Abstract
555,553. Engine indicators. ELECTROFLO METERS CO., Ltd., and TABOR, H. June 18, 1942, No. 8362. [Classes 106 (ii) and 106 (iv)] The link-work between the pressure-operated element and the recording pen or indicating pointer is provided with ball-and socket joints at all first points. The link-mechanism is supported on a head 5 which can be swung about the axis of the piston 1 to bring the pen into or out of contact with the record sheet. The upper arms 9, 10 on the head provide bearings for a pair of swinging side plates 11, 12 to the lower ends of which a U-shaped member 13 carrying the pointer 4 is pivotally connected. The side plates 11, 12 are arranged adjacent the arms 9, 10 to form a unitary structure braced by connecting tie rods 14, 15 disposed one at each side of the piston 1. The pivotal connection between this structure and the head 5 is formed by two balls 16, 17 between the inner surfaces of the plates and the arms, the balls being accommodated in recesses or holes in the arms and plates. At their lower ends, the plates are connected to the U-shaped member 13 similarly by a pair of balls 18. By tightening the nuts on rods 14, 15 any play may be taken up. A forward projecting part 20 attached to the piston 1 affords pivotal supports for a unitary structure comprising more or less vertical links 21, 22 connected by tie rods 23, 24. The pivotal connections are by balls 25, 26 between the inner faces of the links and the part 20. The lower ends of the links 21, 22 have ball and socket joints 28, 29 between them and the inner surfaces of the member 13. Play is taken up by the rod 23 and a tie rod 30 between the limbs of member 13. A final stirrup member 32 has ball-joint connections 37, 38 with a member 34 extending upwards from the base of the head 5 and also first connection with the links 21, 22 by balls and sockets 39, 40. An elliptical or substantially elliptical spring is interposed between the piston and a fixture. Abutments centrally located on the spring prevent the spring being over-stressed.
