INSULATOR.
Specification o! Letters Patent. Patented. March 31, 1908.
Application flled September 23, "l Serial No, 394,132.
To all whom fit may concern:
Be it known that l, EDWARD F. PADDEN, citizen of the United States, residingf at Chicago, in the county of Cook and State of l'llinois, have invented certain new and useful Improvements in Insulators, of'which the following is a specification.
This invention relates to insull'itors for electric lines or wires, and particularly to insulators used in connection with the cross arms of the ordinary poles on which the wires are supported.
The object of the invention is to forni an improved device of the kind, in which the insulator will he protected l'roin injury Vhy being located in a recess formed to receive it in the arm.
A further object of the invention is to form an insulator characterized hy improved means for holding wire in place,
The invention is illustrated in the :Lr-conn panying drawings in. which f Figure 1 is a side view of 'the insulator. Fig. 2 is an end view thereof. Fig. 3 is a side View of a cross arm with the insulator in place tl'ierein. Fig. 4 is an end view of the parts shown vin Fig. 3,
The insulator is made ol glass or similar non-conducting material, and consists of a cylindrical hody indicated at l, lwhich is threaded upon its surlace, as shown, to torni a screw, which may he screwed in the rcross arm or supportingl structure. ,At one end the hody is provided with a squared projection 2, to which a wrench or tool may he applied to turn the saine. The ho'dy is grooved lengthwise, as indicated at 3,to receive tho wire 4, the hottorn ol' tho'groove extendinpr below the hase ot the thread, so that the wire will rest helow said thread.` 'in order to hold the wire inthe groove, a glass screw 5 is provided, which is fitted into a suitable tap made in the side of the body and serving to close the groove and to clamp the wire 4 in the hot-toni thereof.
i At G is indicated a cross arm or support to which the insulator is applied. This cross arni is bored and threaded so that the body l may he screwed therein. and it is slotted as indicati-al at 7, to match with the groove in the insulator'. and to allow the wire to he entered into the insulator, The erin. is also hored lo allow the insertion of the screw 5. as indicated in Figs. 3 and et.
Aninsulator so constructed and applied to a cross arln is protected against danger oi hreakage hy stones or shots or other missiles, and at the salue time it may he readiljyT placed in or renioved 'from the socket or here formed in thel cross erin to receive it. Obviously the insulator may he used in other locations and in connection with other constructions than the cross arm of a telegraph pole.
l. claim l The combination with a support havin a threaded hole through the saine and a s ot communicating with said hole, of' an insulator connirisingl a threaded cylindrical inleg'ral hod7 screwed into said hole and having; a longitudinal groove in the side which registers with said slot and a tap in 'the side ofthe holly the groove, and a screw exy tendiiw throuoh the slot and tau and into rs rs l the groove, to hold the conductor therein.
ln testimony whereof l aflix niy signature in presence ot two witnesses.
