PROVISIONAL SPECIFICATION.
Improvements in Joints or Connections for Rods, Tubes, and
Wire Ropes.
We, JOSEPH WILLIAM BRISTOL, and WILLIAM WALTER BRISTOL, trading
together as J. & W. Bristol, of 228 Sherlock Street, in the City of Birmingham,
Manufacturers and Inventors, do hereby declare the nature of this invention to be
as follows:-
This invention consists of the hereindescribed improvements in joints or
connections for connecting together rods or tubes of chimney sweeping machines,
drain and window cleaning apparatus, boring rods and other rods or tubes and for
connecting together the ends of wire ropes particularly where such wire ropes do
not have to pass round pulleys.
One form of our invention consists essentially of three parts namely two sockets
and one screw. The said sockets are respectively screwed or soldered or otherwise
fixed to the two ends of the tubes or rods or wire ropes which are required to be
connected together. The meeting ends of the sockets are formed to engage
together in such a way that if one socket turns the other will turn also; for instance
the ends of the sockets may have clutch teeth which engage together or one of the
sockets may have a square, polygonal or other end taking into a corresponding hole
or recess in the end of the other socket the said projecting end and hole or recess
being of such a shape that when the sockets are engaged together if one socket
turns the other socket will turn also. One of the sockets has an internal screw
fitting loosely therein the head of which screw is enclosed in the socket and the
screw shank of the same projects beyond the end of the socket and screws into the
other socket and thus secures the two sockets from pulling apart when they are
engaged together the clutch teeth or other shape of the ends of the sockets as stated
above preventing the sockets turning relatively to each other. There are openings
in that socket which is provided with a screw by which the screw head can be
turned to connect or disconnect the sockets.
When greater security is required there may be a cotter pin or screw fixed in
the head of the screw from the outside of the socket so as to effectually lock the
screw and prevent the same turning round in the socket.
In a modification of this invention the meeting ends of the sockets are made to
engage together as stated above but instead of the loose screw being employed the
said screw is formed in a piece with one of the sockets and projects from the end of
the same and enters the hole in the other socket and is there secured by a nut
enclosed in the last named socket which nut is turned and screwed on to the screw
through the said side openings in the socket.
The head of the screw or the nut above described may be made with holes for the
insertion of a small piece of wire or metal bar for turning the screw or nut when
connecting or disconnecting the joint or connection as stated above.

Improvements in Joints or Connections for Rods, Tubes, and
Wire Ropes.
We, JOSEPH WILLIAM BRISTOL, and WILLIAM WALTER BRISTOL, trading
together as J. & W. Bristol, of 228 Sherlock Street, in the City of Birmingham,
Manufacturers and Inventors, 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 :-
This invention consists of the hereindescribed improvements in joints or
connections for connecting together rods or tubes of chimney sweeping machines,
drain and window cleaning apparatus, boring rods and other rods or tubes and for
connecting together the ends of wire ropes particularly where such wire ropes do
not have to pass round pulleys.
We will describe this invention by referring to the accompanying drawing on
which
Fig. 1 is an elevation and Fig. 2 is a longitudinal section of a joint or connection
constructed according to this invention and shewn as connecting together the
adjacent ends of two rods;
Fig. 3 shews the parts of the said joint or connection separately; Fig. 4 shews a
slightly modified form of the same;
Fig. 5 is a sectional elevation of a further modification and
Fig. 6 shews separately the parts of the joint or connection illustrated by Fig. 5.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.
One form of our invention which is illustrated by Figs. 1, 2 and 3 and also by
Fig. 4 consists essentially of three parts namely two sockets marked respectively A
and B and one screw C. The socket A is fixed by any convenient means as by
the cross pin d to the end of the rod e and the socket B is similarly fixed to the end
of the other rod f. The meeting ends a¹¹ of the sockets A B are formed to engage
together in such a way that if one socket turns the other socket will turn also; for
instance the socket B may have a square end 1 (or a polygonal or other end)
which takes into a corresponding hole or recess a¹ in the end of the other socket A
the projecting end and the hole or recess a' being of such a shape that when the
sockets A B are engaged together as shewn in Figs. 1 and 2 if one socket turns the
other socket will turn also. The socket A is provided with an internal screw C
fitting loosely therein the head c' of this screw being enclosed in the socket A and
taking against the shoulder a and the screw shank c¹ of the screw C projecting
through the hole a and beyond the end of the socket and screwing into the screw
threaded hole in the other socket B, thus securing the two sockets from pulling
apart when they are engaged together as shewn by Fig. 2 the shape of the ends b'a¹
of the sockets as stated above preventing the sockets from turning relatively to each
other. There are openings a² a³ in the socket A by which the screw head e' can be
turned to connect or disconnect the sockets.
It will be evident that without departing from the nature of this invention the
ends of the sockets may be constructed in many different ways so as to engage
together and prevent one socket turning without the other socket; for instance as
shewn by Fig. 4 the meeting ends of the sockets A B may be made with clutch
teeth. In this case the socket B is made with two clutch teeth marked 63 which
engage between two corresponding clutch teeth a' formed on the socket A.
In order to prevent any possibility of the screw shaking loose after the two
sockets have been connected together there may be a cotter pin or screw (not
shewn on the drawing) fixed in the head of the screw C from the outside of the

page_text: socket A so as to effectually lock the screw C and prevent the same turning round
in the socket.
In the modification of this invention shewn by Figs. 5 and 6 the meeting ends of
the sockets A B are made to engage together as stated above but instead of the
loose screw C being employed the said screw (in this case marked C') is formed in
a piece with the socket B and projects from the end of the same and enters the
hole a in the other socket A and is there secured by the nut G enclosed in the
socket A which nut is turned and screwed on to the screw C' through the side
openings a a³ in the socket .A..
The head of the screw C or the nut G above described may as shewn be made
with holes c³ for the insertion of a small piece of wire or metal bar for turning the
screw C or nut D when connecting or disconnecting the joint or connection as
stated above.
'
The joints or connections above described and illustrated by our drawing are
applicable for connecting together all kinds of rods or tubes of chimney sweeping
machines, drain and window cleaning apparatus, boring rods and other rods or tubes
and for connecting together the ends of wire ropes particularly where such wire
ropes do not have to pass round pulleys. When our joints or connections are used
for connecting together the ends of wire ropes the sockets A B are made rather
longer than shewn upon the drawing and the ends of the wire ropes are fixed in the
sockets by soldering or by other convenient means.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In joints for connecting together the rods or tubes of chimney sweeping
machines and drain and window cleaning apparatus boring rods and other rods or
tubes and for connecting together the ends of wire ropes, the employment of
two sockets adapted to be fixed on to the ends of the rods tubes or wire ropes
and constructed substantially as set forth so that their meeting ends will engage
and turn together in combination with a screw which is partly and loosely
contained within one of the sockets and will screw into the other socket, the said
socket containing the screw having side openings to allow of the head of the screw.
being turned to connect and disconnect the two sockets, substantially as herein before
described with reference to Figs. 1, 2, 3 and 4 of the accompanying drawing.
2. In joints for connecting together the rods or tubes of chimney sweeping
machines and drain and window cleaning apparatus boring rods and other rods or
tubes and for connecting together the ends of wire ropes, the employment of two
sockets adapted to be fixed on to the ends of the rods tubes or wire ropes and
constructed substantially as set forth so that their meeting ends will engage and
turn together in combination with a screw formed with and projecting from the end
of one of the sockets and adapted to pass through a hole in the other socket which
last named socket contains a nut adapted to screw on to the said screw this latter
socket being also made with side openings to allow of the said nut being turned to
connect and disconnect the two sockets, substantially as hereinbefore described with
reference to Figs. 5 and 6 of the accompanying drawing.
