WINDING DEVICE Filed Aug. 1, 1940 Patented Apr. 29, 1941 1 mam o e a! Raymond L. Strube, Kinsley lians assignor to A. B. OhanceCompany, Centralia, Mo.,,a.corporation of. Missouri 1 Application Augustl, 1940, Serial No. 349,176 ..'z'o1 aims.. (o1.'57--10) This invention relates'to devices for-use by wire to high voltage electric transmission lines.-

The primary object of the present invention .is to provide a toolwhich will facilitate the wrap-- ping of aluminum armor ribbon around electric current transmission lines whereby the application of such armor to the line may be efiected in a great deal less time than is required at the present time by the employment of present methods. I

Another object of the'inve'ntion is to provide an aluminum ribbon wrapping or winding tool which is adapted to be employed in association with a hot stick such as is commonly employed by.electric linemen" working on high ten sion wires, whereby the lineman is able to applythe ribbon to the wire quickly and properly with out danger. c The invention will be best understood; from a consideration of the following-detailed: description taken in connection with the'accom'panying drawing forming part of this specificatiom with the understanding, however, that the'invention is not to be confined to any strict conformity with the showing of the drawing but may be cha'nged or modified so long assuch changes or modification mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawing: I, j v Fig. 1 is a view in elevation of the tool embodying the present invention. J

Fig. 2 is a view in top plan of the tool showing the same in operation.

Fig. 3 is a rear view of the working the tubular portion of the tool.

Fig. 4 is a sectional view taken substantially on the line 4-4 of Fig. 2;

Referring now more particularly'to the draw- 1 ing, the numeral I designates a portion of a, current conducting line or cable -whichfisto be wrapped with the usual aluminumfribbodhere indicated by the numeral 2, whereby to provide a protecting 'or covering armor overt'he cable adjacent to a supporting insulator, to facilitate the tying of the wire to the insulator in the customary manner. This armor ribbon is applied spirally to the wire so as to form thereabout a smooth protecting "sheath", as indicated at 3 in Fi 2. 1

The tool or implement embodying the present invention and by means of which the armor ribindicated generally by the numeral 6, which may be rotated axially on the wire and moved long'itudinally thereof.

"ne of the bodies of the sleeve, here showrras the body}, is secured to an end of an elon'gated plate or bracket 1 which extends transversely'i'of the sleeve and which at its opposite "end is=a ngularly or laterally turned to form the flange 8 which extends across the other portion. of the sleeve which is movable relative to that portion which is attached to the bracket plate. This flange 8 carries a nut 9 which is alined with an aperture not shown, of the flange," and through this nut extends the threaded bolt or screw I0 which has its inner end swivelly coupled, as at H, to the portion of the tubular sleeve or guide which is free 'of the bracket, such portionbeing here designated by the numeral 5.

Theouter end of the screw I0 is formed to pro vide-the eye I2 which facilitates theattach'ment to the device of the hook of a hotstick such as is commonly used in Working upon high tension transmission lines. i

The bracket 1 is relatively narrow and in View of this and in order to stabilize the structure, there is provided a brace arm l3which isat taohed atone end to the end of the bracket adjacentthe flange8 while at its other end? it extends across the movable portion '5 of the sleeve adjacent an end of the latter, and is attached to the adjacent end of the fixed portion 4 of the sleeve.

' The end of the movable portion 5 of the sleeve remote" from the arm I3, is cut obliquelyto the length of the sleeve, as indicated at 15. The end of'the fixed portion 4 adjacent .to the obliquely cut end l5 of the movable portion is cut transversely through approximately half of its width" as indicated at l6, fro-m that side which is nearest the point I! of the obliquely cut end of the portion 5 and is then provided with the longitudinally extending edge l8 which is slight 1y oblique to the center of the sleeve, as shown in Fig. 2. There is thus formedin the end of the fixed portion kof the sleeve, a notch orrecess through which extends the. tape"'or ribbon 2 whichisbeing wound on the cable. 'I'he edge l8 functions asla guide for the ribbon a'sthe tool'is rotated around the wire or cable], the slightly oblique longitudinal edge of the notch in the portion 4 functioning to keep the ribbon in the inner end of the notch and the oblidue end edge- |5 of the movable portion 5 which extends transversely with respect to the line of the {portion of the ribbon entering the notchjserves as an abutment for the last turn or spiral of the ribbon coil; 5 5

Fromtheforegoing, it "will be readilyappareni? that the device embodying the present invention is so constructed that it may be applied to a hot wire by means of the usual hot stick" and it may also be rotated on the wire by the attached hot stick so that the lineman will not be required to touch the tool or the wire in winding the ribbon about the wire.

The inner surfaces of the two portions 4 and 5 of the sleeve are preferably provided at the ends thereof with short linings of a soft bearing metal, as indicated at l9. These lining inserts for the sleeve portions coact to form bearing guides so that the major portion of the wire I is free of contact with the sleeve and, therefore, the sleeve may be easily or smoothly turned on the wire.

The flange 8 is provided upon opposite sides of the nut 9 with the downwardly extending lugs l9. These lugs parallel the screw it) and are spaced from the nut as shown in Fig. 1.

As previously stated, the device is constructed to be applied to a wire and handled by the usual or conventional type of hot stick which is employed by linemen when working on high tension wires for the handling of devices which are electrically connected with the wire.

In starting a, ribbon such as is indicated at 2 upon the wire, the lineman takes the roll of ribbon and forms an open eye in one end thereof. This eye is then placed over the high tension line by the aid of a pair .of hot wire tongs which are suitably insulated to facilitate handling the ribbon without requiring the lineman to touch the same or the wire. The eye of the ribbon is secured over the wire by the tongs and the winding device which may have been previously applied to the wire by means of the hot stick is slipped down the wire and the ribbon is fitted in the end of the winder against the bearing edge l8 thereof. The portions 4 and 5 of the device are then tightened up so as to firmly enclose the wire and turn thereon but hold the ribbon firmly so as to effect the spiral winding of the ribbon in the manner illustrated. The winding device is then rotated around the wire and after the ribbon has been wound onto the desired extent, the eyed end portion of the ribbon is cut or broken oif, so that the end of the ribbon will lie tight against the wire.

The conventional type of hot stick which is employed for taking a hold on the screw eye 12 is of standard and well-known construction, therefore, it is not believed that any detailed explanation of the character of the hot stick securing or clamping head is necessary. This head is provided with a recess into which the eye I2 is received and the lugs l9 also engage in the opposite sides of the recess so that the hot stick will be held in connection with the screw [-0 against turning.
