page_text: PROVISIONAL SPECIFICATION left by William Clark at the Office of
the Commissioners of Patents, with his Petition, on the 13th October
1860. A communication from abroad by Mr. Napoléon Jourdan, of
Paris, in the Empire of France, Proprietor.
I, WILLIAM CLARK, of 53, Chancery Lane, in the County of Middlesex,
Engineer and Patent Agent, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN LUBRICATING APPARATUS," to be as follows:-
This Invention. relates to a new and peculiar arrangement of oil box for
railway carriages, which lubricates in a self-acting and continuous manner the
whole extent of the journal of the axle. This improved oil box is also appli-
cable for the lubrication of all other kinds of axles and shafts. The peculiar
arrangement of oil box of this Invention consists in the application to the two
extremities of the journal of a throated disc furnished with concave spaces or
spatulas, which, while participating in the rotary motion of the journal, take
up the oil contained in the reservoir of the boxi and throw it into the cavity
made in the bearing for the purpose; from thence the oil runs on to the journal
by conducting holes which communicate with distributing grooves, spreading
the oil equally throughout the surface of the journal. The oil may also be
made, by a peculiar arrangement of discs, to run on to the axle journal direct
instead of from the bearing.
In the annexed Drawing is represented an arrangement of oil box according
to this Invention.

page_text: Fig. 1 shows a longitudinal vertical section of an oil box through the journal
on line 1, 2, Fig. 3; Fig. 2, a side elevation of the oil box; Fig. 3, plan of
the same; Fig. 4, vertical section on line 3, 4, Fig. 5; Fig. 5 represents a
journal furnished with a disc in which the oil runs directly on to the journal;
while Fig. 6 shows a plan of the disc furnished with hollow spaces or spatulas
for holding oil. In these Figures the same letters of reference indicate like
parts seen in different positions.
a, oil box of cast iron, in two parts, in which are made two hollow spaces b,
serving to contain the two discs j,j, keyed on the journal. The lower part of
the box is furnished with an oil reservoir c, of a relatively large size, in which
the discs j, j¹, are always partially immersed, for the purpose of lifting up the
oil and distributing it on bearing e. A second reservoir or channel v, below
the former, is arranged, for the purpose of facilitating the exit of the dirty oil
when cleaning the box; for this purpose it has an orifice in the front closed
by a screw plug; f, journal of the axle in which the bearing e rests; on the
upper face of this bearing there is a space g, into which the oil is directed by
means of discs j,j'. The oil is conducted on to the bearings by means of two
holes h, h; 1, annular segment or bevilled washer fixed to journal f, it turns in
a groove made in a leather collar k, to prevent oil from leaking out of the box
and also all introduction of foreign matters. This collar is also enclosed within
another collar of leather, india-rubber, or other elastic material, fitted tightly
into a space made in the side of the box; a cap a screwed to the side of the
box serves to tighten the collars more or less, as required; m, lip cast on the
box, serving for the introduction of the oil; this lip may be furnished with a
level to indicate the quantity of oil contained in the reservoir; the cover of
the lip bas a spring attached, for closing it automatically; n, exterior or ear
pieces forming slides, in which the guard plate o engages; j,j¹, discs of bronze
or other metal keyed on journal f; one of these discs ; has a rim p and
washer, so as to prevent oil from escaping at the back of the box; these discs
are furnished as represented with spaces for lifting and supplying the oil to
cavity 9;r, disc which may be substituted for j, j¹; it is furnished with spaces
either curved or not, as seen in Fig. 6; in this case the oil runs directly on to
the journal by reason of the connection between the bearing and journal; s,
springs fixed to box a by means of plate t, held by bolts u.
