ACT-TOTAL in Budapest.

The subject of the present invention is a weft insertion device for looms for horsehair and other such smooth and elastic thread materials and consists essentially in the fact that the weft thread, which is wound on a bobbin is into the Subject registered, and taken over by a second similar device, through the Tray is pulled.

The manufacture of horsehair fabrics

the ordinary loom was up until now

- basically impossible, because the horsehair, which for the time being tied together on a loom in the usual way for processing and must be wound on spools, a perfectly smooth, elastic, quite thick thread forms, so that

ao when it is placed in the compartment in the usual way, i.e. by moving back and forth quickly Protect, easily gets messed up when unwinding from the spool and thereby causes continuous malfunctions.

In the present device, this deficiency is eliminated by the fact that on a ordinary disc bobbin wound horsehair thread through a corresponding slowly moving back and forth bar entered a kind of plug-in contactors in the compartment so that malfunctions can be avoided and mechanical weaving can be done quickly and can go on quietly.

An embodiment of this device is shown in the accompanying drawings brought. The loom itself is generally constructed similarly to the known ones; accordingly are in the drawing only those components of the same are shown which are necessary for the understanding of the subject of the Invention forming devices are necessary. It should be noted that the shown Embodiment is to be considered only as an example. Furthermore, the loom provided with this device can easily for the production of a single horsehair tissue instead of two (as in the drawing) be set up.

Fig. Ι shows the drive of the drawer .. Fig. 2 is a front view of the new weft insertion device. Fig. 3 represents the. Device for driving the entry rod. Fig. 4 shows the device for releasing and connecting the bobbin carrying the weft thread from resp. with the entry rod. FIG. 5 is the front view of FIG. 4, while FIG. 6 an individual representation of the spindle carrying the coil including tripping and respectively. Locking device represents.

As can be seen from FIG. 1, the Drive the drawer in the usual way, so by crank or eccentric so that the Ark remains in its rear (drawn) position at rest until it is proportionate slow insertion of the weft thread into the shed is completed, whereupon they quickly and vigorously against the finished tissue

is snapped forward to immediately move back to the rest position. Accordingly eccentrics are in the embodiment shown ι on the drive shaft 2 of the mechanical loom keyed, which are designed such that at _^2/3 revolution of the shaft 2, the charge is 3 quietly in the position shown at ¹ Z ₃ of _a turn, however, forward to move against the finished fabric to immediately return to the rest position. Chains and weft threads are made of knotted or cemented or knotted and cemented horsehair and are in common Way on a chain tree resp. wound a spool. The coil is made here from a disc coil 4 (Fig. 2 and 5), which is pushed loosely over a spindle 5 (Fig. 6) will. Spindle 5 fits into the corresponding holes of the catch heads 6 the ends of the rods 7. These are slidably arranged in bearings 8 on the drawer 3 and are in a relatively slow reciprocating motion offset. This device consists of eccentrics 9 (Fig. 3), which on a below the drive shaft 2 arranged and driven by this by means of gear transmission · and the like second shaft 10 are keyed. These eccentrics are designed and with With respect to eccentric 1, this is the case with shaft 10 wedged, that while the drawer 3 is off the above-described movement (the stop) leads, the rods 7 connected to the eccentrics 9 in a corresponding manner stand still and vice versa. The drive of the rods 7, d. i. the shuffling back and forth the same in the longitudinal direction of the drawer 3, takes place by lever 11, which by corresponding Connections with the eccentrics 9 are in connection. This connection is such that lever II together with rods 7 at the same time opposite respectively. are moved from each other. Levers 11 are through connectors 12, which are firmly connected to the rods 7, connected to the latter. The rod heads 6 are given away with right-angled slots 13, which for receiving of pins 14 at the ends of the spindle 5 are used. When moving xler rods 7 The pin 14 pushes against one another at the free end of the spindle 5 into the slot 13 of the approaching rod head 6 and is therein by corresponding rotation of the Rod heads 6 held while the pin 24 at the other end of the spindle 5 is triggered from the second rod head 6 (see also Fig. 6), so that in the now occurring divergence of the rods 7 the spindle 5 together with the. the weft carrying coil 4 taken by the second rod 7 and through the compartment is pulled. To rotate the two rod heads 6 for triggering BEZW. Detection of the spindle 5 are arranged on the rods 7 lever 15, which by means of appropriate translation through an eccentric 16 (Fig. 4), which is keyed on the shaft 10, at the right time be twisted. It goes without saying that this arrangement can also be such that the right-angled slots 13 in the spindle 5 and the pins 14 in the bore of the rod ends 6 can be arranged, whereby an easier replacement of the coil 4 possible, is and at the same time it is prevented that the; Hang the thread on the protruding pins' if tin <l, operational disruptions ν arise. ,. . . ':' The individual operations described above now take place in the following order regularly in front of you: The drawer 3 strikes the last weft inserted - weft thread; Lever 11 together with the rods 7 are in their extreme position on the right and left at rest. The drawer 3 now moves backwards, the compartment is formed in a known manner; as soon as the drawer 3 has returned to its rest position, the compartment is also full . always open. There are now moving lever 11 to the rods 7 to each other, wherein the one, the coil 7 ^{( 'en} weft pulls 4-supporting rod in the tray. The free end of the spool 4 bearing spindle 5 now penetrates into the approaching rod head 6 in, whereupon the above-described rotation of the two rod heads takes place in the opposite direction in order to transfer the bobbin 4 to the second rod head 6 and, when the rods 7 subsequently diverge, to pull it through the compartment, whereupon the rods 7 in their outermost position to the right and come to rest on the left again and the beating of the inserted weft thread through the drawer 3 takes place. By pulling the weft thread through relatively slowly by the subject the deficiencies mentioned at the beginning are completely eliminated and through the rapid successive movement of the individual devices great loom efficiency achieved. • Patent claims:, i. Plug protection device for horsehair looms, characterized in that the bobbin (4) carrying the weft thread a rod (5) slid loosely rotatable is, .which the latter when moving the entry device towards the center of the Fabric alternately with the entry rods mounted on the drawer so that they can be pushed back and forth (7, 7) comes into and out of engagement to pull the weft through the shed. 2. Steckschützcneinrichtung for Roß- ■ hair looms according to claim 1, characterized in that the rod (5) carrying the coil is provided with pins (14) which engage in slots (13) of the heads (6) of the entry rods (7) and by turning the latter held ¹ respectively released. 1 sheet of drawings.
