James..[and Reedy..],when I was very young,about 8 or 9 years old,and throughout the 1950's,and living in Hollymount Square,every night at the same time,approximately 9-0pm,we used to hear a thump from the floor..accompanied by a rattle of window panes,an I was learn't by my miner father that it would have been the caunchmen firing the caunch down.
As I grew older and went into night shift..[5-0pm start] at the Bedlington Aad pit,it made sense to me why it was usually the same time every night...just how the cycle of operations used ti gaan,in the days of hand-filled coal faces.
The AB arc-shearer in the pic was wat we used at the high main/main coal seam at the Aad pit,only they didn't have the cable reels attahed..it was aal muscle power howking cables aroond!
One thing that impressed me was the absolute ultimate piece of engineering underground,and the most underrated,and took for granted,bit of gear.....was the "Combined-heads" at the front of the machine to which the cutting jib was mounted upon.
Whoever designed the heads,must have had a gud heedpiece on thasell's!
If you could have seen these heads with the access plates off,exposing the multi-action sets of gearing...spur..helical..double-helical...worm and pinion..clutches here and there,all gears and head controls operated by one multi-position "Handle"...this guy didn't get a knighthood for this machine design..a bet..,but it was ivry bit as ingenious as putting an engine /gearbox/transmission unit in a minicar!!...come ti think of it..VIC..!..Did ye work on these machines at the workshops?
The jib could be rotated on it's spindle through 360 degrees,slewed nearly 250 degrees,lifted from nearly [but not fully] ground level,to a height which was above the height of the body of the machine,to be used as a "Top-cutter"..it would have been great to be able to have a demo video done in the workshops,with gud lighting,to show the capabilities of this amazing machine...we used to balance 15feet long x 8"x6" straight steel girders on the jib after "waffling " a full cut of coal in a 10foot high seam,and slew the jib in a vertical configuration,very slowly,to lift the girders against the roof,leaving us to put the "Enders" [end props] in at each side of the gateway.
It could also cut vertically,so you could cut the face with a conventional undercut,then cut the face at the centre of the winnings,floor to roof,so creating a "T" cut,the idea being that you fire the left side first,then the right sideand so reducing the blast effect,by using less "Pooda"-explosives,because of having more free faces to fire off.
Mind,these were no ordinary "pit -props"..!,they were 10-feet long x 1 foot thick ,virtual telegraph poles cut to length!
We used to use the machine as a haulage engine to pull the conveyor belt boxend in,during belt extensions,as well as other heavy tasks,to save on muscle-power!!
We had a saying underground..."ye divvent use these...[biceps flexed like Popeye!]...when ye can use these..[pointing ti wa heed!.."]
Pit folklore had it that one of thi lads at thi Aad pit was caught by the Manager cutting he's Initials inti the 10-feet high coalface,the machine was that versatile that Aa cud have cut my Logo WA [with the A spliced over the W],with ease!!...like the AB logo on the side of this machine!
This looks like a 10-foot long jib,so this machine would cut a gateway 24-feet wide in one slew,and the picks are set up to cut from right -to-left.
