Improvements in Lubricators.
A communication from CARL ANDERSSON and TAGE BLOм, of Nordvestvej 13,
Copenhagen, in the Kingdom of Denmark, Manufacturers.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E., do hereby declare the nature of this invention and in what manner the same
s to be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to an automatic and adjustable lubricator for axle bearings
and the like, arranged in such a manner as simultaneously to supply oil to the various
parts of the bearing, the oil-supply being controllable and capable of being
proportioned to the requirements of each particular bearing.
In the accompanying drawings ;-
Fig. 1 is a longitudinal section of the lubricator, Fig. 2 is a cross section thereof,
Fig. 3 is a detail view of a modification of a similar device and Figs. 4 and 5
are cross sections of such modification.
g
The lubricator consists of a chamber or reservoir A at the bottom of which a barrel c
is formed through which a longitudinal opening is bored for the reception of a spindle
or plug D; there are also a number of radial openings in which tubes E are fitted.
Each tube E communicates through a socket P with a lubricating tube a leading to
the axle bearing; and is also connected with an air pipe K the top of which should
always emerge from, or rise above the level of the oil contained in reservoir A.
Corresponding to the tube-holes E provided in the barrel, a number of diametrical
apertures are formed in spindle or plug D, which however do not traverse such plug
or spindle entirely. These apertures are provided with screw threads so as to fit
screwed plugs F the position of which in their respective apertures determines the
quantity of oil supplied to the different bearings at the time.
Spindle or plug D is connected with the machine, and revolves with the same.
When the reservoir is filled with oil, the latter enters openings H and if spindle D is
in the position shown in figs. 1 and 2 its own apertures are filled with oil at the same
time. Upon turning the said spindle or plug D this oil is discharged into the tube-
holes E whence it passes to the bearings it is desired to lubricate.
Instead of a round and revolving spindle, a rectangular plug or plunger D
figs. 3, 4 and 5 may be employed, to which is imparted a reciprocating motion, and
which may be connected with the machine by means of an eccentric, cam or other
gear. The openings in plug D corresponding to tubes E are in the latter case bored
entirely through the said plug, and instead of the plugs F screws are used, which,
according as they are screwed in or out increase or reduce the space available for oil
within the said openings.
Also the air pipes K need not necessarily be bent at right angles as shown in fig. 2,
but may form continuation sof tubes: E immediately above plug D figs. 4 and 5. In
the barrel-part cone aperture is provided between each successive pair of tubes E
both in the portion situated above the plug D and in that which is below the same.
The oil enters these apertures and when plug D is caused to assume such a position
that each tube K with the corresponding opening in plug D and a tube E forms one
continuous conduit such oil is carried by the latter to the bearing it is desired to
lubricate. In fig. 4 the lubricator is shown at the moment when the oil enters the
apertures d of plug D but before it is allowed to proceed to the bearings; while Fig. 5
shows the three tubes above referred to connected into one, whereby the oil is
permitted to flow from orifices d to the bearings it is required to lubricate.

Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondents, I declare that what I claim is ;-
1. A lubricator characterized by a chamber or reservoir such as A provided with a
barrel part e, tubes E. and K and a revolving plug or spindle such as D having
apertures in it the capacity of which can be regulated by adjustable plugs the whole
constructed and operating substantially as described and illustrated in the accom-
panying drawings.
2. In a lubricator the employment of a reciprocating plug or plunger such as D
provided with orifices the capacity whereof may be extended or reduced by means of
adjusting screw F substantially as and for the purpose described and illustrated in the
accompanying drawings.
:
3. The combination and arrangement of parts forming the complete lubricator
substantially as described and illustrated in figs. 1 and 2 of the accompanying
drawings.
4. The combination and arrangement of parts forming the complete lubricator
substantially as described and illustrated in figures 3 to 5 of the accompanying
drawings.
