PAUL RAMSEIER ATTORNEY Patented Sept. 27, 1960V DEVICE FOR BRINGING 'STACKED TRAVELLERS ONTO THE RINGS F RING SPINNING FRAMES Paul Ramseier, Pfailkon, Switzerland, assignor to Briicker A.G., Pfattikon, Switzerland, a Swiss irm Filed Nov. 22, 1957, Ser. No. 698,286 `Claims priority, application Switzerland Dec. 8, 1956 7 Claims. (Cl. 29-207) The present invention relates to a device for separating travellers arranged in a row on a guide rod or rail and for pushing the separated travellers onto the rings of ring spinning and/or ring doubling frames.

In the known devices of this kind, the travellers arranged in a row on a guide rail are directly pressed by a compression spring against av stop, which is adjustably fixed on the casing of the device so that it can be set to suit travellers having different widths; `The separating and pushing `of the foremost traveller which is pressed against the stop, is effected in the known devices by a tongue which can be shifted or swivelled and is moved in Vthe gap between the stop and the guide rail. Since the tongue in the known devices may not be wider than the gap between the stop and the guide rail, which corresponds to the width of the travellers to be installed, it is necessary to replace the tongue whenever the device is to be used with travellers of a different width, and this is really very troublesome. Further, in the existing devices, the bearing means of the tongue is constructed in such a way that neither lateral deviation of the tongue,

separating the foremost traveller and pushing the latter i onto the ring.

Another advantage of the device embodying the invention resides in the fact that, when the traveller is being pushed onto the ring, the tongue at first moves yalong 'a straight line until the open ends of the traveller thereby rolled onto have engaged over the usual T-shaped projection of the ring, and thereafter the forward end of the tongue moves along a curve, an inclined plane, or the like in the upwardly inclined direction, so that the traveller is the ring. Such movement of the tongue effects rotation through 90 of the traveller made of hard steel wire, and absolutely excludes the possibility of breakage of the traveller or `any other mishap, even when the finest travellers are being pressed onto the ring. Since a traveller inserting device is especially valuable when replenishment of the stock of travellers can be in the accompanying drawing, where:

nor alteration in the direction of motion thereof, is pos- 1 sible when pushing the travellers onto a ring. These existing devices also fail to provide any means for holding, in an inoperative position, the compression spring which normally urges the stack of travellers against the stop so that the supply of travellers on the guide rail can be replenished. In the known devices the foremost of the stacked travellers is only held firmly by being pressed against the stop, and no means are provided for otherwise determining the position of the traveller accurately before the latter is pushed onto a ring.

The object of the present invention is to provide a device for inserting the travellers, which is very handy, light and easy to manipulate, and which also offers the advantage that a great range of different sizes of travellers can be inserted with one device without requiring the changing of any parts thereof.

According .to the invention, this object is accomplished by mounting the stop on the movable tongue so that the stop can be shifted transverse to the direction of movement of the tongue. With this arrangement, the tongue can have the thickness needed for the greatest width of traveller to be installed therewith. At any time, the movably arranged stop covers the superuous width of the tongue, so that the only part of the width of the tongue which is yleft free to act on the traveller is that corresponding exactly to the Width of the traveller. Since the stop is mounted on the tongue, it is also possible to'mount the tongue resiliently for permitting deviation of the latter in the direction of the guide rail, so that the stop can be set a distancevfrom the end of the guide railwlich is smaller than the width of the traveller to be installed and the foremost traveller is still engaged and accurately located by the guide rail while waiting to be pushed onto a ring, and the tongue is laterally deflected, along with the stop, duringrits movement for effected quickly, certainly and very simply, the device embodying the invention has a pressure-piece which is loaded with a ,spring and carried on a slide rail arranged parallel to the traveller guide rail, to normally act upon the stack of travellers on the latter with'the pressure-piece being retractable to a stop and there free to be turned outof the range of the guide rail so that an additional stack of travellers can be installed on the guide rail. In this position the pressure-piece is held firmly by a notch, so that it is possible to install the new travellers, without having to remove parts of the device. v

Referring initially to Figs. l-5, it can be seen that, between two handle parts 1 and 2, there is secured a plate 3 which projects, at its front end, out of the handle 1, 2. The plate 3 forms a rigid element and has a recess .4 which `can beset onto the edge of the ring 5 of a ring spinning frame, as illustrated in Figs. l, 6, 7 and 8. At one side of plate 3 there is a slider 7 `forming a movable element and having a forked end projecting out of the handle 1, 2. An operating handle 9 is pivotally mounted on a pin 8 in the handle 1, 2 and. has a rounded extension 10 engaging in a slot 11 inthe slider 7. With one hand the handle 1, 2 can easily be held and the operating handle 9 simultaneously pressed towards it, so that the slider 7 is pushed towarlifthe for carrying a stock ofV front. A spring 12 always tends to return slider 7 to its position of rest, as is illustrated in Fig. 1.

At the front end of the plate 3 a pipe 14 is xed above the recess 4 by means of a screw 13 (Figs: 2 and 8), and a sleeve 15 is longitudinally displaceable on the pipe 14. A screw 17 extends through a longitudinal slit 16 provided in the pipe 14 (see Fig. 9), and connects the sleeve 15 to a sliding block 18, which is displaceable within the pipe and against which one end of a compression spring 19 acts. The other end of spring 19 abuts against the closing screw 20 at the end of the pipe remote from plate 3 (Figs. 1 and 2). Thus the sleeve 15 is constantly forced toward the plate 3 by means of the spring 19. A stock of travellers 21 (Figs. 6, 7 and 8) is pushed-on a guide rod 22, which extends parallel to pipe 14 and is rigidly connected by means of a strap 23 to the pipe 14 and thus to the plate 3. The row of travellers 21 forming the stock is spring-loaded, in that the sleeve 15 has a lug 24 (Figs. 1,3 and 10), formed with an opening adapted to receive the guide rod 22 and normally pressing against the traveller 21 furthest from plate 3. In order that the sleeve 15 along with the lug 24 can slide past the strap 23, the sleeve and the lug are provided with slits through. which the strap 23 can pass (Figs. 1, 3 and 10). The foremost traveller 21 bears against a stop 25 carried by the forked end of the slider 7, the stop 25 being transversely adjustable relative to the direction of movement of the slider 7 so that the distance from the end 26 of the rod 22 to the stop 25 can be varied to suit the width of the travellers 21. The adjustable mounting for the stop 25 includes a screw 27 which is rotatably carried by the forked end of slider 7 and secured against axial displacement by a pin 29 engaging tangentially in a groove 28. The screw 27 extends threadedly through stop 25 and the end of screw 27 has a plurality of milled notches 30, for engagement by a spring loaded detent ball 30a disposed in a small bore running radially to the screw, so that one can only turn the screw by overcoming a certain resistance exercised by the ball. In this way, inadvertent displacing of the stop 25 is prevented.

The end 26 of the guide rod 22 projects beyond the plane of the sliding contact of the plate 3 and of the slider 7 into the gap between plate 3 and stop 25 by a distance equal to a fraction of the width of that gap in order to prevent the foremost traveller lying against stop 25 from inadvertently falling out through this gap. However, in order to avoid obstruction of the displacing movement of the slider 7 by the end 26 of the guide rod 22 projecting into the gap, the slider 7 is pressed resiliently against the plate 3 by means of a leaf-spring 31 (see Fig. 5), and the end 26 of the guide rod 22 is chamfered. Thus, when the slider is moved forwardly, the front end of the slider 7 is deflected laterally, and rides across the projecting end 26 of rod 22. The lateral deflection of slider 7 away from plate 3 increases the gap between stop 25 and end 26 of rod 22, so that a traveller can be pushed therebetween.

In order to facilitate the pressing of the travellers 21 onto the ring of the ring spinning frame, the front end of the slider 7 is made to move upwardly during a nal portion of its forward movement with a traveller being pushed in front of the slider, as can be seen in Fig. 7. In this manner the front end of the slider is made to deviate from a straight-line movement, so that it elects the necessary quarter turn to be made by the traveller about its axis during installation on the ring 5, and thus it is possible to install even quite fine travellers which would be pressed out of shape if the slider moved only in a straight line. It is advantageous for the slider 7 to have a small projection 31a (Figs. 6 and 7) in order to achieve the desired upward pressing of the traveller. This upwards movement of the end of the slider is caused by a pin 32 which is fitted on the front portion of the slider 7 (Figs. l, 5, 6 and 7) and'is guided in a curved guideway 33 machined in the plate 3. A second pin 34, arranged beside the slot 11 on the slider 7, reciprocates in a straight guideway 33a (shown in broken lines on Fig. l) in the plate 3, so that during its forwards and backwards movement the slider 7 undergoes a small tilting movement round this second pin 34.

The position of rest of the slider 7 can be adjusted by turning an eccentric pin 35 (Fig. l) which is rotatably mounted -in handle 1, 2 and is engageable by the back end of the slider. It is thus possible to adjust the rest position of slider 7 so that the traveller 21 lying against the stop 25 is situated at only quite a small distance away from the front end of the slider and thus, without being turned in any way, is from the beginning of the moment of the slider pushed with its opening opposite to the edge of the ring 5. If, for example, thicker or thinner travellers have to be brought onto the ring spinning frame, the position of rest of the slider can be correspondingly adjusted by turning the eccentric 35. If the new travellers are at the same time wider or narrower, the stop 25 is then also adjusted by means of the screw 27. Because of this possibility of adjustment, about thirty different sizes of travellers can be inserted. The smallest width of the travellers may, for instance, amount to 0.40 mm., and the greatest width may amount to about 2.6 mm.

Another possibility of adjusting the device to accommodate different travellers is shown in Figs. 13 to 15 in which the guideway 33 in the plate 3 is replaced by a guideway 46 in an intermediate plate 45. The intermediate plate 45 is arranged between the handle part 1 and the plate 3, and has two oblong holes 47, through which pass two screws 48, by means of which the intermediate plate 45 can be rmly clamped between the plate 3 and the handle part '1. An opening 49 is formed in the plate 3, yso that the pin 32 xed on the slider 7 can extend through opening 49 to engage in the guideway 46 in the intermediate plate, while the pin 34 only reaches into a horizontal oblong hole 50 in the plate 3.

If the screws 48 are slightly loosened, the intermediate plate 4'5 can be displaced longitudinally through a distance determined by the length of the hole 47, such displacement being eiected by turning an element having an eccentric middle portion 51 located in an opening 52 in the intermediate plate 45, and opposite end portions 53 which are seated rotatable in holes in the plate 3 and in the handle part 1 respectively. Since the spring 12 tends to pull the slider 7 and also, through the pin 32, the intermediate plate 45, to the right, as viewed in Figs. 13 and 14, the turning of the eccentric 51 produces a reciprocating movement of the intermediate plate 45. In this manner the guide way 46 can be moved toward or away from the stock of travellers on the guide rod (not shown) so that, when the slider 7 presses a traveller onto the ring 5, the movement of the front end of the slider along an inclined path occurs nearer to, or further away from, the ring 5. It is thus possible to suit the device very iinely to travellers of different size. After the intermediate plate 45 has been adjusted, the screws 48 are tightened again, so that the intermediate plate 45 is held immovable.

If the stock of travellers on the guide rod 22 is exhausted, or if travellers of another size have to be inserted, the sleeve 15 is drawn to its position most remote from the plate 3 and is locked there by turning the sleeve about pipe 14 so that the screw 17 enters a notch 36 at the end of the slit 16 (Fig. 3). The effect of this manipulation is to bring the lug 24 of the sleeve 15 behind the rear end of the guide rod 22 and to swing it out laterally, as can be seen in Fig. l0. Thus new travellers 21 can be pushed over the rear end of the guide rod 22. IPreferably this new stock of travellers consists of an orderly row of travellers that can be pushed onto the free rear end of the guide rod and is held together by some means that can be destroyed. Such means can be an adhesive essais strip running along the stack of travellers Aand torn away from the latter after the travellers have been pushed onto the guide rod 22. Another destructible means for holding together the stack of travellers may be an adhesive which holds the travellers together only so strongly that they can be detached singly from the stock of travellers by the slider 7 when the operating handle 9 is drawn towards the handle parts 1, 2. After the destructible means has been removed, it is important that no remainder of it be left sticking to the travellers.'

When stacksnof travellers are employed that are held together by aL wrapping of paper or a foil of synthetic material it is preferable to arrange at the free end of the guide rod 22 a small knife 44 (Fig. 3), which cuts the wrapping Vwhile the travellers are being pushed onto the guide rod.

In Fig. l2 another embodiment of the invention is illustrated in which, instead of the guide rod 22, a twopart traveller guide is provided having a rear part 37 which is detachably held between a front part 38 and -a holder 39. When it is necessary to replenish the stock of travellers, the part '37 can be changed for another identical part serving as a magazine and on which a stock of travellers has already been arranged. The holder 39 can be pushed to the rear for a short `distance along pipe 14, so that the part 37 can easily be introduced between the ends 4i) of holder 39 and front part 38 or withdrawn from between them. The front part 38 is connected to the pipe 14 through the strap 43. Also in this embodiment, a spring-loaded sleeve `41 is movable along pipe 14 and has a lug y42 pressing against the rearmost traveller in order to force the stock of travellers continually toward the plate 3. The user can either keep several parts 37 serving as magazines with travellers arranged in rows on them for use with the embodiment of Fig. 12, or stacks of travellers which are held together by a destructible means can be stored for installation on the guide rod 22 of the iirst described embodiment of the invention. In both embodiments the stock of travellers can be seen `at any time, so that the stock can be replenished before it is completely exhausted.

Because of the fact that, in the described device, the slider 7 slides along close to the plate 3 and beyond the end 26 of the guide rod 22 or of the part 38, and that by simply turning the screw 27 the stop 25 can be adjusted over a wide range in accordance with the width of the travellers, the `device is adoptable for travellers of very different sizes, without requiring the replacement of any parts. Only when installing very small or very large travellers will it be desirable to use another traveller guide 22, or 37, 38 respectively. The changing of these parts is eifected by loosening the screw 13, `after which the pipe 14 can be removed, together with all other parts attached to it.
