Abstract
147,368. Pehrson, A. P., and Lloyd, F. Sept. 1, 1919. Packing sand &c. into receptacles. - In the operation of filling hollow billets with sand or the like, before rolling, the billets are vibrated; for example, by means of a cam D, a table C, and a holder B for the billets A. Drv sand as free as possible from alumina is preferred for the core. The billets, after filling, may be plugged in the manner described in Specification 112,296, [Class 83 (iv), Metals, Working].
