Description

5t-atta' ctw The Schedule referred to in these Letters Patent andmalsing part of the same.

To all whom it ma/y concern:

Be it known that I, J AMES DAvIs, of Pawtucket, in the county of Providence, and State of Rhode Island, have invented a new and'useful Improvement in Y Flexible Hose; and I do hereby declare that the following specification, taken in connection with the draw- 4 ings making a part of the same, is a' fu-ll, clear, and exact description thereof.

, Figure l is hose.

Figure 2 is a transverse section. My invention consists in constructing a hoseV from two or more thicknesses of leather, Whose surfaces in n n li I a' view in perspective of my improved contact are united by means of an interposed coating of adhesive cement, made from gutta-percha, or other gum which is impervious to water, whereby I am er abled to preserve the` leather so protected from the decay and destruction which result from its becoming soaked in conveying water under high pressure, and consequently'increase its durability.

I, also claimthat the capacity of resistance to internal pressure of which a hose so constructed is capable, is very much greater than lthat of a hose Vmade from single skins of equal thickness.

In the drawings, a hose is represented made from two thicknesses of leather, A and B, which are cemented together, asseen at a.

' The skins from `which the hose is to be made are to be cut and lapped, so as to make, when united, a long strip.

VTwo or more of these strips 'of leather are to be piled upon each other,thelsurfaces to be brought in contact having been rst thoroughly coated with a thick layer of guttappercha dissolved by naphtha, turpentine, or other suitable solvent.

"lhe surfaces offthe leather forming the laps shnld also be coated with cement, and the laps are to be fastened by rivets in the usual way.

A long strip of lengths of leather united, sufficient to form the required section of hose, is thus made, and this is formed into a hose by lapping the edges and riveting them in the manner well understood.

Any other preferred method of making up the hose may be employed, as the invention resides not in the manner in which it is put together, but in the use of twcor more thicknesses of leather, whose contiguous surfaces are united by water-proof cement.

I do not seek to claim as new the application of rubber, or equivalent gums, tp leather hose, for rendering the same impervious to water, inasmuch as the use of rubber for coating the interior of leather hose is 'described in the English patent to Wilson & Son, No.4

2,880, for `1858.

What I claim as my invention, and desireto secure by Letters Patent, is- I.

' A flexible hose, made of two or more thicknessesof leather, whose surfaces are united by water-proof ad-` hesivecement, substantially as herein described.
