w I a wwwboz Mill/aw fi an/mv' toward the center of said piece, whereas when the square is arranged so that the rollers 11 will engage the periphery of the piece as shown in the drawings, this manner of adjusting the slotted blade could not be attained, owing to the point or apex contacting with the periphery of the piece. In using the ends of said flanges in this manner, the square may be arranged so that the slotted blade may be adjusted to find one radius, after which the square may be arranged in another position and the slotted blade adjusted, to find another radius at right angles to the first radius and intersecting the same, thereby ascertaining the center of the circular piece. In adjusting the slotted blade the slide 22 of the square is adjusted so that the mark on said slide will cooperate with anyone of the graduations at the edge of the slot in said blade. Upon the faces of the arms opposite the faces to which the flanges are attached, are provided lugs 8 on which rollers 11 are j ournaled. These rollers are also designed to engage the periphery of a circular or polygonal shaped piece, as shown in the drawings. lVhere the two arms form a junction, as indicated at12, a pair of apertures 13 and 14 is formed. Referring to the drawings it will be seen that a slotted blade 15 isprovided having an extension leg 16. This extensionleg is offset from one face of the blade 15 as shown, while the lower end of the blade terminates in a V-shaped portion 17, the apex of which alines with one edge 18, of the extension leg 16, so that when the leg is utilized'in finding the center of a circular piece, the apex 19 of said V-shaped portion 17 will engage the periphery of the circular piece, at the same time the rollers 11 engage the periphery. The two arms of the square are provided for the purpose of supporting said rollers 11, so that the rollers will engage the periphery of a circular or otherwise shaped piece so that when the apex 19 engages the periphery of the piece, the tool is well balanced with reference to the piece, so that the leg 16 of the slotted blade will always extend radially to the piece. This same result is attained when the ends of said flanges 6 engage the periphery of the piece. But in the case when the ends of the flanges engage the piece, the apex 19 is not utilized. When either the rollers 11 orthe ends of said flanges engage the edge of a straight piece as shown in Fig. 6, then-the tool may be used as a gage, the scoring or scratching tool 30 upon the leg16 is used to score a line, indicating where the piece should be cut. By permitting one of the rollers 11 of the square and the apex 19 to engage the edge of a straight piece as shown in Fig. 5, andv by adjustingthe slotted blade in various positions, different lines may be scored by a pencil sliding against one of the arms of the square, so as to indicate various miters, asvshown in Fig. 5. By disposing the extension leg 16 in this manner and scoring a line and rearranging the device but in a similar way using another radius, and scoring a second line intersecting the first one, the center of the circular piece may be located. As before stated, in using the instrument in this way the apex 19 and the rollers 11 should always engage the periphery of the piece.
The elongated slot 20 of the blade 15 has its longitudinal edges beveled, as shown in the transverse sectional view, as at 21, and an elongated slide correspondingly shaped in cross section and designated by the numeral 22 fits the slot, from the opposite side of the blade upon which the square is arranged. This slide 22 is provided with a pair of lugs 23 and 24, the lug 24 being threaded. These lugs pass through the apertures 13 and 14, that is, the threaded lug 24 passes through the aperture 14 while the lug 23 passes through the aperture 13, there being a thumb nut 23 upon the threaded lug 24 engaging the square at the junction of the arms thereof, to hold the square in position. By this construction the square may be adjusted to any position relative to the apex of the blade 15, or adjacent one end or the other of the elongated slot. The blade 15 is provided with a.hollow handle 25 having a threaded closure 26, for the reception of the slide 27. The slide 27 is provided with an opening 28 to receive the extension leg, there being a thumb screw 29 for holding the slide 27 in adjusted position. This slide 27' has a scratching or scoring tool 30 extending transversely thereof, being held in adjusted positions by means of a thumb screw 81. By placing the slide 27 upon the extension leg, and adjusting the same in'the desired position, the instrument may be used as a carpenters or other mechanics gage tool, as illustrated in one or two of the figures. 4V hen the slide 27 is not employed, the same may be placed in the hollow handle.
The slide 22 is provided with a mark 22 scored thereon transversely, which mark is designed to cooperate with the graduations 22 on one side of the slotted blade 15. This slide is set so that the mark 22 will register with one or another of the graduations 22", so that the square may be set in the proper position in order that the rollers 11 may assume positions relative to the apex 19, in
order that miters of different angles may be scored on a straight strip as shown in Fig. 5. In other words, if the mark 22 is set opposite the graduations 4, a miter of one angle may be scored on the strip, and if the mark is set opposite the graduations 6, or opposite the graduations 8, a miter of another angle may be scored, as shown in Fig. 5. In scoring these miters the apex 19 and one of the rollers 11 engages one edge of the strip, one arm extending angularly across the strip, after which the miter is scored or marked.
It is deemed unnecessary to further describe the various uses of the instrument or tool, owing to the well defined illustration of the accompanying drawings.
