To all whom it may concern.-

Be it known that I, JEFFERSON J EFFERY, a

citizen of the United States of America, re-.

siding at Newcastle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Hose-Couplings, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to means for detachably securing the sections of pipes together, and more particularly to that class of couplings employing flexible hose.

One of the objects is to provide a quickaction coupling of 'very simple construction that will permit either end of a section of hose being coupled with either endof another section or with a plug or nozzle; thereby saving time, trouble, and the'necessity of using an extra piece or reducer or the turning of sections end for end, as with male and female couplings. I

A still further object is to provide means of a simple nature which will automatically bridge the joint between two coupled members and serve to prevent leakage thereat.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein Figure 1 is a sectional view of one of the coupling members. Fig. 2 is a similar view of a coactiug member. Fig. 3 is an end elevation of one of the members. Fig. 4 is a. top plan view of the same. Fig. 5.-is a sectional view taken on the line 5 5 of Fig. 4 and showing the application of a releasingtool. Fig. 6 isadetail sectional view through the coacting coupling, showing a releasingtool applied to the same.

Similar reference-numerals indicate corre- 'ings.

In the present embodiment two members are illustrated; but as these members are duplicates but one need be described.

A tubular member 1 is employed, having a reduced outer end 2. This member is provided onone side with a longitudinally-disposed lug 8, preferably extending the length of the member and having one end projecting beyond the reduced portion 2 of said This projecting end is provided of an inwardly-extending hook. Said lug is,

furthermore, provided witha longitudinallydisposed tapering seat 6, one end of which is in communication with the groove 5. In this seat is located a latch 7, pivotedbetween its ends by a suitable pin 8. One end of the latch has an inwardly-extending bill 9, that is normally located in the groove 5, the other end being pressed against by a suitable spring 10, located in the seat beneath the same. The side of the coupling member opposite the lug 3 is provided with an outstanding transverse flangell, located at the edge of the reduced portion 2, and thereby forming an outstanding hook portion. This flange is provided between its ends and in its outer edge with a socket 12. Abutmentstops in the form of projectionslB are located upon the reduced portion 2 in rear of the flanges 11, being spaced therefrom, as illustrated particularly in Figs. 1 and 2.

In practice the members are secured to the flexible hose in any suitable manner. To couple them, it is only necessary to arrange the inwardly and outwardly extending hook portions out ofalinement and bring the ends of the members together, after which by twisting-said members so that the outstanding book of one will interlock with the inturned book of the other said members will be securely fastened together. During this movement the inwardly-extending bills 9 of the latches will aline with the sockets 12 and seat themselves in said sockets, thereby preventing any further turning of the members and-locking them against disassociation. In this connection it will be observed that the latches are entirely housed within the lugs, so that they will not be struck and accidentally operated or injured when the hose is dragged or moved. Under ordinary conditions to release the members it is only 'necessary to press the rear ends of the latches inwardly by hand, thus withdrawing the bills from the sockets, so that the members can readily be turned, and consequently separated. In freezing weather, however, the parts may become frozen together, in which case tools 14 are employed. These tools are each provided at one end with a hook 15, adapted to engage in suitable depressions 16, formed in the sides of the lugs 6. An intermediate enlargement 17 is formed upon each tool, so as to engage the latch 7, the opposite end of the tool being formed into a suitable handle and having a guide-lug 18. By applying these tools to the members, as shown in Figs. 5 and 6, not only may more power be exerted upon the latches to actuate them, but said tools also constitute levers that will assist in turning the members.

Another important feature of the invention is the means provided to prevent leakage at the joint between the members. As shown in Figs. 1 and 2, each member is provided with an internal annular rib 19, and a collar 20 is slidably mounted within the member, being provided at its inner end with an outstanding flange 21, which is arranged to engage the rib to limit the outward movement of said collar. Surrounding the outer end of the collar and suitably secured thereto is a sleeve 22, located on the side of the rib 19 opposite the flange 21 and being spaced from said flange, so that the sleeve and collar will have alimited longitudinal movement. When the members are together, the adjacent ends of the sleeve will be abutted, and as soon as water is admitted to the hose in either direction it will strike against one of the outstanding flanges 21, forming an abutment for this purpose, so that the collar will be moved longitudinally and the sleeve carried thereby will bridge the joint between the members, consequently preventing leakage. The parts are held in place by the rib 19 when the members are separated.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a hose-coupling,the combination with tubular bodies to be employed with their ends abutted, of a sleeve slidably mounted in one member and carrying a packing element in its outer end that is arranged to be projected across the joint between the members.

2. In ahose-coupling,the combination with tubular members to be coupled with their ends abutted,of sleeves fitted within the members, each sleeve being longitudinally and freely slidable within the members and either being movable into its member or capable of being projected across the joint between them and into the opposite member.

3. In a hose-coupling,the combination with tubular members to be coupled, of a sleeve slidably fitted in one member and arranged to bridge the joint between said members when coupled, said sleeve being freely movable and having an abutment portion against which the water strikes to move said sleeve.

4. In a hose-coupling, a coupling member having an inturned rib, a collar extending over the rib, and a packing-sleeve carried by the collar and movable toward and from the rib, said sleeve constituting a stop to limit the movement of the collar.

5. In a hose-coupling, a coupling member having an inturned rib, a collar extending over the rib and having a flange located on one side of the same, and a packing-sleeve carried by the collar and located on the other side of the rib.

6. In a hose-coupling, a coupling member having an annular internal rib, a collar slidably fitted within the member and having an outturned flange at its inner end, said flange being located on one side of the rib, and a packing-sleeve secured to the outer end of the collar and located on the other side of the rib, said packing-sleeve and flange being spaced apart sufificiently to permit the sliding movement of the sleeve and collar.

7. In a hose-coupling, a coupling member having a longitudinally-disposed lug provided with a seat in its outer face and a recess in one edge, and a latch pivoted in the seat, said recess being constructed to receive the fulcrum of an operating-lever for the latch.

In testimony whereof I affix my signature in presence of two Witnesses.

JEFFERSON JEFFERY.
