ATTACHMENT FOR ELECTRIC-LIGHT SWITCHES.

Application filed June 25, 192i; Serial No. 201,360.

This invention relates to attachments for electric switches and more 1 particularly to removable extensions for th'ethimbleof a universal, chain type electric light switch.

The principal objectof the invention isthe' provision ot a simple and economical device. adapted to be quickl and easily applied to P ot ct ng h 1e p a ee livg v i switch 'o'fthe aforesaid character and to,

serve as an extended-lever otsuch length" that a o jor h ns ce edia the u r endof the lever will hang; vertically with out. contacting with the light globe. I

The so-called universal j type of chain switch having an outwardly extending p,- a ve hi le act a b r i s' r tilting the thimble; or by, pulling a. connected cord .or chain in' an desired direction iswell known and has een provided in large and increasing quantities as a convenient electric lighting switch for ceiling lights. In the usual t pe of ceiling fixture, however, the light globe is ofsuch large diameter that its periphery projects horizontally beond the vertical p ane of the switch thimtile, so that the cord or chain depending from the thimble hangs angularly in contact with at least one'edge of the globe.

Consequently, when the cord is pulled to actuate the switch, it is drawn across the globe edge and, if the globe is of the usual chain supported swinging type, causes the globe to swing pendulum-like, thus creatmg a flickering effect of the difiused hght and frequently so loosening the globe fasteni s that the globe falls to the floor. In o i fier to obviate these disadvantages, I have devised an attachment which will permit the pull cord to han freely at such distance from the edge 0 the light globe that objectionable contact between the cord and globe, when the cord is pulled, is avoided.

A recommended embodiment of the invention is illustrated in the accompanying drawings, in which: i

Fig. 1 is a side elevation of a ceiling light fixture showing the improved device attached to the switch in operative position;

Fig. 2 is an enlarged section on the line 2-2 of Fig. 1;

Fig. 3 is a plan view, partly in section, of the attachment; and

Fig. 4 is an enlarged section through the device on the line 4-4 of Fig. 1.

Fig. 1 shows a conventional type of stationary ceiling fixture having a base 5, a

globex support 6 and a glass globe 7. The

disposition of the usual form of universal switch 8 ha ving the operative thimble 9 pro ect ng laterally from the base 5 and provlded with la pull chain 10 is best shown in Fig, .2. It will be understood that the switch may be operated either by a direct outward pullxupon the thimble or til ting the thimble in any direction with respectto its normal axis.

Attachedto the thimble 9 is a rifetalrod or" lever havi'g a tubular end 11 fitting over-the thimble. The outwardly extending portion 12 of the lever maybe of any de sired size or shape, is" preferably ofre' duce'd size anasemi-mbunr, as shown, to"

lessen its weight. A ire-1e 13 maybe provided' at the outer end oftlie device for the convenient attachment of a cord14, for-e25 ample, as shown in ig. 4. The length of the lever is such that it overhangs the light globe so that the cord hangs vertically at an appreciable distance from the outermost edge 15 of the globe. I

The lever is preferably secured upon the thimble 9 by the thimble chain 10 which is retracted slightly and slipped into'a slot 16 provided in the tubular socket portion '11. The beaded chain may then be cut ofl' so that its end head 17 engages the outer surface of the tubular socket at the inner end of the slot, thereby holding the attachment in position by reason of the chain tension.

An attachment constructed as above described simplifies the operation of the switch, for a relatively slight pull, either downward or outward from the globe, will actuate the thimble 9 without causing the cord 14 to strike the globe. The device may be made at reasonable cost of. such size that it will fit any usual type of switch thimble and will have suflicient overhang above the light globe and may be attached and removed by simple hand operations. It will be understood, however, thatdetails of construction may be varied without departing from the spirit of this invention, as defined in the following claims.

I claim:

1. An attachment for electric light fixtures of the ceiling type and having a projecting operative switch thimble of universal movement, consisting of a rigid, elongate member having a socket portion removably secured to the switch thimble, and a pull cord attached to the outer end of said over said thimble and being removably secured thereto, and a pull cord attached to the outer end of said lever, said cord hanging perpendicularly at a distance from the periphery of the light globe, whereby the cord will not contact with the globe when pulled downwardly.

3. An attachment for electric light fixtures of the ceiling type and having a projeeting operative switch thimble of universal movement, consisting of a rigid, metal lever overhanging the light globe and havin a tubular socket portion fitting over said thimble, said tubular portion having a longitudinal slot extending toward its outer end and the thimble having a pull chain engaging said slot under tension, thereby securing the socket upon the thimble, and 2.

pull cord attached to the outer end of said lever, said pull cord hanging perpendicularly at a distance from the periphery of the light globe, whereby the cord will not contact with the globe when pulled downwardly. y

l. An attachment for electric light lixtures of the ceiling type and having a projecting operative switch thimble of universal movement, consisting of a rigid metal lever overhanging the light globe said lever comprising a tubular socket port1on,longer than the projecting thimble, fitting over said thimble, and a semi-tubular outer portion said tubular portion having a longitudinal slot extending toward its outer end and the thimble having a pull chain engaging said slot under tension, thereby securing the socket upon the thimble, and a pull cord attached to the outer end of said lever, said pull cord hanging perpendicularly at a distance from the periphery of the light globe, whereby the cord will not contact with the globe when pulled downwardly.

Signed by me at Boston, Massachusetts, this 23rd day of June, 1927.
