Improvements in Springs and the Method of Applying Pressure to
the Rollers of Washing, Wringing, and Mangling Machines.
We, OLIVER BRADLEY, of Eagle Iron Works, Keighley in the County of York,
Foreman, and GEORGE WHALLEY, of the same place, Machine Maker, do hereby declare
the nature of this invention to be as follows:-
This invention has for its object, the application of spring pressure to the rollers of
washing, wringing, and mangling machines, in such a manner that the ordinary
cross bar or bow, with screw and arched spring are dispensed with, and springs
substituted therefor, capable of giving the necessary pressure to the rollers; but
constructed with a considerably less quantity of material than the ordinary arch spring
now in common use.
We accomplish our object in the following manner; In place of the ordinary cross
bar or bow, we secure a bar or plate, to the machine frames, and through the said
bar or plate, pass screws, the ends of which come in contact with dies prepared for the
reception of springs.
One end of the journal blocks for the top rollers may be somewhat wedge shaped to
receive the springs, which we place between the blocks and top dies; the springs
being so constructed that when the rollers are separated by the material passing
between them, the wedge shaped dies open the springs, which then apply pressure,
proportionate to the thickness of the material passing between the rollers.
Or in place of the wedge shaped blocks, we can accomplish our object by forming
one or more bosses on the top roller blocks, concentric or otherwise, with the roller
axle and mounting springs on the said bosses, so that when material is passed hetween
the rollers, the springs are compressed by contact with adjustable inclined blocks above
the rollers, or inclined strips below which as the rollers are separated cause the springs
to contract and thus apply pressure to the rollers.

We, OLIVER BRADLEY, of Eagle Iron Works, Keighley, in the County of York,
Foreman and GEORGE WHALLEY of the same place, 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:
This invention has for its object, the application of spring pressure to the rollers of
washing, wringing and mangling machines, in such a manner that the ordinary bar or
bow with screw and arched spring are dispensed with, and springs substituted therefor
capable of giving the necessary pressure to the rollers; but constructed with a
considerably less quantity of material, than the ordinary arch spring now in common
use; and consists in forming a portion of the top journal blocks wedge shaped to
receive the springs placed between the said blocks and adjustable caps, the springs
being so shaped, that when material is passed between the rollers the springs are
expanded or contracted and forced against some portion of the framework and thereby
apply pressure in proportion to the thickness of the material between the rollers: or
the springs may be applied to the top roller journal blocks, so that when material is
put between the rollers, the springs are compressed by inclined strips above or below
the rollers.
For the purpose of more clearly explaining our invention, we will refer to the
accompanying sheet of drawings, in which Fig. 1 represents a portion of a machine
frame sufficient to explain our invention. Fig. 2 is a section of the top journal block
and Fig. 3 another mode of applying our improved springs.
By our invention we dispense with the ordinary cross bar or bow and arched spring,
and substitute therefor a spring A at each end of the machine, each of the said
springs being compressed between an adjustable recessed cap B, held in position by an
adjusting screw and fixed cap B', bolted to the frame arms C, and a top journal
block D, formed wedge shaped somewhat as shewn by section Fig. 2 the springs A
being bent so that when placed inposition they fill or nearly so, the space E between the
frame arms or projections C, so that when the rollers are seperated by material passing
between them, the wedge portion of the top journal blocks D) open the springs A,
causing them to press against the sides of the frame arms or projections C, and thereby
apply pressure in proportion to the thickness of material passing between them.
Or in place of the wedge shaped journal blocks D, we can accomplish our object by
forming a boss G concentric or otherwise with the roller axle, and mounting a similar
spring. A thereon, which may project downwards as shewn by drawing, or in an
upward direction: in either case the springs A' are compressed by contact with the
adjustable inclines and blocks H, placed in suitable positions, so that pressure is

them.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The herein before described method of applying springs to the rollers of washing, and
analogous machines, substantially in the manner as shewn and described.
Springs curved substantially in the manner shewn and used in connection with the
top journal blocks and adjustable supports for the purpose hereinbefore described.
