Description

This invention relates to a dial gauge for recording electrical pulses along a spiral line. The recording is carried out with the help of an electromagnetic writing mechanism, movably fixed on the pointer, set in rotation by a clock or other driving mechanism.

According to the invention; o, in order to obtain a record on a spiral line on a scale, the writing device by means of a thread is connected with a fixed axis in the center of rotation of the pointer. Due to this, as the pointer rotates, the axis is wound and the writing device is displaced along the pointer.

The device is shown schematically in FIG. 1 and 2 of the attached drawing, representing two projections of the device. The driving mechanism of the device consists of the mechanism of a wall clock such as a clock or a sufficiently strong spring or electric clock. On the case of the watch, instead of the dial, a board / 7 is fixed for placing replaceable paper forms (Fig. 2). At the board / 7 on the hinges there is a reinforced frame-I for fixing the indicated forms. Instead, the hour and minute hands on the axis O are fitted with a removable strap C, which rotates with the axis O.

At both ends of the strap C, they move with a low friction of the clamp X. At one of them the writing device is strengthened, and at the other the balancing weight is I. The writing device consists of a pencil or a special pen mounted on a plate spring that presses or pulls the pencil. Under the spring on the clamp, the electromagnet E is fixed, which, when the control contact is closed or open, presses the pencil against the paper or pulls it away. The ends of the coil of electromagnet E are connected by flexible conductors to the disks M. and D or to two rings isolated from each other, fixed under the bar C in its center. The disks L and D click on the contact springs K n K-, attached to lead wires. Both clamps X are connected by two threads with the rod A fixed forcibly in the bracket Kp. When the bar is rotated under the influence of an hourly weight (or spring) of the thread, winding onto rod A, the writing device and the balancing weight are pulled toward the center, resulting in describes the spiral line indicated in FIG. 1 dotted line. Each turn of the spiral is equal to the single-half turn of the minute hand and, thus, the turn corresponds to the hour of work. Depending on the closure and opening of the control contact, the pencil will draw an intermittent coil, which can determine the number and duration of the recorded electrical impulses, as well as the day time. For convenience of reference, the blanks should have an approximate spiral printed in parallel with the actual record and a radial grid for reading the minutes.

The following are examples of the application of the described device. At the workplace, for example, of any machine, a control contact (for example, a switch, a switch, a spring contact) is included in the device circuit. In this case, the device will register the start-up time of the machine, stopping it, the duration of its downtime and operation. Using the diagrams obtained, it is easy to determine the coefficient of use of the equipment. When the device is turned on in the alarm relay circuit, it will register the number, time of day and the duration of the alarms. In installations with automatic temperature control, the device, when turned on through the executive relay, will record the time and duration of switching on and off of the heater. If you make contacts at the end of the conveyor, at the point of exit of finished products from to: using the proposed device, you can record the time of vyzusk, time intervals in the receipt of products, the duration of loading, etc. In general, the device can be used wherever time is required processes.

With a slight complication, the device can be adapted for color recording of two, three and four curves simultaneously. The scale of the device can be equipped with movable

contacts installed in the right places of the scale and closed the pointer. Such contacts allow you to send signals or introduce automatic process control over time.

PRINCIPLES OF THE INVENTION.

Claims (3)

1. A circular dial recorder for recording electrical pulses using an electromagnetic writing mechanism, mounted on a rotating indicator using a clock or other moving mechanism, a rotating pointer on which the writing device is movably mounted in guides to allow its free movement, distinguished by that, to obtain on the scale of a circular recording along a spiral line, the writing device is mechanically connected, with the aid of a thread, to a fixed axis located in the center To the center of rotation of the pointer, with the intention that as a result of winding a thread on it, simultaneously with the rotation, there would be a uniform displacement of the writing device along the pointer. 2. In the device according to claim 1, use a counterweight movably mounted on the opposite shoulder of the pointer and connected with a thread to a fixed axis so that the counterweight moves simultaneously and synchronously with the movement of the electromagnetic writing mechanism. 3. Application of the device according to claims. 1 and 2 for sending signals at a predetermined period of time with the help of movable contacts, which are installed at the right place on the scale and intended to close them with a rotating pointer.
