Hose-Couplings.

l INVENTDR AUlvITnn STATES PATENT Orrron.

VILLIAM A. OASWELL, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR OF TWO-THIRDS HIS RIGHT TO EDWTIN M. VALDBON AND EDWIN V. BOWEN,

OF SAME PLACE.

INI PROVEMENT IN HOSE-COUPLINGS.

Specification forming part of Letters Patent No. 149,44l, dated April 7, 1874; application filed February 18, 1874.

To all whom it may concern Be it known that I, VILLIAM A. GAswnLL, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Hose-Couplings 5 and I do hereby declare the following speciiication, given in connection with drawings furnished, to be a true and exact description thereof.

My invention rela-tes to the swivel and tailpiece of a hose-coupling; and consists in casting one inside the other in such a manner as to connect the two parts, and allow one to revolve upon the other without the possibility of being pulled apart while in service.

Figure l represents a hose-couplnig, with my improvement drafted in sections, and lettered to correspond with those in specifica tion.

Letter A represents the swivel part ot a hose-coupling, with a screw-thread upon its inner surface, extending half its length, and terminating at a recess in the large end also, a lip or ring at the extreme large end, inside and outside, with a concave hand and horns, which I do not claim, except in combination. Letter B represents the tail-piece, with round spiral grooves upon its outer surface, and a iange, E, against which the swivel turns, and against which the band swings up in connecting the tail and band together. Letter C represents the ring or lip at the extreme end of swivel A. Letter II represents the ring or lip at extreme large end of tail B. Ihus it will be seen that the two parts are held firmly in position by the interlocked collars. Letter D represents the collar or ring on the lower side of flange E, on which are cut spiral grooves to match the one on tail-piece, and, also, in the band. Letter h represents the band, having round spiral grooves upon its inner surface the whole length, to match one on tail B and collar D. As the band is screwed down over the outside otl the hose, it catches into those on the collar D, connecting the two parts together irmly.

I do not clailn the round spiral grooves as my invention, except in combination.

In attaching couplings to rubber hose, whenever any part of the metal pieces has to revolve upon the `rubber a great amount of friction is created. To entirely overcome this I insert a piece of strong paper under the band as an anti-friction substance. (Reference to A.)

An explanation of the process by which I connect the swivel and tail-piece of a hosecoupling together by pouring the metal, while in a liquid state, into a cast swivel, will enable all to understand.

I first cast the swivel and finish it, then cut the recess which forms the lip at the extreme end 5 then I wash these parts in clay-paste, and thoroughly dry out all dampness. I then prepare a sand core, and slip the swivel f down over it, a-nd against a shoulder provided to receive it near one end. The whole is then placed in the mold, an d theliq uid metal poured in, findin g its way into recess in the swivel, and around the core, forming the tail-piece. As the metal cools it shrinks sufficient to leave one loose within the other, and allow it to revolve easily.

Having described my invention, I claim as new, and desire to secure by Letters Patentl. The swivel A and tail-piece B of a hosecoupling, connected by casting one part to the other, as specified.

2. In combination with the tail-piece B, collar D, and iiange E, the interlocking flanges O and H, as and for the purpose specilied.

\VILLIAM A. OASVVELL.
