IMPROVEMENTS IN FLEXIBLE CONNECTIONS OF STEAM PRESSES
Year: 1886

page_text: We FRED CRAVEN, of Phoenix Works, Brighouse, in the County of York,
Machine Maker, and BENJAMIN SUTCLIFFE, of Ginpit Hill, Clifton, in the County
aforesaid, India Rubber Merchant, do hereby declare the nature of our said
invention for IMPROVEMENTS IN FLEXIBLE CONNECTIONS OF STEAM PRESSES " to
"
be as follows:-
This invention relates to the pipes which connect the steam supply pipes with
the steam or press plates.
Heretofore the connecting pipes have consisted of metal tubes or pipes provided
with elbow and other screw joints so as to permit of the movement of the press
plates but such connections are expensive in construction and liable to breakage-
Other connections have consisted of flexible bone or india rubber tubing but the
heat and contact of the metal pipe within the tubing together with the movement
of the tube have soon destroyed the latter.
Now the object of this our invention is to construct the joint of and connect
flexible tubing with the steam supply and steam press plates so as to protect the
tubing from actual contact with the steam pipes and prevent the action of heat
and motion damaging the said connecting pipes as above explained.
According to this our invention we employ a short length of india rubber tubing
or sheet a part of which is slipped on the end of the steam pipe and covered by a
layer of asbestos fibre or asbestos cloth the latter is then covered by a wrapping of
woollen cloth or woven fabric-The protruding length of the tube is then folded
back and over the wrapping described which form practically a nonconductor of
heat and over which wrappings the ends of the flexible connecting pipe are passed
and on which they are secured-There being no contact between the steam pipes
and the steam flexible .conductors and which are free to move at the point of
juncture with the wrappings without injury or liability to cracking and breakage
as heretofore.

Improvements in Flexible Connections of Steam Presses.
We, FRED CRAVEN of Phoenix Works Brighouse in the County of York
Machine Maker, and BENJAMIN SUTCLIFFE of Ginpit Hill, Clifton, in the County
aforesaid India Rubber Merchant do hereby declare the nature of our invention
for "IMPROVEMENTS IN FLEXIBLE CONNECTIONS OF STEAM PRESSES and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
"
This invention relates to the pipes which connect the steam supply and
discharge pipes with the steam or press plates.
Heretofore the connecting pipes have consisted of metal tubes or pipes provided
with elbow and other screw joints, so as to permit of the movement of the
press plates, but such connections are expensive in construction and liable to
leakage.
Other connections have consisted of flexible bone or india rubber tubing but the
heat and contact of the metal pipe within the tubing, together with the movement
of the tube have soon destroyed the latter.
Now the object of this our invention is to construct the joint of and connect
flexible tubing with the steam supply and outlets and steam press plates so as to
protect the tubing from actual contact with the steam pipes, and prevent the
action of heat and motion damaging the said connecting pipes as above explained.
According to this our invention we employ a short length of india rubber tubing
or sheet, a part of which is slipped on the end of the steam pipe and covered by a
layer of asbestos fibre or asbestos cloth, the latter is then covered by a wrapping of
woollen cloth or woven fabric.
The protruding length of the tube is then folded back and over the wrapping
described, which form practically a nonconductor of heat, and over which wrappings
the ends of the flexible connecting pipe are passed, and on which they are secured.
There being no contact between the steam pipes and the steam flexible conductors
and which are free to move at the point of juncture with the wrappings without
injury or liability to cracking and leakage as heretofore.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings
forming a part of this Specification in which Figs. 1 and 2 are front views (partly
in section) of our improved connection.
According to this our invention to connect the india rubber steam pipe 1 to the
inlet steam and water pipe 2 and the press plates 3 we proceed as follows;
Over the brass or other metal tube 4 we place an india rubber tube 5 of such
length as shall leave a short piece overhanging the end of the said tube 5, we next
wrap round and over the india rubber tube some asbestos fibre or asbestos cloth 6
over which we place woollen or other cloth 7 or any other nonconductor of heat.
The overhanging part of the tube 5 is now turned back over 6 and 7, and the
enlarged end 8 of the india rubber steam tube 1 is pushed or drawn over all the
several pieces 4, 5, 6, and 7. It will thus be seen that the joint is quite water and

page_text: steam tight by reason of the india rubber 5 binding on the brass tube 4 and the
enlarged end 8 binding on the outside of the same india rubber 5, and also that
the india rubber tube 1 is not liable to leak or crack because of the non burning
asbestos cloth or fibre 6, and non-conducting of heat material 7 being placed between
the inlet steam pipe 5 and the said enlarged end 8 of the steam pipe or tube 1.
The enlarged end 8 of the tube 1 also acts as a sort of hinge and when the press
plates 3 are rising or falling as the case may be, the tube Ĭ is not liable to crack
or tear.
Instead of the india rubber tube 5 we may use an india rubber ring 5^ as shewn
in Fig. 2 having a recess 5B formed on its inner side for the reception of cloth, saw
dust, or any other non-conductor of heat.
•
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed we declare that what
we claim as our Invention is;
The construction of joints of pipes for purposes herein referred to, in manner
and by use of appliances and materials as herein fully described and illustrated by
drawings.
