The machine carcase is constructed of two frames E E upon standards F F kept
rigid by two rods or cross bars G G across the standards a few inches above the
bottom of the machine. Across the back of the frames runs a shaft H by which
the machine is driven, running in two bearings each held to each individual
frame by set screws. At the end of the above mentioned shaft are two pulleys I
& I¹ fast and loose & close to them are two spur wheels A & B one larger than the
other: A being nearest the pulleys. These small spur wheels A & B are keyed to
the shaft. A & B gear into two large spur wheels C & D which run
shaft K, which runs through the centre of the machine. A gears into C. B gears
into D. C & D vary in size according to A & B. C gearing into A is keyed or
fastened on the, shaft the other spur wheel D (being loose) besides gearing into
B gears into five other spur wheels L the same size as A. The five spur wheels L
being keyed to the journal ends M of the steel rollers P the journal ends of which.
run in the slide block bearing or journal N. On the shaft K is a large roller
covered with felt & cotton & running against the small rollers P they being kept
at a pressure on the large roller by the screws Q carrying the springs R which
are regulated to put pressure on the rollers by the nuts S. the other ends of the
screws Qbeing let into the journal boxes N. The shaft K runs in the journal
boxes TT which are highered or lowered to or from the small rollers P by the
two threaded spindles U U₁ these spindles being turned by the small hand
wheels u u. When is highered or lowered the distance from its centre K to
the centres of the two outside rollers are equal.
Any number of the rollers P can be used provided the angle between the two
outside rollers taking K as centre. does not get too large & prevent the spur
wheel D from leaving the teeth of the spur wheels L when the shaft K is lowered.
At the back of the small rollers P are put guides V to lead the article being
ironed to the next roller & and also to prevent it from curling round the small
rollers.
These rollers are heated either with gas jets or steam.
The pipes marked Z represent gas-piping through which the gas is led to the
rollers.
I can do away with the sour wheels C & B (see Sheet 3) & by gearing D into A
& keving D on the shaft K, I can get less slip between the rollers & P. The
extra gear is put on for the purpose of getting a large amount of slip between
O & P.
Figure 3 shows end view of a small roller: X are the holes through which the
air goes to make the gas burn & also to let foul air escane, & W shows the hole
|through which the gas piping goes to the inside of the roller.

page_text: Sometimes I heat the large roller with steam & the small rollers with gas, some-
times all with gas & sometimes all with steam.
I, JOSEPH APPLEYARD, Laundry Engineer, Harris Street, Bradford, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in machines for calendering or ironing
linen and the like.
To fully describe my invention reference is made to the accompanying sheet of
drawings forming a part of this specification in which Figure 1, represents a side
view of my improved machine. Figure 2, is a front view of the same and Figure 3,
is a similar view illustrating a modification.
The side frames E, E are mounted upon standards F, F rigidly connected to-
gether by the two cross bars G, G and the driving shaft H is mounted in bearing
brackets H2 secured to the side frames E. The driving shaft is provided with
fast and loose pulleys J and J2 and adjacent to them the two spur wheels A and B
aré keyed upon the shaft. The wheels A and B engage the toothed wheels C and
D the latter of which is loosely mounted upon the shaft K whilst the former is
keyed to and drives such shaft. The wheel D engages the pinions L keyed on the
projecting ends of the shafts M of the steel polishing or ironing rollers P the
journals of which run in the spring slide bearing blocks N. The shaft K carries
a drum or large roller O covered with felt and cotton cloth and when the drum
and shaft are raised to working position by the screws U engaging the sliding
bearing blocks of the shaft K the periphery of the drum runs in contact with the
peripheries of the rollers P. The screws are provided with hand wheels a or the
like and when the machine is not' in use the drum O is lowered out of contact with
the rollers P to keep it from being burnt. The rollers P are preferably heated
by gas supplied by the pipes Z. Any number of rollers P can be used providing
sufficient space is left between the two outside rollers to permit of the drum being
moved out of contact with them. The bearing blocks N are provided with screwed
studs projecting through holes in the flanges F3 of the frames E and springs R
on such studs are more or less compressed between the inside of the flanges and
the nuts S' on the studs according to the extent the rollers are required to press
upon the drum 'O. As the wheel D is larger than the drum O and the pinions I
are smaller than the rollers P the peripheral speed of the rollers is considerably
greater than that of the drum consequently there is efficient ironing action.
Cross guides V are fixed across at the back of each roller so as to just clear the
roller and guide articles being ironed from one roller to the other and prevent
them following the rollers round. The finished articles fall into the receiver e pro-
vided below. Or they may be carried round to the front by an endless apron. A
horizontal feed table i is preferably provided.
Instead of the screws U I may employ a treadle lever and cam arrangement for
raising and lowering the drum O.
When so great a difference in the peripheral speeds of the rollers P in relation
to that of the drum O is not required I can do away with the wheels C and A as

page_text: shown in Figure 3. In this case the wheel D is keyed on to the shaft K and
drives it.
The drum O is preferably internally heated by either by gas or steam.
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:-
1. The combination with the drum 0 of two or more rollers P each of which
is driven at a greater peripheral speed than the drum by a wheel D concentric
with the drum, substantially as herein shown and described and for the purpose
specified.
2. The combination of a drum O and a roller P respectively driven in the man-
ner shown in Figures 1 and 2, substantially as herein shown and described and
for the purpose specified.
3. The combination with the drum 0 of two or more rollers P and one or more
cross guides V, substantially as herein shown and described.
Dated this 1st day of November 1898.
