Year: 1888

Specification Accepted, 5th Feb., 1889
I THOMAS CUDLIPP of 8 Church Street Edgware Road, Manufacturer of Laundry
machinery do hereby declare the nature of the said invention for "IMPROVEMENTS IN
COLLAR, OUFF, AND SHIRT IRONING MACHINES" and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
The improvements referred to, relato to certain classes of machines for ironing cuffs,
collars, shirts or other articles, in which ironing is effected by aid of a hollow roller
(heated internally with either gas, gasoline, steam, or any other suitable caloric) turn-
ing in bearings on the frame of the machine, beneath this roller is a cylindrical drum,
between which and tlie upper or ironing roller is an ironing board, to which a to
and fro, or reciprocating motion is imparted. In these machines one end of the
driving shaft (on which the fixed and loose pulleys are mounted) is provided with a
toothed wheel, gearing with a similar one of much larger diameter, mounted on the
shaft of the ironing roller, by which means, motion is transmitted from the driving
shaft to the ironing roller.
The object of my invention is to reduce friction, and simplify the machine, whilst
improving its construction and working capacity.
With this view I lengthen the shaft, either of the ironing roller, or of the drum for
carrying the driving and loose pulleys; by this means I do away with the driving
shaft and its bearings, as well as the toothed wheel and wheel of larger diameter on
the shaft of the ironing roller, as employed in machines of the type referred to, and
which forms the main feature of my improvements on such machines; by this means
lessening the cost of manufacture, simplifying construction, and increasing the
effective power of the machine.
In the accompanying drawings I have shown a plan of a machine of the
description to which my invention refers, and to which I have adapted my improve-
ments. In this drawing I have represented the fixed and loose pulleys as mounted
on the shaft of the ironing roller, but as above mentioned I mount these pulleys either
on this shaft, or on the dram's axis. The ironing table is removed for the purpose of
better showing the working parts of the machine-c is the ironing roller (heated

the frame a. The table as is customary in these machines, slides on guides g. g friction
between the table and guides being reduced by the rollers g. g. is the cylindrical
drum, between which and the ironing roller c, the ironing board moves to and fro.
The regulation of pressure on the article passed between the roller and the board,
is effected as heretofore by aid of a rod i, whose lower end is screw threaded and
screws into a projection on the frame. a.

Above or below the shaft of the ironing roller, or above or below the axis of the
drum, or on the drum itself, or on the rod / or in any other convenient position
I place a spiral or other spring, as an auxiliary means of assisting the raising and
lowering of the cylinder and fable above mentioned. The spring situated in any
one of these positions acts automatically in raising or lowering these axes, to
accommodate the varying thickness or inequalities of the articles under operation.
A hand wheel is mounted at the upper end of the rod, for turning it to
right or left, for either raising or lowering a swing frame. bearing the cylinder h,
and table as in the machines in use, is the driving shaft, bearing the fixed
and loose pulleys, and also the ironing roller c, carried in bearings on the frame
as hereinbefore stated as forming the main feature of my invention. A pinion m²
is fixed on the shaft c, which gears with a toothed wheel m³, mounted on the
shaft of the cylindrical drum, for importing motion thereto, the teeth of both
these wheels are of such a length as to admit of raising and lowering the frame
bearing the drum h, and table without interfering with the transmission of motion
between these wheels. A fixed pulley n, and two loose ones ¹², are mounted on
the shaft of the ironing roller c, as already described as forming part of my improve-
ments on these machines, these pulleys are connected with any suitable motor, by two
belts, one being open, and the other crossed, so that the driving pulley can be revolved
in contrary directions, by shifting the belts by aid of the belt fork as is customary
and well known.

The belt shifting apparatus I employ consists of the rods or arms p. p. adjustable on
the rod ¹, by means of sockets and adjusting screws 9: These rods at their ends are
forked . . for carrying the belts. The rod p is fixed to a collars, sliding backwards
and forwards on the shaft of the ironing roller (which in my improved machine
forms the driving shaft) this collar is also fixed to a bent rod t, sliding to and fro,
on the frame u, serving as guide to it, in its backward and forward movements. The.
rod is connected to a lever the lower end being fastened to a shaft carried in
bearings on the frame a, provided with a treadle u', as is customary with such
machines. A chain or cord is attached to a bracket on the rod, near its upper
end, and passes over a pulley mounted conveniently on the frame, a weight is
attached to the end of this cord, and by the alternate pressing down and rising
of the treadle, produces the alternate to and fro motion of the belt-shifter on the
shaft e¹ for shifting the belts as is well known for producing the requisite reversing
motion of the driving pulley, and consequently the reciprocating or to and fro
motion of the drums and ironing table.
In adapting my machine for shirt ironing I lower the drum, and its frame, and
mount a larger wheel on its axis to admit of the introduction of an auxiliary board,
so that the machine may thus be worked without the aid of additional pinions
and brackets.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is.
1st. In machines for ironing collars, cuffs, shirts, and other articles of the type
herein referred to, the novel method of mounting the driving and loose pulleys, either
on the shaft of the ironing roller, or the shaft of the drum, and in lengthening such
shafts for the purpose with the object of getting rid of the encumberance of the
driving shaft with toothed wheel, and bearings, as well as the toothed wheel of larger
diameter on the shaft of the cylindrical drum, thus reducing frictional parts,
simplifying construction, and effective power, with economy in cost of manufacture.

page_text: 2nd. Placing a spring or springs for the automatic regulation of pressure, either
above or below the shaft of the ironing roller or above or below the axis of the drum,
or on the drum itself, or on the rod i, or in any convenient position for producing the .
object desired.

3rd. The belt shifting apparatus consisting of the forkel rods or arms p. 2
adjustable on the rod pl, by means of the sockets and screws q'. The collar. and
bent or other shaped rod, t, sliding to and fro, on the frame u, or its equivalent, acting
as guide in its backward and forward movements.
4th. The method of lowering (bodily) the drum h, and its frame, and mounting a
larger wheel on its axis to admit of the introduction of auxiliary shirt ironing board,
thus obviating the necessity of employing additional pinions and brackets and so
simplifying construction and cost of manufacture, the whole in the manner by the
means and for the purposes herein set forth.
