I THOMAS HENRY RAMSDEN of Bramhope, near Leeds, in the county of York land
agent, do hereby declare the nature of this invention to be as follows:-
On or near the outer edge, or front rim of a lubricating cup or axle box for a road
vehicle I provide a hole for a lubricating passage. The said cup or box is made with
a little more substance where the hole is wanted. The hole is countersunk, and
tapped. A suitable screw is made for the said hole. The head of the screw may have
a thread, and the circumference of the countersinking may be tapped to correspond
therewith. The seat of the countersinking, and the under surface of the screw head
may be roughed to keep the said screw in position. A washer of softer material than
the said axlebox is put on the said screw. The said hole, the said screw, and the said
washer may be in connection with an axle box, or lubricating cup screwed on the
nave of a wheel; or in connection with one fastened to the nave by bolts.

Vehicles.
I THOMAS HENRY RAMSDEN, of Bramhope near Leeds in the county of York land
agent 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.
On or
near the edge or front rim of a lubricating cup or axle box for a
road vehicle I provide a hole for a lubricating passage. The said cup, or box
is made with a little more substance where the hole is wanted. The hole is
countersunk and tapped. A suitable screw is made for the said hole. The
head of the screw may have a thread, and the circumference of the countersinking
may be tapped to correspond therewith. The seat of the countersinking, and the
under surface of the screwhead may be roughed to keep the said screw in position. A
washer of softer material than the said axle box is put on the said screw.
The said
hole, the said screw, and the said washer may be in connection with an axlebox or
lubricating cup screwed on the nave of a wheel, or in connection with one fastened to
the nave by bolts.
The improvements in axleboxes and lubricating cups of road vehicles are illustrated
in the accompanying drawing.
Figure 1 shews a side elevation of an axlebox for a wheel of a road vehicle; and
figure 2 shews a section enlarged of part of the said axle hox.
b
Like letters refer to like parts in the drawing. The axle box or lubricating cup of
a road vehicle is marked a; and b is the hole or lubricating passage inserted at or on
the front rim of the axle box a, although if more convenient the said passage 6 may be
inserted on either side of and near the said front rim of the axle box a. The said
passage is countersunk at 6¹, and tapped for a screw c. The screwhead c¹ of the
screw e may likewise as shewn have a thread like the screw c; and the countersunk
part b¹
may in that case be also tapped. The underface of the screwhead c¹, and the
seat or bed of the countersinking 6¹ are suitably roughed to grip the washer e which
is made of softer material. The said ronghed parts on c² and project and are set
with, and in the direction for, the screwing of the screw c, but the said roughed parts
are set against or in resistance to the unscrewing of the screw c.
The said roughed
parts when the screw c is driven, grip the washer e to keep the screw c from becoming
loose. The axlebox a. is shewn with a flange by which the said axlebox may be
bolted to the nave of a wheel of a road vehicle; but the aforesaid improvements may
also be applied to axleboxes, or lubricating cups for the wheels of road vehicles, when
the axleboxes are attached to the said wheels by being screwed on the naves of the
said wheels.
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) In connection with an axlebox, or lubricating cup of a road vehicle, a hole or
lubricating passage at or near the front rim of the said axlebox or cup substantially as
and for the purposes described

page_text: (2) For a lubricating passage at or near the front rim of an axlebox of a road
vehicle a hole countersunk and tapped substantially as and for the purposes set
forth.
(3) For a lubricating passage at or near the front rim of an axlebox of a road
vehicle a screwed stop or screw substantially as and for the purposes set
forth.
(4) For a lubricating passage at or near the front rim of an axlebox of a road
vehicle the combination of a suitably roughed countersunk bed or seat, and of a screw
suitably roughed on the underface of its head, and of a washer of softer material
substantially as and for the purposes set forth.
(5) For an axlebox screwed on the nave of a wheel of a road vehicle, and for an
axlebox otherwise fastened to a nave of a road vehicle-a hole or lubricating passage
at or near the front rim of the axlebox, the said hole or passage countersunk and
tapped, the bed of the said countersinking suitably roughed, a screw with the rim of
its head screwed and the underface of its head suitably roughed, and a washer in
connection with the said roughed bed and the said roughed underface of the screw ;
substantially as and for the purposes set forth.
