Improvements in Anti-friction Bearings for Axles, Shafts, and the like.

page_text: PROVISIONAL SPECIFICATION,
Improvements in Anti-friction Bearings for Axles, Shafts, and the
like.
We, JOSEF CALCATERRA, of 35, Terminus Terrace, Southampton, Interpreter,
and HORACE WILLIS, of 10, Brighton Road, also in Southampton, Steward, do
hereby declare the nature of this invention to be as follows:-
-
This invention relates to improvements in anti-friction bearings for axles,
shafts, and the like, and in accordance therewith improved means are provided for
taking up or absorbing the friction consequent upon a high revolution of the axle
or shaft to which it is fitted while at the same time efficient lubrication is provided
for.
In carrying our invention into effect we provile a loosely fitting cap or liner of
any suitable anti-friction metal which is placed over the end of the axle or shaft
or in any central or supporting bearing block and lies between it and the bearing,
axle box, or thrust block. As the axle or shaft revolves so will also this loosely
fitting cap or liner be caused to revolve but of course at a lower speed and thus
friction in the bearings must naturally be reduced, minimising the risk of heated
bearings, and lessening wear and tear upon the brasses and other working parts.
Suitable slots or apertures and channels are provided or made in said loose
anti-fifiction caps or liners for the grease or other lubricant employed and
the tails ends and bearings surfaces of the shaft or axle fitting within the caps
or liners provided are preferably formed with longitudinal channels on their peri
pheries for the reception and collection of said grease or other lubricant, so that
when in motion the bearing surfaces may be evenly and properly lubricated.

Improvements in Anti-friction Bearings for Axles, Shafts, and the
like.
We, JOSEF CALCATERRA, of 35, Terminus Terrace, Southampton, Interpreter,
and HORACE WILLIS, of 10, Brighton Road, also in Southampton, Steward, 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 improvements in anti-friction bearings for axles,
shafts, and the like, and has for its object to provide means for taking up or

page_text: absorbing the friction consequent upon a high revolution of the axle or shaft
to which it is fitted, while at the same time efficient lubrication is provided
for, thereby reducing friction to a minimum and obviating the risk of the bearings
becoming overheated during the rapid revolution of the axle or shaft.
In carrying our invention into effect we provide a loosely fitting cap or liner
of gun-metal, bronze or any other suitable antifriction metal, which cap or liner
is placed over the end of the axle or shaft or in any central or supporting bearing
block and lies between it and the bearing, axle box or thrust block. As the
axle or shaft revolves so will also this loosely fitting cap or liner be caused to
revolve but of course at a lower (approximately half) speed and thus friction in
the bearings must naturally be reduced, minimising the risk of heated bearings,
and lessening wear and tear upon the brasses, and other working parts.
Suitable slots or apertures and channels are provided or made in said loose
anti-friction caps or liners for the grease or other lubricant employed, and the
tail ends and bearing surfaces of the shaft or axles fitting within the caps or
liners may if desirable be provided with longitudinal channels on their peri-
pheries for the reception and collection of said grease or other lubricant so that
when in motion the bearing surfaces may be evenly and properly lubricated.
For strengthening purposes we may provide the caps or liners aforesaid with
à skeleton lining of steel.
In order that our said invention may be the more readily understood and carried
into practical effect, reference is hereby made to the accompanying sheet of illus-
trative drawings, wherein:
Fig. 1 is a longitudinal section of an axle-box with our invention applied
thereto,
Fig. 2 a transverse section thereof through line A-B of Fig. 1.
Fig. 3 is an end elevational view of Fig. 1 looking in the direction of the arrow.
Fig. 4, is side elevational view of the anti-friction cap or liner, shewn inde-
pendently.
Fig. 5 is a similar view of the skeleton steel lining, while
Fig. 6 is an end elevational view of the cap or liner with the steel skeleton
lining in position therein.
In the drawings, wherein like letters of reference indicate corresponding parts
throughout the several figures, a represents the loosely fitting cap or liner having
the end lubricating channel a¹ leading from the oil or grease cup of the axle-
box b to the corresponding end of the axle c.
Lengthwise lubricating channels & are provided in the bearings, such lubrica-
ting channels leading from the oil or grease cup b¹ to within a short distance of
the opposite end of the axle-box b.
e represents the lubricating slots in the cap or liner a, such slots preferably
being arranged in the said cap or liner in a diagonal or oblique direction in
relation to the length of the cap or liner as shewn.
Where desirable or necessary we may provide the cap or liner a with a steel
skeleton lining f, for strengthening purposes, such skeleton lining having slots f
coinciding in position and dimensions with the lubricating slots e, in the cap or
liner a.
With our anti-friction cap or liner the bearings may conveniently be manu-
factured of steel instead of anti-friction metal as formerly, owing to the said
cap or liner taking up the greater part of the friction between the rotating axle or
shaft and the said bearings.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. The improvements in anti-friction bearings for axles, shafts and the like,
consisting in caps or liners formed of anti-friction metal, said caps or liners fitting
in the ends or other bearings parts of an axle, shaft or the like between same

page_text: and the bearings in such a manner that said caps or liners will have a slower
revolution than the axle, shafts or the like fitted therewith so as to take up the
friction between said axle, shaft or the like and the bearing, said caps having
lubricating openings therein, substantially as described and illustrated.
2. In anti-friction bearings for axles, shafts and the like, the caps or liners
fitting loosely on the ends of an axle or on the bearing parts of a shaft, hetween
same and the bearings, said caps or liners having steel strengthening linings
provided with peripherial lubricating slots, and lubricating slots formed in the
said caps or liners, said slots being disposed in an oblique manner in the said
caps or liners and coinciding with the lubricating openings in the steel-strengthen-
ing linings, a further lubricating opening being provided in the closed end of each
cap or liner, all arranged, constructed and operating, substantially as and for the
purpose described and as illustrated by the drawings.
