Improvements in Cylinders for Drying Machines.
I, FREDERICK MASON, of Atlas Copper Works, Ramsbottom, in the County of
Lancaster, Tin & Copper Smith, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in cylinders for drying machines such as
are used by calico printers and the like.
Hitherto the nozzles have been generally attached to the cylinder ends by forming
the inner end of the nozzle with a flange, rivetting it to the outside of the cylinder
end and soldering over the ends of the rivets. This form of attachment is defective
as the said rivets soon work loose and when loose allow the steam to escape from the
interior of the cylinder, besides in order to render the cylinder steam tight again the
ends have to be removed which is a great source of trouble.
The object of my invention is to overcome the said defects and to this end I form
the said nozzles as hitherto with a flange, but instead of securing its flange against
the outside of the cylinder end I mount the nozzle in the centre or hole in the
cylinder end with its flange against the inside.
The part of the nozzle next to the outside of the cylinder end I form with a screw
thread and upon the saine place a nut by means of which the nozzle is tightly
clamped to the cylinder end.
In lieu of rivets I place bolts through holes formed in the nozzle flange and
cylinder end or I may use set screws engaging in screw threaded holes in the nozzle
flange, the said bolts and set screw being adapted to be drawn tight from the outside
of the cylinder so that if the said bolts or set screws should work loose in time, they
can be readily drawn tight again and thus the cylinder made steam tight without the
necessity of removing the cylinder end.
Hitherto the said rivets have been the sole support for the nozzle whereas in my
invention besides securing the nozzle flange to the cylinder end, the nozzle itself is
mounted therein thus providing double security.

improvements in Cynnuers for Drying machines.
I, FREDERICK MASON, of Atlas Copper Works, Ramsbottom, in the County of
Lancaster, Tin & Copper Smith, do hereby declare the nature of this invention and
5 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 improvements in cylinders for drying machines such as are
used by calico printers and the like.

page_text: Hitherto in drying machines of the type indicated the nozzles have been generally
attached to the outside of the cylinder ends, by forming the infer end of the nozzle
with a flange, rivetting it to the outside of the cylinder end and soldering over the
ends of the rivets. This formn of attaching is defective as the said rivets soon work
loose and when loose render the nozzle insecure, allow the steam to escape from the
interior of the cylinder and to render the cylinder steam tight again, the ends have
to be removed which is a great source of trouble and expense.
The object of iny invention is to overcome the said defects and consists chiefly in
forming the said nozzles as bitherto with a flange, but instead of securing its flange
against the outside of the cylinder end, I mount the nozzle in the centre hole of the
cylinder end, with its fange secured against the inside thereof.
And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures, Fig. 1 being a side view, Fig. 2 a longitudinal section,
and Fig. 3 an end view of a cylinder end and nozzle secured thereto in accordance
with my invention.
a is the cylinder end; b the nozzle and c its flange.
In carrying ont my invention, according to one form I furnish the part of the
nozzle b next to the outside of the cylinder end a with a screw thread b¹ and upon.
the saine place a nut ₫ by means of which the nozzle b is tightly clamped to the
cylinder end a in the centre hole.
The said nozzle I may secure to the cylinder end by rivets or bolts passed through
holes formed in the nozzle flange cand cylinder end a or preferably by set screws e,
as shown in the drawing, engaging in screw threaded holes in the nozzle flange c, the
said bolts or set screws being adapted to be drawn tight from the outside of the
cylinder so that in the event of working loose in time, they can be readily drawn
tight and thus the cylinder made steam tight again without the necessity of removing
the cylinder end.
If deemed necessary a suitable packing may be inserted between the outside of
the cylinder end and the heads of the set screws or the nuts of the bolts and also a
between the nut d and cylinder end.
Hitherto the Baid rivets have been the sole support for the nozzle whereas in my
invention, besides securing the nozzle flauge to the cylinder end, the nozzle itself is
mounted therein thus providing double security, in some cases the thread b¹ on
the nozzle and uut d may however be dispensed with.
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. In cylinders for drying machines, the method of attaching nozzles to cylinder
ends, consisting in mounting the tubular part of the nozzle concentrically in a hole 4
in the cylinder end and securing the nozzle flange against the inside of the cylinder
end, all substantially as set forth.
2nd. The nozzle, specified in the preceding clain, formed with a thread b¹ in
combination with a nut d, adapted to clamp the nozzle securely to the centre of the
cylinder end, all substantially as and for the purpose set forth.
