Abstract

461,191. Rotary conveyers. CHERRYBURRELL CORPORATION. Aug. 8, 1935, No. 22436. Convention date, Feb. 23. [Class 78 (i)] [Also in Groups XVII and XXII] A rotary conveyer for bottlefilling machines is provided with a plurality of guides for a plurality of bottle supports, each of which is raised vertically with respect to its guide by the co-operation of the support, in the movement of the conveyer, with an adjustable cam, each support being provided with a self-engaging clutch effective releasably to maintain it in the position to which it is raised as determined by the adjusted position of the cam. Empty bottles are transferred by a star-wheel 27 from a conveyer 26 flush with a table 25, Fig. 2, to supports 92 on a rotary turntable 17, Fig. 1, carrying the bottle filling mechanism. Filled bottles are transferred by a star-wheel 29 from the turntable 17 to a capper turntable 19 from which the filled and sealed bottles are moved by a star-wheel 28 on to the conveyer 26. Each bottle support 92, Fig. 3, comprises a tube 91 slidable on a post 90 fixed to the turntable 17, the tube having a roller 99 to engage an adjustable cam 100 during the rotation of the table. This raises the support 92 to carry the bottle into engagement with a filling apparatus, the support being held raised by a friction clutch roller 94 located in an inclined notch 93 in the post 90. When the filled bottle reaches the transfer wheel 29, a spring-pressed rod 95 engages a cam which moves it up to release the roller 94, the support 92 being lowered to its initial level by the roller 99 coacting with a lowering cam 106 on to which it falls by gravity. A complementary cam engaging above the rollers 99 is provided in case the supports stick at the lowering position. The turntables 17, 19 and the transfer wheels 27, 29 are driven by a single endless chain 70 passing round a driving sprocket on the vertical shaft 62 of the star-wheel 28. The shaft 62 is driven by worm gear 60 from a main drive shaft 47. The transfer wheels 27, 29 and the cams 100, 106 are interchangeable so that the apparatus may be adjusted for bottles of different sizes. The Specification as open to inspection under Sect. 91. comprises also the employment of the adjustable supports in a box wrapping machine to lift the box to the wrapping mechanism and in any automatic machine tool to lift the work to-and-from the tool. They may also be employed on any type of con veyer. This subject-matter does not appear in the Specification as accepted.
