To all whom .it may/concern:
f Be it known that I, ORAL B. VALKER, a
1 citizen of the AUnited States, residing at Taylorville, inl the county ot' Christian and State of Illinois, have invented certain new and useful r-Improvements in Insulators, of which the following is a specification, ref erence being had therein to the accompanying drawing. I
This invention relates to 'telegraph or telephone poles, and has particular referi ence to the means for support-ing the cross arms upon said poles.
One ofthe objects of this `invent-ion is the production .of eiiicient means for firmly holding the cross-arms in engagementwith the poles so as tolprevent the same from sagging when a strain is placed thereon while stringing the wires.
Another object of this invention is the product-ion of eiiicient 'cross arms wherein the same consists of a plurality of transversely y extending members havingA their ends connected together whereby the two arms will be firmly held together.
`With these and other objects in view this invention consists of certain novel constructions, combinations, and arrangements of parts as willbe hereinafter fully described and claimed. y
In the drawings :e-Figure 1 is a front elevation of a. telegraph 'pole showing'one of the cross arms in section. Fig. 2 ,isa top plan view of the cross arms showing the telegraph pole in section. Fig. 3 is a side elevation of the telegraph pole showing the 'cross' arms in section. Fig. i is aside elevation of a telegraph pole partly in section showing the manner of connecting the cross arms to 40.
' telegraph pole showing saidpoles. Fig. 5 is aside elevation of the the cross arm in elevation having the insulators removed therefrom. Fig. 6 is an yenlarged sectional View showing the manner of connecting the insulator supp'ortto one of the cross, arms. -Fig. 7 is an enlarged sectional view ci one of the insulator supporting bolt-s showing the manner of connecting the bracing rods by means of` the common connecting nut.
Referring to the drawings by numerals 1 designates the telegraph pole which is provided'near the top thereof and upon each side with a transversely extending notch 2 within which are seated the cross arms 3. 'These cross arms 3 areformed preferably of hollow pipe sections carrying at their respective Specication of Letters Patent.
curing bolt 15 passes.
braced as illustrated in Fig. 3.
ends elbows 4- to which'y are connected the r. s Joining pipe sectlons '5 for forming a substantially cont-inuous'cross arm extending upon both sides of the\pole.
Insulator supporting bolts 6 are carried by the cross arms 3/'and are ,provided with enlarged heads Y for holding the insulators 8 firmly in engagement with the bolt 6. These bolts 6 are .also provided near their ends with a flared portion 8 which is adapted to rest upon the upper edge 'of-the' cross arms- 3 forlimiting the downward movement of said bolts through said cross arms. Alde-l pending stem 9 'is carried byu each bolt 6, which depending stem extends through the cross arms 3. A nut 10 is threaded upon the lower end of the depending stem 9 of each of the bolts 6 for firmly clamp-ing the bolts 6 in firm engagement with the cross arms. A Ynumber of these insulator supporting bolts 6 are used upon `each of the cross arms so as to accommodate a number of wires which may be attached thereto. Of course, the usual insulators 8 are formed ofthe common insulating material and may be of any desired form.
A pair ot' brace arms 11 are carried upon each side of the pole and these arpus 11 are provided with angularly disposed ends 12 which ends are engaged by a coupler nut 13, which coupler nut secures said angularly disposed end 12 to the under threaded end ot -one of the central insulating bolts as illustrated Ain Fig. 1. The brace arms 11 are provided with an eye 14 through which se- An arm 11 extends to each side of the pole as illustrated in Fig. 1, thereby constitutingr a substantially V- shaped brace, which brace may be readily detached by removing the nuts 13 from the threaded ends of the inner insulating bolts. A pair of arms 11 are secured upon both the back and front of the pole so that the arms upon each side of the post may be firmly Securing bolts 16 pass 'through the arms 3 for rmly holdin-g these arms in engagement with the pole. By, having a-plurality of these bolts 16 so passing through the arms, obvious that these bolts will also assist in preventing the arms Vfrom sagging upon their sides, as well as the brace arms 11 previously described. It will be `further o bvious that vthe crpss arms may also be readily removed from the pole by detaching the different sections, and provided only one of the it will be y Patented July 16, 1912.,
