IMPROVEMENTS IN LUBRICATORS
Year: 1885

page_text: I, ROBERT LAUDER of 76 Seedley Grove, Pendleton, in the County of Lancaster,
Engineer, do hereby declare the nature of my invention for IMPROVEMENTS IN
LUBRICATORS, to be as follows:-
My invention relates to certain improvements in apparatus for lubricating
bearings of shafting; and has for its object the arrangement of the apparatus in
such a manner, that a constant supply of oil is transmitted to the shafting bearings
which is regulated according to the speed at which the shafts revolve, this
I accomplish in the following manner.
I form a light casing or reservoir of tin or other metal plate, made to enclose the
whole or a portion of the shaft bearing which is of the ordinary construction. In
this casing I pour a quantity of oil proportionate to the size of the bearing to be
lubricated, and mount upon the revolving shaft a narrow disc which rotates in the
oil and thereby raises a certain quantity which is removed from the circumference
of the disc by a scraper, which conveys it into a pipe channel extending over the
centre of the bearing, through which channel the oil runs on to the bearing,
thereby constantly lubricating the same; the oil from the bearing running back
into the casing to be again raised by the disc.

page_text: I, ROBERT LAUDER, of 76 Seedley Grove, Pendleton, in the County of Lancaster,
Engineer, 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:—
My invention relates to certain improvements in the apparatus for lubricating
bearings, and has for its object the arrangement of the apparatus in such a manner,
that a constant supply of oil is transmitted to the shaft bearings, which is regulated
according to the speed at which the shafts revolve.
My invention consists in attaching around the plummer block or hanger, a light
casing or reservoir which is partly filled with oil, in which rotates a metal disc
mounted on the shaft; and as the latter revolves, a certain quantity of oil adheres
to the disc, which is removed by means of a metal scraper into a trough, from
which it runs by gravity through a pipe into the centre of the bearing, and after
lubricating the bearing, is conveyed back to the reservoir to be used again; thus
by these means, it is constantly circulating through the bearing and retained in
the reservoir.
In order that my invention may be better understood, reference is made to the
accompanying drawings, in which Fig. 1 represents an end elevation of an ordinary
plummer block with my improved lubricator attached; and Figs. 2 and 3 represent
respectively a section and plan of the same.
To the end of the plummer block A, I attach a light circular casing or
reservoir B, made preferably of tin; which is partly filled with oil, the amount
depending upon the size of the bearing to be lubricated; and in the reservoir B
there rotates a metal disc C, clamped to the shaft D. When the shaft and disc
rotate, the oil adheres to the disc Č, and is removed from its circumference by the
scraper E into the trough F, from which it runs by gravity through the pipe G to
the centre of the plummer block A, and visably drops on to the bearing through
the hole H. After lubricating the bearing, the oil runs back into the reservoir B,
from the end adjacent to the same; but at the opposite end of the bearing, it runs
into the casing J fixed for that purpose, from which the oil is conveyed by the
pipe K, to the reservoir B to be used again.
The scraper E is hinged at L a little beyond the highest point of the circum-
ference of the disc 0; but there are other positions where the scraper may be fixed
which would serve the purpose equally as well without departing from the
characteristic nature of the invention; and at the end where it comes in contact
with the disc, it is flanged at one side and inclined towards the trough F, so that
the oil can readily run into the same.
In order that the supply of oil to the bearing may be regulated, and also to
prevent wear, the scraper E is capable of adjustment; this I accomplish by
hanging the latter to the casing B at L. and about its centre I fix the screwed
spindle M, which passes through the casing B, and on which is placed the thumb
screw N, the underside of which bears against the casing B made level in that
place. By turning the thumb screw N, the spindle M rises or descends whereby
the scraper E is raised or lowered.

page_text: It will readily be seen from the foregoing, that the quicker the shaft D rotates,
the more oil does the disc C take up, thus the demand creates the supply.
The foregoing description applies to plummer blocks, but my invention is also
applicable to hangers, and when applied to them, I make the bottom portion of the
casing or reservoir to enclose the bottom portion of the hanger; thereby dispensing
with the pipe K for conveying the oil back to the disc from the opposite side of
the journal to which the disc is placed.
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
I claim is
The combination of the reservoir B having therein a rotary disc O with the
adjustable scraper E, all arranged substantially in the manner and for the purpose
described.
