Other objects andadvantages will; be apparent; from the following detailed description when considered in conjunction with the accompanying drawings, wherein Fig. 1 is a schematic side elevational view of a wire enamelling machine embodying the control mechanism;

Fig. 2 is an enlarged side elevational view of the control mechanism shown in solid lines in its normal position and in dotted lines in its actuated position; and

Fig. 3 is an elevational view of the structure shown in Fig. 2, and taken substantially along the line 3-3 of Fig. 2.

Referring now to ,the drawings, attention; ;is first directed to Fig. 1 which illustrates a,wire=:.

enamelling machine indicated generally at,v HI which receives strands. or, wiresll from-supply reels,;l2, passing around sheaves l4 and, Hand The. j

mounted, on the shaft, :32, includes. a ,-plunger. 4 I;

normally spaced from the comb 33 but: positioned to be actuated thereby when the comb is moved out of its normal position. The arm 39 with the support 40 and the switch 38 are normally held in the positions shown in solid lines and against an adjustable stop 43 by a spring 44, the spring permitting movement of its associated structure into the broken line position when it is not possible for the comb to separate the adhering strands or wires.

The switch 38 is of the normally open type closed by the actuation of the plunger 4| to complete a circuit for an audible signal 46 mounted "fingers; 34' :.of::the -:comb1:will",extend between the normal paths, oft-the wires-ml l. .ito:maintainerthezv: wires inrtheir:eircnerpathsandirtotztendtorsep ratethemrshquld; theyiadhere-otq eachgotherc; A spring pressed plungcrtt. carriedby-the arm::3 I;

The circuit for the signal 46 may be traced from line 50 through the switch 38, the audible signal 46 to line l5.

Considering now the operation of the machine I!) with the control mechanism embodied therein, it will be apparent that during the normal operation of the machine, the strands or wires l I may be advanced continuously from their supply reels I2, through the applicators l6, and wiping dies I1 and the baking chamber 18. The applicator, wiping and baking steps are repeated, after which the wires are advanced through the capstan unit 22 and the distributors to their takeup reels 25. During this travel of the numerous wires, they may adhere to each other and in most instances, the fingers 34 of the comb 33 would be effective in separating the wires. However, if any two or more of the wires should be so firmly connected that the comb could not separate them, these wires in their vertical travel from the chamber l8 will engage the fingers 34'and thus move the comb 33 about its pivot or shaft 32. This movement of the comb will first cause operation of the switch 38 through the engagement of the plunger 4|, operating the signal 46 to indicate to the operator the condition existing whereby the operator may manually separate the wires before they repeat their travel through the machine I!) and cause disturbance in the attempt to advance these wires through their applicators I6 and dies 11. The spring 43 will allow the comb and switch supporting mechanism to be moved out of the path of the connected portions of the wires and as soon as this portion moves beyond the comb, the spring 43 will return the control mechanism to its normal position again positioning the fingers 34 between their respective wires.

It is to be understood that the above described arrangements are simply illustrative of the application of the principles of the invention. Nu-

merous other arrangements may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof.

What is claimed is:

1. In a machine wherein strands normally move in closely spaced parallel paths and adjacent strands may adhere to each other, a comb normally positioned with its teeth extending between the paths of the strands for separating the strands, an energizable signal, a pivot spaced from the paths of the strands to support the comb for movement out'of its normal position beyond the said paths by inseparable strands whereby the inseparable strands may travel beyond the comb without being broken thereby, and means operable by movement of the comb out of its normal position to energize the signal.

2. In a machine wherein strands normally move in closely spaced parallel paths and adjacent strands may adhere to each other, a control mechanism including a comb normally positioned with its teeth extending between the paths of the strands for separating the strands, an energizable signal, a pivot spaced from the paths of the strands to support the comb for movement out of its normal position beyond the said paths by inseparable strands whereby the inseparable strands may travel beyond the comb without being broken thereby, and a switch operable by movement of the comb out of its normal position to energize the signal.

3. In a machine wherein strands normally move in closely spaced parallel paths and adjacent strands may adhere to each other, a control mechanism including a comb normally positioned with its teeth extending between the paths of the strands for separating the strands, an energizable signal, a pivot spaced from the paths of the strands to support the comb for movement out of its normal position beyond the said paths by inseparable strands whereby the inseparable strands may travel beyond the comb without being broken thereby, a switch operable by movement of the comb out of its normal position to energize the signal, a movable support for the switch, and variable means to normally locate the support with the switch a selected variable distance from the comb.

4. In a machine wherein strands normally move in closely spaced parallel paths and adjacent strands may adhere to each other, a control mechanism including a comb normally positioned with its teeth extending between the paths of the strands for separating the strands, an energizable signal, a pivot spaced from the paths of the strands to support the comb for movement out of its normal position beyond the said paths by inseparable strands whereby the inseparable strands may travel beyond the comb without being broken thereby, a switch operable by movement of the comb out of its normal position to energize the signal, a movable support for the switch, variable means to normally locate the support with the switch a selected variable distance from the comb, and yielding means normally holding the switch support and the switch relative to the comb and to return the support with the switch and the comb to their normal positions.
