HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 557,423, dated March 31, 1896. Application filed December 3, 1895- Serial No. 570,923. (No model.)

To all whom it may concern: throughout to the larger diameter of the 50 Be it known that we, THOMAS ALEXANDER aforesaid shoulder 13. OUTHOUSE and ALBERT ELDE BOHLEN, of A11 offset or extension 14 is formed longi- Mount Olive, in the county of Macoupin and tudinally at each side of the outer face of the State of Illinois, have invented a new and head portion 12 of the female coupler-section,

Fig. 3 is a section lars or thimbles 17 and over the outer end surtaken through the coupled sections and pracface of the apertured portions of the latches,

The coupling comprises, as usual, a female being made to rest either upon the tie-rods sectionA and a male section B. The female 21, or the lower ends of the springs are sesection consists of a shank 11, to which the cured to the outer end portions of the collars hose 10 is clamped in any suitable or approved or thimbles 17 by means of flanges formed 0 manner, and a body or head 12. \Vhere the upon the outer end surfaces of the nuts 22. body of the female section connects with its The outer end surface of each latch-shank shank an interior shoulder 13 is formed, the is provided with a cap 24, the said caps being said shoulder being preferably beveled, as of sufficient diameter to slide over the nuts shown in Fi 2, the contracted portion of the 22 a predetermined distance, and the outer 5 shoulder being at the inner termination of ends of the springs 23 have bearing against the shank, and the bore in the head portion the inner faces of the said caps, and the caps of the female section is of even diameter may be screwed inward on the latch-shanks until they engage with offsets on the nuts 22. When the caps, however, are removed from the offsets on the nuts, which position is their normal one, the springs 23 will act to carry the bottom portions of the latches upward within the chambers 16 a sufficient distance to cause a portion of each latch to interrupt the bore 15, in which it is placed in a longitudinal direction, as shown in Fig. 2.

The male section B of the coupling comprises a shank 25, to which the hose 26 is secured, and a body or head section 27, the latter being provided with exterior offsets or extensions 28 at its sides, corresponding in location to the offsets 14 of the female section. The male section is provided with a central tubular tongue 29, which projects outwardly in a horizontal plane beyondthe front of the body or head 27, and the exterior diameter of the tubular tongue 29 is such as to permit it to enter and closely fit in the bore of the head portion of the female section A. Near the end of the tubular tongue 29 an annular recess 30 is made in its exterior surface, and the inner end wall of this recess is given a rearward inclination, as shown in Fig. 2. The recess 30 produces a flange 31 at the extreme outer end of the tubular tongue, and in this flange a number of openings or apertures 32 are made, extending through into the recess 30. The recess 30 is adapted to receive a washer 33, which has bearing against the inner face of the flange 31, and the rear portion of the washer is beveled practically to correspond to the beveled end of the aforesaid recess 30.

A stud 34 is securely fastened in the forward end of each extension 28 of the main section of the coupler, and the length of the studs and their diameter are such that the said studs will readily enter the bores 15 in the offsets or extensions of the female section A. In the inner side of each post or stud 34: a recess 35 is produced, and the outer end of each post is preferably pointed or rendered somewhat conical. I

In effecting a coupling of the two sections the tongue 29 of the male section is made to enter the body of the female section, and the studs of the male section will thereupon enter the bores in the offsets of the female section, and when the head portions of the two sections are brought together, as shown in Fig. 2, the latches 18, which will have been depressed by the posts passing through their apertures 20 when the recesses 35 of the posts register with the apertured portions of the latches, will be carried outward by the springs 23 to such an extent that the inner portions of the latches will enter and fill the recesses in the posts, thus securely locking the two sections together.

hen the couplingis completed,the flanged end of the tongue 29 will rest against the enlarged portion of the shoulder 13 in the interior of the female section, and as soon as the water is turned on it will therefore be permitted to enter the apertures 32in the said flange 31 and crowd the washer 33 up firmly against the inner wall of the female section, thereby effectually preventing the possibility of a leak.

To effect an uncoupling, all that is necessary is to press inward upon the two caps 24, whereupon the latches 18 will be released from engagement with the studs 34:, and the two sections may be readily separated. After a coupling has been made the nuts 22 will be screwed outward until their projections engage with the caps, thereby preventing the caps being pressed inward to effect an 1 uncoupling until such action is desired.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. In a hose-coupling, a female section provided with spring controlled. latches exteriorly operated and bores in which the said latches have movement, and a male section provided with keeper-studs adapted to enter the said bores and be engaged by the said latches, and a tubular tongue adapted to enter and be contained in the water-chamber of the female section of the coupling, as and for the purpose specified.

2. In a hose-coupling, a female section provided with exteriorly-operated latches and bores leading to the said latches, also locking devices for the latches, and a male section having keeperstuds adapted to enter the said bores and to be engaged by the said latches, and a tubular tongue adapted to enter and to be contained within the water-receiving chamber of the female section, whereby a through waterway is provided between both sections of the coupler when in coupled position, as and for the purpose specified.
