10 strain and which therefore is well adapted for use with excessive pressures as ofswater, steam or other like fluids.
l"I o these and other ends hereinafter set 415 forth'the invention, generally stated, may be ering which' includes one or more seamless tubular woven plies^ having a fibrous or textile warp and a metal weft or filler which, in addition toimparting its 'own tensile and 2 mechanical strength to the hose, permits the fibrous or textile warp to be 'drawn `up very tightly and in consequence to' lmpart strength. Y i i Theiinvention also comprises the im rove- 25-.ments tov be presently described and ally claimed. v
-In the following description reference will be madeto the accompanvin drawing formingr part hereof and in whiclgi l Figure lis a side view of hose embodying f A feature's of the invention and withlthe overmgsorwrappings progressively removed f inner' tube shown at the right,

In the manner and by the means described the objects recited are attained'.
In connection with the embodiment of the invention chosen for illustration in the drawing it maybe said that 5 is the inner-tube as 55 of rubber material. 6 is a wrapping of adhesive material or fabric which, if-desired, 4
may vbe placed between the seamless tubular woven plies 1 and 2. 7 is an additional wrapping and 8 is a spirally wound outside cover. 60 In Fig. 1 the ends of the -wires constituting the metallic weft or iller are shown as bent outward.l OfA course the intention is not to limit the application of the invention to the general hose construction illustrated in the drawing or otherwise than as the prior' art and the appended claim may require because modifications in matters of detail and. form may be made -without departing yfrom the spirit of the invention. i 70 I claim: v 4 Hose having an inner tube of rubber mate- .rial'provided with a'covering which includes two seamless tubular woven plies each yhaving a textilewarp and a metal weft, the metal weft in the plies being oppositelyarranged a wrapping of adhesive material applied to t eA woven plies, and an external splral cover.
