The length, when the screw is home, should be G in. less than the hf' ight of the earn in \\·hich the machine is to be used. The weight Yarie:- according to len~h (a 4 ft. column weighs 120 lb,). • 2. SEGMEN_T.-This is made in two types-the JD. and the shearing pattern.

L 3. DRILL.- The air drill is of special construction, particularly suited f_or coal cutting. It is provided with a safety arrangement, which pre~ents _bre~k~ges m_ the even! of the cutting bit not striking the coal or other matenal m wluch 1t 1s cutting or bormg. The weight of the standard size of drill is 264 lb. 4. EXTENSION RODS.-Five rods, 20 in., 40 in., 60 in., 80 in. and 100 in._ long respec~h·ely are used. The weight of a set is 115 lb. .These arc made of steel with symm~tncally conically turned ends. One _end fits the dnll clmcl~ and the other the c_uttm_g bit. The conical ends ensure good gnps,. and at the same time can be very easily disconnected. To remove the e>.."i:ension rod from the drill chuck, use is made of a steel drift fitting into a slot in the drill chuck. 5. CUTTING BITS.-Weight, 5 lb. These are of 3 in. diameter, anUd adre made _of toodil-:~eel. They are usually provided with five cutting prongs or edges. n er certam con uons . . . it may be advisable to use bits with three or seven prongs. To disconnect the cutting bit from the extension rod the latter 1s held 1_n an upnght position, allowing the teeth of the bit to rest on the floor, and a sm_ar:t blow with a ha~~r is deli\'ered on the shoulder of the cutting bit. Thro~1gl~ stoking these blows it 1s evident that the extension rod will become dented, and 1t 1s ne~essal)'. that the dented end of the extension rod should always be used for tI:ie cutting bit, w~lst the other ~nd should always be inserted in the drill chuck.. To _a\'Old undue ham11;enng of_ the cuttmg bits it is recommended to use separate cuttmg bits for each extension rod • they need then be removed only for sharpening purposes. 5 4 �l NTERNALIONAl CHANNELLING MACHINES Ltd.

The compressed air which enters the cylmder d through ports_a 1 and c, drives the piston forward (as shown in section 1) or causes it to return (as shown :1 section 2). The piston valve is held in the position shown by_ means of the compressed air which passes through the port a 1 into the annular chamber g1 , simult~neously the c?mpressed air passes through the ports a and e into the chamber J. The surface sub1ected to the air-pr~sure in chamber J is, however, smaller than the one in the annular chamber g1, _so that the piston valve must remain stationary until the piston passes and opens the reversing port Ii :. \Vhen this takes place the compressed air rushes from the ?ylinder d throu~h the ports 1z _and ~-m~o.,.tl~e ann Iar space g, thus counteracting the pressure m g1, and the ~ir. pressure still existm_, m 11 chamber J causes the piston valve to reverse.

HE " SISKOL " holds the wor~d's record for the grea~est number of h~ading~ cut in one shift, i.e., ten places, averaging 10 ft. by 5 ft., which was accomplished in a 9-hour shift at Mainsforth Colliery, Ferryhill, Co. Durham. ThlS work was done with the assistance of a carriage fitted to the machine (see illustration opposite). The machine was run up to the face of the heading and two chocks were placed underneath the carriage in order to lift the wheels off the floor. The column was then fastened, and when the cut was finished the column was slackened, the chocks removed from underneath the carriage, and the machine was then :eady to be :nn into t~e n_cxt ? e~ding without any of the parts having to be detached. In this way the time occupied in fhtting was reduced to a minimum. This carriage is a simple contrivance, can be fitted to any machine and, of course, can be arranged to suit any gauge of rails. The best work of a competitive machl?e, handled_b)'. the maker~' experts and '".orking under precisely similar conditions, was the cutting of five similar places in an 8-hour shift. T The certificate given by the Manager of the Colliery at the time is as follows :DEAR SIRS, THE CARLTON IRON Co., LTD., MAINSFORTH COLLIERY, FERRYHILL, Co. DURHAM. • I hereby certify that the above statement of cutting ten (10) places, comprising 506 square feet, under 9 hours, with your newest type of "Siskol" machine, is correct. F. J. H.

[NTE.RNMJONAZ CHANNELLING MACHINES .ltd. RECORD SPEED FOR SINGLE HEADING. j\T the Barlborough No. 2 Pit, belonging to Messrs. The Staveley Coal & Iron Co., Ltd., one f i "SISKOL" Coal-Cutter drove a heading 12 ft. wide in the Top Hard Seam, 4 ft. 3 ins. thick, a distance of 66 yards in one week. The previous rate of progress by hand was 12 to 15 yards per week. Many Colliery Managers are inclined to be dubious about this performance, but the following particulars as to how the work was done may possibly remove such misgivings. • It was desired to get a single heading through a pillar of coal with the utmost possible speed. The size of coal obtained was immaterial, speed being the one essential. The seam was 4 ft. 3 ins. thick and the heading 12 ft. wide. A time table was drawn up as follows :6 to 7 Cutting. 8.40 to, 9.40 Cutting. 11.20 to 12.20 Cutting. 7 to 7.10 Shot-firing. 9.40 to 9.50 Shot-firing. 12.20 to 12.30 Shot-firing. 7.10 to 8.40 Filling. 9.50 to 11.20 Filling. 12.30 to 2 Filling. Work was carried on 3 shifts in 24 hours and the same schedule adhered to during the shifts n \ THE "SISKOL" COAL-CUTTER. 10 \ \ ' commencing 2 p.m. and 10 p.m. The men engaged on the work at the face were a machine operator and his assistant, a ccllier and two fillers. A small branch from the main air pipe enabled a filkr to bore the shot holes whilst the Coal-Cutter was in operation, the collier and the other filler setting the necessary timber ·and keeping .the rails up to the face. Two sets of rails were maintained. The fillers had nothing to do but fill, an~ there was no wa.it~ng for_ tubs. If more than the _allotted time were occupied in filling-say 1t took 1 hour 40 mmu!es mst~ad _of the schedule time of 1 ~our 30 minutes- IO minutes was taken off the next cuttmg penod m order to adhere to the timetable. Vlhilst the coal was being filled the ma.chine men were keeping the pipe range in order. No ripping was done until the road was through the pillar. 11 �CHANNELLING MACHINES Lid [NTERNATION.Al lNTERNATlON.Al CHANNELLING MACHINES Z td. T MACHINES F OR uHOLING" ONLY.

T HE illustration on the opposite page sh0\V$ the "SISKOL" fixed for shearing or nicking. In seams where longwall machines are used a " SISKOL " with a shearing segment is very useful in making vertical cuts at regc1la_r distances along the face in order to reduce the number of shots required, at the same time facilitating the getting of the coal and increasing the percentage of large coal. To change from vertical to horizontal cutting, or in fact to any angle, it is only necessary to slacken the nut fastening the segment (shearing type) in the cone of the sleeve or clamp which is attached to the column. --------.J\-THE ".SISKOL'' COAL-Cl!TTER. 18 19 �iN7ER.NA'rlONAL CHANNELLING MACHINES Ltd. lNTERNA'rlONAl CHANNELLING MACHINES L-td.

STABLE HOLES FOR LONGWALL MACHINES. \ l 7HEN working Longwall it is usually an advantage-in fact, VV almost an essential-to keep the ends of the face in advance of the centre. When a Longwall machine is used and the stable holes for the machine are made by hand, it very frequently happens that the stable has not been made wide enough. The result is that t~e machine starts with a shallow cut, getting to its proper depth as 1t proceeds along the face. In this way the ends of the face soon get behind, and all Colliery Managers wi.1~ recognise the trouble that will ensue when the face assumes this concave shape. By using a,., SISKOL" for stable holes the face is kept in proper shape. THE "SISKOL'' COAL-CUTTER 24 25 �lNTERNAT'IONAl CHANNELLING MACHINES L:td l NTERNA'rlONAl CHANNELLING MACHINEJ' Ltd. THE "SISKOL" COAL-CUTTER. HE " SISKOL" can b~ used in_ seams from 18 in~. and upwards in thickness. The 11lustrahon on the opposite page shows such a machine, which has been used successfully on a longwall face in a seam less than half a yard in thickness, with extremely gratifying results. Seven to eight yards can be holed at one fixing, after which it is an easy matter to flit the machine intact when fixed on a sledge or plate. In this way it is possible to hole a place 30 ·yards wide with four settings of the machine, and, as _only a few minutes are needed to loosen the column, flit the machme and reset, practically the whole of the shift can be occupied in cutting.

HE " SISKOL " may be used for other purposes than cutting in coal, as vid enced by the following extracts from the Official report of H. i\'I. Inspector of Min es for th e Card iff district :- T " ROOF RIPPING WITHOUT EXPLOSIVES. - At the Great Western Coll iery Co.' Tymawr Pit thr roof on the roads in one scam i,; ripped down without the a id of explo i\·e . The roof, which is a hard sandy fireclay, 4 ft. thick, is cut or sheared on each side of th e road by a ' Champion ' Channelling Machine. A hole.' is bored near tlw top of the bed and a long plug and feather is inserted and the mass is wedgt:d dmrn, the whole of the work being don e by th e machine, thus showing that the use of explosi\·es can be a\ oided in doing such work . Besides doing a~\'ay with the risk attendant on the use of explosi, es, Mr. Gray is strongly of opinion that roads npped by other means stand very much better than those ripped by explosives." . . . In his evidence bdorc the Royal Commi::;sion on Mines Mr. F. A.
