Abstract: 681,093. Delivering measured volumes of granular &c. materials. TRIGG, W. W. (Maryland Plastics, Inc.). Nov. 19, 1948 No. 30168/48.. Class 106 (v) [Also in Group V] In a machine for moulding buttons and other small articles (see Group , V), moulding material in a hopper 10 is delivered in measured quantities into cavities 29 in a plate 30 which then' moves to dump the material into moulding recesses 69. The material falls from the hopper 10 into a row of openings 14 in a rotatable measuring device 13. Four sets of openings 14 are provided, presentable successively to the hopper by intermittent rotation of the device 13 by pawl and ratchet motion driven by a motor 33 through worm gearing and a cam on the shaft 36. The bottoms of the openings 14 are closed by plungers 15 provided with toothed racks engaged by elongated pinions 18 to which partial rotary motion is imparted as the device 13 rotates by levers secured to the pinions and carrying cam followers engaging in a fixed cam groove. The cam groove is arranged to withdraw the plungers 15 in the openings 14, when these are immediately below the hopper, to an extent such that the openings are overfilled. The plungers then move back to the correct distance, which is adjustable, and surplus is removed by the edge of the hopper as the device 13 rotates. The cam groove may also be arranged to provide posf-. tive ejection of the material when the openings 14 reach the inverted position over a set of shoots 27. In this position each batch of powder falls or is ejected through a separate shoot 27 into one of a . row of cavities 29 in the transfer plate 30. The plate 30 has three rows of openings which are successively filled by appropriately tilting the shoots 27 by means of a cam 38 on shaft 36 acting through follower 39 and levers 41, 42.

Abstract: 1,017,581. Severing by tearing. CELANESE CORPORATION OF AMERICA. Aug. 8, 1962 [Aug. 9, 1961], No. 30288/62. Heading B4B. A method of converting a continuous length of cellulose triacetate plastic sheet material into two or more continuous narrower strips comprises forming at one end of the material short lengths of the narrower strips and then pulling the strips forward in different directions so as to tear the material while maintaining substantially stationary in space the point or points where the material separates into narrower strips. As shown, plastic sheet material 10 is passed over a roller 20 to a severance point 12 and the tearing of the material is carried out by pulling the edge trim 14 over a roller 18 so that it follows a path inclined to that followed by the trimmed stock 16. A tear block 22 mounted on a shaft 24 assists in avoiding lateral displacement of the point 12 and a pressure pin 25 assists in maintaining the edge trim 14 in the desired position. A roller similar to the roller 18 may be provided to engage the trim from the opposite edge of the film. To ensure that the or each tear follows a straight line, the untorn sheet material can be provided initially with a straight guide line which is conveniently a groove in a knurled edge 28.
