We, CHARLES LLOYD BRAITHWAITE and EDWARD O'BRIEN of the Firm of Isaac
Braithwaite and Son, of Kondal, in the County of Westmoreland, Merchants and
Engineers do hereby declare the nature of this invention to be as follows:-
This invention is primarily designed to strip the surplus starch off shirts and
other articles after coming from a starching machine particularly when using hot
starch as under such circumstances the articles are too hot to wring by hand.
In carrying out the invention we construct tho machine with an open end or with
the rollers supported at one end only.
The rollers are mounted in suitable bearings carried on pivoted bracket or brackets
which are caused to approach and recede as may be required to throw the rollers into
and out of contact with what may be described as a shears motion.
The spindles of the rollers extend beyond the journalled end and one is driven by
means of a strap and pulloy or other gearing one roller preforahly receiving motion
from the other when the two are brought into contact either by direct contact of the
rollers or by frictional or other gearing.
The bearings of one or both rollers preferably of the bottom roller are connected by
levers or links with a foot or other lever preferably a pedal to be operated by the feet
by which they are thrown into and out of contact.
A suitable adjusting mechanism is attached or applied to the bearings of the movable
roller to make or keep the rollers parallel.
The mechanism is such that one or both rollers can be reversed as required by means
of a suitable gearing and reversing motion.
The rollers are preferably situated in a horizontal plane but may be placed in a
vertical or inclined plane if found more suitable than the horizontal position.
A wringing machine thus constructed will have a decided advantage in the matier
of convenience for taking work when it is not desired to operate upon the whole or
pass the whole of an article between the rollers. It will also be found safer on account
of being more under control as when the foot is taken off tho treadle one roller drops
or moves right away ont of gear and stops.
Dated this 18th day of August 1896.
We, CHARLES LLOYD BRAITHWAITE and EDWARD O'BRIEN, of the Firm of Isaac
Braithwaite and Son, of Kendal, in the County of Westmoreland, Merohants and
Engineers, do hereby declare the nature of this invention and in what manner the
[Price 8d.1

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:-
This invention is primarily designed to strip the surplus starch off shirts and other
articles after coming from a starching machine particularly when using hot starch as
under such circumstances the articles are too hot to wring by hand; though it may
be applied to the wringing of any other articles out of liquors.
It consists essentially in the construction and arrangement of the machine with an
open end or with the rollers supported at one end only so that the materials can be
inserted over the ends of the rollers and in the mechanism for supporting and adjusting
the rollers aud causing them to approach and recede as required.
It will be fully described with reference to the accompanying drawings.
Fig. 1. Front elevation.
Fig. 2. Side elevation (partly in section).
Fig. 3. Plan.
The machine is provided with any suitable construction of frame or stand A which
carries at its upper end a head B for carrying or supporting the rollers.
The lower roller D is mounted upon a shaft E which rotates in the fixed bearings C
of the top or head B. The shaft E is attached at one end of the roller and the
roller D overhangs the shaft and the framing at the other end.
The upper roller F is mounted upon a shaft G which rotates in bearings h in a
pivoted or swivelling bracket H. The bracket His pivoted upon a shaft or
spindle I placed at the back of the supporting head B which can be oscillated by
a foot lever or other device to cause the rollers to approach
or recede.
The lower roller D is driven direct by the driving pulleys M M' and the upper
roller F is driven by the spur wheels N one of which is placed upon the spindle L
about which the roller F oscillates.
In normal position the upper roller F is held out of contact with the lower
roller D by a spring O and is drawn down into contact when required by the foot
lever P and connecting rod p.
As the rollers are not required to rotate when not in contact it is designed that the
samo movement that draws the rollers D aud F together shall also move the strap
fork R and throw the strap from the loose pulley M to the fast pulley M' and
vice versa.
Tho strap fork slides to and fro on a bracket r and is operated by a bell
crank lever S pivoted to the frame or stand A. The lower end of the lever S is
moved up and down by the washers s' on the connecting rod p. In order to allow of
a greater movement of the rod p and the roller F than of the lever 8 and strap fork R
the upper washer is pressed down by a spring o considerably weaker than the
spring consequently when the foot lever P is pressed down the spring is
compressed considerably before the strap fork is moved and when the foot lever P
is released and the rod p raised again the rod travels some distance before the strap
fork is operated by the second of the washers &¹.
It will be obvious that the bottom rollor may be mounted in oscillating or movable
bearings and the top roller in fixed bearings, or the bearings of both rollers may be
made movable.
A wringing machine thus constructed will have a decided advantage in the matter
of convenience for taking work when it is not desired to operate upon the whole or
pass the whole of an article between the rollers. It will also be found safer on account
of being more under control as when the foot is taken off the treadle one roller moves
out of contact with the other and the machine is stopped.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. A wringing machine constructed with the rollers open or unsupported at one
end the upper or bottom roller being mounted in an oscillating or movable bracket
connected to a foot lever whereby the rollers are caused to approach or recede as
required substantially as described.

as described and shown.
