This invention relates to means" for removing and replacing electric light "bulbs which are inaccessible from the floor, except through means of a ladder or'the like, the general object of the invention being to provide a supporting member of considerable length and having a' vacuum cup .at. its up- I per end for holding a bulb, ,withvmeans for imparting movement to the cup from a point 7 adjacent the lower end of the supporting means so that the electric light will be unscrewed from its socket or screwed therein while being held b the cup.

This invention a so consists in certain other features of construction'and in the combina-.

.tion and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifi ,cally pointed out-in the appended claims.

erence will be had'to the accompanying drawings wherein like characters: denote like or, corresponding parts throughout the several of the strip is provided with anumber of holes 4 through any one of which the bolt can be passed so that the bracket can be 5 is fastened to the top part of the strip by the bolt 6 and a sectional shaft 7 is rotatably supported in these brackets. The upper end of the shaft passes entirely through the bracket 5 and the lower end extends together by the c0uplings8 so that the length wheel 9 is journaled on an extended part of said gear;

In describing the invention in detail, ref- Figure 4- is a view ofthe'structure inter-.

of the strip by the bolt 8 and this portion A adjusted lengthwise on the strip. A bracket through the top part of the bracket 2. The. from the Shaft i sections of the shaft are detachably connected the bolt 3 a is connecte d to- I A- pinion 11 is fastened'to the lower end it ofthe shaft 7 and meshes with the gear- 9 so that when the gear :9- is rotated,- the shaft. with alsobe rotate'd. The upper end ofthe shaft Z- carries a chuck 12 which acts to hold a vacuum cup 13, said chuck being illustrated asof a standard commercial-type and therefore tapei' -ed; and:subject to movement lon'gie tudinally "of its; mainaxis to operative position; t: A toothed wheel 14:is rotatably sup? ported by theinppersbracket 5 -as'=-shfown at 1 5, .and at pinion 161' on. the upperizpa-rt 'ofthe shaft 7. meshesfavith ithe lto-othed wheel isd thatthe rotary movement-of the. shaft is i-"m -f parted t'ethe wheel 14.

The shaft carries chuck 18 for holding" a. vacuum .c1ipfi19. By providingthe-chucks for-holding the vaouum :c'ups, different ,siz'es .of'icu'ps can bea placedin the chucks in accords ancewith'r the size 'of the electric bulbs to; be: handled; =1 EW'henrthe ;.device:' is to be used to remove or replace a bulb which dependsffrom a ceila ingi onthe'ulikegthei. cu -51am used, ithe cup beingiplaeediniengagement with the bulb and then by turning the handle 10, the'gears' f V '9 and llwill cause the shaft 7 to be turned so thatthe cup 13 will be rotated in one direction or the other, according to the direction of movement of the handle 10 andthus the bulb canbe screwed into-its socket or screwed outof the socket.

the horizontal cup 19:canbe,used,this cup being rotated through the gears 14, 16 and 17 standing on the floor cannot reach the same.

It is thought from the foregoing descrip- When the bulb ext-ends horizontally or at an angle and it is impossible to handle the same by the topcup,

tion that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combi- 5 nation and arrangement of the several parts,

provided that such changes fall within th scope of the appended claims. 7 I c. What I claim is i 1. A device of the class described comprish V i 10 ing an elongated supporting strip, upper and lower brackets connected therewith,"means whereby the lower bracket can be adjusted j r lengthwise on the supporting strip, a'sec-" tional shaft journaled in, the brackets with the upper end of'the shaft projecting beyond theupper end of the strip, means for detachably connecting the sections of the shaft together, a toothed wheelrotatably supported by the lower bracket, a pinion on the shaft engaging the toothed wh'eel,-a handle for turning thewheel, a chuckconnected: with the upper end ofthe shaft and avacuum cup carried by the chuck; I

- 2. A device of the class described comprising an elongated supportingstrip, upper and lower brackets connected therewith, means whereby the lower bracket can be adjusted lengthwise on the supporting strip, a sectional shaft journaled in the br'acketszwith 39 the upper end of the shaft projecting beyond the upper end ofthe strip, means for detachably connecting. the sections ofthe shaft together, a toothed wheel rotatably supported by the lower bracket, a pinion on the shaft engaging the toothed wheel, a handle for turning the wheel, a chuck connected with the upper endof the shaft,'a'.vacuu'm cup H carried by the chuck, a stub shaft journaled in the upper bracket and extendinghorizontally, a toothed wheel ournaled inthe upper bracket, pinions on the upper .end of. the shaft and on the stub shaft meshing withthe wheel of the upper bracket, a chuck ca'rried by thestub shaft and a vacuum'cup carried bysaidchuck. V 1 In testimony whereof I affix my signature.
