Improvements in or applicable to Ironing Machines.
I EDWARD TAYLOR the younger, of the Firm of Thomas and Taylor, of
144 Shaw Heath Stockport in the County of Chester, Engineer, do hereby declare
the nature of this invention to be as follows:-
This invention relates to that class of ironing machines wherein a revolving
roller is used in combination with a semicircular or concave steam heated bed,
the said roller being provided with means for reversing the revolution thereof
and also with means for raising the same up off the bed, and lowering the same
when required.
The invention consists principally in the construction of a simple arrangement
of driving gear for effecting these objects, and also of means for preventing the
roller from being raised too high and throwing the same out of gear to prevent
breakage if the gear should continue to revolve when the roller has reached its
lowest point.
According to my invention the driving end of the worm shaft for raising the
roller passes through a sleeve which is supported in suitable bearings.
On the outer end of this sleeve is keyed a bevil wheel gearing with two bevil
pinions set face to face upon a transverse shaft which is the main driving shaft of
the machine.
One of the said pinions is keyed fast upon the driving shaft, and the other pinion
is cast or keyed upon the boss of a driving pulley which I will call the "pinion
pulley" and which is loose upon the said shaft. There is a fast pulley also keyed
upon the said shaft and between these two pulleys is an idle or loose pulley.
These three pulleys are close together and all of the same diameter so that by
means of a sliding strap guide the driving strap may readily be moved from one
pulley to the other.
Upon the sleeve before mentioned there is also keyed or cast a spur pinion
which is geared with a spur wheel on the axle of the ironing roller or cylinder,
when in its working position but the spur wheel rises out of gear therewith as soon
as the roller commences to be raised from its bed.
Outside the spur pinion is the fixed half of a clutch-box, the sliding half of
which moves on a feather on the worm shaft.
From the above description it will be evident that when the driving strap is
placed upon the "pinion pulley" it will (by means of the sleeve) drive the roller
in one direction, and that when it is placed upon the fast pulley it will drive the
same in the reverse direction; and when the sliding half of the clutch box is
brought into action it will drive the worm shaft and raise or lower the ironing
roller according to the position of the driving strap.
In order to automatically prevent the ironing roller from being raised too high,
I fix a pin in the block or bearing which carries the roller axle, and to such pin
I fix one end of a chain which passes over a roller, and its other end is attached
by a bell crank to the strap fork lever, a certain portion of the chain being allowed
to haug slack. As the ironing roller rises this "slack" is taken up and as soon as
the chain becomes tight it pulls over the strap fork and puts the driving band onto
the idle pulley, and thus stops the further action of the machine.
And to throw the roller screws automatically out of action as soon as the roller
has reached its lowest position, place upon the same a nut which fits into a
corresponding recess in the boss of the worm wheel. As soon therefore as the
roller has reached its lowest position, if the worm wheel still continues to revolve,

page_text: the effect will be to raise this nut out of the recess in the boss of the worm
wheel and thus disconnect the two. The stop motion is therefore automatic in
both directions.

Improvements in or applicable to Ironing., Machines.
I EDWARD TAYLOR the younger, of the Firm..of Thomas and Taylor,
144 Shaw Heath Stockport in the County of Chester, 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:
This invention relates to that class of ironing machines wherein a revolving
roller is used in combination with a semi-circular or concave steam beated bed,
the said roller being provided with means for reversing the revolution thereof
and also with means for raising the same up off the bed, and lowering the same
when required.
The invention consists principally in the construction of a simple arrangement
of driving gear for effecting these objects, and also of means for preventing the
roller from being raised too high and throwing the same out of gear to prevent
breakage if the gear should continue to revolve when the roller has reached its
lowest point.
The invention will be readily understood from the following description on
reference to the accompanying drawings.
Fig. 1 is a plan view of the frame and driving gear and Figs. 2 and 3 are
elevations of the two ends of an ironing machine of the above class with my
invention applied thereto. Fig. 1 shews a detached part hereafter more particularly
described.
a is the framing of the machine, b the roller and c the concave steam heated bed
above referred to. 6* are the screwed rods which support the roller bearings or
blocks 6 and are actuated by the worm wheels 6' and by worms 6 on the worm
shaft d.
According to my invention the driving end of the worm shaft d for raising the
roller passes through a sleeve e Fig. 1 (shewn also detached at Fig. 1A) which
is supported in suitable bearings.
On the outer end of this sleeve e is keyed a bevil wheel gearing with two bevil
pinions ffset face to face upon a transverse shaft g which is the main driving
shaft of the machine.
"
The pinion is keyed fast upon the driving shaft, and the pinion f³ is cast or
keyed upon the boss of a driving pulley which I will call the "pinion pulley
and which is loose upon the said shaft g. There is a fast pulley h¹ also keyed
upon the said shaft g and between these two pulleys h and h¹ is an idle or loose
pulley h. These three pulleys h³ ³ are close together as seen on Figs. 1 and 3
and all of the same diameter, so that by means of a sliding strap guide i the
driving strap not shewn on the drawings may readily be moved from one pulley
to the other.
Upon the sleeve e there is also keyed or cast a spur pinion ex which is geared
with a spur wheel k see Fig. 3 on the axle of the ironing roller or cylinder b
when in its working position but the spur wheel k rises out of gear therewith as
soon as the roller b commences to be raised from its bed.
Outside the spur pinion ex is the fixed half e' of a clutch box el e³, the sliding
half of which moves on a feather on the worm shaft d. Or instead of a spur

page_text: pinion and spur wheel a worm and worm wheel or other equivalent gearing may be
employed if preferred.
From the above description it will be evident that when the driving strap is
placed upon the "pinion pulley "h it will (by means of the sleeve e) drive the
roller b in one direction, and that when it is placed upon the fast pulley ' it will
drive the same in the reverse direction; and when the sliding half of the clutch
box is brought into action it will drive the worm shaft d and the ironing roller b
will be raised or lowered according to the position of the driving strap.
In order to automatically prevent the ironing roller from being raised too high
I fix a pin in the block or bearing & which carries the roller axle and to such
pin I fix one end of a chain m which passes over a roller n and its other end is
attached or connected by a bell crank o and links o' to the strap fork lever p a certain
portion of the chain m being allowed to hang slack as seen at Fig. 2. As the
ironing roller brises the "slack" is taken up and as soon as the chain m becomes
tight it pulls over the strap fork i and puts the driving band onto the idle pulley h³,
and thus stops the further action of the machine.
And to throw the roller screws * automatically out of action as soon as the
roller b has reached its lowest position I place upon the same a nut r which fits
into a corresponding recess in the boss of the worm wheel b³. As soon therefore
as the roller 6 has reached its lowest position if the worm wheel still continues
to revolve the effect will be to raise this nut rout of the recess in the boss of the
worm wheel and thus disconnect the two. The stop motion is therefore automatic
in both directions.
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. The improved arrangement of driving gear for ironing machines substantially
as hereinbefore set forth and illustrated by the annexed drawings.
2. The mechanism for preventing the ironing roller from being raised too high
substantially as herein before set forth and illustrated by the drawings annexed.
3. The mechanism for throwing the roller screws out of action as soon as the
ironing roller has reached its lowest position, substantially as hereinbefore set forth
and illustrated by the drawings annexed.
