PROVISIONAL SPECIFICATION.
Improvements in or connected with Shields of Axle Boxes.
I WILLIAM HUTTON of 12 Montague Place, Russell Square, in the County of
London, Gentleman, do hereby declare the nature of this invention which has been
communicated to me from abroad by Matthew Brown of Albyn Villa, Plein Street,
Woodstock near Cape Town, Cape of Good Hope Coach Builder, to be as
follows:-
This invention relates to packing the shields employed in axle boxes to prevent
entry of dust and escape of oil or other lubricant, also to fit side caps with loose
curved or wavy shaped springs in side recesses of the shields to make the shields
come and go from the oscillations of the vehicle without rattling and maintain the
shields in their proper positions either as single shields or as double ones.
For the purpose of this invention one or both faces of the shield next the axle
hole is grooved and a gasket of lambskin or sheepskin with the wool on, or worsted,
asbestos, packing, linen or such like material is fixed therein with a projecting
fringe to bear against the circumference of the axle to lead escaping oil or liquid
grease into the oil well and to prevent it passing to the outer side.
The edge of the shield is also similarly treated and packed the end being
provided with a leather, asbestos or other facing as a packing to exclude dust.
The sides of the shields are recessed and rectangular shaped casings are fitted in
them, the casings having springs held within the return edges of them to retain the
springs in their positions and yet give play for compression.
The open portions of the casings fit in the recesses of the shields and the outer part
bear against the walls of the axle box and where two adjoining shields are used one
casing on each side edge will serve for both if desired.

Improvements in or connected with Shields of Axle Boxes.
I WILLIAM HUTTON of 12 Montague Place, Russell Square, in the County of
London, Gentleman do hereby declare the nature of this invention which has been
communicated to me from abroad by Matthew Brown of Albyn Villa, Plein Street,
Woodstock, near Cape Town, Cape of Good Hope, Coach Builder, 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 packing the shields employed in axle boxes to prevent
entry of dust and escape of oil or other lubricant also to fit side caps with loose
curved or wavy shaped springs in side recesses of the shields to allow the shields to
come and go from the oscillations of the vehicle without rattling, and maintain the
shields in their proper positions either as single shields or as double ones.
For the purpose of this invention one or both faces of the shield A next the axle
hole is grooved and a gasket B of lamb skin, sheeps skin, with the wool on or
worsted, asbestos packing, linen or such like material is fixed therein with a
projecting fringe to bear against the circumference of the axle C to lead escaping
oil or liquid grease into the oil well D and to prevent it passing to the outer side.

page_text: The edge of the shield A is also similarly treated and packed as at E the bottom
end of the shield A being provided with a leather, asbestos, or other facing F as a
packing to exclude dust.
Referring to the annexed drawings illustrating the invention
Figure 1, is a sectional plan of an axle box fitted with shield.
Figure 2, is a side sectional elevation of same.
Figure 3, is an inside face view of the shield showing the packing.
Figure 4 is an outside face view showing the recesses for the reception of the
-springs.
Figure 5 is an end or edge view showing in section the rectangular box in which
the spring may be enclosed.
The sides of the shield A are recessed as at G and rectangular shaped casings H
may be fitted in them the casings having springs I held within the return edges of
them to retain the springs in their positions and yet give play for compression.
These springs I, which may be used with or without the rectangular casings
press against the side caps J, J, and against the recesses G to force or maintain
the shield A always in close contact with the face K of the axle box L at the same
time allowing for lateral oscillations of the axle C such as when rounding curves.
For maintaining the shield in its proper vertical position the springs I press into
small recesses M in the shield A or they may be made of the 'same length as the
.recesses G as shown in Figure 5.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
-claim is :-
1. The improvements in or connected with shields of axle "boxes herein before
described and substantially as shown in the annexed drawings.
2. Providing the edge of axle box shields next the axle also their outer edges
with a packing of lambskin, sheepskin with the wool on, worsted, asbestos packing,
linen or such like material in the manner and for the purpose described and sub-
stantially as shown in Figures 3 and 4 of the annexed drawings.
3. Fitting curved, wavy or other springs with or without rectangular casings
between the side caps and. recesses in the shields of axle boxes for exerting a face
pressure in order to maintain the shield in its proper position and prevent rattling
.as described and arranged substantially as shown in the drawings.
