To all whom it may com; Be it known that I, I

ALTER, a resid or nd useto be a full, clear, and exact description.

This invention relates to pull chains or that type of electric socke monly known as pull chain sockets its principal object is to provide a he pendant which may be do chain without the intermed 15 any separate connection. between the j" dant and chain. Luminous pendants s are commonly con hollow bodies coated on. the.v faces with a luminous composition, whe they are made visible in the dark, and a metallic collar or connect tached to the pendant, which coliar in turn to the chain. This makes a con partlvely expensive constructior; and a. very thin metal is used for the collar there the pull pull chai is attached ts which are com-- rectly attached to or is more or less danger of the collar hell :1

torn from the chain in 11 Another object is to provide lunnrn pendant which may be readily attached to the common and well known chain to take the place of the or body with which said chains Vvith these objects in view, this equipped.

of pull common ball usually inventlon consists in the several novel features hereinafter fully'set forth and c The invention is clearly illustra accompanying drawing, in whicl Fig. l is a side elevation of a it pull chain of common form, wit

line 2-2 of Fig. tical section taken 4-4t of Fig. 2.

character 5 designates a \U o. a lumi nous pendant, embodying a simple form of the present invention, applied thereto; Fig. 2 is a central longitudinal section taken on pull ch men and well known form, such a most universal use on electric light socr is commonly known as pull As 1S well understood, by t of com chain sockets hose lai in e d. in the l l l'ltilll: (l l:

1; Fig. 3 is a central veron line 3-3 ott ll! Fig. 4 is a horizontal section tailed the art to which this invention pertains these pull chains are made up low thin shelled balls or having diametrically opp osite holes b of small holspherlcal ob a re u n Serial No. 527,594.

which extend hort stems 7, usually formed of wire. Each stem 7 extends from the hole one i to the hole of an adjacentone and has h 8 formed on its ends, which are contained in the balls.

'3 a uendant 9 is n'xade oi a hollow open s body, and the internal face thereof is ccited with a luminous substance 10, as is well understood, whereby it is made visible in the dark. Any suitable shape may be given the pendant, and this is immaterial so as this invention is concerned. The diameter of the hollow space is slightly greater than that of the balls 6, to permit the pull chain to pass freely therethrough. one end oi the hollow body is contracted to m a restricted opening 11 ot' approxi tely the same diameter as the diameter rails. The low r 410st ball 6 is fiatmcrease its diameter in one direc :eby said lowermost hall may enunderside 12 of the contracted 0 thereby prevent the pendant 'lled oil the chain when in use. the common pull chain knob endant, embodying the presthe ('l'ltllll is cut oil immcdi a ball or grip, and the end of d through the restricted l oi the peinlant 9, and passed out the oher end thereof. The thin nd nost ball 6 is then flattened with pinchers, or by striking it a blow iammer or other tool, to thereby dougate it along a line at right angles to length of the chain. The head 8 0t e stem 7, which is contained in the elongmlied hall (3 prevents the shell of the ball 6 our being flattened down into athin piece, and forms a solid core, as it were, about which the shell is pressed down. The result is that the upper edge portion which bears grainst the underside of the contracted upaer end oi' the luminous pendant, takes a *nded shape, which is not liable to crack he glass pendant, when the latter is pulled coon.

Moreovm'. the pull chain and luminous pen lent body are thereby directly connected. and other or additional members for tonne-sting them are disposed with. The dc vice is therefore it expensi e to construct, and because the pen. 9 can be attached to the chain by any one witlmut the aid of tool other than pair of ply-ere or a hamm or the like, for flattehi the endor grip w: 1: int. ion, 5' :llime til 1 chain in most ball, it is more saleable and finds a ready market.

More or less variation of the exact details of construction is possible without departing from the spirit of this invention; I desire, therefore, not to limit myself to the exact form of the construction shown and described, but intend, in the following claims, to point out all of the invention disclosed herein.

I claim as new and desire to secure by Letters Patent: I

1. A pull chain, composed of hollow, thin shelled bodies, connected by headed stems, and a hollow open ended luminous pendant having a contracted portion containing an opening of substantially the same diameter that of the hollow whereby the latter may pass bodies of the chain, therethrough,

the endniost hollow body being elongated transversely of the length .01 the chain, to form a rounded shoulder engaging with the underside of said contracted portion of the pendant.

2. pull chain, composed of hollow, thin shelled bodies, connected by headed stems, and a hollow open ended luminous glass pendant, having a contracted end portion containing an opening of substantially the same diameter as that of the hollow bodies of the chain, whereby the latter may pass freely therethrough, the endinost hollow body being somewhat flattened down upon the head of its connecting stem to form a rounded elongated shoulder, which engages with the underside of said contracted end portion of the pendant.
