Interesting New Tools and Accessories Designed to Serve Various Profitable Purposes
An Ingenious New Bonnet Fastener.
A"
,W addition to the range of fittings made by Amal, Ltd., Holford Works, Perry Barr, Birmingham, is a bonnet clip for commercial and other vehicles, It is extremely simple to operate, is composed of few parts, would appear to be effective in action and employs an ingenious mechanism. As can be seen from the accompanying drawing, the spring serves a double purpose. During the first quarter of a turn of the knob to the operator's
right, it acts as a link between the short lever on the rotating spindle and the hook slide, whilst during the remainder of the movement of the knob it is compressed as a spring, so that the slide is then held up by its pressure. The toggle principle employed enables the spring to be compressed without appreciable effort, and an equally effortless left turn of the knob releases the fastener.
When in action the hook firmly holds the bonnet against the catch, the compressed spring preventing rattle and the possibility of its coming loose. The Amal fastener is easy to fit and only the knob is normally visible.
