1, WILLIAM SCHRIMSHAW, of Dolphin Lane, Boston, in the County of Lincoln,
Tailor and Cabinet Maker, do hereby declare the nature of this invention to be
as follows:-
My invention relates to washing machines of the kind in which two or more
fluted rollers are employed, and between which the garments or other articles to
be washed are passed.
The object of my invention is to construct a washing machine in such a manuer
that the fluted rollers can be readily removed.
In carrying out my invention I mount a large roller in suitable bearings in
blocks adapted to be secured to a tub, a slot being formed in one block to allow
the large roller to be removed, the said slot being covered by a hinged plate.
Above this large roller I mount two small rollers carried in bearings in blocks
adapted to slide on spriug bolts projecting up through the blocks of the lower
roller. On the heads of the spring bolts are thumb nuts, the removal of which
permits the upper rollers and their blocks to be taken off.
The heads of the spring bolts are preferably provided with wings sliding in
slots to prevent the said bolts from turning.

COMPLETE SPECIFICATION.
Improvements in Washing Machines.
I, WILLIAM SCHRIMSHAW, of Dolphin Lane, Boston, in the County of Lincoln,
Tailor and Cabinet 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 :-
My invention relates to washing machines of the kind in which two or more
fluted rollers are employed, and between which the garments or other articles to
be washed are passed.
The object of my invention is to construct a washing machine in such a manner
that the fluted rollers can be readily removed.
In carrying out my invention I mount a large roller in suitable bearings in
blocks adapted to be secured to a tub, a slot being formed in one block corre-
sponding to a slot in the side of the tub to allow the large roller to be removed,
the said slot being covered by a hinged plate. Above this large roller I mount
two small rollers carried in bearings in movable blocks controlled by spring-bolts
projecting up through the blocks of the lower roller. On the outer ends of the
spring-bolts are thumb-nuts, the removal of which permits the upper rollers and
their blocks to be removed.
The heads of the spring-bolts are preferably provided with wings sliding in
grooves to prevent the said bolts from turning.
To enable my invention to be fully understood 1 will describe how it can be
carried into practice by reference to the accompanying drawing, in which :—
Figure 1 is a vertical section of a washing tub fitted with a washing machine
constructed according to my invention.

page_text: Figure 2 is an elevation of the right hand side of Figure 1 but only showing a
portion of the tub; and,
Figure 3 is a cross section on line A B of Figure 1.
a is a washing tub of ordinary construction.
b is the large fluted roller which I mount in bearings formed in the blocks c and d
adapted to be secured to the sides of the tub a, the bearing for the left hand end
of the roller consisting of a hole while that for the right hand or handle end
consists of a slot corresponding to the slot e in the side of the tub a to enable the
roller to be lifted out of its bearings; is the plate which covers in the slot e,
such plate being hinged at g to the tub; h and are the two small fluted rollers
located above and engaging with the large roller b; j, j are the movable blocks in
which the small rollers have their bearings; k, kare the bolts provided with
springs, l, which spring-bolts by acting on the blocks j, j serve to constantly
keep the small rollers h, i pressed against the large roller b. The lower ends of
the bolts k are provided with heads a¹ having "wings m sliding in grooves n in
holes o in the blocks c, d in which the springs are located, the said springs being
compressed between the upper ends of the holes o and the bolt-heads a¹. The
upper ends of the bolts pass through the blocks j, j and are provided with thumb-
nuts p, p for regulating the compression of the springs and consequent pressure of
the rollers, the wings m preventing the bolts from turning. By removing the
nuts .P, P p the upper rollers and their blocks can be removed when required.
9 is the handle for operating the machine.
With this construction the springs 4, I allow the blocks j, j to oscillate or rock so
as to cause the top rollers and i to independently yield to admit of the passage of
the various thicknesses of clothes between them and the bottom or large roller_b.
Also great facility is afforded for the removal and replacement of the rollers. To
remove them it is only necessary to unscrew the nuts p, p when the top rollers h
and i and the moveable blocks j, j can be lifted out; by then raising the covering
plate upon its hinge g the large roller can be lifted out of its bearings in the
blocks c and d. It is obvious that the rollers are replaced by a reverse series of
actions.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a washing machine the combination with a roller adapted to be rotated
in fixed bearings of two other rollers mounted in movable blocks, and spring-bolts
arranged as set forth for allowing the said blocks to oscillate or rock while the
clothes are passing between the rollers, substantially as herein before described and
illustrated in the accompanying drawing.
2. The improved washing machine hereinbefore described and illustrated in the
accompanying drawing.
