One of theimporta-nt objects of the present invention `is to` provide a compound tool,

which includes a l'square, rule,l plumb and,v

A further object'isvtoprovide a-combina' tion tool that-is compact, the p arts being so arranged'as to Lpermit any oneof the aforementioned instruments to be used whenever desired. f

A further object is to provide a combina-' tion tool which includes a means for securing the swinging arm in a folded-position within` In the accompanying drawings, forming a part of this application and in which likev numerals designate like parts throughout the several views: y

V,posite'side facesfof the stocks are cut out along their longitudinaledgesto receive the metallic strips 2,`any appropriatesecuring means being driven through thcsesti-ips'into the stockfl'as shownv atB, and-'will befobserved that'the outer" faceslof thesestrips lie flush with the lrespective-"side faces ofthe wooden stock 1 Certain of thesemetallic strips provide a means wherebyfthe tool may" "be used as arule, andto this endv graduations are arranged on the outer face ofsuch'strips as'indicated at 4, in Figure-1.

Metallic wear plates 5 andl 6 are secured on the y'ends ofthe stock 1 and'one sideedge of the jwearlplate 6 is formedwith .the graduations'7, as also clearly shown `in Figure l.

:i 'Thetopof this .woodenstock- 1 is- Jformed i with the longitudinally extending recess or i A cavity 8,l at onefend thereoifand thelupper edge ofthewear plate 6 is orinedwitha slot 9 thatfcoinmunicates with theoi'lterend lof the recess SLT-The inner end of thisr'ecessyS- is bevelledl'as'l indicated at 10, land'furthermore .Y a notch 11 is arranged atthe top vof the bevelled end 10 in which a nailorithe like may be inserted for swinging the arm 12 upwardly. Y vThis .arm has lits outer end disposed within athe slot 9 formedzin the plate 6 andthe pivotal connection for the outer end of this armzcomprisesfa screw 18' 'thatisithreaded infatranso verse-opening provided therefor in one side of the -plate v6, t-herouter` end otthe YopeningV notapioj ect beyond the tace of theplate 6. A reduced unthreaded pin14 is formed on the inner` endv of fthe screw; and this pin extends .throughanfopening' provided ltherefor inthe outer end of the arm 12and'is` disposed with- The upper edge of the outer end portion of the arm is cut away to form a shoulder16 that engages with the upper face of the plate l6 when the arm 12 is swung upwardly to a Vertical position so that furtherv swinging movement of said ar1n'12'w1ll be' prevented.

The arm is provided with the graduations 17- on either or both sides thereof, whereby the same may be used also as a rule, and when Figui-e3, said' arm will cdoperate -w-iththe the arin Visdisposcd in the position shown in' stop to provide a square. c Y

The inner end of the vertically swinging arin 1 2 is notched as illustrated at 1.8, to

facilitate gripping the same, and for the pur# pose of holding the swinging-arm nra folded,

The stock 1 isformed in its ycentral portion with theithrough slot 21, in which-is arranged. a spirit level 22, as shown very clearly in :Fig-A ures 1 and 3 of the drawings.- Furthermore, v

the stock 1 has arranged inward-ly of its'ends the plunib beads 23, and the lower' edge of the vertically swinging arm 12 AVis cut out, Aas at '24, so as not-to 1interferewvith'the adjacent plumb head'23 and'to ypermit the upper edge,V i

of the arm 12 toflie Hush with the upper face of the stockl, when said arm is in a folded position and disposed in the recess 8.
