8 Claims.

This invention relates generally to tie sticks adapted for use in applying and removing tie wires which secure energized electrical cnductors to insulators,

and more specifically to an provided with eyes heretofore necessary when tie sticks of the prong type were employed.

As is generally known to persons familiar with such matters, tie wires which serve to secure electric line conductors to insulators on poles and other elevated places heretofore were provided with eyes or loops at their ends, so that the tie wires mi ht be engaged by tie sticks of the prong type when the tie Wires were being applied or removed. The head of the improved tie stick dis closed herein is of the blade type, and is soconstructed that tie wires manipulated thereby need not be provided eyes or loops.

improved head is notches which are Briefly stated, the

provided with a plurality of adapted to engage a tie wire when same is being applied to or removed from an energized line, and because of the arrangement of these notches a number of different grips for engaging the tie wire from diiferent angles either for pulling or pushing movement are provided.

In the drawing,

wherein are shown for the purpose of illustration, merely, two embodiments of the invention, A designates in Fig. 1 an insulator, B designates an electric line conductor, and C designates a tie wire which serves to secure the conductor to the insulator.

The improved tie stick includes a handle in the form of a wood pole l having associated therewith at an end thereof a head 2.

As shown in Figs. 1, 2, and 3,

'lator.

the pole l is provided at the end thereof at which the head 2 is located with an elongated sleeve 3, into which, the pole l is extended a considerable distance, as shown mostclearly in Fig. 2, and this sleeve is secured to the pole by pins 4 which extend through oppositely disposed apertures formed through the wall of the sleeve and pass transversely through the pole. The. sleeve 3 is formedof bakelite or some other suitable electrical insulating material, and said sleeve extends outwardly. beyond the end of. the pole which is located within the sleeve. Located within the portion of the sleeve. which is. extended beyond the end of the. pole is a plug 5 of bakelite or other suitable electrical insulating material, which is provided witha screw-threaded aperture iiformed therein, said plug being secured in place by a pin 5' which passes through apertures formed through the wall of the sleeve and extends transversely through the plug.

The head. 2 includes a blade portion 1 and'a shank portion 8, said shank portion having a screw-threaded portion which is screwed into the screw-threaded aperture 6 formed in the plug 5'. The screw-threaded shank portion is rigidly fixed to the plug 5 by a pin 9 which extends transversely through said plug and through said shank portion, and the blade portion I of the head is preferably inclined slightly relative to the maior axis'of the shank portion 8, as shown most clearly in Fig. 2. The blade portion of the head 2 of the improved tie stick is provided at. each side thereof with a pair of notches I0, which open toward each other, and each of said notches is provided with an inclined wall l0 which renders the notch more or less wedge-shaped. The opposite side. portions of the blade portion of the head are provided with openings H, which serve as entries to the notches. Also, at its outer end the blade portion of the head is provided with a 40 v-shaped notch l2. v

In using the improved tie stick for tying in an energized line, the tie wire is first assembled at the top of the insulator, allowing the long, loose ends for wrapping at opposite sides of theinsu- The insulator is then screwed onto its pin with the wire groove A in position to receive the line conductor B. A long end of the tie wire is then gripped in one of the notches ll] of the head of the tie stick, and said long end of the tie wire is pushed over the'top of the conductor. The blade of the head is then disengaged from the tie wire, and said tie wire is taken hold of by another notch of the tie stick head from beneath the line conductor and is pulled around a half turn toward the operator. The tie stick head is again disengaged from the tie wire, and said tie wire is engaged by a different notch which is so positioned that the tie wire may again be pushed over the top of the line conductor. These operations are continued until the entire lengths of the loose ends of the tie wire are spirally wrapped.

about the line conductor. a

When the improved tie stick is used for removing 01d tie wires an end of the tie wire is engaged by the notch [2 or by one, of the hook-shaped portions l3 of the head, and the end portion of the tie wire is pulled away from the line conductor.-

The tie wire is then pushed and pulled around the .line conductor with the aid of the tie stickin the manner already described, so as to unwrap the tie wire from the line conductor.

By providing the head of the tie stick with the plurality of notches shown in the drawing and de-. scribed herein, the tie wire may be gripped in different ways and from different angles, so as to conveniently perform the wrapping and unwrapping operations. Also, by providing the tie stick with the bakelite sleeve 3 which is located close to the head, the exposed metal parts of the tie stick are reduced to a minimum and protection is aiforded the wood handle which is subject to considerable abrasion caused by coming intocontact with the line conductors and tie wiresQ In the form of the invention shown in Figs. 5 and 6, the head 2 includes a screw-threaded portion 8' which extends into an opening l4 formed longitudinally through the pole I of the tie' stick. The head 2' is provided with an outwardly extended flange I5. which contactswith an end of a bakelite sleeve 3, said sleeve being secured to the pole l by a pin I6. 7 The end of the portion 1 of the pole l which is located Within the sleeve 3 is' spaced inwardly a slight distance from the outer end of the sleeve,.and a portion ll of the head 2' is located in this space. The pole I has a circular hole I8 formed transversely therethrough, and driven into this hole so that its position is fixed therein is an element l9'shaped as shown in Figs. 5. and 6. The element [9 has a screw-threaded opening formed therethrough which receives the screw-threaded portion of the shank 8 1 in assembling the form of the invention shown in Figs. 5 and 6, the shank portion8 of the head is introduced into theopening [4 formed longitudinally through the, 'pole I, and the screwthreaded portion of said shank is screwed through the screw-threaded opening formed through the element'l9. When the face ll of the head has been seated against the adjacent end of the pole, the pin I6 is passed through apertures formed through the wall of the sleeve, through the pole,

and through the shank portion of the head to securely fixsaidparts together.

By referring to Fig. 2, it will be noted that the pin 9 extends through the shank portion 8 of the head and through the plug 5, and that the opposite ends of this pin are covered by the insulating sleeve 3. 'Because of this arrangement, the pin may be formed of steel so as to provide durable means for securely, fixing the plug and the shank portion of the head together, and the sleeve shields the steel pin and prevents accidental flashover to the pin, thus insulating all parts of the structure with the exception of the head itself.
