Year: 1874

page_text: LETTERS PATENT to Frederick Barker Hill, of No. 19, Lambeth Road,
Southwark, in the County of Surrey, Engincer, for the Invention of
"IMPROVEMENTS IN CONNECTING APPARATUS FOR COUPLING HOSE AND OTHer
PROVISIONAL SPECIFICATION left by the said Frederick Barker
Hill at the Office of the Commissioners of Patents, with his
Petition, on the 26th August 1874.
I, FREDERICK BARKER HILL, of No. 19, Lambeth Road, Southwark,
in the County of Surrey, Engineer, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN CONNECTING APPARATUS FOR COUPLING
HOSE AND
OTHER PIPES, AND SECURING COVERS ON
PIPES AND IN OTHER
SITUATIONS," to be as follows:-
This Invention relates to apparatus for coupling or connecting
together lengths of hose or other pipe, which apparatus is applicable

page_text: also for securing covers over the ends of hose or other pipes, the suction
and delivery orifices of pumps, and in other situations.
For connecting lengths of pipe together one end of each pipe is
formed externally with a male screw thread, on to which is fitted a ring
formed with a corresponding female screw. This screwed ring is pro-
vided with overhanging parts or lugs arranged to overlap a suitably
faced flange on the end of the length of pipe to be connected to its own.
These overhanging lugs are so arranged that the said flange may be
slipped in sideways, so that on turning the screwed ring its lugs shall
draw and hold the faced end of the flanged pipe tightly against the end
of the pipe which carries the ring. The ring is provided with projections
for screwing it up, and a slot and pin or equivalent means are provided
for limiting its extent of movement so that it shall always be kept over
and protect from injury the male screw on its pipe.
For covers, the periphery of the cover takes the place of the pipe
flange above mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick Barker Hill in the Great Seal Patent
Office on the 26th February 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
BARKER HILL, of No. 19, Lambeth Road, Southwark, in the County of
Surrey, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-sixth day of August, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Frederick Barker Hill, Her
special license that I, the said Frederick Barker Hill, my executors,
administrators, and assigns, or such others as I, the said Frederick
Barker Hill, 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

page_text: Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN CONNECTING APPARATUS FOR COUPLING HOSE AND
OTHER PIPES, AND SECURING COVERS ON PIPES AND IN OTHER SITUATIONS," upon
the condition (amongst others) that I, the said Frederick Barker Hill,
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 Frederick Barker Hill, 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 thereof and the Drawings therein referred
to (that is to say):-
This Invention relates to apparatus for coupling or connecting
together lengths of hose or other pipes, which apparatus is applicable
also for securing covers over the ends of hose or other pipes, the suction
and delivery orifices of pumps, and in other situations.
For connecting lengths of pipe together, one end of each pipe is
formed externally with a male screw thread, on to which is fitted a ring
formed with a corresponding female screw. This screwed ring is pro-
vided with overhanging parts or lugs arranged to overlap a suitably
faced flange on the end of the length of pipe to be connected to its own.
These overhanging lugs are so arranged that the said flange may be
slipped in sideways, so that on turning the screwed ring its lugs shall
draw and hold the faced end of the flanged pipe tightly against the end
of the pipe which carries the ring. The ring is provided with pro-
jections for screwing it up, and a slot and pin or equivalent means arc
provided for limiting its extent of movement so that it shall always be
kept over and protect from injury the male screw on its pipe.
For covers, the periphery of the cover takes the place of the pipe
flange above mentioned.
Such being the nature of my Invention, I now proceed to describo
the manner of carrying the same into practical effect.
In the accompanying Drawings the same letters of reference are
applied to like parts in all the views.

page_text: Fig. 1 is a central longitudinal section of my improved hose coupling.
Fig. 2 is a detached sectional view of the screwed ring; and Fig. 3 is
a front view of the same. a is one end of a length of pipe formed
externally with a male screw thread b, on to which is fitted a ring c
formed with a corresponding female screw, as shewn. The ring c is
formed with overhanging parts or lugs d arranged to overlap a suitable
flange e (faced with a leather or similar washer e¹) on the end of the
length of pipe f to be connected to the pipe a. As will be seen the lugs d
are so arranged that the flange e may be slipped in sidewise, as indicated
by the arrow in Fig. 3, when on turning the ring c by its projections
the lugs & will draw the facing et tightly against the end of the pipe a,
where it will be securely held by the ring c. The facing e¹ is made
slightly less in thickness than the depth of the annular recess, thus a
guide is formed to facilitate placing the two pipes rapidly in their
proper relative positions for being coupled up. h is a pin screwed into
the ring c and operating in conjunction with a projection i on the pipe a
to prevent the ring being turned too far in either direction, and so as to
ensure its being kept over the thread. The pitch of the thread is such
that even assuming the leather facing e¹ to drop out one turn of the ring
will suffice to bring the flange e into contact with the end of the pipe a.
Figs. 4, 5, and 6 shew a modified form of coupling in which more
than one turn of the ring c is required to disconnect the pipes from each
other. In this case the annular recess in the end of the pipe ƒ is made
of greater depth than in the preceding arrangement, and in order to
allow the ring c to be turned more than once without leaving the pipe a
the pin is made to hold in place between projections c¹ on the ring ca
small plate which works between shoulders a¹, a², on the pipe a so as
to limit the extent of movement of the ring c according to the distance
between the shoulders a', a².
Fig. 7 illustrates my Invention as applied to secure a cover (7) on the
end of a pipe, and will be readily understood without further
description.
Figs. 8, 9, 10, and 11, shew the application of my Invention for
securing a cover on to a bottle or jar m. The bottle or jar m is formed
with two projections m³, m³, and the ring c has cast or formed upon it
a projection which is originally in the position indicated by dotted
lines in Figs. 8 and 9; but after the ring has been screwed on to the

page_text: bottle this projection is bent into the position shewn in full lines so as
to operate in conjunction with the stops m³, m³, to limit the movement
of the ring c.
Figs. 12, 13, and 14 shew a modification applicable to bottles and
jars, which will readily be understood from the Drawings without
further description.
Having described my said Invention, and having explained the
manner of carrying the same into practical effect, I hereby declare what
I consider to be novel and original, and therefore claim as the Invention
secured to me by the herein-before in part recited Letters Patent to
bc,-
First. The constructing the coupling so as to enable a pipe, flange, or
cover to be slipped sidewise into position between the overlapping parts
of the holding lugs and the end of the pipe carrying the ring, as above
described.
Secondly. The constructing and arranging coupling apparatus, as
shewn in and described with reference respectively to Figs. 1, 2, and 3,
Figs. 4, 5, and 6, Fig. 7, and Figs. 8, 9, 10, and 11 of the Drawings, for
the purposes specified.
In witness whereof, I, the said Frederick Barker Hill, have here-
unto set my hand and seal, this Twenty-fifth day of February, in
the year of our Lord One thousand eight hundred and seventy-
five.
FREDERICK BARKER HILL. (L.S.)
