Improvements connected with Contractors', Colliery, and other
similar Railway Wagons.
J. HERMANN SICHELSCHMIDT of 10 Königswall, Dortmund, in the German
Empire, Manufacturer, 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 the wheels bearings and underframing of contractors'
colliery and other similar railway wagons and its objects are to provide means for
the automatic adjustment of the bearings in work, to enable the underframe to be
mounted in a simple and easy manner, to ensure the constant supply of clean
lubricant, and to enable the wheels to be constructed cheaply.
I will describe my said invention with reference to the accompanying drawings
in each of the figures of which similar parts are denoted by similar letters of
reference.
Figure 1 is an elevation, partly in section, of the two wheels of one side of a
wagon, viewed from between the rails.
Figure 2 is an end elevation of one of the wheels, of part of the axle, and a
vertical section of the axle-box and bearing.
Figure 3 is a plan, partly in section, of Figure 1.
Figure 4 shews three views of the bearing, in front and side elevation, and in plan
respectively.
The main part of the frame A, is cast in one piece, with the axle boxes G G
and with the cavity E, to contain the lubricant. The axle boxes, as shewn by
Figures 1 and 2, consist of hollow vertical cylinders open at the top and closed at
the bottom by a hemisphere of the same strength as the cylindrical part. On cach
side of the axle box there is an open tubular part C, for the passage of the axle,
and having such an internal diameter as to allow a little play for the axle
horizontally and vertically.
The brass or bearing D, for each wheel, is contained within the upper cylindrical
part of the axle-box, is cylindrical in horizontal cross section, and is provided at
the top with a central circular recess H.
The lubricant chamber E, communicates by a comparatively broad channel N,
with the bearings D, in each of which there is an oil hole communicating with the
recess H, with which there also communicates, through the side of the bearing, a
continuation of the chanuel N, as shewn by Figure 1. A strong lubricating wick
is laid in the channel N, from the chamber E to each of the two recesses H, in the
bearings D, and conducts the lubricant from the chamber to the working faces of
the journal and bearing.
The upper plate B, of the framing, has on its inner side, two cylindrical pro-
jections F, which fit respectively within the recesses H in the upper faces of the
brasses D.
The frame A having been arranged in place, and the brasses placed above the
axles, the top plate is placed above it and the two are then firmly screwed or
fastened together. The engagement of the cylindrical parts F, with the recesses H,
in the brasses, permits to the latter sufficient rotary motion around a vertical axis,
but the distance of the plates apart being fixed by the body of the wagon to
which they are secured, no longitudinal motion of the bearings-on the axles can
occur.
The wheel R, with the exception of the cap K, is pressed from a single piece
of iron or steel, and the cap K is afterwards welded on by electricity or other-
wise. If an attempt were inade to press the cap at the same time with the

page_text: body and flange of the wheel, the metal would generally be found to crack or become
unsound.
Numerous tests with these wheels have shewn that they possess greater stability
and are particularly suitable for the work which they have to perform. It will
be observed from the section Figure 3, that the whole substance of the wheel
is of the same thickness, it being pressed out of a heated blank of plate iron
or steel.
The wheels may be secured upon their axles by split pins S, or by other suitable
means.
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. Axle boxes and bearings for the wheels of contractors' and colliery and
similar wagons, constructed and arranged substantially as hereinbefore described
and as illustrated by the accompanying drawings.
2. In combination with the axle box and bearing of a contractors' colliery and
similar wagon, a lubricant chamber, and a wick channel and wick connecting the
chamber with the oil hole of the bearing, constructed and arranged substantially as
herein before described and as illustrated by the accompanying drawings.
3. In contractors' colliery and similar wagons, wheels pressed out of a single
plate, and having a cap welded or otherwise secured thereon, substantially as
hereinbefore described and as illustrated by the accompanying drawings.
Dated this 26th day of October A.D. 1892.
