To @ZZ whom it may concern:

Be it known that I, ROBERT M. DIXON, a citizen of the United States, residing at East Orange, Essex county, State of New J ersey,have

` dercut lug or engagement member "e.

invented certain new and useful Improvements in Hose-Couplings, of which the following is a specification.

My invention relates to hose-couplings, and has for its object to produce a hose-coupling which may be readily coupled and uncoupled.

In the accompanying drawings I have shown a coupling in which one form of my invention is embodied.

Inthe drawings, Figure I is a plan View of 1 the coupling. Fig. II is aside elevation; and

Fig. III is an end elevation, of the coupling looking from right to left in Fig. I.

In the drawings, a represents the couplerhead, herein shown as provided with a straight port and with a gasket 'c seated therein. A ribbed side arm or bracket d is provided at the sideof the coupler-head, carrying an un- This lug or engagement member e is adapted to engage with another undercut lug orengagement member f at the side of the body of a corresponding coupler-head.

In order to provide means whereby the couplerheadsmay be readily engaged one with the other, 'I have provided a fulcrum-lug g. This lug is shown in the present instance as having a curved or inclined face and as located at the lower 'edge t of the coupler-head on the side next the side arm d and integral with the said coupler-head. This lug g is shown as extending less than half of the width of the coupler-head, and the arin Z is shown as of greater depth than the height of the coupler-head, by which I mean the rectangularfaced portion shown in Fig. III.

It will be obvious that when thev couplings are put together. in the usual manner. the

lower edge 71. of each coupler-head will rest upon the curved or beveled facet' of the lugs g, so that the lug will not only form a bearing or fulcrum for the swinging movement of the coupler-head, but by reason of its curved or inclined face t' will serve to guide the coupler-heads into their ultimate positions.

It will be observed that the face t' of the lug g is shown convexly curved throughout its entire extent, there being no concave portion thereof whatever.. In Fig. II it is shown as curved from front to rear, and in Fig. III it is shown as laterallycurved from the lateral edge g. o I am aware that it has been proposed to form a coupler with a rib extending substantially half the width ofthe coupling with a recess extending the remaining haltI of the 4width of the coupling, such as is shown in patentto Beery, No. 494,316, March 28, 1893, and I do not herein claim such a construction. The construction which I have described, which I shall hereinafter claim, constitutes not only a fulcrum for the swinging movement made when the parts are ycoupled together, but also constitutes a guide for bringing the parts together with certainty and in this sense, among others, is distinguishable from the construction herein'disclaimed.

VHaving described my invention, what I claim, andhdesire to secure by Letters Patent, Isf 1.- The combination of a coupler-head having a side arm d pi'ovided with a lug or engaging means e and a lug ory engagement means f on the coupler-headand a combined fulcrum bearing and guiding lug g having an inclined face located at the lower edge of the coupler-head ct.

y 2. The combination o f a coupler-head and. side arm provided with reciprocal locking means of a guiding and fulcrum lug g having an inclined face and adapted to serve both as a guide for guiding the coupler-head into its coupled position and as a fulcrum for, the coupler-heads, the said lug being located at one side ofthe median line of the coupler-head.

3. The combination of a coupler-head,means for securing the same .to a compleinentallyformed coupler-head, anda side lug g located at the lower edge of the coupler-head, the said lug g having an inclined face adapted to serve as a guiding and bearing surface for the lower edge of a. complementally-formed couplerhead.

4. The combination in an integral construction of a coupler-head a, a side arm or bracket d and a lug g Serving to guide the couplerliead into its coupled position, the said lug g being integral with the coupler-head a and the side arm 0l and located at the junction of the coupler and side arm.

5. The combination in an integral construction of a coupler-head ce, a side arm or bracket (l and a, lug g, the said lug g being integral with the coupler-.head a and the side arm d at the junction of the coupler-head and side arm, the said side arm extending below the said coupler-head and the-said lug forming a lateral prolongation oi' the said side :L1-m.

6. The combination of a coupler-head and a side arm each having complerncntal coupling means, of a combined guiding and fulcrum lug at the operating-face of the coupler-head, the said lug serving to guide the coupler-heads together when coupling saine and also serving as a fulcrum.
