ToaZZ whom it may concern:

Be it known that I, JOHN' J. VAUrrER, a citizen ofthe United States of America, re-

siding at the city of New York, county and.

State of New York, haveinvented certain new and useful Improvements in Gas-Tubing, of which the following is a specification.

This invention relates more particularly to tubing adapted for conducting heating or lighting gas to the burners of laundry irons, stoves,lamps, etc., and has for its object to provide a very strong and flexible and practically fire-proof .gas tubing which will safely resist heavy external transverse pres sure and which will be protected from quick indentation 0r cutting-of the tube composition 8 by constrictive pressure of said fwire abrasion or wear when in use.

The invention'will first be described and then will be particularly definedin claims hereinafter set forth.. I

. of a piece of tubing of the preferred'construction and showing inv detail the elements of which it is composed. Fig. 2 is acrosssection of said tubing drawn to a larger scale; Fig. 3 is a broken or sectional side view of tubing having a slightly modified construction; and Fig. 4 is an enlarged crosssection of said modified tubing.

First referring more specially to Figs. 1 and 2 of the drawings, the numeral 5 indicates the innermost tube element formed as a foundation wire spiral outside of which is applied a wrapping of any suitable dampproof material 6, which may be treated paper or other fibrous substance. Outside of said material 6, is placed a fibrous braided textile tubular layer 7 to which is applied any ordinary ,coating or composition 8 having necessary fluid-tight and flexible qualities such as a glue and glycerin compound. It is preferred to apply outside of the composition 8, any suitable layer or other covering such as a braid 9, around which is applied a wrapping or covering 10 of any suitable substantially fire-proof material, such as asbestos, which is held in place by an exterior wrapping of open-coiled semi-fire In the modified tubing shown Figs. 3 and 4, the fibrous or textile layer 9 surrounding the composition layer 8, is omitted,but

otherwise this form of the invention is similar in. structure and operation to the first described tubing shown in Figs. 1 and 2 of. the drawings. The particular advantage ofusing the fibrous layer 9 "is that it allows the asbestos wrapping 10 and the snugly coiled external armor wire. 11, to bev applied more quickly during manufactureof the tubing, or before the plastic composition 8 has had time to fully assume its normal seasoned state.;--.Sa1d fibrous layer 9, also forms a-cushlon which prevents in urious as it is coiled around the asbestos wrapping 10, and meanwhile also prevents'injury to or cutting of the somewhat delicate asbestos 10 by pressure of the outer coilwrapping ing wire. 1

The interior flexible openecoiled wire foundation 5, coactswith the exterior coiled armor wire 11, in giving great transverse strength to the tubing which enables it to safely withstand comparatively heavy transverse pressures when 1n 'use,as for lnstance when accidentally stepped upon or when struck by falling objects or when otherwise subjected to pressure tending to crush the tubing. While thus assuring maximum 8, whereby said wrapping 6 protects the composition from erosion or other injury by such acids. If the coil 5, be made of metal or other material not containing acids or substances which would injuriously affect the composition 8, said wrapping 6, may be dispensed with.

I am not aware of any prior tubing which combines in its construction an interior transversely reinforcing wire coil, and an exterior transversely reinforcing semi-fireproof wire coil' armor applied directly over or around a layer of asbestos or other substantially fire-proof material, together with intermediate fibrous or composition layers, as in this invention, the object of which is to assure that the external fire-proof layer aided by the surrounding Wire coil armor shall amply protect the interior tubing layers from injury by external heat or by contact With heated surfaces While said armor coil also prevents quick external frictional Wear of the tubing, and While both interior and exterior Wire coils give maximum trans verse strength to the tubing Without sacrificing its necessary flexibility and elasticity.

Flexible tubing having varying diameters and made in accordance with this invention may advantageously be used for conveying fluids other than heating or lighting gas, as for instance, the tubing may convey compressed air to riveting machines or to stone carving or cleaning machines, or for other purposes, as will readily be understood.

I claim as my invention 1. Flexible gas tubing comprising interior and exterior Wire coils, an interposed layer of fluid-proof composition, and a layer of substantially fire-proof material applied outside of said composition and next Within the outer Wire coil, substantially as described.

2. Flexible gas tubing comprising interior and exterior Wire coils, a Wrapping of dampproof material applied outside the inner coil, a fluid-proof composition layer surrounding said damp-proof Wrapping, and a layer of substantially fire-proof material applied outside of said composition layer and next Within the outer Wire coil, substantially as described.

8. Flexible gas tubing comprising interior and exterior ire coils, an interposed layer of fluid-proof composition, a guarding fibrous layer applied outside of the composition layer, and a layer of substantially fireproof material applied around said guarding fibrous layer and next Within the outer Wire coil, substantially as described.

4. Flexible gas tubing comprising interior and exterior Wire coils and interposed layers including a Wrapping of damp-proof material applied outside the inner coil, a composition layer having a fibrous foundation ap plied outside the damp-proof Wrapping, and a layer of substantially fire-proof material applied outside said composition and next Within the outer Wire coil, substantially as described.

5. Flexible gas tubing comprising inte rior and exterior Wire coils and interposed layers including a Wrapping of damp-proof material applied outside of the inner coil, a composition layer having a fibrous foundation applied outside of the clamp-proof Wrapping, a fibrous guarding layer applied outside of the composition layer, and a layer of substantially fire-proof material applied around said fibrous guarding layer and next Within the outer Wire coil, substantially as described.
