PROVISIONAL SPECIFICATION.
Improvements in the Axle-bearings of Mine Trucks and similar
Vehicles.
We, GEORGE STOTT, Blacksmith, and JAMES WEEKS, Blacksmith, both residing
on the property of the Meyer and Charlton Gold Mining Company Limited, near
Johannesburg, in the South African Republic, do hereby declare the nature of
this invention to be as follows:-
This invention is designed with the object of so constructing the axle-bearings
of mine trucks and other like vehicles, as to render the part or parts subjected
to the most wear, readily detachable and renewable, and thus obviating the
necessity for the renewal of the whole bearing, when the part in contact with
or in which the axle rotates becomes worn.
In carrying out the invention the body or main part of the bearing is riveted,
bolted or otherwise suitably attached to the frame of the truck in the desired
position. This part is formed with a downwardly projecting piece provided with
a central and preferably tapered recess or cavity.
We provide a detachable and renewable piece or bush of a shape to partially
embrace, or, if desired, to wholly embrace that part of the axle contained within
the bearing. The detachable piece is formed with a shank or projection corres-
ponding in configuration and dimensions with the recess or cavity formed in
the main part, in which it fits. It will be evident that the projection or shank
may be formed of cylindrical, conical or other convenient shape and the down-
wardly projecting piece be recessed correspondingly. A hole is formed longi-
tudinally through this shank.
Holes are formed through the downwardly projecting part from the exterior
to the interior of the cavity on opposite sides, being so disposed as to coincidè
with the hole in the shank of the detachable piece when in position therein.
The detachable part is securely attached to the main part by means of a bolt
passing through the holes formed therethrough, and a band or strap is also secured
to the main part by the same bolt, encircling the axle on the under side and
acting to keep it in position or retain it within the bearing. When the detach-
able piece is constructed to wholly enclose that part of the axle contained within
the bearing the strap may if preferred be dispensed with.
When the detachable piece becomes worn it may very readily be removed and
replaced without renewing or even removing from the truck the body or main
part of the bearing.

We, GEORGE STOTT, residing on the property of the Meyer and Charlton Gold
Mining Company, Limited, near Johannesburg, in the South African Republic,
Blacksmith, and JAMES WEEKS, residing on the property of the New Comet Gold
Mining Company, Limited, near Boksburg, in the South African Republic,
formerly of the Meyer and Charlton Gold Mining Company, Limited, aforesaid,
Blacksmith, 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 is designed with the object of so constructing the axle-bearings
of mine trucks and other like vehicles, as to render the part or parts subjected
to the most wear, readily detachable and renewable, and thus obviating the
necessity for the renewal of the whole bearing, when the part in contact with
or in which the axle rotates becomes worn.
In order that our invention may be the more readily comprehended, we append
hereto an explanatory sheet of drawings marked with letters of reference corre-
sponding to the following description thereof.
Fig. 1 is a side elevation of an axle-bearing constructed in accordance with our
invention.
Fig. 2 a plan or view of same from below.
Fig. 3 an end elevation of the detachable and renewable part B detached, and
Fig. 4 a side elevation of Fig. 3.
A indicates the body or main part of the bearing, riveted, bolted or otherwise
suitably attached to the frame A¹ of the truck in the desired position, as seen
This part is formed with a downwardly projecting piece A³ provided with
at a.
a central and preferably tapered recess or cavity A
B is a detachable and renewable piece or bush of a shape to partially embrace,
or, if desired, to wholly embrace that part of the axle contained within the
bearing. The detachable piece B (see more particularly Figs. 3 and 4) is formed
with a shank or projection B corresponding in configuration and dimensions
with the recess or cavity A³ in which it fits. It will be evident that the pro-
jection or shank B₁ may be formed of cylindrical conical or other convenient
shape in lieu of that shown in the drawings and the piece A² be recessed corre-
spondingly. A hole 12 is formed longitudinally through the shank B'.
A are holes formed through the part A2 from the exterior to the interior of
the cavity A on opposite sides, being so disposed as to coincide with the hole Ba
in the shank B when in position therein.
D is a bolt passing through the hole B and through the holes A for securely
attaching the detachable part B to the main part A.
C is a band or strap, secured to the main part A by the bolt D, encircling the
axle on the under side and acting to keep it in position or retain it within the
bearing. When the detachable piece B is constructed to wholly enclose that
part of the axle contained within the bearing strap C may, if preferred, be
dispensed with.
When the piece B becomes worn it may very readily be removed and replaced
without renewing or even removing from the truck the body or main part A of
the bearing.

page_text: Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
1. In an axle-bearing for mine trucks, the combination of a main part and a
detachable piece or bush in which the axle revolves formed with a shank or
projection fitting a correspondingly shaped cavity or recess provided in the
main part in which it is secured, substantially as described.
2. An axle-bearing for mine trucks and similar vehicles comprising a main
part, as A, formed with a downwardly projecting portion, as A, provided with a
recess or cavity, as A³, a renewable piece, as B, formed with a shank or projection,
as B', corresponding to the cavity A3 in which it fits, a bolt, as 1), passing
through a hole, as B, and holes, as A', formed in the shank B and part A,
respectively, for firmly securing these parts together, and a strap, as C, also
secured to the main part A by the bolt D for retaining the axle within the
bearing, substantially as described and shewn in the accompanying drawing.
