,- and more particularlyfto't'ools that are employed by workers in the building trades.V

The primary object of this invention 1s to rprovide a hand tool that combines` sev-V eral tools in oneand furnishes a useful arti-.

plumbers, etc., with Ya consequent savingfofl time,. laborland expense. y y' To produce such a tool, a. combination oit Y an adjustable miter square, -aperpendicular' and-a horizontal level bubble, a'rule fand a sliding marker'. adjustable on a scale, effected. I f i. A .particular `advantage of this -comb1na- 'tion isithe eliminationlof several separate tools, which are commonly larger and :more cumbersome, thus -permittin g the `artisan to carry in his pocket'this` small hand tool which replacesv several others.

Some. of the numerous'uses tofwhich this tool may be applied are :to mark cutting lines on interior and exterior trim,baseboards, capping, casings, s1d1ng,corner boards. Aand all mill work; to get miterangle'for anyl cut.; to get plumb andbevel lines;` andto scale small dimensions@V y 1 A 'further advantage lies ment and construction of parts`wh1chfgproduce. a tool capable of smooth precisionin its adjustments, facility inits manipulation, and

one in which the appearance of sturdiness,

qualit-y and master workmanship are apparv- Y ent;

The foregoing constitutes a recitalosome of the advantages of my'inventionwhich is r more fully explainedy by reference to the drawings, in which:

way andguide'for block 20.

The frame memberl is recessed take thetixed plate-5 :which isheld yimmovable by screws 22 and 23 to said member l'. Y i

Said member 1 isslotted as at 25, which l slot is provided.with a peripherical shoulder 26. Through this slotextends a`screw'27 {ixyedly attached to said block 2()r A thumb nut- 28screws down Ionto a washer 29 .which washer rests upon the'aforementioned shoulder 26'. 'i

A small spacer block 30 is inserted between the plates 5 and 6 laround the screw 14. It i Vis not essential to the operation ofthe tool. i

The blades 3 and 4 lie between the plates y5 'i and 6 asbest shown in Figure 4, and are piv- 'im i' otally held to the sliding block 20rby pins 32 'and 33. Each -blade is also-furnished with a pin pwhich pins extend out oneach side and on one side engage the straight slots 36v cut in the stationary plate 5 while on the other side they engage curvedy slots 37 cut in plate 6. In Figure 6, plate 5 which in theassembly are 'counterl sunk and lit into holes39 and 40,

is held immovable by screws 22 and 23which is also provided with a slot 41, which slot coincides with slotwhen assembled, while the hole 42 accommodates the screw 14. The lower part is cut away as at 43 to lit over the bubble 12.

In Figure 7, pla-te 6 which is the movable plate is provided with an opening 45 which is designed to takefblock 20. The opening 45 is made sli htly longer than the block as shown at 46, 4gure 4, but is a sliding lit as to width. The upward and downward play is necessary to prevent a binding taking place whenl the blades are moved in or out, since the vertical movement of the plate 6 is dependent-upon the shape ofthe curved slot 37, and the travel ot the block dependent on the straight slot and movement oi' pin 35.

In actual practice the block 2O travels further than the plate 6. The slot 47 is provided to-clear the screw 14 as the plate movesdown# ward. The bottom part is shaped as at 48 to t over the bubble 12. d

In plates 1 vand 2 a correslionding opening 49`is furnished to make the bubble 12 visible from either side. y

Provided in one of the legs, or, it desirable,

i in each leg, is a plumb bubble 50 with an opening 51 and a second opening V52 provided at a right angle to eachother to allow the bubble to be seen from either side of the leg or from the edge of the tool.

, used by the thumb to push it along. also with flat runners 57 and `58 which `travel the slots 7. y

A portion of the metal iscut away as at 60 and 61 to lighten the tool for carrying purd poses.

i curvilinear movement. By

The movement which takes place when the blades are changed from one angle to an other is made up ol three components: a. horizontal movement,.avertical movement, and a the above combination a result is obtained that produces a 3 and 4.

rotating movement with neither a pivot nor a fixed point as a center. i

`As plate 6 is forced into the `tool the pins 35 which engage both slots 36 and 37 move outward along slot 36, due to the pressure exerted by slot 37 in its downward move# ment. But said pins are iixed to the blades Therefore the blades move outwardly, but since the blades are rotatably pivoted to the block 20 it follows that the block 20 moves downwardly, thus rotating the arms 3 and 4 on the pins'as' the pins 35 continue to move back in the slots 36. The movement is completed, as shown in Figure 5, when the pins 35have run into the ends of `slots 37 which brings the arms `3 and 4 into a horizontal position.

At any ment may e stopped and the-thumb nut 28, which, before commencin the movement, had been loosened, may be tightened, thus settino the armsifixedly in any angle desired.

When; the blades 3 and 4 are sheathed in the slots 7, the tool ypresents `a smooth surtace, which makes it difficult to get `atthe blades to start them outward. To overcome this a point 65 is provided on the movable plate 6. This extends at'all times out of the slotat the top of the tool. 'By placing the point on Vany suiiiciently hard surface the Aplate G is pushed .inward andthe blades come out, providing a simple eilicient means of op eration. i

The foregoing description and drawingsshow only one embodiment of my idea and since it is possible to refine and improve it without departing from the scope of the drawings, specifications or appended claim, I reserve this right of modification; I claim i In a combination tool, a frame, a member having slots therein and being fixedly secured to said frame, an adjustable member slidable in said frame andhaving a slideway formed int in this operation the moves' therein, a block disposed in said slidewav, Y

adjustable blades `having their ends pivoted on said block`r said adjustable member having arcuate slots formed therein, and pins secured to said blades Iand extendinginto said slots in both the fixedly secured and the adjustable members-` EDGAR G. MORIN, Jn.
