A Show-Time Production Which Should Help in the Carrying Out of the Principles Enunciated in the Foregoing Article. ,
THE editorial staff of The Commercial Motor has collafiorated with the solid tyre department of the Dunlop Rubber Co., Ltd., in devising the At-a-Glance Efficiency Chart for the use of owners of commercial vehicles, fleet managers, and foremen. A full-size specimen (9i ins. by si ins.) will appear in the next issue of The Commercial Motor, with full explanatory text, the same information being published in a booklet dealing with solid tyres which is being issued by the Dunlop -Rubber Co., Ltd.
. It is our intention to place copies of this chart on sale at the Commercial Vehicle Show and thereafter at 8s. per 100, 4s per 50, or 2s. per 25 post free. They will at first he supplied in a loose form and, as each sheet will accommodate the records of eight vehicles over a distance of 500 miles, half a dozen sheets will carry the records of a small fleet for a few weeks—sufficiently long for the simplicity of the, scheme and the value of the records to be adequately tested. • We also propose to issue the forms bound in groups of such numbers as are required, and it is suggested that, if it be found more convenient for the fecording staff to work on the loose sheets, the latter when completed can' be kept in a file and afterwards bound in a cheap form of binding should it be desired to make the record a permanent one. Our own opinion is that the record should be regarded as permanent, for its value must expand as the record itself grows.
Sonic fleet managers may care to keep the record in duplicate, the second copy being pasted on a card and hung in the office of the fleet manager or of the foreman, where it can be on view to each member of the staff and serve as an incentive to better results.
The records for which space is provided on the chart in respect of every vehicle are :— (1) The mileage covered.
(2) The consumption Of fuel. (3) The consumption of _oil.
(4) The expenditure on repairs.
(6) The expenditure' on tyre replacement. •
From (2) to (5), consumption and cost, are all in relation to (I), or the mileage covered, and the chart is so devised that, for each individual vehicle, its standard consumption and expenditure are taken as the basis, any falling away or any improvement being visible at a glance (from which fact the chart derives its name).
