PROVISIONAL SPECIFICATION.
Improvements in Lubricators.
I, JOHN REBMANN, in firma Wanner & Company, of Horgen Switzerland, do hereby
declare the nature of this invention to be as follows:-
This new self acting lubricator is constructed in such a way that the grease is
submitted to the pressure of a spring as well as to that of a screw.
The bottom of the lubricator provided with a screw thread is screwed to that
part of the machine which is to be lubricated, by means of a prolongation or
nozzle. The cover forming one piece with the cylindrical part is perforated for
the passage of the piston-rod. The piston is influenced by the pressure of a spiral
spring which bears at one end against the cover and at the other end against the
piston.
In order to fill the lubricator the cylindrical part is screwed off the bottom the
piston is brought into the highest position wherein it is retained by a pin passing
through the piston-rod and resting on the cover. The cylindrical part when filled,
is screwed over the bottom the pin is drawn out and the spring now effects a
continual pressure upon the piston and through it upon the grease which is pressed
out through the outlet passage to the parts to be lubricated.
During the extension of the spring its pressure decreases and in order to obtain a
regular pressure from the beginning to the end of the filling the cylindrical part is
screwed down further on to or over the bottom from time to time.
This re-compressing of the spring may be continued till the lubricator is
empty.

COMPLETE SPECIFICATION.
Improvements in Lubricators.
I, JOHN REBMANN, in firma Wanner & Company, of Horgen, Switzerland, 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 new self-acting lubricator is constructed in such a way that the grease is
submitted to the pressure of a spring as well as to that of a screw. The said apparatus
is represented in longitudinal section in Fig. 1 and in elevation in Fig. 2 of the
accompanying drawings.
The bottom A of the lubricator provided with a screw thread a is screwed to
that part of the machine which is to be lubricated by means of a prolongation or
nozzle a. The cover b forming one piece with the cylindrical part B is perforated
for the passage of the piston rod c. The piston C is influenced by the pressure
of a spiral spring c¹ which bears at one end against the cover b and at the other
end against the piston C.
In order to fill the lubricator the cylindrical part B is screwed off the bottom A
the piston is brought into the highest position wherein it is retained by a pin
passing through the piston-rod at e and resting on the cover b. The cylindrical part B
when filled is screwed over the bottom A the pin is drawn out from e and the spring ci
now effects a continual pressure upon the piston C and through it upon the
grease D which is pressed out through the outlet passage a² to the parts to be lubricated.
During the extension of the spring its pressure decreases and in order to obtain a
ID 21

page_text: regular pressure from the beginning to the end of the filling, the cylindrical part B is
screwed down further on to or over the bottom A from time to time.
This re-compressing of the spring may be continued till the lubricator B is
empty.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is;
A self-acting lubricator for greases regulated by the combination of a screw and a
spiral spring in such a way that the spring e' ac'ing upon the piston is re-inforced
by screwing the box B over the hottom A substantially as and for the purpose described
and illustrated in the accompanying drawings.
