Claims priority, application Germany June 4, 1957 The present invention relates to improvements in the setup of a plurality of spinning machines.

The machine frames and cross connections of old-type spinning machines were usually made of cast iron which meant a heavy load to be supported by the floor. On the other hand, the stability of the machine was very high, particularly if the machine had a low center of gravity. The progressive development of spinning machines led to a departure from cast iron frames and to the introduction of machine frames which substantially consist of commercial structural steel, or vertical rods or tubes or of sheet metal sections and are connected by horizontal braces. As long as such machines are made with 'a low center of gravity, the stability thereof will hardly be aiected. However, the narrower such a machine is made or the more a single center element only, such as a column, is relied upon for supporting a twosided machine and all the accessory parts thereof, the less will be its stability. In consequence of such low stability, vibrations may occur within the machine which will have an ill eiect upon the actual operation thereof, aside from the elect which such vibration might have upon the machine parts which are subjected to other vibrations even n the normal course of operations and which will thus withstand these stresses for a much shorter length of time. Since el'rorts are constantly being made to design machines which require the least possible space, the inevitable disadvantages of such designs should also be kept in mind. a

It is the primary object of the present invention to provide a new machine arrangement which will eliminate the above-mentioned disadvantages and will also furnish certain new advantages not contained in the prior machine assemblies.

According to the present invention these objects will be attained by providing the machines with elements which interconnect the machines and are disposed above the space required by the operators for servicing the machines, and which are also designed to support certain equipment or fixtures which are required for the operation of spinning machines.

The connecting elements according to the inventio are secured to the upper ends of the machine frames and preferably consist of connecting yokes extending from at least one machine to an adjacent machine. These connecting yokes may be secured either to each machine frame, or to every other machine frame in a staggered arrangement, or in any suitable order of succession in a direction vertical or at an inclined angle to the longitudinal axis of the machines.

The connecting yokes may be designed so as to support light fixtures, or to serve as a track for travelling bobbin frames, or as a track for cleaning or air-purifying means travelling above the machines.

"llhe present invention will now be described'in detail with reference to the accompanying drawings, in which:

Figs. 6 and 7 respectively show diagrammatic side views of a portion of a spinning machine provided with a running-off frame;

Figs. 8 to 10 respectively show additional basic setups for a plurality of spinning machines arranged in a row; while Figs. 1l and l2 show further details of the invention.

Referring to the drawing, Fig. l illustrates several spinning machines 1 of the same type which are substantially parallel to each other and are set up in a row. These machines are of a relatively small Width, as indicated in Fig. 2. The particular machines illustrated, for example, are double ring spinning machines, the stands 2 of which carry la support 3 and columns 4. The machines are equipped in the usual manner with spindles, a ring rail, thread guides, etc. The drawing frame 5 of the ring spinning machine, as shown at the left side of Fig. 2, is disposed Within the central longitudinal plane of the machine and is adapted to receive the sliver to be drafted from bobbin 6 through guide rollers. The double ring spinning machine -as shown at the right side of Fig. 2, is equipped with drafting frames S and 5", respectively, for each machine row, in order to illustrate that the arrangement according to the invention may also be used for machines of the type thus shown. Particularly whenever the machine stands 2 do not consist of a cast iron fname but are merely central supports erected on the oor, there exists the danger that, owing to the high spindle speeds employed at the present time, the machines will tend to develop vibrations which will then not only unfavorably affect the spinning process, but also the life of the machine parts. In order to avoid such disadvantages from the start, according to the present invention, said supports 3 carry columns 4 or the like which are interconnected by connecting yokes 7 forming la bridge over the service aisle between each two adjacent machines. Connecting yokes 7 may be arranged in different ways, as shown, for example in Figs. l, 3, and 4. According to Fig. 1, each first, third, iifth, and every other column of the rst machine is connected with the respective columns of the second machine by means of a connecting yoke 7, while each second, fourth, sixth, and every other column of the second machine is connected with the respective column of the third machine, while each first, third, iifth, and every other column of this machine is, in turn, connected with the respective column of the fourth machine, and so forth. As shown in Fig. 3, all the columns of each machine are connected with the respective columns of the adjacent machines. Fig. 4 shows a further possibility of arranging the connecting yokes so as not to extend in a direction vertical to the longitudinal axis of the machine, but lat an inclined angle to the latter, so that a zig-zag connection of the adjacent machines is attained, as indicated by the fully drawn-out lines. There is also the possibility of attaining a crosswise connection as shown in Fig. 4

. by the dotted lines. There are, of course, still other posin the provision of means for mounting other equipment and fixtures, required for a proper performance of the spinning operation.

Thus, for example, the inventionI permits a considerable improvement in the illumination of the work rooms. If the light fixtures are mounted in the usual manner at a considerable height above the machines, the results will be an almost uniform distribution of light within the room. However, this will also require a relatively large number of light fixtures or very strong light sources in order to obtain an adequate illumination at those points of the machines where such strong light is required for a proper operation. These points are primarily the drawing frames and thek spindles. Presently used light systems and most of the presently used types of light fixtures are, however, incapable of illuminating these particular spots sufficiently, particularly since the bobbin racks or creels of the machines interfere. The disadvantage may be entirely and very simply eliminated by means of the present invention, as illustrated, for example, in Fig. 2. The connecting yoke 7 is in this case designed in the form of an inverted U-shaped rail. The channel thus formed may receivev a lluorescent tube 8, the light of which will then be directed almost exclusively toward those points of the machine which require good lighting, that is, particularly, the drawing frame and the spindles. Because of the different manners in which the yokes 7 may be arranged between the individual machines, as shown, for example, in Figs. l, 3, and 4, it is also possible to provide the light fixtures in the most favorable positions.

Aside from being used for supporting the light iixtures 8, the connecting yokes 7 may also be employed` as a support of the bobbin creel and in such a manner as to permit an easier handling thereof from the machine oor. Such an arrangement will be of particular advantage if several rows of bobbins are arranged behind each other, because normally the most rearward row of bobbins is especially hard to handle. An example of such an arrangement is shown in Figs. 5a and 5b. If the individual machines are connected by connecting yokes 7 as shown in Fig. 3, one supporting creel 9 for bobbins 6 may be attached between each pair of adjacent connecting yokes 7. For this purpose, guide rollers 10 are provided in pairs at both ends of creel 9 whichv may be moved back and forth along =a suitable surface of the connection yokes 7. In this manner it is possible to slide a supporting creel 9 out of its operative position close to the drawing frame and in the longitudinal direction of connecting yokes 7 into the service corridor between the machines, so that any operation required in connection with the manipulation of the bobbins 6 may be performed much easier than it would be possible ifbobbins 6 had to remain constantly in a once fixed position close to drawing frame 5, as it is the case with the heretofore known types of bobbin creels. This new provision also does not result in any disadvantages to the orderly travel of the individual slubbing strands since the latter are guided to the drawing frame by means of guide rollers which are rigidly mounted on columns v4, no matter whether supporting creel 9` is in its operative position close to the drawingv frame or in pulled-out position above the service aisle,

Instead of supporting creel 9 holding individual bobbins 6, it is also possible to arrange in a similar manner for the suspension of draw-oh? creels holding several yarn balls on a continuous sleeve located between each pair of adjacent connecting yokes 7. Such an arrangement is illustrated in Figs. 6 and 7.

As shown in Fig. 6, connecting yoke 7 is provided with anarched section 11 which has a center of curvature coinciding with the axis of the roller 12 of the two guide rollers. The arched portion 11 of connecting yoke 7Y carries the drawo creel 13 for a spool 14y with a large number of yarn balls pivotably mounted thereon in the manner as customary in two-cylinder spinning machines. In such a manner it is possible to swing each time one of the draw-off creels located between two connecting yokes into the service aisle, which will considerably facilitate the handling of the spools. Fig. 7 illustrates another possibility of moving the draw-off creel 13 and spool 14 about the connecting yokes 7 which are located laterally thereof. Thus, the same advantages may be attained as with the previous embodiment.

In addition to the embodiments of the invention as described above, there is the further possibility of designing the arrangement according to the invention in still another manner by mounting mobile blowing units, known as such, or any other suitablecleaning unit, or for example, mobile air moistening units, so as to be movable along the connecting yokes or along rails which are mounted between the individual columns 4- and extend in the longitudinal` direction of the machines. Each rail may then support one of the units referred to, or several xtures or units may also travel thereon at short distances or greater intervals from each other, depending upon the purpose to be attained. The manner in which the rail may extend above the machines is diagrammatically shown in Figs. 8 to l0, which, however, illustrate only a few examples of the many possibilities in which such a rail may be designed. For example, the arrangement of the connecting yokes 7 according to Fig. 4 may yalso be designed so as to form a continuous track. This may be easily done by bending the individual con necting yokes 7 at a slight angle at their ends so that the upper surfaces of those portions of the connecting yokes which are located between the two ends are disposed at the same horizontal level. If, in addition, rails 15 are mounted on these surfaces in the manner as shown in Figs. ll and 12, the insertion of curved portions 16 into the track rails of the respective connecting yokes 7 will form a continuous track, permitting an uninterrupted travel of the blowing unit or other apparatus. The track for the blowing unit may thus be designed in accordance with the respective operating conditions, so that either at short or extended intervals the same section of a machine may be reached and, for example, be cleaned from adhering dirt particles by means of the same blowing unit.

Obviously, the manner of mounting the connecting yokes is not restricted to the presence of columns on the machines. In a similar manner, it is possible to utilize frame or creel portions of the machines or other supporting portions of the upper frame structure and to secure the connecting yokes thereto in a similar manner as previously described.
