Improvements in Axle Lubricators.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co., Patent Agents,
45, 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 improvements in car-axle lubricators in which a block
of felting or wicking operates in conjunction with a chair or support having
journal bearings at one end, in which oscillates a journaled receptacle containing
felting or wicking for the purpose of lubricating car-axles; and the objects of
these improvements are, first, to provide a sure and simple method of oiling car-
axles; second, to assure a perfectly lubricated bearing; third, to prevent the
heating of the journals as heretofore. These objects are attained by the
mechanism illustrated in the accompanying drawings, in which
Figure 1 is a isometrical view of the lubricator in position in the box or
housing.
Figure 2 is a partial longitudinal cross-section of the lubricator and housing
through the centre.
Similar letters refer to similar parts through the several views.
The weight C, its support F, and the case or receptacle E constitutes the frame-
work for the lubricator. The support F has a fulcrum point d adapted to rest
on the bottom of an ordinary car-axle box or housing near the centre of its entire
length and at the lower extremity of the said support F are two bearings or
apertures on either side thereof which serve to hold the felting D contained in
the receptacle E, through the medium of the projecting pins in contact with the
axle; and allowing it to keep an equal bearing on the journal B in spite of any
oscillations thereof, the fulcrum point d moving freely on the curved bottom of the
axle box and taking up any wear that may be caused by the journal B or irregular
wearing of the same, the bottom of the said receptacle E being on a circle to
allow this adjustment, and, also to allow the felting to come down to the bottom
of the receptacle E and to nearly touch the bottom of the box or housing A.
The other end of the said support F is supplied with a weight of the proper size
to hold the felting or wicking D in contact with the journal B the fulcrum-
point being of the required height to allow this adjustment. The casting or
support F is also provided with projections a, a nearly touching the housing on its
side to keep the lubricator within proper bounds within the housing A, and also to
prevent any displacement of the same when on the road. The fulcrum-point could
be in any place on the lower part of the casting or support F. For instance, it
could be nearer the lugs on the end of the casting F and allow a smaller weight C
to hold the felting D in contact with the journal B.
The lower part of the receptacle E could be of any shape if it was made to
come down and nearly come in contact with the lower part of the housing A
and thereby taking the oil from the bottom of the housing and depositing it on
the journal B, as the felting is always saturated with oil as long as any oil
remains in the box or housing, and thereby assuring a perfectly lubricated
bearing.
Lubricators employing felting or wicking are well known and this use broadly
considered is not this invention.

page_text: 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 correspondent, I declare that what I claim is :-
First. A car-axle lubricator provided with a casing or a receptacle E for the
purpose of containing the felting or wicking D, and the said receptacle provided
with journals-on-opposite sides adapted to oscillate in the bearings secured to one
end of the casting or support F to allow a vertical movement of the aforesaid
receptacle, and also to allow the felting or wicking to keep an equal bearing on
the journal, as set forth and described.
Second. A car-axle lubricator provided with a casting or support F having a
fulcrum-point d adapted to rest on the bottom of the box or housing A, the afore-
said support supplied with a weight C of the proper size to hold the felting or
wicking in contact with the journal and to take up any wear in the journal B or
the felting D, as herein set forth and described.
