COMPLETE SPECIFICATION.
Improvements in the Lubrication of Journals and Journal
Bearings.
We, JOHN MCFARLANE, Engineer, of Abbott's Road, Poplar, and WILLIAM
REID, Merchant, of Fenchurch Street, both in the County of London, do hereby
declare the nature of the said 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 improved means of effecting the lubrication of journals
of shafts, axles and like rotating parts, and of journal-boxes, axle-boxes, pedestals,
hangers, wall fixed and other journal bearings in which such shafts, axles and the
like rotate.
The invention is illustrated on the accompanying drawings in Figs. 1 and 2, as
applied to the journals of a shaft, and in Figs. 3 to 6 as applied to journal
bearings.
Fig. 1, represents, in elevation, partly in section on a, b, Fig. 2, the journal of a
shaft adapted according to the present invention.
Fig. 2, represents the same in transverse section on c, d, Fig. 1, supported by a
pedestal.
Fig. 3, represents, in end elevation, partly in section on e, f, Fig. 4, journal-
bearings adapted according to the present invention.
Fig. 4, represents a plan view, partly in section on the line g, h, i, Fig. 3.
Fig. 5, represents, in end elevation, a tram-car journal bearing; and,
Fig. 6, represents the same in plan.
The invention consists in forming the wearing surface of such journals 5, and
journal-bearings 6, (both separately and conjunctively,) with recesses 7, adapted to
receive a packing 8, of leather, asbestos or other suitable absorbent of the lubricant
used, which is packed thereinto; and in forming such journals and journal-bearings
with reservoirs 9, of the lubricant used, the same communicating, by suitable
ducts 10, with said recesses 7, and supplying the lubricant thereto and to the
absorbent packing 8, therein, by which latter it is conveyed to the wearing surface
of the journal or journal-bearing.
The recesses 7, may be made parallel with the axis of the journal or journal-
bearing, as represented, or they may be made at any suitable inclination thereto,
and they may be made of any suitable depth, width, length and shape, and may be
situated where of most advantage, and may be made in any suitable number. When
made in the journals of a shaft, such journals are preferably, but not necessarily,
enlarged, as represented in Figs. 1 and 2, to facilitate the cutting of the recesses 7.
The reservoirs 9, may also be made of any suitable dimensions and shape, by
casting, moulding, drilling, machining, or otherwise, and may be situated where of
most advantage. The reservoirs may be made with one or more suitably positioned
inlet openings 11, for supplying the oil or lubricant which may be normally closed
by screw-plugs 12, or other means.
The ducts 10, communicating between the recesses 7, and reservoirs 9, may also
be of any suitable dimensions, shape, situation and number.
The reservoirs 9, in the half parts of journal-bearings, may be separate and
separately charged with lubricant, or they may communicate by ducts 13, vide
Figs. 3 and 4.
The reservoirs may be formed separate from the journal bearings and communicate
with the absorbent packing 8, by piping, but we prefer to make the reservoir in the
hearings

page_text: Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is ;-
-
1. The hereinbefore described improved means of lubricating journals of shafts,
axles and like rotating parts, and journal-boxes, axle-boxes, pedestals, hangers,
wall-fixed and other journal-bearings in which such shafts, axles and the like rotate,
both separately and conjunctively.
2. Forming the wearing surfaces of such journals and journal bearings (both
separately and conjunctively) with recesses adapted to receive a packing of leather,
asbestos or other suitable absorbent of lubricant, which is packed thereinto, and
forming such journals and journal-bearings (both separately and conjunctively) with
reservoirs for lubricant, and ducts communicating therefrom with said recesses and
adapted to lead the lubricant thereto and to the absorbent packing, by which it is
conveyed to the wearing surfaces of the parts.
Dated this 26th day of January 1894.
