HOSE GUUPLING.
No. 274,951. Patented Apr.3,1883.
UNITED STATES PATENT OFFICE.

HOSE-COUPLING.
SPECIFICATION forming part of Letters Patent No. 274,951, dated April 3, 1883.
Application filed October 24. 18S2.
To all whom it may concern:
Be it known that I, JAMES H. LUTHER, of Karns City, in the county of Butler and State of Pennsylvania, have invented a new and useful Improvementin Hose-Couplings; and I do hereby declare the following,` to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l is a longitudinal section of my improved hose-coupling, and shows the attachment of the ends of sections of hose to the coupling parts. Figs. 2 and 3 are end views of the two parts of the coupling. Fig. et is a perspective view of the split threaded ferrule or annulus which secures the end of the hose in' the coupling. Fig. 5 is an end view of the same before insertion into the coupling, and Fig. 6 is a side view of the entering end of the male part of thecoupling. y The male and female ends of the coupling are shown at a and b. They are secured to the ends ot' their respective sections of hose in the following manner: The piece a is bored out back of the entering section a to a diameter which is large enough to receive the end of the hose c a-nd the securing-ferrule d inside of it without reducing the straight bore ofthe coupling-piece.
At the extreme rear end of the piece ais an inwardly-projecting iange or nnnulus, a3, the corners of which are turned oft' so as to present a rounding surface. The enlarged portion a2 terminates at its front end in a square shoulder, a4, against which shoulder the end of the hose c abuts.
The parts are put together by inserting the ends of the hose c, with the securing-piece d inside of it, until it comes against the shoulder a4. I then insert an expanding-tool through the front end of the coupling-piece and expand or spread the securing-piece d, which is split, as at d', longitudinally for that purpose, until its ratchet-shaped'threadis embedded rnily in the inner surface ofthe end of the hose,and its diameter exceeds that of the shoulder or annulus a3, and until it makes a tight joint between the hose and the enlarged portion a2. Thus secured, it is impossible to draw out the hose from the coupling-piece a or to detach (No model.)
the latter from the hose o Without first reducing the diameter of the securingpiece d, for the reason that the securing-piece ol cannot pass the shoulder a3, and the hose c cannot be drawn out against the cutting-edges of the ratchet-shaped thread on' the securing-piece. While I prefer the ratchet-shaped thread, I do not limit myself thereto,nor to the use of any thread upon the outer surface of the .securingpiece d, but claim broadly an expausible securing-piece which may be forced outward against the hose, so as to cause it to be firmly packed between the adjacent surfaces of the securing-piece and of the coupling-piece. The coupling-piece b is constructed and secured in like manner, the parts b2 b3 corresponding to the parts a2 a3.
On the outer surface of the entering section a are inclined lugs a5, preferably three in nun1- ber, and arranged at equal distances ou the circumferencea short distance back from the end. On the inner surface of the bowl-piece b,and at the outer end of the same, are inclined projecting lugs b5, similar to and designed to engage with the lugs a5. At the inner end of the bowlpiece b is a groove, e, and back of the groove o is a seat, c2. The purpose ofthe groove e is to receive a packing-ring, e', made of leather or other suitable material, which is designed to be loosely inserted in the groove e. The face of the seat c2 is corrugated or grooved, as at e3, Fig. 3, so as to admit the water behind the packing-ring c, for the purpose of holding it up lirmly against the square end of the entering piece a' by the head or pressure of the water. This feature is especially valuable, in that it makes a tight joint, even'when the lockinglugs on the coupling do not draw the end of the entering part a against the packing-ring, so as to force it against the seat o2. ltis necessary, however, in all cases, that the end of the entering piecel a shall projectV into the bowl-piece b far enough to be liush with the outer edge ofthe groove c, so that when the pressure of the water cornes upon the packing-ring e' it shall be forced forwardl against the end of the entering piece c.
Projecting from the outside of the sections IOO I have spoken of the packing-ling as being loosely inserted in its containing-groove and as seating against the end ofthe entering pipe. 1 do not, however, limit myself to the use of a packing-ring which has an actual movement in its containing-groove, for the reason that when the seat e2 is grooved, as described, the water can iind access to the back of the packing-ring, even when it ills the groove sutiiciently to prevent any movement therein. By loose I mean a packing-ring which does not pack to make a tight joint by beingcompressed tightlybetween rigid surfaces.
I do not limit myself to the use of my innproved coupling for hose, but claim it generally for Water and similar pipes.
The dan ge or annulus a3 is rounded for the purpose of preventing it cutting the hose when securing in the coupling-piece by the securing-piece d. In Fig. 5 I showr the securingpiece d in the shape in which it is when inserted into the coupling.
Vhat I claim as my invention, and desire to secure by Letters Patent, is 1. The combination, ina hose-coupling, of a bowl-section having a packing-groove, and an entering section, the end of which comes flush with the outer side of the packinggroove,with a packin g-rin g of less thickness than the width of the groove, substantially as andjfor the purposes described.
2. The combination of a hose-coupling having an inwardly-projecting shoulder or annulus at its rear end with a section of hose and an expansible threaded securing collar or annulus, substantially as and for the purposes described.
3. A hose-coupling consisting of an entering section provided with inclined lugs, a bowlsection provided with insideinclined lugs for engaging the lugs on the entering section, a loose washer placed in a groove and seating against the end of the entering section by the pressure of the water in the pipe, and hose- JAMES vH.
