1,012,359. Recording-apparatus; speedometers. KIENZLE APPARATE G.m.b.H. April 24, 1964 [April 26, 1963], No. 17070/64. Headings G1K and G1J. Recording-apparatus comprises a record disc support 55 driven by clockwork 56 and a coupling sleeve 46 with a centring pin 63 and drive pin 52 co-operating with openings 53, 54 in a record disc 14 and in the support 55 when a lever 21 is lowered. To insert a new disc 14, the lever 21 is held in raised position by a nose 33 or pin 34 thereon resting in a high notch 38 in a cam 35, the disc 14. is pushed through a slot in the case 43 until it touches a stop 61, a disc 36 is turned manually by means of a knurled part of its periphery and the pin 34 slides down a slope 39 of the cam 35 until the pin 63 enters openings 53 in disc 14 and support 55, with pin 52 resting on the disc 14. A toothed part 44 of disc 36 now meshes with a toothed wheel 45 frictionally coupled to the sleeve 46 so that further turning of the disc 36 causes the sleeve 46 to turn relative to the disc 14. When the pin 52 enters the opening 54 of the disc 14, the disc is carried round until the pin 52 also enters the opening 54 in the support 55. The disc is now positioned correctly for the time of day, the wheel 45 ceases to mesh with the teeth 44 and further turning of the disc 36 does not affect the coupling sleeve 46. Styli 13, 30 and 18 are mounted and guided so as to be raised and lowered by the lever 21. The support 55 bears time graduations viewed through a transparent shield 60 provided to prevent tampering with the time mechanism. Warning lights, interlocks and ejection mechanism for the disc 14 may also be provided. The apparatus may be used on a vehicle to record speed, distance and rest or motion. The drive connection 57 between the clockwork 56 and disc support 55 may be a toothed wheel and toothed rim. Specification 1,012,358 is referred to. |
