Improvements in Lubricators for Holding Grease or other Solid. or
Nearly Solid Lubricating Substances.
I RICHARD WITHINGTON BROMILEY SANDERSON of Office D Royal Exchange
Manchester in the County of Lancaster Cotton Merchant do hereby declare the nature
of said Invention for IMPROVEMENTS IN LUBRICATORS FOR HOLDING GREASE OR OTHER
SOLID OR NEARLY SOLID LUBRICATING SUBSTANCES, which Invention has been com-
municated to me from abroad by William Edgar Plummer of St. Louis Missouri
United States of America Engineer, to be as follows:-
This invention relates to improvements in lubricators for holding grease or other
solid or nearly solid lubricating substances and it consists in an improved construction
and arrangement of parts.
In carrying out the Invention the stem and flanged bottom plate are made in
one piece which is screwed into or otherwise secured to the box of the journal
or other part to be lubricated. The main portion or cup of the lubricator is
preferably cylindrical in form and screws into the flange of the bottom plate and
the neck of the cup has a screw thread cut in or on it; into this thread is
screwed a bush with a winged nut at the top which forms a cap to the cup
a separate winged nut is screwed on to the bush and bears upon the top of the
cup neck to lock the bush in the desired position. In the cup is fitted a piston the
rod or stem of which projects upward and passes freely through a hole in the cap and
a spring is coiled upon the stem one end of the spring bearing against the piston and
the other against the cap so that the spring exerts its force against the piston to force
the grease out of the lubricator automatically.
By slackening the locknut and adjusting the position of the bush and cap the spring
can be adjusted to put any desired pressure on the piston.

page_text: In order to regulate the quantity of lubricant delivered to the journal or other part
a valve is placed across the mouth of the hole in the stem; the valve stem can be
moved from the outside of the cup to effect the adjustment.
When the lubricator is to be refilled the cup is unscrewed from the bottom plate
and the cup when replenished is again screwed on to the flanged plate.

Nearly Solid Lubricating Substances.
I RICHARD WITHINGTON BROMILEY SANDERSON of Office D Royal Exchange
Manchester in the County of Lancaster Cotton Merchant which Invention has been
communicated to me from abroad by William Edgar Plummer of St. Louis Missouri
United States of America 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 :-
This invention relates to improvements in lubricators for holding grease or other
solid or nearly solid lubricating substances and it consists in an improved construction
and arrangement of parts.
And in order that this Invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of Drawings reference being had to the
figures and letters marked thereon.
Figure 1 is an elevation and Fig. 2 a sectional elevation of a lubricator constructed
according to this Invention.
The stem of the lubricator and the flanged bottom plate a are made in one
piece which is screwed into or otherwise secured to the box of the journal or
other part to be lubricated. The main portion or cup b of the lubricator is pre-
ferably cylindrical in form and is screwed into the flange of the bottom plate a
and the neck of the cup has an internal screw thread cut in it as shown or it
might be an external thread into which is screwed a bush c with a winged nut c¹
at the top which forms a cap to the cup. A separate winged nut d is screwed on to
the bush and bears upon the top of the cup neck 6' and so locks the bush in any
desired position. In the cup b is fitted a piston e the rod or stem e¹ of which
projects upward and passes freely through the bush e and a hole in the cap cand

page_text: a spring is coiled upon the stem e¹ one end of the spring bearing against the piston c
and the other against the cap c¹ so that the spring exerts its force against the
piston e to constantly and automatically force the grease out of the lubricator.
By slackening the locknut d and adjusting the position of the bush c by means of
the winged cape the spring can be adjusted to put any desired pressure on the
piston e and so increase or diminish the feed of lubricant at will.
In order to further regulate the quantity of lubricant delivered to the journal or
other part a valve g is placed across the mouth of the hole or passage in the stem a
so that the valve stem can be moved from the outside of the cup to effect the
adjustment.
When the lubricator is to be refilled the cup b is unscrewed from the bottom plate a
and the cup when replenished is again screwed on to the said plate.
Having now particularly described and ascertained the nature of this said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. In a lubricator for holding solid or nearly solid lubricating substances the
combination with a suitable casing, of a piston fitted therein and an adjustable spring
exerting a variable pressure upon said piston for the purpose of ensuring a constant
automatic feed of the lubricating substance substantially as herein set forth.
2. The combination of the combined stem and bottom plate, the cup b, bush c and
cap c', locknut d, piston e, spring fand valve g, all substantially as herein shown and
described for the purposes specified.
