INSULATOR MOUNTING.
Application led June 13, 1919. Serial No. 304,022.
To all whom it may concern:
Be it known that I, EDsoN O. SESSIONS, a citizen of the United States, residing at Chicago, inthe county of Cook and State of Illinois, have invented a certain new and useful Improvement in Insulator Mountings, of which the following is a specification.
My invention relates to an improved form of insulator mounting by which several insulators may be secured together in a simple manner and at the same time positively, as for example, where it is desired to make use of a plurality of insulators to constitute a combined insulating unit or I where it is desired to secure mounting bases to insulators, since my improved construction is readily applicable to either purpose. It is an object of my invention to produce a construction of the kind referred to such that the parts engaging the insulators may readily adapt themselves to any irregularities in the surface of the insulators incident to their manufacture, and-yet firmly engage the insulators so that by the use of the device an insulator may be secured firmly to an adjacent insulator or to amounting plate as desired. Another object of my invention is to provide an insulator mounting of the kind referred to, which shall be easily and inexpensively manufactured.
My invention will best be understood by reference to the accompanying drawings, showing preferred embodiments thereof in which Fig. 1 shows one form of the mounting devices in sectional view connecting iwo ad* jacent insulators.
Fig. 2 shows in a developed plan view the connecting device employed in Fig. 1.
Fig. 3 illustrates the device shown in Fig. 2, bent into circular conformation which is ythe position it assumes when placed on an insulator.
Fig. 4 shows in a view similar to Fig. 1 a modified construction of the mounting device.
Fig. 5 shows in a view similar to Fig. 3 one of the annular tubes employed as a part of the device shown in Fig. 4.
Fig. shown in Fig.7shows in side elevation aconnecting tube employed as a part of the device shown r in Fig..4.
6 is a sectional view of the tube, Fig. 5, taken along the line 6-6."
Fig. 8 shows in a view similar to Fig. 4, a modified construction of the device shown in Fig.` 4, to adapt said device to the securing of an insulator to a mounting plate, instead of connecting two insulators together.
Fig. 9 -shows in a view similar to Fig. 4 a second modified form of mounting device, the difference being that the annular tubes shown in Fig. 4 are replaced by ring sections of solid material held in place by setcrgews :extending through the connecting Fig. 10 shows in a view similar to Fig. 8 the connecting devices of Fig. 9 modified to secure an insulator to a mounting plate instead of connecting two insulators together, as shown in Fig. 9.
Fig. 11 shows in a view similar to Fig. 9 afurther modified form of my mounting devlce for securing a mounting plate to an insulator by means of a short tube which is forced into an engaging position by compressing said tube.
Fig. 12 shows in said elevation a connecting tube employed in the construction shown in Fig. 11 before said tube is compressed.
Fig. 13 shows in cross section the mounting plate shown in Fig. 11 before being secured to the insulator by the connecting tube shown in Fig. 12.
Similar numerals refer to Asimilar parts throughout the several views.
In the construction shown in Figs. 1, 2 and 3, the connecting devices employed consistof a strip of sheet metal 15, which as shown in Fig. 2 has its opposite longitudinal edges rolled over upon the body portion of the strip to lorm edge beads 16, which may be elliptical or circular in cross section before the device is put in place on the insulator or insulators, these beads extending nearly the entire lengthof the strip 15, and being cut away at one end of the strip as indicated at 17, so that when the strip is formed to surround the bosses or of the insulators 19 to be connected together by the device, the end 17 of the strip 15 overlaps the other end of the strip in which position it is securely held with the beads 16 in the grooves of the insulators adjacent 1 the heads 18 in slightly compressed condition, by welding electrically or otherwise connecting the end 17 to the other end of the strip l5.
As a result of this construction the formed heads 18 10 CTI strip having its ends secured together as described, securely engages the head of each insulator and the shape of the beads 16 and the spring action of the sheet meta-l of which the strip 15 is formed, permit the beads to yield and conform to the exact shape of the surfaces of the insulators engaged by them, whether said engaged surfaces are regular or irregular.
In this manner a series of insulators may be secured together mechanically in a rigid and efiicient manner for whatever purpose desired, as for example, for constructing a post insulator consisting ofa pluralityv of individual insulators, for forming a connected series of suspension insulators, or for any other purpose for which it is desired to connect the plurality of insulators to form a single insulating unit. lt will be observed that one of the beads 16 may be omitted if desired, and replaced by a mounting plate, secured in any desired manner to the strip 15 either before or after placing the strip on an insulator, so that by this modified construction any `desired devices may be securely held in place by the mountingv plate on the insulator. This modified construction is not shown in the drawings as the relation between the mounting plate and the strip 15 is of the same nature as that shown and described inconnection with Fig. 8 below.
In the construction shown in Fig. 4 the strip 15 is tubular in form and preferably without a longitudinal joint or seam, being of just the right internal diameter to compress the annular tubes 16a in place in the grooves adjacent to the heads of the insulators 19, when the parts are placed in the connecting position shown in Fig. 4. Each annular tube 16a is formed of a cross section as indicated in Fig. 6, which may be circular or elliptical, and when the connecting tube 15a is forced to the position shown in Fig. 4, over the annular tubes 16a. the latter are flattened somewhat and. forced positively into engagement with the adjacent surfaces of the insulation 19, whether said surfaces are regular or irregular. The connecting tube 15a as shown in Fig. 7 is provided along each end with a series of apertures 20, extending through it, which apertures are in line with the annular tubes 16l when the mounting devices are in connecting position as shown in Fig. 4, and the parts are preferably held in connecting position by electrically welding them together through the apertures20, or other suitable means.
In the modified construction shown in Fig. 8. the tube 1bb is somewhat shorter than the tube 15 but of the same general construction, and when in place on the insulator 19h, is secured to the annular tube 16b in the manner above described. for the construction shown in Fig. 4. In this construction'the second annular tube 16a is replaced by a mounting plate 21, which may be secured to the tube 15b in any suitable manner, as by welding or brazing, either before or after the tube lbis placed upon the insulator 19,
or if preferred, the mounting plate v21 may be an integral part of the tube 15b.
In the modified construction shown in Fig. 9, the same general result is secured as with the construction of Fig. L1, but in this case the connecting tube 15a is replaced by a connecting tube 15, provided at either end with a plurality of set-screws 22 for engaging the ring sections 16, which may be of metal and of a semi-circular or semi-elliptical cross section to lit the grooves adjacent the heads of the insulator 19C, the outer snrfaces of the ring sections 16 being of conical conformation to prevent the set-screws slipping from the ring section when forces are applied to the insulators tending to sepa `ate them. The ring sections may be made in halves or other parts of circles to facilitate placing the sections in positionv in the insulator. In the modified construction shown in Fig. 10 the connecting tube 15d is similar to the connecting tube 15c shown in Fig. 9, and provided with a series of set-screws 22n for securing the connecting tube to an insulator in the saine manner described in connection with Fig. 9, and in lthis modified construction the other seriesof set-screws and the other ring sections employed in Fie. 9 are replaced by a mounting plate 23 which, as indicated, may be integral with the connecting ring 15d, so that any desired devices may be supported upon the mounting plate,
and secured to the supporting insulator not of said tube is made'in expanded conforma-j tion, so that the inturned flange 27 may be slipped over the head of theinsulator and over the ring sections 16, and when the connecting tube 1s in a position bringing the flange 24 firmly into engagement with the edge of the. mounting plate4 25. the expanded portion of the connecting1 tube is compressed by suitable tools, bringing the cut or slit 26 together. in which position it may be held by welding electrically, by brazing or any equivalent means.
If dcsired, th'e mounting plate 25 may be constructed as lshown in Fig. 13, so that its edge portion 28 extends away from the in ner surface ofthemounting. plate, so-that said edg'eportion is s rung into the plane ofI the inner surface -o the mounting plate, when the connecti tube 15 is forced to Ithe position shown m Fig. 11y to engage the rin sections 16, For this arrangement the lspring action for the edge portion of vthe mounting plate materially assists inri idly securing .the mounting plate to the insu ator i tunity for slight irre larities'in the dimenl v plate toman insulator, and that ifi-either case,
in desirable position and allowsan opporsions and conformatlonof the head of the insulator 19e without interfering with the effectiveness of the mounting device.
From the above it will a i pear that by my invention I have provide a mounting device which may -be cheaply constructed',
which may be employed tosecure a plurality i of insulator units together to form a composlte lnsulator, or to secure a mounting the sire arts are ositivelyheld together in de'- relation y the mounting device with out danger of injury to the insulator, andV -without the use of cement.
Vhile 'I have shown my invention in the particular embodimentsv above described, I do not, however, limit-myself to these exact constructions, as'I may employ equivalents thereof, known to the art at the time of the filing of this lapplication without departing from the scope of the appended claims.
