I GEORGE JACKSON CHURCHWARD of 13 Glo'ster Terrace, Swindon in the County
of Wilts Engineer, do hereby declare the nature of my Invention for IMPROVE-
MENTS IN THE MEANS OF LUBRICATING THE AXLES OF RAILWAY LOCOMOTIVES
AND VEHICLES to be as follows:-
My Invention has relation to the means of applying oil to the bearings of
Railway Locomotives and Vehicles-For this purpose I use a combination of
curled horse hair with cotton and woollen threads or "waste"-This I employ
instead of the usual steel spring and woollen pad; or of cotton and woollen
"waste," as sometimes used,

page_text: I, GEORGE JACKSON CHURCHWARD Engincer, 13 Gloster Terrace, Swindon in
the County of Wilts do hereby declare the nature of my invention for IMPROVE-
MENTS IN THE MEANS OF LUBRICATING THE AXLES OF RAILWAY LOCOMOTIVES
AND VEHICLES, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
My invention relates to the means of applying oil to the axle bearings of
Railway Locomotives and Vehicles.
For this purpose I employ a combination of horse hair with cotton or woollen
threads or "
waste" in place of the usual woollen pad and spring or counterweight,
or in place of "waste" only as used in some axle boxes.
My combined material is made by combing or "carding" the horse hair and
threads intimately together.
In the combination material the cotton or woollen threads serve to take up the
oil and distribute it on the bearing whilst the horse hair acts as a spring to keep
the threads in close contact with it, and at the same time to keep the texture of
the material sufficiently open to admit of the deposit of any grit or dirt on the
bottom of the axle box. The horse hair in the combination also prevents the
'clogging" which results in the usual pad or "waste."
"
My combined material is particularly adapted for use in the various kinds of
axle boxes constructed for lubrication by means of spring pads or " waste."
In these cases I remove the pads and springs and fill the bottom parts of the
axle boxes tightly with the. combined material, feeding the oil to the boxes in
the same manner as previously adopted for the pads.
I sometimes convert the usual open bottom grease axle boxes for the use of oil
by fitting to them a tray or reservoir filled with my combined material instead of
the ordinary bottom "keep."
For Locomotives I employ a tray or reservoir filled with my combined material
instead of the usual bottom "keep," retaining the ordinary means of feeding the
oil on the tops of the axle boxes.
I sometimes weave the horse hair and cotton or woollen threads into the form
of a pad and apply the oil to it by means of the usual "oiling wicks," keeping the
pad in contact with the bearing by a spring.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is
"waste" as
The combination of horse hair with cotton or woollen threads or
a material for applying oil to the axle bearings of Railway Locomotives and
Vehicles.
