INSULATOBi Specification 0 Application tiled February To all whom it may concern:

lie it known that l, Funnnmon Josnru lhun, a citizen of the United States, residing at 'est Lebanon, in the county of Varren and State of Indiana have invented certain new and useful Improvements In Insulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertams to make and use the same.

My invention relates to new and useful improvements in insulator attachments and more particularly to that class adapted to telephone, telegraph or electric wires, an my to provide means for securing the insulating devices to the usual form of cross arm carried at the upper end of support' poles.

A further object is to prev] e means whereby the insulating blocks may be read ily attached to the wires.

.-\-still further object is to provide means for clamping the parts of the insulating device around the wires.

Other objects and advantages will be hereinafter referred to and more particularly pointed outin the claims I Inthe accom anying drawings which are i this application, Figure 1 is} a side elevation of my improved insulater and securing device therefor. Fig.2 is

and to obviate this result, I provide a metal standard the lower end of which is in :r-vduted through an opening 3 in the cross arm, the downward movement of the stand ard being limited by means of a conical collar 4-, while the extreme lower end of the standard is threaded to receive a nut 5, by which means the standard is secured to the cross arm.

That portion of the standard above the collar 4 is divided into two sections 6 and 7, the section 6 being integral with the standard while the section I is pivolally secured ing a pivot, pin 8 through the standard 2 and the extreme lower end of the section 7. The sections 6 and T are provided adjacent their upper ends with semicircular clamping members 9 and 10. respectively, said members having re ering cavities 11 and 12, respectively w ich are adapted to receive insulating blocks 13 and 14, res t-ively, th block 13 havin" a rib 15 exten ng longitudinally thereof, while each edge of the block 14 is provided with a flange 16 adapted to extend at opposite sides of the rib l5 and clamp the wire 17 over the curved fare of, the rib, said rib having a depression l8 atits longitudinal center to 'iorm a seat for the wire, the inner faces of thefianges 16 being rounded, thus obviating the pumihilit of cutting or injuring the and at the same t-ime'grip the same with-sufiicient tension to revent'lo "tudinal movement lqf the-wire etweenthe locks. ;The extremeupper ends of the sections 6 d fil are secured together by means of a mgn atits lower end to the standard by introducextend wheiifturlie d I e h lnmp ngl olt 22,

made much smaller than if constructed of wood, thereby requiring a smaller openinf; through the cross arm to receive the slant ard, while, by forming the collar -1 integral with the standard and providing a tapered upper surface therefor. water, or the like, will be prevented from entering the opening 3 in the cross arm when said collar is firmly clamped in position on the arm.

In securing the wire to the standards the two sections of the standards are separated and the wire placed in position between the insulatii'ig blocks. after which the section T is swung upwardly and the block 14 moved into engagement with the block 13, when the clamping bolt '22 is swung downwardly between the cars 24 and the wire firml clamped between the blocks hv turning the wing-nut onto the clamping bolt, and .b v pro riding a convex surface or rib on the block 13 and flanges on the fare of the block 14 between which the rib the wire will be crilnped over the rill and securely held against longitudinal movement, thus holdin the wire taut between each set of stand ar ds. It will thus be seen that I have provided a means for securing insulators to so porting arms wherein the insulator may quickly secured to or removed from the se curing device and it'- will likewise be seen that by providing the clamping mechanism-as shown, the wire to which the insulator is attached. may he held taut along the line of posts from which said wires are 5115 l fl' What- I claim is:

1. The herein described insulating device, comprising the combination with an arm; of a standard adapted to be secured to said arm, a collar on said standard, the upper face of which is in d, sections above said standard, one of w ich is integral with the standard and the opposite section pivotally secured thereto, cla ing members adjacent the it per ends of sect-ions hat cavities t emin, insulating blocks adap d to.

enter the cavities and means atthc 11 per the sections of the insulator v ends of the'sections of the standard nip an insulating device of {the Yclnss3iiescribed comprising the a standard having sections at one end thereof, one of which sections is integral with the standard and the other section hinged there to, clamping members adjacent the upper ends of said sections having cavities on their inner faces. cars at the upper ends of said sections, a clamping bolt. pivoted to the ears on one section and adapted to extend between the ears on the opposite section, shoulders on the pivoted section and a wingnnt for said bolt; ado ted to clam the ivoted section against tie fixed section; 0 an insulator formed in two sections, one section having a rib and a wire receiving groove extending transversely of said rib and flanges on the opposite section of the insulator adapted to cooperate with the rib on the first-mentioned section of the insulator and ela m a wire passing between said sections.

3. u an insulator attachment, the combination with a standard havi w one of its ends threaded. a collar intcgra with said standard and having a tapered upper face, sections at the 1: per end of said standard, one of which is h xed with the standard and the opposite section pivoted to the standard, clamping members adjacentthe up or ends of said sections having cavities in meet ing faces thereof, cars at the upper ends of said sections, one set of said ears having shoulders, a clamping bolt; pivoted between one set of cars and adapted to extend "between the opposite ears, a nut; on the free end of said bolt adapted to hold the pivoted section in juxtaposition to the fixed section, said nut extending below and 0 :mid shoulders when the sections their closed positions; of an insulator fanned in two sections and adapted to fit: in the cavities in the elm-aging members and be held together there y and means to prevent longitudinal movement of a wire said insulator-sections.
