PROVISIONAL SPECIFICATION.
Improvements in Hubs or Axleboxes of Wheels for Colliery Trams.
MASSINETH MOORE, Mechanic, 4 Incline Terrace Ynishir near Pontypridd
Glamorganshire do hereby declare the nature of this invention to be as follows:-
The axlebox is casted in one entire piece and in such a manner as to obtain an
annular space (marked A in drawing of such capacity as may hold from one pint to
one quart of oil or other lubricant. The aforesaid annular space is traversed by a
vane marked V in drawing) casted in the periphery and sides of axlebox and
extends to within half an inch of the bush marked B in drawing. A. hole marked H
in drawing is formed in the aforesaid bush, directly opposite to the aforesaid vane,
the oil or other lubricant elevated by the vane V falls into the hole H when the
wheel revolves and thus lubricates the axle. On each side of the vane V slightly
raised webs are formed marked W in drawing to guide the oil or other lubricant
into the hole H. The screw plugs marked S in drawing may be removed
leaving holes through which the necessary oil or other lubricant is placed in the
axlebox.

COMPLETE SPECIFICATION.
Improvements in Hubs or Axleboxes of Wheels for Colliery Trams.
MASSINETH MOORE, Mechanic, 4 Incline Terrace Ynishir near Pontypridd
Glamorganshire 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 :-
The object of my invention is to provide an axlebox for the wheels of colliery
trams which shall to a greater or less extent, embody the following requirements.
Firstly, it shall contain a reservoir of oil or other lubricant. Secondly, it shall be
self lubricating and have a continuous feed when wheel is in motion. Thirdly, it
shall not lubricate when wheel is not in motion. Fourthly the reservoir of oil or
other lubricant shall be protected from all dirt and dust except such as may enter
with the oil when it is placed in the reservoir. Fifthly, it shall have a minimum
number of parts compatible with efficient working.
And in order that my invention may be better understood, I append hereunto
one sheet of drawings marked with letters of reference, the same letters in the
various figures indicating the same or like parts. The drawings here referred to
are those left with my "Provisional Specification," they consist of one cross-section,
and one view part in elevation and part in section; all the rim of the wheel and
portions of all the arms of the wheel being excluded.
I now proceed to explain my invention reference being had to the aforesaid
drawings.
The axlebox is casted in one entire piece with the arms and rim of wheel, as is
usually done with ordinary tram wheels which are not provided with oil or
lubricant reservoirs, and the axlebox is to be constructed in such a manner, as to
preserve an annular space, as shown marked A in drawings; this space shall extend
around the bush marked B in drawings, and shall be of such capacity as may contain
one pint or about of oil or other lubricant; the size of this space shall be made
suitably proportional to the size of wheel required.
At some point of the axlebox, the aforementioned space marked A shall be

page_text: traversed by a vane or partition marked V in drawings, which may be made of
either wrought or cast iron; the said vane shall have on each face of it, two raised
webs or corrugations marked W in drawings, precisely as shown in drawings; the
vane being fixed in the axlebox by being casted in the sides and periphery of the
axlebox; a space of about half an inch being allowed between the vane and
the aforementioned bush marked B in drawings.
The object of the webs or corrugations upon the vane, being to ensure that the
whole oil or lubricant even to the last shall be utilized for oiling or lubricating.
The bush marked B in drawings, may either be casted as part of the same casting
as axlebox, or it may be a wrought iron bush fixed in the mould before casting, or
otherwise fastened, it may also be constructed of alloys, such as brass, gunmetal, or
other bushing metal.
Directly underneath, and opposite the aforesaid vane, a small hole marked H in
drawings is formed in the aforesaid bush marked B, and by means of this hole, the
axle communicates with the reservoir of oil or other lubricant.
When the wheel revolves, the oil or other lubricant in the space marked A, is
elevated by the vane marked V, and by means of the webs or corrugations
marked W, is conducted to the aforesaid hole marked H in the bush marked B, and
thus labricates the axle; the size of the hole being so regulated as to avoid an
excess of feed and waste of oil or lubricant.
The screw plugs marked S in drawings, two or more of which may be necessary,
are used to plug up holes which may be required to clean out the core of the mould
after casting, these holes are also employed to place the necessary oil or other
lubricant in the axlebox.
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 :-
Firstly. An axlebox as herein set forth, containing a large reservoir for oil or
other lubricant, the said reservoir being formed by the bush B (which extends
across the axlebox as shown) and the sides and outer periphery marked P of
the axlebox; substantially as described and according to the accompanying
drawings.
Secondly. The vane marked V, which traverses the aforesaid reservoir, and the
corrugations which are formed thereon for guiding the oil or other lubricant to the
hole marked H; the purpose of the said vane being to elevate the oil or other
lubricant when the wheel revolves.
