SU110A1 - A device that automatically records the distance traveled - Google Patents

Description

The proposed device has the purpose to mark changes in the directions and length of sections of the path being traveled and automatically bring these changes to a map of the path that can be used in various cases of aviation, navigation, scientific intelligence and shooting plans, as well as in everyday life when passing without forest roads, etc. closed spaces.

FIG. 1 the device is presented assembled from above; in fig. 2 is a longitudinal section, and in FIG. 3 - cross section of the device; FIG. 4 - 8 give some details of the device device.

In the center of Box A, FIG. 1-3, the ball B is freely positioned, supported by the balls G sitting in the sockets of the rim X, reinforced in the box. Thanks to the ball hardening, the ball B can freely and easily rotate in any direction. On the lower side of the ball B is located, on the lifting pin I, the magnetic arrow D, to the stop cup E of which, on top, on the hinge O, a feeder consisting of a fork // {and roller 3, is fixed. 6 and 7; the fork and the roller are under the action of a coil spring Y compressing them. Pin And can move up and down in the frame / {, D FIG. 8, using the lever M, rotating on the axis O; one end of the lever is pivotally connected at the point Oz to the pin, while the other end of the lever M is supported by the coil spring W and point 7, Fig. 2, is connected to a pedometer or other instrument measuring the length of the space covered. When the pin is in the lowered position, the magnetic needle D sits freely on the tip of the pin and can take the direction corresponding to the poles; when lifting the pin I, the fork Zh and the roller 3, being slightly compressed by the coil spring U, are pressed into the surface of the ball and, with a further rise of the arrow, the feeder, the fork – roller, gradually moving apart, turn the ball B with the tips of the fork Zh in the plane of a hundred arrows at the time of its rise; roller 3 serves to balance the pressure on the ball. For drawing on the ball B lines of the traversed path, the ball from the surface is covered with a layer of white rubber B, and on top of the ball, on the line of the diametrical tip

the pin I, in the glass P of the box, the pencil C is strengthened; FIG. 2, 4, inserted under the pressure of the coil spring F into the sleeve t. With each hit of the counter of the pedometer or other device serving for counting the distance traveled, the rods // with the aid of the lever M, the fork billet // moves the ball B in the plane the magnetic needle, when the counter pressure is stopped, the rod // is lowered and the magnetic arrow freely takes the direction corresponding to the poles. As a result of the device operation together with the meter, a pencil will draw a continuous line on the B surface of the ball, in which the size of the straight line segments will correspond to the number of counts of the meter, and the direction of the lines will correspond to a hundred magnetic arrows during lifting.

SUBJECT OF INVENTION.

A device that automatically records the distance traveled in which the turns of the path are determined by changing the position of the magnetic needle with respect to the surface associated with the body of the device, characterized by the use of a magnetic needle D equipped with a fork 1 rotatable on the axis Oj and a rotating roller 3, periodically raising the arrow when pressing the end of the / 7 lever M pressed to the covered with rubber B ball B, laid on rollers T in frame X, and that it rotating under the pencil T, traced on the rubber surface of the ball th path.
