COUPLING.

' Specification of Letters Patent.

Patented Oct. 15,1912.

To all whom it may concern:

Be itknown that we, ALBERT O. GALE and ELDoR J. IvnRsoN, both citizens of the United States, and residents of Seattle, in the county of King and State of VVashington, have invented certain new and useful Improvements in Couplings, of which the following is a full, true, and exact specification.

The principal object of this invention is to provide simple, effective and quick acting means for coupling together the ends of hose, line shafting, or the like, and in the operation of which no wrenches or other tools are necessary.

Referring to the accompanying drawing, Figure 1 is a side elevation of our device in locked position. Fig. 2, an end elevation of the same. Fig. 3 is a central longitudinal sectional view of Fig. 1. ,Fig. 4-, a side ele vation of the righthand locking member. Fig. 5, a side elevation of the corresponding lefthand member. Fig. 6, a side elevation of the collar, partly in section. Fig. 7 a side elevation of the cap, partly in section. Fig. 8, an end elevation of Fig. 7, looking toward the left. Fig. 9, a side elevation of the two principal locking members in locked engagement of each other, and stripped of the other parts. 4

Referring now more particularly to the drawings, the numeral 1 designates a central core which, if the coupling be used for hose, may be hollow, as shown, and to the lefthand end of which may be attached in any suit-able manner, one of the sections of hose to be coupled. Around the outer surface of the core 1, and firmly secured thereto, are the oppositely disposed curved plates 3, projecting from which are the studs 4. The righthand end of the core 1 is tapered as at 5.

6 designates a collar, having the annular knurled rib 7 annular groove 8, and cam slots 9. From the internal surface of the collar 6, and extending toward the center thereof, are the oppositely disposed raised portions 10.

11 designates a cap which is bored to fit the lefthand end of the collar 6, and in which are the screws 12, which fit and wipe around in the annular groove 8 of the collar 6. The end of the cap 11 is counter-bored as at 13, to fit the core 1. Extending from the end of the cap 11 are the tongues 13*.

14 is the righthand locking member,

outer end of which may be suitably connected the hose to be coupled, and, for convenience in handling may have the annular rib 15.- Extending from the lefthand end of the locking member 14 are the oppositely disposed shell-like projections, 16, which are substantially counterparts of the plates 3, of the core 1. The plates 3 and the extensions 16 are of equal thickness and repwhich may be bored as at 14 and to the resent arcs of the same circle,rthe former adapted to enter the spaces between the latter (Fig. 9).

If Fig. 3 be considered especially in conmotion with Fig. 9 it will be seen that the co-re 1 and the righthand locking member 14, when in the positions there shown, can have no rotary movement with relation to each other, the projections 16 ofthe righthandlocking member 14, the tongue 13 of the cap 11 and the plates 3 of the core 1 being substantially in contact with each other, and encircling the core 1; neither can longitudinal movement occur, the same being prevented by the engagement of the studs 4 with the slots 9 of the collar 6. If either the core 1 or the righthand locking member 14 be now held against rotation and the knurled rib 7 upon the collar 6 turned in the direction of the arrow, Fig. 2, until the studs 4 reach the offsets 17 in the slots 9, the core 1 and the member 14 may be drawn apart until arrested by the contact of the studs 4 with the righthand edges of the slots 9, when the rotation of the collar 6 may be continued until again arrested by the contact of the studs 4 with the ends of the slots 9. During this entire rotation the slight cam action of the slots 9 upon the studs 4 has forced the collar 6 and its cap 11 together with its tongue 13 toward the left, withdrawing the free ends of the latter from between the plates 3 of the core 1 and the projections 16 of the member 14, so that the member 14 and the core 1 may be rotated with relation to each other sufficiently to bring the plates 3 and the projections 16 into such position as to entirely clear each other and allow the core 1 and the member 14 to be completely separated. If the operation just described be now reversed it is obvious that the coupling may be returned to its locked position.

The raised portions 10 are concaved to fit the cylindrical surface of the core 1, and are of equal thickness with the plates 3, but are upon the cylindrical surface of the core not of sutficient width to interfere with the movement of the core 1 just described; I their function being merely to form a wider bearing for the inner surface of the cap 6.

than would otherwise exist.

From the foregoing description it will be seen that we have provided acoupling easy of manipulation, sure in its action and which may be applied to hose, line shaft-' ing, or other like elements with equal efficiency, and that no wrenches or other tools are necessary to couple or uncouple the same.

We are fully aware that many minor changes in the details of construction and arrangement of the parts will readily suggest themselves to others skilled in the art, without departing from the spirit and scope of our invention, and we do not, therefore, desire to be limited to the exact form of embodiment herein shown and described.

Having described our invention, what we claim as new, and desire to protect by Letters Patent of the United States, is,.

A coupling comprising a pair of cylinders, one of which cylinders is provided with a Copies of this patent may be obtained for five cents Washington, D. G.

conical end portion and with locking plates dly and ym etr a y di pcs thereon, said locking plates having each a radially projecting stud, and the other of which cylinders is provided with an end adapted to fit the cone shaped end portion of said first named cylinder to make a fluid tight joint therewith and further provided with looking projections adapted to engage with said locking plates of said first named cylinder, and a collar having cam-slots and disposed on said first named cylinder which camslots are adapted to cooperate with said studs to forcibly engage said locking projections with said locking plates to rigidly unite said cylinders, in combination with an annular cap associated with said collar and with said first named cylinder, said cap having longitudinally extending tongues adapted to prevent rotary movement of one of said cylinders with respect to the other.
