Abstract: 357,771. Boot-making machines. WADE, H., 111, Hatton Garden, London. -(Maschinenfabrik Moenus Akt.-Ges.; 33, Solmsstrasse, Frankfdrt-on-M ain, Germany.) Sept. 22, 1930, No. 28313. [Class 17 (i.] Pounding-up.-Relates to shoe pounding-up machines of the kind having a rotating carrier comprising a plurality of independent beating members mounted on the carrier, a reciprocating beating tool adjacent to the carrier, and means for supporting the shoe, and consists in the provision of means for automatically moving the supporting means while the shoe is operated on. The rotating carrier comprises a plurality of beating rings loosely mounted on the periphery of the carrier for movement radially thereof by centrifugal force, the diameter of the rings decreasing from the middle to either side of the carrier. The reciprocating beating tool is arranged to yield in a path around the carrier. The shoe support comprises a toe post 61, Fig. 1, and a heel post 61<1> vertically adjustable by a hand-wheel 64. These members are carried by a plate resting on a pneumatic tube or on springs in a casing 60 arranged to slide horizontally in guides supported by a vertical sleeve 52. This sleeve is vertically adjustable by a hand-wheel 54, and moves with a pinion 32. For raising and lowering the sleeve 52 during operation on a shoe, a sleeve 50 has threaded engagement with a fixed bush 51. This sleeve is rotated by a pin on 31. For traversing the casing 60, this is provided with a rack engaged by a pinion 58 on a shaft rotated By a pinion 33. The three pinions 31, 32, 33 gear with segments such as 28, Fig. 2, pivoted at 27 and connected by a link 40 with a lever 39 actuated by a link 37 pivoted to a cam-operated lever 24. The connection between the link 40 and the lever 39 is adjastable, the link being cranked to pass through a slot. in the lever and having a spring catch 42 co-operating with notches 39<1> in the lever. The three camoperated levers are actuated by cams rotating with a worm wheel 13, Fig. 1, driven by a worm on' a shaft 4 normally clutched to a driven pulley. At every revolution of the cam shaft, or at half a revolution, a pin 119, Fig. 9, carried by the cam shaft engages a step on a link 116 pivoted to a clutch-withdrawal member 113. When it is desired to restart the machine, a treadle 120 is depressed, a link 124 then actuating a bell-crank lever 125 supporting the link 116 to lift this out of the path of the pin 119. The rotary 'beater has the usual series of peripheral bolts 11<11>, Fig. 5, carrying loose beating rings which increase in diameter from the sides to the centre, so that the beater has a convex contour. The beater is mounted on a shaft 7, Fig. 1, driven by belts 9, 10 and mounted in a casing 3 adjustable towards and from the shoe support by a hand-wheel 79. A side beater 66, concave in vertical contour and convex in horizontal contour, is reciprocated by a triangular cam 69 driven by a chain from the shaft 7, the cam shaft being supported by arms pivoted on the shaft 7. The side beater is pressed toward the work by a spring 74 adjustable by a hand-wheel 78, and is backed by a weight 80 adjustable about the cam shaft by a handle 81.
