Cater, Kansas City, Mo., as trustee Application May 18, 1938, Serial No. 208,721 Renewed May 5, 1939 6 Claims.

My invention relates generally to means for supporting power line wire during the operation of stringing and sagging in of the wire on the poles, and particularly to an arrangement of this character for temporary installation on the pole top pin of each pole involved in the operation, the said meansbeing removable after the string ing and sagging in of the wire has been accomplished, for the purpose of being replaced by the insulator, and an important objectof the invention is to provide simple and efficient means of this character which speeds up and facilitates the operation of stringing and sagging in of the wire, and at the same time protects the wire from being burned or scratched during the operation.

Another important object of my invention is to provide means of the character indicated above permitting a greater length of the wire to be sagged without burning or scratching the wire, as would occur by presently provided means.

Other important objects of my invention will be apparent from a reading of the following description taken in connection with the drawings, wherein for purposes of illustration I have shown a preferred embodiment of my invention.

In the drawings:

Figure 1 is a general perspective view showing the means of the present invention installed on the pole top pin of adjacent poles, and with a wire strung thereon.

Figure 2 is an enlarged transverse vertical sectional View taken through one of the said means.

Figure 3 is a side elevational view of Figure 2.

Figure 4 is a top plan view of Figure 3.

Figure 5 is a side elevational view of Figure 2 taken at ninety degrees from Figure 3.

Figure 6 is a bottom plan view of Figure 4.

Referring in detail to the drawings, the numeral 5 generally designates a power line pole having the pole top pin 6 fastened to one side of the top thereof by means generally indicated by the numeral I, the upper part 8 of the pin having an irregular cross section which is slightly tapered. Onto this irregularly shaped upper part 8 is temporarily placed the device of the present invention which is generally designated by the numeral 9 and which comprises a casting in the form of an elongated polygonal-shaped base It having outwardly inclined circular pins 5! and i2 rising from the outer ends thereof, with webs I3 and I4 on the bottom of the base or plate IE3 and aligned with the pins and extending from a point under the pins to the depending tubular part I5 which has a lower bore portion I 6 which is similar in cross section to the irregularly shaped upper part 8 of the pole top pin 6 and which is designed to snugly receive the pole top pin in a manner so that the base IE) will not revolve relative to' the pole top pin 6, and with the pins II and I2 arranged transversely of the direction of the power line or wire H. The upper end of the lower bore portion I6 leads into a cylindrical upper bore portion I8 of a hollow stub axle I9 on which is rotatably mounted a wooden or other suitable material sheave 20 formed with a groove 2| in its periphery, the wider lower flange 22 and the less wide upper flange 23, the space between the flange 23 and the pins II and I2 being sufficient to accommodate entry of the wire IT. A bearing washer 24 is circumposed on the stub axle I9 below the sheave while another bearing washer 25 is circumposed on the stub axle I9 above the sheave and resting thereon, and a cotter key or the like 26 traverses the upper end of the stub axle I9 to hold the washers and sheave in place on the stub axle I9.

In use the wire to be strung or sagged is placed in the wooden sheave 20 on the outside of any angle which the pole top pin or the pole may be in, in the line of poles. The wire I1 is then pulled to the proper sag, the sheave being free to turn on the casting, thereby permitting a far greater length of wire to be sagged and avoiding the danger of burning or stretching the wire. After the wire is properly sagged the device is removed and the insulator or other such fitting is put in a proper place on the pole top pin, the wire then being tied or fastened in any desired manner to the insulator.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in the materials and in the structure and arrangement of the parts. within the spirit of the invention and the scope of the subjoined claims.

Having described the invention, what is claimed as new is:

l. A device for stringing and sagging a power line comprising a base, a depending sleeve on said base to removably receive therein an insulator supporting pin to arrange said base on a power line pole, upwardly and outwardly extending spaced guide pins carried by the base, a vertically arranged axle on said base between said pins, and a horizontally arranged sheave journaled on the axle between said pins and including upper and lower flanges, the upper flange being of a smaller diameter than the diameter of the lower flange to permit a line to pass between said upper flange and one of the pins onto the sheave.

2. A device for stringing and sagging in power lines comprising a base having an opening of irregular transverse cross section therein, said opening being adapted to receive an insulator pin of similar irregular transverse cross section whereby said base is mounted and secured against rotation on the insulator pin, a sheave rotatably mounted on said base, upper and lower flanges on said sheave, and spaced guide members extending from said base in close proximity to the periphery of said lower flange and into spaced relationship to the periphery of said upper flange.

3. A device for stringing and sagging in power lines comprising a base, a depending tubular sleeve on said base, said sleeve having an internal bore of irregular transverse cross section adapted to receive an insulator pin of similar irregular transverse cross section, a hollow stub axle extending upwardly from said base and having an internal bore forming a continuation of the internal bore of said sleeve, a sheave rotatably mounted on said stub axle, upper and lower flanges on said sheave and spaced guide members extending from base in close proximity to the periphery of said lower flange and into spaced relationship to the periphery of said upper flange.

4. A device for stringing and sagging in power lines comprising a. base having. an opening therein of irregular transverse cross section to receive an insulator pin of similar irregular transverse cross section, a sheave rotatably mounted on said base, upper and lower flanges on said sheave and spaced guide members extending from said base in close proximity to the periphery of said lower flange and into spaced relationship to said upper flange.

5. A wire stringing and sagging in device comprising a base, said base having an opening of irregular transverse cross section therein and adapted to receive a pole top pin of similar irregular cross section whereby said base is secured against rotation on said pin, a stub axle extending upwardly from said base, a sheave mounted for rotation on said axle, upper and lower flanges on said sheave, and spaced guide pins carried by said base and lying in close proximity to the periphery of the lower flange of said sheave and in spaced relationship to the periphery of the upper flange of said sheave.

6. A device for stringing and sagging in power lines comprising a base having an opening of irregular transverse cross section therein, said opening being adapted to receive an insulator pin of similar irregular transverse cross section whereby said base is mounted and secured against rotation on the insulator pin, a sheave rotatably mounted on said base, upper and lower flanges. on said sheave and at least one guide member extending from said base in close proximity to the periphery of said lower flange and into spaced relationship to the periphery of said upper flange.
