HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 242,564, dated June 7, 1881.

Application flied February a, 1881. (Model.')

To all whom it may concern:

Be it known that I, LOUIS H. SHOLDER, of Cleveland, in the county I of (Juyahoga and State of Ohio, have invented certain new and useful Improvements in Hose-Couplings and I do hereby declaredhe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawi'n gs,

which form part of this specification.

My invention relates to hose-couplings; and it consists in so constructing a hose-coupling that it can be manufactured much cheaper and at the same time be just as serviceable in every respect as any of the more expensive ones now in use. It is also much more easily manipulated, and can becoupled in an instant without the use of a wrench or any like tool.

In the drawings, Figure 1 is a longitudinal sectional view of my coupling, having screwthreads formed on the male and female parts to adapt them to beattached to the common screw-coupling now in use. Fig. 2 is a longitudinal sectional view of my coupling, showing it attached directly to the hose. Fig. 3 is a plan view, showing the openings of the female part of my cou iiling; and Figs. 4 and 5 are isometric views of the male and female parts, showing them in position tobe coupled.

Like letters of reference represent corresponding parts in the several figures.

A represents the male part of my coupling, and is provided with lugs a, and also spigot b and shoulder c. As shown in Fig. 1, in some cases I provide thispart with afemale thread, which corresponds with the male thread of the common scrmvcoupling, so that it may be readily attached to hose having said male screw part.

B represents the female part of my coupling, which is provided with openings 63 and inclines c, said inclines being roughened. f is an annular rubber packing. It will be seen by reference to Fig. 1 of the drawings that I also provide this part with a screw-thread adapted to correspond with the female thread of the common screw-coupling, so that it also may be readily attached to hose having said female screw part.

The operation ot niy device is as follows:

The male part A of my coupling is attached to one end of a length of hose, either directly, as shown in Fig. 2, or by means of the male part of the common screw-coupling, as the case may be. Ihe female part B is attached to one end of the length to be coupled with the first length, either directly, as shown in Fig. 2, or by means of the female part of the commonscrew-coupling, as shown in Fig. 1.

Now, to couple thcparts the lugs a arebrought opposite the openings d, which are large enough to admit them. After being entered the parts A and B are turned in opposite directions, and

the lugs a coming in contact with the inclines c, said inclines bring the shoulder 0 against the packing f, which, being pressed tightly between shoulder c and its seat on the female part of the coupling, forces it against the outer circumference of spigot I), and also the inner circumference of the female part of the coupling, thus forming a perfectly tight joint.

It will beseen that I have provided the inclines c with roughened faces. My reason for this is to keep the lugs a from slipping back after being once turned in place upon said inclines, the rubber packingserving to force the sharp side of the lugs atightly againstthe said roughened face of the incline and hold it there. v

It will also be seen that my coupling can be manufactured much cheaper than many now in use, as the only work on them after they are cast is to clean them, the annular rubber packing, when compressed between the shoulder cam]. its seat in the female part of the coupling, filling every irregularity of the surfaces with which it comes in contact, and hence forming a perfectly tightjoint.

What I claim isk 1. A hose-coupling, the same being provided on its male portion with lugs a and on its female part with inclines c, said inclines having a roughened face, substantially :as described.

2. In a hose-coupling, the combination of the male part A, with its lugs a, shoulder c, and spigot 11 of the female part, said female part being provided'with inclines c and washer f, substantially as described.

3. A hose-coupling substantially as described, one part of said hose-coupling being 'screvmhreaded in such a manner that it may to this specification in the presence of two subbe at ached to the male part of the common scribing witnesses. 1

scre -e0upling, and. the other part; being adapted to be attached to thefemale part of said common screw-coupling, substantially as Witnesses:
