Improved Pressure Regulating Mechanism for Wringing, Mangling,
and like Machines:
1, SAMUEL BARRETT of Crosshills near Keighley in the County of York,
Engineer and Machine Maker, do hereby declare the nature of this invention to be
as follows, that is to say :-
"
It relates to pressure regulating mechanism for the rollers of wringing, mangling
and like machines and consists of forming, constructing and arranging such
mechanism so that the necessary regulations may be readily effected while the
original or ordinary cost of production of the machine will scarcely be interfered
with.
In carrying my invention into effect I make use of the usual and well known
kinds of springs either of the flat or laminated or of the spiral class and these
springs I mount in such a manner that I am enabled to use cams for compressing
them, a cam, being mounted on each side of the machine so that its compressing
force will act directly upon its respective end of the roller.
These cams are mounted upon a shaft (preferably square in cross section)
extending across the machine so that by the movements of a handle fixed to one
or other of the ends of it both of these cams are operated simultaneously.
In order that each of these cams may regulate for varied degrees of compression
and be maintained in each of the positions in which it is placed, its peripheral
surface has flattened parts made upon it to rest upon the piece in connection with
which it operates while intervening beneath each of these cams and the roller
shaft are mounted small adjusting screws so that certain of the parts may be altered
or adjusted to meet the requirements caused by any differences in the diameters of
the rollers used in connection with them.
To keep the cams as small as convenient and so enable them to operate between
the bifurcations of the usual type of end frame such end frame is made to act as
guide for them in a lateral direction while a slot is made in the bearings to allow
their axial shaft to move laterally.
When spiral springs are used in connection with this arrangement of mechanism,
the cams have flanges cast or formed upon them to retain these springs and the
parts intervening between them and said cams, in position.

I SAMUEL BARRETT of Crosshills near Keighley in the County of York,.
Engineer and Machine Maker 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, that is to say :-
It relates to pressure regulating mechanism for the rollers of wringing, mangling
and like machines and consists of forming constructing and arranging such
machines so that the necessary regulations may be readily effected while the
original or ordinary cost of production of the machines will scarcely be interfered
with.
In the accompanying sheets of drawings,
Fig. 1. is a front elevation of so much of the machine as is necessary to shew
the application of my improvements.
Fig. 2. is an end elevation of part shewn by Fig. 1.
Fig. 3. is enlarged view shewing cam and lever."
Fig. 4. is enlarged view of part of Fig. 2.
Fig. 5. is a view shewing my improved mechanism applied to another kind of
machine.
In carrying my invention into effect 1 make use of the axial or well known kind
of springs either of the flat or laminated springs & or of the spiral springs p and
these mount in such a manner that I am enabled to use cams g for compressing
them, a cam 9 being mounted on each side of the machine so that its compressing
force will act directly upon the respective ends c¹ of the roller c. The cams a are
mounted upon a shaft c (preferably square in section) extending across the machine,
so that by the movement of the bandle f, fixed to one end of the shaft-e, both the
cams g are operated simultaneously.
C
In order that each of these cams y may regulate for varied degrees of com-
pression and be maintained in each of the positions in which it is placed, its
peripheral surface has flattened parts m made upon it to rest upon the pieces h in
connection with which it operates, while intervening beneath each of these cams g
and the roller shaft c', are mounted small adjusting screws which are fixed to the
piece and which screw into the parts and by this arrangement they can be
altered or adjusted to meet the requirements caused by any differance in the
diameter of the rollers c and d used in connection with them. To keep the cams y
as small as convenient and so enable them to operate between the bifurcations of
the usual type of end frames a and b, such end frames are made to act as guides
for them in a lateral direction while slots a' are made in the bearings to allow the
axial shalt e to move laterally.
When spiral springs p are used, the cams g are arranged with flanges g¹ cast or
formed upon them to retain said springs and the parts h in position.
In the arrangement as shewn by Fig. 5. in which the springs is used, I so
arrange the cans 9. and shaft e that they come on the underside of the bar t upon
which the springs rests, and at the same time the cams g come into contact with the
bearings of rollers.
By these means I can regulate the tension on rollers by moving the handle f
fixed on shaft e, the flanges g' keeping the cams g in position.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what I
claim is :-
1. The shaft e, the cams g, the handle, and the frames a and b, in combination

page_text: all being arranged in the manner and for the purpose as herein shewn and
described.
2. The shaft e, the handle f, the cams g having flattened parts m, the pieces h
having screws r, the parts & and the springs p all in combination, and arranged to
operate in the manner as shewn and described.
3. The frames a and b having slot holes a' arranged to receive the shaft e and
cams 9 as shewn and illustrated by the accompanying drawings.
4. The frames a and b, the shaft e, the handle f, the cams 9 having flanges 9',
the bar t and the springs in combination, the same being arranged in the manner
and for the purpose as described and illustrated by the accompanying drawings.
Dated this 16th day of January 1895.
