(ci. s'z-ss) Claims. l

This invention relates to an improved mounting for textile mill spindles and particularly to a simple and efficient mechanism for mounting a, spindle assembly on a spinning or twisting machine frame or spindle rail thereof in such manner that the spindle assembly may be moved from its normal band-driven position to a nondriven position with respect to the driving band, thus indicating the general object.

Usually those types of spinning or twisting spindles which are adapted to be movably carried on the associated machine frames are provided with pivoted mountings enabling the supported spindles to be moved into and out of driving contact with the band. Those are quite bulky, are costly to manufacture and are subject to twisting forces causing wear on the mounting supports and eventually causing the spindles to operate out of plumb and -become unsteady. Furthermore, the pivoted mountings sometimes interfered with the separators or guards customarily placed around the spindle or between adjacent spindles to prevent fouling of the strand being wound on or olf the bobbins. A sliding support for a spindle has been heretofore proposed but no such arrangement has come into general use.

The present spindle mounting (indicating a further object hereof) can be made light in weight and inexpensively, has provision for accurately adjusting the spindle into vertical position and holding it there and continues securely to support the spindle for extremely long periods of time while enabling quick and easy movement thereof from driven to non-driven position and viceversa. The mounting can also be operated to retain the spindle indefinitely in its idle or nondriven position. The spindle is subject to easy release from the latter position and is automatically returned to driven position consequent upon a simple releasing operation by the attendant.

Other objects and features of the invention will become apparent from the following description of the preferred forms shown in the accompanying drawings, wherein:

Fig. 1 is an assembly view in the nature of a central vertical longitudinal section, showing the mounting mechanism and a spindle thereon;

Fig. 2 is a detail transverse sectional View of part of the spindle mounting slide and guide bar therefor;

Fig. 3 is a sectional plan view as indicated on assixnora' to The Mar- Company, Cleveland,

Fig. 4 is a fragmentary side elevation of the mounting mechanism and spindle;

Fig. 5` is a fragmentary view similar to Fig. 1, showing a modified mechanism for moving the spindle into non-driven position and releasably retaining it there; and

Fig. 6 is a plan view of the modified form.`

Fig. 1 shows the spindle assembly `A in driven position with respect to the driving band B, and Figs. 3 and 4 show the spindle assembly in nondriven position. v

In most spinning and twisting., machines, a mounting rail for each row of spindles extends parallel to the common or principal vertical planev of the spindles and parallel to the longitudinalY y axis of the driving band as guided for frictional engagement with the spindles of that row. As shown herein, the spindle rail or rail assembly R is in the form of a pair of vertically aligned substantially rigid tubes or pipes I 4and 2, suitably rigidly mounted on the machine frame by means not shown hereby.

The present arrangement, as one novel feature thereof, takes advantage of the spaced apart parallel relationship of rail forming pipes or tubes, such as shown, in so mounting the spindles that they can readily be brought into absolutely plumb or truly vertical position, notwithstanding expected inaccuracies in mounting the pipes or tubes I and 2 on the machine frame. The mounting would be appropriately modified for adaptation to other types of spindle rail or rail assembly.

The present spindle mounting comprises, as shown, a generally L-shaped yand substantially rigid mounting bracket generally indicated at 5 and which may comprise a main horizontal bar 6 and a carrier or bracket member or portion 1 therefor. The -bracket member is of inverted L-shaped, as shown, having a horizontal arm portion 8 secured as by welding or brazing at 9 and I 0 to the underside of the main supporting bar and a vertical arm portion IIJresting against respective rearwardly facing curved surfaces of the two tubes as shown in Figs. 1 and 4. Preferably said vertical-arm portion II has integral therewith a frusto-conical portion I2 which is wedged into engagement with both tubes I and 2 by a single attaching bolt I3. A rigid attaching l. pad or plate Il on the opposite side of ther-ail'v tubes has a similar wedging frusto-conicalporj tion I 5 and the attaching bolt I3 passes tllrughgV and the arm portion] Iff' coaxially of both frusto-conical portic'ins4 I2" and openings in the pad I4 I 5 so that pressure of the bolt head I6 and nut I1 will be adequate to clamp the entire bracket assembly tightly onto the tubes. Additionally, in order to make certain that the top surface of the main supporting bar 6 is level both longitudinally of the rail assembly and transversely of the rail assembly (for plumbing the spindle), a pair of adjusting screws I8 are threaded into the supporting bar 6 in vertical alignment with the upper tube I for bearing thereon as illustrated. The screws can beindividually adjusted from above the mounting bracket assembly in making certain that the main supporting bar 6 extends horizontally from the machine on which the spindles are to be mounted and that the bar is level in other respects.

The sliding support for the spindle is shown in the form of a sheet metal body 20 which may be generally C-shaped in cross section (see` Fig. 2),for slidably fitting the outer or free end portion 2l of the main supporting bar 6. The entire supporting bar is preferably rectangular in cross section, wherefore the inner defining walls of the slide 20 are also rectangular in form. The slide may have downwardly extending side walls 22 for its full length slidably fitting the narrow vertical edges of the bar 6 and inwardly turned flanges 23 slidably tting respective lower marginal surfaces of said bar. The top panel or spindle-supporting pad portion of therrslide is indicated at 25. y

The spindle-supporting slide 20 extends outwardly beyond the bar portion 2| away from the associated machine. The bar has a straight end face 24 as shown in Fig. 3. Any suitable provision may be provided for lubricating the slide, and further to decrease friction, certain of the adjacent surfaces of the slide and bar 6 may be `relieved as much as necessary as commonly practiced in machine design.

Between the ends of the top panel or spindle mounting pad portion 25 of the slide, the slide has an opening 26 for receiving the lower end portion of the bolster case 21 of the spindle A. If the spindle is to be tiltably mounted, thebolster case does not t the opening 26. Thus the entire spindle assembly may be tilted on the sup- 'porting slide during manipulation of the bobbin carried on the spindle. The bolster case has a rigid mounting flange 28, the bottom side of which rests on the pad portion 25 of the slide. In case it is desired that the spindle be tiltably mounted, the attaching nut 30 of the bolster case supports the lower end of a relatively stiff coil spring 3| and the upper end of the spring extends freely through an enlarged and preferably elongated opening 32 in the supporting bar 6 into firm contact with the lower surface of the slide. The opening 32 enables longitudinal movement of the slide along the bar 6 the desired distance. The nut 30 may be provided with a lock nut 33. The live part of the spindle comprising a blade 35 andwhorl 36 rigid therewith is carried in suitable bearings of the bolster case arranged for example according" to Herbert Gleitz Patent 2,351,951, issued June 20, 1944, owned by the assignee hereof. A whorl hook 31 on the flange 28 is shown overhanging the lower outstanding flange portion 38 of the whorl.

The slide 20 'is normally held inthe position thereof shown in Fig. i by a coiled tension spring 46 which ma be connected at one end to an upstanding ape tured ear 4i centrally on the top panel 25 of the slide and at the opposite end to an adjustable securing pin 42. The pin 42 is preferably carried on an upwardly turned bracket portion 43 of the bar. 6 and, as shown, is in the form of a screw. the threaded portion 44 of which extends through a horizontal opening in the upwardly turned portion 43 and is provided with a spring tension adjusting nut 45. The pin can be threaded to the opening in the bracket 43 or may extend loosely therethrough since the spring holds the screw from turning out of adjusted position.

Referring to the form of operating means for the slide 20 (left, Figs. 1 and 3), the top panel portion 25 of the slide 26 carries substantially centrally of the slide a cam 46 having an operating handle 41 shown in broken lines in Fig. 3 in its normal position in which the handle abuts a shoulder. on one flange portion 22 of the slide. In that position, the slide is moved to the right by the spring 40 until a fiat surface portion 49 of the cam abuts the flat end surface 24 of the bar member 6 of the mounting. The cam has an eccentric surface 50 which operates against said supporting bar surface 2'4 to move the slide to the left into the position shown by Figs. 3 and 4, carrying the spindle whorl away from the driving band B, thus enabling the spindle blade assembly to stop turning or be stopped by a suitable brake or otherwise. The cam has an additional flat end surface 5I which upon full face engagement with the bar surface 24 retains the spindle through the slide in its non-driven position. Io release the spindle supporting slide, the attendant gives the operating handle a slight motion in a counter-clockwise direction and the spring 40 then automatically returns the spindle to driven position with respect to the driving band.

In'the modified form shown by Figs. 5 and 6, the operating handle 41a is carried on the main supporting bar 6 as on a pivot pin 53 entering beneath said bar and the shifting of the slide 28 to the left is accomplished through an overcenter toggle mechanism including a link 54 pivotally connected as at 55'to the operating handle 41a between the'pivot 53 and the free end of the handle, and pivotally connected as at 5'6 to the slide. The handle 41a thus constitutes one arm element of the toggle. The normal position of the handle 41a in which the slide 20a is moved to the right from the position of the slide shown in Figs. 5 and 6, is indicated in broken lines, and the position of the handle in which the toggle is moved past dead center so as to be retained by the force of the spring 40 against a suitable limiting abutment 51 is shown in full lines. The abutment 51 depends from the slide 20a into the path of movement of the handle 41a. It will be obvious that a slight clockwise movement of the operating handle out of the full line illustrated over-center position of the toggle will enable the spring 40 to reverse the toggle mechanism and return the spindle whorl to driven position against the driving band.
