Abstract

456,577. Speed indicators. AVERY, W. L., The Blue House, Thorley, Bishop's Stortford, Hertfordshire. April 11, 1935, No. 11216. [Class 106 (iii)] A reed device for giving an audible warning when the engine of a motor vehicle reaches a predetermined speed comprises a vibrating steel strip 3 which is responsive to an electromagnet 2 connected in the vehicle ignition circuit 1 and is adapted to vibrate with a buzzer effect only at the frequency corresponding to the predetermined engine speed. An additional reed 3a tuned to be set in motion at a lower speed may give a preliminary warning. The free length of the reeds is adjusted by screws 9 and a clamping plate 8. Fig. 3, shows an adjustable block 6 for adjusting the effective length of the strip 3, while Fig. 4 shows a device for varying the distance of the strip 3 from the electromagnet 2, comprising a base 15 turnable about a pivot 18 by rotating an eccentric head 20, the free length of the strip being adjusted by the use of a tapered stud 12 to release a clamp.
