I, ARCHIBALD CLARK, of Cowgate Street, Kirkintilloch, N.B., Carrier, do hereby
declare the nature of this invention to be as follows:-
This invention relates to improved means for lubricating railway waggon axles,
also applicable for lorries, carriages, and other vehicles.
I employ a circular metal dise provided with a screwed tail piece which is screwed
into an opening provided at any convenient position on the front of the ordinary
axle box. The said screwed tail piece is formed hollow or provided with a channel
and has an opening formed at the side by cutting away a part of the screwed
portion, the arrangement being such that when the tail piece has been partially
screwed out of the opening in the front of the axle box, the side opening on the
tail piece is exposed so that oil can be poured therein and led from thence by the
channel into the box. After oiling, the tail piece is again screwed into the opening;
the disc, which may be provided with a circular recess for the reception of a rubber,
leather or other washer, thereby covering the opening and forming a tight joint.
The disc may also be provided with a thumb piece for screwing and unscrewing
it and in order to prevent the tail piece from being entirely withdrawn from the
opening I may provide the end thereof with a number of saw cuts or slits so that
the edges can be splayed out or I may employ any other suitable means for the same
purpose.
If desired the opening in the axle box may be situated at the side thereof in place
of in front.
When applying my invention for lubricating the axles of lorries, carriages and other
vehicles I provide the cup, which is screwed upon the bush of the wheel, with the
screwed opening and insert the tail piece therein, the disc in this case however being
preferably formed with a milled edge for screwing and unscrewing it in place of the
thumb piece first described.

I, ARCHIBALD CLARK, of Cowgate Street, Kirkintilloch, N.B., Carrier, 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 improved means for lubricating railway waggon axles,
also applicable for lorries, carriages and other vehicles.
I employ a circular metal disc provided with a screwed tail piece which is screwed
into an opening provided at any convenient position on the front of the ordinary axle
box. The said screwed tail piece is formed hollow or provided with a channel and has
an opening formed at the side by cutting away a part of the screwed portion, the
arrangement being such that when the tail piece has been partially screwed out of
the opening in the front of the axle box the side opening on the tail piece is exposed
so that oil can be poured therein and led from thence by the channel into the box.
After oiling, the tail piece is again screwed into the opening; the disc, which may
be provided with a circular recess for the reception of a rubber, leather or other
washer, thereby covering the opening and forming a tight joint.
The disc may also be provided with a thumb piece for screwing and unscrewing
it and in order to prevent the tail piece from being entirely withdrawn from the
opening I may provide the end thereof with a number of saw cuts or slits so that
the edges can be splayed out or may employ any other suitable means for the same
purpose.
If desired, the opening in the axle box inay be situated at the side thereof in place
of in front.
When applying my invention for lubricating the axles of lorries, carriages and
other vehicles I provide the cup which is screwed upon the bush of the wheel with
the screwed opening and insert the tail piece therein, the disc in this case however
being preferably formed with a milled edge for screwing and unscrewing it in place
of the thumb piece first described.
In the accompanying explanatory sheet of drawings
Fig. 1 is a sectional elevation
Fig. 2 a sectional plan and
Fig. 3 a front view shewing my improvements applied to the axle cup of a
carriage.
Fig. 4 is a plan of same shewing the parts in position ready to receive the
lubricant.
Referring to the said drawings, A is the screwed tail piece secured to or formed
as part of the milled disc B and having the opening or aperture C in the side
thereof, D is the washer preferably partly sunk in the disc B.
Figs. 1, 2 and 3 shew the tube or tail piece screwed into the cup, the disc being
retained in this position and prevented from working loose by a small spring catch E
of steel or other metal provided with a pin or projection e which engages with
corresponding holes or recesses e¹ in the cup; the said pin or projection being
disengaged by actuating the catch, which preferably projects slightly beyond the rim
or edge of the disc to enable it to be readily found by touch.
When it is desired to use grease as the lubricant the disc and tail piece may be
entirely removed from the axle box or cup, the grease being then inserted through
the circular aperture and the disc replaced.
Also if desired, the tail piece may be provided with one or more saw cuts f to

page_text: enable a portion thereof to be "turned up "to prevent its being completely withdrawn
from the cup.
A great advantage derived from my invention is that the improvements can be
applied to existing cups with little trouble and expense and that the general
appearance is not to any appreciable degree detracted from as has been more or less
the case with the cups as hitherto constructed with this object.
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 improved means for lubricating railway waggon axles, also applicable for
lorries, carriages and other vehicles, substantially as hereinbefore described and
shewn in the accompanying drawings.
2. In means for lubricating railway waggon axles, also applicable for lorries,
carriages and other vehicles, the circular disc B having the screwed hollow tail
piece A capable of being screwed into or out of the axle box or cup and provided
at the side with the opening or aperture C whereby the lubricant is quickly and
easily applied to the axle, substantially as herein before described and shewn in the
accompanying drawings.
