for Lubricating Journals, Shaftings, Stationary, Marine, and
Locomotive Engines, and other Machinery.
I, EDWIN DUNBAR BANGS, residing at Number 1522, Cedar Street, in the
City and County of Milwaukee and State of Wisconsin, in the United States of
America, Manufacturer, 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 invention has for its object the lubrication of journals, shaftings and other
portions of machinery, especially such as are connected with stationary, marine
and locomotive engines, and consists in certain peculiarities of construction,
whereby such lubrication only occurs when a lever connected to my device has
been moved by contact with a contact device upon a shaft or other moving part of
the machinery located beneath said oil-cup, thereby effecting a great saving of
oil, while yet keeping the parts sufficiently lubricated, all as hereinafter set forth
and illustrated in the accompanying drawings.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side elevation of one form of my device, shown attached to the
box or bearing of a shaft or journal, the latter being represented in section,
Figure 2 is a vertical section, on the line 2-2 of Figure 1, drawn to an
enlarged scale,
Figure 3 is a detail sectional view on the line 3-3 of Figure 2, taken at right
angles to the section line of the preceding figure,
Figure 4 is a detail section similar to Figure 3, but illustrating another form of
my present device, with an eccentric headed screw beneath, and
Figure 5 is a detail view of said eccentric headed screw.
B
A represents the cylinder of the cup, the upper part of which is externally
screw-threaded, as shown at a, for the reception of the correspondingly screw-
threaded depending circular flange b of the cap B, which latter has an upward
extending central neck C, having interior screw-threads for the reception of a
correspondingly screw-threaded plug D, having a central vertical perforation d,
for the admission of air into the cup, above the oil, and below this neck the сар.
is formed into a central feed hopper I, having a feed opening i, to one side of which
is a vent c, preferably diagonal, communicating with the interior of the cylinder A,
the under side of the described plug D being preferably hollowed out, as shown
at d', to increase the area of the air-cushion formed above the oil, in the
cylinder A.
The bottom of the cylinder is cast with a standard E, terminating in a
nib, F, having exterior screw-threads by means of which the cup is secured in
the desired position, there being a channel ff1 extending from a depression e in
the bottom of the cylinder down through the said standard and nib, and the said
standard is provided with a tapered transverse bore g for the reception of a plug G,
tapered as shown to correspond to the bore g, and the plug G is provided with an
angled channel h h', and in the form shown in Figure 3 with another branch h² to
said channel, for communication with the oil channel ff' and with the air-vent j¹
or vents as the case may be, the said vents being bored through the standard E
and communicating with the transverse bore g, and the outer ends of said vents
being enlarged and screw-threaded to receive the screws jj, which have holes of
less diameter than that of said vents bored therethrough so that the vents j¹ j
need not be of so minute a diameter as to render their boring difficult, and at the
rn.

same time the fine holes in the screws will serve to admit just the requisite amount
of air needed, and also serve to keep out the dirt.
The large end of the plug G is preferably reduced as shown at g', and thence
offsetted, continuing in a squared shank g² of less diameter, and terminating in a
screw-threaded end g³. The small end of said plug is reduced or offsetted, as shown
at g, and then again reduced, and terminated in a screw-threaded bolt g, and
when the plug G is in place within the bore g of the standard E, a flat spiral
spring is slipped on around the offset portion g against the end of the plug and
the standard, (to take up any slack occasioned by wear) and then a nut 97 is
screwed on the bolt go against the said spring, and a lock-nut 98 screwed on against
the nut g', as shown.
Secured to the outside of the cylinder A is a frame K with two projecting
bracket-armsk whose ends are perforated to receive the ends of a rod K¹ having
screw threads formed thereon, and retained in position by nuts ¹k. M is a feed-
lever having in its upper end a slot m, by which it is suspended from the said
rod K¹, there being a spring L and washer L' on each side of the said lever
surrounding the said rod K. Below this first slot, m, and at right angles thereto,
the said lever M is provided with another slot m' which receives the squared
shank g² on the adjacent end of the plug G, next to which is placed a washer g³,
and against this is screwed (on the end g³) a nut 910, thus ensuring a secure
connection between the plug G and feed-lever M.
In Figure 1, I show, as stated, my improved cup applied to the box or bearing
of a shaft, or journal, the nib F being screwed into the cap N of said box, and the
shaft or journal O being provided with a screw-threaded socket o for the reception
of a screw P having a cam-shaped head p, said screw P being adjusted to the
desired depth in said socket o, and then locked with a lock-nut n, the said head p
being in line with the lower end of the feed-lever M, so that, as the said shaft or
journal revolves, the head of the screw P will strike and move the lower end of the
feed-lever M and thus open the port or channel ' (or 2 depending upon which
way the said shaft is revolving) by bringing it in line with the channel f in the
base of the cylinder A, and permitting this channel ¹ (or 12) and its angled
continuation h, to become filled with oil, and then as the lower end of the lever M
is released from contact with the said screw-head p, the springs L L will instantly
bring said lever M to its original perpendicular position, thereby bringing the
part of said channel in line with the part f' of the channel in the standard E and
nib F, and the said channel branches in line with the air-vents j¹³ thereby
enabling the oil which was in he said channel ¹ (or 2) to drop down and out
through the channel f1 to the point to be lubricated, this action being repeated
with every revolution of the said shaft or journal, and as the part of the channel
in the plug G must necessarily be against some closed part of the wall of the
hore g, when either the branch 1 or 2 is taking oil from the cylinder (through
the upper part e fof the channel leading from the bottom of the cylinder A) it
follows that the oil cannot be fed out through the lower part of the channel (1)
until the part of the plug-channel is restored to its normal position (shown in
Figure 3) with the channel branches ¹² in communication with the air-vents j¹ j²,
so that the feeding is entirely automatic, and dependent upon the operation of the
machinery, and hence no oil can be fed while the machinery at rest, and therefore
there is no possible waste of oil.
The object of the described adjustment of the screw P is to regulate the feed,
as required, by increasing or decreasing the time that the lower end of the feed-
lever is in contact with the cam-head of the screw, and thus increasing or
decreasing the stroke of said feed-lever, and hence the branch ' (or h²) of the
plug-channel will be wholly or partly in register with the channel f above, and a
greater or less quantity of oil fed to the plug-channel at each revolution, in
consequence. The slots m. and m¹ in the feed-lever are made longitudinally (or
vertically) of considerable length to permit of the necessary adjustment of the
said lever, as when there is considerable distance between the oil-cylinder and the

page_text: cam-headed screw in the shaft or journal beneath, and in view of this adjustment
of the feed-lever, my device will be equally operative if the part which the lower
end of said feed-lever engages with is a fixed one, instead of an adjustable screw,
as described, the adjustment of the feed-lever being only the work of a moment,
the nut 10 being loosened for this purpose and then re-tightened.
In Figure 4, I show the channel in the plug G as being provided with only a
single branch, ', and the standard E consequently having only a single air-vent j',
in communication therewith. This form of oil cup is especially designed for use
in connection with the guides for the cross-head of a locomotive or other engine,
to which guides the nibs of two of these oil-cups are secured, and beneath each
oil-cup the cross-head Q is provided with a cam-head screw R (in this instance
projecting horizontally, as indicated best in Figure 5, the cam-head r of this form
of screw differing, as shown in Figures 4 and 5 from the form shown in Figure 1,
but the said screw being capable of turning around to vary the length of contact
between its head and the lower end of the feed lever above, for precisely the same
purpose as that set forth in connection with the other form. As less oil is needed
to lubricate a cross-head than a shaft or journal in this form the cup feeds only
with every other movement of the cross-head, that is, with every forward stroke
only, or every return stroke only, as the case be.
may
The screw R is provided with a lock-nut n, to hold it firmly in the desired
position after adjustment, which adjustment is easily accomplished by means of the
squared end on the cam-head.
While I have described and illustrated the preferable form of my improved
oil-cups, it will be understood that I do not limit myself to the exact details of
construction set forth. For instance, instead of the style of top or cover shown
I may employ simply flat or other caps hinged or pivoted to the cups, to fit tightly
and exclude dirt; again, if my oil-channels are made of sufficient size, the
described air-vents and perforated screws jj, are not absolutely necessary and
may be dispensed with, and in place of the described contact pins or screws, with
cam-shaped heads, any other suitable contact devices may be applied to the shafts
or other moving parts of machinery beneath the oil-cups, so as to ensure temporary
contact with the levers at the proper time, although the forms illustrated in the
drawings have been found to work well in practice. Similarly, instead of
supporting the upper end of the lever between two springs, the lever may be con-
trolled by one spring, and all these matters of detail may be varied to suit the
requirements of the machinery to be lubricated in any particular case without
affecting the essence of my invention.
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:
