Abstract: 371,090. Delivering measured quantities of liquids. SOC. D'ETUDE DE DISTRIBUTURES AUTOMATIQUES, S.E.D.A., 22, Rue d'Athenes, Paris. Feb. 16, 1931, No. 4895. Convention date, Feb. 14, 1930. Addition to 353,605. [Class 106 (v).] In the petrol distributer according to the parent Specification the changeover slide valve 2 moved by the pressure of the liquid is adapted to be locked to a piston 7 of larger diameter, the piston and valve moving together as a differential piston to move the valve to the position for discharging the measuring chamber 3 and the valve 2 being moved alone to the position shown for charging. The locking device is liberated upon descent of a float 31 in the discharge chamber 11. The rod 6 of the piston valve 2 passes through the piston 7 and is adapted to be locked to it by a key 25 taking in a groove 26 in the rod, the key being slidably and rotatably mounted on a fixed pin 27 and also rotatable within a ring 28 rigid with the hollow rod 10 of the piston 7 and operated by a notched finger 35 controlled through lever 33 and spring 37 by the float 31. A spring tends to keep the key 25 in the groove 26 and it is lifted out of the groove when the float falls. The valve 2 thus freed from the piston 7 is moved by the liquid pressure to the charging position shown, the piston 7 following under the action of a spring 13 and bell-crank lever 12 acting on the outer end of the hollow rod 10. The key 25 carried along its axis 27 by the piston 7 thus moves off the notch 38 of the finger 35 and when the piston reaches the position shown the key springs over the coned end of the rod 6 into the groove 26. Petrol enters the measuring chamber from an inlet 4 and when the measuring chamber is filled the rise of pressure acting differentially on the piston 7 and valve 2 moves the valve to the discharge position and the petrol is discharged through a pipe 5 into the chamber 11. As the float rises the finger 35 is lowered and the notch 38 re-engages the key 25 by the action of the spring 37. Fall of the float as the chamber 11 empties again frees the piston valve 2 and the operation is repeated. A rod 14 on the valve 2 actuates the counter through a lever 16. Leakages between the rod 6 and piston 7 are collected in a channel 21, flow intq a chamber 20 and are discharged through a pipe 23 to the reservoir. To prevent the valve being locked in an intermediate position a chamber 24 is provided in which air is compressed during filling of the measuring chamber. 371,122. Coin-freed apparatus for vending hot sausages &c. MODRZE, H. J., 1, Siehenhufenerstrasse, HOFMANN, W., and HOFMANN, F., 63, Frankfurterstrasse, both in Breslau, Germany. March 12, 1931, No. 7666. [Class 27.] A coin-freed vending machine for boiled sausages and similar goods, which must be heated before delivery, comprises a magazine 1, Figs. 1 and 3, in which cartridges 8 containing sausages are placed, the magazine being provided with an electric heater, if the machine is to be placed out-of-doors. Each sausage, with some of the water in which it is boiled, is placed in a cartridge 8, Fig. 10, the end of which is sealed by a capsule 301 secured by a spring clip 402. The capsule may be made of the material known by the Registered Trade Mark Cellophane. Other caps such as bottle closures or covers of readily fusible solder may be used. After the insertion of a coin to close the circuit of a motor, or to free a manuallyoperated lever, a shaft 60, driving through bevel gearing 317, 318 a cross-shaft 312, is rotated, the shafts 60, 312 bearing cams from which the various movements of the machine are derived. At each actuation a cartridge 8 is delivered from the magazine to a conduit 16 in which it rests with the cap 301 downwards and the other end engaging a stop 304, carried by a hinged flap 28 closing the conduit. A tubular cutter 300, having a blunt portion on its edge, pierces the cap so that the severed portion still adheres and the water in the cartridge runs into a tank 305, Fig. 4, provided with a run-off tube 328. The sausage, which is provided at each end with a metal contact cap, slides through the cutter and rests on the. bottom of the tank which slides on a guide 322. When the tank is withdrawn, the sausage slides into an electric heater 330 of square section having its lower downwardly inclined side closed by a movable flap 340. The sausage is gripped at its ends between electrodes 329, 331, the electrode 331 being movable against the action of a spring 333 and the electrode 329 being on the bottom of the tank 305 which has been returned to its initial position. Current is passed through the sausage to heat it for a period determined by a time-switch, after which the flap 340 is opened and the heated sausage falls on to a cardboard strip 109 fed by rollers 112, 113 from a roll. The strip is pushed through an opening 120 on to a delivery table 121 and the tray carrying the sausage is severed by a knife 115. A portion of mustard is delivered to the severed tray through a pipe 154 and check valve 153 by an extruder 149, Fig. 3. The hinged flap 28 is opened by a cam on the shaft 60 acting through a linkage 77, 32, 34 and the empty cartridge falls to a container. Cams 313, 323, 334, 341 on the shaft 312 actuate respectively mechanism for operating the cutter 300, the tank 305, the electrode 331 and the flap 340. A cam 74 on the shaft 60 actuates a vertical sliding rod 75 which causes delivery from the magazine 1 and rocks a toothed sector 118, Fig. 1. The sector 118 rocks on a shaft 128 and drives intermittently a bevel wheel 117 which through a one-way clutch 122 drives the strip feeding rolls 112, 113. An arm 407 on the shaft 128 through links 459, 457 actuates a pawl 458 which drives a ratchet 456 to rotate a nut and advance a screwed stem 150 carrying the plunger of the mustard extruder 149. Intermittent gearing 130, 132 actuates the knife 115. The bevel wheel 117 is provided with three half-teeth 251, 252, 253, Fig. 17, and the sector 118 with a plain ridge 254 to engage the plain portion of the wheel 117 thus giving a dwell, when the knife 115 is acting. The gearing 130, 132 comprises a pinion 132 having four teeth the middle two 156, 157, Fig. 15, being of half thickness. The pinion 130 is provided with three teeth and a flange 160 of half the thickness of the pinion, this flange engaging the gap left by cutting away half of the teeth 156, 157, and stopping the pinion 132, which is thus driven intermittently by the teeth of the pinion 130. Delivery of articles stored in bulk.-The magazine 1 is rocked about a shaft 175 by the rod 75 which is connected to the magazine by a pintle 406, Fig. 1. It has a discharge opening 401 normally closed by a fixed stop 4. When the magazine is swung to the left, the bottom cartridge 8 pushes the one previously delivered 8<1> into a passage 10 beneath pivoted spring- controlled guide blades 13, 14. The passage 10 leads to the conduit 16 and its bottom is inclined for the cartridge to fall down capsule foremost. When the magazine returns to its initial position, the bottom cartridge 8 travels over the blades 13, 14 and drops to the position 8<1> to be pushed down at the next actuation of the machine. The next cartridge now takes the place of the bottom one and rests on the stop 4.
