AN IMPROVED FEED-LUBRICATOR
Year: 1885

page_text: I, HERBERT JOHN ALLISON, of the firm of Allison Brothers, of 52 Chancery Lane;
London, in the County of Middlesex, Patent Agents, do hereby declare. the nature
of my invention for "AN IMPROVED FEED-LUBRICATOR" to be as follows:-

,
This Invention consists in a rod passing loosely down the neck of a cup con-
taining grease for lubricating and which communicates with the journal-bearing
to be lubricated. The lower end of the rod rests on the shaft revolving in the
journal-bearing and the upper part of the rod which is contained within the cup is
provided with a set of arms projecting therefrom. The heat-caused by the friction
of the rod upon the revolving shaft melts the grease which passes down the neck
of the cup into the journal-bearing.

page_text: I, HERBERT JOHN ALLISON, of the firm of Allison. Brothers, Patent Agents, of
52 Chancery Lane, London, in the County of Middlesex, do hereby declare the
nature of my invention for "AN IMPROVED FEED-LUBRICATOR," which invention
has been communicated to me from abroad by John Scott Hall of the City of New
York in the County and State of New York, United States of America, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
In the drawings, figure 1 is a vertical central sectional view of a feed lubricator
containing my invention, and showing the journal and. bearing to which the same
is attached; and figure 2 is a perspective side view in detail of the device
embodying my improvement in its preferable form.
My invention consists in a feed-lubricator composed of a cup or reservoir for
containing the grease or lubricant, and a channel or communication leading there-
from to the bearing to be lubricated, together with a stem or needle extending
longitudinally, of said channel from the journal upon which its lower or outward
extremity impinges to and into the cup or reservoir where its upper or inward
extremity is provided with radial arms or projections within the cup, as herein-
after described, and for the purpose hereinafter set forth.
:
A is the cup or reservoir, in which is placed the lubricant-grease. This cup
has the usual cap or cover a. A channel or communication a', extends from the
cup to the journal B, in the bearing, the usual box being shown in dotted lines in
figure 1, with the lubricator attached to the bearing in, the ordinary way by
screwing it into a channeled seat in the cap of the box.
A stem or needle C, extends longitudinally of the channel a¹, and is of such a.
diameter that it will move easily in said channel, and will leave a space about it
between its face and the wall of the chanupl, as shown in figure The passage of
the lubricant from the cup along said channel to the journal is thus provided for.
The outward or lower extremity of the stem C, projects to and impinges upon the
journal as shown. The upper or inward end of the stem, within the cup, is
provided with radial arms or projections of a greater or less length, and of any
desired form or dimensions. I find it preferable to construct the stem and arms in
the form shown in figure 2, namely, to continue to extend the stem upward of the
cup to near its rim-line, and to have the radial arms in the form of branches c,
carried by a sleeve c³, which fits snugly on the stem, and yet is capable of adjust-
ment longitudinally thereon. This may be economically effected by taking a piece
of metal tubing of suitable length, and which will fit upon the stem as described,
and cutting the said tube lengthwise from its top to near its bottom, and then
spreading out the split portions radially, as shown.
I also find it preferable to give to the radial arms such direction and form that
they will extend nearly to the interior face of the cup and will conform to the
outline thereof, as shown in figure 1.
Any desired number of these arms or branches may be employed and they may
be formed of separate pieces attached to the stem or may be in one and the same
piece as the stem, and also may be in the form of irregular projections on the stem
extending across the cup in any direction.

page_text: The object of my invention is to facilitate the melting and rendering sufficiently
fluid the lubricant employed to enable its constant flow to the journal to be
secured. As the lubricants generally employed in oilers of this description are
placed in the cup in a more or less solid, or semi-solid state, the rendering of them
fluid so that they will pass readily and in a constant even flow to the journal is
important.
. °
In the operation of my invention the heat generated by the journal in its
revolutions in the bearing is transmitted along the stem C, and thence to and along
the branches or projections c, and so is communicated to the lubricant in the cup,
and consequently liquefies it so that it will run easily and constantly through the
channel a, around the stem to the journal. Furthermore, the vibrations of the
journal will cause the stem in contact with it to vibrate, and this produces a
tendency in the stem to rotate, thus causing the branches or projections thereof to
be carried around and through the melting lubricant in the cup, agitating the same
and assisting in producing the desired constant and effective flow of the lubricant
to the journal.
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:
1. In a feed-lubricator, the combination, with the cup or reservoir for holding
the lubricant and the channel for conducting the same to the journal-bearing, of a
needle or stem extending loosely longitudinally of said channel, and with its
outward extremity adapted to impinge upon said journal, and provided. with arms
or projections extended transversely of the said cup within the same, as and for the
purpose set forth.
•
2. In a feed-lubricator, the combination with the cup or reservoir for holding
the lubricant and the channel for conducting the same to the journal-bearing, of a
needle or stem extending loosely longitudinally of said channel, and with its
outward extremity adapted to impinge upon said journal, and provided with arms
extending radially and in conformity with the outline of the interior of the said
cup from a sleeve fitted on said needle or stem within the said cup, as and for the
purpose set forth.
