Abstract
142,484. Kuhn, G., (Assignee of Kuhn, P.). July 10, 1918, [Convention date]. Void [Published under Sect. 91 of the Act]. Extrusion machines. - Relates to extrusion presses with a moving core or cores for making hollow blocks closed on all sides, and consists in freely mounting the core or cores within the press head. As shown in Figs. 1 and 2, the core 3 is supported by arms extending laterally through slots 5<c> in the head 1, such arms being connected to racks 12 meshing with sectors 39 mounted on a shaft 32. The arms are apertured at g for the passage of air from pipes h to the interior 4 of the core, such air passing through valves 6 to the interior of the blocks during the formation of the hollow portions. The pipes h are fitted with valves R which are opened and closed by contacting with fixed stops 10, 9. Springs 7 close the valves 6. To prevent adhesion, the core is faced with gypsum &c. 15. Fig. 6 shows a modification in which the cores are mounted on arms 40 secured to shafts 41 operated through a crank and levers. Instead of admitting air through the cores, the stroke of the cores may be adjusted so as to prevent complete closure and allow air to enter through the stream of connected blocks.
