IMPROVEMENT IN TUBULAR SEAMLESS HOSE.
Specification forming part of Letters Patent No. 150,481, dated May 5, 1874; application led June 6, 1873.
To au 'whom it may concern:
Be it known that EDWIN M. CHAEFEE, late of the city and county of Providence, in the State of Rhode Island, did invent a new and Improved Tubular Seamless Hose, consisting Y of an improved braided fabric of fibrous material, made water-proof by lining it with india-rubber or gutta-percha and their vulcanizable or vulcanized compounds, of which the following is a specification:
The object of the invention is to make a stronger and better seamless water-proof hose in a cheaper mannerV by braiding than has hitherto been done by weaving. The invention herein described and claimed consists in incorporating longitudinal strands a in the` vances longitudinally three and two-tenth inches in making/"oneturn diagonally, or, in other Words, making a complete spiral in that distance, is near the true one, as the inventor found by experiment, when the diameter of the hose is two and three-.quarter inches, and when the area ofthe dischargeoriicc at the nozzle is equal to one square inch.
The longitudinal. distance which a spiral turn should make is longer or shorter in proportion as the diameter of the hose is greater or less than the standard above given. A little expansion or contraction is admissible; yet an inconvenient expansion or contraction is liable to be produced-by the pressure Within the hose when `any material deviation is made from the spiral angle herein indicated.
The longitudinal strands before mentioned are useful inthe process of lining the hosetube with rubber, and are also useful to resist any longitudinal strain Which may occur in the absence of internal pressure.
This hose is made water-proof by lining it with vulcanizable sheet-rubber or gattapercha, which may be vulcanized or partially so, as well before as after it is introduced into the braided hose-tube. The lining of the hose may be accomplished by the methods patented to the said EDWIN M. OHAEFEE, October 2, 1866, or by any other feasible method.
Longitudinal strands have been introduced into flat braid before, but not into tubular fab- .rics for hose purposes.
The proper angle or spiral of the diagonal strands is secured by adjusting the speed of the take-up rolls of the braiding-machine, which withdraws the braided fabric from the mandrel or core, upon which it is formed or braided.
It will be obvious that the longitudinal strands may be laid in the braided fabric in a straight line, provided the spirally-laid strands cross each other on a straight instead of on a spiral line.
When the hose is braided and cut into proper lengths, care should be taken that the ends of the braid should not get raveled or frayed 5 and to secure that object it is advisable to dip the ends for about an inch into some adhesive substance, such as glue, shellac, or melted Wax, which, when dry or cold, secures the ends of the hose or its strands from raveling.
The application of the adhesive substance may be made at the proper place before cutting the hose into lengths.
