T LEVEBPOGL, (Hill). A COBEGRATIQN 0F SUSPENSION-INSULATOR EYEZBGLT.
To all whom'it may concern:
Be it known that I, J osnPH ADDISON SAND- FORD, Jr., a citizen of the United States of America, and residing in the city of East Liverpool, in the county of Columbiana and State of Ohio, have invented'a certain new and Improved Suspension-Insulator Eyebolt, of which the following is a specifics -sion insulators,
tion.
. My invention relates to insulator eye bolts and particularly to an eye hell; for suspenthe object of my invention being to provide an eye bolt of this character which forms t joint'of improved mechanical efliciency with the insulator head when cemented in position;
In the accompanying. drawing :-Figure 1 is a vertical section through a suspension A riding a more efficient mechanical joint be.
my improved eyebolt in position; Figs. 2 and 3 are elevations at right angles to' each other, of the eye bolt alone and drawn to a larger scale.
Suspension insulator units are commonly insulator showing.
uuitedby means eta metallic eye bolt cemerited at one end in the heiad of the insulator and extending below'the latter suflitwcen the pin and the head of the insulator. To this end I make the shank of the eye bolt, viz., that portion which is embedded incement in the head 5 of the ini sula'tor 6, of greater diameter than hashere tofore been customary and of slightly conical. shape throughout the major portion of its length. A series of transverse annular ribs or corrugations 7 are formed on this shank, and the terminal rib 8 is enlarged to form a cap approximately the least internal diameter of the insulator head.
' Longitudinal ribs 9 of which two are shown,

extend from one end of the shank to the other." v
The eye end of the bolt is here shown as a flattened Web 10 perforated at .ll'to receive the pin 12 which passes through the lugs 13' on the cap M cemented on the head of the insulator. The perforation may be i of any desired shape and the eye may be formed in other waysif desirable;
An eye. bolt of this construction, by resson of its greater diameter of shank, requires a less body of cement 16 than has heretofore been necessary to use,and consequcutly there is less danger of the turbed before the cement has set during the course of its manufacture. The conical the cement dries more quickly and.
boltbeing disinclination oi the shank body and the enlarged cap corrugation 8. result in the formation of an annular slightly Wedge-shaped body of cement surrounding the shank and engaged by the ribs 7 on the shank and the ribs 17 on the inner face of the insulator head. which is of great mechanical strength. The longitudinal ribs 9 on the shanlr'also engage the cement and the bolt is thus prevented from swiveling.
Obviously the precise formation of the transverse and longitudinal ribs maybe varied within the scope of my invention,
as also thedegree of conicity of the shank shown.
l claim as my mvent1on:--
and of the size of the head rib, and I up not limit my invention to the precise structure I A connecting belt for suspensionlinsulm v tors comprising an eve portion and a shaii'k portion adapted to be cemented in theinsulator head. said shank portion being genorally conical in shape with transverse and longitudinal ribs. and, at the inner end of the shank adjacent. the reduced portion thereof. an enlarged annular rib forming a can. substantially as described.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses.
