Application filed June 17, 1908. Serial No. %38,:93.

Z all "whom it may concern:

le it known that we, SAMUEL BARTLEY and WILLIAM O. BARTLRY, citizens of the United States. residing at Calhoun, in the county of Richland and State of Illinois, have invented new and useful linprovcments in insulators, of which the following is a specification.

lhis inventionrelates to electric-wire supports and insulators ol' the type shown in our Letters-Patent Number 836,916, granted July 24, 1906, wherein a. sectional insulator is held within a divided or se tional casing, and constitutes an improvement upon the construction of insulator disclosed therein the particular object of the present invention being, first, to provide means 'i'oigpreventing the entrance of rain, snow or sleet at the ends of the casing and to protect the ad jacent portions of the wire, and, second, to provide means for securing an eiiective ventilation 01' the insulator or circulation of air through the same and around the clamped portion of the wire.

In the accompanying drawing, Figure 1 is a front elevation of the insulator, with the lower end of the supporting pin broken'away.

- Fig. 2 is a bottom plan view of the top section of the insulator casing and the insulator section contained therein. Fig. 3 is a top plan view of the bottom section of the insulator casing and the insulator section contained' therein. Figs. 4 and 5 are vertical transversesections taken on different lines through the closed insulator.

Referring to the drawing, the numeral 1 designates the supporting pin'o'f the device, which'may boot the constructi n set forth inour aforesaid patent to securet e insulator to a pole or other support, and which is fixed to and depends from the lower half .or section 2 of the insulator casing 3, which includes a similar upper half or section 4. The casing '3 is thus composed of two longitudinally-divided or semicircular sections, as shown, the bottom one of which is adapted to be rigidly secured to a suitable support.

Suitable means are provided for'connecting and locking the two sections together, which may be the same as that disclosed in our patented structure. As-illustrated, the bottom section 5 is formed on one side with a pair of receiving or keeper hooks 5, one located near each end thereof, which hooks are adapted to receive retaining lugs 6,

formed upon the contiguous side of the top section 4. The opposite or front sides of the casing sections 2 and 4 are respectivelyprovided at an intermediate point withlocking lugs 7 and 8, adapted tov be engaged by a locking plate 9. The plate is formed with an oblong opening toadapt it to be fitted over upon said lug, the lug 7 being provided with an undercut surface 10 and the lug 8 with a series of locking teeth 11 for a locking engagement of the .plate therewith, as fully set forth in said patent. Any other suitable type of connecting and locking means may,

however, be employed.

sulator sections may be formed of glass, por celam, rubber, fiber or any other suitable 1nsulati-ng material, and the meeting faces thereof are PI0Vl( l-.'-(l with central coinciding recesses 14 for the passage of the wire, which Til extends longitudinally through the casing,

the said recesses being preferably of angular form so that the walls thereof will firmly clamp the wire in position.-

In order to'provide for the free passage of the wire and to obviate liability of contact between the same and the casing, the sections of the casing are respectively formed withsemicircular openings 15 and 16 of sui'licient diameter to dispose the metal of which the casing sections are 1 preferably made a distance away from the wire. When the casing sections are closed the wire will extend longitudinally through the recesses 14 and openings 15 and 16, and in order to protect the adjacent portions of the same and toprevent entrance of rain, snow or sleet to the ends of the casing, the ends of the top section 4 are provided with semicircular hoods or shields 17 to overhang the Wire and extend outward a suiiicient distance to guard the openings.

The insulator sections are respectively provided in their meeting faces With outwardly flaring cavities or recesses 18 and 19 which communicate at their inner ends with the recesses 14 and at their-outer ends with the respective openings 15 and 16, and inter
