WIRE CLAMP AND INSULATOR HOLDER.
Application flledJuly 2, 1927. Serial No. 203,232.
This invention relates to electrical conductorholders and its general object is to provide a combined clamp and insulator holder for conductors that not only threadedly receives an insulator but includes means for securely clamping the same thereon, with the result the insulator cannot work loose under strain or movement of the conductor which is also clampedto the insulator by a 1 portion of my device.
Another objectof the invention is to pro vide a conductor clamp and insulator holder, that is capable of being secured to a cross bar of a pole, in an easy and expeditious manner and so that casual disarrangement or displacement thereof is practically impossible.
' This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.
In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views,-and in which: 7
Figure 1 is a side elevation of my invention and shows. the same in applied position to a cross bar of a pole and receiving a conductor wire.
. Figure 2 is a top plan view thereof.
Figure 3 is a sectional view taken on line 3-3of Figure 1. o
Figure 4 is a longitudinal sectional view taken through the device Figure 5 is a-perspective view showing the position assumed by the-clamping means before it is applied to a conductor.
Figure 6 is a top, plan view of the msulator holder perse.
' Figure 7 illustrates the application of slightly modified forms of the device to the cross arms of a pole.
Figure '8 is a rear elevation of one of the modified forms as shown in Figure 7 and which is adapted to replace the wooden pipe holders as suggested therein.
letter A indicates a fragmentary portion of a cross bar of a pole and towhich is secured the insulator holder which includes a flat elongated body strip 1 provided with spaced parallel openings 2 to receivesecuring bolts Referring to the drawings in detail, the
3 as clearly shown in Figures 1 and 2 of the drawings. Integrally formed with one end of thebody strip 1 is a curved arm 4 which terminates in parallelism With and above the planeof the body strip 1 and formed on said arm 4 is a threaded shank 5 arranged to overlie the body strip as best shown in Figure 4. The shank 5 is tapered in the usual manner and is adapted to receive an insulator B of the usual construction. Formed integral with the shank and at its juncture with the arm 4 is a substantially V -shaped projection 6 which extends rearwardly and upwardly from the shank in a mannerto provide a recess 7 for a purpose which will be presently apparent.
' The insulator B is threadedly secured to the shank 5 in the usual manner, and in order to prevent. casual displacement of the insulator B, and to fix a conductor thereto, I have provided a substantially bail shape member formed from wire and includes parallel arms 8 adapted to extend longitudinally of the insulator upon diametrically opposite sides thereof as best shown in Figure 2 and these arms 8 have formed on one end converging portions 9 which terminate into a straight part 10 to provide a bearing for receiving a spool 11 having a concaved outer surface so as to be snugly accommodated in the recess 7 as best shown in Figure 2 of the drawings. The arms 8 have their free ends bent outwardly at right angles upon themselves to provide conductor receiving portions 12, while fixed to the arms 8 adjacent their juncture with the portions 12 is a substantially U-shaped wire member 13 adapted to be received in the circumferential groove C of the insulator B, and the conductor which is indicated by the letter D is curved so as to be received in the remaining portion of the groove C and is held therein by winding the portions 12 thereabout as best shown in Figure 2.
It will be obvious fromthe above that I have provideda combined clamp and insulator holder that performs a dual function for securing the insulator B to the holder, as the insulator B is threadedly secured to the shank 5 and is further held in operative position thereon through the instrumentality of the bail which includes the arms 8 and the engagement of the spool 11 with its recess 7 as best shown in Figure 4 of the drawings. Again, the insulator holder is secured to the bar in a manner whereby lateral strain or constant movement ot the conduct will not displace the same nor will the ii. ulator 3 he displaced by such strain or movement. ll hile h re shown my insulator hold t fixed to a c u bar it of a pole, 1 want it undr it can be associated with any "ting means secured to a pole or otl er and it can be secured directly to the pole or any other place Where a device of this character needed.
In .l igure T l. have illustra d the application ot in holder in other tor is to the cross arms oi 's pole, and it will be noted that a pliiralit of bold oi the form just descrihr-d are fo med in parallelism 'ith a single strip is which is to be secured to the cross arms by bolts asshovvn. The upper cr arm in Figure 7 is arranged at an inclination and secured to the pole accordingly, so as to be properly braced, due to the fact that the conductors that are adapted to be secured to the holders of this cross arm are to mal-te a turn from their securing point. in an opposed direction to the angle oi" inclination of the cross arm.
For repairing old lines, I provide a strip holder as best shown in Figure and this holder includes the curved arm l, and the threaded shank 5 for receiving the insulator B which is secured thereto b the same means and in the same manner as in the other forms, but it will be noted that the arm has formed therewith and depending therefrom a ti -shaped strap 17 with aligned openings in its arms to receive a bolt and nut connection 18 for securing the holder to the lovver cross bar as shown in Figure T.
It thought from the foregoing description that the advantages and novel features of my invention will be readil v apparent.
I desire it to be understood that 1 may make changes in the construction and in the combination and arrangement of the sev eral parts, provided that such changes fall Within the scope or the appended claims.
