IMPROVEMENTS IN THE CONSTRUCTION OF UNION JOINTS FOR HOSE PIPES
Year: 1877

page_text: LETTERS PATENT to John Morris, of Salford, in the County of Lancaster, for
the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF UNION JOINTS
FOR HOSE PIPES."
Sealed the 11th May, 1877, and dated the 16th March 1877.
PROVISIONAL SPECIFICATION left by the said John Morris at the Office of
the Commissioners of Patents on the 16th March 1877.

CONSTRUCTION OF UNION JOINTS FOR HOSE PIPES."
"IMPROVEMENTS IN THE
This Invention is designed principally for forming hose pipes such as are used
in connection with fire-engines, but it is also equally applicable for joining or
connecting flexible and other pipes used for the transmission of liquids or gaseous
fluids.
The Invention consists principally in dispensing entirely with the screw thread
usually employed for connecting the two parts of the joint, and in so constructing
and arranging the parts that the junction is completed by merely thrusting one
part into the other without any screwing or turning action whatever.
The improved union joint consists mainly of two short cylindrical parts, each of
which is attached by tying, binding, or otherwise, in the usual manner to the end
of its respective length of hose; one part is made of a smaller diameter than the
other, so that it can pass inside the mouth of the other, as usual, but their surfaces
are merely cylindrical and not tapped with a screw thread as heretofore.
The inner or smaller part has near to its end a circular or annular groove formed
in its outer circumference, and the outer or larger part is provided with two corre-
sponding spring bolts projecting inwards and having the outer side bevilled.
When the smaller part of the joint is pressed forward into the larger the end of
the smaller part presses against these bolts, forcing them outward until the annular
groove comes opposite to the bolts, when the springs force the latter forwards into
the annular groove and the two parts become locked together.
The spring bolts work through two lugs or projections on the outer or larger part
of the joint, and their external ends are provided with knobs by means of which
the bolts can be withdrawn when it is desired to separate the two parts so as to
disconnect the hose pipe.

page_text: In order to make a water-tight or air or gas-tight joint a ring of india-rubber
is let into an annular recess in the inside of the larger or outer part of the joint,
and the end of the inner or smaller part beds against this ring as it is forced into
the other part. The ring is also provided with two annular lips, which, when there
is any pressure of water or other fluid inside the pipe, becomes forced outwards and
assists in making a good joint.
It will be evident that this construction of joint is also equally applicable for
joining flexible hose on to fixed stand pipes, pumps, or taps, and for other similar
purposes.

CONSTRUCTION OF UNION JOINTS FOR HOSE PIPES."
"IMPROVEMENTS IN THE
This Invention is designed principally for joining hose pipes such as are used
in connection with fire-engines, but it is also equally applicable for joining or
connecting flexible or other pipes used for the transmission of liquids or gaseous
fluids.
The Invention consists principally in dispensing entirely with the screw thread
or other similar inclined surfaces usually employed for connecting the two parts
of the joint together by turning or partially turning round one part thereof, and
in so arranging the parts that the junction is completed by merely thrusting one
part into the other without any screwing or turning action whatever.
Such being the nature and object of my said Invention, I will now proceed to
describe the manner in which the same is to be or may be performed or carried into
practical effect; and in order that the same may be distinctly understood I have
annexed hereunto a Sheet of Drawings illustrative thereof, and have marked the
same with figures and letters of reference corresponding with those in the following
explanation thereof.
Fig. 1 in the annexed Drawing shows the two parts of the joint separated, the
spiget" part a, a, being in elevation, and the "faucet" part b, b, being in section;
Fig. 2 is a similar view showing the joint made fast.
The joint consists mainly of these two short cylindrical parts, each of which is
attached by tying, binding, or otherwise, in the usual manner to the end of its
respective length of hose.
The "spigot" part a, a, is made of smaller diameter than the "faucet " part b, b,
so that it can pass inside the mouth of the latter, as usual; but surfaces at this
part are merely cylindrical and not tapped with a screw thread or provided with
inclined projections as heretofore.
The opener or "spigot" part a, a, has near its end a circular or annular groove or
recess c, c, formed in its outer circumference, and the outer or faucet part b, b, is
provided with two corresponding spring bolts d, d, projecting inwards and having
their ends bevilled like a latch.
When the spigot part a, a, of the joint is pressed forward into the faucet part b, b,
the bevilled or rounded end of the former at e, e, presses against the bolts d, d,
forcing them outwards until the annular groove c, c, comnes opposite to the bolts d, d,
when the springs f. f, will force the latter forward with the annular groove c, c,
and the two parts a, a, and b, b, will become locked, as shown at Fig. 2.
The spring bolts d, d, work through two lugs or projections g, g, on the part b, b,
of the joint, and their external ends are provided with knobs h, h, (as shown by
dotted lines in Fig. 1) when it is desired to separate the two parts so as to discon-
nect the hose pipe.
In order to make a water-tight joint or air or gas-tight joint a ring i, i, of india-

page_text: #
rubber is let into an annular recess formed in the part b, b, and the end e, e, of the
part a, a, beds against this ring as it is forced into the part b, b. This ring is
provided with an annular lip which, when there is any pressure of water or other
Huid inside the pipe, becomes forced outwards and assists in making a good joint.
I would, however, here observe that I make no claim to the construction or use of
this india-rubber ring, as I am aware that india-rubber rings of a similar form
have been in ordinary and common use for similar purposes.
It will be evident that this construction of joint is equally applicable for joining
flexible hose on to fixed stand pipes, pumps, or taps, and for other similar purposes.
Having now described the nature and object of my said Invention for "Improve-
ments in the Construction of Union Joints for Hose Pipes," together with tho
manner in which the same is to be or may be carried into practical effect, I would
remark in conclusion that I clain as my Invention, the combination of an annular
recess round the outside circumference of the inner or spigot" part of the joint,
with one or more (preferably two) spring bolts locking thereinto and attached to
the outer or faucet" part of the joint, the whole being constructed and arranged
substantially in the manner and for the purposes herein-before more particularly
set forth.

In witness whereof, I, the said John Morris, have hereunto set my hand and
seal, this Thirteenth day of September, in the year of our Lord One thousand
eight hundred and seventy-seven.
