Abstract

1,132,209. Moulding concrete or ceramic. H. AHRENS. 12 Nov., 1965, No. 48042/65. Heading B5A. A method of forming concrete or ceramic blanks such as steps, comprises pouring an excess of concrete or ceramic into a mould 6, lowering a ram 1 such that the base 9 thereof closes the mould and compressing the concrete and squeezes out the excess. When the material has set, the ram is moved horizontally from the mould on a roller-mounted carriage 3 running in upper guides 2 before being raised to the position shown in dotted lines prior to being moved once more into the moulding position. While the ram is withdrawn the mould 6 is tilted and the blank removed. The mould may be vibrated during pressing and may also contain various inserts (13), (17), (19), (21) which are adjustable to give a varying profile to the blanks, Figs. 3-9 (not shown). In a modification (Figs. 16-19) the material is poured into a mould comprising a base palette 205, spaced from a mould table (203), and a profiled front wall 214 pivotable downwardly about a pivot 215. A press-die 209 is pivoted vertically downwardly via a two-armed lever 218 and piston 219 to compress the material, a front press (211) compressing the excess concrete 204a when a lever 226 is manuallyoperated, a flange 211a on the press (211) being guided downwardly over the upper part 209b of the die 209. Side walls (207), (208) and end wall 206 of the mould are withdrawn by foot-operated linkages, the wall 206 also being vertically reciprocable to scrape the end of the moulded blank. The mould may be vibrated, the blank and palette being removed by a fork-lift truck when the press-die is pivoted to the position shown in dotted lines and the walls 204, 206 (207), (209) are pivoted downwardly. In a further modification, Figs. 20, 21 (not shown), side walls (302), (303) are adjustable horizontally to vary the width of the mould while the moulding machine itself, including a belt driven vibrator is enclosed in sheet-metal cladding (316), (317), (318).
