Title: Improvements in or relating to record changing devices
IPC: G11B17/16
Filed: 1947-07-30
Abstract: 640,378. Automatic gramophones. MILLER, W., and MORRISON, J. L. D. July 30, 1947, No. 20583. [Class 40 (ii)] In a magazine gramophone the pick-up arm is automatically set relative to the supporting shaft in one of two alternative positions according to whether a 10 inch or 12 inch diameter record is to be played, the setting normally being that for a 10 inch record, and the pick-up provided with a trip-lever which is operated by a 12 inch record when falling to the turntable whereby the pick-up arm is released to swing outwardly to the setting for a 12 inch record. The pick-up arm shaft 14, which is rotated by a control mechanism (not shown), has a sleeve 13 secured to it by a screw 15. A downwardly-extending part of a plate 12 carrying the pick-up arm 10 pivoted on a pin 11 surrounds, and is movable in relation to, the sleeve 13. A collar 20 having an arm 25 is secured to the upper part of the sleeve 13 by screws 21, 22 which may be adjusted to obtain the correct angular relationship between the sleeve 13 and the arm 25. The arm 25 is held in correct relationship with the plate 12 for a, 10 inch record by means of a bell-crank 27 mounted on the plate 12 and having an end 29 which is held in a notch 41 in the arm 25 under the tension of a spring 31. When the mechanism returns the pick-up arm by means of the shaft 14 to its outermost position the plate 12 is brought to a stop by a tongue 19 thereon which bears on a fixed part of the support, but the shaft 14, sleeve' 13 and arm 25 continue to turn a few more degrees. In the event of a 12 inch record being released to fall to the turntable, the edge of said record strikes a lever 39 which lifts a cam 32 and moves the bell-crank 27 out of engagement with the notch 41. The cam 32 has a step 34 under which the bell-crank 27 is latched under the tension of a spring 30 until the pick-up arm shaft 14 is rotated to move the pick-up inwardly over the record. The bell-crank 27 is then moved counterclockwise by the surface 42 on the arm 25 and is withdrawn from beneath the step 34 of the cam 32 which returns to its normal position under the control of a spring 37 acting between a fixed pin 38 and a projection 35 on the cam 32. The new position of the bell-crank 27 permits the plate 12 and pick-up arm 10 to be moved counterclockwise with regard to the arm 25 and shaft 14 under the influence of spring 31 so that the pick-up arm 10 is moved outwardly in relation to the shaft 14 so that the stylus rests over the start of a 12 inch record. When the mechanism again moves the pick-up arm outwardly, the plate 12 is again brought to a stop by the tongue 19 while the shaft 14 continues to rotate a few degrees more. When this occurs the arm 29 of the bell-crank 27 again engages the notch 41 in the 10 inch position.
