Improvements in Lubricators.
I, CHARLES REGINALD WINN Mechanical Engineer of 140 Granville Street,
Birmingham do hereby declare the nature of this invention to be as follows:-
My present invention relates to improvements in the construction of lubricators
of the sight feed type, which as at present constructed are in many instances bulky
and complicated.
My invention relates to the manner in which I construct the details of sight feed
lubricators and combine together the various parts in such fashion as to construct a
more efficient and compact lubricator than those hitherto in use.
To lessen the number of parts, and to obtain the compactness mentioned, I mount
the lubricator container upon a suitable body in which is contained a cock having
two independent passages in the plug of same, that is to say a diagonal passage and
also a right angle passage communicating with suitable port-ways in the body, in
such a way as to enable the cock to perform the double function of shut-off cock
for water supply from the condenser, and also as a drain cock to discharge waste
water from the container. This improvement is applicable to lubricators with one
or more sight feeds for the object herein detailed.
Under certain circumstances much difficulty is experienced in obtaining a steady
feed of oil, more especially with lubricators having two or more feeds, owing to
their having unequal pressure upon the delivery sides of the sight glasses as in
To obviate this
compound, triple expansion or other multiple cylinder engines.
difficulty I fit a resistance valve in the oil delivery pipe or pipes, which I load in
any convenient way, preferably by means of a spiral spring, by means of which
valve when suitably adjusted, equal pressure or resistance is obtained upon each oil
outlet of the lubricator. This valve is specially advantageous when fitted to the
oil delivery pipe or pipes of lubricators delivering into receivers, valve casings, or
other parts in which the pressure is very slight or below atmospheric pressure.
To facilitate and cheapen the repair, when necessary of the oil filling plug and
seat I provide a filling cup or dish formed in a separate piece from the container
into which it is screwed, the said cup or dish having a seat formed upon the inside
and which is also screwed to receive the filling plug. Thus transferring the wear
of the joint face and threads usually formed in the container itself, to the detachable
filling cup herein mentioned; the cup admitting of easier and less expensive repair
or renewal than as hitherto constructed.
I form the head of the plug of the condenser, also the oil filling plug for the
container, and the plug for filling the sight glass, with suitable size hexagon or
other shaped heads, and for which I provide a suitable double-ended spanner,
preferably of the closed end type, thus facilitating their removal with a minimum
of wear.

I, CHARLES REGINALD WINN Mechanical Engineer of 140 Granville Street,
Birmingham in the County of Warwick 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 present invention relates to the manner in which I construct the details of
sight feed lubricators and combine together the various parts in such fashion as to
construct a more efficient & compact lubricator than those hitherto in use.
In order that my invention may be clearly understood & more easily carried into
practice I have appended hereunto a double size sheet of drawings upon which:
Figure 1 is a front elevation of the sight feed lubricator and
Figure 2 is a part sectional side elevation of the same.
Figure 3 is a sectional view of the filling plug to container.
Figure 4 is a sectional view of the filling plug to condenser.
Figure 5 is a longitudinal section of resistance valve.
Figure 6 is an elevation of spanner.
To lessen the number of parts & to obtain the compactness mentioned I mount
the lubricator container F upon a suitable body O Figure 1 & 2 in which is
contained a cock X having two independent passages in the plug of same that is to
say a diagonal passage P and a right angle passage R communicating with suitable
portways S in the body O in such a way as to enable the cock X to perform the
double function of controlling the water supply from the condenser C & the
discharge of waste water from the body O through union Y.
To facilitate & cheapen the repair when necessary of the oil filling plug and seat
I provide a filling cup or dish E shown more clearly at Figure 3 & formed in a
separate piece from the container F into which it is screwed, the said cup or dish E
having a seat e¹ formed upon the inside & which is also screwed at e² to receive the
filling plug E. Thus transferring the wear of the joint face & threads usually
formed in the container itself to the detachable filling cup E, the cup admitting of
easier & less expensive repair or removal than as hitherto constructed.
Referring to Figure 4 it will be seen that to enable the air to be readily discharged
from the condenser C I have arranged a valve spindle B with a hole b¹ bored the
greater part of its length which meets a second hole bored at a right angle and
communicating with a chamber 63 above the valve seating, thus by easing the valve
from its seating the air & steam will be discharged vertically without risk to the
operator and by removing the valve entirely the condenser can be filled with
water.
Under certain circumstances much difficulty is experienced in obtaining a steady
feed of oil more especially with lubricators having two or more feeds owing to their
having unequal pressures upon the delivery sides of the sight glasses as in
compound, triple expansion or other multiple cylinder engines. To obviate this
difficulty I fit a resistance valve, Figure 5, in the oil delivery pipe or pipes which I
load in any convenient way, preferably by means of a spiral spring as shown, by
means of which valve when suitably adjusted equal pressure or resistance is obtained
upon each oil outlet of the lubricator. This valve is specially advantageous when
fitted to the oil delivery pipe or pipes of lubricators delivering into receivers, valve
casings or other parts in which the pressure is very slight or below atmospheric
pressure.
I form the head of the plug B of the condenser, also the oil filling plug e¹ for the
container & the plug for filling the sight glass with suitable size hexagon or other
shaped heads & for which I provide a suitable double ended spanner, T preferably
of the closed end type, thus facilitating their removal with a minimum of wear.
