Abstract

625,213. Extruding foodstuffs &c. BUTLER, W. H:, and ROBERTS, T. May 13, 1947, No. 12860. [Class 87 (ii)] [Also in Groups XVII and XXII] An extrusion cylinder 7 is pivotally mounted near its nozzle end by means of integral trunnions 6 which engage in recesses 4 in the side plates 1 of the machine frame. When the extrusion plunger 11 is withdrawn it engages a hook 25 on one end of a pivoted lever 21, causing the other end 31 of the lever to rock the cylinder about its pivots, thus allowing the material which is to be extruded, e.g. foodstuffs or sand for foundry cores, to be introduced into the cylinder through its open end. The part 26 of the lever 21 acts-as a counterweight to normally hold the hook 25 down on the inside of the cylinder and thus keep it in place during extrusion. The hook may have a rubber pad 27. In a modification, (Fig. 6, not shown) the hook engages in a notch provided on the outside of the cylinder, and the arm 26 has a roller on the part 31 which engages the cylinder, while it is being rocked. The recesses 4 have overhanging parts 33 to prevent the cylinder rising during extrusion. The cylinder has ribs 8, running from the trunnions 6, which rest on ledges on the side plates 1. The plunger may be operated by a rack and pinion driven through gearing 17 by movement of a handle, or it may be operated by power. A guard may be provided for the gearing. The cylinder may be made of rustless iron or steel, or its internal surfaces may be vitreous enamelled or electro-plated and the face of the plunger may be electro-tinned.
