PROVISIONAL SPECIFICATION.
An Improved Lubricating Axle Cap for Vans, Carts, Cabs, Carriages,
and other Vehicles to Facilitate the Oiling or Lubricating of the
Axle and other Parts or Bearings.
I FREDERICK EDMOND.HARVEY of Bedford Villa Beresford Road Kingston on
Thames in the County of Surrey Fruit Merchant, do hereby declare the nature of
this invention to be as follows:-
The lubrication of axles or bearings of vans carts cabs carriages and other
vehicles by the following method.
Boring a hole in centre of face of axle cap and threading the same or inserting
and fixing in hole a threaded hollow cylinder into which I fit a screw capped
ferrule (or hollow cylinder with flange attached) and which may be either a
separate part or have a stop at end of ferrule permitting such capped ferrule to be
unscrewed to full extent but preventing its entire removal. In the former case the
oil is inserted through the hole in the axle cap on removing the capped ferrule and
in the latter through a hole or slot cut or bored in the cylindrical part of capped
ferrule and which hole or slot is exposed on unscrewing ferrule to full extent.
This hole in cylindrical part of capped ferrule may be automatically closed by a
plug or stopper made of metal or other material pressed into or against the hole or
slot by a small spring fixed on the inside of such cylindrical part of ferrule. The
face of axle cap may be hollowed or countersunk to permit of capped ferrule being
screwed up flush with outer surface of cap.

COMPLETE SPECIFICATION.
An Improved Lubricating Axle Cap for Vans, Carts, Cabs, Carriages,
and other Vehicles to Facilitate the Oiling or Lubricating of the
Axle and other Parts or Bearings.
I FREDERICK EDMOND HARVEY of Bedford Villa, Beresford Road, Kingston-
on-Thames, Fruit Merchant, 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 an improved lubricating axle cap for vans, carts, cabs,
carriages and other vehicles to facilitate the oiling or lubricating of the axle and
other parts or bearings and has for its object to effect such oiling or lubrication
without removing the cap entirely as is necessary according to the present axle
caps by which a considerable amount of lubricating material is wasted and also
saves the employment of experienced hands to lubricate as is necessary with old
method and also prevents stripping the thread as is frequently done by removing
and replacing caps.
And in order that my said invention may be fully understood I will proceed to
describe the same with reference to the accompanying sheet of drawings in which
Fig. 1 shews vertical section of my improved cap in position,
Fig. 2 top plan of same,
Figure 3. elevation shewing cap open ready for oiling and

page_text: a. shews the cap, 6 cover of same provided with screw thread c, d shews stop
pieces, e hole for lubricating, f. screw flange, y. cross slot, internal flange,
i washer.
The cap is screwed into the box of the wheel by the flange and when it is
required to lubricate the axle it is simply necessary to unscrew the cover b (which
being milled as shewn in Figure 3. may be effected without any tool, or if preferred
may have a cross slot and use a screw driver or other tool) after which the
cover b. is pulled out until the stops & come in contact with the internal flange h.
when the hole e is uncovered and the whole assumes the position shewn at Figs. 3
and 4. The oil can then be poured into the hole e. the cover b pushed back and
screwed into cap a. by which there will be no loss of lubricating material as the
hole e is kept uppermost until the thread c. reaches the cap a and the cover being
guided there is no fear of stripping the thread c, as is now frequently the case with
ordinary caps in which the thread f. is stripped. It will be seen that the cover b.
forms a cylinder in which the lubricating material is held during charging.
My improved lubricating cap may be applied to existing caps by cutting off the
face of said caps fastening in the internal flange and having a female thread for
the thread c. of cover b. to screw into.
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. My improved lubricating axle cap consisting of loose screw cover b. provided
with hole e. stop pieces d. in combination with cap a. and internal flange h. all
substantially as and for the purposes specified.
2. The improved lubricating axle cap substantially as set forth.
