Abstract: 14,769. Ditchfield, H. July 2. Measured quantities, delivering.-In an automatic machine for supplying aÙrated liquids, and for advertising, the bottle n, Figs. 1 and 8, is supported against an india-rubber seating s in a frame p by means of a screw q. A rotatable key u, t unscrews the bottle stopper o, and allows the liquid to pass by way of the hollow frame r, v, a valve w<1>, and a pipe x to the back m of a tap c, Figs. 1 and 5, whence it passes through a perforated piece l, down a tube y, and so to a working cylinder b, in which it drives up a piston 7, loaded with a suitable weight 28. The liquid can only pass the plug valve w<1> when the frame p is vertical. When the frame p is inclined, Fig. 1, the valve w, w<1> is closed, allowing a fresh container n to be put in the frame. On inserting a coin 6, Fig. 5, a nose 4 is pushed inwards, moving a lever 3 to the left and raising a detent z from a catch on a rod h, thereby allowing a valve f, by means of a knob i, to be pushed away from its seating against which it is held normally by a spring g. This opens connection between the pipe y and the outlet e of the tap, and the weighted piston 7, descending in the cylinder b, expels the liquid. The opening of the valve f is accompanied by the closing of the passage m from the container n, owing to a solid rod k entering the passage. To prevent the detent z from being actuated by an instrument inserted in the slot, a further detent 33 is employed, against which the previously-inserted coin rests. On actuating the nose 4 by an instrument, the pivot of the lever 3 simply slides back in a slot 30 in the piece 31 without lifting the detent z. But, when a new coin is pressed upon the previously-inserted one, the wedge-shaped detent 33 is forced outwards against the action of a spring 34, and lifts a slide 32, the upper end of which forces the pivots in the slot 30 to the right, and so holds the lever 3 in position to be operated by the new coin and to free the detent z. In a modified form of tap, Fig. 9, the solid piece k, Fig. 5, is replaced by a hollow piece 24, which normally allows access from the container n to the working cylinder b, which is connected to the rear end of the tap c, by way of a pipe 27 and openings 25, 26. When the stud i is pressed in after the coin action, the holes 25, 26 no longer coincide, and communication is now made between the pipe 27 and the tap c as before. The rising of the piston-rod 8 in the working cylinder actuates a cam 11, carried on pivoted arms 10, by way of links 12. The cam engages an arm 18, and so forces in towards the centre a slide 15 on arms 16, against the action of a spring 21. A support 14, being thus carried inwards by the slide 15, releases advertisement or picture cards, displayed through an opening 20, one by one, and they fall into an empty compartment beneath. The limit upward motion of the cam 11 releases all the cards, and allows the arm 18 to catch into a slot on its edge owing to the action of the spring 21. The downward movement of the piston 8 and of the cam 11 thus rotates the drum 17, bringing the next full compartment against the opening 20, and leaving the emptied one just beneath for receiving the cards as they are released at the next operation.
