COMPLETE SPECIFICATION.
Improvements in Bearings, and in Means for Lubricating the same.
I, Dr. PAUL PONDORF, Partner of A. Kolbe & Co., of Gössnitz in the
Dukedom of Saxe-Altenburg in the German Empire, Manufacturer, do hereby
declare the nature of my invention and in what manner the same is performed to
be particularly described and ascertained in and by the following statement:-
The present invention consists of a self lubricating bearing comprising the
details of construction hereinafter described and particularly pointed out in the
claims.
And in order to render the present specification more easily intelligible reference
is had to the accompanying drawing in which similar letters of reference denote
similar parts throughout the several views:
Fig. 1 being a side elevation of a bearing for overhead shafting provided with
the present self lubricating device,
Fig. 2 an end elevation of Figure 1,
Fig. 3 vertical section through the middle of Figure 1,
Fig. 4 end elevation of a similar bearing having no extra bush under the shaft
and
Fig. 5 a vertical section through the bearing of Figure 4.
The standard is secured to the ceiling of the workshop in the usual manner
and carries in its downwardly extending arm the lower bush a of the bearing
said bush being provided with the cap b secured thereon at one side by the
screw and at the other by an upwardly extending arm & having an inclined
surface at its upper end between which and a lug i on the standard, also provided
with an inclined surface, a wedge g is driven, which secures the cap b in position.
Below the bush a which carries the shaft a set screw f¹ is arranged by means of
which the said bush may be adjusted in position. The lubricating device consists
of the upright tube c* carrying at its upper end the bowl d for the lubricating oil
or other means and having at its lower end a horizontal arm opening into a
horizontal channel c, extending across the bush a. This channel is provided with
an upwardly extending slot e running its whole length and establishing communica-
tion from the channel c to the shaft.
The upper edges c² of the slot are sharp and tend to scrape the superfluous oil
off the shaft as the latter revolves. The operation of the device is very simple.
The oil passes by gravity down the tube c* into the channel c and reaches the
shaft through the slot calong nearly the whole length of the bearing, which it
lubricates, the supperfluous lubricating material being scraped off the shaft by
means of the sharp corners o' of the channel.
In Figures 4 and 5 exactly the same arrangement is shown with the distinction,
that the bearing in this case is not provided with a removeable lower bush a but
formed in the standard i.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is performed I declare that what I
claim is :-
In a bearing the combination of a channel extending through one side of and
almost entirely through the bearing in a direction parallel to and underneath the

page_text: shaft, a reservoir for the lubricating material and pipe connecting to said channel,
a slot extending the whole length of said channel and establishing communication
between it and the shaft and sharp longitudinal upper edges to the said slot
substantially as described and for the purpose specified.
