Abstract: 13,099. Lee, W., and McMurray, W. June 27. Measured quantities, delivering.-Relates to apparatus for automatically producing aÙrated liquids and delivering them in measured quantities, the delivery mechanism being controlled by coin-freed mechanism if desired. Water is drawn from a cistern 5, which may contain filtering-material, and is preferably surrounded by a casing 6 containing ice or other refrigerating-material, by a pump 2 operated by water from a pipe 1 connected with a pressure main. The water is forced up a pipe 8 containing a check valve, having a pressure regulator 10, and opening into a rose 12 into which the nozzle 41 of a pipe 37, leading from a carbonicacid container 38, also opens. The gas container has a regulating-valve 39 and a pressure gauge 40, and the perforated plate of the rose is made sufficiently thick to cause the water, sprayed into the cylinder 11, to become properly impregnated with gas. The cylinder has a glass gauge 42, a safetyvalve 43, and a pressure gauge 44. The gas valve 36 and water valve 34 are operated by levers 35, 33 connected to the rod 31 of a piston working in a cylinder 27 the passage of water to and from which is controlled by a four-way valve 23. The operating-lever 22 of this valve is connected by a rod 21 to a flat U-tube 14, connected to the lower end of the cylinder and to a ball 13, communicating through flexible tubing 16 and a stop valve 17 with the upper end of the cylinder. When full of water the ball 13 falls, and when empty it rises. The ball and U-tube may be replaced by a float in a vessel communicating at the top and bottom with the gas and water spaces respectively of the cylinder. The aerated water is forced through a pipe 46 and a normally open spring-closed valve 48 into a measuring-chamber 49 closed at the bottom by a spring-closed valve 52. When a pivoted handle 50, connected to a rod 51, is depressed, it allows the valve 48 to close and causes a pivoted rod 53 to open the valve 52 so that the measured quantity of liquid is ejected into a vessel 80. At the same time a measured quantity of syrup is discharged from a measuring-cup 57 at the bottom of a vessel 55. The measuring-cup contains a double valve 58 having a hollow spindle 59 jointed to a lever 61, connected to the rod 51 and normally depressed by a spring in a slotted casing 63. A latch piece 64 loosely jointed to the free end of the lever 60, connected to the rod 59, has a projection normally held by a spring in engagement with a bridge piece 65 so as to hold down the rod 59 against the action of a spring 66.- The glass or cup 80 is washed by water from a nozzle 72 on a pipe 71, the spring-closed valve 70 of which is opened by depressing a spring-supported lever 69 carrying the frame 68. The lever 69 and a lever 81, connected to the rod 51, may be normally locked by engagement with recesses in a weighted bellcrank lever 74, and freed when a coin enters a receptacle 76. When the handle 50 is depressed, the lever 81 acts on an incline on the lever 74 so as to tilt it until the coin falls past a projection under the coin shoot.
