TO ALL WI-IOM I'l MAY CONCERN Be it kuownthat we, MosELEY S. CURTIS and WrLLniM D. Tnwnsunr, both of the city, county, and State of New York, have invented a certain new and useful Improvement in Hose and other Couplings, of which the following is a full, c lear, and exact description, reference heilig had to the accompanying drawing, forming Vpart of this specification,and in which- Figure 1 represents a longitudinal section of a hose-coupling constructed according tio our improvement.v

Figure 2, a transverse section thereof through the line xa; and

Figure 3, a sectional plan of the female coupling through thev line z z in iig. 1.

Like letters indicate like parts throughout the several figures. -v

This invention relates to what is usually known as Gaylords hosecoupling, in which the male and female butts are so combined with an interposed'elastic packing-ring as that, by the application of force to'one side only of the coupling, said butts are drawn together or released to establish or break the connection as required, and which action is `produced by-means of a radial outside screw formed with a bevel end arranged in the one butt, and working against a bevelled ring on the other-butt, in connection with a bevelled projection opposite to the screw in the same butt as the latter, and bearing `against: the bevelled ring of the inside butt', andV the nature of our invention consists in a novel combination, with a bevelled ring or formation on the male' butt, and bevelled projection inside'tlie female butt, of a sliding bevelled-edged b1ock,voperated by a screw from the outside, and that serves toV tighten up or release the coupling without turning or guiding on'the bevelled ring of the inside butt, and withoutlongitudinal play of the screw, thereby lessening the protuberance outside of the latter. And said invention further' consists in a peculiar construction or arrangementof certain details for effecting such action. `This our invention, by a suitable modification of the butts, is applicable alike to pipe as to hose-couplings and connccting-shafts. As represented in the drawing,-it is shown as. applied to a hosecoupling. i Y

Referring to the accompanying drawing, A represents the male, and B the female butt. C is the interposed soft or elastic pacling. The male butt A is constructed with a bevelled ring or formation,'b, and the female butt with a reversely bevelled formation or partial ring, lc. Through or on the female buttB is anozzle, D, of such congurntion on the inside as to snugly receive within it, so ns to be incapable of turning therein, a square or other shaped sliding-block, E. To prevent leakage, this sliding-block may be fitted with4 a packing, d. It is bevelled on its edge, that, by means of a screw-cap,E is made to bear against the bevelled ring formation b of the male butt. The screw-cap F is provided with a screw-shank or` pin, e, that tits into afemale screw 01 thread in the block E, and so that by turning the screw-cap to the right or left, the block E is lworked radially in or out to tightenl up or release the coupling by causing its vbevelled edge to bear on or off the bevelled ring b. To effect thisA action the screw-cap F has a fixed rotation on the nozzle D, which 'may be accomplished by screwing the cap on Ato a split ring,f, fitting a groove in the nozzle, and so as to be capable of freely turning therein with the cap; a pin, s, serving to hold the cap and ring together. Another pin, g, projected through one side of the nozzle, and fitting into a groove, i, in the block, restrains the latter from being worked below a proper point orldistanc'e. l V

From this description it will be observed that as the block E does not turn in its socket, and presents a long or broad bearing on the bevelled ring of the male butt, there is no grinding action on the latter, and that a. long effective resisting surface is obtained; also, that the screw which operates the block has no longitudinal' motion whereby its protuberance or that of its cap on the outside is diminished.

What we claim as our invention, and desire to secure by Letters Patent, is-

l. lThe combination, with the bevel rings orformations and c on the male and female butts, ofthe beveledged sliding-block E, when said sliding-block is prevented from revolving, and operated by means of a screw, restrained from longitudinal play, substantially as specified.

2. The combination of the screw-cap F, screw e, and sliding-block E, for operation in connection with the butts and their bevelled rings or formations, all constructedand arranged essentially as herein set forth.
