Abstract
182,480. Preuss, E. V. June 28, 1921, [Convention date]. Shaking and jigging machines; tamping-machines.-Relates to machines of the kind in which concrete &c. is consolidated within a mould supported upon a vertically-reciprocating table and is simultaneously rammed by a rammer bearing upon the material, and consists in imparting to the mould table a sudden upward movement, followed by arrest in such a manner that the mould and rammer separate from the table and from each other and return in succession thereto. As shown, a table 1 is supported by legs 2 under the influence of opposed sets of springs 7, 8 and is lifted intermittingly by a cam 12 on a fly-wheel 13 acting upon a roller 11, the table being restored by the springs. A ram 18 is suspended by a cable 25, weighted at 26 and connected to a lever 31 which is operable to lower the ram on to the material within the mould and simultaneously to throw in a clutch controlling the shaft 14 carrying the fly-wheel 13. The mould is positioned by guides 40 controlled by a handlever 41. The cam 12, which extends only over a small portion of the fly-wheel 13, is so formed as to impart to the table 1 a gradual, followed by a sudden upward movement. The Specification, as open to inspection under Sect. 91 (3) (a) comprises also a modification in which the table is supported by a central leg coupled to a lever intermittently depressed by a bowl on the fly-wheel and restored by a counterweight. This subject-matter does not appear in the Specification as accepted.
