Description

Pendulum clock. The subject of the invention is a pendulum clock the pendulum according to regularly recurring periods of time, z. B. after each Minute, an impulse is given by one at the end of a swingable lever seated roll falls onto a striking disc or plate that is stuck on a pendulum and rolls off of her again. The subject matter of the invention also has a coarse control provided clockwork is provided that shortly before the expiry of a predetermined number of pendulum oscillations Z triggers the triggering organ, whereby the clockwork is stopped - is to shortly afterwards when the pendulum passes through a predetermined one Able to be restarted 'so that the specified game after expiration can repeat another period of time.

The use of bumpers that fall down and lift up again is known and so is the use of a clockwork that triggers of the push lever causes. But while the movement of the clockwork with the known Clocks from the pendulum by a Vpr acting on it, direction regulated becomes, with the present pendulum clock comes a much simpler way of correcting it to use. The clockwork can be an ordinary clockwork with devices is provided for regularly recurring shutdown and restart and for triggering a trigger lever and for Wierler returning it to his : "# initial position. I: s can choose time segments of different sizes but usually the pendulum strikes seconds and becomes (let bumps every minute granted.

The storage device turns (read clockwork at the end of every full minute starting, however, it runs a little too fast, so it's a split second stopped before the minute has elapsed; at the same time it releases the trigger the impact plate will fall (Fig. i, position I). The kick-off will be exactly on the minute granted (Fig. i, position 1I), with the lever falling further (Fig. i, position 11I) starts the clockwork again. The bump lever will eventually come back in moved back to its original position. Instead of turning the clockwork through the pendulum synchronized, one deliberately leaves it a little with the present pendulum clock run too fast, the time gain, e.g. B. within a minute, by its Stand still until (read the pendulum clears the way again after the full minute, is balanced. This is done (read the clockwork e.g. every 1 minute to the correct one Time set. It can therefore be provided with a dial which is up to indicates the correct time to a fraction of the pendulum oscillation period.

As a result of the expected small deviation of the clockwork rate the push lever hit the pendulum in different phases of its movement; by Corresponding shaping of the faceplate surface can have a detrimental effect on the pendulum gait, as is known, should be avoided.

The drawing shows, for example, two embodiments of the subject matter of the invention and a modification of some parts is shown. Fig. I shows a known device, by means of which the pendulum can be given a push; Fig. 2 shows the general Arrangement of one embodiment; Fig. 3 shows the arrangement of the abutting Part; Fig. D. shows an arrangement of the parking device that differs slightly from Figure 3; Fig. S shows the general arrangement of the second embodiment of the subject invention; Fig.6 shows the associated storage device and Fig.7 the arrangement of the abutting one Part of this embodiment. About the individual phases of the mode of operation of the subject matter of the invention To illustrate, a known type of trigger sharing is shown in Fig. i.

A striking plate --1, is attached across the pendulum - #, tan ge ß. A lever C, which can be rotated at point D, carries at its free end a roller E which, for example, falls on the striking plate every minute, shortly before the pendulum reaches its middle position or its exact minute position. In position I, the trigger has just been released. When the pendulum moves from position I to position 11, roller E simply rolls over the surface of the striking disc. In position II, the roller has reached the beveled edge of the striking plate and gives your pendulum a push when it slides off the plate. In position III, the roller is completely separated from the pendulum and has fallen down and is returned to its starting position for the next push.

In - AM . 2 is (the clockwork is marked with t, with C the push lever and with B the pendulum.

In the first embodiment (Fig. 3 ) the clockwork is a normal balance clockwork, which is provided with the additional parts shown in the figure. The full wheel I sits on the same shaft as the fourth wheel and therefore makes a quick full turn every minute; G is the unrest. The L: circular disk H is driven by a special drive mechanism and takes care of the return movement of various parts to their original position.

The wheel 1 (Fig. 3 ) is provided with a cutout T on the circumference. A resilient cover plate K that rotates with your wheel usually covers this cutout and extends somewhat beyond the circumference of the wheel. A lever L rotatable in point II is supported with its own weight by means of a horizontally protruding pin N (lein edge of the wheel I. At the end of the lever L a slightly resilient pawl 0 is articulated and underneath the balance G is arranged, on its side surfaces several laterally projecting pins P. The resilient sprinkling cone 0 supports the push lever C usually in the position shown.

The non-circular disk H is arranged so that it can operate the levers I 'and C. The mode of operation of this pendulum clock is as follows: The clockwork is set in motion finitely at a speed that an advance of one per minute is considered suitable. a fraction of a second found. The wheels turn in the direction of the arrows drawn. The cover plate K meets the pin i'4 and is pushed back by it until the cutout I comes under the pin N. This causes the lever L to drop and the pawl 0 hits one of the pins .P of the clock wheel G and stops the movement. At the same time the cone O has evaded and the push lever C falls down, so that the roller E strikes the striking plate A of the pendulum passing through the position I in FIG. Immediately afterwards the pendulum moves into position II (Fig. I), while the minute hand rests on a division of the minute division. The pendulum then receives the shock as described above. After its roller E has left the plate A, the lever C falls deeper until its arm W hits a lever S. This releases the non-circular disk which, in rapid rotation, hits the arm L%, which swings up the lever I_ again and lifts the pin N out of the cutout T and the pawl 0 out of the pins of the balance wheel. The locking cone Q resumes its previous position and the clockwork runs again. The non-circular disk H also lifts the push lever C by its action on the arm V, namely later, when the return of the lever L has taken place in its starting position, the arm R pushing the cone O back and coming to rest on it again. All parts are then back to their original position and the clockwork continues to run in order to trigger the next triggering of the triggering organ. The fraction of a second gained in the kick-off period was used up again by the shutdown process, so that the clock was set correctly by the pendulum.

Differences in the phase of the pendulum movement when the initiating organ, et-, especially as a result of the change in the speed of the clockwork and the recovery operations can be carried out in a known manner Shape of the surface of the striking plate can be rendered harmless.

The arms of the lever C are arranged so that they during the time between the release of the lever to rest the roll E on the plate A and do not come into contact with any other parts when they fall off the plate A, so that the shock generation is effected exclusively by gravity.

.By the top cap K is to prevent the pin N in the Restoring the initial position of the lever L falls back into the cutout T. The pins P are arranged in such a way that when they are released, the unrest is caused by the balance pegs gets enough momentum.

Fig. 4 shows a modified form of the locking or stopping device for the clock, whereby a quick and safe locking of the year is achieved without requiring careful adjustment of the U pin. The lever L has two pawls 0 and Z, where the direction of freedom of movement of 0 is opposite to that of Z. is. These pawls lock the pins P and Ir, so any delay is avoided is. These locking devices only act on a pin that is cheapest Place is appropriate. By placing multiple pens near the cheapest one However, irregularities in the vibration amplitude of the body will occur Balance wheel accounted for and the most favorable position of the same exploited, whereby excessive impacts on the bearings can also be avoided.

The shutdown of the clockwork could also be effected in another way and the lever L could be returned to its original position in some other way are as was shown, e.g. B. by striking the lever C on an arm of the Lever I_. The use of a restlessness as a coarse regulating element is also only an example shown by using a pendulum. Likewise, the impulse lever could triggered in a different way than shown and brought back to its original position will.

In Fig.5 the general arrangement of an embodiment is shown, in which the trigger lever is triggered electrically. t denotes that Clockwork, n a device for triggering the trigger, B the pendulum, r a Source of electricity. The electrical connections are shown in the figure and are explained below. The arrangement of the clockwork is slightly different. The oval disk H with accessories is missing and the clock can be restarted on. effected differently from the first embodiment.

In Fig. 6, the lever L, which is rotatably supported in point X, is for parking of the movement can be seen. An arm a of this lever makes contact with an arm U. when the lever L falls down and an electromagnet P releases this arm.

According to Fig. 7, a jumping cone d supports the lever C on its hook e. A rotatable contact lever f can make contact with a contact clip la by means of a beak g. On one arm of the lever C two Ouerstifte i, j are attached, which limit the play of the lever f. 'N and q denote electromagnets; the anchor of one is attached to the lever d, the anchor of the other is attached to the lift, which carries a nuerstift iii on an arid. The play of the lever Z is limited by stops: the arrangement, as far as it has just been described, is not nice and is only used here as an example.

The functioning of the pendulum clock according to Fig. 5, 6 and 7 is as follows.

The lever I. (Fig. 6) locks when it falls down (reads the auxiliary clockwork in a similar way as in the first embodiment, whereby a finite b makes contact and closes a circuit I. This circuit (Fig. 5) goes through i, 2, 3, .4. 5, yi, 6, 7, r, 1 and causes, (let the electromagnet v. Attract its armature. This causes the lever C to fall, gives your pendulum the push, thereby separating the pendulum and causing it , (let the pin i hit the lever f and close the contact io (Fig. 5) at g, h, (.Fig. 7). This closes the circuit Ti. (Fig. 5), which is connected via i, p. 8, 9, io, q, 6,;, 7-, Z. The electromagnet p (Fig. 6) attracts its armature a, thereby bringing the lever L back into its starting position and starting the clock again The connection: - c. 1> (2, 3 in.-Nbb. 5) is interrupted, thus also the circuit I Lind therefore (leg Elel; trolnagnet il. Currentless and the latch d released. On the other hand, the attracted armature brings k (Fig. 7) by means of of the pin, in the lever C back to its original position. When the lever C is moved, the pin j hits the lever f and interrupts the contact g, i.e. all contacts are now interrupted and the levers are returned to their starting position; Game at the next pulse period.

The impact plate .1 can also create the same shape as in that here Embodiment have. But (read the clockwork can be at any distance be set up by the pendulum and the device for generating pulses.
