SPINNING AND Twrsrrne MACHINE.
Application filed April 7, 1927, Serial No. 181,776, and in Switzerland and Germany April 16, 1926.
This invention is concerned with improvements in spinning, twisting and the like machines, particularly with improvements of the actuating mechanism of the feeding and stretching portion of such machines. In former machines of this kind a pinion gear comprising a considerable number of pinions wasarranged between the main actuating shaft and the feeding and stretching mechanism of the machine for operating the same. Only the pinions adjacent to the feeding and stretching mechanism could be exchanged, wherea'sa modification of the remaining gear train could not: beeifected. It therefore has already been proposed to use chains for the actuation of. the feeding and stretching mechanism instead of pinions which however permitted a va 'iation of the numbers of revolution of the stretching and feeding mechanism by a special speed changing de- "vice interposed between the chain gear and the feeding and stretching mechanism.
It is the purpose of this present invention to permit a speedchange without any variation of thejlengtli cf the chain by having the chain transmitting members supported on an adjustable support adapted to be rocked around the axis of the main actuating shaft and to be further rocked over 180 C. aroundan intermediate belt or pin normally locked at the main bearing shield of the machine in order to reverse the speed ratio transmitted between the main actuating shaft and the feeding and stretching mechanism.
In the drawing which illustrates a pre ferred embodiment of my invention Fig. l is a front view of the main bearing shield of a double-sided spinning machine having chain transmission, the cover of the main bearing shield being omitted for the sake of clear illustration,
Fig. 2 is a side view of Fig. 1,
- Fig. 3 is a front view of the chain a greater scale,
4 is a section on line 44: of Fig. i,
Fig. 5 is a section on line 55 of Fig. 3.
g Y The spindles 1 are actuated by worm gears .2 the driving. shaft 3 of which is supported in the spindle bearing. aand driven by an v actuating gear 6' located within the main gear on hearing shield 5. The gears G are actuated, respectively, by a main gear 7 and shaft 8, as illustrated, which aredriven by pinions 9 shafts 10 co uplings 11 and a motor 12, tne pinions 6, l and 9 being preferably located in casings 14 closed by detachable lids 15, the whole main bearing shield 5 being preferably closed by a detachable cover 1b as shown in Fig. 2. The feeding and stretch lng mechanism indicated at 17 is operated by pinion 18 and pinions 20, 21 as shown, which may be adjusted within a slot 19.
A transmission of the actuating power from the shafts 8 of the main gears 7 to the pinions 20, 21 is effected by a chain 22 passing over sprockets 23, 24- supported by pins 25 of a double-armed lever 27. The pins 25 are carried by lugs26, the lower pin 25 being arranged in alignment with the shaft 8 of the main pinion 7 and soasto rotate therewith and the double-armed lever 27 is supported on a bolt 28 arranged centrally of the axes of pins 25 and guided in a circular T shaped slot 29 of a lug 30. This slot 29 is concentric with pin 8 and lower shaft 25 and the lever 27 can be locked by bolt 28 in its operative positions as will be readilv understood. Upon a 180 rotation of lever 27 around its bolt 28 the upper sprocket will be located in axial alignment with shaft 8 so that it can be coupled with the main pinion 7 for simultaneous rotation as will be explained herein after.
In order that the sprockets may be operated by shaft 8 and pinion 7 the pins 25 are at the embodiment illustrated provided with square recesses 31 engaging with the corresponding square ends of shafts 8 so as to rotate therewith. The pins are further provided with extensions adapted to carry and actuate a pinion 82 meshing with pinion 21 in order to drive the feeding and stretching mechanism. The pinion can thusbe readily dismounted. when the position of the sprockets is to be reversed, it being understood that that sprocket only which is the upper one at a given adjustmentwill have to carry the pinion 32 on its pin 25. In the embodiment-illustrated the ratio between the two sprockets 23 24 is 2: 3. This ratio may of course be varied as required, care being taken however that the length of chain 22 remains constant.
From the foregoing description it results, that upon loosening bolt 28 the lever 27 can be turned around the axis of shaft 8 so as to disengage the pinion 32 from pinion 21. T he pinions 20, 21 and 32 respectively can now be exchanged In order to provide fine adjustment of theworking speed of the feeding and stretching mechanism, whereupon the engagement of the pinions is reestablished and the lever 27 locked by means of its bolt 28. \Vhen coarser adjustments are required bolt 28 is again loosened and the lever 27 shifted forward so as to disengage the lower pin 25 from shaft 8. The lever 27 can now be turned over 180 around its bolt 28 and the chain drive reestablished and locked as will be readily understood, whereupon the ratio between'the driving and driven parts is reversed. Theupper and lower sprockets can thus be reversed in a very quick and simple way, so that the number ofintermediate pinions 32,30, 21, 20 can for a given range of speed adjustment be considerably reduced.
