H., Augsburg, Germany Application April 11, 1955, Serial No. 500,539
Ciairns priority, application Germany February 1, 1955 6 Claims. (Cl. 57-345) This invention relates to a device for securing the suction tube and its associated clearer roller to the machine frame of a spinning machine provided with a suction system for removing broken ends from the spinning machine and more particularly, from the lower fluted front roller thereof. It is known to provide below the lower fluted front rollers of the drawing frame, in addition to suction tubes for the broken ends, clearer rollers serving for cleaning the fluted rollers.
It is an object of the present invention to provide, without any constructional change, particularly simple means for mounting the suction tube and the clearer roller, so as to permit a simple mounting of the suction tube on all existing spinning frames of any type, and an easy removal and reinsertion of the clearer rollers during the working of the machine, without stoppage of operation, for the purpose of cleaning the clearer rollers.
With this and further objects in view, according to the present invention a mounting spring is arranged on each end of the suction pipe between the closed end face of the suction pipe and a suspension clip, for mounting the clearer, said mounting spring being swingable about a screw serving to secure the suspension clip to the end of the suction tube, and being adapted to be clamped by the screw in the desired position, this mounting spring moreover forming a bearing for the respective journal pin of the clearer roller.
It will thus be understood that in this arrangement no alteration of the clearer, nor the provision of additional fixing means, is required, since the screw bolts for the fixing of the suspension clips serve simultaneously for securing the mounting springs for the clearer. These mounting springs advantageously are bent in an approximately semicircular shape and arranged in such a way that the center axis of the journal pins of the suspension clips coincides approximately with the center, of the semicircular arcs formed by the mounting springs.
Other and further objects, features and advantages of the invention wiil be pointed out hereinafter and appear in the appended claims forming part of the application.
In the accompanying drawing a now preferred embodiment of the invention is shown by way of illustration and not by way of limitation.
Fig. 1 is a side view of the mounting members for the suction tube and clearer on the drawing frame of a spinning machine,
Fig. 2 is a similar side view, but showing the mounting members in their lower position, for removal of the clearer,
Fig. 3 is a top plan view in the direction A of Fig. 2,
Fig. 4 is a section on line 44 of Fig. 3,
Fig. 5 is a detail of Fig. 3 showing the end of the suction tube on a larger scale, and
Fig. 6 is a side view showing a modified form of fixing a mounting spring.
Similar reference numerals denote similar parts in the different views.
Referring now to the drawings in greater detail, and
hired rates P t Patented Mar. 4, 1958 ice first to Figs. 1 to 4, it will be seen that the two forward cylinders 1 and 2 of the drawing frame 26 of a spinning machine are arranged in conventional manner, for passage of the roving or thread 3 between the rollers. Mounted below the fluted cylinder 1 is a suction tube 4 with suction openings 5 connected through a branch 6 with a curved tubular member 7 which is longitudinally slidable in a rubber sleeve or branch 9 secured to the collecting channel 8 of the suction system of the spinning machine. Secured to the closed ends of the suction tube 4, by means of screws it are'suspension clips 11 each formed with a journal pin 12, by means of which the suction tube 4 is mounted or suspended in bearings 13 formed by a pair of spring arms 14 which are secured to the drawing frame 26 by screws 27, Fig. l. According to the invention a mounting spring 16 is arranged'on each end of the suction tube 4 between said end and the respective suspension clip 11, so as to be swingable about the screw bolt it) by means of which it can be fixedly clamped to the suction tube. In the preferred form of the invention as shown the suspension spring 16 is bent in an approximately semicircular shape and arranged in such a way that the center axis of the journal pin 12 of the suspension clip 11 coincides approximately with the center axis of the arc formed by the spring 16. Thus, with a relatively close mutual arrangement of the suction tube 4 and the clearer 15 there is obtained a relatively long arcuate spring arm 16 by which the clearer is urged against the fluted cylinder 1 in the direction of arrow B, in such a way that the journal pins 17 of the clearer cannot run out of the spring bearing 18 in an upward direction as a result of the rotation of the clearer. Advantageously the mounting spring 16 is formed with an upwardly bent portion 19 tor reliably preventing such running out in an upward direction of the journal pins 17.
In a practical embodiment the radius r of curvature of the mounting spring 216 is about 23 mms., so that the distance a between the centers of the suction tube and the clearer is approximately equal to r. With such proportions my novel mounting can be provided subsequently, without any alterations, on all spinning machines (with or without a lower belt or strap).
As will be seen from Fig. 4, the fixing end 16a of the mounting spring may be inwardly bent in an annular form and inserted in a cap 20 provided with a hole for the screw bolt it) and having a slot 21 for passage of the spring 16, so as to prevent the spring from turning in the cap 20. This construction also permits a single type of cap to be used for fixing and mounting the mounting springs 16 on both ends of the suction tube.
As indicated in Fig. 3, the parts are arranged in such a way that the annular part 16:: of the spring on tightening of the screw bolt 16 is urged by the cap 20 against the end face of the suction tube 4, whereby the mounting spring 16 is safely held on the suction tube in a predetermined angular position. Thus, the actually desired pressing force 3 by which the suction roller is urged onto the fluted cylinder can be produced by corresponding adjustment of the spring 16.
In the modification shown in Fig. 5 the end of the suction tube 4, or the screw plug 22 closing the same, is provided with a conical projection 23 on which the spring ring 16:; is clamped when tightening the screw bolt 10. By this conical clamping arrangement a very reliable and tight connection is achieved between the mounting spring 16 and the suction tube.
My novel mounting can be provided not only in connection with suction tubes having a conical projection 23 or a cylindrical projection 24, but also in connection with suction tubes having plane end faces. As shown in Fig. 6, a solid disc 24 having a hole for the screw bolt and, on its side facing the tube end, a slot or groove 25 for clamping the end 16!) of the spring, may also be used for fixing the mounting spring 16.
Fig. 1 shows the suction tube and the clearer in their operative positions. In order to remove the clearer for cleaning, it is merely required to pull the suction tube 4- scmewhat out of the branch 9', in such a way that he parts come into the position shown in Fig. 2, in which the length by which the suction tube 4 is held in the branch 9 (or in a saddle which is not shown) is reduced from the amount A of Fig. 1 to the amount A, of. Fig. 2. 1 In this position the clearer 15 can easily be removed from the bearings 18, cleaned, and reinserted, without any stopping of the machine being required. The parts may now be restored to their operative positions shown in Fig. 1, by merely raising the suction tube somewhat and sliding the tube 7 into the branch 9, so that the journal pins 12 again snap into their spring bearings 13.
While the invention has been described in detail with respect to a now preferred example and embodiment of the invention it will be understood by those skilled in the art after understanding the invention that various changes and modifications may be made without departing from the spirit and scope of the invention and it is intended, therefore, to cover all such changes and modifications in the appended claims.
