PATENT vEDWARD DRAUDT AND ALBERT DRAUDT, OF CLEVELAND, OHIO.

HosnncouPLlNcL SPECIFICATION forming part of Letters Patent No. 472,342, dated April 5, 1892. Application filed November 4, 1891. Serial No. l110.887. (No model.)

To all whom it may concern:

Be it known that we, EDWARD DRAUDT and ALBERT DRAUDT, of Cleveland, inthe county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Hose-Conplings; and we do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

Our invention relates toy improvements in hose-couplings, the object being to p roduce a simple, durable, and comparatively inexpensive coupling, ,and one that can be easily nianipulated.

With this object in view our invention consists in certain novel features of con-struction and in combination of parts hereinafter decribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in perspective showing the two parts of our improved coupling disconnected. Fig. 2 shows the parts of the coupling connected, one part being shown in elevation and the other part in section. Fig. 3 shows a longitudinal central section of the parts disconnected. Fig. 4 is an elevation of the spring of the locking mechanism detached.

Our improved coupling comprises a female part A and a male part B. Part A has internal (preferably annular) shoulders a a and is slotted, as at A', the slot extending from the edge of the receiving end of part A approximately to shoulder a and being contracted, as at A2, forming shoulders as as, and the slot has, preferably, a flaring mouth, being gradually increased in width from the contracted portion toward the entrance of the slot,'as shown at A3. v

Part B of the coupling has external (preferably annular) shoulders b bf and has an annular spring S mounted thereoii between said shoulders, the ends of said spring terminating in oiitwardly-projecting members S2. Spring S in its normal condition protrudes somewhat at the periphery of part B, as shown a S.

In coupling the respective parts of the coupling male part B is adapted to enter female part A, slot A of part A being adapted toreceive the outwardly-projecting members Sz of spring S,part Acoinpressing spring S against its seat between adjacent shoulders Z1 b durlock the two lparts of projecting members S of the spring, and it is.

manifest that spring S, in conjunction with shoulders c and d3 of part A, will securely the coupling together. Spring S having, preferably, at sides, as at S3, the entrance to part A should be beveled or rounded, as at a3, whereby, in conjunction with the Haring mouth of slot A aforesaid, the compression of spring S aforesaid, and consequently the coupling of the parts', is greatly facilitated.

In uncoupling the parts, by pressing members S2 of spring S toward each other with the lingers, so as to compress spring S, as required, the parts of the coupling can be readily separated.

If. the coupling is to be employed for connecting two sections of hose, an annular disk of packing (notshown) isinterposed between shoulder ct of part A and part B of the coupling; but if, as shown, the coupling is to be employed for attaching a hose to a hydrant, for instance, the packing, as at D, is interposed between shoulder a, aforesaid, and the screw-threaded port-ion of part A, that is adapted to screw onto the nozzle of the hydrant, and the forward end of part B should be adapted to lit within slioulderoJ against packing D. Hence it will be observed that in the case last referred to butone disk of packing is required to make a tight joint between the parts of the coupling and between the coupling and nozzle to which the coupling is attached.

Oui' improved coupling, it willbe'oloserved, is simple in construction, easy of manipulation, and comparatively inexpensive.

Vhat we claim is* 1. A hose-coupling comprising a male part and a female part, the latter being adapted to receive the former, the female part having internal shoulders and the male part having external shoulders, with a spring mounted tl1ercon between the said external shoulders, tlie IOO body of the spring protruding in its normal condition at the periphery of the male part, the construction of parts being such that during,r the act of coupling said spring is compressed and maintained in such compressed condition by the female part of the coupling until the interval between the aforesaid ex ternal shoulders of the male part registers with the interval between the aforesaid shoulders of the female part, substantially as set forth.

2. A hose-eonpling comprising a male and a female part, the latter being adapted to receive tlieformer, the male part having: shoulders externally and the female part having internal shoulders, the male part having a spring mounted thereon between its said external shoulders, the ends of said spring terminating in outwardly-projecting members, and

the spring in its normal condition protruding at the periphery of the male part, the female part being adapted during the act of coupling,r to compress and maintain said spring in its compressed condition until the interval between the aforesaid external shoulders of the male part have registered withpthe interval between the aforesaid internal shoulders of the female part, the female part being slotted to receive and accommodate the outwardly-projecting members of the spring, substantially as set forth.

In testimony whereof We sign this specification, in the presence of'two witnesses, this 3d day of October, 1891.

EDWARD DRAUDT. ALBERT DRAUDT. Witnesses:

C. H. DoRER, WARD HOOVER.
