improvement consists in 'aigiplying to a levelb'ody; such as one o fthis'type,the

pointed holding means preferably constructed as follows. At two or more points longitudinally of the levelbodygthe" latter is provided with transverse'threaded bores therein. screwing into thesebores is an externally and internally threaded "sleeve 6 having one end open and providedwith an ann iilar flange 7,* and having its other end provided With a similarflangefandvvith tern'ally and internally threaded sleeve an aperture therethroug'h. This is preferably accomplished by utilizing a short exjsection fiflhaVing an annular. end flange 9.

The external *diametenof the section 8 is equal substantially to the "internal diameter -of theniainsleeve body 6; Themain' body 01"? the sleeve member is screwed through the level bore first, 5 and the sleeve section 8 is then screwed intothe open end ofthe sleeve Girointhe oppOS'ite-sideof the body, 1?

this being-theeasiest method of assembling. Subsequent to this,-these tWQ' parts maybe rigidly interconnected against movement in any suitable 'Inanner, so that thereafter they may; not beseparated. tice tli'e eonstruetion shown in the drawings interlock betvreen the main body 6 and the shortseotion 8' of the sleeve structure in'ay body after once having been attached." I

In ordinary pracmay' be enigloyed inasmuch as-the thread I be made stifliciently firth to prevent relative movementthereafter." It will be evident that the flang'es 7 and 9 will prevent the sleeve from being removed from thefle'vel Fronitlie flange end 7 of the sleeve body,-*

a pointed pin 10, is'fscrewed" into and through the threaded interior bore of the sleeye secti'on 8 u'ntil'thepointed end Of thejii-irprojects beyondthe face of theflangedend driver slot therein so that a screw driver 9 of said sleeve section'. The rear-endofi this pinjis provided with ahead 11 limitmay have its end inserted through the open flanged end 7 of the sleeve structure to engage With the slot inthehead of this pin; and i to either retract the pointed end of the p'in lvvh olly within the sleeve structure or.

project the same therefrom as may be de sired.

.'.;Z[The. overall length of the sleeve member in'clding the flanged ends 79' and projected pin 10, is preferably less than 'the greatestbverall thickness of the-levelbody,

so that when the rear end of thesleeve inem ber is screwed up,"the said sleeve may 'be positionedto have its flanges 79 wlthin the plane of the extreme outer faces of the level' body and, therefore, in a' position where" they will not interfere witlrtlie ordinary handlingv of the tool. .The sleeve is also, preferably,- of such'length' that, when itis; screwed up to bring theiouter end 7 against the adjacent face of the level body,

the inner end 9 will be positioned approximately inthe planeof the opposite inner face of the level body; With the holding :pin 10 projected from this. outer face 9, it will be evident that in this position of the level body, the pins may be'forced. into the -,w0o d,.; for instance, against which the level ,the level body, that it may be positioned body rests, and will enable the workman to '.hold the adjusted level with one hand while .Withthe other he scribes or otherwisemarks .the desired line UpOILtlle wood. It will also be evident that when the level is not being used for such work, the points of the pin .10 may be Withdrawn Within the sleeve member by inserting the end of a screw driver through the open end 7 of. the sleeve ;and screwing the pinlO inside of the opposite end-of said sleeve. Furthermore, inas- Tmuchas the parts of a sleeve body are 'fixed against relative .movement under ordinary circumstances, the pin-carrying sleeve membercan'not be lost from the levelbgodyr Furthermore, the sleeve member is of such length relative to the overall thickness of relative thereto soias not to interfere with v ordinary work when the holding device is {not needed. I have herein. described and shown a specific embodiment of my invention, butwit will be evident that the inven- ,tion is ,susceptible of modification both in structure and in therelative arrangement of parts within the spirit of the invention and the-scope of. the, appended claims.

. \What I claim, therefore, and desire-to I I .sec'ure }by Letters Patent is:
