AUTOMATIC STOP GAUGE FOR WINDING MACHINES Filed Feb. 2, 1949 INVENTOR.

Patented Oct. 30, 1951 AUTOMATIC STOP GAUGE FOR WINDING MACHINES Charles W. Guion, Arlington, Va.

Application February 2, 1949, Serial No. 74,167

Claims. (01. 24239) (Granted under the act of March 3, 1883, as amended April 30, 1928; 370 0. G. 757) The invention described herein, if patented, may be manufactured and used by or for the Government for governmental purposes, without the payment to me of any royalty thereon.

This invention relates to automatic stop motions for winding machines and has for its primary object to generally improve devices of this type.

More specifically, it is an object of the present invention to provide an electrically-operated stop gauge mechanism which will serve to stop the winding of a spool or cop when the desired amount of thread has been wound thereon.

A further object of the invention resides in the provision of such a stop mechanism which may be readily adjusted to vary the stopping of the spool or cop in accordance with a predetermined amount of thread that it is desired to wind.

It is a still further object of the invention to provide a series or gang of stop mechanisms all of which may be simultaneously adjusted at a single operation.

Another object of the invention resides in the provision of an electrically-operated stop mechanism which may be readily installed on winding machines of the type shown in J. O. McKean Patent No. 1,958,060, in which the spools are automatically stopped if the thread breaks or becomes exhausted.

Another object of the invention consists in providing an electrically-operated stop mechanism in which the electric circuit is automatically opened immediately after the stop mechanism has been activated.

Other objects and advantages of the invention will be apparent from the following description when taken in connection with the accompanying drawings, in which Figure 1 is a vertical transverse sectional view of the winding machine of Patent No. 1,958,060, showing the improved stop mechanism installed thereon. v

Figure 2 is an enlarged front elevational view, partly broken away, of a battery or gang of micro-switches and showing the structure by which they may be simultaneously adjusted to determine the size of the packages to be wound, and

Figure 3 is a fragmentary front elevational view of the machine with parts omitted for the sake of clearness.

The automatic electric stop gauge forming the subject matter of the present invention is primarily intended for installation on winding machines of the type shown in the McKean patent referred to above, and inasmuch as this mechanism is clearly shown in that patent and is a well-knowncommercial item, it is deemed necessary to show in the present illustration only such features of the winding machine as cooperate directly with the attachment. This stop mechanism for gauging the size of the wound cones may with slight modifications in structural details be employed on other types of winding mechanisms.

The numeral I indicates the upper portion of the frame of the mechanism, while the numeral 2 represents a series of cones to be simultaneously wound, and the numeral 3' indicates winding rolls operated by motive power from any suitable source and adapted to engage and rotate the cones 2. In the winding machine of the present illustration, the cones or spools are mounted on spool holders which are carried by pivoted arms 4, and which arms are controlled by the mechanism indicated generally by the numeral 5 to raise the spools or cones 2 from the winding rolls 3, when the thread breaks or is exhausted.

The particular mechanism for causing a discontinuance of the winding operation when the thread breaks or is exhausted comprises a detector wire 6, which is pivoted to the frame work of the machine, as indicated by numeral 1, and is normally held in the position shown in Figure 1 by the thread 8, which is being wound from the bobbin 9, onto the spool or cone 2. Associated with the pivot 1 is a tripping roller l0, adapted to cooperate with a kicker cam II, when the detector wire 6 is allowed to move upwardly about its pivot 1, by reason of the breaking or exhausting of the thread 8. This movement of the kicker cam will throw the roller l0 out of the path of the cam, and thereby operate the mechanism indicated generally by the numeral 5, to permit a spring l2 to raise the spool 2 out of contact with the winding roll 3, thereby discontinuing the winding operation. This mechanism is all shown and described in the McKean patent, as previously referred to. i

The attachment of the present invention comprises a series of electrical switches 20, which are mounted on arms 2|, which are in turn fixed to an oscillatable shaft 22, supported in hangers 23, secured to the under surface of the frame I. This shaft 22 is preferably provided with screw threads at each. end for cooperation with wing nuts 24, by means of which the McKean patent is operated whenthe detee-t'or: wire is allowed to rise by reason of the breaking or exhaustion of the thread 8, and the present improvement resides in providing additional means for raising the detector wire 6, when the spools are filled regardless of Whether the thread 8 is broken or exhausted. This mechanism comprises a solenoid 25 so positioned that its plung= er 26, when retracted will be in engagementwith the underside of the detector wire 6, when the latter is. held in its loweredi position by the'threa'd 8" being Wound upon the spools. Whenione: of the circuits in which the respective'solenoi'd's 25 and switches 26 are-mounted is closed, the; plunger 26 will raise the-particular detectonwire 6', thereby setting in operation the: mechanism heretofore described-by means of which-the 'lever i is caused to rise so as to disengage the particular s'pool 2 from. itsroller 3, thereby discontinuing the ro tation of the particular spool;

The switches 20 are so disposed with relation to the oscillat'able shaft 2 2 as to form an angle of about 26 with the'vertical in the presentillustration, and this angle will beinc'reased as the arms 21 and the switches Ell are adjusted sa es to stop the mechanism in the formation of larger packages. A particular advantage of thisco'nstructionis that the switches 20 are allowed to open just' as soon as the mechanism 5' has been set in operationto lift-thespools- 2E thereby p'reventingheating'of the coils.

By means ofthe construction described herein, it will be apparent -to -th'ose skilled inthe art that the stopmechanismmay be: readily adjusted to vary the size of a spool being woundi stop mechanism maybe--simultaneouslyadjusted for allof the spools by a' suitableadiustment-"of the shaft 22; and that-the switches are-mounted so -as-to-be automaticallyppened whentlie wind% ing operationi's discontinued and thereby prevent heating of the'solenoid coils;

In accordance with the patent statute's; Ihave described herein what I now' considen'to betlie preferred form-of the invention suitable'for in' stallation upon the'McKean winding machine; but it is'to be understood'thatthe mechanism may be modified as to various detailsforinstalla tion on other types of'winding machineswithout in any way departingfroin'thespirit' ofthe'in' vention, and it is intended that all such varia-- tions be included withinthe' scopeof th'eap'pend= ed claims.
