Improvements in or relating to Lubricators.
I, EDWARD WHALLEY of Grundy Street, Golborne, in the County of Lancaster
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:—
This invention has for its object an improved lubricator and devices for regulating
the flow of oil from the cup or reservoir of the same to the shaft or other parts of
machinery requiring lubrication.
The invention will be best understood by referring to the accompanying drawing,
in which,
Figure 1 is an elevation partly in section of the lubricator and regulating
devices;
Figure 2 an elevation and plan of a portion of the regulating device ;
Figure
a section on line xx, Figure 1, looking in the direction of the arrow.
In these figures→
A is an ordinary lubricator cup or reservoir, B the entrance for oil and Ca plug
closing the same. Across the entrance is a piece of wire gauze or perforated
metal D supported in any suitable manner (preferably by a flange d as shown) its
object being to filter the oil as it is being poured in. E is a screwed pin, preferably
of larger diameter than the passage e, which completely stops any flow of oil down
the latter when screwed up as shown. By withdrawing this screw which has a
very fine thread, the flow can be regulated to a nicety, in fact if a complete
revolution of the screw be made, it will only leave a passage equal to the distance
between two threads.
F is a lever pivoted at f. This lever is composed of two parts as shown in
Figure 2, the arm fbeing formed hollow to receive the reduced portion ", or,
in other words, being telescopic. G is a screw connecting the two parts. The
object of this is to allow of the lever being varied in length to suit different widths
of bearings. His a pulley or disc rotatable on the stud h' and having a milled or
roughened periphery resting on the shaft H', Figure 3 (or on a drum mounted on
the shaft) and receiving rotation therefrom. This disc has an enlarged part or
projection which causes it to be raised at each revolution for purposes hereinafter
described. I is a slotted bar secured to the stud on which the disc H revolves, but
not intended to revolve itself. The end of arm f' is formed with an angle piece
which is adjustable on and can be secured to the slotted bar I. Should it be
necessary in actual adjustment to lower the disc H, the screw G is unfastened, and
the slotted har I withdrawn. The screw G' is also loosened and the hollow
arm rotated half a revolution, which brings the angle piece at the bottom, as
shown by dotted lines. The plotted bar is then re-inserted. It will be obvious
that this arrangement permits an increased vertical adjustment of the disc. The
end of arm F of lever F is formed as shown at F, Figure 2, to control the
passage e of the lubricator and is operated in a manner hereinafter described
whereby the flow of oil is intermittent.
The mode of action is as follows:-
Having adjusted the disc H vertically so as to rest on the shaft H¹ (or on a drum
mounted on the same) and horizontally to be clear of the bearings, also the screwed
pin E to allow the proper quantity of oil to flow, the shaft His rotated causing
the disc to rotate also. As the projection h comes in contact with the shaft at
each revolution, the lever F is raised on its pivot, momentarily lowering the arm F¹
and allowing the oil to pass down to the journal of the shaft. As soon as the
projection is clear of the shaft, the end F¹ of the lever rises and closes the passage,

page_text: until the disc has completed a revolution, when it is again opened, a small quantity
of oil being thus admitted at each revolution of the disc. It will be evident that
instead of forming a projection on the disc, the latter might be perfectly round
and the projection fixed on the shaft in the form of a stud, or the lever may be
actuated by some other moving part of the machinery, or the disc may have more
than one projection, the principal object of this invention being to so arrange the
parts that the machine itself shall regulate the flow of oil to its bearings. The
parts J for fixing the lubricator is shown split. By pressing it into the oil hole
of the bearing, it will, by its elasticity, keep the lubricator steady or it may be
screwed if desired.
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 a lubricator, the arrangement or construction of apparatus for supplying
the bearings with a regulated quantity of lubricant at each revolution of the
shafting, substantially as described.
2. The general combined arrangement and construction of parts forming my
improved lubricator substantially as set forth.
