GEORGE E. LEGENDRE, or :BRIDsnr-'01mg coNNEcmicUn;

To all whom Vit may camerati 'I Befit known thatI, GEORGE E. LEGENDRE, t a subject ofthe King of Great Britain 're-I sidingl at Bridgeport, county of'Fairneld, :A State of Connecticut, have invented yan c Improvement'in Extracting-Tools, of which:

theffollowing is a specification. ,n

This invention relates'to extracting tools of the type adapted to withdraw fcotter pins,

nails, spikes, or thelikefrm their holding..

means, and the'object of the; invention is to provide a tool of this character which 1s extremely simple in structure, durable andv etlicient in use, and cheap to manufacture.Y

VVith'the above and other objects in view, the invention comprises the construction, arrangement and combination of parts as now to be fully described and hereinafter specili- 1 cally claimed. y

lIn the accompanying drawing forming a F lgure 1 1s aperspectlve viewof the device'` of the'invention, `showing the manner in which my improved extracting tool is put to use; andY I Fig. 2 1sa fragmentary, perspective view of a modified form of the invention. p

c 10 denotes a ratchet bar and 11 denotes Y teeth thereon. The ratchet barV is removably and slidablyV carried vby a guidel block 12 having ears 13 to which gripping levers 14 are pivoted as indicated at V15. Pivotally socketed in the Ygripping levers, as indicated at416, are links 17 the opposite' ends of which are pivoted to ears .18 on a slide block 19 arranged on the ratchet bar as shown.

' Spaced apart lugs 20 on Vthe slide iblock V V .v of the pawl and resting Yagainst'the slide -block' servesto normally -hold thezpawl in engagement with the teeth, as will bereadily understood. YYAs shown inFig. 1, Vthe lower pivotally carry'a pawl 21 which is adapted to engage the teeth onV the ratchet'bar, as

disclosed in'Fig. 1. A pin' 22 vpassing Vthrough lugs20 and the pawl is the means shown for supportingthe pawl. It willcbe apparent that the'pawl maybe pivoted to the slide blockvinany ordinary manner. A flat spring 23V attached to the lower portion endjof the ratchet bar is provided with a shank 24 having a hookV 25 adapted to engage `a cotter pin or the like. As shown in Fig. 2, the lower endV of the ratchet. bar carc ries a fixed jawY 26 `and a pivoted jaw 27 In Fig. 1 the manner of using the imlevers. f Y. Having thus described my invention, IV

that the ratchetbarwill be` causedvto-slide upwardly through the guide block and the,V f

lower edge is about in line with thel upper portions of thejaws. VWhennow thefgrip-V vping levers are forced toward each other ,l and the ratchet 'bar is thus caused to slide upwardlyin the guide block, the jaws Wm Y pass into the,V lower portionfof the guide block and thus'be heldinrgripping position on 'they nail,, spike or the; like,-"being It will be evident that inf'this i y form of the invention, as wellas intheform v disclosed in Fig. 1", Athe guide block must be supported in fixed relation with respectto pulled the nail or spike to be pulled before the gripf f I ping levers are operated.

The ratchet bar may bemadeanyl desired i length. Y Consequently,- the Ysupporting means of the invention disclosed in Fig. V1, maybe locatedA at any reasonable distance `from the cotter `pin,jor .the` like, to be withdrawn. f

Likewise, the gripping levers may be made 90# for the guide block, in the case of the form, f i
