Innovations in twisting machines.

Patented in the German Empire on March 8, 1878.

This invention initially ordered in the use of twisting machines with dowel pin and with wings for threads of two, three, four, five, six and more wires in strong and weak Numbers, whereby when the thread is stopped or torn off, the unwinding of the threads from the bobbins stops immediately will; stopping happens automatically and at the same time with the rotation BEZW. Move the spindle and pressure roller.

Fig. Ι shows the design of these perfected Twisting devices with drop pins; 2 shows the front view; 3 shows the section through a friction washer through which motion is imparted to the spindles; Fig. 4 a Side view; Fig. 5 shows the innovations; the drop pin acts here on a spindle in front of and on a spindle behind the pressure roller; Fig. 6 Aufrifs of Kötzerröhren and small spindles for the same.

A, Figures 2 and 5, is the frame of the apparatus with a cross piece B for the spindles and a cross piece C for the rollers; in the crosspiece B spindles D are attached, each of which is provided with an attachment E on which a ring F is placed in order to prevent wear. A whorl G todt runs on the ring, it is provided with a plate H at the top; the whorl is set in motion by a cord and cylinder. On top of the whorl G and the spindle D a clamp / with weight is attached, which is provided with a neck piece J and an angle bracket K. The clamp / contains an incision Z in which a linch pin M, which is fastened in the spindle D , functions. A round plate N is fastened under the bracket / and , when it comes into contact with the whorl G, when it is in motion, generates friction which gives movement to the spindle by means of the pin M; the clamp / with weight is in contact with the whorl during twisting and becomes free of it as soon as the thread or threads O cease or ripen; the clamp is lifted by a wedge P , which is covered with leather or wood. The wedge is attached to the end of a lever R , which in turn is attached to the lever E by means of a pin. The lever R goes through a guide T, which is attached to a plate U on the crosspiece B ¹ . The lever S is provided with the projections V which move in the guide plates W ; these are attached to a cross piece X which is held by a carrier Y which is attached to the bearing Z. The lever S has the arm A \ which is provided with the bearings B 'in which the pressure roller C ¹ works; Furthermore, the lever S is provided with rods or tail frames D ' which move freely in the openings E ' of the plate end ^{7 ';} these plates are attached to the arms G ^{1 of} the Y supports. The threads of the bobbins H 'run over a rod / ¹ and through guides J ¹ , which are formed on the needles or wire hooks K ¹ , these move freely in the coulisse L ' of an oscillating plate M ^x ; this plate swings on the pins iV ^{1 of} the supports / "of the plate F '. The oscillating plate is provided with a counterweight Q ' and a cover R ', which the latter holds the needles K ⁱ in place; is on one side of the counterweight There is a protruding piece S 'which carries a hook lever T ' connected to the lever S ¹ ; on top of the tip of the lever 5 is a rod IP , which is provided with a coulisse guide V ¹ , this guide through whichever the threads pass through it keeps them separated between the rollers, so that they are perfectly coiled and twisted regularly.

The inventors employ a tension plate W ⁱ for the bobbins, in which a peg X ⁱ with an angular head is attached which fits into a hole made in the bobbin; this head prevents the bobbin from lifting due to the tension in the thread. The tension of the threads keeps the needles K ¹ raised, but if one or more threads run out or tear, the needles in question fall down and come into contact with a flywheel Y ', which gives movement to the oscillating plate M ', so lift raise the hook lever T ', Fig. 1, and free the lever, forcing the pressure roller C ' to slide forward; As a result, the lever .S ^{1 is put} into effect and the wedge P is pulled inward on the angular enclosure K; this lifts the clamp / and pulls it from the

Whorl away, which stops the spindle ... j. ' The whorl runs away, even if she does ■ * '"spindle is brought to a standstill, which prevents that the cord is lengthened.

The inventors also set the spindles in motion by using angular friction wheels and attaching a lying shaft A ″ to each spindle in front of or behind the same, and on the same a wheel Z. This wheel is provided with a ring B ² over which a Ring of leather or wood C ^{2 is} placed, this is held in place by a thin ring D ² and screwed tight with screws E ^2. The wheel is held on the corrugation ^{2 by} means of a screw G ^2. The surface or the angle of the wheel Z 'moves on the surface or the angle of an innkeeper with weight H-, which is provided with a neck piece J and an angular enclosure K. The whorl is provided with an incision L in which a pin M , which is fastened in the spindle D , functions When the surfaces of the wheel and the host are in contact with each other, they transmit the rotational movement to the spindle through the intermediary of the pin M, the drop pin acts in the same way as described above, if the thread stops or breaks and lifts the whorl H ² from contact with the wheel Z ', whereby the spindle is stopped.

In the case of threads with two thick wires, which require a strong, perfectly coiled and regular twist, the two ends of the thread are first given a small, two or three turns on the drop pin and then a further turn by turning the bobbin I ¹ , , Fig. 5, with the slightly twisted threads on the spindle J- the spindle K ~ , which works behind the rollers. This spindle is constructed with short wings L ² , which have no transverse piece. The spindle K ' ¹ is mounted in a spindle cross piece M and a cross sleeve N ² , and set in motion by a friction control wheel Z ^1. This wheel acts on the surface of a landlord with a weight of O-, which, however, is constructed without a neck piece or enclosure; the whorl is provided with an incision L , in which a pin attached in the spindle K ^{2 engages.}

The threads of the bobbins / ² go through the guides P ² , which are mounted on a rod Q ² ; this is attached to supports R - , which are attached to the coil carrier S ² . If you use the spindles K ² , the spool carrier Y ^{2 is} withdrawn and can be set aside without removing the spindle K. When the thread ends or ripens, the drop pin M ¹ acts on the lever S and on a lever T " which is attached to the lever S ; the lever T ² is provided with a wedge U ² and is guided in a guide V ^2; the wedge U ² acts on the surface of the host O - and at the same time that the wedge P stops the spindle D , the wedge U ² stops the spindle K ² by lifting the whorl O ² from the wheel Z ¹ .

The Kötzer beater tubes W ¹ are guided over short spindles X ² , which are mounted in the bobbin holder S ^2; the beater tubes are in the part which enters the spindle, and for cotton kötzer the part Z ^{2 is} constructed on which the kötzer is put. In this way the muds are easily attached, the threads going through guides A ³ and around a spool B ³ which are covered with wool to obtain the tension required to keep the needles of the drop pins in place obtain.

We claim the exclusive right to carry out our improvements with the justification, shape, material and dimensions of the components of the applied Changing apparatus.
