10 shaft motion.
When the shuttle is driven by means of a picker, the movement must be extraordinarily strong whereby the whole machine is sub jected to a strong jarring and to considerable wear and tear of the machine parts. Thus, very heavy webs cannot be produced on this type of machine, and the shuttle must be passed through the shed by hand. Moreover, in weaving by means of the picker, the weft could not be woven in with the desired degree of tension.
All these disadvantages are overcome by the present invention and, according thereto, the shuttle is positively guided through the shed.
In order that the invention may be clearly understood and readily carried into effect, reference is made to the accompanying drawings, which show diagrammatically and by way of example a construction in accordance with the present invention.
Figure 1 is a diagrammatic illustration of the parts serving to effect the movement of the shuttle which is shown in the middle of its path.
Figure 2, drawn to an enlarged scale, shows the shuttle in the same position as shown in Figure 1.
Figure 3 shows the shuttle shortly before reaching its middle position.
1 is the slay having the shuttle 2 guided thereon, and which contains in the usual manner the weft thread of wire, not shown in the drawing, because it forms no part of the present invention. A shaft 3 having a crank at is arranged transversely of the loom 1, and in the middle of the slay. Two connecting links 6 are pivoted 011 the crank pin 5 of crank 4:, said links lying behind one another in Figure 1. Two bell crank levers 8 338,757, and. in Germany February 17, 1928.
are rotatably mounted on fixed pins 7 and are pivoted at one end to the connecting links 6. The opposite end of each hell crank lever 8 is connected by a rod 9 with a rod 10, whose lower endis connected by means of a link 11 to a stationary part 12 of the loom frame.
The upper ends of rods 10 are pivoted to the pickers 13 which are guided on the slay 1 like the shuttle 2. These pickers 13 have a thrusting edge 1% and carry a catch or coupling hook 15.
The shuttle 2 has a nose 16 on each end turned towards the pickers 13 and rearwardly of said noses, crank levers 17, 18, whose inner arms 17 lie in the same plane as the catch or coupling hooks 15 which are reciprocated with the pickers 13. The arms 18, of said crank levers, which project upwardly are connected. by links 19 with. a vertical lever 20, pivoted at the middle of the shuttle 2 and whose lower end is formed as a toothed sector 21, having only a few teeth, adapted to cooperate with a toothed stop 22 secured in the middle of the slay 1.
The operation is as follows.
Assuming that the shuttle 2 is in the outer most right position (Figure 3), crank pin 5 assumes its uppermost position. The crank lovers 8 are in the position indicated in dotted lines in Figure 1, and the pickers 13 in their outermost position.
The toothed sector 21 and the crank 1cvers 17, 18 arrangerfl on the shuttle 2 have been rotated in a clockwise direction in the preceding stroke of the shuttle to the right, and they now assume the position shown in Figure 3. Rotation of shaft 3 causes the pickers to move towards one another, so that the right hand picker 13 pushes the shuttle 2 in front of it, through its thrusting edge l t (Figure Shortly before the shuttle 2 reaches the middle of the slay, the toothed sector 21 engages toothed stop 22; as soon as the shuttle 2 has slightly moved past the middle of the slay, the parts 17, 18 19 and 26 are moved into the opposite position, that is, the position symmetrical with that shown in Figure 3.
In this movement, the catch hook 15 of the right hand picker 13 is raised by the arm 17 of the right hand crank lever 17, 18, so that it is prevented from engaging behind the right hand nose 16 in the subsequent outward movement of the right hand picker 13 to the right; Simultaneously, the catch hook of the left hand picker 13, which, on the movement of the shuttle past the middle of the slay, had slidden over the left-hand nose 16, engages behind the nose 16, in the movement of the left-hand picker to the left, thus drawing the shuttle 2 into the left-hand position.
In the next rotation of shaft 3, the left hand picker 13 now pushes on the shuttle 2 by means of its thrusting edge 14, toward the middle, where the toothed stop 22 is again engaged by the toothed segment 21, which latter causes a displacement of parts 17, 18, 19 and 20 into the position of Figure 3, so that the shuttle 2 is released from the left-hand picker 13 and coupled with the right-hand picker 13.
Such a positive guiding ofthe shuttle 2 through the shed by a rigid gear allows the proper tensioning of the weft thread or wire and prevents any vibration or jarring of the machine. I
Having now described my invention what I claim as new and desire to secure by Letters Patent is:
1. In a loom particularly adapted for weaving heavy metallic fabrics, a slay, a shuttle guided on said slay, two pickers adapted to be imparted a reciprocating motion along said slay, locking means having cooperative parts on said pickers and said shuttle, respectively, and adapted to couple said shuttle with said pickers, a pivotal member on said shuttle adapted to release one of said locking means or the other according to its operative angular positions and stop means on said slay, in the path of said member, for pivoting said member from one operative position to the other.
2. In a loom particularly adapted for Weaving heavy metallic fabrics, a slay, a shuttle having a pivoted lever at its centre, two crank levers pivoted at its ends, respectively, links for connecting the inner ends of said crank levers to one end of said pivoted lever, projections on said shuttle adjacent the outer ends of said crank levers and out wardly thereof, two pickers guided on said slay, hooks pivoted to said pickers respectively and engageable with said projections and the outer ends of said crank levers for the elevated position of the latter, means for imparting a reciprocating motion to said pickers along said slay, and a stop member on said slay, in the path of said pivoted lever.
3. A loom as claimed in claim 2 wherein said pivoted lever has gear teeth adapted to name to this specification.
