Improvement in Hose-couplings.
1, ALDEN LEE BAILEY, of St. Johnsbury, State of Vermont, United States
of America, Merchant, do hereby declare the nature of this invention, and in what
manner the same is to be performed to be particularly described and ascertained,
in and by the following statement :-
This invention relates to steam or water hose-couplings, in which one section is
a duplicate of the other. The invention consists broadly in the retractile coupling
tongues, and in the means for tightening the saine, as clearly illustrated in the
accompanying drawings, of which,―
as when
Figure 1, is a longitudinal section, showing the hose-sections in position ready
to be coupled Figure 2, is a similar view showing the sections
coupled :
Figure 3, is a cross section
Figure 4, is a detail of the threaded collar which receives the coupling-
tongues.
A-A, are coupler-sections, to which the flexible hose may be attached in the
ordinary manner. B-B, are sliding collars having each a pair of tongues b-b
formed integral with and projecting from said collars at points diametrically
opposite; the outer surface of said tongues being on a plane with that of said
collars, while their inner surface is of a larger diameter than the bore of said
collars, thus forming a shoulder b', as shown.
The diameters of the outer surface of the coupler-sections vary, as will be seen
at a, a', and a; that shown at a, forms a bearing for the collars B-B, that shown
at a', forming a stop for limiting the forward movement of said collars, while
that shown at a², forms a bearing for the tongues 6--b, as well as a stop for the
forward end of a spring C, which is made of helical form and mounted (one on
each of the coupler-sections) underneath said tongues, and bearing at its other end
against said collars. By this means the coupler-tongues, which otherwise would
be constantly exposed to the danger of being broken, or bent, from careless
handling, are for the most part normally drawn in, and back of the uniting faces
of the coupler-sections A-A, which when disconnected, thus present a smooth
surface. A stop collar D is secured to each section A, which limits the movement
of the collars B, and secured thereon with a limited amount of play both
longitudinally and rotatively, as shown in Figures 1, 3, and 4, and an annular
groove e, is formed in its interior near its outer end, and slots e', connecting said
groove with the outer end of said sleeve.
:
These slots, are placed at point sdiametrically opposite in the end of each
sleeve, and form a passage-way for the projections 6, (of either tongue 6,) to
effect an entrance to the groove e.
In order that the sleeves E, may be moved
sufficiently in a rotative course to carry the projections 62, of the coupling tongues
past the slots e¹, so that they shall be retained in the groove e, said sleeve is
inovably attached to the collar B, by means of one or more pins 6, placed in
both sections A, at the proper point to enter a corresponding number of slots e,
which are made slightly wider than the pin, in order to facilitate the entrance and
movement of the said projections 62, in said groove e. An adjusting nut F, having
a flange f, at its rear end, is threaded to fit the sleeve E, and alter placing the
sections A-A face to face, said nuts are drawn towards each other, which
operation enters the tongues of each section, into the coupling ring or sleeve E, of
the other section, and then, by giving said nuts a slight turn in opposite directions,

page_text: the sleeve E, is thus rotated sufficiently to catch the projections 62, of the tongues,
in the grooves e, and the further rotation of the nut F, by the action of its
flange f, against the end of the collar B, causes the coupling-sleeves E, to move
backward or in a direction away from each other, thereby drawing the gaskets S,
of the coupler-sections closely together. The spring C, may if desired, be
omitted and the collar B, rigidly secured to the coupler-section with the tongues b
extending the proper distance beyond the face of the said sections, but I prefer
construction in which the tongues - shall be normally out of danger of
accidental injury.
a
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,―
1. In a hose coupling composed of duplicate parts or sections each section
being provided with tongues having projections on their outside, a longitudinally
and rotatively movable sleeve having an internal annular groove near its outer
end and slots connecting said groove with said outer eud, said sleeve being
provided with external threads and a nut threaded thereto, and having a flange
at its rear adapted to bear against a suitable shoulder for making a tight joint of
said coupler-sections.
2. In a hose coupling composed of duplicate sections, each section being
provided with retractile tongues having projections on their outside, said tongues
being normally flush, or nearly so, with the coupling face of said sections, a
longitudinally and rotatively movable sleeve having an internal annular groove
near its outer end, and slots connecting said groove with said outer end for the
entrance of the tongues of either section, said sleeve being provided with
external threads, and a nut threaded thereto having a flange at its rear end
adapted to bear against a ring or collar from which said tongues project, and a
ring or collar adapted to limit the rearward movement of the tongues, all
substantially for the purpose set forth.
3. In a hose coupling composed of duplicate sections, suitable spring actuated
coupling tongues having a limited movement, a longitudinally and rotatively
movable sleeve mounted upon said tongues, having an internal annular groove
near its outer end for the entrance of the tongues of either section, and a nut
threaded to said sleeve and having a flange at its rear adapted to bear against
said spring-actuated coupling tongues, substantially for the purpose specified.
