Springs are ExpendnPERATORS who cornable but Their Life %." plain about spring break May Vary ages were reminded by Mr.
J. A. Birdsell, B.Sc., A.M.1.Mech.E., design engineer of Jonas Woodhe.ad and Sons, Ltd, in the discussion following his paper on springs, read recently before the Institute of Road Transport Engineers, that they must look upon springs as being expendable. They should therefore have no grievance unless fractures occur too frequently or at too small a mileage. Failures may, of course, be more frequent if springs which are not intended to be lubricated be treated in this manner and thereby caused to work too freely. If others, designed for lubrication, be neglected and become excessively stiff, trouble in other directions may result.. It seems, however, that the main cause of fracture is failure to keep the spring bolts really tight. This applies particularly to those types the leaves of which have a central hole. Loose bolts permit a concentration of stress at the holes, and the leaves may break individually until sagging or complete failure occurs. Cracks often start at the lowest leaf and work through consecutively.

Training Scheme Run WE have referred previously by Associated Bus " to the training scheme run Companies . . : . by those bus companies under
the xgis of the British Electric Traction Co., Ltd. This is to produce qualified men for the higher posts in the companies concerned. Last year three trainees who had completed the course were appointed to such positions, and recently two more have been placed—P. C. Hunt as assistant to the traffic manager of the Southdown concern, and J. H. Richardson to a post in the traffic department of Devon General. The first was released from the Navy with the rank of Lieut. (R.N.V.R.), and was accepted for training, being posted to the Midland " Red " in November, 1946. The other was an engineering student at Cardiff Technical College, who completed the first stage of training for the higher national certificate, but joined the Forces, and was released towards the end of 1946, with the rank of captain. He went to the Northern General Company for his course. This indicates the attention to training which important private-enterprise concerns are giving in this urgent matter of providing suitable executives.
