FRITZ GÄGGEL in GAMMERTINGEN. Escapement, serving as a springboard.

Patented in the German Empire on March 24, 1888.

The mechanism described below is intended to cause the restlessness of a second clock makes exactly six oscillations every second (three forward oscillations and three backward oscillations) in order to achieve this to get a reliable timepiece, as experience shows - that a second clock, in which makes the restlessness more than six vibrations per second when riding and driving is weakened in their movements, while if'the restlessness is less than makes six vibrations per second, which stop moving or stop completely.

The second clock is a simple movement with a dormant spring escapement and consists of the spring house G, which engages in the drive of the second wheel α. The second wheel is in engagement with the drive of the auxiliary wheel b and this again with the drive of the escapement wheel C. The escape wheel C has six teeth, of which teeth 1, 2, 3 are used to drive the. Unrest U and teeth ^ ^ ¹ ^ ² to trigger the escape wheel. A rotatable shaft is mounted between the lower plate P and the clamp B , on which there are two levers hh ^l , of which h carries an upright pin s ² , FIGS. 5 and 6. This pin s ² is so long that it the teeth % ξ ¹ { ^{2 of} the escape wheel C can grasp. Against the outer edges of the two levers are the springs f respectively. f ^l and between the two levers there are two upright pins s and s ¹ , which limit their deflection. On the wave of the unrest (Fig. 8) there are two levers e and e ^l , the former at the same height as lever h ¹ , the latter at the same height as the escape wheel c.

In contrast to other facilities, the restlessness can perform full oscillations, ie full revolutions, while otherwise, such as e.g. B. with the cylinder clocks, the unrest only made half a deal because here the small swing pin located on the periphery of the unrest is opposite to the impact pin. For this purpose, the shaft is provided with a loosely attached swing-out pin D, FIG. 8, the pin s ^{3 is} attached to the attachment to the spiral roller and the impact pin s ⁱ on the same side in the plate P. The small ring d , which sits firmly on the shaft, prevents the swing-out pin from automatically pushing upwards (in Fig. 7 the parts of the unrest just described have been omitted). During the forward oscillations of the unrest, the swing-out pin is carried along from the right side by the pin s ³ and pressed against the impact pin s *, thereby giving the unrest an increased drive for the backward movement. During the backward movement, the pin s ³ grips the swing-out pin from the left side and takes it with it until the impact pin s * prevents a further backward movement. Here, too, the impact of the swing pin for the opposite movement (forward movement) gives the balance an increased drive, but in both cases the swing pin in conjunction with the impact pin limits the oscillations of the balance.

In Figs. 1 to 4, the mechanism is in

four different positions shown. Fig. Ι shows the moment immediately before the release of the escape wheel C. The unrest swings in the direction of the arrow and presses the lever e on f ¹ , spring f ¹ presses on lever h ¹ until it reaches the stop pin s ¹ , which then the lever h has been raised so much that the tooth \ can pass freely under pin s ² in the direction of the arrow indicated on the escape wheel. Tooth 3 now falls on the lever e ^{1 of} the balance and thereby gives the same drive to a forward oscillation, as the arrow indicates (Fig. 3). How far the balance swings forward depends on the force of the escape wheel. In the meantime, the lever e has also left the spring / ^: and the levers h ¹ and h are now pushed back into their previous positions by the spring /, ie lever h ¹ leaves the pin s ¹ and lever h rests on the pin again s. the escape is freely make one complete revolution now, the pointer of the Secundenuhr further jump to a unit of time and the back-swinging agitation by means of lever e lift the spring / ^1, Fig. 4, and the resistance to overcome the same, that is, e is at the spring / ¹ Pass by and release them, which has the consequence that the spring / ¹ lies against the lever h ¹ again before the unrest receives a new drive to swing forwards from the wheel C. This wheel has now also completed its entire revolution, the tooth ^ ² has been caught by the pin s ² (Fig. 2 and 4).

Tooth ^ ² is triggered in a very similar way by the forward swinging of the unrest, as just described for tooth ^, whereupon the unrest is given a new drive ^{by the action of tooth 1 on lever e 1.} Tooth \ ^{l will} soon be caught by the pin.s ^2; if \ ² is triggered, the restlessness is given a new drive by tooth 2.

Claims (1)

Patent claim: An escapement serving as a spring mechanism, characterized by the escapement wheel C with its teeth i, 2, 3, which represents a section of the wheel, which set the unrest by means of the lever e ¹ into large and rapid forward oscillations, while the backward oscillations of the unrest trigger the movement caused by pin s ² inhibited teeth ^ ² ^ ¹ % by lever e , in such a way that the wheel c completes a full revolution within a certain period of time containing the period of oscillation of the unrest several times and the pointer of the clock makes a jump movement during this after the tooth \ is released .
