Applicationfiled June 17,1903- Serial No. 161,946. ill'o modali To all whom it may concern:

Be it known that I,- LmvILLE V. Lone, a citizen of the United States, residing at Bowerston, in the county of Harrison and State of Ohio, have invented a new and useful .Hose- Coupling, of which the following is aspecifi catiom The invention relates to improvemfents'in hose-couplings.

The object of the present invention is to improve the construction of hose-couplings and to provide asimple, inexpensive, vandeflicient one of great strength and durability in which the parts will always-be in proper position to enable a hose to be readily coupled without turning or twisting the lengths thereof.

'A further object of theinvention is to provide a hose-coupling which will enable hose to be rapidly coupled and uncoupled and which will permit the same to be dragged over streets, curbing, fences, andother obstruc-.

tions without liability of becoming accidentally uncoupled It is also the object of the invention to provide a hose-coupling adap to exert a direct pull on its sections, to preve tany binding or frictional contact of the sections on each other,

and the consequent resistance \to such move.- ment, and capable of enablingaSteam, water, and air tight joint to be readily made. With these and other objects inview the invention consists in the construction and novel combination and arrangement of parts hereinalfter fully described, illustrated in the accompanying drawings, and pointed out in the itbeing understood that various changes in the form, proportion, size,: and minor details of construction within the scope of the claims may be" resorted to with-' out departing from the spirit or sacrificing any of the advantages of the invention In the drawings, Figure 1 is a side elevation of a hose coupling constructed in accordance with this invention, the parts being shown locked in full lines and unlocked in dotted lines. Fig. 2 is a longitudinal sectional View.

Fig. 3 isa transverse sectional view on the line 3 3 of Fig. 2. Fig. 4 is adetail ,perspectiveview of the locking mechanism.

Like numerals of reference designate corresponding parts in all the figures of thedraw- 1 and 2 designate sections preferably constructed of cast malleable iron or other suitable metal and provided with outer portions 3'and 4 adapted 'to receive hose in theordinary manner, and these outer portions may be smooth, as shown in theaccompanying drawings, or they-may be corrugated or provided with dull threads to prevent the hose from slipping. Any means may be employed for securing the hose to theouter portions 3 and def the sections. j

' The section 1 is provided with a smooth inner portion 5, which is adapted to fit into the adjacent inner portion 6v of thesection 2,'and the'latter is enlarged, as shown, to receive the shoulder 7. The exterior annular shoulder 7 is inwardly beveled'or undercut, as clearly a curved yoke 8, which conforms to the con-' section-'1 and to provide'an exterior annular shown in Fig. 2, to receive and interlock-with figuration of the section 2 and which is beveled at its inner engaging edge 9 to fit the ,beveled or undercut portion of the section 2. "The yoke is rigidly secured toa pair .of side bars 10, which are pivoted to the sides 11 ofa forked or bifurcated operating-lever 12. The

sides of the forked or bifurcated operating.-

-lever 12 are adapted to straddle the section 1 of the coupling, andthey are piv'oted'near their outer ends by rivets 13 or other suitable fastening devices to a collarl ig The sides 11' of the forked or bifurcated lever form short outer arms 15, which are-pivoted to theadjacent ends of the side bars 10 by rivets-16 or other suitable fastening devices.

"Thecollar 14 which is, arranged tion 1 of the coupling, -i s adapted to rotate freely thereon to enable any adj ustment of the on the sec-- looking mechanismto be effected Withoutturn: ing'or twisting the hose. The collar is ar-,

ranged contiguous to an annular enlargement- 17 locatedbetwee'n the ends of the section 1 and provided with an annular groove 18, re-' ceiving the engaging portions of-a pair of L- "shaped arms 19. The L-shaped arms 19, which are located. at diametrically opposite points,

are secured by screws 20 orother suitable fastening devices to thecollar, and they ex tend over the adjacent portion of the annular enlargement and project into the annular groove thereof. collar is swiveled onthe section 1 and is adapted to rotate freely. Instead of swiveling the collar to the section 1 by means of the L- shaped arms suitable stops, such as set-screws or the like, may be mounted on the section 1 at the outer side of the collar to confine the same in'its positioncontiguous to the annular enlargement.

The lever when viewed in side elevation is approximately sigmoidlycurved, as illustrated in Fig.2 of the drawings, to enable the outerportion to lie close to the coupling when the parts are locked and to present a smooth exterior to enable a hose to be dragged along a street, over curbs, and rough places without liability of accidentally unlocking the sections.

.The coupling will permit a hose to be dragged over fences and to be handled similar to an ordinary hose with threaded couplings without liability of becoming accidentally unfastened. The outer portion of the lever forms a grip or handle, and the curve thereof may be increased, if desired, sufficiently to enable the fingers of the operator to he introduced between the handle and the coupling.

The lever and the yoke are adapted to exert a direct longitudinal pull on the sections which are drawn together, a rubber gasket or washer 2l being interposed between the intermediate annular enlargement 17 and the end of the section 20f the coupling. One or more rings or washers may be employed, and these may be of any desired size to secure the desired joint.

The sections are readily uncoupled by simply swinging the operating lever from the position illustrated in full lines in Fig. 1 to that shown invdotted lines, and in coupling the sections the yoke is first arranged in the groove 22 between the shoulder 7 and an enlargement 23, and theleveris then swung forward or inward against the coupling to the position shown in full lines in Fig.1.;-

' What I claim is 1. A coupling comprising two sections, one

:of the sections being provided with an annula'r shoulder, and the other having an annular By this construction the,

enlargement, a collar arranged on the section having -the enlargement and capable of rotation, said collar being provided with means for interlocking it with the said enlargement, a lever carried by the collar, and a yoke connected with the lever and engaging the shoulder, substantially as. described.

2. A coupling comprising two sections, one of the sections being provided with a shoulder and the other section having an annular enlargement, a collar arranged on the latter section and provided with arms interlocked with the said enlargement, a lever fulcrumed on the collar, and a yoke connected with the lever and engaging the shoulder, substantially as described.

3. A coupling comprising a section provided with an intermediate annular enlargement hav ing an annular groove, a collar fittedon the said section at the outer side of the enlarge" mentand provided with Lshaped arms engaging the groove, a leverfulcrumed on the collar, a yoke connected with the lever, and a section having a shoulder for engaging, the yoke, substantially as described.

4. A coupling comprising the section 1 having an exterior annular enlargement provided with an annular groove, the section 2 enlarged to receive the section 1 and to form a shoulder,-

a collar arranged on the section 1 and provided with means for engaging the said groove, a lever fulcrumed on the collar, a yoke connected with the lever and engaging the said shoulder, .and a packing-ring or washer interposed between the section2and the enlargement of the section 1, substantially as described.

5. A-coupling comprising two sections, one ofswhich is provided with a shoulder and the other having an annular enlargement,a rotatable collar arranged on the latter section and provided with arms interlocked with the said enlargement, a yokeengaging the shoulder on the other'section, and. means connecting the yoke to the collar, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

' LINVI LLE v. LONG.
