SU16880A1 - Distance measuring device in drawing - Google Patents

Description

In the proposed device, the use of two identical diameters of the gears, mounted on a tripod rigidly bonded to the rail, equipped with a scale with divisions, coupled to the rack and having sleeves for two leashes articulated with the sliders, measures the drawing on the distance drawing to an arbitrarily varying scale moving the latter along the rail as a result of the rotation of the upper teeth on its axis and the movement of the lower teeth fixed in the slider along the tripod groove.

The attached drawing shows the front view of the device.

The device stand, reinforced at a right angle with the rail A, has two teeth D D (connected with it) of equal diameter, of which the gear D is freely seated on the fixed axis, ъ. The gear D is freely seated on the axis in the slider D moving in the groove / tripod, where the teeth are connected to each other by the propeller G. The leads I and L, articulated with the sliders and B, are inserted with the other ends into the slide holders on the gear / and the disc D sitting on the same axis with 7. When shifted to the left to failure in the engines of their edges converge (Pointer) with the rack L, which would correspond to the zero position of the scale.

and the drivers VI tf become parallel to each other and at a right angle to the crook. The tripod is equipped with a scale equal to the length of the vertical distance from the fixed axis of the gear to the center of the hinges of the sliders with divisions showing the ratios of the corresponding segments of the scale to the whole wild, the slider is equipped with the corresponding index K.

During operation, the heads of the sliders are set to the zero position, the disk is fastened ./7 with the gear D, the slider E is moved along slot A until the indicator / C comes up against the desired scale division (the gear D rolls freely along the rail) fix the slider in this position and connect the disk L with the serrated tooth D. When the B engine moves to the distance, measured by its point to the point of the stationary one, the B engine all the time shows the corresponding size according to the scale set by the slider, since the leads And and And are all the time parallel.

 The subject of the patent.

A device for measuring the distances in a drawing according to an arbitrarily varying scale, characterized in that its stand 5, provided with a scale, carries two, of the same diameter, teeth L

- and D, rotatable on the axis, of which the axis of the toothed axle D is ukreilen in the slide E, movable in the groove G of the tripod, and, apart from the serrated teeth DG, carries the disk L with holders for the leash And, articulated by the slider B, while the gear L 41meg for the leash I, articulated with the engine B, with which the teeth L and L are linked with the rack K, and both the engine and B are equipped with points and put on rigidly fastened with the support B of the rail A so that when the edges of both engines and with a fixed tip C reiki And both leash And h And become perpendicular to the p Eike A.
