IMPROVEMENT IN HOSE-COUPLINGS.

The Schedule referredto in these Letters Patent and making part of the same To all whom fit may concern:

Be it known that I, WILLIAMAJ. OsBoURNE, of the cityfconnty, and State of New York, have invented a new and useful Improvement in Hose-Coupling; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the'same, reference` .being had to the accompanying drawings, forming part ot' this specification.

This invention relates to a new and useful improvement iu couplings for hose-pipe, whereby the parts of the hose are united inA a more perfect manner than by theordinary hose-coupling; and

It. consists in the use of a ring or band, around one portion of the coupling, said band having upon its periphery two or more inclined planes, with which inclined planes, hooks on the other part ofthe coupling engage, as will be hereinafter more fully described.

In lthe accompanying drawin fy Figure 1 represents an outside vie'w of the coupling, with hose attached to one part.

Figuie 2 is a longitudinal section of ig.3, through the line y y.

Figure 3 is a cross-section of the coupling through the line a: a: of iig. l.

Similar letters of reference indicate correspondingparts.

faces, to which the hose is att-ached.

C represents the hose.

l D is a collar on the part B, which is secured thereon l by means of a shoulder, and by the end of the hose,

as seen in the drawing.

This allows the hose (with the part B) to be turned round freely, to relieve the hose of twist, or for other purposes. y

Attached to this collar D, are two or more hooks E.. F is a stationary collar on the part A, beneath which, and Hush with the end of A, is secured (in any suitable manner) elastic packing G, against which the end of the part B is pressed, when the two parts are coupled, as seen in tig. 2. 'There are orifices through v.A and B are metallic tubes, with corrugated surt-his collar, through which the hooks E project, as seen in iig. 1.

H is the loose ring or band, which is vplaced on the` part A,back of the collar. F.

The outer surface or periphery of this ring or band bears inclined planes, (two or more,) marked in the drawing I J, with which the hooks E engage.

K is a milled rim around the band or ring H, by

which the ring may be revolved by means of a spanner\\freuoh, or by any other suitable means.

W`Vhen the bases of the inclined planesare opposite the orifices through the collar D, the hooks will eu- 'gage with them, when, by turning the ring, the two parts of the coupling will be brought together with a constantly-increasing force, as with a screw.

Ou the outer edge of the ring there is a stop-flange,

and on the part A there is a stop-pin, which' limits the movement of the ring around the coupling, but I do not confine myself to ythis particulararrangement.

I am aware that the parts of a hose-coupling have been before united by means ot' inclined planes, but I am not aware 4that such inclined planes have been confined to a band or ring, haring a motion independent of the hose or parts of the coupling, which arrangement allows the parts of the hose to be turned in any manuel, ,without in the least disturbing the Witnesses GEO.
