PROVISIONAL SPECIFICATION.
Improvements in the Bearings of Washing, Wringing, Mangling,
and similar Machines.
I WILLIAM LITLER BRADFORD of The Crescent Iron Works, Salford, in the
County of Lancaster Laundry Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to bearings for the axles or spindles of rollers and other
rotating parts and is more particularly applicable to domestic wringing and
mangling machines actuated by hand power.
Hitherto the bearings in which the spindles of the rollers of such machines
work have either been formed or cast in the frame of the machine or have
been in the form of blocks capable only of a sliding movement in slots' or
grooves.
I propose to fit the bearing blocks in slides, so that for example in the case of a
wringing machine in which the blocks for the rollers are mounted in vertical slides
the upper roller can rise or fall and its axis be retained in its required position
above that of the lower roller.
My invention consists in so rounding the outside of the top bottom and sides of
the bearing blocks, and abolishing the usual guiding flanges, that they are free to
adapt themselves to any reasonable variation in the direction of the axes which
they support due to want of truth in the framework, bed, or flooring, or to any
other cause; and thus the spindle shaft or axle will lie truly and without undue
friction in its bearings.
The slide of the frame holds the block so that the central vertical line which is
in the centre of the length of the said block or bearing remains constant (or
practically so) in any desired position.
I propose to fix a small snug or ear (or more than one) upon the block which
will rest against the side of the frame and prevent end wise motion of the block in
one direction; a boss roller or other fixture upon the axle or spindle passing
through the block preventing end wise motion in the other direction.
Thus in the case of a pair of wringing rollers mounted in bearing blocks one
above the other, I form or fix a snug ear or projection of the blocks for the
upper roller at either side of the axial line of the said blocks, and for the lower
roller bearings I form or fix a snug ear or projection on the underside thereof.
These snugs rest against the inner side of the frame and are round where they
touch the latter so as not to interfere with their freedom of action above
described.

I WILLIAM LITLER BRADFORD, of The Crescent Iron Works, Salford, in the
County of Lancaster, Laundry Engineer, 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 relates to bearings for the axles or spindles of rollers and other
rotating parts and is more particularly applicable to domestic wringing and
mangling machines actuated by hand power.
Hitherto the bearings in which the spindles of the rollers of such machines
work have either been formed or cast in the frame of the machine or have
been in the form of blocks capable only of a sliding movement in slots or
grooves.
I I propose to fit the bearing blocks in slides, so that for example in the case of
a wringing machine in which the blocks for the rollers are mounted in vertical
slides the upper roller can rise or fall and its axis be retained in its required
position above that of the lower roller.
My invention will be readily understood from the following description on
reference to the accompanying drawings.
Fig. 1 is a side elevation of so much of a wringing and mangling machine as is
necessary to illustrate my invention.
Figs. 2 and 24 shew respectively a face view and plan (in section) of the upper
bearing block and
Figs. 3 and 34 shew front view and plan of the lower bearing block.
My invention consists in so rounding the outside of the top or bottom (or both
as the case may be) and sides of the bearing blocks (see a and b on the drawings)
and abolishing the usual guiding flanges, that the said blocks (a and b) are free to
adapt themselves to any reasonable variation in the direction of the axes (say c
and d) to which they are applied due to want of truth in the framework, bed, or
flooring, or to any other cause; and thus the spindle shaft or axle (cor d for
example) will lie truly and without undue friction in its bearings.
The slide of the frame holds the block so that the central vertical line which is
in the centre of the length of the said block or bearing remains constant (or
practically so) in any desired position, say at the point at and 6+ respectively on
Figs. 2 and 34.
I propose to fix a small snug or ear (or more than one) upon the block which
will rest against the inside of the frame and prevent end wise motion outwards of
the block; and thus by preventing such block from moving outwards I can retain
the roller by its boss, collar, or shoulder, in its correct central position.
block
a,
Thus in the case of the pair of wringing rollers shewn at Fig. 1. provided with
bearing blocks a and b one above the other, I form or fix a snug ear or projection a
on the block a for the upper roller e at either side of the axial line of the said
and for the lower roller bearing 6 I form or fix a snug ear or projection b
on the underside thereof. These snugs a¹ b¹ rest against the inner side of the
frame g and are round or curved where they touch the latter so as not to interfer
with their freedom of action above described, but to prevent the bearings whe
they receive the thrust of the collars or shoulders of the rollers from being driver
to the outside of the slides and falling out of the latter. I prefer to form a snug b
at the front of the block 6 to prevent it from moving too far inwards and falling
from its slide when its shaft or axle d and roller f are removed.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is :-
The improved blocks or bearings for the shafts of wringing and mangling or
similar machines rounded and provided with snugs to prevent outward endwise
motion substantially as and for the purposes herein before set forth.
