486 THE COLLIERY GUARDIAN. March 7, 1913. and kitchen with accommodation for over 1,000 men. The dining-room (see fig. 7) is divided into compart- ments for the different grades of workpeople. A hot dinner is provided every day at a moderate price, and those men who bring their own food can have it warmed or obtain hot water without any charge. Adjoining the ground floor of this building is the workmen’s lavatory, of which an illustration is given in fig. 6. It is fitted up with long cast iron troughs which are filled with warm water at mealtimes, and each man is provided with soap and towel. In this building, lockers constructed of metal and well ventilated are provided so that each man has a place in which to hang his coat it being forbidden to take these into the shops. Another new building is a three-storey structure at the rear of the power-house (see fig. 2), it is of fireproof construction throughout, with steel framework, the floors and roof of reinforced concrete, and the whole enclosed by brick walls. It is occupied on the top floor as a pattern shop, the first floor as pattern stores and paint shop, and the ground floor as a tinsmith’s shop, and for cotton bowl making. The latest addition is a building with seven bays which is used as a brass and iron foundry and smithy. It measures 275 ft. by 218 ft. 6 in., and is lofty, well lighted, and supplied with materials by means of a line of rails of standard gauge which runs from the firm’s own siding on the Lancashire and Yorkshire Railway. From this siding lines of standard-gauge rails also run into bays in each department of the works, as is shown on the plan fig. 2, and the raw material and finished products can be unloaded and loaded direct from and into trucks, thereby saving unnecessary handling. Further than this, a complete system of narrow-gauge tramway lines, 21J in. gauge, is laid in each bay, and trucks capable of carrying 2 tons are employed to convey goods from one department to another. The trucks run on roller bearings to reduce friction, and can easily be pushed about the shops by one man. All the bays of the main building are of the same length. The average height under the cranes is 24 ft., and each shop is served by a powerful overhead electric travelling crane running the whole length of the building. There are in addition pneumatic hoists and jib cranes operated by hand and placed over the benches. The shops are illuminated at night by means of metal filament lamps, each of 1,000-candle power, distributed equidistantly from one another, and so arranged to avoid the throwing of shadows. The ventilation and heating have been well considered. The energy to drive the whole of the works is taken from the Manchester Corporation electric supply mains. Alternating current is brought into the works at a pressure of 6,500 volts and is transformed in the power house down to direct current at 440 volts.

Fig. 7.—Workmen’s Dining Hall is distributed on the three-wire system, so that two pressures are provided. The large machine tools are driven independently by their own electric motors and the lighter tools are operated from sections of overhead line shafting, each section being driven by its own motor. Ample provision is made for testing all pro- ducts. Water for manufacturing, fire, and other purposes is obtained from a large reservoir into which all the rain water from the roofs, &c., is drained. From this reservoir the water is forced by means of a turbine pump through one of the firm’s mechanical pressure filters, which has a capacity of 6,000 gallons per hour. From the filter the water flows into a large elevated tank placed in the tower shown in the illustra- tion, whence a constant pressure is maintained in the circulating mains. The whole of the offices and shops are equipped with a model fire extinguishing plant. This includes some 4,000 Grinnell sprinklers divided into eight distinct in- stallations, each controlled by a separate set of 6 in. alternate wet and dry pipe valves. Water is supplied by an 8 in. pipe from the Corporation main, augmented by a gravity tank of 10,000 gallons capacity and an electrically driven turbine pump capable of delivering 1,000 gallons per minute. In connection with this pump there is provided automatic starting gear. Briefly, this consists of a vertical hydraulic cylindei- in which is a weighted ram ; the latter is held in position at the top of the cylinder by means of a catch controlled by the pressure of water in the sprinkler installation. When this pressure is reduced to a predetermined extent by the opening of one or more sprinklers in case of fire, the catch releases the ram, which falls by gravity and starts the electrically driven turbine pump, which con- tinues to work until stopped by hand. As soon as the pump has been started the ram is automatically raised
