Application filed May 31., l 9l0 Serial No. 564,032..
To all whom it may concern Be it known that I, MIhLARn E. Sroon- WELL, a citizen of the United States, residing at Les Augeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Insulators, of which the following is a specification.
.This invention relates to insulators and particularly to the insulator pins which support insulators such as are used for supporting line wires of electric circuits.
The object of the invention is to produce an insulator pin which will be very inexpensive to manufacture and which can be readily attached to the side of a pole or in a cross-tree carrying the insulator. The pin is constructed in such a way as to facilitate the attachment of the insulator to the pin.
In the annexed drawing which forms a part of the specification attached hereto, Figure l is a vertical section through a pin constructed according to my invention, and
showing the arm or cross-tree to which the pin is attached in cross-section. Fig. 2 is a sect-ion taken at the side of the pin through the arm or cross-tree showing the pin in elevat-ion, and further illustrating the means for screwing the pin to the arm. This view also shows an insulator tip which I employ on the upper end of the pin, and under the dome of the insulator. Fig. 3 is a plan of the pin shown in Fig. 2. .Fig. 4 is a front elevation showing a pin of modified construction, and adapted to be attached to the arm or cross-tree in a different manner. Fig. 5 is a side elevation of the pin shown in Fig. i.
Referring more particularly to the parts, 6 represents the arm or cross-tree to which the pin 7 is adapted to be attached. This arm is provided with a vertical bore [8. The pin 7 is adapted to be formed of sheet metal, bent so that the body of the pin forms a cylindrical roll or shank 9, it is adapted to be compressed slightly and introduced into the bore 8 from. above as indicated. The upper end of the pin presents a tapered nipple 10, which is offset so as to form a screw thread 11. By means of this thread 11, the insulator 12 is attached, the said insulator being of tapered form, and having a tapered threaded bore 13 formed therein as indicated. On account of the fact that the pin 7 is "formed of sheet metal, it presents a longitudinally disposed groove or slot 14, which is formedbetween the edges Specification ofLetters Patent.
Patented July 31,3913. Renewed November 16, 1912. Serial No. 731,897.
15 of the blank which are disposed near each other as indicated in Fig. 2. This. slot 14, extends continuously from end to end of the pin. In addition to the slot l t,
' provide the nipple 10 of the pin, with other slots, 16, which extend downwardly from the upper end of the pin as indicated-in Fig. 3.
In. this way the upper end of the pin is formed into. three, (or more if desired) re-' silient tongues 17. In attaching the pin to the arm 6, th shank 9 of the pin is introduced intothe bore with the slot 14, disposed toward the side of the arm, and I then drive fastening devices such as nails 18, inwardly through the side face of the arm, and'through the slot 14:. These fastening devices are pointed ,at their forward ends so as to assist their passing through the slot, and they operate to expand the shank 9 so that it fits tightly in. the bore 8. At the same time they operate to bend the edges 15, so as to form small notches l9, and. these notches tend to prevent the pinnirom being withdrawn from the arm. The line wire 20, may be attached. to the insulator in any suitable manner as indicated. 1
Theinsulator 12 is screwedon to the nipple in the usual manner, and on account of the resiliency of the tongue 17, it can be seated very securely on the pin. In order to limit the inward movement oi the tongues 17, I may provide an insulating button 21, on the upper end of the pin, the body of which extends down into the interior or the pin, and this button is received in the upper end of the bore of the insulator 22, as indicated in dotted lines in Fig. 2.
In some cases, especially where the pin is to be attached on the side of a pole, or on the side of a building, I provide the construction shown in Figs. 4 and 5.- In this form of the device the pin is formed from a blank of sheet metal which is bent so as to form an elongated welo or base plate 23, having laterally projecting side flanges 2a, and the upper portion of the blank is bent so as to form a tapered nipple 25 similar to the nipple 10 already described. The edges 26 are disposed apart so as to form a longitudinally disposed slot 27 which extends throughout the cntire length of the nipple, and this slot is disposed opposite to the web 23 as indicated. At a suitable point the web is provided with an opening 29 through which fastenihg devices may be appliedto secure the pin to the side of a pole, or to the side of a building. As in the other form of the invention, the nipple 24; may be provided With several longitudinall disposed slots which increase the flex'i ility and resiliency of the nipple when the insulator is screwed upon it.
The-insulator pin is preferably formedot sheet metal or similar metal having consid;
erable resiliency.
Having described my invention What I claim as new and. desire to secure by Letters Patent is:
1. An insulator pin formed of sheet metal, having a shank adapted to be attached to a support, and having a tapered nipple at the upper end thereof, with a longitudinally extending slot in the Wall thereof, said slot extending the entire length of said Wall.
2. An insulator pin formed of sheet metal, having a shank adapted to be attached to a support, having a tapered nipple formed at the upper end thereof, saidnipple having a plurality of therein, an m ans to expand said pin after inserti n int said support.
3. An insulating pin adapted to be formed of sheet metal, having a shank in the form of a cylindrical roll, and having a tapered threaded nipple at the upper end thereof, said pin having a slotextending longitudinally from end to end thereofiand having other slots extending longitudinally on said nipple, and means to increase the diameter of said pin when the same is in a fixed position. 4
4, An insulating pin having a shank in longitudinally disposed slots the form of a roll with an arm having a bore e i g said Shank, said pin provided with llgitlldlnally extending slot, and fastenng d ices screwed in said arm and passing I'Q lg-h said slot, said devices adapted to xpand said shank tightly in said bore.
5; An insulator pin of tubular form, having a nipple formed at the upper end thereof, said nipple having a longitudinally slotted Wall, an insulating button seated on the upper end of said nipple, and an insulator seated on said nipple over said button, said button adapted to limit the contraction of said nipple When the insulator is seated thereon.
6. An insulating pin of tubular form having a longitudinal slot and having a nipple formed at the upper end thereof, adapted to receive the insulator, an insulating plug seated in the upper end of said nipple and adapted to limit the inward movement of the Wall thereof, and an insulator mounted on said nipple over said plug.
7. An insulator pin of tubular form adapted to be received in a bore, means for expanding said pin its entire length in said bore to hold the same securely therein, said pin having a nipple formed at one end thereof adapted to receive an insulator.
In Witness that I claim the foregoing I have hereunto subscribed my name this 23 day of May 1910.
