COMPLETE SPECIFICATION.
Improvements in and relating to Wheels for Carriages, Ploughs, and
the like.
I, AUGUST REIMANN, of 41 Blumenthalstrasse, Friedrichsberg, Berlin, in the
Empire of Germany, Locksmith, 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 wheels for carriages ploughs and the like, more
particularly to the construction of the naves or hubs thereof, and has for its object
to render lubrication easier and more effective with less consumption of lubricating
material, and to prevent the access of dirt.
In the accompanying drawing: -
Figure is an elevation of the improved wheel nave or hub as seen from the
rear.
-x of Figure 2, while
Figure 2 represents a longitudinal section of the same.
Figure 3 is a cross section taken on the line
Figure illustrates a modified construction.
On the axis a is arranged a collar a 1 which serves for fixing the nave or hub b.
The head a 2 of the axle is conical or may be cylindrical, and is surrounded by the
wheel box c. This wheel box is inserted in the customary manner into the wheel
nave or bub b, but may also be made in one piece therewith. The spokes e which
carry the wheel-rim are shown broken off. On the inside is arranged the disc f
which is connected with the nave or hub 6 by means of the screws f1, in such a
manner that the collar al will be situated between the nave or hub b and the
disc f. In this manner the wheel is fixed upon the axle.
In lieu of the nave or hub and wheel box shown in Figure 2 which is specially
adapted for ploughs, use may also be made of differently constructed naves or hubs
and boxes, for instance the box represented in Figure 4 which is open in front and
covered by a cap d screwed into the same. For obtaining a tight joint a packing
ring n may be inserted. The essentially new feature consists in the device
hereinafter described.
For facilitating the introduction and distribution of the lubricating material a
slot g is provided in the wheel box, which slot may be covered by a tight fitting
slide adapted to be moved in a guide as shown. This slide may be slid
lengthwise or transversely over the same and is suitably fixed by means of a
clamping screw h 1.
In lieu of the slot 9 use may also be made of a series of holes g1, 91, g 1,.
(Figure 4) one or more lubricating grooves i being provided in that case on the
inside of the box.
:
Through this slot g or these holes g1 the lubricating material may be easily
introduced and spread over the whole length of the journal, so that even in the case.
of very long boxes an ample and rapid lubrication is obtained.
In order that the lubricating material may not be thrown out inwards a protecting
ring K is provided on the inside of the nave or hub tightly around the collar a 1;
this ring being provided with a disc of india-rubber or the like, so that an annular
closed receptacle is produced. The lubricating material passing out from the box
inwards is kept back, by this arrangement and keeps the collar al well lubricated
while the packing disc moreover effectually prevents the access of dirt to the
interior of the box.

page_text: 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. In wheels for carriages, ploughs and the like a nave or hub provided with
one or more openings g or 91 in the wheel box c which are adapted to be closed
by a slide h or otherwise, for the purpose of introducing the lubricating material so
that the whole bearing surfaces may be effectually lubricated.
2. In wheels for carriages, ploughs and the like a nave or hub having a protecting
ring K arranged integrally thereon and a rubber disc or the like, which ring
prevents the lubricating material which has passed inwards from the wheel box
from being thrown out and which keeps the collar a 1 serving to fix the wheel on
the axle well lubricated.
Dated this 20th day of December 1895.
