PROVISIONAL SPECIFICATION.
Improvements in Axles and Lubricators therefor.
We, GEORGE WELLINGTON BUTLER, of Ridgetown, DANIEL CAMERON, JOHN
FRANKLIN LOUCKS, RICHARD CAMERON, and HART CAMERON, of Palmyra, Ontario,
Canada, Farmers, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide means whereby the lubricant applied
to axles is enabled to find its way more readily from the lubricator, situated at
one end of the axle, to the other end. A further object is to provide a lubricator
of improved construction which will be readily accessible and particularly
adapted for use in connection with axles made according to our improvements.
By this invention, the axle is grooved longitudinally; the groove being deeper
at its inner than at its outer end. Vertical perforations extend at intervals
'rom the groove to the underside of the axle to permit the lubricant entering the
groove to quickly pass to the bearing or box of the wheel.
A collar is situated at the inner end of the axle against a shoulder and has a
perforation coincident with the groove. A lubricator is recessed in the upper
face of the bolster and has the opening in its lower end coincident with the
perforation in the collar. The lubricator is provided with a lid which is hinged
and kept normally closed by means of a spring in such manner that it will remain
either open or closed; the perforated lugs on the lid through which the hinge-
pin passes being angular and having one flat surface bearing upon a flat spring,
Secured to the bolster, when the lid is open, and another surface bearing on the
spring when the lid is closed.

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :---

Reference being had to the accompanying drawings:
Figure 1 is a perspective view, partly broken away, illustrating one end of
an axle equipped with my improvement. Fig. 2 is a longitudinal central section
and detail views of the same. Figs. 3 and 4 are transverse sections taken on
the planes indicated by the broken lines - and y-y respectively, of Fig. 2.
In the said drawings similar numerals designate corresponding parts in all the
several views.
The axle-bar supports the wooden bolster-bar 1 to which it is suitably con-
nected and has the usual spindle 2 and collar 3, the spindle being provided with
a longitudinal groove 4 and the collar with an aperture 5 connected with the
groove as shewn on the axle-bar. At one end of the bolster-bar is arranged
an improved oil-cup 6 which is preferably cast or otherwise formed in one piece.
This cup has a nipple 7 arranged in the aperture 5 of the collar so as to feed
the lubricant to the groove in the spindle, and it is also provided at its inner end
with the extended horizontal part 8 and vertical walls 9 which are designed to
receive between them the reduced end of the bolster-bar to which the cup is
connected by screws 10 passed through the walls 9 as best shewn in Fig. 4.
The entire upper side of the oil cup is arranged in. the same horizontal plane
as the upper surface of the part 8 in order to afford a flat seat for a cover 11
which has for its purpose to tightly close the cup and thereby exclude grit,
dust etc. from the interior thereof. The cover is of a shape and size to entirely
rest over the top of the cup and the extended part 8 thereof and is provided in
its inner end with a bifurcation 12 across which extends the angular hinge-pin 13
secured in lugs on the side walls 8.
A spring 14 is provided, and, in addition to connecting the cover 11 with the
bolster-bar 1 serves to keep the cover closed over the cup to effectually exclude
foreign matter from the interior of said cup and yet permit the cover to be
conveniently raised when it is necessary to charge the cup with lubricant. Inas-
much as the spring rests upon either one of two of the flat surfaces of the angular
hinge-pin it will be understood that the lid will remain either open or closed.
The spring is connected at one end to the upper side of the bolster-bar as
shewn.
In order that the lubricant may pass from the groove 4 ducts 16 may be madè
through the axle; the inner ducts being smaller than the outer ones to prevent
the whole of the lubricant from passing through the first duct to the underside
of the axle. If preferred, grooves 15 of gradually increasing depth may extend
from both sides of the groove 4 around the outer surface of the axle, and the
ducts be dispensed with.
It will be understood from the foregoing that our improved lubricator embodies
but a minimum number of parts which are not likely to get out of order in
use and that it is adapted to be quickly and easily secured in its operative position
on an axle.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
(1) The hereindescribed improvements in axles, consisting of the formation of
a longitudinal groove therein and ducts or grooves extending transversely through
or radially around the axle from the bottom or opposite sides of the longitudinal
groove to the under side of the axle, and a recess in the bolster to receive a
lubricator communicating with the aforesaid longitudinal groove by means of
an aperture in a ring on the spindle substantially as and for the purposes herein-
before set forth, and illustrated in the drawings hereunto annexed.
(2) The hereindescribed improvements in axles and lubricators therefor, said

page_text: improvements consisting in the formation of a longitudinal groove in said axle,
ducts or grooves extending transversely through or radially around said axle
from the bottom or opposite sides of the longitudinal groove to the underside of
the axle, a bolster which has its ends recessed to receive a lubricator super-
imposed upon the axle and the lubricator consisting of a suitably shaped re-
ceptacle having extended sides to embrace the bolster and be secured thereto by
screws, a lid or cover hinged to the receptacle and adapted to be retained either
open or closed by means of a spring, all substantially as and for the purposes
hereinbefore set forth, and illustrated in the drawings hereunto annexed.
