and is operated by means of the usual type of pedal.
The current is supplied through overhead conductors
to a switchboard fitted in the house shown on the left
of the elevator. (Fig. 5.) The main switches, with
the overload and no-volt cut-outs for the various motors,
are mounted on this board, and the controllers for the
elevator and coal crusher motors fitted in the house,
thus bringing the control of all operations in connection
with the plant readily under the hands of the man in
charge.

Two 15 cwt. electrically-driven coaling cranes have
been provided for coaling the locomotives at such times
as the elevator is out of use. These are fitted at one

The Diario Oficial (Bogota) contains a Law authorising the
Colombian Government to contract a loan or loans to the
sum of 400,000 pesos gold (about £80,000) for the extension
of the Tolima Railway to the town of Ibagud.

Tenders will be received at the offices of the Civil Govern-
ment, Castelo Branco, Lisbon, up to 1 p.m. on September 30,
for concessions for working certain metal deposits in the
Castelo Branco administrative district.

Pig Iron Prices.—With reference to the Order made by the
Minister of Munitions on July 7, 1916, bringing metal-
lurgical coke, pig iron, and certain classes of steel under the
provisions of Defence of the Realm Regulation 30a, the
Minister of Munitions gives notice that the general permit
under the above Order dated July 7, 1916, is modified by the
insertion in the schedule thereto of the following revised
maximum prices for the articles specified, in substitution for
the maximum prices contained in the schedule as published,
and in addition to the revised maximum prices contained in
the Notice of August of August 15, 1916 :—Revised maximum
prices for pig iron. Derbyshire, Leicestershire, and Notting-
hamshire pig iron. Present prices per ton net f.o.t. makers’
works : Forge, £4 5s.; foundry numbers, £4 7s. 6d. Price
as amended per ton net f.o.t. makers’ works : No. 4 forge,

general use at this shed.
Special means are provided to
prevent undue breakage of
coal when delivering into the
bunkers.

Four delivery shoots (fig. 5)
are provided for coaling loco-
motives, two on each side, thus
enabling four locomotives to
be coaled at one time if desired.
Each shoot is provided with
means for readily measuring
the quantity of coal delivered,
the capacity of each measure
being 10 cwt.

An electrically-driven wagon
tipper (figs. 4 and 5) has been
provided for dealing with end-
door wagons. The tipper table
is hinged at one end, and the
other end is raised by means of
steel wire ropes coupled up to
the hoisting drums of an elec-
tric winch fitted in the house
overhead. Hooks are fitted
on the table for gripping one of
the axles of the wagon; these
are operated by a hand lever
fitted on the side of the table.
The tipper is controlled from
the ground level by means of
“ up,” “ down,” ■“ stop ” push
buttons, fitted in a suitable box
on one of the uprights support-
ing the machinery. Switches
are fitted at both “ up and
“ down ” limits, so that, in the
event of the operator neglect-
ing to press the 11 stop ” button
the current will be cut off and
the table brought to rest at
these pre-determined points.

end of the overhead bunkers, and are attached to the
uprights supporting the same; they are arranged to lift
the coal in tubs from the ground level on to the loco-
motives, for which purpose they can be slewed through
an angle of about 150 degs.

The lifting and slewing motors and gearing, together
with the controllers, which are of the universal drum
type, are fitted in the house shown under the end of
the bunker. Four engine water columns are fitted on
each side of the bunker, two at each delivery shoot,
so that it is possible for locomotives to take water at
the same time as they are being coaled.

Under normal conditions the average number of loco-
motives coaled at this shed is about 135 per day,
requiring approximately 275 tons of coal, and as the
elevator is designed for a capacity of 50 tons per hour,
it is only necessary to run the plant during the day
time. The time occupied in putting four tons of coal
on to a locomotive is three minutes, and as the average
quantity of coal required by each locomotive is about
two tons, it will be readily understood that the method
of coaling by this plant is much more expeditious than
under the old system of coaling, as well as effecting a
considerable reduction in the labour involved.

Gazette for the illustrations of the plant described
above.

Owing to the end-door type of wagon being fitted with
doors at one end only, it was necessary to provide the
turntable shown in figs. 1 and 3 to enable these wagons
to be turned.as required for tipping. The capstan shown

was provided for the purpose of turning the wagons on
the turntable, and also to assist in bringing them to the
required position over the hopper or on the tipper table.
