The caliper 23 further as shown in FIGURE 4. f

` There is further provided a movable or adjustable arm which is indicated generally bythe numeral 35, FIGURE 3, The iirst portion 25 of the body membe'r`21 is provided with an elongated slot 33 which terminates in an enlarged circular section or opening 34, FIGURE 4. The

arm has calibrations or scale markings 36 thereon, and

the arm 315 includes spaced parallel longitudinal side edges f 37 and 38 as well as a flat end portion 39' and a tapered or beveled end portion 40. Y

`As shown .1in FIGURE 3for example `the arm 35 is provided with a longitudinally extending slot tI-shaped to include a` rst section 42 and a second-section 43,` the second section 43 being of greater size than the lirst section 42. f p

The `numeral 44 indicates a'bolt which is provided with an enlarged head 45, and the head 45 includes Vspaced apart arcuate or curved edges `47 andthe head also includes spaced parallel ilat surfaces 48. The securing element `44 includes a threaded shank 46 such as Vadapted to project through the slots such as the slots.l 41 and 33, and a fastener or knurled nut "49 is arranged in threaded engagement with the threaded portion tof the shank 46, FIGUREJZ. j t t As shown in FIGURE 4 for example, there is provided a plurality of radially disposed lines or scale markings 5,0

vwhich permit the.v tool of the present inventionto be used for measuring or marking at diiierent angles.

From the foregoing, it is apparent that there has been provided a4 toolwhich is in the. nature of a combinationv Y bevel square, and in vuse the parts-may beV arrangedas shown in FIGURE 1 for example so that the arm 35 has its longitudinal axis arranged at right angles' to the longitudinal axis of the -body member 21 whereby right side edges and the body Ymember 21 is provided on one side thereof with a rectangular recess which is indicated generally by the numeral 22,'ther`e being spaced parallel.v flanges or ribs 23 on opposite sidesof the recess 22; The

numeral 24 indicates transversely disposed shoulders on the ends o f the ribs 23.` The `ribs 23v extend from one end of the body member 21 and terminate along a line transversely of thebody member 21 at a point -sbstanf provided on thebo'dy membera second portion 26 on the opposite side ofthe shoulders `24.` As shown in FIG- URE 5 for example the second portion 26 is of greater angles, 'or the `Vlike "canbe readily;` measured or marked o, The arm 35 is provided with the calibrations or scale markings asindicated bythe numeral 36 so that accurate I measurements Acan be made, and withthe parts arranged asshown in FIGURE 1, the edgev38, abuts the shoulders y Y n 24 so that for example a 290. angle will be provided between the edges 3'7 or 38 and the Vside edges ofthe b ody member 2li.V The `nut 49 is adapted to be tightened on the securing element 44 sofas to maintainv theparts imf mobile in their adjusted position. It is to be noted that as shown in FIGURE '2 for example, the head 45 of the securing element 44 fits Vsnugly in `the slot. 41so that yasl shown in'FIGURE 2 for examplethe tool 20 has oneside thereof which is at whereby the tool canrbe laid down on a Work piece or other iiatsurface without having any' projections interferingy therewith. `That is, as shown in FIGUREMZ the vright side of the tool provides a generally` .flat surface which is adapted to'be laid down on a work` Thus, the thickness of the portion 26 is equal to thecombined thicknesses of the portion` `25andthearrn35. l

When the arm 35 is to be adjusted, lthe nut 49tis loosened, and after the arm 35'has beenrnoved to its t sheet or other area.

desired position, the nut 49 is tightened in order to maintain thearm immobile in` its adjusted position. The head`i415 of the Vbolt 44 includes'pthe dat opposed side the body member 21.

surfaces 48 which snugly engage the section 43 of the slot 41, and the slots terminate in enlarged circular portions which can receive thev arcuate surfaces 47 of the head 45 when desired. The caliper 28 has its blade or shank 29 slidably mounted in the groove 27 so that for example a workman such as 'a work piece 32 can be measured by arranging the work-piece or article 32 between the portion 30 of the caliper and adjacent end of The scale markings 3.1 on the blade 29 provide a means for accurately measuring the diameter such as the diameter of the article or member 32. The groove 27 Ihas a dove tail shape as for example as shown in FIGURE 9 and the blade 29 has a corresponding cross-sectional configuration so tha-t the blade 29 is free to slide in the groove 27, but nevertheless the blade will not accidentally fall out of the groove.

As previously stated the arm 35 can be arranged so that its edge 38 vabuts the shoulders 24 as shown in FIGURE 1 in order 'to permit the tool to be used for measuring or marking right angles. Or, las shown in FIGURE 8, the arm 35 can be arranged in a different position so that an edge such as the edge 3S will coact with a radial line 50 in order to permit measurement or marking of different tangles. Or, `as shown in FIG- URE 12 the beveled edge 40 of the arm 35 can abut a shoulder 24 to provide measuring or marking a. 45 angle as indicated by the numeral 51.

The parts can be made of any suitable material land in different shapes or sizes.

The provision of the slots 33 and 41 through which extends the shank 45 of the bolt 44 provides a means whereby the arm 35 can be adjusted `or moved to different positions on the body member 21 as desired. Thus, the tool or instrument of the present invention can be used as fa square, or else it can be used as a protractor, as tor example due to the provision of the radially disposed lines `5(lwhich are printed or otherwise arranged on the body member. rThe caliper 28 has measurement markings 31 thereon. The handle or body member 21 is provided with the space or recess l22 for the arm to lie in when closed.

Thus, it will be seen that there has been provided a combination bevel square which will replace the -necessity of having three separate tools such as three separate wood working tools. When the arm 35 is pressed firmly against the shoulders 24 of the body member 21, and the nut and bolt tightened, the arm 35 will be at right angles to the body member 21. With the `arm 35 moved so that the beveled end 40 rests against a shoulder 24, as for example as shown in FIGURE l2, then the arm 35 and the body member 21 coact to form a 45 tangle as vfor example as indicated by the numeral 51. The angles 50 marked on the body member help to position the erm 35 in the proper location, as for example for specific tangles or for determining an unknown angle.

An important feature of the present invention is the ability of the tool to lie flat on a board or paper when making layout drawings, or drawing any angle which cannot be done with standard beveled squares or combination squares. In addition the tool will fold small enough to be carried in the pocket by loosening the nut bolt and folding the arm over the body member. The tool can be made of wood, plastic, metal or the like.

The arm 3:5 is adapted to lie between the ridges or ribs 23 when the tool is folded so as to provide a compact folded unit. The shoulders 24 iare `at the edges or ends of the ridges or ribs 23. The space 22 is for receiving the par-t Aof the arm 35 adjacent thereto when the device is in the folded position, `and the remaining portion of the arm 35 extends parallel to the body member 21.

Minor changes in shape, size and rearrangement of the details coming within the field of invention claimed, may be resorted to in actual practice if desired.

What is claimed is:

A bevel square comprising an elongated body member having on one face thereof a rib extending along each of the side edges of said body member from one end of said body member to a point substantially midlength of said body member, the inner ends of said ribs constituting shoulders disposed along la lline which is transverse of said body member, the portion of said body member remote from said ribs having an elongated longitudinally arranged slot, an elongated arm having a longitudinally extending closed slot, said arm being disposed in tace to face relation with respect to said body member portion, a bolt extending through and slidable along said body member portion slot and said arm slot adjustably connecting said arm to said body member, one end of said arm being beveled at an angle of forty-tive degrees with respect to the longitudinal axis of said arm, said arm having a side edge abuttingly engageable with said shoulders to define with said body member a ninety degree angle and when positioned with the beveled end abuttingly engaging said shoulders defining with said body member a forty-five degree angle, said arm being movable to a position between said ribs when in a none use condition.
