Description

In the proposed measuring fork, - Equipped with two legs and a lever, the latter is equipped with two fingers, one of which, when measuring the Tree, acts on a correction gear that rotates a typical wheel with numbers to indicate the thickness of the tree, and the other works on the counter marking the time The measurement number is a number; moreover, in addition to a typical wheel for indicating the thickness of a tree, the plug is equipped with a standard wheel for marking its breed.

The drawing schematically depicts a view of the plug on the side.

The measuring fork consists of a ruler 15 with a threaded rod 7 located in it and two legs 10, 9, the first of which is fixed on the ruler 15 stationary, and the second is equipped with a sleeve 8 mounted on the rod 7 with a tooth / spike engaging 7. On leg 10 arm 1 is fastened with hinges, equipped with two fingers 1, 1, one of which 1 acts on counter 2 placed in iftijiKKe 10, and the other acts on arm hinged in lever 10 of the latter is in contact with the teeth of the correction gear 4 5 th wheel, seated on the rod 7 and chsnabzhonnogo circumferentially figures for

denotes the thickness of the tree measured by the fork. Next to the wheel 5 on the rod 7 there is a typical wheel 6 provided with wood designations. In the leg 10, rollers 11, 12 are installed for a paper tape, which extends between the cylindrical surfaces of the wheels 5, b and the area of the shaft 16, which is affected by a wedge 13 connected to the finger 1 of the lever 1.

When using a fork, the measurement tree is clamped along the diameter between the legs 9, 10 by moving the foot 9 along the stem 7, and the typical wheel 6 is pre-installed on the division indicating the species of the tree being measured. Moving the leg 9 causes the rod 7 to rotate together with the wheel 5,

mounted on a figure designating the thickness of the tree sandwiched between the legs. At the end of the movement of the leg 9, the tree deflects the lever 1, which

by the finger 1 acts on the counter, which marks the measurement sequence number, and with the finger I it acts on the lever 3 and the wedge 13. The lever 3, acting on the gear 4, turns it together with the wheel 4 through a certain angle at which the wheel 5 is set to an integer greater than or less than the original reading, and the wedge 13 presses the paper tape 16 to the cylindrical surfaces of the wheel 5, 6. Moving the enta by rotating one of the rollers 11, 12, imprints the readings of the wheels 5 on the tape, b using paint applied to the wheels 5 , b with roller 14, constantly finds d luminant into contact with the wheels.
