The invention relates to alarm clocks with calibration distant signal formed by single strikes and relates to a design in which the distant signal passes through an escapement that only acts on the Hammerwele in one direction and is independent of the Zeitwerk with freewheel 'is effected. In a known construction with the hammer shaft, for example, there is an air piston connected, the movement of which is delayed in the associated air cylinder during the compression stroke becomes, while it runs substantially free in suction direction. A friction fit with the Werkfederwele connected controller gradually removes the air cylinder from the piston, creating the compression chamber is increased and, accordingly, the amount of delay is significantly reduced. In contrast The invention is characterized in that on the hammer shaft a thrust member for the Drive of an associated wheel escapement is assigned, in particular a segment of a circle for Drive of an escapement shaft, and that the escapement is a fidget anchor as a time-determining organ or has a mass disk.

The arrangement of the wheel escapement means that in the known delay devices necessary time-consuming and expensive adjustment work, which is for a pronounced mass production are not sustainable, avoided. The invention provides the further advantage that existing Components can largely be used to accommodate the wheel escapement.

Several embodiments of the invention are explained with reference to the drawings; it show, in each case omitting the generally known components commonly used in alarm clocks:

characterized by a toothed rake 1, which is attached to a lever 2 of the Weökankerwelle 3 is hinged. The rake 1 engages in a drive 4, which is firmly connected to a Hemmriad 5. Jamming wheel 5 is in engagement with an armature 6.

Fig. 1 shows the device in the pulled-up state. A control lever 7 is with friction on the

The spring core shaft 8 is attached. A fixed stop 9 serves as a limit for the control lever 7 when pulling up. Here, the control lever 7 is counterclockwise and rotated in a clockwise direction by the spring core shaft 8 when running down. Once the Alarm clock comes into action by the Abstellarni attached to the alarm armature shaft 3 in a known manner 10 is released by the alarm tension spring, individual strikes of the hammer take place periodically Intervals by the delay mechanism.

The process is as follows: The Weckankerwelle 3 receives a clockwise drive by pressing the Wecksteigrades 11 on the output pallet 12 b of the armature 12. As a result, the toothed rake 1 is set in motion. As a result of the one-sided ratchet-like teeth, the drive 4 is not driven during this movement, but the rake articulated with spring pressure on the lever 2 can easily slide over the drive teeth. The hammer weight 13 can strike the bell 14 with momentum.

During the reverse movement, i.e. when the entrance pallet 12a is driven by the Wecksteiguad 11 receives and the armature shaft 3 is pivoted counterclockwise (this moment is shown in Fig. 1), the drive 4 is driven by the toothed rake 1 and thus also the wheel 5 set in motion. This backward movement of the

The embodiments described above are intended for an alarm clock with a bell. Rüokwandschläger can of course also be used with this device. In this case it is not necessary to attach a hammer weight 13 to the lever 2, but a further lever or a wire with hammer weight is attached to the Weokankerwelle 3, in the area of which the rear wall post comes to stand.

The above-described designs can also be designed as a three-stage alarm clock by appropriately designing the control lever 7, 105, 204 or 302 or by a special cam disk, which can also be placed on the spring core shaft 8, 106, 205 or 305 with friction.
