page_text: Improved Means for Coupling together the Ends of Pipes and
other Cylindrical Ends.
I, HENRY BOTTEN of N° 39 Lime Street in the City of London Signal Engineer
do hereby declare the nature of this invention to be as follows:-
To couple together end to end the metallic tubular end pieces of flexible hose
and other pipes I make each end piece with an enlarged head-on the exterior of
the head of one I cut two inclined grooves like screw threads each passing around
nearly one half of its circumference-the end of each groove nearest to the outer
end of the head I continue in a direction lengthwise of the head towards the outer
end so as to make an open mouth to this end of the groove. Around the exterior
of the head of the other I place a loose tubular collar with a flange at its rear end
to bear against the rear end of the head and with two inwardly projecting lugs on
two opposite sides of its interior.
When the heads of the two end pieces are brought together the lugs in the collar
which surround one head are made to enter the mouths of the grooves cut in the
other head-A partial turn is then given to the collar so causing the lugs to move
along the screw thread portions of the grooves and thereby locking the two end
pieces tightly together.
The heads may either be made to butt one against the other with a washer
between them or a projecting ring on the face of one may enter a recess in the face
of the other in which an elastic ring may be held, or one end may be formed with
a conical projection to fit into a corresponding recess in the other."

The same means may be employed for connecting other cylindrical ends-For
example the ends of the shafts or poles of carriages might be made cylindrical and
be coupled by couplings formed in the above manner to short cylindrical pieces on
the carriage or for coupling the ends of the driving shafts for machinery.

other Cylindrical Ends.
I, HENRY BOTTEN of N° 39.Lime Street in the City of London Signal Engineer
do hereby declare the nature of this invention and in what manner the same is
to be performed to be particularly described and ascertained in and by the
following statement :—
To couple together end to end the metallic tubular end pieces of flexible hose
and other pipes I make each end piece with an enlarged head, on the exterior of
the head of one I cut two inclined grooves like screw threads each passing around
nearly one half of its circumference the end of each groove nearest to the outer

of the head of the other I place a loose tubular collar with a flange at its rear end
to bear against the rear end of the head and with two inwardly projecting lugs on
two opposite sides of its interior.
When the heads of the two end pieces are brought together the lugs in the collar
which surround one head are made to enter the mouths of the grooves cut in the
other head. A partial turn is then given to the collar so causing the lugs to move
along the screw thread portions of the grooves and thereby locking the two end
pieces tightly together.
The heads may either be made to butt one against the other with a washer

face of the other in which an elastic ring may be held, or one end may be formed
with a conical projection to fit into a corresponding recess in the other.
The same means may be employed for connecting other cylindrical ends. For
example the ends of the shafts or poles of carriages might be made cylindrical and
be coupled by couplings formed in the above manner to short cylindrical pieces on
the carriage or for coupling the ends of the driving shafts for machinery.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figures 1 and 2 are perspective views showing the ends of two metal pipes with
my improved coupling.
Figure 3 is a side elevation of these pipes connected together by the coupling.
Figure 4 is a perspective view of a stop cock carrying one part of my improved
coupling and thereby adapted to receive a hose pipe or other pipe, which can at
pleasure be connected with it and removed.
Figure 5 is a perspective view of one part of my coupling so formed that it can be
fixed upon a table or other surface and serve for the attachment when required of
a standard or bracket, it may be to carry a lamp or for any other purpose where it
is desirable that the standard or bracket should be capable of being readily fixed

page_text: and removed. This form shown by Figure 5 may also be used as a fixture upon a
tank or other vessel to receive from time to time a hose or other pipe to be used
either to fill or to empty the vessel. There are many other purposes some of which
I have previously named to which my coupling for pipes and other cylindrical ends
may be employed.
The part couplings shown in the Figures 4 and 5 are to be used with other parts
similar to that shown by Figure 2 and these latter will in the case of Figure 4 be
formed either in connection with a metal pipe or an end or ferrule suitable to form
the attachment for a hose pipe; and in the case of Figure 5 the part coupling will
be formed in connection with a standard or bracket or a cap or cover or a pipe or
a short cylindrical or tubular ferrule suitable for the attachment of a hose pipe. In
these figures a is an enlarged head formed on the part of the coupling shown by
Figure 1 and b. b are two inclined grooves cut upon the exterior of the head a.
b¹¹ are the longitudinal continuations or entrances to the grooves bb c is an
enlarged head and collar on the part represented by Figure 2. The head and collar
are in this figure shown as formed together and all in one piece; when this
construction is adopted the entire pipe or part is turned in the operation of
coupling and uncoupling..
In many cases this is convenient but in others it is desirable that the collar alone
should turn. The loose collar in that case is provided with an inwardly projecting
flange which bears on a corresponding flange on the head or end of the pipe or part.
The collar is provided with two luga adapted to enter the mouths 6' 6' of
the inclined grooves b.
The lugs shown in the drawing are comparatively narrow and this form is
convenient when the coupling is not required to be of great strength but when
strength is necessary I increase the width of the lugs co¹ so that each extends
over an arc of 90 degrees or nearly so and of course I make the mouths b¹ b¹ wide
enough to admit the lugs. The grooves d, seen in Figures 2 and 3 are intended to
receive a packing ring but the joint may be rendered tight by other means as
already stated:-
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. A pipe coupling having a cylindrical head a with grooves b. 61 on one part
and a collar c with lugs on the other part substantially as described.
2. Apparatus for coupling pipes and other cylindrical ends substantially as
described and illustrated by the annexed drawings.
