Description of Test Load Design.
The sender of the following commitn,ication has been awarded the extra payment of os. this week. [2,213] " B.W.H." (Venissieux, France) writes:— " Having read with much interest the article entitled 'Loading for Road Testing' by Vim,' I put forward the following suggestion for loading for testing. If would add that I used this system with much success for testing lorry chassis during the war.
'The case (K) is strongly constructed of wood and is divided into three or more compartments. In each of these compartments are placed plates (A) of a known weight. Each plate has a hand hole (a) cut in it to facilitateremoval from the case, and when in position the plates are prevented from jolting out by an iron bar passing through these hand holes, and bolted to the sides of the case.
a The case itself stands on two legs (EE), which should be made to the average width of the chassis members of the types of vehicIesFmost usually to be tested. When it is desired to test a bare chassis the case can be bolted to the chassis frame by means of the tr-bolts (D). For use when testing the complete lorry and body, the IT-bolts can be removed and the case allowed to stand on its own legs. The rings (0 (1) are provided to enable the case to be slung off and on to the chassis or vehicle by means of an overhead derrick. "It will be found most convenient to make two cases about 4 ft. square, each one to carry,. say, 2i tons, making a total of 6 tons. The twoeeases should be bolted to the chassis one behind the other, so that the load is distributed the full length of the frame. It will be understood that as the plates are removable, any weight of load can be made
Fitting a Clutch Stop.
[2,214] " F.B." (Croydon) writes :—"We have an old type 40 h.p. motor pump which used to be rather difficult to manipulate owing to the fact that the clutch was not fitted • with a. brake or stop. This made it very,cliffieult either to start the chassis or to change speed when in motion. I managed to overcame the difficulty) as described in the following notes, and illustrated by the accompanying sketch. " The clutch is of the inverted cone type, the driven member being of pressed steel. Procuring a. piece of steel plate 3-16 in. thick and 10 ins. diameter, I cut is hole in thia so that it would slip over the universal joint and riveted it to the clutch member, the shape of which was such that a portion of the plate on the forward side was left exposed ,when it was riveted in position. (See sketch.) I then cut a couple of fingers from in. steel plate. I made them I in. wide4•and bent them at one end so that they.could be bolted to clip on to the pedal shaft. At the other end I padded them with leather. I set them upon a clutch shaft so that when the clutch was completely engaged they were just clear of the inner face of the new plate which I had fitted. When any movement was made to disengage the clutch, therefore, this -elate came in contact with the fingers, which made a most effective clutch stop."
