HOSE COUPLING Filed July 19, 1930 mVENoR.
foH/v F CANTELL A TTORNEYS.
Patented Jan. 12, 1932 PATENT OFFICE JOHN F. CANTELL, OF SAN FRANCISCO, CALIFORNIA HOSE COUPLING Application filed `Tuly 19,
My invention relates to improvements in hose couplings, and it consists in the combinations, constructions and arrangements hereinafter described and claimed.
An object of my invention is to provide a hose coupling Which is leak proof and in which the parts may be merely pressed together for causing them to Vbe automatically connected one to the other. The coupling in provides a liquid-tight connection for the hose itself, and provides a `further liquidtight connection for the casing enclosing the operating parts.
A further object of my invention is to pro- ?.i vide a device of the type described Which is simple in construction and durable and eilicient for the purpose intended.
Other objects and advantages Will appear as lthe specification proceeds, and the novel 20 features of the device will be particularly pointed out in the claims hereto annexed.
My invention is illustrated in the accom-y panying drawings forming a part of the application, in Which:
Figure 1 is a longitudinal section through the device,
Figure 2 is a section along the line 2 2 of Figure 1,
Figure 3 is a section along the line 3-3 of Figure 2, and
Figure 4 is a side elevationof the device. y
In carrying out my invention I provide a tubular member 1 having a recessed end 2 for receiving a male portion 3 of a tubular member 4. The member 4 has a conical-shaped portion 5 provided With a shoulder 6.
VOn the member 4 I mount a casing 7 that A has a bevelled edge 8 designed to be received in a bevelled portion of a casing 9, the latter being carried by the member 1. The tubular members When connectedtogetlier cause the casing 7 and its edge 8 to form a fluid-tight closure for the fastening means.
Reference to Figure 1 shows the member 1 as carrying fork-shaped supports 10 that and is guided by a guide member 32.
1930. Serial No.v 469,174.
have pins 11 slidably received in slots 12. The slots are formed in levers 13 that in turn have trigger-shaped ends 14 for riding over `the conical portion 5 and engaging with the annular shoulder 6. Other supports 15 simi- Vlar to the supports 10 have pins 16 that are slidably received in slots 17, the slots being disposed in levers 18.
The levers13 and 18 are pivotally connected together at'19 and also bear against a plunger which is slidably received in a sleeve 21 carried by the casing 9. The plunger 20 has an enlarged portion 22 that normally seats against the inner end of the sleeve 21 and prevents the passage of fluid through the sleeve.
The levers 13 and 18 are yieldingly held in the position shown by a piston 23 slidably mounted in a cylinder 24 and yieldingly held in its outermost position by a spring 25. The piston has a projection 26 that bears against the levers 13 and 18 at their point of connection19 and holds the levers in the manner shown in Figure 1.
In Figure 3 I show how each piston 23 is provided with a guide slot 27 that receives a pin 28. A bayonet slot 29 communicates with the slot 27 and permits the piston to be assembled in position. The slot 27 limits the movement of the piston.
In Figure 4 I shoiv the plunger rods 2O as projecting beyond the casing 9 and as riding on cam portions 30 of a forked member 31. The latter member is slidable longitudinally A bell crank lever 33 pivoted at 34 has a pin and slot connection indicated generallyl at 35 with the member 31. It will be seen that a depressing'of the arm of the lever 33 Will move the member 31 for moving the plungers 20 toward each other. This movement causes the levers 13 and 18 to fulcrum about the pivots 11 and 16 and to free the triggers 14 from lthe shoulder 6. The casings 7 and Qmay noW be disconnected from each other.
In securing the device together, the members l and 4 are moved into engagement with one another, and this movement causes the triggers 14 to engage with the shoulder 6 and the casings 7 and 9 to form a liquid-tight compartment. The parts are h eld in this position by the springs 25. If desired, the member 4 may be rotatably secured to a hose 36 (see Figure l) by a swivel 37 that permits the device tovbe rotated with respect tothe Y hose-36. It will be noted that no threading action is necessary for connecting the parts of the coupling together, and that a liquidtight joint is provided by the connecting of the tubular members l and 4 and the casings 7 and 9. Y.
Although I have shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes, and I reserve the right to em- Aploy such changes as may come within the scope of the claims hereto annexed.
I claim: c 1. In a hose coupling, a casing, catches for lsecuring two hosesections together, plungers for moving the catches and extending beyond the casing, said plungers having enlarged Y `portions for sealing the casing openings receiving the plunger, and spring pressed pistons operatively connected to the catches for yieldingly holding the catches in closed position. f
\ 2. A hose coupling comprising a; tubular member having a conical recessv in its end, a second tubular member having a 'coneshaped end designed to enter the recess, an
annular shoulder carried by one of the members and having a conical-shaped portion, catches carried by the other member* for engaging with the shoulder, spring pressed pistons for moving the catches into closed position, ka two piece casing, plungers for moving'the catches and extending through the casing said plungers having enlarged portions or sealing the casing openings, one piece of the casing being carried by one of the members and the other piece-by the other member, said pieces Jforming a liquid tight seal when abutted together, andmeans carried by the outside of the casing for actuating the plungers.
3. A coupling comprising two tubular members designed to contact with each other and Vform a continuous passage, an annular shoulder carried by one of the members, hooks for engaging with the shoulder and being pivotally and slidably Vcarried by the'other member, spring pressed pistons operativelycon- V nected to the free ends of the hooks :tor-moving them into closed position, and means for limiting the outwardmovement of the pistons. f i
4. A coupling comprising two tubular mem- Y:bers designed to contact with each otherand form a continuous passage, an'annular'shoulthe pistons.
