latented Aug. 6,1912.

To all whom it may 001mm:

construct a hanger which includes a Eeit known that I, ALBERT Sonar-Btu, citizen of the United States, residing at Chicage, in the county of Cook .and State of lillinois, have invented a certain new and useful Improvement in Hangers for Electrical Apparatus, :o-f which the follow in is a full, clear, concise, and exact dQSCIIPtIOII,

reference being had drawings, forming a tion. 1

My invention relates to hangers for electrical apparatus whereby such apparatus may be suspended and properly insulated.

It is one of the objects of my invention to v pet coated insulator normally relieved of the to the accompanying weight of the electrical apparatus, such as an electric lamp, but adapted to take part in 1 the support of such apparatus in the event of breakage of the means that normally supports the apparatus. In practising this feature of my invention, I desir-- ably provide a pocket or recess in the up: per portion of the aforesaid insulatorand pass a supporting element through said pocket and through the metal cap in which the said insulator is preferably disposed.

'nThis supporting element is desirably of composite formation, one portion thereof constituting a pin passing through the cap ofthe insulator and another portion thereof being desirably in the form of a grooved disk having a bore through which said pin passes. A metal member engages the aforesaid disk by surrounding or partially surrounding the same,

adapted to carry the lamp or other device.

The disk is also of insulatingmaterial, said disk and insulator bein desirably, though not necessarily, made porcelain. There is sufficient clearance between the walls of the .pocket of the insulator and themetal parts surrounding or partially surrounding the disk whereby said insulator is normally relieved of weight which is borne by the insulating disk or .block be broken, the

metal member surrounding :the same will be engaged by "the walls of the pocketor part of this specificathis member carrying an' additionalstructure,=such as a hook, that is",

chamber of the insulator, which walls will then support the metal member. independe ently of the said disk or block.

Another feature of my invention resides which is bent at its mid portion to constitute a substantially circular loop which'incloses the aforesaid disk, the ends of the loop being bolted together and there secured to somesuitable device, as a hook, whereby the lampor other structure may be support- 'ed. I secure two arms to the folded metal strip by means of a bolt passing through adjacent ends-0f the arms, between which the metal strip is disposed, 'andpreferably through said metal strip also. The inner ends of the arms are preferably of 'L-shape in plan View, the short stem of the L of one arm being opposite the short stem of the L of the other arm, the short stems of the Us having butt engagement with the long stems of the Us, wherebya rectangular channel is *formed between the adjacent ends of the armsof-a size suited to the metal strip pass- .ing between the ends of the arms. The

preferably steel,

outer ends of the arms carry suitable insulators for the line wires.

I will explain my invention more fully by reference .to the accompanying drawing, showin the preferred embodiment thereof, in whic c Figure .1 is a sectional View, partiallyin elevation, of a device gonstructed in accordance with the preferred embodiment of the invention. Fig. 2 is a sectional view of the upper portion of the structure shown imFig.

The pettiooated insulator ais supported thrbughout the different by a pin 'b passing through theimetal cap 0 which is provided with-any suitable formation, such as the eye d, whereby the cap and the parts it supports may be suitably susinto which a disk of insulating material e may he slipped, this disk having a bore through which thepin b may he slipped. A supporting member f, preferably in the form of strip metal, desirably substantially completely surrounds the disk e and extends through a channel in; the insulator a lying below the pin 6- The member 7 supports some suitable means, such as the hook g from which the arclamp or other appa-' ratus may be suspended, the attachment of this hook, in accordance with the preferred I embodiment of the invention, being hereinafter explained.

In assembling the parts, the free ends of I the metal strip j (which are then free of the devices 9 and the other structural parts illustrated at the bottom of the element f) are temporarily clamped together, there being normally preferably a tendency for these free ends to swing apart, the disk a first having been surrounded by the metal strip, whereafter the free ends of the metal strip are passed downwardly through the insulator (1 until the bore in the diskv e is brought into alinement with the holes in the caps that are to receive the pin 6, whereupon the pin 6 is passed through the cap 0., .the insulator a andthe disk'e, so that the parts are thereupon secured together. The ends of the pin 6 may be elevated orupset 5 so as to prevent said pin from moving longitudinally after it is in place. The arrange- 450 there inent of the parts is such that the insulator a is normally relieved of any of the load which the device is designed to support,

normally being sufficient clearance between the supporting element 1 and the insulator a to cause all of the load to be carpurpose of excluding moisture ried by the element f, the disk 6, the pin 6 and the cap 0. After the parts have been assembled as has, been stated, insulating wax, such as ozocerite, is poured through the cap-at the openings it, so as to fill the spaces intervening between the cap '0 and the insulator a and intervening between the insulator a and the elements 6 and f for the rom the parts within the cap. Byproviding clearance between the disk 6 and the insulator (1 around said disk, the wax may find its way well about the parts 6 and f so as more thoroughly to protect the parts within the ca against the entrance. of moisture, which would be liable to cause a path ofleakage for currents.

If the element 6 should become broken, for example, as a result of a lightning discharge, the circular portion of the element f, being larger than'the passage in the insu lator a through which the element f is, passed downwardly, said element a is ennoeaais I abled 'to s pport the suspended loadupon the breakage of the disk e.

The element f constitutes a vertical stem from which arms 2' z laterally extend, the outer ends of these arms supporting suit able insulators k of any preferred or suitable type, for'holdingline wires. The inher ends of the armsi are-preferably each L-shaped in plan view and are similarly formed, so that when a pair of the arms are assembled in reversed relation, the stems of the \L formations are engaged with each other, the shorter stems with the longer, so

as to form a rectangular vertical channel through which the element f passes, a single bolt Z being sufficient, when passed through the element f and the irmer ends of the arms 5, to hold said arms and the element or stem f in fixed relation. The bolt Z also serves to clamp the parallel stri portions constituting the element f toget er, so as to relieve the insulator a of the stress it would otherwise be subject to if the insu lator were relied upon to compress these strip portions together. The element f may, if desired, be extended below the arms 2', in which caseanother bolt'm may be employed for further'clamping the strip portions of the element j together, this bolt m, in the embodiment of the invention shown, passing through the hook-structure g, whose purpose has been stated.

While T have herein shown and particularly describedthe preferred embodiment of my invention, I do not wish to be limited to the precise construction shown, as changes may readily be made without departing from the spirit of my invention.

Having thus described my invention, I claim as new and desire to secure by Let ters Patent the following 1. A hanger including an insulator hava depending petticoat and .a perforation substanti lly 'co-axial: with said ,petticoat, said per oration being enlarged into a chamberat the upper e113 of the insulator; a cap covering the chamb red end of the insulator; a substantially horizontal pin passing through said cap and insulator; an insulating block upon said pin within said chamber-3' and mally carried by said insulating'block, and being larger where it engages the block than the unenlarged portion of the perforation above which unenlarged perforation portion said block is disposed, whereby the supporting element is held upon breakage of the said block;
