PROVISIONAL SPECIFICATION.
An Improved Cavity Cylinder for Drying Textile Yarns
and Fabrics.
JACOB BRIDGE Paradise Works Accrington Engineer, Machinist, Ironfounder,
Tin Plate Worker, & Coppersmith do hereby declare the nature of this invention to be
as follows:-
This improvement relates to the ends or sides of cavity or double cylinders, that is
cylinders having an inner & outer rolled metal bodies for drying textile yarns & fabrics.
Hitherto these ends have been made of sheet or rolled metal & fastened to the bodies
of cylinders by means of solder. In this new system the ends or sides may be of
either cast or sheet metal, and the method of securing them is by means of bolts or
screws. A flange is thrown off the outer as well as the inner body. The end or side
is then brought on one side of these flanges, and a cast or wrot metal ring on the other
sides of these flanges. Between these surfaces the bodies of cylinder are held secure
by means of bolts or screws, thus forming a steam tight joint.

COMPLETE SPECIFICATION.
An Improved Cavity Cylinder for Drying Textile Yarns
and Fabrics.
JACOB BRIDGE Paradise Works Accrington Engineer, Machinist, Ironfounder,
Tin Plate Worker & Coppersmith 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 improvement relates to the ends or sides of cavity or double cylinders, that is
cylinders having an inner & outer rolled metal bodies for drying textile yarns & fabrics.
Hitherto these ends have been made of sheet or rolled metal & fastened to the bodies
of cylinders by means of solder. In this new system the ends or sides may be of
either cast or sheet metal, and the method of securing them is by means of bolts or
screws. A flange is thrown off the outer as well as the inner body. The end or side
is then brought on one side of these flanges, and a cast or wrot metal ring on the
other sides of these flanges. Between these surfaces the bodies of cylinder are held
secure by means of bolts, or screws, thus forming a steam tight joint.
In order that ny invention may be better understood, I will proceed to describe the
same inore particularly with the aid of the accompanying drawings.
Figure 1 is an end view of the cylinder, and
Fig. 2 an enlarged section of one of the cast iron ends or sides with the necessary
bolts, rings &c.
A is the cast iron end or side, B the wrot or cast iron metal rings, C the outer body
of cylinder, D the inner body, E the bolts that secure the bodies, and ends together,
F the bolts for securing the segments of ends together, G the cast iron arms or
spiders.
The object of this invention is to do away with the use of solder, or brazing in
securing the ends or sides of these cavity or double cylinders.
It will be seen on reference to the drawings, that the outer body C, and the inner
body D, are flanged or bent. On the outer side of these flanges, the end or side, A of
cylinder is placed, which may be in segments round the cylinder. On the other side
of these flanges are rings of cast or wrot metal, which may also be in segments round
the outer, and inside the inner body of cylinder as shewn. Bolts, studs, screws, or

page_text: rivets, may be employed for securing the two bodies of cylinder to the end A, and
these bolts, studs, screws or rivets, may pass from the end A, to the rings B, through
the bodies C and D, or vice versa, or may not pass through these bodies if we
sufficiently secure these two bodies between the rings B, and cast. iron end A without
passing them through, but in the drawing, these bolts are shewn as passing through
the rings, bodies, and ends.
Any packing substance may be employed in the above operations, as is usual in
making steam tight joints.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
1st. The application of screws bolts, nuts, or rivets as above described for securing
the ends or sides of cavity or double cylinders instead of soldering them.
2nd. The use of cast ends or sides, as well as rolled metal ends or sides.
3rd. The arrangement and combination of parts constituting the improved cavity or
double cylinder substantially as herein before described and shewn in the accompanying
drawings.
