PROVISIONAL SPECIFICATION.
Improvements in Axle Arms and Boxes for Road Vehicles.
We, GEORGE KELLNER, of 125, Avenue Malakoff, Paris, France, Coach
Builder, and HERBERT HALL MULLINER, of 300, Broad Street, in the City of
Birmingham, Carriage Builder, do hereby declare the nature of this invention to
be as follows
-
This invention consists of the herein described improvements in axle arms and
boxes for road vehicles. By this invention the axle box is rendered noiseless and
has an elastic lengthwise movement on the axle arm.
In carrying out this invention the axle box is of about the usual form outside
but at a certain distance in from the front end there is formed an internal
collar which is of about the same diameter inside as the outside of the reduced
front end of the axle arm. Between this collar (which is by preference made
with a flat face) and the nut on the end of the axle we provide a thick and wide
washer of cork or other suitable elastic substance and we also provide a similar
washer between a collar on the axle arm and an internal collar formed in the back
of the axle box which latter is recessed out to admit the said washer. The said
two washers arranged as above described prevent any noise and permit of a certain
elastic lengthwise movement of the axle box on the axle arm. The said nut which
is screwed on to the end of the axle arm and which keeps the axle box in place is
by preference made with a large wearing face against the washer and with a
square part for turning, this square part having four notches for a cotter pin or
being otherwise formed so as to allow of adjustment.

· Improvements in Axle Arms and Boxes for Road Vehicles.
We, GEORGE KELLNER, of 125, Avenue Malakoff, Paris, France, Coach
Builder, and HERBERT HALL MULLINER, of 300, Broad Street, in the City of
Birmingham, Carriage Builder, 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 consists of the herein described improvements in axle arms and
boxes for road vehicles. By this invention the axle box has an elastic lengthwise
movement on the axle arm and is prevented from making a noise when thus moving
lengthwise.
We will describe this invention by referring to the accompanying drawing on
which
Fig. 1 is a longitudinal section of an axle arm with its box constructed according
to this invention.
Fig. 2 is a front view of the end of the axle arm and nut thereon with the axle
box removed and
Fig. 3 illustrates a slightly modified form of the front end of the axle box.
The same letters of reference indicate the same or corresponding parts in all the
figures of the drawing.

page_text: In carrying out this invention the axle box A is of about the usual form
outside but at a certain distance in from the front end there is formed an internal
collar 6 which is of about the same diameter inside as is the outside of the reduced
front end c¹ of the axle arm C. This reduced part of the axle arm is continued
some little distance in the box beyond the collar b (see Fig. 1) so that the enlarged
part C of the axle arm will not come in contact with this collar b. Between this
collar 6 (which by preference is made with a flat face) and the nut D on the end c¹
of the axle C we provide a thick and wide washer E made of cork or of some
other suitable elastic substance and between the usual collar c² formed on the axle
arm and the usual internal collar g formed in the back of the axle box A there is
another cork or other suitable elastic washer F.
The two cork or other elastic washers E and F arranged as above described
permit of a certain elastic lengthwise movement of the axle box on the axle arm
but at the same time prevent any noise being caused by the said lengthwise
movement. The nut D above referred to which is screwed on to the end c of the
axle arm and which keeps the axle box in place on the arm is by preference made
as shewn with a large wearing face d' against the washer and with a square part d² for
turning. This square part has or may have four notches h h h h for the cotter
pin i so as to allow of adjustment of the distance between the face d' of the nut D
and the collar c² on the axle arm at the back end of the axle box; or instead of
the nut having four notches for the cotter pin as above described the nut may be
otherwise formed in any well known manner so as to allow of the said adjustment.
The screw thread is by preference turned out of the nut D at some distance up
from its face d' so as to allow of the face of the nut passing on to that part of the
axle arm c¹ which is not screw threaded and thus prevent the inside of the washer E
coming into contact with the screw threads on the end of the axle arm.
The collar in the axle box may either be formed in a piece therewith
(see Fig. 1) or be made as a separate collar and fitted therein as shewn in Fig. 2
and the wearing face of this collar and of the nut D which comes into contact
with the washer E and also the face of the collars g and c² which come into contact
with the washer F may either be flat as shewn upon our drawing or made slightly
bevelled or dished the faces of the said washers E and F being made of a
corresponding shape.
In conclusion we wish it to be understood that we are aware that one cork washer
such as F has been used in the back of the axle box prior to this invention and
we therefore make no exclusive claim to the use of the cork washer employed
in this way but
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The herein described improvements for preventing noise in axle arms and boxes
for road vehicles the said improvements consisting in making the axle box with an
internal collar at both ends in combination with two cork or other elastic washers
bearing respectively against said collars and against the collar on the back of the
axle arm and the face of the nut at the front of the axle arm the several parts
being constructed and combined together substantially as hereinbefore set forth and
illustrated by the accompanying drawing.
