COMPLETE SPECIFICATION.
Improvements in Lubricating Apparatus, particularly applicable
for Lubricating the Cylinders and other parts of High Pressure
Steam Engines.
We, SIGMUND MERTZENFELD, and RALPH WRIGHT, both of the Ismailovski
Manufacturing Company, of Moscow, in the Empire of Russia, Engineers, 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:—
Our invention relates to improvements in lubricating apparatns particularly
applicable for lubricating the cylinders and other parts of high pressure steam engines,
and the object of our improvements is to admit any desired quantity of oil regularly
to a steam cylinder.
In the accompanying sheet of drawings.
Fig. 1 is a sectional elevation, Fig. 2 part of a plan view, and Fig. 3 a sectional end
view of our improved lubricating apparatus, and Fig. 4 is a sectional view, on the
line A A, Fig. 2.
In these views, - -a is a box or reservoir to hold a supply of oil or other lubricant,
and b a ratchet lever pivoted to a shaft c carried by the side of the box; on the shaft c
is secured a ratchet wheel d and into the teeth of this wheel is geared a pawl e
pivoted to the lever b; also secured on the shaft c is a pinion f which gears into a
wheel g mounted upon a stud h bolted to the box a and to this wheel g is secured an
eccentric pin i which enters a slot cut in the cross head j¹ of a plunger which works
in a pump barrel or cylinder k, see Fig. 4. The cylinder k is in communication
through a hole and passage k¹ with the lubricant in the box and from the bottom of
the cylinder there is a passage leading through a non-return valve m to a
pipe n.
When the apparatus is set in motion by actuating the ratchet lever 6 from any
convenient moving part, lubricant is drawn into the cylinder k, through the
passage k, as the plunger j is raised, and when the plunger descends it closes the
passage k¹ and forces the lubricant along the passage under the non-return valve m
and through the pipe n to the engine cylinder or other part to be lubricated.
By regulating the amount of movement given to the ratchet lever b a greater or
smaller quantity of lubricant can be fed through the pipe n.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In combination, the box a for lubricant, the pump barrel or cylinder kin
communication with the lubricant in the box through the passage k¹, the plunger j
actuated by the means shown or equivalent means and the delivery passage and pipe
controlled by a non-return valve substantially as herein set forth.

page_text: 2. The general combination and arrangement of parts embodying our improvements
in lubricating apparatus of the type indicated substantially as and for the purposes
herein described with reference to the accompanying drawings.
