Improvement in Lubricators for Semi-solid Lubricants.
I JAMES LUVIAN WADE of Manor House Wharf, Nine Elms Lane, in the
County of Surrey Manufacturing Chemist & Lubricating Grease Manufacturer 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 an improvement in lubricators for semi-solid lubricants
the object being to provide a simple and effectual means by which the quantity of
"Warner" and
grease in the cups of metal lubricators of the "Reisert," "Stauffer,"
such like types can be ascertained at a glance without the necessity of the cap
being unscrewed for that purpose thus ensuring a certain means of obviating the
heating of journals through the engineer not having been aware of the grease
supply having become exhausted.
A further object of my invention is to provide a strong & efficient substitute for
the expensive and fragile glass containers or lubricators which, until now, have
been the only ones whereby, the grease supply has been ascertainable without
unscrewing the cup.
In the accompanying drawings

"A" represents the body of the metal cup or grease container which is threaded
and has a milled edge. When this cup is filled with grease it is screwed on the
lower half of the lubricator marked " a & by turning the cup it descends and
slowly presses the grease through the hollow feed tube "," the outside of which is
also threaded to the various part of the machinery in need of lubrication. When
the cup has travelled half way the bottom of it becomes level with the words "half
full" (c) cast or cut on the shank of the feed tube & demonstrates the quantity of

accomplished a projecting arm or indicator marked "d" on the drawings intercepts
the cup while the word "empty" on an enlarged shank marked "e" on the drawings
immediately below the aforesaid indicator warns the engineer that the lubricating
supply has become exhausted. The action of the indicator at this juncture is shewn
in Figure 2. Below the enlarged shank above named is an hexagon "f" so con-
structed as to allow of the whole lubricator being removed with a spanner without
fear of injuring the indicator or obliterating the check words.
As it is possible that slight changes might be resorted to in the form &
arrangement of the parts described without departing from the spirit & scope
of my invention I do not wish to limit myself to the exact construction herein set
forth.
Having now particularly described and ascertained the nature of my inven-
tion & in what manner the same is to be performed I declare that what I
claim is
A lubricator-for semi solid lubricants provided with a projecting arm to indicate
effectually when the lubricant becomes exhausted.
