Description

The clutch of the hand-rotated gear simultaneously with two mutually perpendicular crescenders, one of which is located on a strut movable in the cage articulated with the clutch on the arrow, while the other of the caravan moves in the slot of the rod, one end of which is hingedly articulated with the same arrow, and the other has an arc with divisions is meant to carry out a device for comparing two sizes with a direct indication along this arc with divisions of their ratio.

In FIG. 1 depicts a top view of the proposed device; FIG. 2 is a side view.

The device consists of the desired length of the longitudinal rod A of any section, terminating on one side with a hinged head, with the other an arc with a radius equal to the length of the rod, and having a longitudinal slit along the entire length, in which the propeller B. moves. the arrow B, and the holder G, with strictly perpendicular openings, freely fit on the rod and can be fixed to it with a stopper in it D. Through the second opening of the holder G, the strut E is provided, provided with a longitudinal rack having a tooth pitch equal to the step remalery B and terminating with

a hinge articulated with a clutch // mounted on arrow B. Both cruise loops are simultaneously coupled with gear wheel K mounted on holder G. Needles L, M and H are on the same line, but needle L is fortified anchorlessly on rod A at the height of the hinge arrows B, needle H is fastened to holder Y at the height of the center line of the spacer E, and finally needle M is fixed in creamer B. Free end A has an arc with divisions on which the numbers with dashes show at point a the ratio of the corresponding segments perpendicular to rod to its entire length. In the drawing, the unit of length perpendicular to the adopted length of the tangent of an angle of 45 °. When the arrow B is set to the zero position, it becomes parallel to the rod A, the hinge of the coupling I will be on the line connecting the head of the arrow with the zero division of the scale, and the needles H and M will converge to one point.

B in the larger of the sizes being compared between the needles L to N, by moving the holder G along the rod, fixing the holder with the locking screw D in this position and rotating the gear wheel K take the second size between the needles H and M. Arrow B will show how many times one size more than the other, since the extension of the strut is always equal to the distance of the needle M from the needle H and the section cut off along the perpendicular to the point a is always proportional to the advancement of the strut.

The subject of the patent.

A device for comparing two sizes with a direct indication of their relationship, characterized by the fact that the manually rotated gear K is coupled simultaneously with two mutually perpendicular kremalyeri,

one of which is located on the strut f articulated with the clutch And on the arrow B. and movable in the holder G, which has a needle (tip) I and the locking screw L, the other of the creamer B, which has the needle M, is made movable in the slot of the rod A, one the end of which, having the needle L, is articulated with the arrow, and the other end of the rod A has an arc with divisions showing the ratio R: tg equal to the ratio of the LF distance to the MF distance.
