PROVISIONAL SPECIFICATION.
Improvements in Condensation Lubricators.
I, DANIEL MCCALLUM, of 33 St. Andrews Street, Dundee, in the County of
Forfar, N.B. Brass-founder, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to simplify and improve the construction of float
feed lubricators, by arranging the parts in such a manner as to necessitate only one
connection to the steam pipe.
In carrying out my invention, I construct the oil reservoir and its immediate
appurtenances in a similar manner to other float feed lubricators, and confine my
improvements to the condensing chamber.
The lubricator is connected to the steam pipe at one point only, by a suitable
connection. Said connection consists of a branch to the lubricator (a), another to
the steam pipe (b), another in connection with the bottom of the oil chamber (c),
the fourth (d) and last being a branch to the steam cut off valve, which should be
closed if any part of the apparatus goes out of order. At right angles to these
said branches are two others, the lower (e) in connection with the feed glass, the
upper () being connected to the condenser. Attached to said upper branch (f)
are two smaller pipes, cach being indenpendently in connection with the steam pipe
and of such a length as to terminate near the top of the condenser although one of
the pipes should be somewhat shorter than the other, the shorter acting, as an over
flow when the condenser is full of water. There is a connection between the bottom
of the condenser and the previously described branch (c) which is in connection
with the bottom of the oil chamber, and is intended to permit the condensed water
to get underneath the oil.
P
If it is required to set the lubricator in operation after it has been attached to
the steam pipe I proceed as follows:-
First. I open all valves and blow steam through. Second, I close branches (c)
and (d) after which I open (d) and then shut the feed regulating valve in connection
with (). The reservoir can then be filled with oil, and when sufficient water has
condensed in the feed glass, the lubricator may be started by opening the com-
munication between (c) and the reservoir, in this manner allowing the condensed
water to flow from the condenser to the under side of the oil.

COMPLETE SPECIFICATION.
Improvements in Condensation Lubricators.
I, DANIEL MCCALLUM, of 33 St. Andrew's Street, Dundee, in the County of
Forfar, N.B. Brass-founder, 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 :-
The object of this invention is to simplify and improve the construction of float
feed lubricators, by arranging the parts in such a manner as to necessitate only one
connection to the steam pipe.
The accompanying sheet of explanatory drawings, illustrates the method of
carrying out my invention.
Figure 1. represents a section at A. A. of the lubricator,

page_text: Figure 2. a part plan showing the part D. and looking on C. C.,
Figure 3. a view of D. looking on B. B. and
Figure 4. a side view of the lower part of the pipe 16.
In these drawings the same reference letters and numerals are used to mark the
same or like parts wherever they are repeated.
In carrying out my invention, I construct the oil reservoir 4. and its immediate
appurtenances in a similar manner to other float feed lubricators, and confine my
improvements to the condensing chamber.
The lubricator is connected to the steam pipe 5. at one point only, by a suitable
connection 6. Said connection consists of a branch (a) to the lubricator, another (b)
to the steam pipe 5., another (c) in connection with the bottom of the oil chamber 4,
the fourth (d) and last being a branch to the steam cut off valve 7., which should be
closed if any part of the apparatus goes out of order. At right angles to these
said branches, are two others, the lower (e) in connection with the feed glass 8.,
the upper (f) being connected to the condenser 9.
Attached to said upper
branch (f) are two smaller pipes 10. and 11. each being independently in connection
with the steam pipe 5. and of such a length as to terminate near the top of the
condenser 9., although one of the pipes should be somewhat shorter than the
other, the shorter 10. acting as an overflow, when the condenser 9. is full of water.
There is a connection 12. between the bottom of the condenser and the previously
described branch (c) which is in connection with the bottom of the oil chamber
through 13., and is intended to permit the condensed water to get underneath
the oil.
If it is required to set the lubricator in operation, after it has been attached to
the steam pipe, I proceed as follows:-First:-I open all valves and blow steam
through. Second-I close branches (c) and (d) by means of the valves 14. and 7.,
after which open (d) 7., and. then shut the feed regulating valve 15. in con-
nection with (d). The reservoir 4. can then be filled with oil, and when sufficient
water has condensed in the feed glass 8. the lubricator may be started by opening
the communication between (c) and the reservoir 4., in this manner allowing the
condensed water to flow from the condenser 9. to the underside of the oil, by
passing through the pipe 16.
The quantity of oil passing into 8. is regulated by means of the valve 15. The
oil in the reservoir 4., as it is displaced by the condensed water which comes out of
the pipe 16., flows down the pipe 17. past the valve 15. to the feed glass 8. and
from thence through the pipe 18. to the steam pipe. 19. is a gauge glass for
showing the quantity of oil in the reservoir. 20. is the stopper which is removed
when the reservoir requires to be replenished. 21. is the valve for allowing the
condensed water to escape from the reservoir when a new supply of oil is required.
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) In condensation lubricators, the construction and arrangement of parts, by
means of which steam is condensed in the condenser, and then allowed to flow to
the oil reservoir, in this manner displacing the oil and sending it into the steam
pipe, substantially as described.
(2) In condensation lubricators, the method of connecting the lubricator to the
steam pipe, by means of one connection as shown.
(3) In condensation lubricators, the general construction, combination and
arrangement of parts, substantially as and for the purposes herein set forth, together
with any mere modification or modifications thereof.
