Description

Instruments for measuring land distances are known, consisting of two rods, connected at the upper end by a hinge and held in the open position by a hook, and at the lower ends having star-shaped circles. For the purpose of counting the number of turns of the device, when working with it, it is proposed to fix the counter at the lower end of one of the rods, which is activated by sticking the pointed end of the rod into the ground, while the ends of both rods are positioned so that they are normal to the ground surface. .

In FIG. 1 depicts the front view of the proposed device; FIG. 2 view from the front of the rod with the counter; FIG. 3 is the same side view.

The device consists of two rods M (Fig. 1), fastened at the top with a hinge W. In the opened position, the rods are held by hook A, one end of which is pivotally attached to one of the rods, and the other rests on pin B (Fig. 1) of the other AI rod, At that, for accurate installation of the latter on hook A, talrep is strengthened.

The lower ends of the rods L, W terminate at the points f (Fig. 2), above which the stellate circles B, L are fixed, which prevent the tips from deeply cutting into the ground. To measure the distance, the rods are alternately stuck into the earth with pointed ends, the latter being located with their axes with respect to the axes of the rods L; I, M (Fig. 2) at an angle such that they are normal to the ground when measured.

A counter C (Fig. 3) is attached to one of the rods, equipped with an asterisk E (Fig. 2), rotated by the rod D (Fig. 2 and 3) when stuck; a spring / 7 is provided to the ground of the pointed end of the P rod, the spring / 7 is used to reverse this end, and the pawl K (Fig. 2) attached to the rod M serves to prevent the counter rotation of the counter star E, to indicate the correct operation of the device, A call is placed on the counter.

The subject matter of the invention.

1. A device for measuring land distances, consisting of two rods connected at the upper end by a hinge and held in an open position by a hook, and at the lower ends having star-mounted ski circles, characterized in that at the lower end of one of the rods L is reinforced counter C, which serves to count the number of turns of the instrument. . 2. The form of making p described in p. 1 of the device) characterized in that the end of the rod M, on which counter C is fixed, is connected to the pointed end F movably so that when the end F is stuck into the ground and when the spring P is compressed, during rotation, an asterisk connected to the counting mechanism of counter C, 3. In the device described in Sections 1 and 2, use the lower pointed ends F of the rods M located with their axes relative to the axes of these rods at an angle such that the position of the rods the ends F were at and The measurements are normal to the surface of the earth. 4. In the device described in paragraphs 1-3, use talrep on hook A for precise installation of the rods M in their open position. 5. In the characterized in p, p. 1-4 The device is used at the counter C of the call in order to indicate with a sound signal about the correct operation of the device.
