THOMAS. SANDIFORD 22 Liley Street Rochdale in the County of Lancashire
Brass Finisher do hereby declare the nature of this invention for AN IMPROVE-
MENT IN SIGHT FEED LUBRICATORS OR AUTOMATIC OILERS FOR STEAM ENGINE,
to be as follows:-
.
A small tube or tubes is carried from the service pipe direct to the inside top
of condensing chamber which serves as a heating pipe for the condensed water
therein the hot water than passes through an apeture into the oil cestern or
chamber below which readly disolves tallow or thick oils.
THOMAS SANDIFORD.

page_text: The principle object of my invention is to furnish a means whereby thick oils
or tallow can be kept in a liqued state and maintain heat in the oil cestern or
chamber vareing between 50 and 70 degs. Fahr. above the surrounding atmosphere
thereby causeing the oil to feed regular.
Such being the nature of my invention I will now proceed to describe the
manner in which the same is to be performed and in order that the same can be
throughly understood I have annexed sectional Drawing Fig. 1 and 2 being front
& side elevations.
A is a cistern or oil chamber through which oil is admitted at valve B. In the
cestern or chamber the oil is forced down tube C to passage D by the pressure of
condensed water in condenser L. The glass tube F is filled with water at valve G
the oil being forced in the glass it accends to to the small passage H which is
regulated by valve I through which the oil is forced into steam service pipe K
which is constructed large enough so that the oil will fall of it own gravity to the
main steam pipe or valve box of engine.
J is a valve to allow the condensed water to pass into oil cistern or chamber A
passing down the tube J. 1. the water forceing the oil down tube C to jet D to
colum of water in glass tube F where it accend to passage H into large service
pipe K where it fall through the steady steam of its own gravity.
L is a condenser by which the steam is condensed which passes up tube M from
service pipe K.
M is tube or tubes carred from service pipe K through which the steam is
conducted to the top of condenser L acting as a heating pipe to keep the condensed
water at the heat it is condensed at, the hot water then desend down passage E
to the bottom of oil cistern or chamber A by means of valve J whice will keep
thick oil or tallow in a liqued state. N is an expansion joint to allow of the
unequal expansion in the two tubes K and E.
O is a valve to drain water off when emtey of oil.
P is a gland tap which is coupled on main steam pipe or valve box is merely is
case of accident to the lubricator.
Haveing now particular described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is,
In a sight feed lubricator or automic oilers, the small tubes or tube M carried
from the steam service pipe K direct to the inside top of condencing chamber L
which serves as a heating tubes or tube for the condensed water and as a conductor
of steam to the condencer as specified.
