Description

In the proposed machine, the ruler is fixed on the caliper, connected to the nut of the lead screw by means of a turn bar, telling the caliper to move when the screw is rotated by the handle and simultaneously acting on the bar with a cutter that applies the division ruler, while controlling the spread between the applied divisions produced by interchanging the slide guides.

In FIG. 1 is a front view of the machine; FIG. 2 - top view of the machine; FIG. 3 - view of the machine in cross section.

The bed / machine is equipped with installed and along its rods 8.8, on which, using sliders 3.3 with fastening screws, guides 7.7 are mounted on the suporta 6, the latter is connected to the turntable 4, one end of which is hinged on the bed /, and the other is pivotally connected to the nut 5 of the lead screw 2, mounted in bearings across the bed / and fitted with a ratchet wheel W fixed on its end. The ratchet wheel tooth 70 engages with a pawl 75 connected by a handle / 2, on the axis 16 of which is placed PA The lec 77, which is included in the slot of the rod 9, mounted in the brackets of the bed 1. On the rod 9, there is a swivel holder 18 on it, carrying the cutter 77. The ha ha 13 is equipped with a pawl 19 that engages with the teeth of the ratchet wheel 20 located on one axis 27 with a disk 22 provided with adjustable stop lugs 25 arranged around its circumference, designed to interact with a hook 24 fixed on the axis 16.

M.E.

When using the machine, the ruler is attached to the caliper and the machine is activated, together with the handle 72, a swinging motion, i.e. turning her into that and the other side. When moving the handle forward, the pawl 75, acting on the ratchet wheel 10, reports rotation to screw 2, the nut 5 of which, turning the bar 4, informs the movement of the support 6 together with the ruler mounted on it. During the reverse movement of the handle 72, the finger 77, acting on the rod 9, moves it together with the cutter 77 mounted on it, causing it to be applied on the division bar. Adjusting the distance between the divisions applied to the ruler is done by swapping the guides 7, 7 of the suporta 6 along the rods 8.8, and the execution of the risks of the required length is accomplished by installing the stops 25 on the disk 22, organizing the return stroke of the handle 72.

The subject matter of the invention.

1. A manual machine for applying tick marks on the rulers, characterized by the use of a slide bearing a ruler and moved along the guides 7,7 by means of a turn bar 4, a linked nut 5 with a lead screw 2, rotated from the handle 72, articulated with the bearing cutter // barbell 9.

2. Use in the machine described in p. 7 at the ends of the guides 7,7 sliders 5, moved along rods 8,8. for rearranging the suporport in the transverse direction in order to change the interval between risks.
