Original application filed March 25, 1919, Serial No. 285,000. kDivided and this application filed July 10,
1920. vSerial No. 395,298.
To all whom .it may concern:
Be it known that we, ROBERT'P. Asri- BAUGH and SAMUEL C. CAwTHoN, citizens of the United States, residing at River Forest, in the county of Cook and State of Illinois, and Cicero, in the county of Cook and State of Illinois, respectively, have inventedcertain new and useful Improvements in Winding Mechanism, of which the following is a full, clear, concise, and exact description.
This invention relates to winding mechanism, and more particularly to a winding head for applying insulating tape to conductors.
The object of this invention is to provide a simple and practical mechanism for applying a hemmed or lapped tape to a conductor in accordancewith the features of the invention as disclosed in'our co-pending application, Serial No. 285,000, filed March 25, 1919, of which this application is a division. Such a mechanism may comprise in general a winding head and a lplurality of tape guides, yone of which is provided with a curved slot therein by reason of which the paperpassing through it has one margin turned or lapped in. such a manner that its application to the conductor will form a spiral ridge whichpositively supports the rest ofthe tape out of contact with the conductor. -The guides for the tape are made adjustable so that the angle of application of the tape to the lconductor may be varied within reasonable limits.V A flexible cone guide and a polisher are also provided which serve to apply the tape to the conductor witlia uniform cylindrical surface. Y I
In the drawings illustrating this inven tion- Figure 1 is an enlarged View of an insulated conductor made in accordance with this invention and showing the insulating tape unwound for a short distance;
Fig. 2 is an enlargedlongitudinal sectional View illustrating the relation of the tape and conductor cov'red thereby;
Fig. 3 is an enlarged cross-sectional View taken upon line 3 3 of Fig. 1; v
Fig. 4 is 'a view'in front elevation ofa winding head by means of which the insulation is applied to the conductor in the form shown in Figs, 1, 2, and 3;
resents a conductor around which is spiraled an .insulating tape 6,y preferably of paper, having on the lower margin thereof a ridge 7 which is formed by hemming or 'lapping'v one margin of the tape before it is applied to the conductor. The tapecovering 6 is supported by the ridge '7 and forms a smooth cylindrical shell of uniform external di- 'ameter about the conductor 5 which is centered within the tape covering 6 by means of the ridge 7 and isv substantially parallel to the tape covering. By means of the ridge 7, which isforme'd by vhemming or lapping the margin of the tape, the body of the tape is positively maintained out of contact with the wire, due to the fact that with such 'a ridge the pressure upon conductors so insulated is unlikely to cause al collapse of the insulation against the conductor, 'and the air space thusprovided is maintained even under conditions 'of pressure which result from the twisting of the conductors into pairs and cables.' Y In-Fig.- 4, 10 designates' a Vwinding vhead which may be driven in any suitable manner and upon which is mounted a tape roll'1`1 in a manner to unwind in the direction' of rotation of the head. Secured to said vhead is an upright wire guide member 12 through which a wire 13 to beinsulated is drawn.
yturned over at onemargin thereof. As the tape leaves the guide member 17 it yis wrapped about the wire 13 and is drawn through a exible cone guide 20 andapolisher 2 1 which compress lthe tape 19 about the wire A the tape roll.
and `give to itA asmooth cylindrical surface.
Mounted nea/r the lower end of the wire guide member 12 isa second pivotal arm22 upon which is adjustably mounted a pivotal guide lever 23 which serves toA guide the tape from the supply roll 11 to the guide member 17 and to maintain the two edges thereof in parallelism and in the same plane. Secured to the lower base of the pivotal arm 22 is a spring member 25 which rests upon the top of the tape roll 1l and acts as a brake thereon to prevent overrunning of At its outer end the arm 22 is provided with a slot 26 through which Aextends a spring held catch member 27 supported in a post 28 secured to the head 10. The catch member 27 permits the release of the arm 22 so that it may be swung from a horizontal to a vertical position to permit a new tape roll to be supplied upon the head 10.
The flexible guide 20 and the polisher 21 are removably mounted in the end of a pivotal lever arm 30 which may be swung to one side to permit a new tape roll to slip 'over the guide 20, the polisher 21, the guide 17, the guide 14, the lever arm 22 and its associated parts, and into position upon the head l0 from which the tape may be fed onto the conductor.
The tape as it leaves the roll 11 is passed around a guide post 36 under the guide finger 23 and through the guide member 17 onto the wire.
The polisher 21 is held in position in the pivotal arm 3() by means of a clamping screw 38.
Ihat is claimed is: y jl. A combined forming and winding head for applying a lapped or hemmed paper tape to a conductor, comprising a rotating supporting table for the tape, a wire guide through vwhich the'wire to be vcovered is drawn, and a tape guide carried by said wire guide for lapping one margin of the tape beforethe tape is wound upon the conductor.
2. In a head for insulating conductors with tape, a tape supply roll, a rotatable support for said tape lsupply roll, a wire edge of said tape, and a conical guide mem-v ber and a polisher surrounding said wire above said guide for forming said tape into a tube around the wire.
4. In a winding head for insulating conductors with tape, a tape supply roll, ,a r0- tatable support therefor, awire guide carried by said support through which the wire to be covered is drawn, a tape guide having a J-shaped slot therein for turning over'one edge of the tape, and a flexible conical member and a polisher surrounding said wire above said guide for forming said turned-over tape into a smooth surfaced cylinder around said wire.
5. In a winding head for insulating conductors with tape, a tape supply roll, a rotatable support therefor, a wire guide cary ried by said support through which the wire to be covered is drawn, and a pair of adjustably mounted tape guides carried by y said wire guide, lone of said guides being provided with means for lapping or hemming on'e margin of the tape.
6. In a Winding head for insulating conductors with tape, a tape supply roll, a rotatable support therefor, a wire guide carried by said support through which the wire to be covered is drawn, an adjustable guide carried by said wire guide at one end thereof and having a curved slot therein for lapping one edge of said tape as it passes therethrough, and a second adjustable guide located at the opposite end of said wire guide for leading the tape to the slot in the slotted guide.
In witness whereof, we hereunto subscribe our names this 23 day of June, A. D. 1920.
