An Improved Automatic Lubricating Apparatus for Lubricating the
Axles of Corves, Hutches, Coal Tubs, and such like.
I, ROBERT ARMSTRONG, of Carfin Road, Motherwell, Lanarkshire, Colliery
Manager, do hereby declare the nature of this invention to be as follows:-
1
This invention relates to a fixed apparatus for lubricating the axles of corves,
hutches, coal tubs and such like.
The lubricant is contained in a grease box or tank which is sunk in the ground
between the rails. Fitted rigidly in the grease box are two discs or partial
discs arranged one at each side of the box in such position as to be just below
the journals of the passing hutches or such like. The discs are each provided
with a strip of spring metal which is bent round the periphery and whose ends
leave a gap of an inch or two at the top. A bent plate spring is also secured
to the discs in such manner as to tend to force the ends of the circular spring
apart or upwards. Passed right round the circular spring is an endless chain
preferably having rectangular links and whose joints are so made as to on the
one hand lift the grease up from the grease box as the chain revolves and on
the other hand so as to be readily caught and pushed forward (so as to move the
chain) by the journal of a passing hutch.
When a hutch passes over the lubricating apparatus its journals bear upon
the upper part of the chains of the two discs lifting grease therefrom so as to
lubricate the journals and at the same time moving the chains one or more links
so as to present fresh grease to the next succeeding hutch.
Each disc would, by preference, be made with flanges serving as a guide groove
for the chain, or metal plates serving the same purpose may be secured at each
side of the disc.
Each disc may, if so desired, be inserted in a separate grease box.
The discs have preferably a segment cut off their upper ends so as to form a
flat surface for supporting the distending spring.

An Improved Automatic Lubricating Apparatus for Lubricating the
Axles of Corves, Hutches, Coal Tubs and such like.
I, ROBERT ARMSTRONG, of Carfin Road, Motherwell, Lanarkshire, Colliery
Manager, 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 a fixed apparatus for lubricating the axles of corves,
Eutches coal tubs and such like

page_text: In order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, whereon:-Fig. 1 is a plan view
showing the lubricating apparatus fitted between the rails, A, A. Fig. 2 is a
cross section of the apparatus and showing the axle of a coal hutch being lubri-
cated. Fig. 3 is a longitudinal section of the grease box taken on the line X, X.
Fig. 1.
Fig. 4, is a side view and Fig. 5, a plan view of the grease chain used with
the apparatus.
Fig. 6, shows a modification.
The lubricant is contained in two grease boxes or tanks a which are sunk into
the ground between the rails as shown at Fig. 2. These boxes may rest, on a
platform B. Fitted rigidly in each grease box a is a partial disc b, or a disc
with a segment cut off it, arranged in such position as to be just below the
journals of the passing hutches or such like. Each disc is provided with a strip
of spring metal c which is bent round its periphery and whose ends come within
a short distance of each other leaving a gap of an inch or two at the top. Two
spiral or other springs d (see Fig. 3) each provided with flat headed pins e of
a smaller diameter than the internal diameter of the springs are fitted in recesses
in the disc b. The springs and pins e press upwards in such manner as to
tend to force the ends of the circular spring e apart or upwards.
Passed right round the circular spring is an endless chain f. This chain,
as shown more particularly at Figs. 4, and 5, consists of a number of rectangular
links 9 jointed together by spoon shaped joint pieces h. These joint pieces each
consist of a curved flat blade having a ring shaped end h which latter serves as
a joint for securing two neighbouring links together. The curved blade fills
up the opening of the link. The chain so made, on the one hand, as it revolves,
elevates the grease C up out of the grease box a, and, on the other hand, can
he readily caught, at the circular projecting parts h, by the axle i of a passing
hutch and pushed round the disc b.
When the hutch j passes over the lubricating apparatus the journals of its
axles bear upon the upper part of the chains f lifting grease therefrom so as
to lubricate the journals and, at the same time, move the chains one
more links so as to present fresh grease to the axles of the next succeeding
hutch.
or
Metal plates may be bolted by the bolts to the discs b. These bolts Z also
serve to secure the discs in place. The plates are larger in diameter than the
wood discs so that they, in conjunction with the outer side plates of the boxes,
form grooves for guiding the chains f as they move round the discs. If desired
instead of using metal plates & the discs may be provided with flanges for the
same purpose.
Under a modification the partial dise b may be made of cast metal and of the
shape shown at Fig. 6. A peripheral groove 61 (see dotted line) is made roun
the disc for the purpose of guiding the chain. In this case the spring c may be
curved as shown and have its end working in the groove b¹. Saddles c¹ may be
secured to the spring e for the purpose of guiding the chain f
The action of the apparatus is such that the automatic lubrication of the
journals of each hutch is assured every time it passes over that part of the rails
where the grease boxes are situated.
If desired a single large sized grease box may be used in which two discs b
are fitted instead of having two separate grease boxes each with a single disc.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I consider novel and desire to claim is:-
(1) An automatic lubricating apparatus constructed substantially as herein-
before described with reference to the drawings annexed.
(2) An automatic lubricating apparatus characterized by a grease box having

page_text: a fixed disc provided with a spring ring or equivalent (c) said ring or equivalent
supporting a grease chain (f) which can be turned upon the disc by the contact
with it of the journals of a passing hutch.
