Description

By rotating the axis of the table axis, a quadrangular frame with an endless screw carrying a slide with a stand1 for a pipe in which the nodal yarns that serve to select the corresponding mask are pulled, means to accelerate the production of dialing with a pin on the tablet of the viewing point, observing a little scale and sufficient accuracy.

FIG. 1 shows a top view of the device; FIG. 2 is a cross-section along the axis of the endless screw; FIG. 3-partial section of the side view of the device with a device for moving the needle tapered; FIG. 4-view of the device with the device srrhu.

In the device, the table a (Fig. 2) is fixed motionless by means of the axis b in the frame d, which in turn is fastened with a screw to the tripod. On the cylindrical tubular rod of the bed, there is a quadrangular frame r rotating by means of a clutch in horizontal direction. On the upper part of the frame, an infinite screw a / c is inserted, carrying a slider e, through which two rods S to S abutted to pass. frame walls and case. to maintain perpendicular motion of the slide e relative to the axis of the pipe, which passes over the slider under the straight to the two rods m 8 S. § and the screw g. E bottom slider e

Attach a wooden needle that lifts from the top of the table and, by means of a spring, press it on the paper when pressed. Three vertical threads and one horizontal one are drawn in the pipe, with the first threads being from the middle one at such a distance so that the angle between each extreme and middle one will be of such a size that would correspond to the required scale. In addition to the device described above, it is possible to use an additional device designed to inform the pinching needle to move in the direction of the line of sight. For this, between the posts for the pipe, below it in the same vertical plane and parallel with the horizontal axis of rotation, two holes are made, one under the other, into which two movable rectangular frames ABCD (Fig. 3 and 4) are threaded with a rod, moving from right to left and back and rotating in a vertical plane. The frames are hinged to each other through two strips, the upper frame in the middle being connected to the pipe, and as a result of this connection of the frames and the pipe, with the full position of the last frame, the parallel pipe and itself will be located. In addition, each frame is diagonal rods, articulated with a holder of a forging mechanism consisting of a slider d

(Fig. 3), the strip J moving in the slot (Fig. 4), which by one condom is connected by means of a hinge and a coupling with the rod c and the rod rotating in a perpendicular plane relative to the axis. At the top and bottom of the slider, in special sockets, is located on a ball with round holes in the middle, through which the diagonal rods pass; in addition, a knitting needle is attached to the bottom of the slider, moving up and down. When the pipe rotates in the vertical plane, the frames will rotate in the same plane, as the pipe moves to the right and left, the frames also move, and the diagonal rods, passing through the ygars in the slider, move it back or forward and back, as the guide bar EF is always in the middle and has no lateral movement. Under "tolik and (fig. 3) are adapted. two rolls), on which the paper rolls, passing under the table through it. The instrument must be attached with a milestone with a ball at the top, whose meter is equal to half the long leg of a right-angled triangle in the frame or half the length of the frame itself. In order to build a constant angle in the eyepiece, necessary for the scale, the grid should be of two parts: the bottom and the top with one vertical thread in each part. One part is set by the thread along the axis of the pipe, and the other side, to form

appropriate angle; the horizontal thread will be the glass joining line.

. To work with the device without an additional device, it is installed approximately in the middle of the section to be removed, whereby the table is brought into a horizontal position. Working with the vessel sets it consistently on all the turns, and the tenant, having previously adjusted the device, directs the pipe with an average thread to the line that goes between two different colors along the pole, then moves the slider with the pipe by means of a screw. It will not cover the same line as the middle line, only then it will be printed, marking the corresponding point on the paper, curved on the table. After the milestone, the milestone is transferred to the next point and the pipe is again directed to the milestone and the same thing is repeated as with the nerve point. When working with a milestone bypasses the whole lot, then the tenant, noting on the plan and connecting all the points in succession with straight lines, draws a polygon like the area being shot at a given scale, at an angle of 90 relative to nature.

In order to work with an instrument with a device that does not move the needle, it is placed in a horizontal position, and the tube is placed in the center of the tablet over its center and the tube is directed to the edge of the ball with a middle thread, while the side can pass through the other edge of the ball or through the ball, or to the side In the first case, without moving the tube, the point of sight is marked with a pin-needle on the tablet; in the second case, the pipe is moved to the right until the side thread covers the second edge of the ball, after which a point is marked, and in the third the pipe moves to the left until the side thread covers the second edge of the ball, then a point is planned. /

Betrays the patent.

1. An instrument for a mazulnaya shooting using a pin on the tablet at the point of sight, characterized by the use of a rotary on the axis b (Fig. 2) of the table and the quadrilateral frame scales with an endless screw ac (Fig. 1) carrying the slider e with a stand for pipe s movable yarns, and to preserve: perpendicular to the movement of the slider relative to the pipe axis, the guide rods S, 8 are designed, passing through the holes in the outer wall and resting against the walls of the frame.

2. When described in paragraph 1 of the device, noting vising. on a beam perpendicular to the line of sight, the use of an additional tool designed to tell the pin needle to move in the direction of the line of sight, using two two-way straight ABCD frames, threaded into the holes in the pipe racks below its horizontal axis of rotation and shifted diagonal rods, articulated with the holder of the impaler, walking in the slot of the EF rail (Fig. 3).
