TWO ingenious ideas, one for a i thief-proof device, and the other for stopping window rattles, have been suggested to "The Commercial Motor" by Mr. T. Moxon, Upper House Cottage, Denby, near Huddersfield.
The thief-proof device works on the principle that when the door of the • DOOR(C1.05ED)
vehicle is opened by an unauthorized person the horn circuit is completed and the horn cannot be stopped because the door cannot be closed.
The device consists of a spring. loaded ball which is let into the door pillar. One, of the accompanying sketches shows how the ball and its
spring are assembled. To prevent the ball from making contact with its cover plate, a piece of rubber is secured to the door edge so as to line up with the ball. This has the effect of pushing the ball away from its cover plate.
A second drawing shows the simple fitment which prevents the door from being closed after it has once been opened by a potential thief. It amounts to a spring-loaded stop which comes out to obstruct the passage of the door.
Simplicity is again the key-note of Mr. Moxon's anti-rattle device. He secures a piece of inner tube to the window frame adjacent to the glass and this, he says, not only stops the window rattling, but steadies its up-anddown movement.
Another reader, Mr. Jack Newman, 51a, London Road, Forest Hilt, London, S.E.23, puts forward an idea
which he suggests is an improvement on the " organ" accelerator pedal fitted to some makes of commercial vehicle. In the present instance it is intended for application to the Dennis Pax.
The existing pedal is cut away to take a roller, which may be of mild steel, mounted on either a through bolt, or on two separate bolts screwed into end supports. The accompanying drawing shows the idea as carried out by our correspondent.
The advantages claimed are reduced wear on the soles of boots or shoes, and greater comfort during long spells of driving.
