UNITED STATES PATENT OFFICE,

GEORGE HANCOCK, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR T() HI'A'ISELF AND JAMES M. RUTHE-RFORD, OF SAME PLACE.

HOSE-COUPLING.

Specification of Letters Patent No. 29,548, dated August 7, 1860.

To all whom it may concern:

Be it known that I, GEORGE HANCOCK, oi Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Hose-Couplings for Uniting Engine and Hydrant Hose by a Self-Locking Action; `and I hereby declare the ufollowing to be a full, clear, and exact description of the construction and operation of t-he same, reference being had to the annexed drawings, making part of this specification, in which- Figure l, is a longitudinal view of the coupling. Fig. 2, is a like view of the same with the outer shell or jacket removed. Fig. 3, isa like view and sect-ion of the coupling showing the manner of uniting and interlocking t-he two pieces.

Similar letters of reference denote like parts in all the figures.

In t-he drawings A, denotes the socket piece, and B, the nipple piece of the coupling, the nipple of the latter entering the former, and each being provided with a corrugated neck C, upon which the hose is fastened by winding the same with cord or wire.

71 L, h, are the latches which serve as fastenings. They are constructed in the form of levers, and secured to the barrel of the socket piece by means of the wire z', which both contines the said latches in the splines formed lengthwise in the surface of the barrel for their reception, and serves as a fulcrum or hinge for the latches to swing upon.

|The projections or catches s, s, s upon one end of the latches are made to enter the groove or recess d, formed upon the outer surface of the nipple by the hugging action of the elastic band I, which may be of india rubber or of coiled metal spring and encircles the barrel of the socket ,inclosing also the locking ends of the latches as shown in Figs. 2, and 4. By means of this elastic band the several latches are made to act simultaneously in locking the nipple within the socket, and the catches s, s, s, are furnished with a constant force, which renders the locking effect selfacting so that it is only necessary t0 press the nipple into the socket to form a connection, and securely lock the same therein. A washer or ring t, of leather is interposed between the forward end of the nipple and a like surface formed within the socket to prevent the water from escaping at this point.

The several catches are withdrawn in uncoupling by means of the metallic sleeve G, which surrounds the opposite ends n, n, n, of the latches or levers h, L, h, and turns loosely upon the neck C, of the socket. Upon the inside circumference of this sleeve are formed the wedges g, g, g, corresponding in number with the latches and again at the inclined faces of which the ends n, n, n, are pressed outwardly by the action of the elastic band I, at the opposite end as shown in Figs. 3, and 5, so that by turning the sleeve in the direction 'shown by the arrows, the ends n, fn, n, will be depressed simultaneously in direction toward the center of the sleeve, thereby lifting the catches s, s, s, upon the opposite ends, from the groove d, and thus unlocking the coupling.

The body or barrel of the socket is inclosed within a metallic shell or jacket H, to protect the latches and the parts acting therewith from injury.

The coupling being constructed according to the foregoing description operates as follows: By pressing the nipple into the socket, the advance edge of the nipple forces the catches s, s, s, outwardly and in opposition to the constant force of the elastic band I, until the groove d, arrives beneath the catches, when the latter' are forced thereinto by the reaction of the elastic band, and the locking is effected instantaneously, the coupling action is then complete, the advance edge of the nipple presses against the washer t, and forms a tight joint therewith; and the force exerted constantly by the elastic band guards against any accidental uncoupling.

To disconnect the two parts of the coupling, the sleeve G is turned upon the neck C, in the direction indicated by the arrows, when by the actionhereinbefore explained the catches s, s, s, are withdrawn from the groove d, the nipple is at once liberated, and the uncoupling is effected.

I do not claim fastening the two parts of a hose coupling by means of spring clam s, or clutches which are controlled by a sli ing I claiml. The combination of the lever catches h, h, h, with the elastic band I, or its equivalent substantially as described for the purpose specified.

2. The sleeve G in combination therewith constructed and operating as described, for the purpose specified.
