3 Claims. (Cl. 57-77.45)
This invention relates to twisting means for textile machines, and more particularly to an improved twisting means arrangement by which the twisting direction can be changed readily in a variety of ways to provide for twisting diierent yarn ends, or successive lengths of each yarn end, oppositely on the same machine, or to allow twisting of all yarn ends on a machine in either direction.
Briey described, the twisting means of the present invention is characterized by a unit comprising a pair of spindle tubes fitted with false twisting elements, a bracket structure rotatably carrying the spindle tubes in spaced parallel relation, and means for connecting the spindle tubes as carried on the bracket structure so that either spindle tube may be caused to rotate in the direction opposite to the rotating direction in which the other is driven, together with means for selectively driving either of the spindle tubes, all as described in further detail below in connection with the accompanying drawings, in which:
Fig. 1 is a fragmentary elevation detail of a twisting means unit arranged in accordance with the present invention;
Fig. 2 is a top plan detail corresponding generally to Fig. 1;
Fig. 3 is a sectional detail taken substantially on the line 3-3 in Fig. 2; and
Fig. 4 is a plan detail of the spindle tube supporting bracket employed in the twisting means unit illustrated in Figs. 1, 2 and 3.
Referring now in detail to the drawings, the reference numeral designates generally the spindle tubes that that are prov-ided in the twisting means unit illustrated, a pair of these spindle tubes 10 being carried for rotation in spaced parallel relation by a bracket structure 12, which is in turn pivotally mounted on a pivot post 14 in symmetrical and axially parallel relation with respect to the pair of spindle tubes 10.
Each spindle tube 10 is fitted with upper and lower bearing units 16 and 18 (see Fig. 3) at which it is clamped in place on upper and lower arm portions 20 and 22 of the bracket structure 12 by cap members 24 and 26 in essentially the same manner as is disclosed in copending application Serial No. 675,122, tiled July 30, 1957. Each spindle tube 10 is further litted at its upper end with a false twisting element 28 arranged to have a yarn end Y wrapped thereon and trained through the spindle tube 10 as indicated in Fig. 3. In addition, the bracket structure arm portions 20 and 22 are spaced so as to present an intermediate portion 30 of each spindle tube 10 for contact with a driving belt B, and these intermediate spindle tube portions 30 are preferably of enlarged diameter for effective driving contact with the belt B, this enlarged diameter being readily accommodated by the above noted mounting arrangement on the bracket structure 12 without requiring any complication in structure or installation of the spindle tubes 10.
A pair of mating gears 32 are also respectively carried.
by the pair of spindle tubes 10, according to the present invention, for engagement to cause rotation of eitherl of the spindle tubes 10 in the direction opposite to the direction in which the other is rotated, and means is provided for selectively pivoting the bracket structure 12 about pivot post 14in either direction from a neutral position with respect to driving belt B (see Fig. 2) to a position at which the driving belt B is applied to only one of the spindle tubes 10 for rotating it.
The means provided for this latter purpose comprises a traverse bar 34 arranged to extend lengthwise ofthe machine past a spaced series of the above ydescribed twisting means units supported in properly spaced relation by mounting brackets 36 on which the pivot posts 14 are ixed. The bracket structure 12 carrying the spindle tubes 10 at arm portions 20 and 22 has a further oppositely extending arm portion 38 at which a pivot stud 40 is carried to dispose a collar block 42 thereon with the traverse bar 34 running therethrough. The traverse bar 34 is in turn iitted with pairs of collars 44 iixed thereon in spaced relation to maintain springs 46 bearing oppositely on washer elements 48 at each side of each collar block 42.
By this arrangement, the positioning of the twisting means units is made responsive to reoiprocation of the traverse bar 34 which may be readily arranged through suitable cam or gear connections (not shown) at one end of the machine, or elsewhere, to reciprocate in accordance with any selective positioning of the twisting means units desired.
As seen in Fig. 2, reciprocating movement of traverse bar 34 to the right would result in applying the driving belt B selectively to the right hand spindle tube 10 for rotating it in one direction and causing reverse rotation of the left hand spindle tube 10 through mating gears 32. If this positioning, or the reverse, were maintained, each twisting means unit would operate to produce righthand twist at one spindle tube 10 and left-hand twist at the other.
Alternatively, the traverse rod 34 might be actuated to reciprocate periodically so as to reverse the positioning of the bracket structures 12 at intervals and thereby reverse the tW-ist produced by each spindle tube 10 at successive lengths of a yarn end Y passed therethrough; right hand twist being produced by one spindle tube 10 of each pair and left hand twist by the other at one pivoted position of the bracket structures 12, a zone of no twist resulting as the spindle tubes 10 pass through the neutral position shown in Fig. 2 in the course of pivoting the bracket structures 12 to their oppositely pivoted position, and the twist produced by each spindle tube 10 being reversed upon reaching this oppositely pivoted bracket structure position.
In addition, the bracket structures 12 may set in the neutral Fig. 2 position and one of the mating gears 32 removed from each twisting means unit to allow rotation of all of the spindle tubes 10 from the driving belt B and thereby produce the same direction of twist at each spindle tube lll whenever desired.
The present invention has been described in detail above for purposes of illustration only and is not intended to be limited by this description or otherwise except as defined in the appended claims.

Twisting means of the character described comprising a pair of spindle tubes tted with false twisting elements, a bracket structure rotatably carrying said spindle tubes in spaced parallel relation, means connecting said spindle tubes as carried on said bracket structure for causing either of said spindle tubes to rotate in the direction opposite to the rotating direction in which the other is driven, and means forI selectively driving either of said spindle tubes.-
