SU24998A1 - Watchdog watch for night watchmen - Google Patents

Description

The main patent No. 3480 describes control hours, which are intended both to monitor the vigilance of night watchmen and to control the actual attendance of places indicated by them in the guard. In these hours, installed in the office of the controlling person and receiving current from the inductor, which is operated by the watchman and is actuated by him after connecting the inductor plug to the plug installed at the controlled posts, a polarized relay is connected and connected to the lever and serves induction of the relay by the inductor current from the control posts to communicate the reciprocating motion to the dogs, in order to bring the ratchet sitting on the axis equipped with a screw into rotation; the worm is articulated with the shoulder sliding over the contacts and with the gear wheel, which serves to periodically press the short arm of the lever, the long arm of which carries the needle, which serves for marking marks on paper placed on the disk, which is rotated by a clock mechanism. In the dependent author's certificate, the proposed device is designed to use direct current, for which purpose the relay bark is provided with a spring-loaded contact plate, intended for alternately switching on both cores and located between the relay and the contacts. For the purpose of signaling from individual points, a switching device was used, consisting of switching plates and one plate isolated from the last one, communicating with the signal circuit with a screw, and screwed onto the insulation of the contact plate.

In FIG. 1 depicts a communication circuit; FIG. -2 and 3 - type of switch, in two projects; FIG. 4-view connection of a polarized relay.

On the reinforcement extension 62 (Fig. 4}, the relays 29 are fixed to the insulation of racks 54 and 55, through which the contact screws 56 and 57, which are connected by screws 60 and 61 with the ends 51 and 52 of the windings of the coils 29a and 29c, are passed.

On the extension of the lever 27, the core 28 is secured with a screw 59 by a spiral spring 58, which attracts the spring plate 53, which also serves as an extension of the lever 27 for contact with the contact screw 56; At the same time, one of the halves of the core 28 is close to the core of the coil 29c.

The coil spring 58 serves simultaneously as a conductor of electric current and its second end is attached to the walls of the mechanism, through which the current from the switch from the watchman’s points passes, to be pulled. The second ends of the coils 29a and 29b are interconnected; the end of them 50 is connected directly to the clamp 5 (Figs. 1 and 3), which causes the electric current from the direct current network.

Clamp 11 is connected to an insulated plate (Figs. 2 and 3) 44 whose end is in contact with a screw head 43 securing the switch plates 45, 46 and 47 on the insulation 42 attached to the end of the axis 19 with a switch plate (shoulder) 18 and the insulating plate 48 of the insulating plate 18 from the plate 45 partially lying on it. When the axis 19 rotates, the contact plates 18, 45-47 rotate simultaneously through the contacts ej - ei, the plate 18 serves as a conductor of electric current for marking with a needle on the dial with next p nkta and plates 45, 46, 47 (for four hours lunkta) serve to supply signals -with any of the other items.

Along the line of wires (Fig. 1) from the control hours to the guard area, where a, a-, a and a, and. Are distributed with a single-wire or two-wire system, above the terminals 1-4 and contacts "1-04 the electric Ki lamps are included -Ht that may be red, and. - white; From the terminal 11, the wire 10a directly passes through the signal bell 49 and is connected to the wire 10 of the electrical network.

Thus, if the clock is included in the direct current network and the watchman presses the next button, for example, the current will close and flow through the wire 9 through the light bulb L1 and the light bulb HI, through: zazhi1 1, connected to the contact in | plate 18, axis 19,: spring coil spring 58, spring plate 59, through the contact -h:; | UKIHT 56, in rack 54, the end of the cable 51, the coil 29a, its second end 50, the clamp 5, the wire 10 of the electrical network and the contact aj. At this point, the core of the coil 29d pr no no soul mate

The core 28 and at the same time the spring plate 53 will contact the contact screw 57, and therefore the current will flow along the coil winding. 29c, m again through coil 29a and so on, drive the continuous oscillation of the measr 28 acting on the lever 27 and the pawl 26 until the plate 18 interrupts the current with contact b and connects with c. At the same time, the plates 45, 46, and 47 slide along the contacts in., Take and sg and go to place, take, and place. From the moment the plate 18 is separated from pin 61, plate-.45 is connected to the next and the glow is on the same line 9, the bulb goes to and ./Zj, and the bell also gives a signal, since current instead of coils of the relay 29 will flow through plate 45 , a screw 43, a plate 44 connected by a wire with a clip 11, a wire 10a, a bell 49 and a wire 10 in which the current of the electric network is connected. Thus, the watchman will know that the dial of the watch has a needle made a needle and he should go to the next next contact a.

With the same success, by connecting the coils 29a and 29c (Fig. 4), the relay 29 will also operate with alternating current.

From the above it can be seen that from points 1-a, along lines 6 - 9, the connections of the plates 45 - 47 with the contacts in. - in | in case of fire, for example, conditional fire signals can be given. Replacing the rotation of the axis 19 (Fig. 2) from a polarized or even ordinary relay with a variable pass through the electric current coils can be used for the same purpose as a clock mechanism, with the axis 19 for actuating the switch plates 18 with insulation 48 and and the gear 20 can be replaced by one of the gears of this mechanism; Thus, for starting and stopping the wings, which regulate the speed of rotation of the mechanism, the lever of the core of an ordinary electromagnet will serve.

The subject matter of the invention.
