SU36987A1 - Drive mechanism for pointing devices - Google Patents

Description

For activating indicating devices with a recording drum or paper tape, or even with a registering mechanism, as well as time-setting devices with contact devices and for signaling, etc., a clock mechanism is usually used, the spring of which, besides The mechanism of time is also used to communicate the movement to the indicating devices and devices mentioned above.

The force spring of a clock can painlessly withstand only an insignificant load by actuating, in parallel with the course of the time mechanism, any pointing device, and in parallel, actuated devices very often require a variable spring force, which is harmful to the clock itself mechanism, and often to the final breakdown. All this forced to send a thought to

the creation of an appropriate mechanism, devoid of these shortcomings.

However, the replacement in the already known watch movements for the indicated purpose of a spring power source with a load, electricity, etc., did not give a positive result.

A more tangible result was given by the use of two power sources for activating the mechanism of time and for communicating movement to the pointing device.

The present invention relates to a drive mechanism with a similar dual source of power, in which to control the course of operation of both mechanisms at the same time and jointly, doubled and tine-shaped, directed in opposite directions, an anchor designed to pass ratchet wheels is mounted on the vnlka at its rotation point.

In the schematic drawing, the image of the device of such a mechanism.

The clock mechanism, which is floated by a spring, a weight, or some other source of force 9 and 10, is divided into two parts, from which the first one serves as the time mechanism with the source of force 9, and the second part is the working mechanism for bringing in the action of the index on a similar device.

The course of the mechanism of time and the working mechanism is controlled by a common regulator 1. The working mechanism may have different speeds, and the reversing mechanism 5, or the like, is activated between the power source 9 and the stop wheel. 3. With this device, it does not matter for the mechanism time, does the mechanism work to actuate one or more index or similar devices. The stroke controller 1 controls a fork with a double anchor 2 with teeth directed in opposite directions, which is reinforced at the point of rotation of the anchor fork. Anchor 2 serves to pass a ratchet wheel 3 of a time mechanism driven by a source of force 9 through a drive wheel 7 and intermediate wheels 5, one of which engages with the anchor wheel 3, the same anchor 2 also performs work on an adjacently installed working mechanism, similar to the mechanism of time. The working mechanism consists of a source of force 10 with a drive wheel 8 coupled through intermediate wheels 6 with an anchor wheel 4.

The teeth of the anchor wheel 3 are made without lifting planes, so there is no impulse on the regulating part, so the mechanism easily transfers not provided friction or excessive load on the working mechanism. Through the mechanism described, the simultaneous and joint regulation of the course of operation of both mechanisms is permitted.
