Abstract: 460,661. Feeding like articles in succession. DUNLOP RUBBER CO., Ltd., WILLSHAW, H., and NORCROSS, T. July 1, 1935, No. 18736. [Class 78 (i)] Apparatus for the automatic feeding or delivery of objects such as balls 3, one at a time at each of any number of delivery points, comprises a fixed gravity runway 2 feeding to an oscillating platform or runway 4, 6 mounted on a continuously-rocking horizontal shaft 5, the platform 4, 6 in one extreme position, shown in Fig. 2, allowing a ball to pass from the fixed runway on to the runway part 6 of the platform against an end stop 10, while in the other extreme position, shown in Fig. 3, the platform 4 acts as a stop for the end of the fixed runway and delivers the ball already on the platform, the platform runway being formed as spring-controlled arms 6 which are expanded by a fixed cam plate 7 as the arms are rocked downwards with the platform. The feed to the rocking platform is further controlled by members 11, 14 so as to deliver one ball at a time, 14 being fixed to the platform 4 and 11 being pivoted on the shaft 5, weighted at 12, and operated by a pin 13 on the platform 4. In the construction shown a number of rocking platforms 4, each opposite a fixed runway 2, are fixed on a single shaft 5 which is rocked by means of a lever 19 and linkage 16 from a machine (not shown) incorporating an intermittently-travelling conveyer provided with supports 9 for the golf balls 3. In the position shown in Fig. 2 a ball 3 is on the platform runway 6 and the last ball on the fixed runway is held by the wire stop 11. As the platform moves to the position shown in Fig. 3, the arms 6 are opened by the plate 7 to allow the ball to drop on to the conveyer part 9, the stop 14 rises and holds back the second ball on the fixed runway, and the stop 11 rises and allows the first ball on the fixed runway to move on against the stop 4a which is part of the platform and has also risen. The stop 11 rises only when the pin 13 on the platform 4 comes in contact with it, so that this stop rises later than 14 and 4a. The stop 14, and a spring 15 also carried by the platform 4, assist in separating the balls on the fixed runway 2 if they are liable to stick together. For the same purpose a hammer or hammers actuated from the machine drive may deliver intermittent blows on the fixed runway.
