Description

By means of the proposed frame for concluding the composing form, it is intended to achieve a reduction in the rash and destruction of the infiltration of the wiping dirt between the material of the set, thus achieving purity of the analysis. In addition, with the help of a frame, in the opinion of the inventor, it is possible to save covering material, twine, and working time by removing the laces and retaining them after washing.

In FIG. 1 is a side view of a frame for an enclosed typesetting side view, with a partial cut; FIG. 2 - the same, top view; FIG. 3 shows a section along the line A B in FIG. 2; FIG. 4 - frame detail; FIG. 5 and b - the second version of the frame for concluding the typesetting form; Fig, 7 - the same, the third option.

The frame for concluding the set consists of four (identical in design) sliding metal rails 1, connected at their ends to each other in a quadrangular frame by T-shaped fasteners 2. Each rail 1 consists of two halves, of which one has two strips 3 T -shaped section, and another, one strip of 4 H-shaped section (Fig. 3),

Both of these halves are inserted one into the other, forming one sliding rail 1. The side bar is attached to the side bar 4

plate 5, on top of which a spring-loaded lever 6 is fastened with a tooth 7, a spring 8 and a cape 9. On top of the bar 3 there is a gear rack 10.

We separate the end fasteners 2, separate the two adjacent laths 1, which are at an angle of 90 relative to each other, similar to the same pair of rails 1, press on the ends of the levers 6 with a pair of rails 1 and throw capes 9 on them. 7 levers 6, come out of the teeth of the toothed rack 10, spread the rails 1 to the desired set format. In this way, they put one pair of slats 1 on the mullion and begin to recruit or typeset into it. After completing the set, fasten the second pair, also of the rails 1 apart, with the first T-shaped fasteners 2, release the lever 6, fold the capes 9, and shift the frame to the minimum format of the set, push the rails on top and on the right, without moving the left and bottom rails with a set. The tooth 7, while compressing the frame, due to the inclined plane of the teeth 7 and 10 and the springs 8, jump over the tooth of the gear rack 10.

The opposite sides of the same teeth 7 and 10 are vertical, which, thanks to the same springs 8, press the tooth 7 to the tooth of the rail bar 10, following
