PROVISIONAL SPECIFICATION.
An Improved Lubricator and Bracket for Axle Bearings.
WILLIAM DENNIS HODGKINSON Newthorpe Nottinghamshire Coal Miner and
Ironmonger, do hereby declare the nature of this invention to be as follows:-
+
This bracket, which may be capped or otherwise, receives the axle, and is made
with a recess to receive the lubricator, which is fitted into the said recess in the
form of a drawer in which manner it is operated on. In the bottom of the
lubricator is a hole, immediately over that in the bracket, through which
the lubricant passes to the bearings. To hold the lubricator in its position in the
recess of bracket a latch or catch with a spring is provided. This spring also
governs the drawer or vessel containing the lubricant in whatever position it may
be while in the bracket. The vessel or drawer is provided with a lid or cover,
which is operated on by the above spring latch, or catch, which closes the lid or
cover when the vessel or drawer is pushed into its position in the recess, holds the
lid or cover in the same position while in the recess, opens it by pressing upon its
back part when the vessel or drawer is released, and also prevents the vessel or
drawer from being forced too far out, unless desired, in which case the lid or cover
is closed, thus raising the spring, and permitting the drawer or vessel to be totally
withdrawn. To assist the outward movement of the vessel or drawer a spring is
inserted between the back of the drawer and the back of the recess. The lid
which is moveable is supported on either side of the vessel or drawer by. &
projection.

COMPLETE SPECIFICATION.
An Improved Lubricator and Bracket for Axle Bearings.
I, WILLIAM DENNIS HODGKINSON, of Newthorpe, in the County of Nottingham,
Coal Miner and Ironmonger, 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 an improved lubricator and bearing bracket: for axles.
In carrying out my invention I form the bearing bracket (which may be capped
to exclude dust from the bearing) with a recess to receive the lubricator which is
advantageously in the form of a drawer. In the bottom of the lubricator is a
hole which, when the drawer is closed, will be immediately over a hole in the
bracket so that the lubricant can pass to the bearing. The lubricator is held" in
the closed position by a spring arrangement; such spring arrangement also serving
in some cases to govern the movement of the lubricator. When used for liquid
lubricants the drawer is provided with a hinged lid or cover operated by the spring
arrangement which, when the drawer is drawn out of the recess, holds the lid' or
cover in the open position and prevents the drawer being drawn out too far."
1 1
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawings, in which
Figure 1 is a front elevation of my improved lubricator and bearing bracket' for
axles and a portion of the framing of a waggon to which it is attached:

Figure 2 is a plan with the said framing removed :
Figure 3 is a section on the line 3-3, Figure 1; and,
Figure 4 is a similar view to Figure 3 shewing the lubricator in position for
receiving a supply of lubricant:
Figure 5 is a similar view to Figure 2 illustrating a modification; and,
Figure 6 is a section on the line 6-6, Figure 5, but shewing the lubricator
attached to the waggon framing.

is my
a is the bearing bracket connected to the waggon frame a¹ by bolts a³, a³, the
said bracket being advantageously provided with a cap b to exclude dust from
the bearing c.
d is the recess which I make in the bracket a, and
lubricator in the form of a drawer adapted to be moved in the said recess and
kept in its closed position therein by the spring f fixed at one end to a flange a
in the bracket a, as shewn clearly in Figure 3; g is the hole in the bottom of the
lubricator, and the hole in the bracket a through which the lubricant passes to
the bearing c when the drawer is in the closed position shewn in the said figure.
i is a screw which where a liquid lubricant is employed I find advantageous to
use in the hole for preventing a too rapid flow of lubricant to the bearing, the
said screw being, supported on the axle. so that if the latter be removed from
the bearing for any reason the screw will fall and its head will bed itself in the
countersink of the hole h and prevent further flow of lubricant.
kis the lid or cover which I employ when the lubricator is used to contain
liquid lubricant, the said lid being hinged as at 1, 1 and connected to one end of the
spring so that when the drawer is drawn out of the recess d into the position
shewn in Figure 4 the spring will cause the lid to open and hold the drawer
in its open position when it can be supplied with lubricant, the lid bearing by
the tension of the spring against the front of the frame a¹. By moving down
the lid k by hand or. by applying pressure to the front of the drawer, the spring f
will return the drawer to its normal position in the recess d so as to bring the
holes g and into coincidence for the lubricant to pass to the bearing.
The
movement of the drawer is such that when drawn out the hole g is still within
the recess das indicated in Figure 4, thus preventing any escape of lubricant
through the said hole.
I
When adapting my lubricator for use with solid lubricants, such as grease,
dispense with the lid k and back portion of the drawer e as shewn in Figures 5
and 6 and connect the spring directly to the front e¹ of the said drawer whereby
the said front will under the tension of the spring he moved into the recess d and
continually exert pressure upon the lubricant and force it through the hole h into
the bearing c. To prevent any leakage round the front of the drawer during its
action 1 advantageously provide a lining m of leather or other suitable material on
the walls of the recess d.
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 :-
1. The combination of an axle bearing bracket provided with a recess having
a lubricating hole extending to the bearing and a drawer for containing the liquid
lubricant adapted to slide in the said recess, the said drawer also having a
lubricating hole which when the drawer is closed coincides with the lubricating
hole in the bracket substantially as, and for the purpose, described.
2. In a bracket having a lubricator drawer as described, connecting the drawer
to the bracket by a spring in such a manner that when the drawer is drawn out
the lid of the drawer is caused to open and hold the drawer in such position but
when the lid is closed the drawer is drawn back into the recess whereby the
lubricating hole in the said drawer comes into coincidence with the lubricating
hole in the bracket substantially as described and illustrated in Figures 1 to 4
of the accompanying drawings.
3. The combination with an axle bearing bracket provided with a recess having

page_text: a lubricating hole extending to the bearing of a front plate connected by a spring
to the said bracket in such a manner that it is caused by the tension of the spring
to press a solid lubricant through the said lubricating hole into the bearing,
substantially as herein before described and illustrated in the Figures 5 and 6 of
the accompanying drawings.
4. The improved lubricators and brackets for axle bearings hereinbefore
described and illustrated in Figures 1 to 4, and 5 and 6 of the accompanying
drawings.
