HOSE-COUPLING.

Specification of Letters Patent.

Patented Feb. '7, 1911.

Application filed May 24, 1910. Serial No. 563,059.

all whom it may concern:

Be it known that I, JorrN E. TV. Benson, a citizen of the United States, and a resident of Columbia, in the county of Esmeralda and State of'Nevada, have invented certain new and useful Improvements in Hose-Couplings, of which the following is a specification.

My invention is an improvement in hose couplings, and consists in certain novel construetions, and combinations of parts, hereinafter described and claimed.

The object of the invention is to provide a coupling of the character specified, which may be quickly connected and disconnected, by pulling the sections straight away from each other, thus avoiding the disadvantages of twisting the hose, and wherein an eflicient lock is provided for preventing accidental disengagement.

Referring to the drawings forming a part hereof, Figure l is a side view of the coupling with the sections separated, Fig. 2 is a similar view at right angles to Fig. 1, Fig. 3 is an enlarged perspective view partly in section of one section, Fig. 4 is a longitudinal section with the sections coupled, Fig. 5 is an enlarged side view of one section, and Fig. 6 is an end view.

The embodiment of the invention shown in the drawings consists of similar sections 1 and 1, each being tubular, and substantially cylindrical in shape, and having its bore enlarged at the outer end to receive the hose 2. The wall of the enlargement is undercut as shown at 5, and a shoulder 6 is provided between the enlargement and the bore, against which the end of the hose abuts.

At its coupling end, each section'is reduced annularly to form two annular shoulders 9 and 10, and one-half of that portion of the. section which extends beyond the shoulder 9 is rabbeted as shown at 7 to form a shoulder 4 on each side of the section, running parallel with the length thereof. The shoulders 4: extend inside of the annular shoulder 10 as shown in Fig. 3, and each shoulder 41: is provided on its face with a dove tail or undercut longitudinal groove a. At the inner end of each groove, the shoulder is also transversely grooved as shown at 26, the groove 26 intersecting the inner end of the groove l.

Each section is provided with a pair of spaced cars 11 extending outwardly above the shoulders 9 and 10, and spaced apart from the outer face of the reduced portion, and the ends thereof are substantially flush with the end of the section. The ears are transversely perforated at 12, the perforations being in alinement, and the outer face of each ear is cut away to form a countersink or recess 13, in which the perforation opens, and two openings 14: are provided above the recess. A bolt 15 is adapted to pass through the perforations, the said bolt having a longitudinal recess 16 in the side all thereof, and a lever 17 is secured to each end of the bolt by a screw 18.

lVhen the bolt 15 is engaged with the perforations 12, the lever fits the side and end wall of the countersink, and a plate 19 is secured to the outer face of the car by means of screws 20 engaging the openings li, and passing through registering openings 21 in the plate. As shown more especially in Fig. 3, the free edge of the plate is thickened. as indicated at 22, and is provided with spaced recesses 23. \Vhen the plate is in place, the recesses 23 are on opposite sides of the screw 18, and are adapted to be engaged by a lug 2 1 on the lever 17, to hold the bolt in adjusted position. It will be noticed that the plate is thinned transversely at 25 at approximately its center, and being of resilient material, that portion of the plate on the opposite side of the thinned portion from the recess 20 acts as a spring to hold the lever, while permitting the lugs to be easily disengaged.

At a point diametrically opposite the ears 11, each section is provided wit-h a lug 27, whose sides are cut away near its outer end 28 to form an car 29, which is recessed at 30, to form a nose 31, and a lip 32 overlying the nose but spaced apart therefrom. The recess 30 is shaped to fit the bolt 15, as shown in Fig. l, and the recess 16 of the bolt is of suflicient depth to receive the nose 31, when the bolt is properly turned to permit its entrance. The lip 32 overlies the bolt, and prevents lateral movement. The lever 17 is so arranged with respect to the bolt, that when the lug 2 1 is engaged with one of the openings 23 of the plate 19, the recess 16 of the bolt will be out of position for engagement by the nose as shown in Fig. 4, and when the lug 24L is engaged with the other opening 23, the nose will be received in the said recess.

A packing section 33 is connected with each of the coupling sections, each packing section being composed of a half-ring 3st having at approximately the center of its outer face a rib 35, provided with an annular flange 36, and at each end of the section, between the flange 36 and the half ring 34: is arranged a bar 37, each of whose faces is constricted longitudinally at its center at 38 to fit the grooves 4 of the shoulder at.

It will be understood that when the coupling sections are connected, the grooves r of the sections are in register, and the bar 37 is shaped to fit the two grooves. A semicircular gasket 39 is arranged on the outer faces of the portions 8st and 86 of the packing, the sections being grooved at eLO to receive the said gaskets, which assist in retaining the packings in position.

In coupling the sections, they are moved toward each other in the direction of the arrows in Figs. 1 and 2, the levers being turned 180 from the position shown in Fig. l, or in such position that the noses 31 will be received in the recesses 16 of the bolts. As they are pushed together, the bolt is rotated by the nose, so that when closely pressed together, the lever will be held by the engagement of the lug 2st with the proper opening 28 of the plate. To release the sections, the free ends of the levers 17 are pulled outwardly, until the lovers are at right angles to the hose, after which the sections are pulled apart. The lever 17 is partially covered by the plate, so that it cannot be caught and turned accidentally. The act of coupling is automatic when the levers are freed, and no turning or twisting of the hose is necessary.

It will be observed from an inspection of Fig. 5, that the ends of the levers 17 extend beyond the plates, so that they may be moved into such position that the nose 3i will engage with recess, after which, by merely pulling the sections apart, the bolt will be rotated to free the sections. The lever must be moved to a position at right angles to the hose before the sections can be pulled apart, so that there is no possibility of accidental uncoupling.
