is fully set forth in English patent of Hebert, No. 9,070, A. D. 1841, and the tube therein shown and described was intended for use as iiexible gas-tubing. The use of seamless lead tubing in the same connect-ion 4is also shown and described in the United States Letters Patent of J. Butler of J une 12, 1860, No. 28,647, without the coiled- Wire foundation.
The tubes of Hebert and of Butler are defrcient in iiexibility, and that of the latter, being unsupported within the lcaden tube, was liable to undue compression while in use.
For attaining the ends previously herein stated my invention consists in flexible gastubing having a central wire foundation in open coils, and a seamless tube of thin soft and ductilc metal united to said Wire coil, and corrugated to correspond with the convolutions of the Wire foundation.
To more particularly describe my invention I Will'refer to the accompanying drawings, in which Figure 1 represents, a short length of tubing embodying my invention. Fig. Zrepresents a piece ofthe coiled wire. Fig. 3 represents a piece of thin metal tube prior to the insertion therein of the coiled Wire.
The coiled Wire a, instead of being compactly coiled, as heretofore, when used with lead, is coiled openly, so as to leaveconsiderable space between the convolutions. The st 'unless leaden tube b, instead of being thick and heavy, as described in Butlers patent before referred to, is very thin and light, care being taken in its manufacture to avoid cuts or breaks therein. The coiled wire is carefully inserted into the tube, and the latter is then compressed, so as to corrugate it spirally between the convolutions of the wire. This spiral corrugation of the metal tube secures the desirable degree of flexibilit.y,and the wire foundation beingloosely or openly coiled affords proper resistance against undue compression of the tubing, and admits of greater flexibility than when compact] y coiled. The additional jacketings c outside the metal tube may be largely varied as to material and mode of application, and any number thereof may be employed, as they constitute no part of my invention except as an exterior protecting medium for the metal tube, and for attaining a desirable exterior finish.
To 'provide for any accidental leakage of the metal tube the jacketings employed should be composed of, or in part of, or treated with, any of the well-known gas-tightening materi- `als or compounds:
Having thus described my invention, I. claim as new and desire tosecure by Letters Pateut- Flexible gas-tubing containing a loosely coiled wire foundation and a seamless metal tube corrugated to correspond with the con- -volutions of' the coiled wire, substantially as describedf JAMES TAYLOR.
A Vitnessesu' CHARLES A. OURRIEE, FRANCIS S. DYER.
