Description

Automatic dispensing machines are known for dispensing a certain portion of a liquid by lowering a contacting token or coin in them, which serves to close an electromagnet circuit that actuates taps or valves. In the proposed automaton, when lowering a contacting token or coin, an electromagnet circuit closes, attracting measles in the form of a two-armed lever, one end of which is designed to transfer the ratchet and the other to drop the counter or coin from the contacts. Ratchet is arranged according to the type of shields of conventional switches with diametrically located conductors separated by insulators. The switch closes the circuit of the electric motor that opens the valve by means of a worm gear. On the axis of the worm gear sits a disk on which a contact plate is fastened, which serves to close the electromagnet circuit, in order to place the switch in the open position. The electric motor is connected through a rheostat, the slide of which is articulated with the centrifugal regulator.

On. The drawing shows the general scheme of the automaton.

(66)

The proposed machine is equipped with a locking plate 5 mounted on the transfer organ. coupling valve 9 with an electric motor 7. The designated plate is designed to remove the counter from the contacts for closing the electromagnet 15 circuit in order to reverse the switch 15 of the electric motor 7 to the open position. An electromagnet 14 is permanently connected to the circuit, which serves to keep the valve 10 in the open state, locking the tempering pipe 13 in the absence of mains voltage. The anchor 16 of the electromagnet 15 is made in the form of a two-armed lever, one end of which is designed to transfer the ratchet switch 15, and the other serves to drop a token or coin from the contacts.

The terminal mechanism between the motor 7 and the tempering valve 9 is the worm to 3 and the worm is 4; on the axis of the latter, a disk of insulating material is fitted, fitted with a contact (plate) 5.

A motor 1 is connected to the motor circuit 7, the slider of which is articulated with a centrifugal regulator 21, designed to rotate from the motor 7.

The scheme works from the urban lighting network. The current enters the contacts A and B and through the resistor 1 and the slider (controller 21) supplies the electric motor 7 by switching the wires through the switch 15.

The rotation of the electric motor 7 is operated by: a) a centrifugal regulator 21 (by means of a bevel gear) to regulate the supply of current to the motor, in order to avoid overloading; b) a worm k with a pinion mounted on the end of its roller, from the rotation of which the valve rod 9 operates to release water from the water standpipe.

The safety valve 10 operates from an electromagnet 14, which is permanently connected to the mains supply 51 in order to detect (due to any accident) the absence of current in the city network, the valve 10 is automatically lowered by means of the spring 11, due to the absence of current in the magnet 14, and thereby preventing the arbitrary discharge of water if the first valve 9 turns out to be lifted or stopped halfway along the way at the moment of the absence of current.

Water supply is as follows. It descends into a special (figured) hole, a contactor 18, which is a wooden cylinder, which has a wire in its body (which is indicated by a dotted line in the drawing), which has a soldering of the outgoing ends with metal tips tightly mounted on the ends of the cylinder.

At the time of the closing of the wire: part 18 turns on the current in the electromagnet 15 and simultaneously doubles its work: a) attracting the electromagnet, the rocker 16 rotates the switch 15 at one end of its circumference, turning on the current in the electric motor 7; b) with its second end, the yoke 16 simultaneously flushes the contacts 18 from the contacts into a special storage, leaving the contacts open.

Due to the rotation of the electric motor, a special disk of insulating material having a metal plate 5 radially rotated (fixedly mounted on one axle with bristles) rotates.

After one revolution, plate 5 closes the two contacts located on its path, the second circuit closes the same circuit, which was closed for the first time by the closer 18, as in this case, as can be seen from the drawing, these two pairs of contacts are included in parallel.

At the moment described above, the plate 5 automatically switches the current into the electromagnet 15 of the switch 15; the latter again has a rotation on the Vs revolution, but the second time already gives the insulation to the wires of the electric motor (in the drawing, the insulating teeth are not marked) and the device stops.

Each turn of the gear 4 of the disk with the plate 5 strictly corresponds to the flow time of a certain amount of water (bucket, barrel, etc.).

The subject matter of the invention.
