Wheel Alignment by Projection
CLAIMED to be the only one of its kind in this country where direct readings are made, the BEM projectiontype wheel-aligning eouinment now available from Morris and Ingram (London), Ltd.; 25 Victoria Street, London, S.W.I, can be used by comparatively unskilled labour.
A light-beam unit is carried on a swivel bracket located on the wheel rim of a vehicle at three points. By projection of the beam on to scales, the wheel run-out can be checked, together with chassis longitudinal alignment, camber, caster, king-pin inclination, toe-in and toe-out, rear-axle alignment and turning-radius angle.
Stiffer Aluminium Sheet ARECENT addition to the range of aluminium sheeting produced by the Northern Aluminium Co., Ltd., Banbury; Oxon, is Noral thin-gauge shallowtroughed sheet_ It is suitable for many panelling applications where flat sheet was previously used. Besides its decorative value it provides greater stiffness.
The troughs are I in. wide and depressed -ea in. at pitches of 2 in., 3 in., 4 in. or 6 in. Edges parallel to the corrugations have borders sufficiently wide to provide a I in. overlap, also affording a continuous symmetrical pattern across joined sheets.. The overlap can be used for a variety of fixing methods, and gives standard effective sheet widths of 36 in. and 48 in. Both transverse and longitudinal Corrugations are available, either on plain or stucco finish sheet.
Tractor Shovels Announced
THREE tractor shovels, the BL.440,, the
BL.450 and the BL.450T have been announced by W. E. Bray and Co., Ltd., Faggs Road, Feltham, Middx. The same main frames, axles and hydraulic systems are used for all the models, which have rear-wheel steering giving a turning radius of under 20 ft. to the bucket end.
Powered by a Ford four-cylindered oil engine, the BL.440 has a lifting capacity of 2,800 lb., whilst the BL.450 and BL,450T both have a Perkins 62-b.h.p, oil engine and a lifting capacity of 3,100 lb, A conventional-type transmission is employed on the BL.440 and BL.450 machines, and gives six forward a22
and two reverse gears. Speed range is from 2 to 13 m.p.h.
A Brockhousc torque converter is installed in the BL.450T, and operates in conjunction with a hydraulically operated cpicyclic gear providing two forward and one reverse speeds.
Epicyctic gear hub reduction units are fitted on all axles, which have equal-sized tyres. Power-assisted steering is standard, and the controls are grouped conveniently for the driver, who has an unobstructed view of the leading edge of the bucket while digging.
