Improvements in Anti-frictional Bearing Apparatus.
I, WILLIAM JOHN BREWER, care of Charles Mason Esquire, C.E. of
10 Lyndhurst Square, in the County of London, S.E. Civil Engineer do hereby
declare the nature of this invention to be as follows:
My invention relates to apparatus for minimising the friction in their bearings of
axles for rolling stock of railways or tramways or other vehicles or of axles of
pulley blocks and similar weight lifting gear, and consists in the connection of the
primary axle and the antifriction wheel or wheels by chains, ropes, or flexible bands,
instead of by direct contact as heretofore.
In carrying out my invention I fit or fix on the main bearing axle or spindle a
collar, having a concave surface or groove to receive the chain rope or flexible band
by which I suspend a larger antifriction wheel therefrom, or by which the said axle.
is suspended from a larger anti-friction wheel. The weight upon the main axle is
thus transferred to a slower running anti-friction wheel whose periphery is also
grooved or concave to receive and retain the said flexible rope, chain or band which
thus encircles the said collar and antifriction wheel.
The said concave face or groove may be indented or of any desired shape to suit
the form of the chain, rope or flexible band.
Where this apparatus is applied to rolling stock the bearings of the antifriction
wheel may be fitted into a bracket or frame carrying any desired form of spring
between the body of the vehicle and the said bracket or frame..
The antifriction wheel may also in such case be suspended below the carrying
axle, but in the case of pulleys, may be above the main axle.
In case of any accident by the breaking of the chain, rope, or flexible band,, I
arrange that the carrying axle shall drop into fixed safety bearings so that no
delay or danger to the continued travel of the car or vehicle shall be thereby
occasioned.
One side and flange of the anti friction wheel may be removable to facilitate. the
placing on or removal of the chain rope or band.
The usual antifriction ball bearings or further anti friction wheels may be applied
to the pin or axles of the antifriction wheel which may preferably be fixed to or
solid with the said wheel and revolve in suitable bearings.

Improvements in Anti-frictional Bearing Apparatus.
1 WILLIAM JOHN BREWER, care of Charles Mason, Esquire,., CE. of
10, Lyndhurst Square, in the County of London, S.E., Civil 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:-
My invention relates to apparatus for minimising the friction in the bearings of
axles for rolling stock of railways.or tramways.or other vehicles or of axles of
pulley blocks and similar weight lifting gear and consists in the connection of the

page_text: primary axle and the anti-friction wheel or wheels by chains ropes or flexible bands
instead of by direct contact as heretofore.
In carrying out my invention I fit or fix on the main bearing axle or spindle a
collar having a concave surface or groove to receive the chain rope or flexible band
by which I suspend a larger anti-friction wheel therefrom or by which the said
axle is suspended from a larger anti-friction wheel that is the arrangement may be
inverted. The weight upon the main axle is thus transferred to a slower running
anti-friction wheel whose periphery is also grooved or concave in like manner to
the main bearing axle to receive and retain the said flexible rope chain or band
which thus encircles the said collar and anti-friction wheel.
The said concave faces or grooves may be indented or of any desired shape to suit
the form of the chain rope or flexible band.
Where this apparatus is applied to rolling stock the bearings of the anti-friction
wheel may be fitted into a bracket or frame carrying any desired form of spring
between the body of the vehicle and the said bracket or frame.
The anti-friction wheel is in such case suspended below the carrying axle but in
the case of pulleys is above the main axle.
In case of any accident by the breaking of the chain rope or flexible band I
arrange that the carrying axle shall drop into fixed safety bearings so that no
delay or danger to the continued travel of the car or vehicle shall be thereby
occasioned.
One side and flange of the antifriction wheel may be removable to facilitate the
placing on or removal of the chain rope or band.
The usual antifriction ball bearings or further antifriction wheels may be applied
to the pin or axle of the antifriction wheel which may preferably be fixed to or be
solid with the said wheel and revolves in suitable bearings.
In order that the said invention may be well understood I have annexed hereto a
sheet of drawings illustrative thereof and will refer thereto in the following
description by figures and letters like letters referring to similar parts in all the
figures.
In the drawings there is represented the means for the application of this
invention to a car-axle and bearings.
Fig. 1 is a side view of the axle and bearing parts which are arranged below the
side framing of the car.
Fig. 2 is a transverse central section at line A. B. of Fig. 1.
Fig. 3 illustrates the safety appliance which will become operative in the event
of fracture to the chain wire rope or band.
Fig. 4 shows in diagram a modification of said safety provision or device.
a is the main bearing axle or spindle with collar or collars 6 having a concave
surface or groove b¹ to receive the chain rope or flexible band c by which I suspend
a larger anti-friction wheel d therefrom. The weight upon the main axle is thus
transferred to the slower running antifriction wheel d whose periphery is also
grooved or concave in like manner to the main bearing axle a to receive and retain
the said flexible rope chain or band c which thus encircles the said collar and
antifriction wheel.
Where this apparatus is applied to rolling stock the bearings of the antifriction
wheel may be fitted into a bracket or frame carrying any desired form of spring
such as is shewn ate between the body framing of the vehicle and the said bracket
or frame g.
In case of any accident by the breaking of the chain rope or flexible band, I
arrange as shewn in Figs. 3 and 4 that the carrying axle shall drop into fixed safety
bearings h formed in a prolongation of the boxing i so that no delay or danger to
the continued travel of the car or vehicle shall be thereby occasioned.
In Fig. 3 the safety bearing will consist of the roller and prolongation of the
boxing and the journal of the roller as shown. In Fig. 4 the safety bearing will be
without the roller but be formed as a concavity h¹ in a strap piece h² constituting
the prolongation of the boxing i.

page_text: 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 :
First. In antifrictional bearings such as herein described the combination of the
main axle a and antifriction wheel d'carried upon the bracket or frame g with the
connecting and suspending chain or band c constructed and operating substantially
as and for the purpose herein set forth.
Secondly. In combination with the combined arrangement of antifrictional
bearings as claimed under the first head of claim the prolongation of the bracket or
boxing carrying the safety bearing roller as herein described in reference to and
shown by Fig. 3 of the drawings.
Thirdly. The modification of the safety
within and supported by the strap piece
shown by Fig. 4 of the drawings.
