I, EMIL SONNENTHAL, of 54 Kochstrasse, Berlin, in the Empire of Germany,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in cans for holding and discharging solidified
lubricants, and has for its object to enable the person using the can to carry and operate
same with one hand.
The invention consists in forming a cylindrical body with an outlet at the bottom
and a cover at the top, and handle at the side. Inside this cylindrical body I employ
a piston, the rod of which is formed rack-like and passes through the said cover.
Inside the latter I pivot a lever which passes through a slot to near the handle of
the can.
This lever is under the control of a spring and has a ratchet pawl attached, which
acts upon the rod of the piston.
When the free end of the lever is depressed by the thumb, the piston forces the
lubricant down and discharges same through the outlet of the can.
Dated this 15th day of August 1887.

page_text: I, EMIL SONNENTHAL of 54B Kochstrasse, Berlin in the Empire of Germany,
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:-
My invention relates to improvements in cans for holding and discharging solidified
lubricants, and has for its object to enable the person using the can to carry and operate
same with one hand.
And in order that my invention may be better understood I have caused to be
appended hereunto one sheet of drawings, showing a vertical cross section of
the can.
In carrying out my invention the improvement consists in forming a cylindrical
body a with an outlet at the bottom and a cover c at the top, and handle dat
the side.
Inside this cylindrical body a I employ a piston e the rod e¹ of which, is formed
rack-like and passes through the said cover c.
Inside the latter I pivot a leverf which passes through a slot formed in the cover c
near to the handle d of the can.
This lever is under the control of a spring g which bears against a partition c
formed in the cover c, and has a ratchet pawl attached, also under the control of a
spring g which acts upon the rack part of the rod e¹ of the piston e.
When the free end of the lever f, is depressed by the thumb, the piston e forces the
lubricant down, and discharges same through the outlet of the can.
The knob serves to lift the piston e when required.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim, is:―
The combination of the cylindrical chamber a provided with a handle d, with a
piston e the rod e¹ of which is formed rack like and acted upon by a pawl h attached
to a lever f, which lever f when depressed by means of the thumb of the hand holding
the can, causes the piston e to force the substance out of the can, substantially as & for
the purpose specified.
