Title: Improvements in or relating to machines for making pneumatic tyre covers or casings
IPC: B29D30/16
Filed: 1920-01-03
Abstract: 160,032. Dunlop Rubber Co., Ltd., and Macbeth, C. Jan. 3, 1920. Tyre covers, making.- In a machine for making tyre covers, braking-means are employed in connection with the stretching-gear to ensure the proper tensioning of the first end of a fabric ply in its application to the core, such means being automatically disengaged after a predetermined movement of the core. In the constructions shown, a ratchet-wheel H or. the shaft B<1> of the stretching-roll B is engaged by a spring-loaded or weighted pawl E which acts to retard the shaft B<1> until the pawl has moved to a position wherein the springs or weights effect its disengagement from the ratchet. Referring to Figs. 2. 3, 4, and 5 the pawl E is slidably mounted' in a bracket F pivoted at F' to the machine frame, coil springs being fitted between a collar E<1> on the pawl and the further flanged end of the bracket. As the fabric ply D, with or without a short leader-strop D<x>, is pulled on to the core A, the reaction between the ratchet H and pawl E causes the bracket F to turn on its pivot F<1> until, in the position shown in Fig. 3, the pawl is disengaged. The frame F, when thus released, swings sharply and Fig. 4 shows a trip-mechanism for arresting the frame and holding it in a position ready for further operative engagement with the ratchet. A weighted rocker K, normally depressed by the fabric strip D, has a pin-and-slot connection with a link K<2> pivoted to a sliding bolt K<1> on the frame. As the bracket F swings away from the ratchet H, it is tripped between a pair of detents K<5>, K<6> pivoted on the bolt When next the fabric strip D is released, the rocker K swings on its pivot to the position shown in dotted lines in Fig. 4, the sliding movement of the bolt K<1> effecting the release of the detent K<6> and the bracket F, which is then free to engage the ratchet. In modifications, the pawl E is pivoted to, or has a toothed engagement with, a weighted lever. Figs. 8 and 11 illustrate further modifications in which the retarding-pawl E is pivoted to a weighted lever.
