Improvements in the Construction of Roller Bearings for Washing,
Wringing, and Mangling Machines.
1, RAMSDEN BROOKSBANK, of Greengate, Keighley, in the County of York,
Machine Maker, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to certain improvements in the manner of mounting the
rollers forming the bearings, in such a manner that, they do not separate when the
curve of the shaft is between two rollers, but retain the same relative distance from
each other in all positions as they rotate around the shaft or axle.
accomplish my object in the following manner :-Each bearing block is recessed,
and a cap secured to one side thereof, and in the recess I place two collars in which
are bored a number of holes for the reception of the roller ends, the rollers being
placed in the recess between the said collars, thereby keeping the rollers the same
distance from each other in all positions, as they revolve around the revolving
shaft.

Improvements in the Construction of Roller Bearings for Washing,
Wringing, and Mangling Machines.
I, RAMSDEN BROOKSBANK, of Greengate, Keighley, in the County of York,
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 relates to certain improvements in the manner of mounting the
squeezing roller shafts or axles of washing and analogous machines, in bearings con-
structed for the utilization of rollers arranged to be held together in a novel manner,
so that they do not separate when the curve of the shaft or axle is between two
rollers but retain the same relative distance from each other in all positions as they
rotate around the shaft or axle when the latter is in operation; and consists in forming
a recess in each bearing block, and placing therein two collars in which are bored a
number of holes for the reception and support of the bearing rollers, as hereinafter
more fully described.
In the accompanying drawings Fig. 1 represents an end view of a portion of a
machine frame fitted with bearings constructed according to my invention. Fig. 2
an enlarged end view of my improved bearing block. Fig. 3 a transverse section
through the same. Fig. 4 a longitudinal section, with three rollers shown in the
supporting collars, the intermediate,rollers being removed to more clearly illustrate
the bearing, and Fig. 5 a view of one of the supporting collars.
Each pair of bearing blocks A, are placed between the usual jaw plates or arms B,
of the machine frame as hitherto, for carrying the squeezing rollers C; and recessed
in the interior of each block for the reception of a cage of rollers constructed in the
following manner.
Each block A is prepared with a hole near the centre, through which the roller
shaft or axle D passes the circumference of the recess at E in the said block being
made true and concentric with the before mentioned hole. In the recess is placed a
cage of rollers F, supported at each end by collars G, in which are bored a number of
holes H for the reception of the said rollers F; the diameter of the rollers F being
such, that the outer circumference of the cage of rollers is slightly less than the
diameter of the recess; and the inner diameter slightly larger than the diameter of
the shaft or axle; the said cage being kept in the recess by a cap J, which may be
secured in any convenient manner to one side of the bearing block A.
The shaft or axle D is supported in each bearing by the rollers F, so that on
operating the said shaft, the rollers not only revolve on their own axis, but around the
shaft and recess also, keeping the same distance apart in all positions; thereby

the shafts or axles being kept lubricated by the rollers F revolving in oil in the
recess.
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 :-
A bearing block in which is formed a recess for the reception of a cage of rollers F,
the rollers being combined with and supported at each end by a collar G, all being
arranged substantially in the manner shown and for the purpose described.
