Abstract: 149,957. Smith's Sons Co., J. E. July 30, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Stream-cutting machines; extrusion machines.-A machine for serving butter, icecream and other plastic foodstuffs, comprises an insulated casing 1 adapted to accommodate a number of containers 3 for the butter &c., which containers are adapted to co-operate, in turn, with means for expelling their contents and severing predetermined portions thereof. As shown, four containers 3 are secured to a disk 9 rotatively supported upon a fixed ring 10 and operable by a central shaft furnished with a hand-hold projecting above the casing 1. The disk is locked in definite positions by the engagement with locking-recesses 15 on the disk of a bolt 14 carried by a bar 17 secured by a rod 18 which is' normally raised by a spring 20 and is depressible by a knob 19 to release the bolt. Each container is fitted with a plunger 40 adapted to be engaged by a plunger 45 operable through a lever 67 which also actuates a cutting-device. The containers are formed with projecting portions 27, Fig. 3, to engage recesses 26 in the disk 9, and are secured by locking-devices 32, and are formed with suitable discharge orifices 8. The lever 67, Fig. 1, is mounted on a shaft 68 carrying pairs of disks 71, 72 fitted with rollers 73, 74 which engage cam grooves in and rock members 78 carrying pawls 65, 66, engaging ratchet teeth 63, 64 on the rod 46 of the plunger 45. Upon depression of the lever 67, during the first part of the movement, the rod 46 is depressed to expel material through the orifice 8, and, upon further movement, a cutting-frame 128, carried by a pivoted member 126 and furnished with a wire &c. 130, is oscillated to sever the expelled material. The member 126 is operated through bell-crank levers by a rod 109 connected to a disk 110 loosely mounted on the shaft 68 and rocked by a pin 116 projecting from the neighbouring disk 71. The pin 116 projects through a slot 115, Fig. 16, in the disk 110, which is also provided with a slot 112 engaging a fixed pin 111 to limit the movement of the disk and the operating-lever 67. To regulate the amount of material severed, a second disk 113 is mounted beside the disk 110 and is adjustably connected thereto by a pin 140 passing through a hole 141 in the disk 110 and into one of a series of holes 142, 143, 144 in the disk 113; the disk 113 is furnished with a slot 114 also engaged by the pin 116. The cutting-device may be rendered inoperative by closing the slot 112 by a filling-piece 165, Fig. 19. The casing 1, Fig. 1, is furnished with ice compartments to cool the material, and is fitted with a hinged lid to provide for the introduction and withdrawal of the containers; it is also fitted with a device for extracting the plungers from empty containers, such device comprising a lever carrying a rod formed with a substantially T-shaped head adapted to engage a ring 43, Fig. 6, on the plunger. The plunger 40 is provided with packing 47 having a depending flange 48 which is secured by a plate 49; and is furnished with vents 155 which are closed by a plate 156 during the descent of the plunger, but which allow air to enter the space beneath the plunger during its withdrawal. A detent pin 106, Fig. 1, holds the rod 46 after each depression, but is released by a finger-piece 108, together with the pawls 65, 66, when the rod 46 is to be raised for the positioning of a fresh container.
