PROVISIONAL SPECIFICATION. -
Improved Lubricating Axle Cap for Road Vehicles of all
descriptions.
WILLIAM MARK HOLDOM 22 Gibbon Road. Richmond Road, Kingston-on-
Thames, Surrey, Cabinet Maker. I do hereby declare the nature of this invention
to be as follows:-
Improvements in axle caps for buses, carriages, vans, carts and every other kind
of road vehicle.
To facilitate the oiling of the axle and bearings without the trouble of removing
the cap from the wheel and dispensing with the use of tools. And in what manner
the same is to be performed to be described and ascertained in and by following
statements.
My invention consists of an improved form of lubricating axle cap applicable
to road vehicles of all descriptions which while being easily accessible has not to be
removed from the wheel. Hitherto in an ordinary axle cap great difficulty has
been experienced in keeping the axles and bearings properly oiled. I propose to
obviate this by an axle cap with oil hole drilled and tapped in the centre. On the
axle cap I eccentrically place a screw on which is fastened a disc with hole in
centre concentric with the axle cap in such a manner that the disc can be swung
aside when necessary.
The disc fits into an outer cover and is held therein by a
slight lip in any convenient manner which while preventing it coming away yet
allows it to rotate freely on a screwed boss on the outer cover. On the inside
centre of the outer cover is the screwed boss before mentioned which passing through
the screwed centre hole in disc herein before mentioned engages with the screwed
oil hole in axle cap and screwing down, wedges itself against the axle cap and
makes a tight joint independent of the tight joint made by the disc. To prevent
the disc swinging further than necessary a small stop is formed on the face of axle
cap and a corresponding recess at edge of disc.
The method of working is as follows. To uncover the oil hole rotate the milled
or other edged outer cover which is rotating on the disc until it disengages with
the axle cap and then swing it aside which it will freely do, as the disc is held by
the eccentrically placed screw in axle cap.
I purpose making the improved lubricating axle cap from any kind of metals best
suited for its various parts.
I do not restrict myself to the precise details hereinbefore described.

Improved Lubricating Axle Cap for Road Vehicles of all
descriptions.
I WILLIAM MARK HOLDOM of 22 Gibbon Road Kingston-on-Thames in the
County of Surrey Cabinet Maker 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 consists of an improved form of axle cap, applicable to road

page_text: vehicles of all descriptions, which while being easily accessible, has not to be
removed from the wheel.
Hitherto in an ordinary axle cap, great difficulty has been experienced in
keeping the axles and bearings properly oiled.
I propose to obviate this by an axle cap with oil hole drilled and tapped in the
centre; 'on the axle cap I ec entrically place a screw or pin on which is fastened a
disc out of centre, with hole in centre, concentric with the axle cap in such a
manner that the disc can be swung aside when necessary. The disc fits into an
outer cover and is held therein by a slight lip in any convenient manner, which
while preventing it coming away, yet allows it to rotate freely on a screwed boss
on the outer cover. When disc is held by a screw eccentrically instead of a pin
eccentrically the rotating of cover, when moved in order to expose oil hole,
carrying with it the disc, causes said disc and cover to rise away from top of axle
cap. On the inside centre of the outer cover is the screwed boss before mentioned,
which, passing through the screwed centre hole in disc hereinbefore mentioned
engages with the screwed oil hole in axle cap and screwing down, wedges itself
against the axle cap and makes a tight joint independent of the tight joint made
by the disc. To prevent the disc swinging further than necessary, a small stop is
formed on the face of axle cap and a corresponding recess at edge of disc.
The method of working is as follows:-To uncover the oil hole, rotate the milled
or other edged outer cover which rotates on the disc until its centre screw
disengages with the axle cap, and then swing it aside, which it will freely do, as the
disc is held by the excentrically placed screw in axle cap.
I purpose taking the improved form of axle cap of any kind of metals.
I do not restrict myself to the precise details herein before described.
The description of the drawings is as follows:-
A is the hollow cover which has a screwed boss. a entering through disc B into
top of axle cap D making when screwed up close a ground oil tight joint.
B is a loose disc which is excentrically secured by means of screw C to axle
cap D. E is a screw or other projection, which prevents lip on disc B from
rising completely out of cover A. G is a pin which stops cover when fully open
and also sets the cover in its right position for screwing the screwed boss a into
axle cap D when closed. H is a hole in which a key may be inserted to facilitate
moving the cover if necessary.
Fig. 1 represents my improved form of axle cap when cover is open, ready for
oiling.
Fig. 2 when cover is closed.
Fig. 3 is a section of axle cap, cover, and disc. Fig. 4 is front view of same.
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. An improved axle cap.
2. The cover swinging by means of an excentric on axle cap as hereinbefore
described.
3. The method of making an oil tight joint by means of grinding the top of axle
cap and underside of cover together metal to metal.
4. The arrangement of cover, excentric and axle cap substantially as set forth.
5. The application of my invention to existing axle caps.
6. The movement of uncovering oil hole, causing the disc and cover to rise
slightly away from cap by means of screw C.
