Elevator control.

Hi all...The control column fork opperates a horizontal "Torque-tube" and on the ends of this , (after having passed out through the body fabric sides ), two levers actuate the control to the elevator via cables......The cross tube is reinforced at the centre by the "above-shown" sleeve , which incorporates at its centre , integral bosses at the pivot point.....This sleeve is of High Tensile steel..machined on the lathe , leaving an excess at the middle , which was filed down by hand to form the bosses either side which accept the H.T. steel through bolt / pivot , which connects it to the controle column fork.......At the ends , are fitted sockets of HT steel (S96) which incorporate a Splined Shaft...and this carries the matching Internaly Splined Flanges , to which are riveted the sheet metal levers.........The socket-shaft parts like the previously mentioned central sleeve , fit over the 16swg spec 24 (T45/4130 is equivalent ) steel tube cross shaft to which they are taper pinned and sweat/soldered.........The whole assembly is carried on Self Alligning ball bearings , within Dural machined and fabricated housings.....These straddle the lower longerons , fitting via small "wedge" pieces of ash which bring the faces of the longerons from the taper of the body , back to a true parallel , fore and aft , localy , for the attachement of the latter .........There are also short spacer / dust shields which may be seen in earlier "general" photos ......JM

These bearing housings are double sided and Assymetrical , but threaded at both ends for the lock rings.......They are fitted "handedly" in the machine , such that the bearing on ONE side posatively locates the cross shaft assembly in the horizontal loading direction , while at the other end , the bearing is free to some extent , to make allowances for any relative movement of the airframe in this direction.....Both the ball bearings are double row and self alligning..Ransom & Marsdon......JM
