UNITED STATES MAX AUERBACH, OF HAAG NETI-IERLANDS TEXTILE MACHINE.
Application filed December 17, 1924, Serial No. 756,576, and in Germany October 17, 1924.
This invention relates to a textile machine and inorepartlcularly to a locking device for the feeder of shuttle changing devices and has for its object to provide an ar-' rangement, whereby the feeder is prevented from throwing a shuttle out of its, supply container, if the means for receiving the shuttle are not properly adjusted. By this invention, therefore, the advantage is obtained, that a preventive means is provided which will render impossible that several shuttles will pass at the same time into the shuttle box. Furthermore a pushing of the shuttles of the same will be made impossible by this invention.
This problem is solved according to this invention by keeping the feeder in locked condition by means of a pawl, which during the preparatory operating position of the plate or lifting device serving for the control of the locking arm connected with'the front wall will be released by a releasing device actuated by the weft fork or by the feeler, whereby the lowermost shuttle will come into the position ready for operation, while during backward motion of the lay the condition of locking is again established by a swinging of the aforementioned locking arm.
In the accompanying drawing there is represented diagrammatically an example of carrying this invention into effect. Figs. 1 and 3 of the drawing show the several parts in their locked positions in a side view and a top view respectively, while Figs. 2 and 4 are similar to Figs. 1 and 3, the parts being in their released positions.
The front wall 11 of the shuttle box 14 is attached to the lay 12 which is adapted to oscillate with the lay arm 40, on a shaft 13 which is journaled rotatably in the side wall of the shuttle box 14. A pivoted rear wall 15 is adaptedto be brought into a diagonal position in the shuttle box by any suitable mechanism upon exhaustion of the weft to eject the spent shuttle. Secured to the shaft 13 is a lever 16 with a pin 17 which engages the hooked lever 18. The hooked lever 18 is oscillatably journaled to the loom at 19 and has a locking arm 56 and an arm 55, which is adapted to be held down by a pawl 54 until the latter is released by the weft fork 20 mounted on the shaft 10. The filled shuttles 53 are stored in a magazine having an opening at its lower end to permit the lowermost shuttle to fall out prior to being pushed into the shuttle box. The pusher 31 which conveys the new shuttle into the shuttle box is given its operative movement against the action of a spring 57 by the pusher lever 31 operated by suitable means on the lay, such as that shown in my Patent No. 1,566,136
granted December 15, 1925, during the change operation. According to the invention the pusher 31 is so formed and arranged that, as shown in Figure 1, it closes the magazine in its intermediate position, so that the shuttles in the magazine rest on it. In this position the pusher is re tained by the locking arm 56 which is so connected with the hooked lever 18 that it comes into a locked position as shown in Fig. 1, when the lever is in its raised position. The connection between the locking arm 56 and the lever 18 is, preferably, a loose connection. The arm 55 supports the locking arm 56 so as to raise the latter. The pawl 54 is pivoted on the pin or bolt 54 and engages the arm 56, thus limiting the downward movement of the hooked lever 18.
If, however, when a pick is lacking, the weft fork is actuated and the pawl 54 thereby released, the hooked lever 18 is drawn into its lower position, by the spring 21 as shown in Figure 2, in which on return of the lay, it engages the pin 17 on the drive lever 16 of the front wall 11 of the shuttle box, in order to begin the change operation, wherein on the rearward beat of the lay the spent shuttle is ejected, and the front wall 11 of the shuttle box is raised while the pusher lever 31' is not operated until the succeeding forward beat of the lay. A further result of lowering of the hooked lever 18 is that the arm 56 connected therewith and raised by the arm 55 releases the pusher 31 from the action of its spring I 57, which pulls it back so far, as shown in Fig. 2, that the bottom of magazine 50 is opened and the lowermost shuttle can drop in front of the pusher 31.
On the frontward beat of the lay the lay engages the pusher lever 31 and advances the pusher 31, which pushes the shuttle 53 under the raised front wall 11 and into the shuttle box. After the change operation the hooked lever 18 is again raised to such extent, that the pawl 54 can reengage the arm I 55 thereon and retains it in the position as shown in Fig. 1. The
I claim:
In a shuttle-changing device for looms, a lay, a weft-fork, a shuttle box, the front Wall of said shuttle box being liftable, an actuating lever connected with saidfront Wall, a hooked detent lever, a pawl, said pawl being releasable by the fork and adapted to hold the detent lever in raised position, said detent lever subsequently to the release of the pawl engaging the said actuating lever during the rearward beat of the lay, a stationary shuttle magazine having an open bottom, a feeder adapted to be moved by the forward beat of the lay for introducing the new shuttle into the shuttle box, and a detent arm connected with the hooked detent lever and adapted to be lifted by said detent lever, said arm being so positioned with respect to the feeder to hold said feeder in an intermediate position in which it closes the bottom opening of the shuttle magazine.
In testimony whereof I have hereunto affixed my signature.
MAX AUERBACH.
