HOSE-COUPLING.

Specification of Letters iatent. I Patented July 28, 19 14;

Application filed. July 29, 1912. Serial No. 712,192.

means for connecting the inner, member ofv the coupling with the outer member thereof, the construction being such that the members may be separated only when first forcibly thrust together, the members being then drawn in opposite directions.

A further object of the invention is to provide a novel form of jaw, adapted to interlock with the inner member, and to provide a novel form of spring means for actuating the jaw.

lVith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings,-Figure 1 shows the invention in longitudinal section; Fig. 2 is a side elevation; Fig. 3 is a top plan; and Fig. 4 is a detail enlarged from Fig. 1.

In carrying out the invention, there is provided an outer member 1 provided with a flaring mouth 2, the mouth 2 being provided in its interior with one or more packing rings 3. The inner member is denoted by the numeral 4 and includes a conical head 5, adapted to fit within the flaring mouth 2 of the outer member 1, the head 5 being surrounded by one or more packing rings 6. The head 5 at its outer end is equipped with a flange 7, defining a recess 8.

The outer member 1 is circumscribed by a reinforcing band 9 having spaced pairs of cars 10. Connecting the ears 10 of each pair is a pivot pin 11.

Jaws 12 are shown, the jaws terminating in transverse, curved heads 14, adapted to extend part way around the innermember 4, and to bear thereagainst." The innerfaces of the heads 14 of the jaws 12 are/flared as indicated at 15, so asto receive, initially, the cone-shaped head 5 of the inner member 4. The inner edges of the heads 14 are equipped with flanges 16, defining recesses '17. The flanges 16 of the heads 14 overlap the flange 7 of the head 5, the flanges 16 registering in the recesses 8, and the flange 7 registering in-the recesses 17. The jaws 12 are curved to formbearings '18 which sur-' vround thepins 11, between the ears 10.

Actuating springs for the jaws 12 are provided, the springs comprising diverging arms 19 united by curved connecting portions 20 which bear against the heads 15 of the jaws 12. As indicated at 21, the arms 19 are curved around the pivot pins 11 upon the outside of the cars 10, the pivot pins 11 belng equipped terminally with heads 22 which engage the curved convolutions of the 1 arms 19 and hold the same upon the pivot pins. Beyond the pivot pins 11 the arms 19 of the springs are prolonged to form extensions 23 having terminal, angularly. disposed fingers 24 which bear againstopposed portions of the outer member Presupposingthat the parts 1 and 4 are separated, the operation of the device is as follows. The cone-shaped head 5 of the innor member 4 is inserted into the flaring portions 15 of the jaws 14, effecting a separation of the jaws.

If the parts 1 and .4 be drawn Ultimately, the head I 5 of the inner member 4 willenter the flarwith the member 4, by the action of the springs 201923. When it is desired to separate the membersl and 4, the members will telescope beyond the position shown in Fig. 1, the yieldable packings 3and6- per mitting such telescoping; When the parts are telescoped, the flanges 7 and 16 of the inner member 4 and of the jaw heads 14,

respectively, will move longitudinally out of engagement, whereupon the jaws 12 14 may be swung laterally upon their pivotal mountings 11, so that the flanges 16 of the jaws lie beyond the flanges 7 of the inner member 4. Thereupon, as will be obvious,

the inner member 4 may be withdrawn, the

the members 1 and 4 be thrust toward each other, the coupling cannot fall apart accident-ally, owing to the fact that the jaws l214; are thrust against the member 4: by

the action of the springs.

Having thus described the invention, what is claimed is A pipe coupling comprising a member with a flared conical mouth, a second member provided with an enlarged conical head, the obliquity of the conical surfaces of the first and second mentioned coupling members being the same, a rearwardly extending flange carried by the second mentioned coupling member at the rear portion of the head i thereof, the first mentioned coupling member provided with upstanding spaced ears,

ond coupling members allowing for limited axial movement after a sealed joint has been effected therebetween, resilient springs carried by the said upstanding ears of the first mentioned coupling member engaging the first mentioned coupling member and the said semi-cylindrical ends of the locking arms, holding the same against radial movement.

In testimony whereof I aflix my signature in presence of two witnesses.
