page_text: LETTERS PATENT to Sir Antonio Brady, Knight, Henry Eeles Dresser,
and Marshall Mason Harris, all of 114, Cannon Street, in the
City of London, for the Invention of "IMPROVEMENTS IN COUPLINGS.".
A communication from abroad by William Washburn, of the City
of Brooklyn, United States of America.
Sealed the 12th April 1872, and dated the 19th October 1871..
PROVISIONAL SPECIFICATION left by the said Sir Antonio Brady,
Henry Ecles Dresser, and Marshall Mason Harris at the Office,
1
of the Commissioners of Patents, with their Petition, on the 19th
October 1871.
5. We, Sir ANTONIO BRADY, Knight, HENRY EELES DRESSEE, and
MARSHALL MASON HARRIS, all of 114, Cannon Street, in the Oity
of London, do hereby declare the nature of the said Invention for

page_text: “IMPROVEMENTS IN COUPLINGS," a communication to us from abroad by
William Washburn, of the City of Brooklyn, United States of America,
to be as follows:-
This Invention consists in forming a coupling collar or the ends of
hose, of pipes, of rods (or other things requiring to be coupled) with
lugs or projections (inclined by preference) of such form that one lug on
the one collar, or section, or thing to be coupled shall fit or interlock
with the other lug or the other collar or thing to be coupled, as, for
example, thus,
a being one lug, and 6 a corresponding lug,
the parts c, d, and e, f, of which are to be brought together when
coupling is to be effected. The coupling ends or coupling collars are to
be fitted with slotted keys, pins, and key seats, or they may be fitted
with screws and binding nuts (slantingly notched by preference) working
thereon and acting against the exterior, which nuts being screwed to the
right or the left bind or release the two parts of the coupling. Packing 1
is applied to this coupling by means of channels in the abutting ends,
and an opening may (when the coupling is used for pipes for steam or
other similar fluid) be made to allow the steam or fluid to press the
packing tight home although screwing up wil. usually ensure tight
coupling.
Amongst other applications of this Invention may be mentioned the
coupling of pipes for air, gas, water, and other fluids, coupling of engines,
tenders, and railway carriages, though the use of this coupling is not
restricted to the purposes above named, but is applicable to coupling
purposes generally.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Sir Antonio Brady, Henry Eeles Dresser, and
Marshall Mason Harris in the Great Seal Patent Office on the 19th
April 1872.

greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of October, in the year
5 of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Sir Antonio Brady, Henry Eeles Dresser,
and Marshall Mason Harris, Her special licence that we, the said
Sir Antonio Brady, Henry Eeles Dresser, and Marshall Mason Harris,
our executors, administrators, and assigns, or such others as we, the said
Sir Antonio Brady, Henry Eeles Dresser, and Marshall Mason Harris,
our 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 COUPLINGS," a communication to us from abroad by
William Washburn, of the City of Brooklyn, United States of America,
upon the condition (amongst others) that we, the said Sir Antonio Brady,
) Henry Eeles Dresser,' and Marshall Mason Harris, our executor's or
administrators, by an instrument in writing under our, 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 wc, the said. Sir Antonio Brady, Henry Ecles
Dresser, and Marshall Mason Harris, do hereby declare the nature of
our said Invention, and in what manner the same is to be performed,
O to be particularly described and ascertained in and by the following
statement :-
.
This Invention consists in forming a coupling collar or the ends
of hose, of pipes, of rods (or other things requiring to be coupled) with.
lugs or projections (inclined by preference) of such form that one lug

page_text: coupling ends or coupling collars are to be fitted with slotted keys,
pins, and key seats; or they may be fitted with screws and binding
nuts (slantingly notched by preference) working thereon and acting
against the exterior, which nuts being screwed to the right or the left
bind or release the two parts of the coupling. Packing is applied to
this coupling by means of channels in the abutting ends, and an
opening may (when the coupling is used for pipes for steam or other
similar fluid) be made to allow the steam or fluid to press the packing
tight home although screwing up will usually ensure tight coupling.
Amongst other applications of this Invention may be mentioned the
coupling of pipes for air, gas, water, and other fluids, coupling of engines,
tenders, and railway carriages, though the use of this coupling is not
restricted to the purposes above named, but is applicable to coupling
purposes generally.
-
The Drawings accompanying this Specification at Figs. 1 and 2 illus
trate the form of the arrangements adopted when slotted keys or pins
and key scats are used. In this case the two corresponding sections
of the coupling are fitted, interlocked, and keyed' together with elastic
packing in the joint. The fixed cars or inclined lugs marked E are
formed upon the parts of a hose coupling for interlocking or holding such
parts in contact and a hose coupling is formed of the part A and duplicate
part A', each having two cars or inclined lugs thereon as described in
combination with the slotted keys K, pins e, and key seats, the whole
constructed and operating substantially as set forth. The packing is
applied to a hose coupling by means of the channels f, n, f, and packing P
inserted therein.
Figs. 3 (elevation) and 4 (plan) in the said Drawings illustrate the
form of the arrangements adopted when exterior nuts are used. The
same letters (as far as used) refer to similar parts described in Figs. 1
and 2 with the addition of G, which indicates the exterior nuts.
Having now particularly described and ascertained the nature and
object of our Invention, and in what manner the same may be performed
or carried out in practice, we hereby declare that we claim the Invention
herein-before described and illustrated by the accompanying Drawings,
it being understood that we do not claim (nor do we limit ourselves to
the use of) the mere mechanical constituent details herein-before

page_text: described and represented by the Drawings except as constituents of the
said Invention as herein-before described.
In witness whereof, we, the said Sir Antonio Brady, Henry Ecles
Dresser, and Marshall Mason Harris, have hereunto set our hands
and seals, this 17th day of April, in the year of our Lord One
thousand eight hundred and seventy-two.
