THE COLLIERY GUARDIAN.

July 17, 1914.

employed in coal mines, for checking the number of corves
or tubs of coal delivered by the miner, which usually con-
sists in marking on the side of the tub a plurality of lines,
the number of which correspond to the full tubs of coal
delivered by the miner. Suitably shaped counters or marks
are provided, intended to be slipped over a bracket into
position, between two of the division pieces, the distance
between each successive pair of which will, for preference,
retain ten of such marks, each mark intended to signify or
denote a loaded corve of coal, or any other object, the number
of which it is intended to check. When the bracket con-
tains its full complement of marks, or at the end of a
day’s work, means are provided whereby the bracket may be
lowered, thereby causing the marks or counters to slide off
by force of gravity into a suitable receptacle secured to the
end of the bracket to receive them, such as a wire hoop.
Fig. 1 is a side elevation showing the bracket in its normal
or raised position; fig. 2, a similar view, but showing the
bracket lowered with a receptacle attached to the end thereof;
fig. 3 is a front elevation of one of the marks or counters.
In the drawings, the bracket a, which is preferably of L-sec-
tion, is pivoted at b to any suitable support c, and is
provided at intervals along its length with distance or
division pieces d, each of which is pivotally mounted to the
upstanding side of the L-sectioned bracket and adapted to
normally lie in a prostrate position along the bracket. To
retain the bracket in its upwardly inclined or normal position
the pivoted end thereof is bent at an angle of preferably
100 degs. thereto, the lower end of which is provided with
a catch or, if desired, a lock e, which in its simplest form
may consist in the provision of a clearance hole formed in the
bent portion of the bracket, adapted when in the normal
position to coincide with a similar hole in the support c
and retained by a peg or the like inserted therein. To the
outer end of the bracket a is secured a receptacle or the like
f, which in the drawings takes the form of a semi-circular
hoop of wire or strip intended to retain the falling counters g.
The counters g are formed, for preference as in fig. 3, in the
shape of a rectangle, or other shape as desired stamped from
sheet metal, and having an oblong slot g1 formed therein so
as to clear the prostrate division pieces d when being placed
in position on the bracket. It will thus be seen with the
present device the numbers of corves or tubs filled in a day,
or any specified time, may be readily reckoned at a glance,
by reason of the counters being portioned into periods of ten
by the division pieces provided, which are so positioned as
to include this number, or any other desired number, there-
between. (Four claims.)

29102 (1913). Improvements in Mechanical Stokers. E
Bennis, of Beech Hill, Astley Bridge, Bolton, Lancashire.—
Relates to mechanical stokers of the Bennis' type for supply-
ing fuel to steam boiler and other furnaces, and consists in
improvements in details of construction whereby the feature
of detachable shovel arms working outside the shovel box

is combined with a shovel shaft journalled in bearings
formed in the removable cover, and a lever for reciprocating
the pusher by a waved cam on the driving shaft. Fig. 1
is a sectional elevation with cover B1 open; fig. 2 is a plan.
(Two claims.)
