Improvements in or connected with Machinery for Pressing and
Tentering Woollen and other Woven or Felted Fabrics.
I, WILLIAM BRADSHAW LEACHMAN of Excel Works, Great Wilson Street,
Leeds, in the County of York, Engineer, do hereby declare the nature of 'this
invention to be as follows:-
The object of my invention is to construct machinery whereby cloth may be
evenly and efficiently pressed, after being tentered or otherwise stretched.
According to my invention I employ a framework to which the tentering and
feeding mechanism is attached in any suitable way. Within this framework the
winding roller is mounted, which roller is driven or rotated by worm or other
suitable gearing.
At either end of the roller and situated on the framework, slides or guides are
provided, within which are mounted a pair of press beams having concave surfaces,
which run parallel to the winding roller before mentioned. To the backs of these
press beams are connected the ends of two double ended levers which are
fulcrummed at or about their centres to the framework of the machine. The lower
ends of the said double ended levers are connected respectively to a piston rod and
cylinder, which are actuated by steam or by other suitable power. The power
cylinder is provided with any convenient reversing gear, and the pressure within
the cylinder is regulated by a suitable reducing valve, which enables such cylinder
to exert any required amount of power.
By the employment of the above described arrangement, it will be seen that on
the application of power at the cylinder, the lower ends of the double ended levers
are forced outward, causing the upper ends to come toward each other, thereby
forcing the press beams against the opposite sides of the winding roller; so that,
as the cloth is being wound onto such roller after leaving the tentering portion of
the machine, it receives a regular and equal pressure along the full width
thereof.
When a piece of cloth of the required length has been wound and pressed on the
roller in the machine, the said roller is removed for the cloth to be allowed to
set," and another roller is inserted in the machine to receive another piece of
cloth for a like operation to that above described.
66
The press beams may be supplied with steam or other heating medium, whereby
the cloth is heated during the winding and pressing operation.
Instead of connecting the double ended levers respectively to the piston and
cylinder, I may when desired employ a stationary cylinder having two pistons,
the rods of which are connected to the aforesaid levers.

I, WILLIAM BRADSHAW LEACHMAN, of Excel Works, Great Wilson Street,
Leeds, in the County of York, 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 :-
The object of my invention is to construct machinery, whereby woollen and
other woven
or felted fabrics, hereinafter called cloth, may be evenly and
efficiently pressed after being tentered or otherwise stretched.
In order that my invention may be clearly understood, I will proceed to
describe same with reference to the accompanying drawings in which similar
letters refer to like parts in all the figures.
Figure 1 is a cross section of a machine constructed according to my invention,
and Figures 2 and 3, are respectively end and front elevations of the same
machine.
A, is a framework to which the tentering and feeding mechanism is attached in
any suitable way. B is the winding roller which is mounted in the frame A,
and the said roller B is rotated through the gearing C: D, D, are hollow press
beams, which are mounted in slides E, E, and to the backs of these press beams
the upper ends of the levers F, F, are connected, the said levers F, F, being
fulcrumed at G, G, on the frame of the machine. The lower ends of the
levers F, F, are connected respectively to a cylinder H, and piston rod J, which
are actuated by steam or other pressure, through the pipes H¹, and H2
reducing valve is employed for regulating the pressure imparted to the cylinder H,
and a handle L is provided for actuating the valve K, whereby the steam is
admitted to the cylinder through the pipes H¹, or H2, according as it is required
to press or withdraw the beams D, D. M, M, are pipes for supplying steam or
other heating fluid to the press beams D, D, and the cloth may thus be heated
during the pressing process.
A
When it is desired to press cloth in the machine above described, the cloth is
fixed in position as seen at Figure 1 and the gearing C is set in motion. The
handle L is then actuated, thus admitting steam through the pipe H2, which forces
the piston outwards and thus causes the lower ends of the levers F, F, to be forced
apart. The upper ends of the levers F, F, are thus brought towards each other,
thereby forcing the press beams D, D, against the opposite sides of the winding
roller so that, as the cloth is being wound onto the roller after leaving the
tentering portion of the machine, it receives a regular and even pressure along its
full width. When the piece of cloth has been wound and pressed on the roller in
the machine, the said roller is removed for the cloth to be allowed to "set," and
another roller is inserted in the machine to receive another piece of cloth for a like
operation to that above described.
Instead of connecting the double ended levers respectively to the piston and
cylinder, I may when desired employ a stationary cylinder having two pistons the
rods of which would be connected to the aforesaid levers at their lower ends. By
winding a sheet of paper with the cloth during the pressing operations the finish of
the cloth is greatly improved.
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 :-
1. A roller for receiving the cloth, in combination with two press beams for

forth.
2. The roller B, press beams D, D, levers F, F, cylinder H, and piston rod J,
substantially as and for the purposes set forth.
3. The combination of the various parts forming the machine before described,
whereby cloth, or cloth and paper may be pressed whilst being wound on the
roller B, substantially as and for the purposes set forth.
