Application filed September 8, 1921. Serial No. 499.295.

The invention relates to insulators, and more particularly to improved means for connecting insulators to guy ropes and simig lar members.

The inventionrelates to improvements in" the connecting device illustrated and de scribed in the copending applicationf of Minor F. H. Gouverneur, filed September 8, 1921, Serial No. 499,172. y

The principal object of my invention, gen

erally stated, is to simplify the connection between a ball strain insulator and a guy rope or the conductor terminating on tower or pole.

- To this end I provide a simple, reliable and economical connection adapted to be engaged by thelinemen without the use of tools other those those usually carried by those men.

In the drawings, wherein I have illustrated a single embodiment of my device, v

Figure l is a view in side elevation of a ball strain insulator showing the improved form of connectorapplied thereto.

Figure 2 is a transverse Vertical section of Fig. 1.,

Figure 3 is a perspective view of the connector showing the same unlocked or in con dition to be assembled with an insulator.

Figure l is a section on line 4 l of Fig. 9.

Throughout the specification and drawings like parts are designated by like reference characters.

In the particular embodiment of the device here illustrated the conventional type of ball strain insulator is indicated by the reference numeral 1, It might be here pointed out that although I have shown my connector with a ball strain insulator, I do not limit my device to use in that connection, since my form of connecting device may advantageously be employed with many other types of insulators, as will be readily apparent to those skilled in the art.

The insulator 1 is provided on its exterior surface with a plurality of outwardly projecting wings or fins 2 the purpose of which is to increase'the surface leakage distance between the parts of the connector. Passing between the alined pairs of the projections 2 are openings 3 suitably spaced from the ends of the insulator and arranged at right angles to each other. The upper face or surface of the lower opening and the lower face of the upper opening 3 are preferably provided with curved surfaces 4, as clearly indicated in Figs. 1 and 2. I

To connect the insulatorto a guy rope or to the tower carrying the transmission line, I provide a connecting device generally designated by the reference numeral 5. This de- V106 preferably comprises a loop member '6 anda link member 7 .Said'link is for convenience formed from a ring having the adj 21- cent ends thereof welded together. The ring is then fiattenedorsuitably shaped into the form shown most clearly in Fig. 3. v

The loop member (i is provided at its free ends with integral hooksS which engage the coacting'ends of the link member 7.

It is the custom to provide strain insulators of the typeillustrated with-openings having a maximum diameter of approximately "three (piarters of an inch, and in fact it is of vital importance to limit the size of the openings in all insulators. The connecting device is preferably formed with a wire having a di ameter of one quarterof an inch, since wire of this gage has a maximum strength far in excess of that required for a connector in an insulator. It is to be observed that the flattenea ring forming the link member 7 and likewise the hook portions 8 of the loop memher 6, have a maximum width which permits either the hooked end of the loop member 6 or the looped ends of the link member 7 to pass freely through the opening in the insulator. y 7

To connect the device the link member 7 is preferably joined to one of the hooks 8 of the members 6 as shown in Fig. 3. The opposite leg of the loop member 6 is then passed through the opening in the eye bolt or looped end of the guy rope, as the case may be, and

the link member 7 is then insertedwithin the opening The curved face of the link memher is preferably symmetrical with the curved bearing faces l of the insulator and the link I is associated with the insulator in such mannor as to bring these curved bearing faces in to engagement. The open hook of the opposite leg of the loop member 6 is then forced into coupling engagement with the free end of the link 7 and is then forced upwardly into substantially the position shown in Fig. 2. In assembled position the bills 10 of the hooks 8 are substantially parallel to the walls of the insulator against which they contact. This engagement holds the ends of the hooks in fixed position so that strain upon the loop member serves to force the latter into close engagement with the ad] acent members. The

llU

Wire is of suiiic'ient rigidity to prevent the flexing of the hook portion under strain. By my arrangement I provide a simple form of insulator connecting. mechanisinin which the greaterthe strain placed upontheiinsulator the tighter the connection between the parts of the connector becomes.

1. The combination with an insulator of the strain, type provided. with a: plurality of curved passages therein, of means for 0011- necting saidinsulator to an adjacent memher, said means comprising a pair of coacting' members, one of said last named members Conforming to and being adaptedto extend through one of the said passages in said insula'tor. the, other 'coacting member. having integral hooksfor connecting the said members, the ends of the hooks engaging against the sides of the insulator and being held closed thereby for preventing the disengagement of said co'acting members.

p I 2. Supporting means for a strain insulator having curved passage therethrough and longitudinal grooves merging thereinto, comprising a link adapted to be located Within said passage and terminating in eye portions, and a loop including arms having their ends formed with inwardly extending hooks engageable Within said eyes, the bill portions of the hooks engaging against the insulator at the bottom of the grooves therein whereby the hooks will be maintained closed to prevent disengagement thereof from the link.

Supporting and connecting means for an insulator having a passage therethrough, comprising a link adapted to be disposed within said passage and formed as two curved integral arm portions connected by eye portions,- and a loop having a pair of arms terminating in hooks for engagement within said eye portions, one hook being initially in engagement with the link and closed and the other hook being initially. open, said hooks having bill portions directed toward each other and said bill portions engaging against the opposite sides of the insulator and being held closedthereby. y

In testimony whereof I affix my signature.
