Theinvention relates to means for connecting the suspensionV links of Hewlett type insulators. v

The principal object vof the invention, gen- 5 `-orally stated, is to providefinsulator link conv necting means embodying counterpart mem- Vbersjengageable `upon the ladjacent ends of links and equipped with means for preventing Y eration. y Y -he object of the invention, more partlcuilarly stated, is to provide insulator link confnecting means comprising` counterpart clamp members which `may be formed as castings and which are held in assembledrelation by '15 abend or ring engaged thereabout,`the construction .and arrangement .being such that nassemblingmay `be easily-ei'ected in midair as is sometimes necessaryv in such Work.

Another object .of theinvention is the ro- Y Se m v vision of means of this character'in W ich Y vthe counterpart. members are so formed as tohtake the longitudinal strain instead ofrit comingk to any great extent upon theband or ring which holds them assembled.` J4A `further object of the invention is the proyvision of a connecting device in which the cast counterpart members are of such specific L'formation as to be capable of being easily dressed or ground at their confrentingg faces and at the surfaces engaged by the retaining band or ring, the major portions of the con- 4frontingfaces being sunk so as to minimize the area to be inished. Y I Yet another object ofthe invention isthe @provision of al connecting device of thischaracterjin which the holes provided for'the passage of the links are fiared soA asto remove the. burr to a oint remote from' the v link, the Haring ^furt ermore ermitting limited move- 40 `mentoffthelinks wit respectto theconnec'ter so that the parts may adjust themselves properly to the line ofstrain, other detaile features Iin vthe construction being provided for the samefpurpose. f

sun more Specifically, the obje-@sof the in'.

o c n q l i. if Figure 2 1s across sect1onal .vlewthrough commodation .fof substantially V.Uh-shaped links. Obviously, some `means mustV be provided for connecting thesuccessivelinksyin order to form. an insulatorv string-Aanditj' is( with this object in view that I have designed lthe present invention.v- In. the present 1inn stance the links 1 areshown as having their arms 2 terminating in heads 3 which arepartially spherical in shape.

to the ends, these recesses communicating with n openingsS in the end portions, the openings 8 having their outer cated at 9 for the two old purpose of permitting a certain amount of play with respect to the links and removing the burr, formed in casting, to a point remote from the link.

f Such a burr may, if desired, be `readily 4removed by grinding though inasmuch as it is not adjacent the link its presence cannot Work any material disadvantage.- The recesses 7 are of slightly greater size'than the heads 3 `'so asto receive them easily Without any danger of binding, play being desirable for the further-reason that the various parts may then accommodate themselves morereadily to the line of strain when assembling has been effected. l

The members .tare formed centrally With Y an outstanding'rib l() Which* is preferably f ground o or dressed to have anioreor less` smooth surface of comparatively true cylindrical form for engagement thereon of a ringor band 11 which is disposed in embracing or encircling relation tothe counterpart vmembers for holding them in assembled relation. In order that the band maybe held against displaeement,it is preferably cut along spaced parallel lines 12and transversely as shown at 13 to define an elongated tongue 14 of a more Vor less resilient nature@ The members Il are l formed centrally of the outstanding ribs l0 with grooves l5 which mate to. define a continuous channel about a pair of the assembled members.

In assembling, a pair of the counterpart members are engaged upon adjacent links, the

heads 3 of the latter being received Within the'v recesses or sockets 7 the links themselves extending through the openings 8. The band 1l is then 'slipped onto the assembled members by longitudinal movement With respect thereto and the tongue 14 is bentv or forced inwardly-by any suitable means so that it will engage Within the continuous vgroove l5, thereby preventingdisplacement of the band or ring.

It is preferable'that the cutsl?. be formed by sawing so as to provide a slight clearance at the edges of the tongue thereby preventing `bindin g orcatchingwhen the tongue is forced inwardly to engage Within the groove. Furthermore, the tongue is preferably of lessl ortions flared as'indil length than the slot formed by the cutting out thereof so as to leave an opening between the end of the tongue and the adjacent end of the slot through which may be inserted a tool for bending the tongue out in case it is desired to eect disassembliiig of the connecter With respect to the links.

In actual practice I have discovered that a connecting device constructed in this manner is highly efficient in its holding action and experiment has proved that very little strain comes upon the band or ring. bviously, assembling is very easily effected and no special toolsl are needed other than some sort of plierlike. device for forcingthe tongue into the groove. Another point of advantage is no particular difficulty will be experienced in effecting connection or disconnection in midair as the parts are few and easily connected. If a number of insulators be connected in a string by meansr of the connecting devices itis clear that they possesssuiiicient rigidity or limit movement of the links to such an extent that the entire string may be readily hoisted into place, excessive buckling being entirely avoided. The various 'features of advantage should be readily apparent to 'one skilled in theart. f 'l Y While I havevshown and described a preferred embodiment of the invention, it should be understood that the* disclosure ism'erely illustrative as'the right is reserved to make such changes or modifications as willy Widen thefield ofutility and increasethe adaptability of the invention'provided such variations constitute no 'departure from the salient features of the invention or the scope of the claims hereunto appended.

i `Having thus described the invention, I claim:`

l.' Connecting means for insulator suspension links having terminal heads, comprising counterpart members With mating recesses for the receptionof said heads, said members 'having each aperipheral groove therein, a

band encircling l'said members for holding them against separation, and means on the band'engageable Within one of the grooves to prevent movement of the band longitudinally `of said members, said'means consisting of a resilient tongue bendable to extend Within the groove.

2. Connecting means for insulator suspen sion links having partially spherical terminal heads,comprising counterpart castings With spaced recesses mating for the reception of the heads,- saidrecesses being partially spherical and of greater size than the heads to permitlimited play, vsaid castings eachfhaving a kgroove in its periphery, a band encirclingly engaged upon the castings and formed With a struckf'out tongue bendable to engage'within either of the grooves. 3. lConnecting,means for:V insulator suspension links having 'terminal heads, com# prising counterpart castings with recesses mating for the reception of the heads, said castings being formed with grooves in their peripheries mating to define a continuous groove extending circumferentially about the assembled members, and a band embracingly enga d upon the castings and'formed With a struc -out tongue extending circumferentially and engaging within said continuous groove to prevent longitudinal displacement of the band with respect to the castings.
