COMPLETE SPECIFICATION,
An Improved Lubricator.
I, GUSTAV HÜLLSTRU UG, of 185, Furstenwall, Dusseldorf, in the Province of
the Rhine, Kingdom of Prussia, German Empire, Mechanician and 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 follow-
ing statement:-
My invention relates to an improved construction of lubricator adapted for
use in connection with any form or type of engine or machine the parts of which
require to be constantly or periodically lubricated.
In the accompanying drawings Figs. 1 and 2 are both vertical central sections
of my improved lubricator, the former showing its position when the lubricant
is shut off from the parts to be lubricated thereby, or when charging the supply
chamber with the lubricant in use, while the latter view shows its position when
in action.
My invention consists of a coned or tapered metallic or other body A, provided
at its lower end with a flange B, and externally threaded nosing C, to facilitate
its attachment to the part of the machine or apparatus it is intended to lubricate,
while its upper end has a like flange B and threaded extension or nosing C¹
for the reception of a cup or funnel D.
Upon the coned or tapered body A is mounted a sleeve or jacket E adapted to
form an annular chamber F, the said jacket while fitting oil-tight upon A is
nevertheless capable of being rotated thereon by the means of a handle G, screwed
thereon or thereinto, preferably in such a position that when disengaged from F
facilities are provided for getting to the interior of this chamber for cleaning and
other purposes.
At any convenient part of the chamber F I provide two apertures H and J.
the former of which is in such a position that when the handle G and chamber F
are placed upon the body A as at Fig. 1, the said aperture is in communication
with a passage K passing upward through the body A and communicating with
the cup or funnel D, while the latter aperture (J) communicates with a passage Li
passing downward through A B and C when the handle G and chamber are in the
position upon A shewn by Fig. 2. The manner of operation is as follows.
The oil or other liquid lubricant employed would be fed into the cup or
hopper D, when, if the handle G be operated until the chamber F is brought to
the position shewn by Fig. 1, the said lubricant would pass through the passage K
and aperture H and so fill the chamber F, if now the chamber F and handle G
be brought round to the position shewn by Fig. 2, the blank part of the sleeve
or jacket E would close the aperture or passage K, while the lubricant in F would
flow through the aperture J into and through the passage L to where required,
until the chamber F is emptied, when by bringing the handle G again into the
position shewn by Fig. 1 the chamber F may be again recharged in the manner
described.
From the foregoing it will be understood that the feed of the lubricant through

page_text: the passage
may be adjusted to any degree by regulating the extent of com-
munication between the aperture J in F and the entrance to the passage L in A.
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 herein described lubricating device consisting of the combination of a fixed
body A tapered externally, and carrying a sleeve or jacket E, adapted to provide
an annular chamber F, having apertures J and H arranged to communicate
with a passage K in A leading from a cup or funnel D for charging the chamber F,
or with a passage L in A for emptying the chamber F' and conveying the lubricant
to where required, the said chamber F and sleeve E being rotated upon A by the
means of a detachable handle G, substantially as herein described and shewn.
