IN our issue of November 6th we published a letter by a correspondent, " C.T.Y.," in the page which is devoted to the suggestions of drivers and mechanics. Hehadhad trouble owing to the springs of a vehicle shearing the small central bolt and shifting lengthwise; to prevent this from happening in the future our correspondent had improvised a means whereby he claims to have overcome the difficulty. We are glad to learn from Carrimore Six Wheelers Ltd., that this company has adopted a means whereby such movement of the spring leaves is rendered impossible.
The section view shows that each leaf of the spring is formed with a dome on one side and a corresponding recess on the other side, whilst the clip that holds them together has a dome formed on it which can engage in the recess on the lowest leaf, whilst the top plate has a recess which mates with the projection on the uppermost leaf.
By this means the spring is held together by the clip and the top plate, even while not in place in the chassis. When on its bed, the clip sinks into a recess formed for its reception and is held down by the four bolts shown. It will be seen that the top and bottom plate are both chamfered, so that the actual amount of the spring which is held is not longer than is necessary, thus allowing more freedom of play in the leaves.
B48 We are glad to see that attention has been given to this point, as the usual plan, with its small bolt, was far from being satisfactory.
