Specification of Letters Patent. P

Application filed June 8, 1914. Serial l lo, 843,717.

To all whom it may concern:

Be it known that I, RALPH C. Boozer, a citizen of the United States, residing at Chicago, in the county of Cool; and State of Illinois, have invented certain new, and useful Improvements in Insulator-Supports, of which the following is a specification.

This invention relates to improvements in insulator supports.

The invention is adapted more particularly for use in connection with molded insulators made of glass, porcelain or the like having a tapered threaded opening for mounting. It is practically impossible in manufacturing molded insulators of this type to secure exact uniformity in the threaded bores due to the irregular shrink age of the material during cooling.

One of the objects of my invention is to provide a support for insulators of this character which will adapt itself to irregularities in the tapered threaded bore without subjecting the insulator to unnecessary strain.

Another object of my invention is to provide a support of rugged, simple and inexpensive construction adapted to be secured to a channel bar by a single connecting member.

Other and further objects of my invention will be apparent to those skilled in the art from a consideration of the following de' scription and drawings, wherein:

Figure 1 is a vertical, central, sectional View through an insulator and support. Fig. 2 is a vertical central, sectional view through an insulator and support, taken on a plane at right angles to that upon which Fig. l is taken. Fig. 3 is a top elevation of my improved insulator support, and Fig. 4: is a transverse, sectional view on the line of Fig. 1, with the insulator detached.

Referring to the drawings the numeral 10 indicates the body part of a glass insulator of a well known type having at its lower end the outwardly flanged petticoat l1 and an axial tapering threaded bore 12.

The supporting bar 13 is of the usual channel shape, as is customarily employed threads of the insulator bore 12 is so mounted upon the support as to provide dametric slot 18 separating the two halves let and 15.

As the insulator supporting shell i vanized to prevent iii-sting of the 111. have cut away a circular dpening 17 upper end of the shell to permit of cleu the interior of the shell after the galvani' in process. This permits the flakes such as ma l be formed within the shell during t v vanizing process to readilv'slianu through the end. V w

The lower end of the semilinurical shell member Il-l below the is formed inwardly resulting in an arch like ortion 18-, the extreme lower end fitting a ainst the side of the bar 13 and having itsedg es formed over into lips 19 which final-res old e contact with the outer sides of the channel bar 18. The other shell member 15 its lower end is 1 at the open side of the channel bar and at its lower end carries a tab lient right angles to the axis of the cvlindrioal. shell making a tight fit within the channel of the bar 13. A rivet 23 takes through the welo of the channel bar and the lower ends 18 and 2O o f the semi-oylindrical shell members.

The lips l9-2l together with the tab 22 and rivet :23 rigidly connect the semi-cylindrical shell members Liand 15 with the no per end of the channel bar 13 providingn sturdy, eliioient connection andat the same time permitting the upoer free ends of the semi-cylindrical shell 1 .nhers to move radially inwardly or outwardly in order to adapt themselves to variations in the threaded bore of the insulator.

lVhereas I have illustrated and described a single embodiment of my invention, it is obvious that various changes may he made in theconstruction without departing from the spirit and scope thereof,

Having described my invention, what I claim 1s:-

1. An insulator support, comprising a si1 )porting channel shaped. post, two iridependent semi-cylindrical threaded sections, the lower ends of the said sections being formed inwardly to contact with opposite sides of the channel post, lips formed. on the edges of the inwardly extending ends of the said sections, and means for rigidly connecting the lower ends of said sections in spaced relation to an end of the supporting post, the upper ends of the said sections lee-- ing spaced away from each other, substantially as and for the purpose setforth.

2. An lnsulator support, COIDPIlSlIlg a formed inwardly to contact with opposite sides of the channel post, lips formed on the edges of the inwardly extending ends of the said sections, atah formed on the lower end one of the said sections and extending into the channel of the said post and means for rigidly connecting the lower ends of said sections in spaced relation to an end of the supporting post, the upper ends of the said sections being spaced away from each other, substantially as and for the purpose set forth.

3. An insulator support, comprising a supporting channel shaped post, two indewardly extending ends of the said sections,

a tab formed on the lpwerend of one of the said sections and extending into the channel of the said post and means for rigidly connectingthe lowerends of said sections in spaced relation to an end of the supporting post, the upper ends of the said sections being spaced away from each other, substantially, asand for the purpose set forth. 4 v

In testimony whereof I hereunto set my hand in the presence of two subscribing witnesses.
