PROVISIONAL SPECIFICATION.
Improvements in Lubricating the Cylinders of Steam Engines, and
Apparatus therefor.
I, HEINRICH GÖRD HAUSMANN, of Ost Zee Dyk, 32, Rotterdam, in the
Kingdom of Holland, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to the lubrication of the cylinders of steam engines and
more particularly the cylinders of compound engines.
Hitherto in lubricating the cylinders of compound engines it has been usual to
introduce into the high pressure cylinder a certain quantity of lubricant which,
mixing with the steam, is carried by it into the low pressure cylinder or cylinders.
This arrangement is objectionable inasmuch as that if only a sufficient quantity
of lubricant is introduced to properly lubricate the high pressure cylinders it
follows that owing to the greater area of the low pressure cylinder or cylinders
this or these is or are not sufficiently lubricated. If on the other hand a sufficient
lubricant is introduced to properly lubricate the low pressure cylinders then the
high pressure cylinder is necessarily over-lubricated.
According to my invention I introduce into the high pressure cylinder the proper
quantity of lubricant for lubricating this cylinder and as the steam passes from
one cylinder to the other an additional quantity of lubricant is furnished corre-
sponding to the differences of area to be lubricated.
A suitable arrangement of apparatus for carrying out my invention comprises a
small pump which draws the lubricant from a suitable reservoir and delivers it
into a chamber having two or more passages in communication with the respective
cylinders, the said passages being consecutively opened so that the required
quantity of lubricant is supplied to each cylinder in a regular manner.
This may
be advantageously effected by the employment of a rotating plug having in it a
port or opening for each of the said passages the said plug being rotated in any
suitable manner such as by gearing from the shaft driving the pump. The areas
of the openings through which the oil is forced must be proportioned to the pressure
in the respective cylinders.
Although I have described my invention as applied to a compound engine it will
be obvious that it will be applicable to an engine having two or more cylinders not
compounded.

Improvements in Lubricating the Cylinders of Steam Engines, and
Apparatus therefor.
I, HEINRICH GÖRD HAUSMANN, of Oost Zee Dyk, 32, Rotterdam, in the
Kingdom of Holland, 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 the lubrication of the cylinders of steam engines and
Inore particularly the cylinders of compound engines.

page_text: Hitherto in lubricating the cylinders of compound engines it has been usual to
introduce into the high pressure cylinder a certain quantity of lubricant which
mixing with the steam is carried by it into the lower pressure cylinder or cylinders.
This arrangement is objectionable inasmuch as that if only a sufficient quantity of
lubricant is introduced to properly lubricate the high pressure cylinders it follows
that owing to the greater area of the lower pressure cylinder or cylinders this or
these is or are not sufficiently lubricated. If, on the other hand, a sufficient
quantity of lubricant is introduced to properly lubricate the low pressure cylinders
then the high pressure cylinder is necessarily over lubricated.
According to my invention I introduce into the high pressure cylinder the proper
quantity of lubricant for lubricating this cylinder and as the steam passes from one
cylinder to the other an additional quantity of lubricant is furnished corresponding
to the differences of area to be lubricated.
A suitable arrangement of apparatus for carrying out my invention comprises a
small pump which draws the lubricant from a suitable reservoir and delivers it into
a chamber hereinafter termed the oil chamber having two or more passages in
communication with the respective cylinders, the said passages being consecutively
opened so that the required quantity of lubricant is supplied to each cylinder in a
regular mauner. This may be advantageously effected by the employment of a
rotating plug having in it a port or opening adapted to successively place the
various passages in communication with the oil chamber, the said plug being rotated
in any suitable manner such as by gearing from the shaft driving the pump, which
shaft is most advantageously driven by the engine.
To enable my invention to be fully understood I will describe an apparatus
suitable for lubricating a quadruple expansion engine, Figure 1 being a sectional
plan; and Figure 2 a section on the line 2-2, Figure 1; Figure 3 is an elevation
of mechanism which may be used for imparting motion to the apparatus.
a is the bed-plate of the apparatus, and b is a pump cylinder fixed thereon, the
plunger e of which is driven by a crank or eccentric e upon the shaft e rotating
in bearings in the frame a. The cylinder ò does not communicate directly with
the suction passage f of the pump but communicates first with the oil chamber g
through a passage h and thence with the suction pipe through the passage i, a
slide-valve which is also operated by a crank or eccentric upon the shaft e serving
to alternately place the passages h, in communication through a recess k in its
face and the passage h in communication with the chamber 9. The driving cranks
or eccentrics of the pump and the valve are so arranged that during the suction
stroke of the pump the passages h, i are in communication, as shown, and that
during the delivery stroke of the pump the passage h is uncovered, whereby the
lubricating oil is delivered into the chamber g. 1 is a spring which is attached to
the valvej and by pressing against one of the walls of the chamber g serves to
retain the valve j in contact with the face against which it works.
m is the casing of the cock and n is the plug working in the said casing, the
said plug being driven from the shaft e through the medium of the bevel pinion o
and the bevel-wheel . The casing m has in it four passages q, q', q², q³ com-
municating with the cylinders to be lubricated and the plug n which is made
hollow communicates with the oil chamber g through the passager and has a
holes therein designed to successively place the passages 9, q', q, q³ in communi-
cation with the said oil chamber.
With this arrangement it will be understood that at each quarter of a revolution
of the plug one of the passages q, q', q², q³ will be placed in communication with
the oil chamber so that for each revolution of the plug communication is established
The gear-
once between the chamber g and each cylinder to be lubricated.
wheels o, p are so proportioned that the pump will make four delivery strokes
during one revolution of the plug whereby each time the chamber g is placed in
communication with one of the cylinders a supply of oil will be injected.
The quantity of oil injected into the several cylinders may be varied by altering
the throw of the eccentric e which is slotted at e¹ to admit of increasing or

page_text: decreasing its eccentricity relatively with the shaft e, a set screw e passing through
a disc e³ fixed on the shaft e and entering the eccentric serving to fix the latter
in any desirable position upon the shaft.
Any suitable means may be employed for imparting motion to the apparatus.
As shewn in Figure 1, the shaft e carries a spur-wheel u with which engages a
spur-pinion v fixed to a pulley w driven from the crank-shaft of the engine or some
other suitable part; or a ratchet wheel x may be fixed on the shaft e and operated
by an oscillating lever y carrying a pawl z as shewn in Figure 3.
Although I have described my invention as applied to a compound engine it will
be obvious that it will be applicable to an engine having two or more cylinders not
compounded, or to a compound engine having more or less than four cylinders, the
casing m in all cases having a number of passages corresponding to the number of
cylinders to be lubricated.
It will thus be seen that by my apparatus which is automatically driven by the
engine, the cylinders are consecutively lubricated by a single pump and a single
cock with the quantity required for each cylinder and that if the cylinders have
different working pressures varying even say from 0.1 to 15 atmospheres this will
not affect the delivery of the oil which automatically takes place in the quantities
the apparatus is adjusted to supply to each cylinder.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. An apparatus for consecutively lubricating the cylinders of a steam engine
with the quantity requisite for each cylinder comprising a pump and a cock having
a rotating plug which successively places the oil chamber in communication with
the cylinders to be lubricated, substantially as described.
2. The improved apparatus for lubricating the cylinders of steam engines
herein before described and illustrated in the accompanying drawing.
