66, Chancery Lane, in the County of Middlesex, Mechanical
Draughtsman, for the Invention of "IMPROVEMENTS IN HOSE COUPLINGS
AND IN THE MEANS FOR ATTACHING THE SAME TO HOSE."-A communication
from abroad by Daniel Ashworth, of Wappengers Falls, in the
State of New York. United States of America.
Sealed the 17th July 1874, and dated the 12th March 1874.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 12th March 1874.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery.
Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby,
declare the nature of the said Invention for "IMPROVEMENTS IN HOSE
COUPLINGS, AND IN THE MEANS FOR ATTACHING THE SAME TO HOSE," to be as
follows:-
:

page_text: of the hose to be coupled, such rings being formed with hook-shaped
lugs engaging with notched inclined surfaces on the ring opposite in
order to couple and tighten the two sections of hose. This part of the
Invention consists,―
Secondly. In an abutment on the face of the inclined surface for the
purpose of preventing the improper disengagement of the lug.
Thirdly. In a rack or series of teeth or notches on the faces of the
rings for the purpose of tightening the joint by means of a pinion or its
equivalent, which gears into the teeth or notches, and when turned will
give an axial motion in opposite directions to the rings of the coupled
sections.
And, Fourthly. In a packing of peculiar form applied to the face of
each of the rings. for the purpose of preventing leakage when the
sections are coupled. The packing consists of an india-rubber gasket,
which is held in place in a rebated ring groove.
The Invention further consists in a band or. strap häving at its ends
hooked lugs (with a shoulder) adapted to embrace the hose and the
neck of each section of the coupling. These lugs when interlocked by
applying pressure to their shoulders are secured by a key, which con-
tracts the said band around the hose and draws it tightly into a groove
or cavity in the neck thereof.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
.
filed by the said Alfred Vincent Newton in the Great Seal Patent
Office on the 11th September 1874..
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED 2
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Mechanical Draughtsman, send greeting:
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of March, in the year
of our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alfred Vincent Newton, Her special
licence. that I, the said Alfred Vincent Newton, my executors, adminis-

page_text: trators, and assigns, or such others as I, the said Alfred Vincent Newton,
my executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN HOSE COUPLINGS, AND IN THE MEANS FOR ATTACHING THE SAME TO HOSE,"
being a communication to me from abroad by Daniel Ashworth, of
Wappingers Falls, in the State of New York, United States of America,
upon the condition (amongst others) that I, the said Alfred Vincent
Newton, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what
manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alfred Vincent Newton, do hereby
declare the nature of the said Invention; and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing here,
unto annexed, and to the letters and figures marked thereon (that is to
say)
One part of this Invention relates to certain improvements in hose
couplings, in which the coupling devices consist of a pair of annular
discs, cach of which is formed with hook-shaped lugs engaging with
notches and inclined surfaces on the opposite one in order to couple and
tighten two sections of hose..
This part of the Invention consists,—
Firstly. In the combination of a pair of annular discs, cach having

page_text: tightening of the sections by means of a suitable tool (see Fig. 4)
consisting of a lever or bar with one end bent, and a pinion H formed
thereon. By inserting the pinion between the racks and moving the
lever in the proper direction the hooked lugs C are caused to travel up
the inclines E and tighten the parts.
The improved packing consists of a rubber gasket I, which is held in
place by means of an annular groove in the face of the disc, the bottom
of the groove being wider than the other portion, and the rear portion
of the gasket being of corresponding form and pressed into place
therein. The front or face portion of the gasket is formed with a
flange i projecting inward, so that when in place there is a slight space
between said flange and the face of the disc. When the sections are
coupled together the gaskets face each other, as shown in Fig. 2, so
that the pressure of the water in the hose or pipe has a tendency to press
the flanges into close contact with cach other so as to form a tight joint
and prevent leakage.
If desired the surfaces E may be parallel with the faces of the discs
instead of inclined, and the parts made to fit so closely that the pressure
of the water upon the flanges will be sufficient to prevent leakage. The
_necks A may have lugs or projections a' in rear of the discs to facilitate
the turning of the same in coupling or uncoupling.
The fastening for attaching the hose to the coupling consists of a band
or strap L (Figures 5, 6, and 7), of suitable flexible metal formed with
hooked lugs at its ends and with shoulders or projections slightly
in rear thereof.
The neck A is inserted in the end of the hose M, the band or strap L
passed around the outside, so that the hooked lugs will interlock, and
a tapering key or wedge K is driven between them, as shown, so as to
hold the band securely in position with the hose pressed into the
groove.
By means of the shoulders or projections & the band may be held in
a vice or other suitable tool while the key is being fitted, and by the
same means it may be held when it is desired to remove the key.
The band or strap L holds the hose closely in place, and the collar a
effectually prevents it from slipping off the neck,

page_text: Having now set forth the nature of the Invention of "Improvements
in Hose Couplings, and in the Means for Attaching the same to Hose,"
as communicated to me by my foreign correspondent, and explained the
manner of carrying the same into effect, I wish it to be understood that
under the above in part recited Letters Patent I claim,-
First. The combination of the discs B, each having one or more hook-
_shaped lugs C, notches D, and inclined surfaces E, substantially as and
for the purpose shown and described.
Second. The abutments e on the inclined surfaces E, substantially as
"shown and described for the purpose specified..
Third. The racks G opposite to each other on the discs B, in com-
bination with the pinion H, substantially as shown and described.
Fourth. The two internally flanged gaskets I, in combination with
each other, and with the discs B of the coupling, substantially as shewn
and described.
Fifth. The band or strap L formed with the hooked lugs and fitted
with the wedge or key K, in combination with the hose and the neck of
the coupling, substantially as and for the purpose shown and described.
Sixth. The shoulders or projections on the band L, as shewn and
described for the purpose specified.
In witness whereof, I, the said Alfred Vincent Newton, have
hereunto set my hand and scal, the Tenth day of September,
in the year of our Lord One thousand eight hundred and seventy-
