In the proposed machine, the upstream and downstream base carrier 1 is suspended from the Flexible link 4 between the parts of the bed 2, 3, and this link goes along the rollers 5 and is provided with a counterweight 6 at the other end corresponding to the weight of the base carrier 1. On a dovetail shaped Part 7 of the base is fastened with brave parts 8, fitted with hole 9, chain brackets 10, with the brackets being held in the correct position during installation of the machine by means of setscrews 10 (Fig. 2). Above the brackets 10 in the plugs 13 there are hung tubular guides 12 provided with heads 11, the lower ends of which reach the upper parts of the brackets 10. The heads 16 of the pistons 17 adjoin their guides 14 under the action of springs 18 (Fig. 1). partly entering pistons 17 and partly into cylindrical guides 19, into which pistons 17 are inserted. The tension of the springs 18 and the pressure with which the guide rollers 14 adjoin

The brackets 10, and further to the fabric, can be settled by the levers 20 rotating in the sub-carriers 21, creased to the parts of the bed 2, 3. The levers 20 are connected to the setting knobs (Fig. 2), for holding which in certain positions locking devices, not shown in the drawing, such as a dog, and corresponding sludge teeth are provided.

To deflect the guides 12 for the base are the supporting bars 23, 24, 26, moved in the horizontal direction in the guides 27, attached to the parts of the bed 2, 3. These supporting bars are provided with tips 28, 29, 30, 31, the faces directed upwards which lie in the same plane, and their ends have hook-shaped bends directed to the outside, to which springs 33 are attached, attached to the clamps 32 from their side. The ends of cord rods 36, 37 attached to the levers 34, 35 are hooked to hook-shaped bends supporting pl NKI and move through them in the direction opposite the spring action. The removal of the levers 34, 35, arranged by the doctors on the axis 39, resting in the sub-bearings 36, is carried out by means of cam shchibs 40, 41 (Fig. 6, 7}, the fists of which are fixed on the shaft 42.

The levers for driving the battal arms 45 rotate from the axis 47, which is at rest in the spars 46, so that with their tips 48 they can pass between the guides 12 and reach the middle axis of the weaving machine.

The axis 47 is provided with a double-arm lever, one shoulder of which is arranged to engage the spring 50, which is attached by the other end to the hook 51 (FIG. 2). The other arm 52 (fig. 3, 8) is connected by a joint to a rod 53, which is connected to the crank lever 56 by means of the crank lever 54 and rod 55, which is driven from the eccentric 57, which also goes to the shaft 42, which are diametrically opposed. each other.

The input of the refined material is made by means of a weaving shuttle 60 (Fig. 5),

having a clip 61 on its back to set the weft material. The shuttle is thrown back and forth by percussion devices arranged on both sides of the parts of the bed 2, 3. These percussion devices have one cup 65 each. Cup 65 has races 67 (Fig. 4), supplying ;: with sleeve 68 in the form corresponding to the end of the weaving shuttle 60. Racing 67 is provided with a check 68 guided by the grooves 69 of the cup 65 parallel to each other, closed on the other side by a lid 70. The spring 71 is at one end attached to the race 67 and the other to the insert 71 and can be turning the set screw 73 on. For cup 65, there is an eccentric 74, which with its fist 75 engages aa extended down the check 68. The eccentric is tightly mounted on the shaft 76 driven by the gear train 64 (Fig. 1) from the shaft 77, which in turn is driven into rotational motion from the shaft 42 by means of a chain drive 78.

Between the cups 65 and the tips 28, 29, 30, 31 of the supporting bars 23, 24, 25, 26 a hook 60 lies on the bridges 80. After pushing into the jawl, the weft material is pushed out of the bracket 61 by means of a pusher 82 pushed to the beam 81. Each frame is thus arranged in one of such ejector pushes, which eject only the weft thread that is connected from the opposite side of the frame.

The process of making reed tissue is as follows. First, the carrier 1 is raised so that the staples 10 can become a melgutz guide rollers 14. Then the chain stems are sucked from the head through the guides 12 into the holes 9 of the staples. After that let the loom in the course. It is necessary first of all to move the cord string 36, so that the supporting bars 24 and 26 with their tips 29 and 31 strike the supporting bars 23 and 25 with their tips 28 and 30, and they fold the guides 12 into their extreme

oblique positions, so that each second base is bent forward, and the bases lying between them are folded back. During the movement of the support bars, a weaving shuttle 60 supplied with a weft (weft thread) to the right bridge 80 is handed over to the right bridge 80 and hit by a race 67, which at the same time under the action of the cam 74 takes up its extreme position. After moving the tips, the eccentric 74 releases the key 68, and the hook 60 flies, iod the action of the spring 71, on the other side of the loom, and it slides between the guides 12 along the extended tips of the support bar. As soon as the weft material is inserted into the throat, it is released by the ejector 81 from the clevis 61, and the weft material is pressed down or nailed with the help of the cams 58 when the heads 48 of the batan levers 45 are used. After that, the shuttle is supplied with a new weft material and due to the further rotation of the shaft 42 34 returns to its original position, with the supporting strips extended forward under the action of the springs 33 returning to their initial positions, at the same time tensioning pull rods being pulled. At the same time, the support bars 23 and 25 are set in motion by means of the lever 35, as a result of which the guides 12 are folded to their other extreme positions by means of the tips 28 and 30. As soon as the guides 12 have reached these new end positions, the shuttle 60 with the new weft material is pushed back by the other percussion device onto the side of the shift, and the percussion device moves as described above, and the weft material is pushed out of the bracket 61 by the ejector placed on the other frame . After weaving the weft material, the levers for the weft presses the last inserted material to the previous one and simultaneously press down the carrier 1 down by the thickness of the weft material, and the base also moves forward through the guides 12. As soon as the brackets 10 are pressed, the latter pressed against the fabric.

In another form of implementation, both parts of the frame 90 and 91 are connected between themselves by crossbars 92, which are fixed to the steps, which serve as steps, and crossbar 93 (Fig. 11) connecting their upper ends. The left-hand part 90 of the frame carries a drive shaft 95 attached to the supporting parts 94 attached to it. At one end of the latter there is a handwheel 96 and at the other end.the idle shaft 97, as well as the drive pulley 98 and the spur gear 99. 95 is shown by an arrow P (FIG. 9). The spur gear 99 is in engagement with a counter-wheel 101. Fixed on the shaft 100 of eccentric disks. The gear ratio of both spur gears is 1: 1, so that the eccentric disks 102, 103, 104, 105, 106, 107 mounted on the shaft rotate at the same speed as n the drive shaft 95. At one end of the latter there is a manual flywheel 96, and at the other end is the idler pulley 97, as well as the drive pin 98 and the spur gear 99. Each eccentric disk each corresponds to one eccentric lever 109, 110, 111, 112, IZ, 114, rotating debris for rest. in sub-carrier 94, axis 108. The disks are provided with guide slots 115, 116, 117 , 118, 119, 120 (phage. 19, 20), each of which includes a guiding pin located on the respective eccentric levers.

Shaft 126 is rotated in the 90.91 nods of the beds125 attached to the parts. Their drive is made from a pair of spur gears 127, 128, a gear ratio of 1: 2. The wheel 128 is connected tightly with the eccentric wheel 12E, so that both of them rotate in the bearing pins 130; the eccentric wheel 129 is engaged (with a ratio of 1: 1) with an eccentric wheel 131, which rotates together with a bevel wheel 132. The bevel wheel 132 is in its clutch (with a gear ratio of 1: 1) with a bevel wheel 134,

which is wedged on the shaft 135, rotating in bearings 136, 137. A oblique tooth 138 wheel mounted on the shaft 135 is in engagement (with a ratio of 1: 1) with the same wheel 139 wedged on the shaft 95. Thus, the shaft 128 is / Ket make two turns while shafts 95 and 100 each make only one turn.

The sprockets 140 are fixed to the shaft 128, the distance of which can be varied by moving them accordingly, while the side rolls are mounted on the shaft: the arms 141 hang down so that they can swing, and the adjusting rings 142 prevent the lateral movement of the balls , their arms 141 on the shaft 126, and the mounting rings 142 fix it to move in the axial direction. Loose kachuyush kovtsy; phs levers are connected between themselves by axis 144, on which freely rotating sprockets 145 are mounted, against lateral movement of an expensive sludge mounting rings 146, at which stage there is one link 148, equipped for gripping and dropping weft material, with a bracket 149 ns of the bent spring wire and the fixed angle 150 (Figs. 15, 16) so that the material captured by it is tightly sewed, supplied for further feeding and then can be easily released again.

The swinging arms 141 are tilted away from the eccentric disk 103, which, by means of the lever 113, drives the last link 152 attached to the latter by means of the transfer lever 151. Parallel to the other end, the clip 153 is pivotally connected to this end bearings 154 shaft 155 (Fig. 10) jammed on this noslenem. On the shaft 155, the levers 156 connected by means of the transfer levers 157 with the axis 144 are wedged, to the free ends of which are attached, besides the transfer levers 157, one lever 158 each, which is; serve to drive the shaft 159. This latter rotates in the bearings 160 and carries

two weft levers 161, which can be reset sideways. A table board 162 is mounted between these latter, supported by beams 133 supported on rods 164, with which bearings 160 are connected. Weft levers 161 could also enter the grooves contained in the board

STOLG).

Vertical guides ;; The base carriers 1 are fixed to the EE base part, 81. The head parts 166 of the base carriers have rollers 167 guided by the guides 165 and are connected to each other by connecting rods 163 and spacers 139. The interconnectors 168 and spacers 103 carry support 170, 171, on which are parallel bars 172. The latter serve for Iomes; glasses 173 are placed on them, into the openings of which a base is inserted at one end. These cups are fastened with nuts 175 and have shifting hooks 176, the tips of which 177 are bent so that they, iodine by the action of springs 178, are inserted into the end of the base.

Above the glasses 173, the base moves along the guide 180, which, together with the tips 181, hang on the supporting forks 182, 183, opposite each other, the ends of which are so reinforced mutually on the rods 184, 185 that the ducks pass through to the supporting forks 182,183. The rods 184, 185 of the vehicle rest on the beams 186, which are fixed on prisms 187, supported by brackets 188, strengthened, in turn, on parts of the 187 front prisms

Nina SO,

warheads 190 and rear warheads 191 are mounted with the possibility of iredvizhezhia. The front warheads 190 and the rear warheads 161 are connected to each other in pairs by connecting rods 192, 193 and carry combat plugs 198, 197 on connecting in the same way the warheads 1E4, 195. These last YARs serve to swing the throat forward and back the stems with the help of the guides 180.

To allow the formation of the throat, the battle rods 194, 195 have the ability to move relative to each other.

to friend. This movement is achieved with the help of levers 196, 19E (Fig. 9.11), having fingers 200 at their free ends, which enter between the guides 201 of the front head portions 199 or, respectively, the guides 203 of the rear head portions 191 The levers 199 are seated on a shaft 204, having levers 208, 207 at both ends, of which the first lever 208 with a finger 208 at its free end slides along a groove made in the rail 210, fastened on a vertical mt 209, while the other end of the lever 207 with its finger 211 each time leans back with a finger Chaga 207 at the same distance to the groove in the lever 212. The lever 212 is mounted on the same axis with the right lever 198. The extension of the same groove along which the slider 208 enters is included in the side bearing 213 (Fig. 17, 18) on the lever 214, so that this lever, like the lever 206, leans back 209. The lever 214 is connected in its movement with the left lever 198, so that both the levers 198 and 199 of the second 209 are simultaneously moving, therefore also bars 194 and 195 approach each other and move away from each other again. Lifting and descending of the gi 209 originates from the eccentric disk 105 by raising and lowering the eccentric lever 112, the free end of which is connected to the thrust 209 by the transmission lever 215.

Since the guides 180 must alternately cross between the stalks to form a pharynx, the latter, and with them the stalks should alternately fold back the fabric in front and outside the area, for example, first, third, fifth and so on. With their stems, they should be folded back, and then, after entering the duck back, the first, third, fifth, and so on. The guides should be folded back, and the second, fourth, etc., guides forward. For this purpose, combat rods 194, 195 are made not only movable towards each other and back from each other, but also in their longitudinal direction and, moreover, simultaneously, but in the opposite direction, so that

The time, as one boom shtanga moves from left to right, the friend moves from right to left. The movement is made each time at a distance a (Fig. 9) between the axis of the guide 180.

The eccentric disk 107 is used to move the military rods 194 in their longitudinal direction, the eccentric lever 114 pivots out the guide groove 120 of which. The free end of the lever 219 is provided with a finger 220 (Fig. 9), which enters the left head guides 190 and tilts the lever 2G9 causes longitudinal movement of the yoke 194. Similarly, the yoke 195 moves in its longitudinal direction from the eccentric shaft 103 from the movement produced by the guide groove 116 of the eccentric lever software, which The articulated arm leans with it by means of a transmission lever of 223 tons ha 224, and with its help also a crank lever 226 swinging in bearing 225, the free gear between the guides 220 (Fig. 17) located on the left head part 191, so that when folding crank arm 226, rod 195 moves in its longitudinal direction. Since the rods each time must move only in one direction or the other in the transverse direction to the extreme polio, the guide grooves 116, 120 are so arranged that the eccentric levers at one turn of the eccentric discs 103, i07 either lift or press down, so that the return movement of the boom rods to the position preceding this occurs only during the second revolution of the corresponding eccentric disk. The distance of the battle forks 193, 197 from the battle shangs 194, 195 is two times larger than the distance a axes of the guide 180 (Fig. 4). Since each boom must use combat forks to fold back every second stem, in the same way, the combat forks of both combat rods are positioned relative to each other in such a way that when pushing the combat rods forward into the square fabric, the combat forks of one rod

enter the gaps of the other rod.

Above the base carrier T there are guide rollers 230, 23 (Fig. 21) for directing the stems first and then the tissue. Of these, the last roller 231 rotates in the direction of movement of the bearings 232 and is pressed against the springs 233 to the guide roller 230.

The motor 235 with the transmission lever 236 is connected to the eccentric lever 11, which is driven from the guide groove 117 of the eccentric disk 104. This heavy bar serves to throw away the lever 237, which is wedged on the shaft 238, rotating in bearings 239 on the back side of the base 90, 91. On the shaft 238, the levers 240 are wedged, with which the connecting rods 241 are articulated. These levers at the other end are mutually connected by a pull 242 for hammers. Both ends of this thrust for the hammers enter the guides 243, so that their upward and downward movement is forced. Tight 242 for hammers tightly with d t bodies 2J5, bearing rods 244.

With the aid of a pull 246 connected by a transfer lever 247 to an eccentric lever 10E, on which the eccentric disk 102 acts and by means of the lever 248, the shaft 240 for the fingers is driven. At its ends, the levers 250 (Fig. 22), with which the transmission levers 251 are articulated. With these transmission levers 251, the corresponding slider 252 moves back and forth along the guides fixed on the parts of the frame 90, 91. In these latter the shaft rotates 254, bearing in the installation 1X rings 255, fingers 256. On the shaft 254 there are springs 257 arranged on both sides, one end of which is fastened to the corresponding rod 258 on the shaft 254, while the other end is adjacent to the counter prop 25E than shaft 254 is induced Press the prop 230 on it to the counter 25E. The number 231 (Fig. 11) denotes onors located in front of the machine and serving for the plant1- and the weft material of the bed, with interconnected help of 262 parts

the frames 263 and the rods 264 mounted thereon for separating with tufts of weft material, and the parts of the frame 233 are covered with wire weave 285 with large holes forming the table.

The method of operation of the machine in another form of implementation is as follows. The initial position is the position shown in FIG. 9-12, in which the weft material assigned to the weft is captured by the squares 149.150 and is already vertically raised above the open at the top of the pharynx formed by crossing the stems (fng. 10, 11). With the further action of the machine, the weft material with the help of transferring pen 147 iodzodits top from between the guides 180. When this material is near the bottom end of the guide 180, the axis 144 from the part of the guide groove 119 of the eccentric disk 103 flips forward a little, so that the ducks protrude forward from the area, the fabric of the stems is removed from the squares 14E, 150 and remains in the throat. By further moving the chain 147, the swinging of the swing arms 141 is kept at its maximum value until the squares 149, 150 are near the table board 162. The eccentric wheels 129, 131 are so arranged that the transfer chains 147 then reach their lowest speed when the chain link 148 are provided in front of the board of the table 162. As the axis 144 advances forward, the levers 161 swing the movement into the fabric area. They attain the greatest swing at the moment when the cnp 148 link is in front of the table board 162. Due to this, it is possible to insert the weft material lying on the table board 162, using the levers 161, between the squares 149, 150.

At that moment, when the duck reaches a position lower than that in which 244 are out of action, pulling ha 242 for hammers, iodine, by the action of the eccentric disk 104, begins to move downwards. In this case, the haul for hammers is so pushed forward by the guide 243, that the rods 244 enter between the sweep 180 over the weft. Nod blows these cams released

Meanwhile, from the squares 149, 150 |

the duck is pressed down, and he is placed in the designated for him to receive; 1 shed over the duck, before | entered. Pressing down under the impact of the hammers, at the end of their journey, returning the eccentric disk 104 back to the ready position, the supply of the fabric is down, and under pressure from the cams, the fabric together with the coreplate T, respectively, the thickness of the weft, is pressed down. In order to avoid irregularities in the supply and production of the weave, first the base and then the weaving are guided by the guide rollers 230, 231. In addition, the founder T is equalized by the counterweights 2-36 suspended from the chain blocks that run through the rollers 268, 269 and strengthened to the head of the 268.

Upon insertion of the weft into the pharynx, the formation of a new pharynx follows, for which the stems by pushing the tubes 180 out of the plane of the fabric are advanced under the action of the combat forks 196, 197, after which the longitudinal movement of the military rods 194, 195 occurs as described above, so to the ready position for the next tilting of the rails 180.

In order to ensure that the guides are properly folded, the ends of both the forks 196, 197 and the supporting forks 182, 183 are provided with springs 270 (Fig. 23, 24), which are fastened at one end with screws 271, and at the other end with pins 272, The guides 180 are easily inserted into the forks. In this case, the springs of combat forks are somewhat weaker than the supporting forks.

The number of stems, as well as the distance between them, can be chosen at will. The arrangement of the stems corresponds each time to the arrangement of the guides 180, as well as the supporting forks 182, 183 or, respectively, the combat forks 196, 197. It is advisable to supply the rods 184, 185 and, respectively, 1S4, 195 with longitudinal slots 273 or, respectively, 274 for ti available on forks ridges 275 and, respectively, 276, as well as

dovetail-shaped grooves 277 and, respectively, 278, in which the fastening screws 279 for the supporting and combat forks are relocated.

The fingers 256 are needed only as long as the fabric is made with a greater distance between the webs. In such a case, before the duck is pressed downward by the impact of the rods 244, the fingers 25S, with the help of the shaft 254 on which they are mounted, with the help of the eccentric disk 102 simultaneously protrude between the stalks so far that the new duck does not fit on the intersection of the stems, and on fingers 256. In this way, the distance from one duck to another, corresponding to the height of the fingers, is obtained.

When the tissue is pushed down by the rods 244, the fingers 256, together with their shaft 254, rotate around the axis of the latter, move down a little, which prevents the fingers from advancing the tissue. Pressing the fabric downward, the fingers are again pulled out of the fabric with the eccentric disk 102, after which they return to their original position by rotating the shaft 254 under the action of the spring 257. If finger use is not required, they can be taken out of work by turning off, for example, the transfer rod 247 .
