G., Zurich, Switzerland Application Uctober 31, 1951 -Serial No. 254,044
Claims priority, lapplication Switzerland November f4, 1950 The present .invention relates .to :a process `and .a device for the twisting or doubling of `threads or filaments of any kind.
The process is characterized by :the fact that the thread or filament to betwisted is led freely fromthe creel bobbin downwards through the bore of a vertical spindle and, on its emergence from the lower end of the said bore, upwards against over pulleys to .a vwinding bobbin .arranged above the upper end of the bored yspindle and is wound upon the said bobbin.
The device for the performance of ythe twisting process in accordance with the invention possesses a vertical spindle with a bore extending from `end to end thereof, which spindle is so held elastically and =in a vertical position to a table by a clamping vdevice Athat it can :align itself to its ideal axis of rotation.
The object of the ,invention .is illustrated-in the drawing in the form of two preferred embodiments.
Fig. 1 is a sectional view of :a device with a rotating spindle, and
Fig. 2 is a sectional View of a device withva stationary spindle.
The vertical spindle 1 is provided with a bore 2 extending throughout the length of ,the said spindle, the shoulders yof which bore at either end thereof yare rounded. The thread 3 to be twisted is guided downwards from the creel bobbin 4 through `the said bore and is, on its emergence from the rlower end of the `said bore, taken over pulleys 5, 6, which are secured to the table slab 7 by means of straps .8, vertically upwards over a pulley 9, a deecting bar 10 and a threadiguide 11, -to the winding bobbin 12, which is driven by the roller 13.
In Fig. 1 the spindle 1 is rotatably mounted .in a ball bearing 14 and a roller bearing 1S Vboth of which ernbrace the said spindle. The said bearings are held in -the two ends of a bearing sleeve 16 having .a ange k17. rOn the inner face of the flange 17 are two elastic discs or collars 18 by which the bearing sleeve 16 bears the table slab 7 and by which it is clamped thereto. On the lower face of the lower disc or collar 18 is iitted a covering disc or collar 20 against which is braced one end of a helical spring 21, whilst nuts Z2 press against the other end of the said helical spring 21, said nuts being adjustable on a screw thread 23 disposed on the lower end of the bearing sleeve 16, so that the bearing sleeve 16 can be elastically clamped more or less strongly to the table slab 7. Screwed on to the extreme end of the bearing sleeve 16 is a threaded dise 24 against which a threaded cap 25 is screwed which closes the end of the bearing sleeve and through the crown of which only the end of the spindle projects. On the cap is an eye or lug 26 with a spring-loaded plunger 27 by means of which the spindle can be braked. The spindle 1 projects freely from the upper end of the bearing sleeve 16, and on the same, immediately above the roller bearing 15, is fitted the pulley or wharve 28 over whose lower part runs portion of the drive belt, not shown, whilst on the upper face 29 ofthe said pulley or wharve the creel y2,758,437 Patented Aug. 14, 1956 A2 bobbin, likewise not shown, is mounted. ICirclips 30 serve to secure lthe ball zand roller'bearings on the spindle 1 in the bore 31 `of the lbearing lsleeve v16, whilst a bore 32 is provided for puropses yof lubrication.
.In the embodiment of Fig. 2, a flange 33 is rigidly afhxed to the bored yspindle 1, on the lower .face of which flange elastic discs or 'collars ;18, between which the table slab 7 is held, are .again disposed. The lower .portion of rthe spindle 1 is provided :with :a screw thread on which two 'nuts 34 and a disc or washer 35 are fitted which press against a helical spring 36 which inturn is braced against the metal disc lor `collar in such a way that the spindle can be elastically clamped to the table slab 7. A sleeve 37 is rotatably mounted :on the `spindle 1 above the flange 33, 'which Isleeve has :at its lower yend a thickened portion .in Ywhich the roller bearing 37 is mounted. The cylindrical portion' located above the bearing serves as a .belt pulley or wharve for the drive of the spindle. Above lthis portion vis located a collar 38 and above this again an extension 39 on which is mounted a tube 40 which carries .the ball bearing 41 at its upper end. .Below and 4above `the ball bearing 41 are inserted pans 42 to accommodate felt `seals for the ball bearing,.and the lupper end .of the tube Y4t) is sealed by a plug 43 through y.the crown of rwhich the upper end of the spindle projects. kThe spool 44 is fitted over the tube 40, and bears 4at the bottom against Vthe edge of the collar 38.
The thread or filament to be :twisted is, in the manner already described, .guided `from lthe bobbin i4 through the bore 2 of the spindle lto thetpulley'S at the lower end of the spindle .and thence upwards to `the winding bobbin.
