PROVISIONAL SPECIFICATION.
Improvements in or relating to the Bearings of Railway and
Tramway Vehicles and the like.
I, HARRY PENN, 40, Harold Road, Upper Norwood, London, S.E.. Engineer,
do hereby declare the nature of my said invention to be as follows:-
The object of my invention is to provide means for protecting the axle boxes
of railway and tramway vehicles and analogous bearings against the ingress
of dust grit and other matter having a deleterious effect on the bearings.
According to my invention I form the back of the axle box with a deep
recess extending nearly the whole width and height of the axle box, the recess
being open at the top. The axle passes at right angles to the recess through
the usual opening which in this case has to be formed in two plates between
which plates the recess is located. The recess carries a wooden or other shield
having an opening for the axle, which opening is provided with an annular
leather washer attached to the shield and rubbing in contact with the axle so
that it forms a dust tight joint. The shield is made so that it may readily
adapt itself to the position of the axle, the shield being capable of movement
in the recess.
The dust-tight joint may be made by means of the leather washer
above described or it can be effected by tubular or solid rubber encased in a
leather covering secured to the shield: the joint may also be rendered dust-tight
by other flexible materials and they may be arranged and (or) combined in the
manner best suited to the purpose or design of the box.

the usual opening, which, in this case, has to be formed in two plates, between
which plates the recess is located. The recess carries a wooden or other shield
having an opening for the axle, which opening is provided with an annular
leather washer attached to the shield and in rubbing contact with the axle, so
that it forms a dust tight joint. The shield is made so that it may easily
adapt itself to the position of the axle, the shield being capable of movement
in the recess.
The dust-tight joint may be made by means of the leather washer
above described, or it can be effected by tubular or solid rubber encased in a
leather covering and secured to the shield. The joint may also he rendered dust-tight
by other flexible materials, and they may be arranged and (or) combined in the
manner best suited to the purpose or design of the box.
And in order that my said invention may be particularly described and ascer
tained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.

is a portion of the axle, and the axle box. is a recess formed at the back
of the axle box between the plates e and f, the recess being open at the top and
plugged after the insertion of the shield, as shown at b. g is the shield formed
of wood or other suitable material, and made capable of adapting itself to the
position of the axle. is a leather washer secured, at or near its outer edge, to
the shield . its inner edge impinging against the axle a. as shown: a dust.
proof joint being thus secured. The sides g of the shield are straight, as shown,
or may be otherwise formed to prevent the shield turning with the axle.
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:
-
.
In hearings for the axles of railway and tramway vehicles and the like, the
combination with the axle box of a recess or space d; a shield y fitted in such
recess, and a washer of leather or other equivalent elastic material or materials
attached to the shield, substantially as and for the purposes described.
