Improvements in Lubricators for Axle Bearings.
I, NICOLAUS BICK, Certificated Foreman Machinist, of Elversberg, in the Empire
of Germany, 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:--
Notwithstanding various experiments to produce a satisfactory lubricating
arrangement for the axles of waggons, trucks and the like, success has not yet
been attained, the contrivances introduced hitherto having the disadvantages that
they either only imperfectly apply the lubricating liquid to the axle, or that the
liquid not only runs away when the vehicle encounters a shock, but also during the
ordinary running of the vehicle, so that there is a great waste of oil. The present
invention is intended to obviate the disadvantage referred to.
In the accompanying drawing:
Fig. 1 is a longitudinal section of lubricating apparatus constructed according
to this invention.
Fig. 2 is a cross section of the same.
Fig. 3 an inverted plan, and
Figs. 4 and 5 show the lubricating ring in end elevation and sectional elevation
respectively.
As will be seen from the drawing, the new lubricating apparatus consists of an
annular oil receptacle closed on all sides. In this receptacle a slot is formed,
through which the oil is conveyed from the receptacle to the axle by means of a
lubricating ring. For this purpose, on each of the widened ends of the axle-box k
an inner box his arranged, which is furnished with a boring that corresponds with
the axle a; and forms an annular oil receptacle. In the upper middle part of
this box is a slot f, in which the lubricating ring r is inserted. The slot f is only
of a sufficient length to allow the ring to rotate with the axle, and in this manner,
a large closed space is secured for the reception of the lubricating liquid. As
soon as the vehicle begins to move, the ring rotates with the axle and in so rotat-
ing, continuously conveys oil thereon. However worn away the axle may be in
the inner box, in consequence of the wear and tear, the oil cannot flow out. The
oil which has been used collects in the space between the axle and the box k. If
the vehicle be emptied by tilting, the liquid can again reach the lubricating
positions, but if the vehicle be turned over on to the side and the axle of such a set
of wheels comes into a vertical position, a flowing out of the lubricating material
is equally impossible, as it collects in the space between the two walls. In order
that the lubricating ring r may be introduced into the axle box through the open-
ing n, it must consist of two parts and may be in the form illustrated in Fig. 4-5.
The opening at n is closed by means of an india-rubber ring, after the lubricating
ring has been inserted. In consequence of the set of wheels being screwed with
this part of the axle box to the bottom of the waggon, a tighter closing is effected
at n. In order that the ring r may not be jerked out of the slot, supports and i
are provided. Owing to the use of the lubricating ring in conjunction with the

page_text: double walled lubricating box, all loss of material is avoided and nevertheless, the
lubricating of the axle effectually assured.
Instead of the lubricating ring, a lubricating chain can, as a matter of course,
be employed with equal advantage.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
1 claim is
A lubricating apparatus with annular oil-receptacle in the form of an axle-bear-
ing for waggons, trucks and the like, the distinguishing feature being a slot-shaped
incision in the upper part of the inner wall of the oil receptacle that exposes
the axle on which bears a lubricating ring r divided into two parts, inserted in
place by means of an opening n, which can be closed, and guided between arms or
supports i, for the purpose of securing effectual and economical lubrication.
