Description

Manual carpet weaving machines with a vertical base are known, including shaft and batting mechanisms and two horizontal shafts for the main threads, the lower of which is equipped with tension screws.

The disadvantage of such machines is their long-term simple with manual insertion of the main threads, the income of I1II up to 10-12 hours. on each basis, and the cost of this operation is two working 20-24 man-hours. labor.

In the described machine, this disadvantage is eliminated by the fact that the operation of the sowing is mechanized.

The machine has the feature that sprockets are mounted on the ends of the horizontal shafts, covered by infinite chains, inconsistent and immobile bar, spring-loaded coil with main yarns and spindle, periodically rotated by means of a rack and pinion mechanism for moving the p-head with

eye, loosely installed on the guide rod.

FIG. 1 shows a machine, front view; ma fig. 2 is a view along arrow L of FIG. one; in fig. 3 is a view along arrow B in FIG. one.

The machine is assembled on a welded bed /, the side racks of which are made of tler's well and provided with supports for the upper horizontal shaft 2 and the lower shaft 3 for the main threads.

The upper shaft bearings are rigidly fixed to the frame, and the lower one is passed through the elongated windows of the struts and interact with the tension screws 4. At the upper ends the screws are worm shchestren, coupled with the worms. 5, equipped with pas one end

The sprockets 7 are put on the ends of the axes of the horizontal shafts 2 and 3, on the rolling bearings, sprockets 7, pairwise covered by two endless chains 8 Gal, 1. The top asterisks are one cent.

gears 9, which are in engagement with gears W of the roller And, located in the bearings of the frame. The roller // is equipped with a handle 12.

Instead of two links, both chains 8 are equipped with P1 levers, in the supports of which a spindle 13 for a nut-driver with an eye, freely mounted on the guide rod 14, and also an axis 15 fixed to one of the glands with coils main threads mi. One of the flanges clamps the coil with a spring placed in the cavity of a fiber and so on cup brake l that is tightened by means of a nut / 7, which ensures uniform tension of the main threads during rotation of the roller // handle 12. Rotate the spindle 13 p feed the nut-driver along it is the interaction of the gear on the end of the screw with the upper and lower combs rigidly mounted on the frame (not shown in the drawing). For tensioning the chains 8, two sprockets 18 are used, the axes of which are mounted on sliders extended from the guides of the bed.

The machine mechanism of the machine is a frame 19 and 20 with toothed racks interacting with the bristle axes 2 and 22.

A batten-comb 23 with a counterweight 24 is driven from a knife and a pedal 25.

To rotate the upper shaft 2, there is a handwheel 26 and a corresponding gearbox.
