Improvements in Lubricators.
1, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
Southampton Buildings, in the county of Middlesex, 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 relates to gravity-feed lubricators, which are employed for automati-
cally oiling journals and other similar bearings and consists-First, in a novel
construction of loosely-coupled valve for regulating the discharge from the fount or
reservoir. Secondly, in providing the reservoir with two or more laterally-adjustable
nozzles, which can be shifted either toward or away from said reservoir as occasion
requires, so as to accommodate themselves to a set of oil holes in the cap of a journal
box or other bearing. Thirdly, in rendering the sight chambers of these nozzles
vertically adjustable, for the purpose of being more readily applied to certain forms
of journal boxes or other bearings. Fourthly, in a novel cut-off for simultaneously
closing the channels leading from the oil-reservoir to the upper and lower sockets that
contain the ends of the glass-gage or index usually applied to gravity-feed lubricators,
and, Fifthly, in a novel combination of devices for securing detachable glasses to the
sight-chamber of the lubricator, all as hereinafter describo.
In the accompanying drawing,
Figure 1 is a side elevation of a lubricator provided with three discharge-nozzles,
the central nozzle being shown in operation, while the two side nozzles are
inoperative, the sight chamber of one of said nozzles being shown in section.
Figure 2 is an enlarged section through the valve-operating devices, the valve
proper being raised from its seat.
Figure 3 is an enlarged vertical section of the duplex cut-off, for the glass gage or
index of the lubricator.
Figure 4 is an enlarged horizontal section through the sight chamber and its
accessories.
Figure 5 is a sectional elevation of a portion of one of the laterally adjustable
nozzles.
Figure 6 is an enlarged section of the valve-carrier and its adjuncts, and,
Figure 7 is a modification of the invention.
The fount or reservoir A, which is usually a hollow metallic cylinder, has a pair of
integral sockets B, B1 to admit the ends of the glass gage or index C, which tube is
retained within said sockets by a customary screw-cap c. Furthermore these sockets
have channels b, b₁ communicating with the interior of the reservoir, as seen in
figure 3, and the said channels are controlled by conical turning-plugs D, DI, provided
with transverse ports d, d' and the plug D having in its lower end a square mortise ("
to receive a square tenon d, at the upper end of a stem. The stem a projects
rigidly from the lower plug D1, which latter is retained within its conical scat by a
washer and nut-connection E. E¹ is a plate that retains the plug within its seat,
said plate being pierced centrally to permit free turning of the square e at the upper
end of said plug. Fount A has on its upper head an interiorly-threaded neck a to
admit a long tubular nut F having a smooth bore f that permits freo play of the
stem G around which latter is coiled a pushing spring g, whose upper end bears
gainst the nut F, as seen in figure 2. is a jam nut that holds the nut F to any
specific adjustment, for the purpose of imparting more or less tension to the spring
and, on this account, said device F will hereinafter be alluded to as the "tension nut.

page_text: The lower end of spring g bears against the cylindrical valve carrier H, having a
chamber h, and at bottom a screw-threaded cap I, provided with a bore i, so enlarged
as to permit a slight lateral play of a short plug J, terminating with a conical
portion that constitutes the valve proper of the lubricator. Plug J has at its upper
end a fixed collar K, that normally rests upon the cap I, said collar being held in this
position by a spring k, coiled around the shank A, of the plug, (See Figure 6). Lis
a forked lever or handle pivoted to the upper end of stem G, which lever is capable
of being swung either up or down, as occasion requires. Valve carrier H is confined
to a vertical path by a short open mouthed cup N at the bottom of the fount and
and a
usually integral therewith, said cup being provided with one or more inlets
valve seat n, which seat is located at the upper end of a channel o, traversing the
discharge nozzle 0. This nozzle projects down a sufficient distance into the sight
chamber P, which chamber is formed in the base or standard 2 of the lubricator and
said base is, in many cases, integral with the fount. pl is the screw connection where-
with the base is attached to the cap of a journal-box or other bearing. The sides of
base have horizontal flanges 7, q' between which are inserted glasses Q, Q', the
latter being held in place by clips R, R', whose ends r, are so bent as to grasp the
vertical edges of said glasses, as more clearly seen in figure 4. are screws where-
with the clips are secured to the ends of the base p, and, if desired, these screws may
have milled heads, so as to be readily turned by hand. Projecting horizontally from
the fount A, and near the bottom of the same are laterally adjustable side-pipes S, S',
traversing stuffing boxes s, t, and communicating with chambers T, T', from which
depend discharge nozzles t, t¹, said chambers being provided with valve operating-
devices precisely similar to those seen in figures 2 and 6. It is preferred, however, to
apply a packing ring to the upper end of valve-carrier H, as seen at H¹, in figure 5,
which packing prevents oil ascending within the chamber T. Each side pipe is
slotted longitudinally at 1, to admit the point of a screws, which screw prevents
said pipe turning. Furthermore, this screw serves as a stop to prevent the pipe
U is
being pulled out, by coming in contact with the inner or closed end of said slot.
a nipple into which the shank pl of the base p may be screwed the said nipple being
engaged with the cap V, of a journal box or other similar bearing. This cap has
three channels v, v, vl, for the passage of oil down to the journal. 10, w, and w³, wo¹,
are perforated lugs projecting from the sockets B, B1 and traversed by readily-
removable rods, W, W, which serve as fenders or guards to prevent the tube C being
injured. The swinging scutcheon a', seen only in figure 1, covers the filling hole of
the reservoir.
When this lubricator is to be fitted to a long journal-box cap or other bearing having
three oil holes t, v, l, the axial nozzle is inserted within the central hole v¹ and
the side pipes S, S', are then adjusted laterally, so as to allow their respective
nozzles t, to communicate with the other holes v, 1, as seen in figure 1. The
handle L is then swung up to a vertical position and the tension nut is adjusted
until a sufficient opening is left between the valve j and seat n¹, to afford the desired
discharge of oil, after which act, the jam nut f¹ is tightened to preserve this adjust-
ment and prevent it being disarranged by the vibrations of the machinery or
otherwise. The various valves having been thus adjusted, the oil is delivered from the
nozzles Ot, t, and passes down through the channels e, v¹, ¹¹, to the journal the feed
or rate of delivery being plainly seen at the windows Q, Q. Furthermore, as this
feed can take place only when the handles L are elevated, it is evident they act as
signals to indicate the proper working of the lubricator. The feed can be stopped
from either or all the nozzles by simply swinging the handles down, as seen at L
and I, in figure 1, thereby closing the valves, (See Figure 5). While thus swinging
down the handle, the spring g has an opportunity to exert its full force which act
would jam the valve j violently against its seat, in case said valve were rigidly
attached to the stem G. But as it is yieldingly coupled thereto by the spring k, the
valve j, accordingly closes without any jar or concussion,.and on this account, neither
the valve nor seat can be injured, no matter how suddenly the lever may be thrown

page_text: down. Furthermore, as the plug J, has sufficient lateral play within the bore i of
cap f, the valve j can automatically adjust itself to the seat while closing, although.
the latter may not be accurately in line with the operating stem G. When the valves
are closed, the turned down or horizontal handles indicate that the lubricator is
inoperative, for the time being. If either of the glasses Q or Q', should break, one
of the screws can be slackened sufficiently to permit such a shifting of the clip R
or R, as will enable the broken glass to be taken out. A new one can then be
inserted in a few moments and secured in place by again tightening up said screw,
which operations can be performed without removing the lubricator or stopping the
engine or machinery. Neither is it necessary to stop the flow of oil while these
repairs are being made.
If the index tube C, should break, the plugs D, D' can be simultaneously turned,
so as to close the passages b, & leading to said tube, and then the cap c can be
unscrewed to facilitate the removal of the old tube, and the insertion of a new one.
After the new tube has been applied, and the cap screwed to the socket B, the
plugs D, D' are turned to open communication between said tube and the oil reservoir,
which changes can be effected without disturbing any of the other attachments of the
lubricator, or stopping the flow of oil through the sight chambers or chamber.
the modification of my invention, seen in Figure 7, the side pipe X is screw-threaded
externally, so as to be adjusted out or in with reference to the reservoir A, and the
pendant tube Y is screw-threaded at its lower end, as at y. Z is a nozzle engaged
with this screw-threaded tube. By this arrangement the nozzle can be adjusted
either up or down, as occasion requires, thereby dispensing with the nipple U, seen in
Figure 1.
