Title: Food mixture depositing machine
IPC: A23G3/02
Filed: 1963-04-09
Abstract: 963,099. Apparatus for filling pies &c. W. T. COWLEY. April 9,1963 [April 10, 1962], No. 14041/63. Heading A4R. [Also in Division B8] A food dispensing machine for filling pies &c. comprises a cylinder block 18 having an aperture for feeding a charge of food into the cylinder space, a sleeve 28 slidable within the cylinder from a position where its lower edge lies above the charging-aperture to a position below the aperture, a piston 37 operative within the sleeve, releasable retaining means 45 for retaining the piston in an intermediate position during downward movement of the sleeve and closure means, such as a gate 65, having a discharge opening positionable beneath the cylinder. As described, the cylinder block has a row of cylinders, each fitted with a sleeve and piston. The sleeves 28 are mounted on a carrier plate 27 secured to a pair of posts 16 which are carried by a bridge 24 and arranged to slide through bushes 15 in the frame 10 when acted upon through a cam-shaft 21. In the procedure of filling a tray 12 slid beneath the machine on rails 11 rotation of the cam-shaft results in lowering of the sleeves to enclose the volume of food charged into the cylinders from a hopper 61; the piston-retaining means 45, which are slidably mounted on the posts, also drop a certain amount during this sleeve movement, an amount which is limited by stop-screws 47 passing through clearance holes in a frame-plate 19 and depends on the desired quantity to be dispensed. The gate 65 is actuated by an air-cylinder through a pair of links 66 and, when the air-cylinder is operated by a trip 57 to uncover the discharges, the pistons are released from the retaining means so that they fall and eject the charges on to the tray. The piston-retaining means consists of a bar 45 and a latch bar 43 which, when struck by a pair of bars 54 actuated by the air-cylinder, slides beneath the bar 45 against the action of a spring 56 for releasing the latches 42. After the pistons have reached the ends of their strokes, they are carried back to their latching positions by the sleeve carrier 27 which is raised by the action of the cam-shaft 21. The reverse movement of the air-cylinder for returning the striker bars and gate is initiated by an air-valve 68 operated from the cam-shaft. For cleaning purposes, the piston assembly is lifted by means of a chain which is wound over sprocket wheels 72 by rotating a handwheel 74; the latches 42 are made detachable from the pistons by the provision of key-hole slots 32 in an intermediate plate 31 which is slidablymounted on the posts.
