6 Claims.

This invention relates to conductor holders and has relation more particularly to a holder of this kind for connecting a high voltage conductor to an insulator, and it is primarily an object of the invention to provide a holder of this kind which dispenses entirely with the necessity of using a tie Wire.

The invention also has for an object to provide I a device of this kind which will hold the conductor in the clear of the insulator so that the insulator groove does not have to line up with the conductor.

The invention also has for an object to provide a holder of this kind which does not appreciably reduce flash-over values and which eliminates all of the conductor wear as a result of bearing on the insulator.

A still further object of the invention is to provide a holder of this kind which minimizes possibility of conductor breakage due to vibration or whipping and wherein the holder is sufiiciently flexible and resilient to permit the holder to function similar to a dampener.

The invention also has for an object to provide a holder of this kind constructed and assembled in a manner whereby it will remain for a protracted period of time upon an insulator and more especially for a time considerably longer than a conventional tie wire now generally in use.

A further and particular object of the invention is to provide a holder of this kind which initially is completely assembled as a unit requiring no dismantling either in putting on or taking off the holder.

The invention also presents a holder constructed in a manner to engage or clamp a conductor in a way to minimize endwise slippage of a conductor in case of line breakage.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved conductor holder whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

v The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view in top plan of a conductor holder constructed in accordance with an embodiment of my invention and in applied position upon a conventional petticoat type of insulator, a portion of the insulator being broken away;

Figure 2 is a view in side elevation of the assembly as illustrated in Figure 1, the insulator being shown in fragment;

Figure 3 is a detailed sectional view taken substantially on the line 3-3 of Figure 1 with the insulator fragmentarily shown in elevation;

Figure 4 is a fragmentary view partly in elevation and partly in section illustrating an initial step employed in placing the holder upon an insulator; H Figure 5 is, also a fragmentary view partly in section and partly in elevation illustrating a means for separating the clamping jaws of the holder to receive a conductor therebetween;

Figure 6 is a fragmentary view partly in section and partly in elevation illustrating a holder constructed in accordance with another embodiment of my invention;

Figure '7 is a fragmentary view in top plan of the structure illustrated in Figure 6 with the associated insulator indicated by broken lines.

In the embodiment of the invention as partic ularly illustrated in Figures 1 to 5 inclusive, my improved holder comprises a pair of elongated bars I and I substantially straight from end to end. The bar I is slightly longer than the second bar I and the extremities of bar 5 are formed to provide clamping jaws 2 substantially V-shaped in cross section for coaction with the jaws 3 also substantially V-shaped in cross section carried by the bar I adjacent the ends thereof. The bar I also carries the additional jaws 4 substantially V-shaped in form and which are positioned inwardly of and spaced from the jaws 2. The jaw 3 is carried by, the bar I and is received between the jaw 2 and jaw 4 of the second bar I whereby the bars I and I are effectively maintained against undue relative endwise movement. The extremities of the bar I are provided with the outstanding diverging lugs 5 which coact with the jaws 2 of the bar I to provide a further means for holding the bars I and I a against relative endwise movement and which also serve to facilitate the placement of a conductor C between the several jaws 2, 3 and 4 for clamping engagement thereby.

The bars I and I immediately adjacent to the inner ends of the jaws 2 and 3, respectively, are provided with the depending webs 6 which have their side marginal portions defined by the outstanding flanges I and 'I'. The flanges are carried by each web 6 of the bar I and the flanges 'I' by each web ii of the bar I The flanges I are spaced apart a distance to snugly receive therebetween the nuts 8 three upon the elongated headed bolts 9. These bo ts 2- freely disposed through suitable o vided in the webs 5 and These 0 are of a diameter slightly in excess of eter of the bolts so t" t the webs 1'- have slight rock vement in a lengthwise of the bolts 53 or in a dlftiuli transversely of the bars 3 d i The heads ll of the bolts 9 are received between the flanges l and these flanges are spaced apart a distance sufficiently and so constructed and formed to permit a wrench head 22 to be received therebetween for proper engagement with the heads ii to either tighten or loosen the bars I and l, or more particularly the clamping jaws 2, 3 and 1 carried thereby. As is particularly illustrated in Figure 4 the wrench head i2 is of a socket type and has universal connection, as at M, with an insulated pole P so that it is possible for a lineman to effect a tightening or loosening of the bars i and I from positions below and to one side of the insulator or from other positions which may be found necessary for the lineman to occupy. These flanges l by their shape and arrangement also serve as guide elements to facilitate the proper centering of the wrench head !2 for engagement with a bolt head I i.

The inner flanges of the bar l and the inner flanges 'i" of the second bar have integrally formed with the lower portions thereof an interposed bar I5 so constructed and arranged to provide a central jaw ill to be received within a conventional side groove i'l provided in the top or outer portion of the insulator A. It is also to be noted that the bars l5 are so constructed and formed to provide for the requisite spacing of the jaws l 6. As is particularly illustrated in Figures 2 and 3 of the drawings, it is to be noted that the webs 6 are of such length as to clear the bars I and and the jaws carried thereby from the outer or upper end of the insulator A so that in applying my improved holder it is not required to have the groove !8 in the top of the insulator line up with the conductor C.

In view of the foregoing description it is believed to be obvious ts .-t the holder comprises two separate sections which are held together by the bolts Q so that when the holder is received by the lineman for placement the holder is a completely assembled unit requiring no dismantling in putting the holder on the insulator. At this time it is also to be stated that no dismantling ill be required in taking the holder ofi of the insulator.

In applying the holder H to an insulator the bolts 9 are so adjusted as to assure a sufficient initial separation of the bars l and i and the jaws iii to assure a proper placing of such jaws within the groove ii. The pole P hereinbefore referred to carries an adjustable work engaging member or hook it which is engaged with one or the jaws 55 as illustrated in Figure 4. With the holder hanging down from the m mber S9 of the pole P such pole is manipulated by the lineman until a second jaw iii of the holder is engaged within the groove ll of he insulator. The hook or member iii can then be manipulated to cause the jaw with which it is engaged to drop down upon the insulator A in position to also be received within the groove i'l. During this latter operation the member or hook it is freed from the holder which can be readily done by turning the pole P to bring the member or hook I9 into substantially a horizontal position.

After the holder H has thus been initially and loosely applied to the insulator the lineman causes the member or hook Hi to be engaged under one of the bars, as l as illustrated in Figure 5, so that upon proper manipulation of the pole P said bars I and I together with the jaws 2, 3 and 4 carried thereby will be separated to permit the reception of the conductor 0 therebetween. After this operation the wrench head 12 is engaged with the heads ll of the bolts t to draw the bars l and l one toward the other to effect desired clamping action upon the conductor C and also to cause the jaws 15 to have desired tight engagement within the groove l! with the insulator A. Effective clamping engagement with both the conductor C and with the insulator is assured due to the rocking movement permitted the webs 6.

In actual field work it has been clearly and undeniably established that when a holder as hereinbefore described is in applied position upon an insulator there is a certain amount of resilient flexibility in the holder to materially reduce the liability of conductor breakage due to vibration or whippage and more particularly when the stretch of the conductor between insulators is for any considerable distance.

It has also been found in actual practice that a holder as hereinbefore described will remain tight for a time much longer than a tie wire and it has the further advantage of being easily tightened from time to time as may be required without dismantling or without handlin or" the conductor. It is also to be noted that the formation of the jaws 2, 3 and t is such as to permit the holder to be employed with conductors of different gauge and that the coaction of the holder with the conductor is such to minimize liability of endwise slippage of the conductor in case of line breakage. t is to be emphasized that a holder as hereinbefore described eliminates radio interference and that a material reduction is effected in the time required for ordinary installations and for changing insulator In the embodiment of my invention as illustrated in Figures 6 and '7 the bars a and a are constructed and formed in substantially the same manner as hereinbeiore set forth with respect to the first form of holder except that the flanges l and I extend below or beyond the webs 6 to provide ears 2?: between which are pivotally held by the cotter pins 2| or the like the inwardly disposed angular end arms 22 carried by the arcuate clamps 16'. These clamps l5 coact with the horizontal or outer groove H of the insulator A in the same manner as has hereinbefore been set forth with respect to the jaws IS in the first form of the invention. Aside from the swinging or pivotal mounting of the jaws Hi this form of the invention as illustrated in Figures 6 and 7 is substantially the same as the first embodiment and this second form of holder is installed or taken oil in the same manner as has hereinbeli'ore explained with respect to the first structure.

t is to be understood that my improved holder can be employed to advantage in connection with supports other than an insulator of the type disclosed in the accompanying drawings and can be used for purposes other than holding a high tension conductor.

From the foregoing description it is thought to be obvious that a conductor holder constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.
