Abstract: 389,465. Gramophones combined with coin-freed weighing-machines. SPINKS, L., 196, Clarence Gate Gardens, Regent's Park, London. Sept. 7, 1931, Nos. 25112/31 and 8002/32. [Class 40 (ii).] A coin-freed weighing-machine of the kind wherein the scale levers, supporting the platform, are mounted on a base which hinges downwardly a predetermined amount each time a person stands on the platform so as to set the weighing and ticket-printing mechanism, is characterized by the provision of a gramophone attachment which is brought into operation by the weighing and/or ticket printing or release mechanism, the turntable being driven by a spring motor which is wound automatically by means operated by the said base. When a person steps on a platform 24, Fig. 1, supported by lever mechanism 25, the base 15 pivots about axles 16 and a projection 20 tilts a lever 21. This lever raises a rod 29 against the action of springs 30 and through a rod 34 and sleeve 35, Figs. 3a and 4a, tilts a lever 33 so that a projection 38 thereon is engaged by a detent 39 on a plate 40. A rod 26, connected to the platform 24, simultaneously moves down against the action of springs 41, connected thereto by rods 43, and, through links 50, 51, and a bar 42, pulls down a rack 46 meshing with a pinion 47 on the spindle 48 of the weight wheel 49. A coin inserted in a slot 58 trips a lever 59, pivoted at 60, which through a tooth 61, withdraws a projection on a lever 62 from a recess in a bar 63 depending from a lever 64 rigidly connected to an arm 65. When the bar falls, the printing hammer 66 is actuated through links 67, 68 and registers the weight on a blank ticket previously positioned on the weight wheel. Simultaneous with the downward movement of the hammer 66, a spring tooth 95 on an extension 94 is moved rearwardly across the bottom of the ticket magazine so that during- its return movement it feeds the lowest ticket forward to a slide, the printed ticket then being thrust from the slide into a delivery shoot. A. roller 69 on the lever 64 simultaneously actuates a pawl 70 and releases a lever 71 which is tilted by a spring 72 and, through a projection 73, engages the plate 40 to release the lever 33, which together with the lever 71, is returned to its normal position when the person steps off the platform. An extension 34a of the rod 34 is connected through links 76, 77 to a lever 78, Figs. 3a and 6, carrying a pawl 79 which rotates a ratchet wheel 80 one tooth, each time the rod is raised, to rewind the gramophone motor 83 geared to the spindle 81. A spring 84, between two parts of the link 77, prevents overwinding of the motor. The gramophone turntable 176, Fig. 4a, normally held by adetent 179 on a frame 177, is released when the frame is moved longitudinally by tooth 182 engaging a bar 183 on the frame. This tooth is mounted on an arm 181 which is actuated through a member 85 by'the ticketprinting mechanism. The frame is returned by a curved cam 140 on the turntable engaging a roller 141 on the frame. A pinion 89, Figs. 3a and 6, meshing with a rack 90 on the frame, rotates a cam 87, engaging a fixed cam 88 and raises the turntable into contact with the needle of the tone arm. The adjustment of the tone arm 97 across the record in accordance with the weight of the person is effected by a cam 98, Figs. 3a and 7, on the spindle 48. This cam is engaged by a roller 100 on a lever 101 which is supported by a shaft 102 on which is adjustably mounted a slotted arm 103 engaging a roller 104 on a lever 105 connected to the tone arm mounting 106. The tone arm is held in its adjusted position by a spring- controlled brake shoe 108 engaging the milled periphery of a brake wheel 107, the shoe being normally held inoperative by a lever 110 engaging the re-setting lever 71, but is released when this is tilted upon insertion of a coin. If the announcement of the weight is not desired, the coin is inserted in a shoot 117, Fig. 4a, and operates a lever 118 which engages a pin 128 on a lever 127, Figs. 4a and 8, and raises a weighted plate 125 so that a slot 129 aligns with a pin 124 on a rod 123. When the rod falls, it raises the arm 181 through a lever 120 and prevents the tooth 182 engaging the bar 183. The mechanism is reset when a person steps off the platform by a collar 130 engaging a lever 132, the plate 125 then returning to its normal position, Fig. 8, in which it supports the rod 123. A bar 133, Fig. 10, detachably connected to the base 19 of the machine by split pins 137, is provided with adjustable feet 134 for levelling the machine.
