.T all whom it may concern 7 Be it knownthat 1, JOHN NLVUPTONLZL citizen of the United states residing at Louisville, in the county of Jefferson and State of Kentucky,- have invented certain new and useful Improvements in a PullAttachment for Electric-Switch Key Sockets; and I do hereby declare the. following to be a full, clear, and exact-description of the- 10. invention, such as will enable'ot-hers skilled in the art to which it appertainstomake and use the same.

Key operated switch sockets asusuallyi provided for electric lights and electricplug in fixtures generally are not always conven- 1 ient of operation or readilyaccessible, hence the desirability of providing a pull attachment.

The present inventionrelates to means;

capable of being readily applied to the key of any ordinary switch'keysocket whereby,

to convert the same into a pull switch socket, the attachmentbeing such as to be repeatedly usedwwithydifferent sockets so that when 25.one socketbeco'mes disabled from any cause the attachment mayfbe removed therefrom a dead center. Another important feature resides inthe peculiar formation of ithe key lever which issectional, the key being clamped between the sections. A further-i feature is the pull connection. which inarms as indicated most clearlyin Figure 1 cludes two elements, both passingthrough the said guide and each attached to. an end of the key lever and having a grip at its a. lower end, one of the grips having sliding 40 engagement with--.one of the pull elements which projects therebelpw some distance to insure positive distinction therebetween and i whereby displacement of the'lever as a whole the avoidance of confusion in the dark.

Other objects and advantages will be apparent and suggest themselves as the nature of the invention is understood.

While the drawings illustrate an embodiment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the form, proportion and minor details of construction may be resorted to invention;

'Referring to the accompanying'drawings formlng a par-tot the, specificat on, Figure 1 1s anelevation of an attachment applied to the key, of. aiswitch socket ,f the latter being indicatedby dotted lines, Figure 2 18: an edge, view" of theparts' shownin Figure'l. I

The numeral l kdesignates a key opera-ted without departing from thefnature 'of the i switchsocket such as generally provided for electric light and electric :fixtures to be' plugged in The switch 'operatingkeyiis, v designated b'y'xthe numeral 2. The present. invent on is designedtobe appliedtouthe' keys of sockets of the type hereinindicated which are of similar i or like formation;- each The attachment comprises a, levelf w hich, is provided in similar or like sectionsf between which the key 2 isclamped,-1the sections oryparts. projecting in opposite ,directions as clearly indicated in Figure l. a The key lever comprises the'sec'tions or aromas,

having.an.,offsta11cling flange 4 at, its' inner endand an openin 5 at itsouter end "The? flanges Ahave an o lique arrangementl w-i-th reference to the length ofthe. respective and openings at opposite ends in registering position to receive screws or fastenings fii 60 whereby the arms orsectionsBare' clamped against opposite sides of the key 2. The fa'stenings Genga'ge the head ofth'e key 2 upon opposite sides of the contracted portion 1 is preventec i guide 4 preferably consists of an eye which flares on the side facing the key 2. The guide 7 is carried by the socket 1 and may be attached thereto in anymanner accord ing to the application of the invention. In i I the preferred construction the guide 7 is provided with a spring clamp 8 which is adapted to engage the socket 1 and retain the guide in operative position. The spring clamp 8 embraces more than one half of the socket l and is prevented from longitudinal displacement thereon by engaging the usual bead-9 formed near the open or receiving end of the socket. The inner side of the clamp 8 is made hollow as indicated most clearly in Figure 4: so as to receive the bead 9.

The pull connection cooperating with the key lever comprises two elements 10 and 11 which pass through the guide 7 and are connected at their upper ends to opposite ends of the key lever preferably by means of links 12 engaging the openings 5 in the outer ends of the arms 3. The pull elements l0 and 11 are preferably flexible so as to operate through the guide 7 by a running action and provide for the change of angle of the portion above the guide 7 and between it and opposite'ends of the key lever. The pull elements 10 and 11 may consist of cords, wires, chains or other like flexible connecting means. 13 is attached to the lower end of the pull element 11 and slidingly engages the pull element 10 which preferably passes therethrough. The pull element 10 extends some distance below the grip 13 and is provided at its lower end with a grip 14'. The grips 13 and 14 may be of any construction or of contrasting color or may bear indicia to designate when the current is off or on. "When the grip 13 is drawn downward the switch key 2 is operated to turn off the current. l/Vhen the grip 14 is drawn downward the switch key 2 is operated to turn on the current. The relative disposition of the grip the one above the other precludes confusion in their operation in the dark and by having the grip in line their relative position may be easily determined by passing the hand along the pull connection. The pull elements 10 and 11 by reason of their relative disposition are not liable to become entangled and the grip may be readily selected by reason of their disposition and easily operated to turn on'or off the current. The disposition of the guide 7 precludes movement of the lever past the center or stopping on a dead center so that it A grip element may be readily operated by pulling upon the proper grip which is in operable position.

Having thus described the invention, what I claim is r v a 1. A pull attachment for electric switch key sockets, the same comprising a sectional lever consisting of two sections adapted to be positioned one at each side of the switch key, each of said sections having a flange at its inner end adapted to engage a side of the key, adjustable fastenings connecting the flange of one section to the flange of the other section and adapted to clamp the sections to the key, said adjustable fastening providing means whereby the attachment may be applied to keys of ditferent shapes, and pull elements having connection with the outer ends of the lever.

2. A pull attachment for electric switch key sockets, the same comprising a sectional lever consisting of two sections adapted to be positioned one at each side of the switch key, each of said-sections having a flange at its inner end adapted to engage a side of the key, adjustable fastenings connecting the flange of one section to the flange of the other section and adapted to clamp the sections to the key, said adjustable fastening providing means whereby the attachment may be applied to keys of different shapes, said adjustable fastening means adapted to pass on opposite sides ofthe key stem and engage the inner edge of the key whereby to prevent displacement of the lever from the key, and pull elements having connection with the outer end of the lever.

3. A pull attachment for electric switch key sockets, the same 'comprising'a lever secured to the key and projecting inopposite directions therefrom, pull elements having connection with opposite ends of the lever, and a guide positioned on the socket and receiving the pull elements and so 311'". ranged to prevent movement oi the key past center or stopping with both ends on dead center, when either of the pull elements is pulled.

In testimony whereof I afiix my signature in presence of two witnesses.
