HOSE-COUPLING.

Specification of Letters Patent. Patented J 11116 13, 1916- Application filed July 15, 1915. Serial No. 40,107.

To all whom it may concern Be it known that we, MARSHALL HUBBARD and SAMUEL EDWARD HUBBARD, citizens of the United States of America, residing at 1610 Carey street, Ashland, VJisconsin, have invented. certain new and useful Improvements in Hose-Couplings, of which the following is a specification.

The present invention relates to new and useful improvements in hose couplers and has for its object to provide means whereby a hose may be easily and readily connected or coupled to a street water plug or the sections of a hose may be coupled together in an expeditious manner.

A further object of the invention is to provide a coupler of the character described that will be strong, durable and eflicient, simple and comparatively inexpensive in the manufacture of the same and-also one in which the several parts will not be liable to get out of working order.

With the above and other objects in view the invention consists of the novel features of construction, combination formation of parts as will be hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings has been shown the simple and preferred forms of the invention it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but the right is hereby reserved to make any changes, alterations or modifications to which recourse may be had without departing from the spirit of the invention and sacrificing the etliciency of the same.

In the drawings: Figure-1, is a fragmental view of an ordinary street water plug showing one cap thereof in elevation and the other cap and one outlet opening of the plug partly in section. Fig. 2, is a vertical section through the hose coupling. Fig. 8, is a front elevation of the outlet opening of the plug or the male member of the coupling. Fig. 4, is a front elevation of the female member or the section of the coupling which is secured to the hose. Fig. 5, is a front elevation of the cap when removed from the plug and illustrating a slightly modified form of the invention and, Fig. 6, is a vertical section through the same.

Referring now more particularly to the drawing like and corresponding parts are designated by similar reference characters throughout. I

The numeral 1 indicates an ordinary type of a street water plug having the usual discharge pipe or opening 2.

In Fig. lthe covers or caps are shown applied to'the discharge openings and when these caps are removed the hose is to be coupled thereto. The caps 3 are formed of one integral member forming a rear nipple portion 4: and a flanged portion 5. In the first figure of the drawing the discharge opening is provided with a flange or ring 6 and the outer face of this ring is provided with threaded recesses spaced equidistant apart for the reception of the bolts 7 These bolts project from the ring. and are each provided with an enlarged head 8. Formed within the flanged portion 5 of the cap and spaced equidistant apart are openings 9 which are a little larger in diameter than the exterior diameter of the bolt heads 8 whereby the bolt headsmay be easily and readily inserted within the openings. Each opening 9 is connected with an elongated slot 10 which is arranged concentrically within the flange 5. From the foregoing it is obvious that by inserting the bolt heads through the openings 9 and turning the cap the shank portions of the bolts will travel within the slots 10 and the heads of thebolts will rest on the outer face of the cap thereby locking the cap upon the discharge opening .of the plug and preventing any longitudinal movement of the cap which would cause a severance of the cap due to the water pressure contained within the plug. The cover can be readily removed by turning the same to the right until the bolt heads again register with the openings 9 and then by pulling outwardly onthe cap until the same is free of the bolts. Often when the caps have been applied to the plugs for some time rust or corrosion takes place thereby making it difficnlt to remove the same. In Fig. 1 the cap is provided with three recesses 11 in the'face thereof for receiving an ordinary spanner wrench whereby a firm grip may be obtained upon the cap for removing the same. In Figs. 5 and 6 the outer periphery of the cap is provided with two diametrically opposite arranged lugs 12 to which another form of spanner Wrench may be attached for turning the cap in removing the same.

Whenthe covers or caps are connected to the plug the improved connection'des'cribed 'will hold each cap at three points, that is where the bolts extend through the cap and to make a stronger connection by providing additional slots within the fiange 5 would be impossible as it would weaken the same. To insure a stronger connection the nipple 4 is provided with peripheral lugs 18 which are three in number. These lugs are adapted to be inserted within the longitudinally extending slots 1 formed within the flange 6 of the discharge pipe. As the cap is being turned when applied to the plug the lugs 13 will travel within the concentric grooves 15 thereby providing additional means for connecting the caps to the plug.

In Fig. 2 the hose is shown as coupled in position to the ring 16 which may be a portion of the plug or attached to another section of the hose. Instead of forming the flange or ring 6 integral with the discharge pipe of the plug as shown in Fig. 1 the ring 16 in Fig. 2 is provided with an internal threaded flange 17 which may be connected to the threaded end of an ordinary discharge pipe of a water plug instead of providing a specially designed discharge pipe as that shown in Fig. 1.

The numeral 18 indicates the threaded discharge pipe, but this may be a section of the hose when it is desired to use the coupling for connecting the sections of a hose together.

The ring 16 is also provided with bolts 7, and grooves 15 the same as the flange 6. The female member of the coupling comprises'a ring 19 having an opening therein of less diameter than the opening formed within the ring 16. A threaded flange 20 extends rearwardly from the ring 19 to which may be connected the hose indicated by the numeral 21. Openings 22 are also provided within the ring 19 having communicating therewith the elongated slots 23. The openings :22 are for receiving the bolt heads Sand by forcing the female member inwardly and then turning the same to the left the shank portions of the bolts will travel within the slots 23 and thereby lock the members of the coupling together. By turning the female member to the right until the openings 22 again register with the bolt heads the female member may be removed by pulling outwardly on the same. The outer face of the ring 19 is provided with a recess 2% for the reception of apacking ring 25 and a flanged retainer 26 is provided for holding the packing in place.

Having fully described the invention and what we claim as new and desire to secure by Letters Patent is 1. A coupling comprising a ring having threaded recesses formed in the. outer face thereof, bolts detachably mounted within the threaded recesses and extending outwardly from the outer face of the ring, a second ring adapted to be secured to the first mentioned ring and having elongated slots formed therein for the reception of the shanks of said bolts and one end of each I slot having an enlarged portion for the re ception of the heads of said bolts, the second mentioned ring having an opening therein of less diameter than the opening of the first mentioned ring, the outer face of the second mentioned ring having a recess there in, a packing ring arranged within said re cess adapted to lie flush with the outer face of the second mentioned ring and having an opening therein of the same diameter as the opening of the second mentioned ring and the outer face of said rings adapted to be held in close Contact when coupled together, substantially as and for the purpose set forth.

2. In a device of the character described, a coupling comprising two members, one of the coupling members comprising a circular ring, an internally threaded flange extending outwardly from one face of said ring and adapted to be detachably connected to the discharge pipe, said ring having an opening therein of the same diameter as the opening within the discharge pipe, the opposite face of the ring having threaded recesses therein, bolts mounted within the said recesses and extending outwardly therefrom, the other coupling member comprising a ring having a threaded flange extending from one face thereof, the opposite face of said ring having a recess formed therein. a packing 'ring secured within said recess, the second coupling member having an opening therein of less diameter than the opening of the first mentioned coupling member, the outer faces of said coupling members adapted to lie in close contact when locked to gether, the ring of the second coupling member having elongated slots therein for the re ception of the shank portions of said bolts and the ring of the second mentioned coupling being held in close contact to the ring of the first mentioned coupling between the outer face of the ring of the first mentioned coupling member and the heads of said bolts.

In witness whereof, we hereunto subscribe. our names to this specification in the pres ence of two witnesses.
