CLASS 83: Clocks.

The subject of the present invention relates to a system of clocks in which a main movement T and the slave clocks SS ¹ S ² etc. regulated by it are connected to one another in such a way that an electric current is conducted from the main movement into a main line every minute The hands of the slave clock are thereby moved forward one minute (either immediately or by redeeming the movement), and that those slave clocks which have remained behind are corrected at the end of each hour (or half an hour) by rapidly successive impulses, while ' those who have gone ahead stand still until the right time.

This is mainly achieved through the following means:

. ι. By providing the main gear T with a main power switch L and a power switch GH , whereby the power is closed once every minute.

2. By a swinging current closer J on the main gear T, which at the end of each hour (or half an hour) sends rapidly successive electrical impulses through a secondary line and the secondary clocks are set in the specified manner.

3. By the main current switch L, which opens the main line shortly before the end of a period of time and closes the secondary line and switches back to the main line at the end of the period, in connection with the current breaker G H and the oscillating current breaker J of the main gear mechanism, the electromagnets and Current switches L ¹ L ' ² L ^{3 of} the slave clocks and ■ the two electrical lines, whereby the hands of the slave clocks are moved forward in the specified manner and are set correctly.

Fig. 6 shows such a connection, but the clocks go unequal, the one before, the other after,

Fig. 7 shows the connection of the main movement T with the primary clock P, and

8 shows the arrangement of the secondary clocks according to the relay system.

In Figs. 1 and 2, T denotes the main movement with the two clock plates A. B is the main spring, α the wheel located on the spring housing. This is connected to a gear wheel b through intermediate wheels,

which sits firmly on a shaft c. On the latter there is also the climbing gear C, which is provided with a number of wing arms dd 1 d ' ² and d ^{s , on which laterally projecting teeth 1,} 2, 3 and 4 are attached near the outer ends. The purpose of these teeth is to regulate the rotation of the climbing wheel through the pallets 5 and 6 of the pallet lever D. This lever is arranged to be rotatable about the pin g and its movement is limited upwards and downwards by the stops e and f. The pallets 5 and 6 of the lever D are, as can be seen, arranged in two different vertical and horizontal planes.

^{As FIG. 1} shows, the pallet lever D is pressed by the spring g 1 against the stop e , which has the effect that the upper pallet 5 engages in the teeth of the climbing wheel and prevents the same from moving. The gears are thereby. stopped. If now the pallet lever D rotates about its axis in the direction of the arrow (Fig. 1), the tooth 1 is released from the pallet 5, and the climbing wheel can rotate in the direction of the arrow indicated on it.

Since the pallet lever now rests against the stop /, the pallet 6 located on the lever is in the correct position to stump against the lower edge of tooth 1; the jamming wheel only turns a very small amount. Since the pallet lever now returns to its normal position against the stop e , the pallet 6 triggers the tooth 1 and the ratchet wheel completes a quarter turn, whereupon its movement is inhibited by striking its tooth 2 against pallet 5.

The proportions of the clockworks are such that for every quarter turn of the clock Steigrades the wheels to move a distance on the dial which takes a minute is equivalent to.

The main gear mechanism can be triggered in various ways, e.g. B. by connection to a main or primary clock P by means of a rod F which depresses the pallet lever D once a minute, as shown in FIG. The lever D is operated by a thumb or an eccentric h on the steering wheel shaft. The lower end of the rod F rests in a sleeve on the pallet lever D which is designed as an adjusting screw j (FIG. 1) and which screw is secured in its position by the nut i.

The - current closer of the main gear mechanism consists of a contact roller G and a contact spring H. The roller G is connected to the shaft c of the climbing gear by the gears k and b; the gears mentioned are set up in such a way that the current is closed once for every quarter turn of the climbing wheel, ie once every minute.

On the shaft E of the minute hand m , a disk / is fixed immovably, which is provided with two pins 7 and 8. The same are attached on the opposite sides. The pin 7 is set up in such a way that when the disk is turned around it acts on the end of a swinging lever which is rotatably attached to the bearing plate at η. This lever /, which is to be called the current closer, can swing freely about its axis of rotation, and if the pin 7 does not attack it, it hangs in a vertical position. The contact bead 0 is located on the hub of the lever /. A spring K, which is fastened to a support ρ and isolated from the bearing plate, slides on the hub. With each rotation of the disc / in the direction of the arrow (Fig. 1), the pin 7 engages the .Stromschliefser J and rotates it around its pin until it reaches the position shown in Fig. 3, whereupon the other Rotation of the disc / the current closer / is triggered. The drive transmitted to the normally opener / drive causes repeated oscillations of the same, and with each oscillation the contact 0 comes into contact with the spring K , whereby the current is closed.

The pin 8 is arranged on the disk / in such a way that it engages one arm of a lever or main current switch L which is rotatably attached to the bearing plate A at q ■. At its lower end it is provided with a contact spring r, which plays 5 s ^{1 between two contacts isolated from the bearing plate.} A spring t presses against the main current switch L and puts r into a conductive connection with s. However, when the pin 8 engages in the lever L , the same is rotated a little about its axis q and contact r is connected to contact r ¹ . As the disc continues to rotate, the pin 8 slides on the nose of the lever L , and the latter returns to its initial position, ie contact between r and s is restored.

The contact r of the main power switch L comes into conductive connection with the contact s ¹ some time before the end of the hour, and the arrangement is expediently made so that the contact mentioned at least five minutes before the end of the hour is explained in more detail below Reason occurs.

The secondary clock S (Fig. 4) coincides with the main movement as far as the gear train and the escapement device come into question, with the exception that the pallet lever D is provided with an armature m ¹ , which is operated by an electromagnet. M is attracted when it is energized.

A thumb disk P is firmly connected to the shaft of the minute hand m , which moves a changeover switch L ¹ , which is rotatably arranged at q ^l on the bearing plate, and at the lower end of which there is a contact spring r ¹ , which insulates between two of the bearing plate Contacts s ² s ³ plays. A spring i ¹ , which presses against the switch L ¹ , prefst the same against the thumb disk I ¹ . While the upper end of the switch L ^{1 is} in contact with the thumb of the disk J ¹ , the contact between spring r ¹ and pin s ^{3 is} established; If, however, the changeover switch mentioned has slipped on the thumb of the disk I ¹ , contact between spring r ¹ and pin s' ^{2 is} established.

It is now evident that, since approximately one half of the disk / 'has a larger and the other half a somewhat smaller diameter, the spring r ^{1 is} in contact with pin s ³ for half an hour and in contact with it for the same time Pen s' ² .

It now remains to describe the arrangement of the circuits.

Fig. 5 shows the arrangement. of clocks, connected to one system.

T is the main movement with the closing switch G H. SS ¹ and S ' ² are the various secondary clocks, B * the battery or other source of electricity and MM ¹ and Af ² the relevant electromagnets on the secondary clocks. These electromagnets can be “wrapped twice, that is, both with the main line and the secondary line, or, as shown in the drawing, in such a way that the main line is wrapped around one leg of the electromagnet, while the other leg is wrapped in the same way by the secondary line is wrapped.

The arrangement of the main line to connect the main gear or the primary clock with the slave clocks is as follows:

One pole of the battery B * is connected by wire ίο to the contact (bead) ο of the contactor J ; from there a wire ii leads to the contact roller G of the current breaker GH; from H a wire 13 leads to contact r of the main circuit breaker L, and contact 5 is connected by wire 12 to the coil ra ^{2 of} the electromagnets MM ¹ M ' ² . 12 * is the return line to the opposite pole of the battery.

The circuit of the secondary line is as follows:

Contact s ^{l of} the main power switch L is connected by a wire 14 to contact r ^{1 of} the switching lever L 'of the secondary clock 5. Wire 15 connects contact K with wire 14. Wire 16 connects contacts s of changeover switch L ¹ with one end of the winding of coil wfi of electromagnet M. Wire 17 connects the opposite end of the coil winding with contact r ² of changeover switch L ² at clock S ¹ ; Contact s ^s of said switch is connected to one end of the winding of coil m ³ of electromagnet M ¹ by wire 18; the opposite end of said coil winding is connected by wire 19 to contact r ^{3 of} the changeover switch L ^B at clock S ² . Contact s ^{1 of} the clock S ' ² is similar through wire 20 with the winding of the coil m? the clock S ² connected. From the opposite end of the coil winding, the current is conducted through wire 21 to the return line 12 *.

The contacts s ² s ⁴ and s ¹⁵ are with wires \ η. _; ίο, and 21 connected by wires 22, 23 and 24. Appropriate resistors JR R ¹ and JR ² are connected in the wires 22, 23 and 24 in order to keep the resistance ratios in the line at the same level if one of the clocks is switched off.

During the greater part of the hour the main current switch L has to close the circuit at Contact s .

The clocks are driven by a current sent into the main line as follows:

As already mentioned above, the current breaker G H closes the current every minute, which comes from the battery via the wires 1 o and 11, current breaker G H, wire 13, contact r of the main current switch, coils ni ^{2 of} the electromagnets MM ¹ and M ² , wire 12 * goes back to the battery. By energizing the electromagnets mentioned, the pallet lever is moved in the secondary clocks and the hands of the clocks are all moved forward by one minute.

If, however, the pointers of the primary clock or the main movement are five minutes before the hour is up, the pin 8 engages the main power switch and turns the lever L into the position shown in FIG. 5; here ■ the circuit in the secondary line is closed, and current flows from one pole of the battery B * via wires 10 and 11, current closer G H, wire 13, contact r, pin ί ¹ , wire 14, contact r \ ~ Pin s ³ , wire 16, coil m ³ of electromagnet M, wire 17, contact r ² , pin s ⁵ , wire 18, coil Ot ³ of electromagnet M \ wire 19, contact r ³ , pin ⁷ , wire 20 ,. Coil m ^{B of} the electromagnet M ² , wire 21 and through the return line 12 * to the opposite pole of the battery, thereby triggering the gear train of the secondary clock once every minute as before.

When the hour has elapsed, the normally open contact J vibrates, as a result of which electrical currents are repeatedly sent into the secondary line. Since the clocks in Fig. 5 are all drawn in the correct position, the switch L ¹ L ² and L ³ at the end of the hour, since the same lever on the thumb of the discs

J ¹ I ' ² and / ³ slide off at the same time, the contacts between r ¹ r ² and r ³ , s ² s * and s ^{6 are} established; hence the currents mentioned above; which go out from the current contact J , ineffective, since they only the resistors R JR. ¹ and JR ² flow through.

In Fig. 6, the clock S is shown as correct. Clock S ¹ slows down and clock S ² goes about 6 minutes ahead. The time on the main aisle is indicated up to 1 minute before the hour is up. The current will now go through the circuit as follows: The current flows from battery JB * through wires io and ii, contacts GH, wire 13, contacts r and s \ wire 14, contacts r ¹ and s ^s , wire 16 and coil m ^{3 of} the electromagnet M, whereby the hand of the clock is brought to the full hour. This is associated with turning the switch L ¹ as a result of sliding

J ¹ , where-

is brought into conductive connection by contact r ¹ with contact s ^2; from the coil m ³ the current goes through wire 17, contacte r ² s ⁵ , wire 18, coil m ^{3 of} the electromagnet M ¹ to advance the hands of the clock S ¹ by one minute; The current goes from coil Mi ³ of electromagnet M ¹ via wire ig, contacte r ³ s ^e , resistor JR ² , wires 24 and 21 to return line 12 * and to the battery.

The clock S ' ² is therefore switched off from the circuit for another minute. At the full hour, after the pin 7 has slipped on the lever, the contactor J comes into operation and the circuit is now closed as follows: From battery B * via wire ιό / Contact 0 K, wires ι 5 and 24, Resistor JR, wire 22, wire 17, contacte r ² s ⁵ , wire 18, coil ^{ms of} the electromagnet M ¹ , whereby the hands of the clock S ¹ advance one minute and are set to the correct time, whereupon the changeover switch V ² at s ^s interrupts the contact and establishes the same ^{at s 4.} From the coil Ot ^{3 of} the electromagnet Ai ¹ , the current goes back to the battery via wire 19, contacts r ³ and s ^e , resistor JR ² , wires 24, 21 and 12 *. The next current sent by the Sfromschliefser J has no effect on all clocks. It should be noted däfs AM S ^'2 besides for five minutes activity has remained and still going on a minute. During the next period it is switched off from the secondary line for an impulse and then comes into operation again. It is clear that the circuit through the branch line could be completed ten or more minutes before the end of the hour; however, five minutes are sufficient for practice.

Instead of the lever on circuit breaker J , a spring can also be used to close the circuit repeatedly. If the lever J makes three to five oscillations with each release, an error of three to five minutes at the end of each regulation period (hour) can be corrected.
