To all wif/,071e if; naar] concern): v g
Be it known that i, HENRY l). Srnorrnn, a citizen of the United States, residing at Oregon, in the county oi @gie and State oi Illinois, have invented certain new and usefullmprovements in insulators, ol`l which the following is a speciiication.
The object of this invention is to construct an insulator for electrical line wires and consists of two metallic sections, each supporting a section of insulating material and cach section of insulating material supporting` metallic late between which the line wire Ais received? and means for clamping the opposite metallic sections together. f
In the accompanying drawiiws Figure 1 is l w h y an isometrical representation olv my un- Fig. 2 is a vertical transproved insulator. verse section.
The lower section 1 oi the insulator is in semi-cylindrical form tapering toward the ends. The upper surface of this lower section is hollowed out and within the cavity is a porcelain body 2 having its upper face recessed, and within. the recess is located a metallic plate 3 having its upper face provided with a lengthwise semi-circular groove 4, having its bottom serrated. vFrom the 'upper face of the lower section extends a rib l l 5 along the-two sides thereof. From enel edge of the lower section extends a llange 6 having a screw threaded opening T. `lfrom the other edge of the lower section extends a erforated ear The under .tace of the lbwer section has a screw threaded opening 9. l A shank 10 has its upper end screw thread- I ed and is located in the screw threaded opcnl ing of the lower section. 'lhe lower end et l this shank is screw threaded 'to receive a nu t l 411. The upper end oi the shank .11) has an l' enlargement 12 and from its lower Ytace 0X- l tends two prongs 13; y l The upper section 14- ol the insulator is l identical with the lower section so l`ar as rel lates to the porcdain center 15 and the mctall lic plate 16. The underlnce el the upper l section has a groove 17 along its sides, which is of a size and depth to receive the ribs 5 ol l the lower section. From one edge of the upper section extends a perforated ear`18, and from the other edge olZ the upper section l extends two lugs 19 from which extends the covering 20. These lugs 19, in connection with the ear S of the lower section, through which extends a pintle 21, form a hinge convuection between the two sections of the insulator, and the covering 2() extends over the hinge and protects it l'romthe rain. The lower end ot' the shank is placed in an opening in the cross arm. The prongs 13 are driven into the cross arm and the shank is held in connection therewith by the nut 11. The lower section ot the insulator is turned in connection with the upper screw threaded end ol the shank. Aline wire 22 is placed in the semi-circular groove in the lower section, and l the upper section of the insulator is turned over the lower section and held there by the thumb screw 23 passing through the opening in the flange ot the upper section into the screw threaded opening 7 in the flange of the lower section. As the grooves of the plates 3 and 16 are roughed or serrated the wire will be held iirinly in contact therewith. It will be noticed that the ends ol the plates 3 and 1G are cut away or beveled, which permits the line wires to move laterally a given distance and also prevents water from entering between the sections of the insulator. By the employment ol my improved insulator the line wires can be quickly clamped in place in connection therewith and can be easily removed therefrom. The porcelain sections 2 and 15 prevent the groundingl oi! the wires.
lt is evident that glass or other"suit'able insulating material may be employed in place oi the porcelain and still be within the scope of my invention.
.l claim as my invention' An insulator comprising two halves hinged together, means for connecting their l're'e edges, their meeting faceshefch havinga section ot insulating material 'xedlyconnected thereto and each section of insulating material having :almetallic plate ixedly connected thereto.
