PROVISIONAL SPECIFICATION.
Improvements in and in the Manufacture of Axle-boxes.
I, HERMANN SICHELSCHMIDT of Bochum, Dortmund, in the Empire of
Germany, Engineer and Factory Director, do hereby declare the nature of this
invention to be as follows :—
This invention relates to axle-boxes such as are used for outside axle journals
and my invention consists primarily of constructing the upper and lower parts of
the case or enclosing wall of such boxes formed out of a single piece of sheet steel
while the front side or end of such axle-box is rendered movable by being mounted
on a hinge or equivalent joint upon which it is capable of being turned to afford
access to the interior of the axle-box or bearing while means are provided for
firmly closing said hinged front part through which also is an opening for the
purpose of lubrication.
The case or main enclosing wall is formed in any suitable manner (for instance
by pressing same) out of a sheet of steel of suitable quality and thickness into the
desired shape the two ends being brought together at the top and bolted or other-
wise strongly secured together such bolts or fastenings advantageously passing
through the upper part of the bearing or block which carries the weight of the
car or vehicle transmitted thereto through the axle-this bearing block being thus
mounted and kept in position by the same bolts or fastenings which secure the two
ends of the case firmly together at the top.
On top of this case at the middle thereof there is rivetted or otherwise suitably
mounted a sheet metal plate which at its front end is bent round a hinge pin
this plate being of a less width than the said hinge pin and of a length extending to
the back of the box or thereabouts to which it is firmly attached in any suitable
manner.
Suitable eyes or lugs are mounted on the movable front cover or lid of the axle
box and are adapted to engage with the said projecting ends of the said pin in such
a manner that the cover is suspended so as to be free to turn un said pin and this
said cover is hinged to the axle box or in any other equivalent or suitable manner.
This lid or cover terminates at its lower end in a lug or other suitable manner
and can be fastened at its lower end by any suitable means such as a bolt and nut
screwed thereon.
Inside the box i.e. inside the said hinged cover there is provided a suitable frame
for the reception of a dust-excluding ring or washer or other suitable means for
the purpose of preventing dirt that might enter through the joint (where the cover
meets the case) from penetrating to the axle journal or bearings.
Besides the aforesaid door or opening in the front cover for lubricating also a
lubricating passage (or passages) is arranged through the aforesaid block or bearing
with a suitable lid or cap or other means for closing said passage in the top of the
axle-box.
Any suitable means may be provided for mounting or fastening this axle-box in
position as desired.

I, HERMANN SICHELSCHMIDT of Bochum, Dortmund, in the Empire of
Germany, Engineer and Factory Director, 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-axle-boxes-such as are used for outside axle journals.
and my invention consists primarily of constructing the parts forming the case or
enclosing wall of such boxes out of a single piece of sheet steel while the front
side or end of such axle-box is rendered movable by being mounted on a hinge or
equivalent joint upon which it is capable of being turned to afford access to the
interior of the axle-box or hearing while means are provided for firmly closing
said hinged front part through which also is an opening for the purpose of
lubrication.
The case or main enclosing wall is formed in any suitable manner (for instance
by pressing same) out of a sheet of steel of suitable quality and thickness into the
desired shape the ends being brought together at the top and bottom and bolted
or otherwise strongly secured together such bolts or fastenings at the top
advantageously passing through the upper part of the bearing or bluck which
carries the weight of the car or vehicle transmitted thereto through the axle-
this bearing block being thus mounted and kept in position by the same bolts or
fastenings which secure the two ends of the case firmly together at the top.
On top of this case at the middle thereof there is rivetted or otherwise
suitably mounted a sheet metal plate which at its front end is bent round a hinge
pin this plate being of a less width than the length of the said hinge pin and of
a length extending to the back of the box or thereabouts to which it is firmly
attached in any suitable manner.
Suitable eyes or lugs are mounted on the movable front cover or lid of the axle
box and are adapted to engage with the said projecting ends of the said pin
in such a manner that the cover is suspended so as to be free to turn on said pin
and thus said cover is hinged to the axle box or in any other equivalent or
suitable manner.
This lid or cover terminates at its lower end in a lug or other suitable manner
and can be fastened at its lower end by any suitable means such as a bolt and nut
screwed thereon.
Inside the box i.e. inside the said hinged cover there is or may be provided a
suitable frame for the reception of a dust-excluding ring or washer or other suitable
means for the purpose of preventing dirt that might enter through the joint (where
the cover meets the case) from penetrating to the axle journal or bearings.
Besides the aforesaid door or opening in the front cover for lubricating also a
lubricating passage (or passages) is arranged through the aforesaid block or bearing
with a suitable lid or cap or other means for closing said passage in the top of the
axle-box.
Any suitable means may be provided for mounting or fastening this axle-box in
position as desired.
And in order that my present invention may be easily understood and readily
carried into practice I will proceed to describe same with reference to the drawings
hereunto annexed.
Fig. 1 is a vertical longitudinal section through the box or bearing, and
Fig. 2 is a view partly in front elevation and partly in cross-section.
The case or enclosing wall A consists of two parts A' A' which are respectively
formed from a single piece of sheet steel by being stamped up or pressed out of

page_text: same into the desired shape the bottom lips or edges overlapping as shown in
Fig. 2 and firmly rivetted together as shown in Fig. 1 while at or near the top
they are secured (with the bearing block thereinbetween) by the rivetted bolts i
as bereinafter explained.
To the middle of the upper front edge of the axle box A thus formed from
sheet steel there is rivetted or welded a piece of sheet metal which is bent round
a pin a or adapted to hold said pin.
The piece b is somewhat shorter than the pin a so that the latter projects beyond
both sides of the piece b.
Eyes or lugs are mounted on the front cover or lid d of the axle box and
engage with (ie. hinge on) the said projecting ends of the pin a in such a manner
that the cover it is hinged on the pin a.
The cover d terminates at its lower end in a lug e and can be fastened at that
place by any suitable means such as a nut on the screw f
Behind the cover d in the box in front of the end or head of the axle journal
there is provided a frame g for the reception of a dust-excluding disc ring or
washer for the purpose of preventing any dirt that might enter through the joints
of the cover d from penetrating to the axle journal.
The weight of the car or vehicle is transmitted to the axle through the
intermediary of the bearing-piece h which is fitted into the axle box and is kept in
place by means of strong transverse bolts such as i passing through same and
through the side walls A1 and A2 and rivetted so as to firmly secure all these
parts together.
k
This bearing block h is provided with a lubricating passage by which the axle
can be lubricated from above-access to this passage k being obtained by means of
a second lubricating opening closed by a cover such as l.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Constructing the case or enclosing wall of axle boxes out of sheet steel
substantially in the manner and for the purposes hereinbefore set forth.
2. An axle box for the purposes stated-in which the case or enclosing wall is
formed out of sheet steel and having in combination therewith a cover hinged
thereto serving as front end of the box substantially in the manner hereinbefore
set forth.
3. The improved construction of axle boxes substantially in the manner and for
the purposes herein before set forth.
4. The improved construction of axle boxes substantially in the manner and for
the purposes herein before described and illustrated in the drawings hereunto
annexed.
