HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 767,966, dated August 16,1904.

Application filed December 26, 1903. Serial ITO-186,646. (No model.) I

To all whom, it may concern.-

Be it known that we, FRANK A. SILVIS and FRANK J. BACKER,CitlZenS of the United States of America, residing at Millvale borough, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in I-Iose-Couplings,of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in hose-couplings, and relates more particularly to that class wherein the use of screw-threads is entirely dispensed with.

The present invention has for its object the provision of novel means whereby two sections of hose may be readily coupled together and easily uncoupled when desired. Furthermore, the coupler may be easily secured together in the dark, as the parts are constructed in such a manner that will permit the same to be placed together with the greatest ease.

Our invention further aims to construct a hose-coupler that will have special advantages for the coupling of fire-hose, as the same may be dragged over rough surfaces without liability of becoming uncoupled.

A still further object of our invention is to provide ahose-coupler which will be extremely simple in construction, strong, durable, comparatively inexpensive to manufacture, and highly efficient in its use.

With the above and many other objects in view the invention consists in the novel construction, combination, and arrangement of parts, to be hereinafter more specifically described, and particularly pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this application, and wherein like numerals of reference indicate like parts throughout the several views, in which Figure 1 is a side elevation of our improved hose-coupler. Fig. 2 is a vertical sectional view thereof. Fig. 3 is a perspective view of the female member. Fig. 4: is a like view of the male member. Fig. 5 is a longitudinal sectional view of Fig. 2, showing the female and male members partly broken away.

In the drawings the reference-numeral 1 indicates the male member, and 2 represents the female member. The female member 2 has formed therein an interior seat which is provided with a gasket 3 and provided with an interior collar 4:. This female member 2 carries bearings 5, in which is pivotally secured a spring-pressed locking member 6, which is spring-pressed by means of a retractile spring 7, secured. at 8 and extending in the recess 9, the said spring engaging the under face of the hook 6. The said hook carries an extension 10, which extends beyond the female member, engages in the recess 1 1, formed in the male member, said male member'also havingformed upright walls 12, which form guides for the hook member. The female member has cut-away sides 14, forming shoulders 15 16 on each side, and a further recess 17 is formed on the sides forming shoulders 18. The male member is provided at its engaging end with forwardly-proj6cting cheek-pieces 19, which fit in the recessed sides of the female member, and have shoulders or enlargements 20 on their inner face to fit the said recesses in the female member, the ends of the cheek-pieces being shaped to correspond to the inner terminating ends of the recesses. In the male .member at its engaging end is a tapered seat 21, which receives the tapered end 22 of the flexible gasket 8, seated in the female member and held secure in its position by the expanded metal ring 4. To uncouple the sections, the hook or catch 6 is disengaged from notch 11 by lifting upwardly on the hook end 10, and the male member pressed downwardly, throwing the cheek-pieces out of engagement with the female member and disengaging the members.

To connect the members, the male member is arranged to one side of the longitudinal axis of the female member, so that the enlargements 20 will enter in the recesses 17, and as the said male member is forced upwardly into alinement with the female member the gasket 3 is seated in the male member and hook end 10 of the catch 6 engages in the notch 11 and holds the members in the coupled position.

In the practice of the invention it will be noted that various slight changes may be made in the details of construction without departing from the general spirit of the invention.

Having fully described our invention, What we claim'as new, and desire to secure by Letters Patent, is

1. In a hose-coupling comprising two members, one of said members having its sides cut away to provide forward and rearward shoulders, the sides intermediate said shoulders being recessed to form another pair of shoulders, one of which is arranged below the first-named shoulders, extended cheek-pieces carried by the other member, said cheek-pieces being adapted to be received in said cut-away portions and having their inner faces formed with enlargements to engage the last-named shoulders, and means for locking said members in a coupled position.

2. In a hose-coupling, a member formed on one of its sides with a pair of alining shoulders, and being recessed to form a second pair of shoulders, one of which is intermediate said first-named shoulders and the other therebeneath, a second member having a cheekpiece abutting the first-named shoulders, an enlargement on the inner face of said cheekpiece abutting the last-named shoulders, a spring-pressed hook carried by one member, and means carried by the other member engaged by said book.

In testimony whereof we afiiX our signatures in the presence of two Witnesses.
