Improvements in and connected with Ironing Machines,
I, EDWIN JOHN LANE, of the Phoenix Engine Works, Cranbrook Street, Oll
Ford Road, in the County of London, Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in ironing machines for ironing skirts,
cuffs, and collars and the object thereof is to enable the pressure on the recipro-
cating table to be varied without altering the depth of gear of the teeth on the
driving wheel (which is usually keyed to the shaft of the driving drum) and of
the pinion on the ironing roller.
Now according to this invention I construct my improved ironing machine on
the usual plan that is to say it consists of a reciprocating table an ironing roller
above the table and a driving drum below it the said table being moved backwards
and forwards by being gripped between the said roller and drum the necessary
pressure being obtained by mounting the bearings of the drum shaft in a swing
frame one end of which is capable of being raised and lowered by a hand wheel
or other suitable means.
and screw
Hitherto it has been customary to key the spur wheel which drives the ironing
roller to the drum shaft consequently as the felt on the table becomes worn and
consolidated the driving drum has to he raised to maintain the pressure requisite
to drive the table and thereby put the teeth of the the said wheels too deeply in
gear or in other words to cause the pitch circles of the said teeth to overlap thereby
involving undue wear on the teeth and noisy running of the machine.
This defect I obviate as follows instead of keying the spu
spur wheel on the axle or
shaft of the driving drum I key the said wheel to a short shaft rotating in a
bearing in the frame of the machine and to the other end of the said shaft I key
a crank the pin of which engages with a block which slides in a slotted lever
keyed to the drum shaft so that no matter how much the swing frame is raised
or lowered the teeth of the driving wheel and pinion of the ironing roller always
remain in proper gear the bearings of the shafts carrying the said wheel and
pinion being supported by the rigid frame of the machine.
Or instead of using a separate shaft I may form the shaft of the driving wheel
in one piece with the said wheel.
Or instead of the slotted lever secured to the drum shaft I may use a crank and
connect the pin of the said crank to the pin of the crank on the spur wheel shaft by
means of a dry link.
Or I may secure the slotted link to the spur wheel shaft and the crank to the
drum shaft.

page_text: By this construction the gearing of the teeth of the wheel and pinion is unaffected
by the raising and lowering of the driving drum and the irregular motion of the
driving drum when the centres of the drum shaft and spur wheel shaft are not
coincident is not sufficient to affect the proper working of the machine.

COMPLETE SPECIFICATION.
Improvements in and connected with Ironing Machines.
I, EDWIN JOHN LANE, of the Phoenix Engine Works, Cranbrook Street, Old
Ford Road, in the County of London, 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 improvements in ironing machines for ironing shirts
cuffs and collars and the object thereof is to enable the pressure on the recipro-
cating table to be varied without altering the depth of gear of the teeth of the
driving wheel (which is usually keyed to the shaft of the driving drum) and of
she pinion on ironing roller.
Now according to this invention I construct my improved ironing machine on
the usual plan that is to say it consists of a reciprocating table an ironing
roller above the table and driving drum below the table the said table being moved
backwards and forwards by being gripped between the said roller and drum the
necessary pressure being obtained by mounting the bearings of the drum shaft
in a swing frame one end of which is capable of being raised and lowered by a
hand wheel and screw or by other suitable means.
Hitherto it has been customary to key the spur wheel which drives the ironing
roller pinion to the drum shaft consequently as the felt on the ironing table
becomes worn and consolidated the driving drum has to be raised to maintain the
pressure requisite to drive the table and thereby put the teeth of the said wheels
too deeply in gear or in other words to cause the pitch circles of the said teeth
to overlap thereby involving undue wear on teeth and noisy running of the
machine.
This defect I obviate as follows. Instead of keying the spur wheel to the axle
or shaft of the driving drum key the said wheel to a short shaft rotating in a
bearing in the frame of the machine and to the other end of the said shaft I key
a crank the pin of which engages with a block which slides in a slotted lever
keyed to the drum shaft so that no matter how much the swing frame is raised
or lowered the teeth of the driving wheel and pinion of the ironing roller always
always remain in proper gear the bearings of the shafts carrying the said wheel
and pinion being supported by the rigid frame of the machine.
:
Or instead of using a separate shaft I may form the shaft of the spur wheel
in one piece with the said wheel.
Or instead of the slotted lever secured to the drum shaft I may use a crank
and connect the pin of the said crank to the pin of the crank on the spur wheel
by means of a drag link.
Or I may secure the slotted lever to the spur wheel shaft and the crank to the
drum shaft.

page_text: By this construction the gearing of the teeth of the said wheel and pinion is
unaffected by the raising and lowering of the driving drum and the irregular
motion of the driving drum when the centres of the drum shaft and spur wheel
shaft are not coincident is not sufficient to affect the proper working of the
machine.
And in order that my said invention may be fully understood I will proceed
to explain the same with reference to the accompanying drawings in which:
Fig. 1 represents side elevation of an ironing machine constructed according
to this invention.
Fig. 2 is plan of swing frame and driving drum.
Fig. 3 is elevation of sliding block and lever.
The same letters denote the same parts in all the figs.
a is the main frame of the machine.
the pinion attached to the driving shaft b¹ which is provided with two pulleys
and a cone clutch gear in the usual way by means of which either pulley may
be locked to the driving shaft the pulleys being driven by open and crossed belts
enable the driving shaft to be rotated in either direction.
c is a spur wheel having a long boss c¹ rotating in a bearing & carried by the
portion e of the. frame of the machine.
f is the driving drug the drum shaft supported in bearings h h in the swing
frame i which in its turn is supported at jjat one end and by the hand wheel
and screw at the other end.
m is the ironing table n the ironing roller driven from the wheel c by
means of the pinion keyed to the roller shaft.
oo are rollers for supporting the ironing table.
The spur wheel c has a crank q attached thereto the pin of which engages with
a block sliding in the slotted levers keyed to the drum shaft g so that when
the felt on the ironing table becomes worn or consolidated and it is necessary to
raise the driving drum to obtain the requisite grip on the ironing table the depth
of gear of the teeth on the wheels bcp is unaffected by the movement of the
swing frame as the shafts to which the said wheels are attached are supported in
bearings formed in or attached to the rigid frame of the machine no shaft having
toothed wheels or pinions thereon being carried by the swing frame.
It is obvious that the crank attached to the wheel c may be connected to a
second crank on the drum shaft by means of a drag link instead of using a slotte:l
Jever and sliding block.
Or the slotted lever may be secured to the wheel e and the crank to the drum
shaft.
The difference in the velocity ratio of the drum f and wheel c when the centres
thereof do not coincide is not sufficient to interfere with the proper working of
the machine.
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. In an ironing machine supporting the spur wheel actuating the driving
drum by means of a long boss or shaft carried by one or more bearings forming
part of or attached to the frame of the machine and connecting the said boss or
shaft to the shaft of the driving drum by means of a crank and slotted lever two
cranks and a drag link or other suitable flexible connection all substantially as
hereinbefore specified and for the purpose stated.
2. In an ironing machine the combination of a spur wheel chaving a long
boss c thereon rotating in a bearing d, a driving pinion b gearing with the wheel c
a pinion driven by the wheel c, a swing frame i supported at jj and 7 and
carrying the drum shaft g, a crank 7 attached to the boss of the wheel c, a slotted
levers keyed to the shaft g and a sliding block r engaging with the pin of the

page_text: crank and sliding in the slotted lever s all substantially as hereinbefore specified
and for the purpose stated.
3. Ironing machines constructed as shewn by the accompanying drawings.
