Description

The BASIC patent describes a hand loom, the stands of which are connected by sticks to a shaft placed on them, jja, which is a finger that engages with the bataya finger. The shaft presses with eccentric fists on the stumble steps of the belt. To release the shoulder lock fingers on the shaft act on the latch. Under the action of springs, shoulder straps hit the races of the shuttles and are pulled with their cords into their initial position. In the additional patent, the transfer of movement to the shaft is carried out by means of tg, levers and criminal steps from the shaft, which receives movement from the batan. A leverage system was used for the first lock, one of which, in contact with the impact, lever, rotates the last one around the axis and thus transmits the other two levers of the drive train system that hits the race, which drives the shuttle.

FIG. 1 shows a schematic drawing of a hand weaving machine; FIG. 2nd side view; FIG. 3-device and position of the combat mechanism before hitting the shuttle on the left side of the machine; FIG. 4-position-Second combat mechanism (idle), corresponding to the position of the combat mechanism in FIG. 3; Fig. 5 shows a device for a camshaft rotation mechanism; FIG. 6-view it in playa.

The machine consists of a frame 1, on which a batane 3 is fixed in sub-supports 2, rocked by a working weaver with the help of a handle 4 and a step 5 (Fig. 1, 2). At the ends of the yoke 3, brackets 6 are rotatably mounted on axles 7 of the sleeves 8, serving for the shuttle shuttle, which are acted upon by a system of levers 11, 10 and 9 rotatably mounted on the brackets 6. The strips 8 are brought to the tilted position by springs 14.

At the bottom of the machine on the beam 15 (Fig. 1) there is a distribution mechanism for transmitting the movement to the remixes and shoulder straps 8, consisting of a shaft 16 rotating in bearings 17, a ratchet 18 fastened on it and sitting free on the shaft 16 levers 19 sec. dog 21, dropping into the ratchet teeth 18. Lever 19 is provided with a slot 22, a criminal step 25 and a spring 23, the dog 21 is a spring 34. In addition, the lever 19 tons of the 20th arm is connected to the battery 3, to the product roller), the dog 19 lever captures for the corresponding conductive ratchet tooth 18, rotating the latter on the proper portion of the circumference

depending on the amount of remise), the throttling may be changed by moving the bolt 26 over notch 22 and changing the length of the string 20.

When the batana 3 moves forward (to the main roller), the lever 19 with the spring 20 and the spring 23 is pulled downward. The stroke length of the batana 3, as a result of the dog 21 slides along the teeth of the ratchet 18, in Kyunts the movement of the batane 3 stops, dropping ratchet tooth 18

With each movement of the batan back, turning on a certain part of the revolution, using eccentric cams 24, mounted on the shaft, presses the keys 25, mounted, on the shaft 16 and connected to the other ends I with the shafts 27, to change the position of the latter, depending on the weave, the arrangement and order of pressing of the cams 24 on the keys 25 is established.

The ends 27 and the keys of the left and right parts of the machine are connected by means of 27, with the other end fastened to the distributors of the combat mechanics.

The device of the distributors can be seen from FIG. 3 and 4. In order to periodically activate the distributors, a system of levers 28, 29, 30 was applied; One of the levers 0 is connected at its end with a flexible rod 27, and the other with a spring 31, at which the latter always strives to keep the system lever 29 in the bo-hfig position. 3), thanks to which, when the crank 3 moves forward to the main roller, the end of the lever 11, meeting with the impact lever 29, rotates the latter around the axis 12, thereby transmitting the movement through the levers 10 and 9, shoulder strap ke / 8, hitting the race. 32, which transmits the blow to the shuttle 33. Racing 32 is equipped with a spindle 34, thanks to which the races can move in a horizontal direction in the longitudinal groove of the bat 3, with the bat 8 after the impact on the race 32 moving back to the bottom of the groove following the shuttle. 33, with it. Racing returns to its combat position. The shock of Shuttle 33 from the opposite stbandon.

With the above description (Fig. 3), the end of the key 25, with which the ha 27 is connected, is raised, due to

what The bend of the ha 27 is not tensioned and the lever 29 is located in a vertical combat position. At this time, the end of the other key 25 (Fig. 4), to which the second bend is connected, ha 27, is lowered down, as a result of which the ha 27, pulling, puts lever 29 in an inclined position, and the lever, 11 passes without touching for it and not making a stroke with a stroke 8. On the next movement of the batane 3 to the turning one in Aliyu, overload occurs on the levers 29.- The described connection of the tg with the side-tapping keys 25 can take place only with a different weave. In the case of multi-rim interlacing, it is necessary to install special keys and simple steps on the ends of the camshaft 16 to turn on and off (alternately on each side with each movement of the battane) shock levers 29 by means of the above-described flexible ones, tons g 27.

In order to facilitate the movement of the bat and increase the impact of the batts 8, the bat 3 is equipped with retracting springs 35. The product is wound onto the roller 36 automatically by means of a ratchet wheel 37 fixed on the shaft 36 and connected by means of a pawl with a spring with a lever freely seated on the shaft 36 38 with a load of 39. The density of the goods is regulated by shifting the load 39 along the corresponding recesses 4p. After certain interruptions of time, by lowering the lead lever to the lower extreme position, it rises to the extreme upper position.

FIG. 1 the dotted line indicates | 1 ti gi 41, fastened at one end with the free end of the lever 11, and at the other end. With a bar of 1 frames and a machine, by means of which it is also possible to bring in. the action of batches 8, in which case the valves (Figs. 3 and 4) are not set, and the batons 8 are set in motion simultaneously with. each advance of the batana 3. At the same time, when the batana approaches the front extreme position, the ti 41 pulls up, as a result of which the levers 11, transmitting this movement to the drives, 8, move at the same time at both ends of the batana hit on racing 32

shuttle 33. When the batan 3 moves back, the springs 3, the springs 14 put the batons 8 again into the firing position, etc.

The subject invention /

1. Modification of the hand-weaving machine according to patent No. 821, characterized in that, for the purpose of periodically switching on the combat mechanism, rods 27 are used, connected each at one end with a system of levers 28, 29 and 30 (Fig. 3 and 4), and others the end is with keys 25 (Fig. 1) sitting on shaft 16, which also serves to transmit movement to the shaft through t 20, levers 19 with doggie 2 and protruding steps 25 and receiving movement from the bat 3 by means of a ratchet 18, and for throwing hook systems applied levers 11, 10 and 9, rotatable mounted on brackets b the ends of the yoke and the operating taps 8 when in contact with the lever v29 systems 28, 29 and 30.

2. With the use of a ratchet 36, swiveled by means of a lever 38 and supplied with a load 39, with the aim of winding cloth, as described in paragraph 1 of the machine tool.
