PROVISIONAL SPECIFICATION left by the said John Henry Johnson at the
Office of the Commissioners of Patents, with his Petition, on the 1st
January 1862.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn- Fields, in the County of
Middlesex, and of 166, Buchanan Street, in the City of Glasgow, North
Britain, Gentleman, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN HOSE PIPE JOINTS OR COUPLINGS," a communication from
Thomas Braisted, of New York, in the United States of America, to be
as follows:-
This Invention relates to certain peculiar constructions and arrangements of
joints or couplings for hose pipes, whereby a perfectly tight coupling may be
effected in a ready and expeditious manner.
According to one modification it is proposed to use two metal cylinders or
collars fitted respectively in any convenient manner to the ends of the hose
pipes to be coupled. One of these cylinders or collars is made to fit easily
inside the other, and has a bevelled groove made round it a short distance from
its inner extremity or end face, which face bears against a packing ring or

page_text: washer of any suitable material inserted inside the larger or outer cylinder.
An inner projection or flange which is bevelled to correspond to the bevel of
the groove in the inner cylinder is formed on the inner surface of the outer
cylinder, and fits into the groove above mentioned. On the diametrically
opposite side of the outer cylinder to that in which the internal projection is
situate, there is a wedge or screw plug passing through the cylinder and
through a collar thereon, and provided at its outer end with a suitable head
for turning the screw, whilst the inner end of the pin or plug is tapered or
bevelled to fit the groove in the inner cylinder before referred to. In coupling
the parts the screw pin or plug is partially withdrawn so as to allow the
inner cylinder to enter the outer one freely and pass its end over the internal
bevelled projection so as to cause such projection to fit into the bevelled groove,
the screw plug is now caused to enter the groove on the opposite side by turning
it either by hand or a spanner, the effect being to lock the two parts effectively
together.
According to another arrangement the two cylinders or collars are of the
same size, and a tight joint is formed by causing their two faces to abut firmly
together, a suitable packing ring being inserted between the abutting surfaces.
One of the cylinders is provided with a flange, which is hooked at one
side, and provided with an inclined staple at the diametrically opposite
side; the hook engages with a projection or flange on the second cylinder and
the staple passes through an opening or notch cut away for that purpose in
the corresponding part of the opposite cylinder. The inner surface of the
hook, and the outer surface of the flange where the hook engages, are both
inclined or bevelled in such a manner as to insure the perfect tightening of
the parts. A wedge or key is passed through a keyway in the staple, and
bears against the face of the flange of the second cylinder, which face is so
inclined as to present a perfectly flat surface to the action of the wedge or key.
A strap or chain may connect the key with the parts so as to prevent its being
lost. A small projection is formed inside the hook above mentioned, and a
corresponding notch or opening is formed in the flange over which the hook
engages, so as to ensure the accurate fitting of the parts or cylinders in their
proper position with regard to each other. In uniting the joint, the flange of
the second cylinder is passed into the hook on the flange of the first cylinder and
the key or wedge is then inserted into the staple and driven home, when
by its pressure on the inclined face of the flange of the second cylinder it forces
the two firmly together by imparting a simultaneous, vertical, and lateral
movement thereto.

by the said John Henry Johnson, in the Great Seal Patent Office on the
1st July 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN HENRY
JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex, and of 166,
Buchanan Street, in the City of Glasgow, North Britain, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of January, in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Henry Johnson, Her special license that I, the said John Henry Johnson,
iny executors, administrators, and assigns, or such others as I, the said John
Henry Johnson, my executors, administrators, or 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
PIPE JOINTS OR COUPLINGS," a communication from abroad by Thomas Braisted,
of New York, in the United States of America, upon the condition (amongst
others) that I, the said John Henry Johnson, my executors or administrators,
by an instrument in writing under my hand and seal, or under the hand and
seal of one of them, 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 John Henry Johnson, 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 bad to the accompanying Drawings, and to the
letters and figures marked thereon, that is to say:
The said Invention relates to certain peculiar constructions and arrangements
of joints or couplings for hose pipes whereby a perfectly tight coupling may be
effected in a ready and expeditious manner.
According to one modification it is proposed to use two metal cylinders or
collars fitted respectively in any convenient manner to the ends of the hose
pipes to be coupled. One of these cylinders or collars is made to fit easily
inside the other, and has a bevelled groove made round it a short distance from

page_text: its inner extremity or end face, which face bears against a packing ring or
washer of any suitable material inserted inside the larger or outer cylinder.
An inner projection or flange which is bevelled to correspond to the level of
the groove in the inner cylinder, is formed on the inner surface of the outer
cylinder and fits into the groove above mentioned. On the diametrically
opposite side of the outer cylinder to that in which the internal projection is
situate, there is a wedge or screw plug passing through the cylinder and
through a collar thereon, and provided at its outer end with a suitable head
for turning the screw, whilst the inner end of the pin or plug is tapered or
bevelled to fit the groove in the inner cylinder before referred to. In coupling
the parts, the screw pin or plug is partially withdrawn so as to allow the inner
cylinder to enter the outer one freely, and pass its end over the internal
bevelled projection so as to cause such projection to fit into the bevelled groove.
The screw plug is now caused to enter the groove on the opposite side by
turning it either by hand or a spanner the effect being to lock the two parts
effectually together.
According to another arrangement the two cylinders or collars are of the
same size, and a tight joint is formed by causing their two faces to abut firmly
together, a suitable packing ring being inserted between the abutting surfaces.
One of the cylinders is provided with a flange, which is hooked at one side,
and provided with an inclined staple at the diametrically opposite side; the
hook engages with a projection or flange on the second cylinder and the staple
passes through an opening or notch cut away for that purpose in the corre-
sponding part of the opposite cylinder. The inner surface of the hook, and the
outer surface of the flange where the hook engages, are both inclined or
bevelled in such a manner as to insure the perfect tightening of the parts. A
wedge or key is passed through a keyway in the staple and bears against the face
of the flange of the second cylinder, which face is so inclined as to present a
perfectly flat surface to the action of the wedge or key. A strap or chain may
connect the key with the parts so as to prevent its being lost. A small pro
jection is formed inside the hook above mentioned, and a corresponding notch
or opening is formed in the flange over which the hook engages so as to insure
the accurate fitting of the parts or cylinders in their proper position with
regard to each other. In uniting the joint the flange of the second cylinder
is passed into the book on the flange of the first cylinder, and the key or wedge
is then inserted into the staple and driven home, when by its pressure on the
inclined face of the flange of the second cylinder it forces the two firmly
together by imparting a simultaneous vertical and lateral movement thereto.

page_text: And in order that the said Invention may be fully understood, I shall now
proceed more particularly to describe the same, and for that purpose I shall
refer to the several Figures on the Sheet of Drawings hereunto annexed, the
same letters of reference indicating corresponding parts throughout all the
corresponding Figures.
Figure 1 of the Drawings is a view of the inner or smaller cylinder or
thimble; Figure 2 is a view of the outer or larger cylinder or thimble; and
Figure 3 represents a longitudinal section of the two connected.
pro-
A is a hollow cylinder or thimble with an internal flange or bevelled
jection a on one side, situate near the shoulder or packing seat b, a sufficient
space being left between it and the shoulder or packing seat to receive a
packing ring or washer of leather or other suitable material, and also the
enlarged or bevelled end 6 of the cylinder or thimble B, as shewn in Figure 3,
the flange or bevelled projection a being so constructed that it may freely pass
into the bevelled groove d. Opposite to the flange a in the cylinder or thimble A
is an opening or hole passing through the cylinder or thimble and through the
collar or boss e, e, shewn on the outer side of the cylinder or thimble A, on
which it is cast or fastened, and is used either as a screw or nut for forcing the
wedge or bevelled end pin f into and against the bevelled edge of the bevelled
groove in the cylinder or thimble B. g is the cap or nut of the screw attached
to or forming part of the wedge or bevelled end pin f, and situated over the
collar e, e.
It will be seen that the collar e, e, by having the threads of a
screw cut around its outer surface becomes the screw, and the cap g the nut,
or if the thread be cut inside of the collar, the cap g becomes the head of the
screw, and the collar the nut. B is the inner or smaller cylinder or thimble,
having a shoulder h, h, to receive the outer end of the cylinder or thimble A.
It is made to pass into the cylinder or thimble A with sufficient ease to
allow the enlarged end or projecting flange & beyond the bevelled groove d,
to pass easily over the flange or bevelled projection a, the wedge or bevelled
end pin f being drawn up so as to leave the side opposite the flange or bevelled
projection a clear. The bevelled groove d extends around the outer circum-
ference of the cylinder or thimble B as before stated, and when passed into
the cylinder or thimble A, the end and projection beyond the bevelled
grooved.after passing the flange or bevelled projection a drops behind it, and
the wedge or bevelled end pin f is then forced down into the groove and
against the bevelled edge by turning the cap 9, which is formed so as to be
used by the hand or by a wrench.
The ends i, i, of the cylinders or thimbles opposite to those forming the
connection are of the same circumference, and are provided for attaching the

page_text: hose or pipe to them, which may be done by means of bands and screws or
rivets, or in any other suitable manner.
Figure 4 is a side view of another form of coupling.
Figure 5 is a longitudinal section of the same, and Figures 6, 7, 8 and 9 are
end views thereof.
In these Figures A is a hollow cylinder, with an external flange a, one
side of one end of such cylinder being made in the form of a hook a, a, and
bearing upon the opposite side a' a projection or staple c with a hole d' made
through it for receiving the key d; the said hollow cylinder A being connected
with a hollow cylinder B by means of the flange b on the hollow cylinder B
and the flange a and staple c on the hollow cylinder A, and held firmly in its
place by the key d being driven through the hole d' in the staple c, and press-
ing the flange b firmly upon the packing Z (made of leather or any other
suitable material) inserted in a groove made in the flange a, thereby making
the joint water-tight between the flanges a and b of the two cylinders, or parts
A, B, of the coupling.
The flange a on the side a, a, has a semicircular (or any other shaped)
projection h made inside of the hook, and the inside face g of the hook is made
bevelling or inclining from the inside of the lip of the hook towards the face
of the flange a.
The staple c is made inclining outwards so as to allow the
flange of the part B to pass inside, which flange b, on the side b¹, has a
recess or notch c, c, of sufficient size to pass over the staple c, the said recess
or notch c, c, being bevelled or inclined inwards from near the face k of the
flange 6, to facilitate the passage of the flange 6 over the staple c. The flange
b on the side b¹ has one face k bevelled or inclined outwards at such an angle
that when the flange 6 is in its place the angle of inclination of the face k may
be at right angles to the inclination of the staple c. In the opposite side b, b,
of the flange b, there is a semicircular (or any other formed) recess or notch
h' corresponding to the projection h of the hook on the side a, a, of the flange
a, and the bevelled or inclined face of this part of the flange corresponds to the
face g of the hook, by which means, when the flange 6 is forced towards the
flange a, in the act of coupling hose, the face g, by its inclination causes the
flange 6 to press firmly on the packing Z, and the flange b is kept from lateral
motion by the projection h, and the recess or notch h¹, and the key d being
driven through the hole d' in the staple c, and bearing upon the inclined sur-
face k, prevents the two parts A and B from becoming detached from one
another when coupled together. The key d is prevented from being lost by
the leather strap e attached at one end to the loop f on the key d, and at the
other end to the loop f' on the part A of the coupling.

page_text: C, is the hose screwed inside of the parts A and B of the coupling and kept
in place by the inner cylinder D placed inside of the hose C, and rivetted
through the hose C to the parts A and B of the couplings.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that 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 is,-
First, the general constructions and arrangements of joints or couplings for
hose pipes, as herein-before described and illustrated by the Drawings.
Second, the combination of the parts A and B with the bevelled projection
a, and wedge or bevelled end pin f, substantially as herein-before described and
illustrated by Figures 1, 2, and 3 of the Drawings.
Third, the combination with each other and with the parts A, B, of the
bevel lipped hook a, a, and the bevel faced flange b, b, in the manner and for
the purpose herein-before described in reference to Figures 4, 5, 6, 7, 8, and 9,
of the Drawings.
Fourth, constructing the hook a, a, and flange b, b, respectively with a
projection and recess h, h¹, in the manner and for the purpose herein-before
described.
Fifth, the combination with the parts A, B, of the incline faced flange b',
staple c, and wedge d in the manner herein-before described and illustrated in
reference to Figures 4, 5, 6, 7, 8, and 9 of the Drawings.
In witness whereof, I, the said John Henry Johnson, have hereunto set
my hand and seal, the First day of July, in the year of our Lord One
thousand eight hundred and sixty-two.
I HENRY JOHNSON
