I JAMES YATE JOHNSON of 47 Lincoln's Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of this Invention which has been communicated
to me from abroad by Dickson D. Mac Mullen of the City of Brooklyn County of Kings
and State of New York in the United States of America, Gentleman and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
The object of the Invention is to provide a lubricator for journals and large bearings
more convenient, inexpensive and less wasteful than those hitherto provided and the
invention consists in making a lubricator box of two parts adapted to be readily
placed in and removed from the journal box the said box being provided with a tube or
opening holding a wick or capillary conductor which hears againsi. the axle to be
lubricated, supplying oil thereto from the box by capillary attraction.
I will describe the Invention more particularly with reference to the accompanying
drawing.
Figure 1 shows the bottom part of the lubricator box.
Figure 2 shows the lubricator box with the top portion attached and one side
partially cut away.
Figure 3 shows the improved lubricator box placed in position in a journal box, and
Figure is a cross section of a portion of the same the section being taken on the
line - Figure 3.
The lubricator box consists of two parts namely the cover A and the reservoir for
holding the oil or lubricating material B. The upper surface of the cover A is formed
to fit closely to the axle it having a curved or concave surface a and it is provided
with a wick opening or wick holder C. Upon one side of the top of the cover A is
placed the oil inlet E with its cover e and spring e¹ the said spring being so arranged
as to hold the cover tightly down, closing the inlet when the said cover is shut and
also holding it rigidly open when the cover is raised.
The placing of the oil inlet to one side makes it possible to fill the reservoir without
removing the latter.

page_text: The lower portion or edge of the cover A is provided with lugs or flanges fitting
into corresponding grooves upon the upper edges of the reservoir B and holding the
cover A and reservoir B together so as to be oil tight.
The reservoir B has hinged to its bottom the levers F with their connecting bars ff
attached to which is the spring G. The force of the spring conveys a vertical power
to the levers so that a longitudinal movement of the reservoir or box is prevented.
1) represents the wick in position. It is not intended that the details above referred
to are to be followed strictly the essential features of the invention consisting in
making the lubricator in two parts so that it can be placed in and taken from the
journal-box with ease, providing means of holding the top surface of the lubricator
against the journal or axle by means of a spring or springs placed under the
lubricator box, and supplying the oil from the reservoir to the axle or journal by
means of wicks which draw up and supply only the needed quantity of oil as the
journal revolves in contact with the upper surface of the wick.
Having now particularly described and ascertained the nature of this Invention
and in what manner the same is to be performed I declare that what I claim is :-
First:--A lubricator consisting of two parts, the upper part holding a wick or
other capillary conductor, and provided with an oil inlet at one side and the lower
part constituting the oil reservoir, the two parts being so arranged in relation to
cach other, that they can be placed in and removed from the journal box at will,
said lubricator being held in position in the journal box substantially as hereinbefore
set forth.
Second: A lubricator consisting of a box or reservoir B, with a cover A having a
concave upper bearing surface, a holder or opening C a wick or capillary substance D
and levers F and spring or springs G substantially as hereinbefore described and
illustrated in the accompanying drawings.
Third A lubricator consisting of the oil reservoir B the cover A having a
concave upper surface a holder C, the wick or capillary substance D the oil inlet E
with the cover e and spring e¹ substantially as herein before described and illustrated
in the accompanying drawings.
a
Fourth A lubricator consisting of the oil reservoir B the cover A having
concave upper surface, a holder C, wick or capillary substance D levers F and spring
or springs G and the oil inlet E provided with the cover e and spring e' substantially
as hereinbefore described and illustrated in the accompanying drawings.
