Midlothian, Engineer, do hereby declare the nature of this invention to be-as
follows:-
:-
My invention relates to apparatus for applying grease or other lubricant to the
axle journals of coal hutches or wagons the improvements having for object the
construction of such apparatus in an extremely simple form and at low cost,
The improved apparatus comprises a tank or box of cast iron or steel, or built up
of sheets or plates and adapted to contain the lubricant. Within the tank two
dises or wheels having plain tyres of metal are carried upon a spindle or axle
which, for lightness, is by preference formed from a metal tube whose ends are cast
into the discs or wheels, said wheels being at a distance apart corresponding to the
gauge of the hutch axle journals. The axle is supported in bearings near each end.
upon springs which may be in the form of inverted carriage springs or blades
extending across the tank and carried upon brackets on the sides or floor of the
tank; or the axle may be supported in bearings upon cross bars which bear at each
end upon helical or other springs fitted within cups or around bolts projecting.
vertically upwards from the bottom of the tank. The tank is filled or partially
filled with the lubricant so that the rims or tyres of the discs or wheels which
project upwards over the top of the tank or through orifices, formed in a cover
placed thereon are immersed in the lubricant; and the tauk is sunk between the
hutch trams or rails to such an extent that the hutch axle journals come in contact
with the upper edges of the disc or wheel rims in passing over the apparatus and
slightly depress the discs, the springs permitting of the necessary yielding inove-
ment. The frictional contact of the discs with the axle journals passing over them
causes a partial rotation of said discs whereby a quantity of the lubricant is brought:
up to be applied by the rims of the discs to the axle journals of the next hutch
passing over the apparatus, the lubricant employed being of such a consistency as
to spread itself over the bottom of the tank as it is withdrawn therefrom while it
is sufficiently viscous to adhere to the plain rims or tyres of the discs or wheels
which feed the lubricant to the axle journals of the hutches.

I, ROBERT ARMSTRONG of Lingerwood House, Lasswade, in the County of
Midlothian, Engineer, 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:-
--
My invention relates to apparatus for applying grease or other lubricant to the
axle journals of coal hutches or wagons the improvements having for object the
construction of such apparatus in an extremely simple form and at low cost.
The accompanying drawings represent the improved hutch axle lubricating
apparatus in sectional elevation at figure 1, in plan with cover removed in figure 2,
in plan as covered in figure 3 and in cross section at figure 4.
The improved apparatus comprises a tank or box A of cast iron or steel or
built up of sheets or plates and adapted to contain the lubricant. Within the tank
two discs or wheels B, B having plain tyres of metal are carried upon a spindle or
axle C which for lightness is by preference formed from a metal tube whose ends
are cast into the discs or wheels B, B, said wheels being at a distance apart corre-
sponding to the gauge of the hutch axle journals. The axle C is supported in
bearings D near each end upon springs E which may be as shown in the form of
inverted carriage springs or blades extending across the tank and carried by rods
or bars F fitted in brackets G on the sides or floor of the tank; or the axle may
be supported in bearings upon cross bars which bear at each end upon helical or
other springs fitted within cups or around bolts projecting vertically upwards from
the bottom of the tank. The tank A is filled or partially filled with the lubricant
so that the rims or tyres of the discs or wheels B, B, which project upwards over
the top of the tank or through orifices formed in a cover A¹ placed thereon are
immersed in the lubricant; and the tank is sunk between the hutch trams or rails
to such an extent that the hutch axle journals come in contact with the upper
edges of the disc or wheel rims in passing over the apparatus and slightly depress
the discs B, the springs E permitting of the necessary yielding movement. The
frictional contact of the discs B, B, with the axle journals passing over them
causes a partial rotation of said discs whereby a quantity of the lubricant is brought
up to be applied by the rims of the discs to the axle journals of the next hutch
passing over the apparatus, the lubricant employed being of such a consistency
as to spread itself over the bottom of the tank as it is withdrawn therefrom while
it is sufficiently viscous to adhere to the plain rims or tyres of the discs or wheels
which feed the lubricant to the axle journals of the hutches.

page_text: 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 :-
1. The combination of parts constituting the improved hutch axle lubricating
apparatus herein described with reference to the drawings.
2. In hutch axle lubricating apparatus the discs or wheels carried upon springs
and having plain rims or tyres for applying the lubricant to the axle journals
of the hutches substantially as herein described with reference to the annexed
drawings.
