A plan .of the surface veins of Crich Cliff and in the Private Liberty of Barker's Field, Plaistow Field and Wakebridge ranged out by Mr. W. Frost in October 1834 gives the name Rolley Mine to this shaft, bµt nearly a hundred years later, it ha� become well known locally as the Jingler Mine. Across the highway from Holloway to Crich, to th� east, stand a pair of This is modern dwellings and at the rear are remains of old building.s. It therefore said to be the remains of Rolley's House and close by a shaft. seems reasonable to assume that this in all probability was·Rolley's climbing shaft and that Jingler was the winding shaft for it is said to connect. However, the author having no knowledge of the underground workings of this mine or of its earlier history has had to rely upon local legend. Fortunately, Mr. L. Davenport was able to supply informatipn from memory, of the days when he worked at Jingler, firstly, during school holidays and later on leaving school, when he was employed on the surtace plant and eventually for a short time, underground, at the beginning of the 1930's. There are records that show that Jingler worked from 1927 to 1931, when it finally closed and the number of men working there in 1927 is given as 6 underground and 6 on the surface, by 1928 it had increased to 9 under ground, then 1929 reduced again to 6, but now there were 13 on the surface. In 1930 only 3 employed in the mine and 3 on the surface, then finally in 1931, 4 underground and 6 on the surface. At this point it is interesting to note that Wakebridge No.l was working in 1921 and went on more or less continuously until 1931, when it finally closed. Here also, there was a fluctuation of labour over the years and as both mines were owned by the Derbyshire Fluorspar Company no doubt labour was moved from one to the other as circumstances made necessary. The Jingler Shaft, now covered with a concrete cap, is about three feet in diameter, believed to be ginged with dressed gritstone, it is drained by the Ridgeway ·sough but when last worked the lower levels were In 1931 the shaft descended waterlogged and the true depth is unknown. There seems no 246 feet, it had a false floor below which was water. indication that pumping was necessary and one presumes that the water did . not normally rise above the shaft bottom and drainage by the sough was adequate .. The pitch pine headstocks, standing today, some twenty feet high around the shaft·top, are surmounted by a cast iron wheel 2ft. 6ins. in diameter over which passed the finch steel haulage rope to the cage, which, was similar to the one still in existence at the Glory Mine.

The lower half had a 'V' shaped base, one side hinged and held in place by a catch o This carried the crude ore, which, upon releasing the catch p allowed the door to open and the contents to fall into a box - car on rails positioned beneath the upheld cage and spanning the open sbaft o A cross-timber on the headstock frame just below the wheel supported two 10 mm. steel guide ropes which passed through loops on the sides of the cage and terminated at the shaft bottom 9 they prevented the cage from spinning and held it from swinging or hitting the shaft side. Evidence can be seen on the headstocks of the wire and lever band operated bell signalling system used to communicate between the shaft bottom and the man operatimg the winch hauling the cage o About 15 feet on the south side of the main headstock frame stood the haulage drum which was a unit not uncommon in areas where small mines operated, being a central winding drum driven by two cylinders, positioned one at each side of the drum and powered by steam. There was also the alternative of driving this winch by compressed air 9 useful when a fault occurred or maintenance was being carried out on the steam raising boiler e The whole of the shaft top installations were enclosed within a building mainly of corrugated stael sheets (No o l on plan) with the exception of the upper part of the headstocks, which projected through the roof. Apart from this particular building the main building was the jig shed, built mainly of wood with a wooden boarded roof 9 felt covered, and the sides corrugated sheets upon a timber frame o On the closing of Jingler Mine this shed "Was moved to Golconda where it stands today housing goods awaiting despatch. The other buildings were of the same materials but in the main were erected on the lean-to principle grouped about the jig shed. Power for the winding drum was provided by a coal fired vertical steam raising boiler and this was supplied with town water (J) o The ore-dressing plant was powered by one single cylinder horizontal gas e�ine, said to be about 50 h o P e and cooled by two cylindrical water tanks {2). Both �as (coal gas) and water (marked 14 and 13 on plan} were from the mains {town} supply and the mine office had gas lighting. An adjoining lean-to building (12) housed the compressor, driven directly from the gas engine but details of the machine itself are so far uncertain although it is believed to have been a twin cylinder, crank driven, piston type of compressor operating at about 100 lbs. per square inch, the output in cubic feet per minute unknown o It provided air for Jack Hammers in the mine, i.e. compressed air drilling 9 perhaps even an air winch if inclines were employed o The men would however work mainly with pick, shovel, wheelbarrow and tram haulage o The logwasher (4), 16 feet long, lying in a bed made by itself 16ft. by Jft. was surrounded by a very low gritstone wall to hold the ore. The tail of the log was probably loose, having no bearing as is quite comn.on place, but guided by pieces of wood let into the wall so that should a large stone or piece of bard material get stuck the log would be free to lift and ride over it rather than break something and by its own weight the 60. Do w nl oa de d fro m w w w .p dm hs .c om It was chain driven to prevent slipping. log would maintain its bed. The primary drive was probably taken from the compressor shed (12) to the logwasher and these twos together with the crushing rolls (io) would require considerable power to drive them and belting would slip (Vee belts were not yet common), but transmitting power by belt and pulleys to the jigs and screens would be relatively simple o From the logwasher drive, which had a small rotary screen fixed to its end, power was taken to the cru.shing rolls p the picking belt and to the overhead shafting into ·the main building where belts and pulleys transmitted power to the main battery of five Ji$s each of four bays (5) 9 the lead jig (6), the two concentrating tables (7) and the overhead rotary four panel screen (giving five sizes) (8), then the bucket elevator (9). Jingler Mine at this period, 1920 9 s to J0 9 s 9 was worked mainly for fluorspar, barytes was produced but usually only in small quantities and sent to Golconda for grinding, there was always a varying amount of calcite which was together with any limestone thrown onto the waste tip. Galena The output is unknown for this period, was more or less a by-product. mine records were of course kept but as they are hand written pocket book type, are rather personal and the owners do not wish to release them at this stage. From the shaft top a set of rails carried a small box-car, loaded as This was pushed by band to the logwasher described, from the mine cage. and it's contents shovelled into the 'low end', being below floor level. The spiralling of the washer blades as the ore is first pushed forward, then dropping back to the next blade s to be pushed forward again and each time travelling a little higher up the log troughs gradually breaks up any clay present and the jets of water from above the log continuously flushing dirt and sandy material back to the low end and out to a settling pond, the clean material being pushed gradually over the high end of the log into the rotary screen where lumps pass out of the end onto the picking belt. Two men or boys band sorted the barytes into a wheelbarrow, the limestone and calcite onto the tip whilst the lump fluorspar continued on the belt to fall onto the loading dock via the chute. Meanwhile gravel passing through the screen mesh fell into the crushing rolls was reduced in size, picked up by the bucket elevator, carried into the main building where a rotary screen overhead delivered five sizes to the main jigs by inclined chutes, water propelling the material along. In this process of separation the galena bearing ore was passed along water fed channels to an adjoining lean-to shed where a lead jig removed the galena in several sizes which on 'tapping' the jig s was drawn off into wheelbarrows and stockpiled. The 'fines' were pumped to two concentrating tables and left the tables by small chutes directed into metal boxes which were emptied from time to time onto a 'belland' stockpile. The main jigs were elevated to allo'W small 'Jubilee' type side tipping tru.cks to pass beneath the level of the •tapping plugs'. When full these trucks were pushed by band to the turntable and along the tramway to the second turntable where their contents could be tipped out, down the chute Fluorspar on the loading -·-·�-�:�:!'..ejects were carried, onto the waste tip. · dCJ·ck was band loaded onto horse drawn carts and conveyed to Wbatstandwell 61. w w w .p dm hs .c o m Railway Station, by way of the track downhill to Robin Hood, there to be tipped into goods waggons. Later, motor transport took over and the route was then via the road toward Crich, but turning right down the lane through Coddington and so to Whatstandwell. The Brook, flowing southward from Varker Field, follows the line of the fault for some distance, passing Wakebridge Chimney Shaft or (often referred to as) Wakebridge No.2 then on past Wakebridge No.l with its Engine House and below it passes beneath the road to skirt the Jingler Tip where it gradually turns westward, eventually passing close to disused" gritstone quarries at Robin Hood. From here it flows beneath the road from Holloway to Whatstandwell, to join the Derwent after some water at least, by design or accident, has found its way into the Canal. Although there was only a small dreHing plant at Jingler, a considerable quantity of water would be required. To supply this a dam was bu.ilt just west of the house, formerly the agent's house and office, (when these mines were part of the Nightingale Estate) and to the north of Wakebridge No.I shaft on the brook course. The outlet was a 9" pipe feeding a J" supply line (iron pipes) lying in the brook and following its course beneath the road onto the Jingler site where it was fed into the circuit. Channels in the floor took away the spillage from the jigs, the logwasher slimes passed from the tail of the log and collectively these waters passed through a pipe which was supported on a trestle over the bridle path and brook to settling dams in Oxhay Wood. After depositing the sediment the clear water was allowed to flow back into the brooko de d fro m Acknowledgements Thanks to Mr. L. Davenport of Crich for his invaluable help and to Mrs. P. E.
