Description

In the known automatic dispensers, the inventor, in the aggregate, applied, for the purpose of continuous operation, two measuring cylinders fed from a common tank. Between the cylinders there is an axis on which bevel gears are fitted, meshed with bevel gears, mounted on vertical shafts, on which are also helical gears with uniform gaps between the teeth; the last gears engage with cylindrical gears fixed to the axis of the valves connecting the tank with the measuring cylinders and to the axis of the valves of the exhaust pipes from the cylinders. When the exhaust valves are opened, the inlets are closed and vice versa. For automatic dispensing of liquid and filling the measuring cylinders, an axis located between the cylinders is equipped at the end with a handwheel with a locking mechanism in the form of a cam ratchet with two dogs, released by the weight of a coin dog or a corresponding token falling on the tail.

In FIG. 1 depicts a top view of the machine; FIG. 2 is a side view of a cam ratchet with a coin lowered into the machine; FIG. 3 - a clutch of a cylindrical gear with uniform gaps between the teeth with gears

on axle pipe taps; FIG. 4 - front view of the machine; FIG. 5 shows a vertical section through the wall of the automaton along a slot channel that serves to eject the unsuitable coins or tokens into the automaton.

Tank 1 (fig. 1, 4) is connected with liquid by pipes 3, b with taps 4, 4 with two measuring cylinders 2, 2; between the cylinders 2, 2 passes the axis 8 with conical gears 9, 9 mounted on it, engaging with conical gears 7, 7, mounted on shafts 7, 7, on which cylindrical gears are also mounted with uniform gaps between the teeth 3); these gears engage with gears 5, 5, mounted on the axis of the cranes 4, 4. Axis 8 passes through the outer wall 35 of the machine and has a handwheel 10 outside (Fig. 1, 4), and inside the cam ratchet 28 with two dogs 12, 14 (Fig. 2), with which the dog 12 ends in a tail 13, onto which a coin lowered into the slot 31 of the machine falls; cam and notched ratchet are equipped with protrusions directed in different directions. The slot 31 when the machine is idle is covered by the edge of the protrusion 38 (Fig. 4) of the rim of the handwheel 10 and is released by the dog 14 by a slight turn of the handwheel to the right. Pipes 3, b, leaving measuring cylinders 2, 2

each is branched into two pipes 29-29, which extend outside the wall 36 of the machine, moreover, right of these pipes is equipped with an adjusting valve 17. Both measuring cylinders 2, 2 are provided with locks.

Before releasing the liquid from the automaton, one of the cylinders 2 is filled with liquid, and the other remains empty. By turning the handwheel 10 a little to the right, the slot 31 of the machine gun is released, into which a coin or a corresponding token 21 with protrusions 24 is lowered; the counter, rolling along the guide plates 16 (Fig. 2), hits the tail 13 of the pawl 12, which rises up and rests against the end of the counterweight 18. Turning the handwheel 10 to the left, the cam 27 (Fig. 2) raises the dog, lowers the counterweight, and the token is lowered into the checkout counter. The dog 12 then slides along the cam edge until it rests against the next one; its protrusion stops the handwheel. When turning the handwheel, the gear wheel with the gaps between the teeth closes the corresponding taps, as a result of which, when pouring fluid from one cylinder, the other fills. To account for the amount of fluid flowing, the outlet valve 4 is provided with a counter 30 (FIG. 1). To eliminate the incompatible coin or token being dropped, the plate 34 (FIG. 5), through which axis 8 passes, is attached to the wall 35 of the machine, except for the slot 31 is provided with a hole with an outward-opening lid equal to the width of the main slot and the length the diameter of the coin; a token lowered into the slot without protrusions 24 will fall and will be thrown out through channel 36; when using coins, all coins with a larger diameter than the length of the slot will not enter it, and a smaller diameter will fall down.

Subject patent.

1. A dispenser for dispensing liquids, characterized by cumulative use: a) for the purpose of continuous operation, two dimensional cylinders 2 fed from a common tank 1, b) axis 8 located between them with 7 conical gears in coupling with gears, designed for simultaneous control of inlet and outlet cranes 4 by turning the handwheel 10, sitting on the axis 8, by turning the locking mechanism in the form of a cam ratchet 28 sitting on the axis 8 with two dogs 12 and 14, released by the weight falling on the tail of the dog 12 coins or a corresponding token, d) cylindrical gears b with uniform gaps of teeth mounted on the axis of the gears 7, which are in engagement with gears 5 on the axes of the taps 4 and intended for periodic opening and closing of the cranes.

2. In the machine described in p. 1, use of a slot channel 36 intended to eject unmatched coins or tokens dropped into the machine.
