An Improved Lubricating Apparatus for Steam Engines and other
Machinery.
I, PHILIPP HUBERT, of Budapest, in the Kingdom of Hungary, Manufacturer and
Merchant, 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 stateinent :-
The subject of this invention is an improved apparatus for injecting grease, to bo
employed in connection with machines but especially in locomotive, portable and
marine engines. The action of the said apparatus is continuous.
I will now proceed to describe the said apparatus with reference to the accompany-
ing drawings in which Figure 1. is a side elevation, Figure 2. a top view, and
Figure 5. a vertical longitudinal section, of the same, and Figures 3. and 4. are detail
drawings of parts thereof.
a. and a' are two horizontal pieces of metal of cylindrical form and equal size which
are provided with flanges for receiving screws whereby they are connected together.
The said pieces are formed in such a manner that their inner halves are each open on
each side and their outer halves form closed chambers for suction and forcing and are
each provided with a suitable tube or passage piece which acts alternately as inlet and
outlet for the grease.
b. and are two plunger pistons, which alternately suck, and press, and con-
sequently produce a continuous action."
In the interior of the case formed by the pieces a. and a' is arranged a circular
body on which is keyed a wormed ring d. This circular body is threaded at each end
(c. and c) with screw threads which fit into corresponding threads on the plungers b.
and 6 and serve to draw and drive them alternately.
The spindle c., which has its bearings in a plumber block and is provided with a
thread, gears into the worm wheel d. to produce the motion above referred to of the
two pistous b. and 6'.
One end of the said spindle e. is extended such extension carrying the ends of the
fork of the movable arm f. On the said extension are fixed, between the prongs of
the said fork, two ratchet wheels g. and g' which can be moved in opposite directions

page_text: by two clicks h. and which are also inside of the fork. The direction of motion
can be reversed by the action of the click h. on the ratchet wheel g. or the click h¹ on
the ratchet wheel g' and a right and left motion of the mechanism obtained.
On the round arm f. is an adjusting ring into which is screwed a ring to admit
of the connection by a cord or other suitable fastening of the arm f. with any suitable
part of the steam engine or other machine, in such a manner, that it may receive the
necessary throw or regulating adjustinent.
On the passage pieces, already referred to, of the two cylindrical bodies a. and a¹
are valves of the shape and construction shown at k. and each provided with three
orifices and two closing pieces. The orifices d' are connected by tubes with the grease
reservoir which can be fastened on any suitable place. The grease runs through the
orifices d'¹ to the orifices B. and passes thence through glass tubes to the common
crosspiece 7. which is screwed on the flanges of the cylindrical bodies a. and a¹. The
crosspiece 1. has an orifice L. through which the grease can be pressed to the object
to be greased.
In an orifice in each of the pieces k. k is arranged the pinscrew V which can
be caused to close the orifice B. and consequently the entrance to the glass tube, the
other closing apparatus s. closes the orifice d' and consequently prevents passage of
the
grease from the reservoir to the apparatus.
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 :—
First. In the construction of lubricating apparatus, the employment of two or more
cylindrical pieces of metal a. and a² of equal size, the inner half of each piece being
formed open and the outer half closed, (the said outer halves are each furnished with
a passage piece and are respectively provided with the valves k. and ¹) and of the
wormed ring d., the whole being constructed and arranged substantially as hereinbefore
described and shown in the accompanying drawings.
Secondly. In lubricating apparatus the construction and arrangement of tho
circular body with threaded arms c. and c¹ substantially as and for the purpose
herein before described.
Thirdly. In combination with machines of the nature referred to in the above
claims, the arrangement of the wormed spindle e., forked arm f., clinks h, and h³, and
ratchet wheels g. and g', substantially as, and for the purpose, hereinbefore described.
Fourthly. In lubricating apparatus of the nature above described, the employment
in connection with the closed halves of the pieces a. and a' of the valves k. and the
whole being constructed and arranged as and for the purpose herein before described.
And lastly. The combination and arrangement of parts constituting an improved
lubricating apparatus, substantially as, and for the purpose hereinbefore described.
Dated this 18th day of March 1887.
