PROVISIONAL SPECIFICATION.
Improved Pressure Regulating Device for Wringing and Mangling
Machines.
I, HENRY CROFTS LONGSDON of the Firm of W. Summerscales and Sons
Limited, of Keighley in the County of York, Engineers and Machine Makers, do
hereby declare the nature of this invention to be as follows, that is to say :-
It relates to means for regulating the pressure applied to the rollers of wringing
and mangling machines and consists of arranging and constructing same so that the
two springs used in connection with these rollers, may be compressed equally and
simultaneously and by mechanism leaving the upper covering of the machine flat
and free to be used for well known purposes.
To attain this object I employ the usual and well known form of spiral springs,
one at each end of the upper roller, but instead of making one cross bar press upon
both of these springs, I arrange a lever to be carried by the framework, preferably
a cross rail, to press upon each spring separately.
These levers, however, are coupled together by a screwed connecting rod and
other parts so that on such rod being rotated the levers are moved to compress the
springs or to relieve them of such compression as the case may be as to whether
the rod is rotated in one or other direction.
The formation of the compression levers may be either of a simple bell-crank
type or they may be formed so that one of their arms is a cam to act on the springs
described.

Improved Pressure Regulating Device for Wringing and Mangling
Machines.
I, HENRY CROFTS LONGSDON of the Firm of W. Summerscales and Sons
Limited, of Keighley in the County of York, Engineers and Machine Makers, 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 means for regulating the pressure applied to the rollers of wringing
and mangling machines and consists of arranging and constructing same so that
the two springs used in connection with these rollers, may be compressed equally
and simultaneously and by mechanism leaving the upper covering of the machine
flat and free to be used for well known purposes.

of a machine to illustrate the application of my improved mechanism. The type
of machine in this case being strong and firm to enable its use in the pressing or
mangling of crude india-rubber or for similar other heavy work.
Figs. 3 and 4 are similar views to Figs. 1 and 2 respectively but show a modified
form of my improved mechanism and its application to a common wringing or
mangling machine for domestic purposes and are drawn to an enlarged scale as
compared with Figs. 1 and 2.
AA indicate the end frame of the machine and b c the upper and lower rollers
respectively.
To attain the object of my invention I employ the usual and well known form
of spiral springs de, one at each end of the roller b, but instead of making one
cross bar press upon both of these springs 1 arrange the levers ƒ and g to be
carried by the framework (preferably the cross rail ) to press upon each spring d
and e separately.
These levers fand 9, however, are coupled together by a screwed connecting
rod k and the swivel nuts m n (if both these nuts are screwed their threads must
lead in opposite directions the one being thus a right hand the other a left hand
thread, while those on the rod k are made to correspond. But this rod k may be
made to revolve freely in the nut m which at this time will only form its bearing,
and the thread alone formed in the nut n) so that on said rod k being rotated by
the hand wheels the levers fy are moved in the directions indicated by the
arrows p or in directions opposite to these, to compress the springs de or to relieve
them of such compression as the case may be as the rod k is rotated in one or other
direction as will be well understood..
The formation of the levers fg may be either of the simple bell crank type as
shown by Fig. 1, or they may be formed so that one of their arms f¹¹ (see Fig. 3)
is a cam to act on the springs d e as may be desired.
The cross rail may be of the form shown by Figs. 1 and 2 which form is
preferably used for the class of machine shown by these said figures or it may be
of the shape shown by Figs. 3 and 4 in which case it is most useful for domestic
purposes, while further, it covers the rod k and levers fg as shown.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
1. In pressure regulating mechanism for wringing and mangling machines, the
combination of levers with their rod and other connections arranged and formed
substantially as herein specified.
2. The combination in wringing and mangling machines of cam levers, rod and
screwed nut connections and means for supporting same substantially as herein
specified.
