page_text: We, CHARLES LLOYD BRAITHWAITE, ISAAC BRAITHWAITE, and EDWARD O'BRIEN,
of the Firm of Isaac Braithwaite and Son, of Kendal, in the County of West-
moreland, Merchants and Engineers, do hereby declare the nature of this inven-
tion to be as follows;
-
This invention is designed primarily to permit of the top or padded roller
being lifted or removed clear of the bottom or heated roller or rollers so that
access may be readily had to the latter.
The machine is constructed with one or two (preferably two) bottom heated
rollers and a top padded roller of larger diameter. The two bottom rollers are
geared to travel at different speeds the first one rotating more slowly than the
second one though with greater surface velocity than the padded roll.
The first roller thus acts as a drying roller upon the articles and the second
roller more particularly for ironing and polishing.
The bearings of the padded roller are supported upon levers or arms which can
be raised to carry this roller clear of the others. At each end of a back shaft are
fitted arms or levers upon which the padded roll is supported or by which it can
be lifted. A third lever upon the same shaft is operated by a screw working in
the frame or stay bar so that by rotating the screw the padded roller may be
lifted or lowered.
The end of this lever is formed with a hook or open slot which engages the
screw so that it may be rotated clear of the screw to enable the padded roller
to be lifted completely clear of the hot rollers. The padded roller when the
machine is in operation is held down by weights or springs.
The bottom rollers are preferably fitted with continuous self oiling bearings
by means of a chain passing over the journal and are driven by a train of gear
wheels or otherwise. The driving pinion is worked by a clutch from the driv-
ing pulley.
The top stay acts at one end as a pin or stud for the driving pinion and at
the opposite end acts as a catch for the lifting screw.
The bottom rollers are protected by a casing formed by a frame of wrought
iron bent into shape with rods or bars stretching across the machine and covered
with sheet brass or other metal leaving a slit for the articles to be fed through.
The frame is supported by catches or lugs so as to be easily removed and replaced.
A tray is placed below the rollers to catch the articles as they are ironed con-
structed of bent wood hooked over cross bars extending across the machine so
as to be readily and easily removable.

page_text: We, CHARLES LLOYD BRAITHWAITE, ISAAC BRAITHWAITE, and EDWARD O'BRIEN,
of the Firm of Isaac Braithwaite and Son, of Kendal, in the County of West-
moreland, Merchants and Engineers, do hereby declare the nature of this inven-
tion 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 gas heated roller ironing machines and is designed
primarily to permit of the top or padded roller being lifted out of contact with
the bottom or heated roller or rollers to give access thereto.
It consists essentially in constructing the machine with the top padded roller
journalled in bearings carried by a pivoted lever capable of being raised and
lowered, also with two bottom lieated rollers geared to travel at different speeds,
the first one travelling more slowly than the second. They may be made to travel
at the same speed.
It will be fully described with reference.to the accompanying drawings...

Fig. 2. Elevation of same from the back with bottom of frame omitted..
Fig. 3. Transverse section on line, Fig. 2.
IT
The top padded roller. A is carried in bearings a. in arms or levers. B. pivoted
to the side of the frame. C by which the roller A can be raised to lift it out. of
contact with the lower rollers. D &.E.
น
The levers B are secured upon the back shaft. b.and to. the same shaft is
attached a lever B₁ held or operated by a screw F. with a screwed hand wheel
or nut F. In the end of the lever is pivoted a loose washer or collar with
pivots or trunnions f¹ fitting into holes or into a hook or open slot f² formed
in the end of the lever. This permits of the screw being removed therefrom
and the arms or levers B and B being rotated to lift the padded rollér A entirely
clear of the heated bottom roller D & E.
When the machine is in operation the padded roller A is held in contact with
the rollers D & E and the desired amount of weight or pressure applied by the
weights or the levers a suspended by the rods. Instead of weights springs
may be employed to hold the rollers in contact.
The bottom rollers D & E are journalled in bearings & e in the frame C and
are heated internally by gas from the tubes or burners de. The roller D is
rotated at a slower speed than the roller E thus the first roller acts primarily as
a drying roller upon the articles and the second roller E finally irons and polishes
the articles. The rollers D and E may be heated by steam.
The
The rollers are driven by the driving pulley K connected thereto by a clutch K'
which is thrown into and out of gear with a fork and stop rod k
clutch K¹ is connected with the pinion L which with the clutch and driving pulley
run loose upon the central stay bolt G. The pinion L gears with and drives the
pinion M loose on the end of the roller E and to the pinion M is pinned or other-
wise attached the pinion Q which rotates with it.
The pinion M gears with and drives N and O attached together and running
loose on the back shaft b. N & O engages with and drives P fast or keyed to
the shaft of the padded roller A which is driven thereby.
The pinion Q which is loose on the shaft of the second bottom roller E gears
with the pinion R keyed on the shaft of the first bottom roller D and drives it
at the desired speed. Keyed to the same shaft is the pinion S and on the shaft
of the other roller E is keyed the pinion U of smaller diameter. Between the

page_text: two pinions S& U is a carrier wheel T with which both gear and by which the
roller E is driven in the same direction as the roller D and at a faster speed.
Instead of the clutch K₁ the machine may be driven by fast and loose pulleys.
The top stay bolt G at one end of the frame serves as a pin or stud for the
driving pulley K clutch K¹ and pinion K and at the other end to hold the lifting
8crew F.
The bottom rollers D & E are protected by a casing H formed by a frame of
wrought iron bent into shape with rods or bars H stretching across the
machine and covered with sheet brass or other metal leaving a slit ¹ for the
articles to be fed through. The frame is supported by catches or lugs so as to be
easily removed and replaced.
The bottom rollers are also preferably fitted with continuous self oiling bearings
in which chain passes over the journal in the usual way. A tray Jis placed
below the rollers to catch the articles as they are ironed constructed of bent wood
or sheet metal hooked over cross bars extending across the machine so as to be
readily and easily removable.
It is to be understood that the lifting or raising of the top padded roller A
may be applied to a machine with a single bottom heated roller and also that
the two bottom heated rollers rotating at different speeds may be applied to a
machine with a top padded roller fitted into fixed bearings.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, we declare that what
we claim is:
:
1. An ironing machine constructed with a top padded roller mounted or carried
in movable arms or levers capable of being lifted out of contact with and clear
of the heated roller or rollers substantially as described and shown.
2, In an ironing machine the combination with a top padded roller of pivoted
arms or levers capable of being raised and lowered in which the roller is jour-
nalled a lever or screw for raising the pivoted arms and padded roller and weight
or springs for holding the padded roller in contact with the heated roller or rollers
substantially as described and shown.
3. An ironing machine constructed with two heated rollers working in con-
junction with a single padded roller and rotating at different speeds the first more
slowly than the second substantially as described and shown.
4, In an ironing machine the combination with single top padded roller jour-
nalled either in fixed or moveable supports of two bottom heated rollers one
rotating at a quicker speed than the other and gear wheels or pinions for driving
the rollers arranged substantially as described and shewn.
5, An ironing machine having the several parts constructed and arranged in
combination substantially as described and shewn.
