andone of its objects is the PIOVlSiOQ at an-' tomatiomeans for indicating a defect or irregularity in the material to be wound. A further object of :he present invention is to provide means for stop'fiing a spool- Winrling machine when a defective portion of the materiai'tlo be. Wound appears or if such niaterial is broken while being wound.

Another object of the invention is the pr0- vision of automatic means for stopping a spook winding machine for insulated wire when such wire isinsnfiieient i yinsulated or hare at 'nnylportion thereof, and such portion reaches :1 predetermined point.

Another object Lo'provide auionintic means for stopping a spool winding machine when a part of the material about to be Wound is not of uniform diameter as when it is knotted, and such. part reaches a predoterinined point.

A further object of the invention is to provide improved and simplified means for guiding wire, thread or the like, and a recarding devlc'e to etiect a semi-automaticwindin Other GlJjCilS of my invention will ap-' pear hereinafter,-t.he novel comhinntions of watch closely xhe elements being pointed out in the claims.

Opposite the conductor 42 and also in engagement with the wire 12 ise lever 41 pivoted at 40. A spring 43 acts on tliecuter end of this lever tending to force the same against the conductor 42. If de sired, anti-friction rollers 44 and 44 may be mounted on the lever 41 and conductor 42, respectirely, in such positions that the wire 12 when passing between said lever and conductor will engage for the most part with the said rollers. gel 21 should he made of good conducting material and s that when a be. it portion of the insulated wire passes between said rollers, the fixed conductor and erer 41 will be electrically connected with each other. Preferably the Erection pulleys or rollers 7 and 8 are so located that a slight hendof the insulated wire tal place between the rollers'fll and t in laying the wire bare it the victim not suffi ient. from. the roller 8 the wire 12 extends amend the listed direction sheave-I15 and th' to the-"1 n- "lng arm 47 through an o .uning 5?. at the outer end of which it passes directly the $001 11. Above the pivotal point or the a. 47 the wire 12 passes ch ough a i way 53 formed by the semi- 1 -r u projections 52 and 52". To prevent the wire from leaving this guideway a cap 56 may be placed over the projections 52 and 52 as shown in Fig. 2. v

v The arm 4-? is pivoted at fiT li-ofliave a vertical movement, and the outer-end ofgthe arm is pressed into contact with the" layers on thespool 11 by the spring 48. The-outer end of the, arm may be lifted from the spool by means of the handle 45. The lever all 13 also mounted to have a horizontal movement which ineybe ell'ected by actuating thehandle'G. The arm 47 with its pivotal bearings 43 may be mounted onthe bracket 54, which in this instance, is shown fixed onthe bed plate B. y

. Pivoted at 63 to the lever of the handle {16 is a piston rod 62 which is also connected to the piston 64 moving in the cylinder 65 of a dash-pot. 'This dash-pot is preferably filled with fluid, as oil, and a bv-passGS pro vided for the passage ofrthe fluid from one side of piston tdth'oth er thigougli The conductor 42 and leso rollers 44 and 41', so,

outer end of the arm 47 is pressed against the wire on the spool 11. If the arm 47 were held stationary the wire would, of course, ride up on a previous spiral. By giving the arm i7 a certain retardation by means of the dashpot, the engagement of'the wire 12 with a previous spiral may bedepended upon to automatically move the arm 47 laterally and thus secure an automatic winding of the, wire 12 on the spool 11. For instance,'it the wire is being wound on the spool 11 as shown in Fig. the spool 11 is continually being brought into contact with the wire that has just been placed on the spool during the preceding rotation, so that the arm l? is forced to the left, the retardation due to the dashpot being adjusted to insure compact winding.

When the main line switch 96 is closed, a circuit may be traced from the main through wires 97, 98, and 58, switch 14, wire 59, foot switch 37, wire 60, brake magnet solenoid. 20, wires 61, 71, 102, and 103 to the main. The brake shoe 1' will thereupon be lifted from the brake pulley 151 andthe main line switch 22 closed. A circuit may now be traced from the positive main through the contacts 119, 118, wire 10?, to the brush 108 of the motor M, and thence through -the shuntwinding 111 of the motor and through the armature to the brush 110,

1, the wire 12 as it reaches v Wire 112, contacts 106, 105, wires 102 and 103 to the. negative main. The motor will now start to operate the winding mechanism. For the sake of simplicity I have shown no refinement of motor-controlling apparatus '1 other than the brake apparatus 16 andthe 'main line switch 22 for controlling the ormechanism connected thereto. 7
