To all whom 'it may concern.'

Be it known that l, Josnrrr H. Kutter, a citizen of the United States, residing at West Lake, in the parish of Calcasieu and State ot Louisiana, have invented a nevv and useful Hose-Coupling, of which the following` is a specification.

One object of the present invention. is to improve the latch mechanism whereby the constituent members of the hose coupling are held together;

Another object oi the invention is to provide, in one oi the members of the coupling, an element which serves as an abutment for the hose, as an abutment for the gasket, and as a place of mounting for the securing element which holds the latch.

A further object of the invention is to provide novel means for protecting the head of the latch and for protecting the securing element which holds the latch in place.

lt is Within the province ot' the 'disclosure to improve generally and to enhance the utility of devices of that typehereinafter described. g

The drawings show a typical embodiment merely, and changes falling Within the skill of a mechanic may be made, Within the scope of what is claimed, Without departing from the spirit oli the invention. v

ln the accompanying drawings; Figure l shows in side elevation a hose Ycoupling constructed in accordance With the present invention;

Fig. 2 is a longitudinal section of the coupling, wherein parts appear in elevation;

Fig. 3 is a cross section taken on the line 3-3 of Fig. 2; and

Figs. l and 5 are cross sections taken through the complementary member of the coupling and showing the cam, part of the latch being disposed inoperative relation thereto. y

ln carrying out the present invention, there is provided a main tubular member l, equipped in its interior and intermediate its ends with an annular shoulder 2. ln front of the shoulder 2, a circumscribing groove 3 is fashioned in the main member. A resilient gasket d is mounted 1n the groove 3 and abuts against one face oi' the shoulder 2. 'in

its interior, and to the rear of the shoulder 2 the main member l is supplied vvith cireumferential ridges 5 Which serve to retain a hose 6, Within which is located an espander 7 ofany desired kind, constituting means :t'or maintaining the hose 6 engage` with the ridges 5. The hose 6 and the exI pander 7 abut against the shoulder 2 as clearly shown in Fig. 2 of the drawings. The outer end of the main member l is provided with an external annular bead 8. Outstanding parallel ribs 9 are disposed longitudinally et the main member l, and merge into the bead 8. Resilient tongues l0 lie between the ribs 9, the rear ends of the tongues being attached to the main member l by means olf securing devices il. lt is to be observed that the securing devices ll enter the annular shoulders 2, as shown in Fig. 2. These shoulders 2, therefore, reinforce the main member l to receive the securing devices 1l. Further, the outer ends or heads of the securing devices 1l are housed between the ribs 9 and lie in front of the bead S. the outer ends of the securing devices being protected in this Way, so that the securingdevices will not be likely to become dea skilled mechanic will understand that the` heads may be formed integrally with the spring tongues if desired.

The numeral 12 designates a complementary member having a reduced tubular end 16 received within the main member l and abutting against the gasket 4. The outer end of the complementary member 12 is provided externally With an annularv bead 15 which serves as a protection for the headcarrying end of the tongue l0 when the main and complementary members are locked together, as shown in Fig. 2. The complementary member l2 is supplied With an in ternal annular shoulder l? and in the bore of the complementary member, outwardly7 of the shoulder l?, annular ridges 18ers fashioncd, these ridges serving to retain a hose 19 held in place by an expander 20, the hose and the expander abutting against the shoulder 17.

A salient feature of the invention remains yet to be discussed. It is to be noted that in the outer surface of the complementary member l2, transverse notches 21 are formed, these notches defining shoulders 23, wherevvith the heads 14 of the latch tongues l() engage, to hold the main and comple mentary members of the coupling together,

gn The rear Weils 24 of the notches 21 ere curved et their ends, and merge lno the outer surface of complementer;r me1nver l2, to define cams 25. The constituent members l and of thefeoupling may he telescoped by e right line mofgement, the tongues l yielding and permitting the heads 14 to engage Vith the shoulders Q3. When it is desired to separate the members l and l2 of the Coupling, relative rotation therebetween may produced, whereupon the heads le of the latch tongues l0' Will ride irst ron to the cams L5 end thence on to the outer surface of the eompleinenter;v member 1Q, it being unneeessar)Y to pry the heeds 14 out of the notches 2l when it is desired to separate the parte oi' the coupling, Since the tongues l() more between the ribs 9, e single securing element il muy be employed for holdingl eeen tongue in place end the tongues Will. not swing on these securing elements The tongues l0 nre supplied. *l nel* ends with hooked portions 5l in. gage the tubular men'xher l and rein large amount of strain from the sec-uri" ij devices ll. The outer ends of the tongues l() are hooked es shown et 50 to engage with the he-(ids le, the strength of ,the iet/ure being correspondingly enhanced.v

Having thus described the invention, what is claimed is:`

l. A hose coupling comprising coperatng tubular members each provided with means for hold-ing e hose section lined thereto; end e spring` tongue secured to one member and provided with e.. heed, the other member having 'n transverse notch extended eir inpsi-rt wey there-around, the notch defining e' shoulder 'with which the head engages to oid sind members togethera toe rear Wall within the mein member and having e trans! verse notch defining n shoulder wherewith the bend engages to hold said members together, the rear ueli oi the notch heilig,` curved it its ends, and merging into the outer fece of the Complementary member to form eems Which disengnge the heed from the shoult er and direct the heed upon the outer 'fece of tne complementary member when relative rotation between said members is brought about, the complementary menioer having' an annular terminal bead forming n guard for the heed when the hea-d is engaged withv the .shoulderw In testimony vthat oieim the foregoing es my own, l here hereto atixed my signature in the presence of two Witnesses JGSEPH H. KELLEY.
