April 9, 1915. THE COLLIERY GUARDIAN. 767 THE “SIMPLEX” CHEMICAL FIRE EXTINCTEUR. The form of “ Simplex ” extincteur now made by Messrs. Mather and Platt Limited has been specially designed to meet the requirements of the British Government, who have placed an order with the firm which is believed to be the largest ever given for fire extincteurs in this or any other country. The type of extincteur which Messrs. Mather and Platt are now putting on the market is identical with the Government appliance in every detail, with the sole exception of the royal cipher. The “ Simplex ” extincteur depends for its operation on the reaction of sulphuric acid upon a bicarbonate of soda solution. The acid is contained in a hermetically sealed bottle, suspended over the liquid, which is dis- charged through the jet upon smashing the bottle by striking a knob at the top of the extincteur. The fluid, which has great extinguishing power, is ejected to a distance of 50 or 60 feet. In this appliance there are no valves or rubber hose, whilst the jet orifice is protected from glass splinters or other foreign material by a cone-shaped sieve. An opening at the top, 3 in. in diameter, is provided, through which the acid bottle can be withdrawn, should it be desired to examine the interior. The body of the extincteur is constructed of 16 S.W.G. steel, and tested hydraulically to a pressure of 350 lb. It is coated thickly with lead in the centre, and with tin at the top and bottom, both inside and outside, to prevent corrosion, and every seam is riveted as well as soldered. After testing, the extincteur is handsomely enamelled, the brass parts highly polished and then lacquered. The chemicals with which the machine is charged undergo no change, and the extincteur will operate as satisfactorily after 10 years as on the day on which it was first charged. A special wall bracket has been designed by which the extincteur is retained in a convenient position for use. In one form this bracket holds the extincteur on the lid of a metal box containing new charges, and a brass pin, which must be withdrawn before the appliance can be operated, keeps it safe from any risk of' accidental discharge. OBITUARY. A prominent member of the Durham Miners’ Association passed away last week, by the death of Mr. Stephen Turnbull, of New Seaham. Mr. Turnbull, who was 64 years of age, had been checkweighman at Seaham Colliery for nearly 35 years. He was a member of the council of the Durham Miners’ Association for a quarter of a century, a trustee of the Seaham Miners’ Hall, and a member of the Seaham Parish Council from its inception. In the disastrous explosion at Seaham Colliery, in 1880, he formed one of the exploring party. Mr. George Monkhouse, who died at Carlisle last week at the age of 80, was a prominent figure in the Cumberland mining world a generation ago. His father was engaged in the sinking of the Bullgill and Rosegill Collieries, near Maryport, and he himself was for some years manager of the Hesketh mines. He retired about 20 years ago. He was an enthusiastic meteorologist, and at his private observation station at Gilcrux he did useful work for the Meteorological Office. Mr. J. P. Walton, who died on Sunday last, at his residence, Acomb High House, near Hexham, was a member of the firm of Messrs. Walton and Cowper, who, half a century ago, leased the Fallowfield lead and coal mines. The chief output from the mines is barytes, of which many thousands of tons were exported. Of late years, the firm opened out a colliery near the adjoining village of Wall, but, owing to the war, mining operations there have been suspended for some time. Work is, however, to be resumed there in a few days. Mr. Walton, who has died at the age of 76 years, was pre-deceased by his partner, Mr. Cowper, in 1875. He is survived by Mrs. Walton, two sons—the elder of whom, Mr. James Walton, has been assisting his father in the management of the mines - and four daughters. His second son is serving as second-lieutenent in the Northumberland Fusiliers. LABOUR AND WAGES. South Wales and Monmouthshire. The notice presented by Mr. Tom Richards, M.P., secretary of the South Wales Miners’ Federation, will formally terminate the existing Conciliation Board agreement at the end of June next. The demand for amendment, made by the local federation, is supported by the national organ- isation, and it is sought to have present standard rates abolished and a new standard rate established which shall be 50 per cent, above the standard of 1879. Upon this, a new minimum wage rate of 10 per cent, is to be based. In addition, six turns for five is the payment sought for workmen on the afternoon and night shifts, and it is also demanded that all hauliers shall receive the same rate of pay. The coalowners on the other hand, who had these proposals before them a few weeks ago, argued that the present was not the time to negotiate for a new agreement; and they offered as .an alternative a war bonus of 10 per cent, on existing standard rates ; this was rejected by the workmen, who asked for
