Improvements in Ironing Machines
Year: 1896

page_text: WILLIAM WARNER Hope Drive The Park Nottingham Civil Engineer do hereby
declare the nature of this invention to be as follows:-
This invention relates to ironing machines having a concave bed and roller.
The object of this invention is to provide a better means of lifting the roller and
lowering it into working position again.
As at present constructed the rollers are lifted by gearing driven by belt or hand
power with teeth wheels and worm screws.
This method is slow in action, there is considerable wear and risk of breakage.
My invention consists in lifting the roller by hydraulic power. I place the hydraulic
cylinder underneath the concave bed and for convenience attach it to the centre of
the bed. The ram is attached to a crosshead having joints with axles to support links,
and these links are also jointed to levers having a joint fulcrum, between the joint
and the ends, which are made to act upon the slides in communication with the
roller.
When the roller has to be lifted liquid pressure is conveyed inside the cylinder and
when the roller is lowered the pressure is let off by a valve.
Water, oil or any kind of suitable liquid may be employed and the pressure
obtained by pump or from a water main.

Improvements in Ironing Machines.
WILLIAM WARNER Hope Drive The Park Nottingham Civil 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 :-

page_text: The ram is attached to a crosshead having joints with axles to support links and
these links are also jointed to levers having a joint fulcrum between the joint and the
ends, which are made to act upon the slides in communication with the roller. When
the roller has to he lifted liquid pressure is conveyed inside the cylinder and when the
roller is lowered the pressure is let off by a valve. Water, oil, or any kind of suitable
liquid may be employed and the pressure obtained by pump or from a water main.
I will illustrate my invention by the aid of the accompanying drawings.
Figure 1 shews a front elevation of the machine.
Figure 2 shews a cross section through the roller concave bed & hydraulic
cylinder.
Figure 3 represents end elevation of the machine.
In all the figures like letters represent like parts.
The roller is marked a and the concave bed 6 the hydraulic ram c fitting the hydraulic
cylinder d, attached to the ram is the crosshead e fitted with links fjointed to the
levers having a joint fulcrum h.
The long end of the levers pass under the sliding blocks j which support the roller
at each end in a form of bottom bearing.
The top part of the slide frame & is made to allow the roller to lift a given distance
from the concave bed and holes are made near the top to allow resting pegs being
placed under the ends of the roller after lifting.
When the ironing machine is in use the roller is heated by steam passing through
the pipe m and the same pipe also supplies steam to the concave bed.
Similar pipes and also similar gearing to drive the machine as usually employed in.
ironing machines.
A small pump is placed at n having a water tank o and a pipe p to convey the
water at the back of the hydraulic ram. This pump is shewn to work by hand
but it is obvious that it may be worked by belt, gearing or steam power, and if
sufficient power can be obtained from the water main the pump may be dispensed
with altogether.
In some cases it may be more convenient to bave an hydraulic cylinder at each
end of the machine with supply pipes so that both ends of the roller may be lifted
together without the aid of levers.
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
In ironing machines hydraulic power for lifting the roller substantially as
specified with reference to and illustrated in the accompanying drawings.
