IMPROVE- MENTS IN SIGHT Feed LUBRICATORS
Year: 1885

page_text: I JOHN THOMAS HAILWOOD of Ramsey Street Rochdale in the county of
Lancaster Engineer do hereby declare the nature of my invention for IMPROVE-
MENTS IN SIGHT Feed LUBRICATORS to be as follows:-
I employ a hollow vessel to contain the oil or other lubricant, this vessel has a
hole formed in it at or near the bottom for the lubricant to pass out of the vessel,
in this hole a tube may be inserted, the top of which reaches to the top or nearly
so of the hollow vessel, at or near the bottom of this hollow vessel is formed a hole
or holes in the tube for the lubricant to pass out of the hollow vessel into the tube,
when it has passed the tube or through the hole at or near the bottom of the
vessel, it passes through a tap or valve and thence through a tube or nozzle which
is placed inside a glass tube, when the lubricant may be seen dropping from the
end of this tube or nozzle, as the end of the tube or nozzle can be seen through
the glass tube. When the oil or other lubricant drops to the bottom of the glass
tube it passes through a valve or tap and thence to the Engine &c in any
convenient manner by these means oil or other lubricant may pass to the Engine
by its own gravity or be drawn by the vacuum or be forced by the steam.

Improvements in Sight Feed Lubricators.
I JOHN THOMAS HAILWOOD of Ramsey Street Rochdale in the county of
Lancaster Engineer do hereby declare the nature of my invention for IMPROVE-
MENTS IN SIGHT FEED LUBRICATORS and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
I employ a hollow vessel, to contain the oil or other lubricant, this vessel has a
hole formed in it at or near the bottom for the lubricant to pass out of the vessel,
in this hole a tube may be inserted the top of which reaches to the top or nearly
so of the hollow vessel, at or near the bottom, of this hollow vessel is formed a
hole or holes in the tube for the lubricant to pass out of the hollow vessel into the
tube, when it has passed the tube or through the holes at or near the bottom of
the vessel it passes through a tap or valve (by which the quantity passing is
regulated) and thence through a tube or nozzle which is placed inside a glass tube,
when the lubricant may be seen dropping from the end of this tube or nozzle as it
can be seen trough the glass tube. When the lubricant drops to the bottom of
the glass tube it passes through a valve or tap and thence to the Engine or surface
requiring. lubrication in any convenient manner. By these means oil or other
lubricant will pass to the article requiring lubrication by its own gravity or be
drawn by the vacuum or be forced by the steam. In some cases the valve or tap
under the glass tube is not required. To make my invention better understood, I
will now proceed to describe the same by reference to the accompanying Drawing.
Figs. 1 and 2 are elevations (shown partly in section) of two different ways of
carrying out my invention and Figs. 3 and 4 (also in section) show the valve that
regulates the quantity of lubricant that passes from the hollow vessel applied in a
different way. Similar letters in all the Figures represent similar parts. a is the
hollow vessel into which the oil or other lubricant is placed, b Fig. is the tube
which is fixed inside the hollow vessel, and c are holes through the side of the tube
near the bottom of the hollow vessel through which the lubricant passes out of the
hollow vessel. In Figs. 1, 3 and 4 the hole c through which the lubricant passes
out of the hollow vessel is made in the bottom of the vessel and has no tube
inserted in it as shown in Fig. 2. The quantity of lubricant passing out through
the holes c is regulated by means of the valve d. When the lubricant has passed
the valve d it passes down to the end of the nozzle b¹ from which it drops, and
as the end of the nozzle can be seen through the glass tube f the quantity of
lubricant passing out of the hollow vessel a can be seen and regulated as required.
g Fig. 1 is a valve placed below the glass tube, by means of which the action of
the steam or vacuum on the lubricator can be regulated, when the lubricator is
applied to lubricate slides or pistons that move in steam or in a vacuum. Where
the surfaces requiring lubrication do not work in steam or in a vacuum the valve
or tap g below the glass tube is not required as the lubricant will descend out of
the hollow vessel by its own gravity and the lubricator shown in Fig. is most
suitable. Fig. 1 is a valve by means of which the hole i (in which the tube j is

page_text: inserted) can be opened or closed, this tube reaches to the top or nearly so of the
hollow vessel a and has no holes through its sides for the lubricant to pass into it,
but simply a passage through the tube from end to end. When this lubricator is
applied to lubricate the slides or piston of a steam or.other Engine if the oil or.
other lubricant in the hollow vessel a is thick or viscid, the valve or tap h (see
Fig. 1) is opened so as to allow the steam or heat to pass up the tubej into the
vessel a so as to warm it when the oil or other lubricant will become thinner or
more liquid and thus flow more easily out of the vessel a.
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:-
The arrangement of lubricators with the glass tube (through which the lubri-
cant can be seen passing) below the hollow vessel containing the lubricant, which
lubricant passes out of the hollow vessel and through the glass tube by the action
of its own gravity, or by a vacuum, substantially as herein shown and described.
