It is aimed to provide a novel block which may ' wardly extendinglugs 23 and inwardly extending grooves 24 are provided on the block H) at the surfaces H to slidably and ad-justably receive be usedin connection with work for laying out . points different angles to each other, particu ‘such lugs. larly 90°, and drilling them without removing ' It will be noted that a hole 25 is provided longi tudinally of .the block parallel to the bases and that it intersects the vertical center line between the work from the V block. In addition, it is aimed to provide such a block in which the work may be clamped and the cen the surfaces l2 and I3. - The blocks may be used ter line ascertained relatively to one base of the 10 in pairs or in any desired number in which event rods may be engaged with the holes 25 thereof ' block, and the block turned usually 90° onto an other base while maintaining said center line.v ‘Drilling may'be effected when the block is sup to line up the different blocks. ported on each base. The more speci?c objects and advantages will points at 90°. with‘ respect to each other and drilling vthe same without removing the work from the block. The accomplish this end, the center line of the work is ascertained by sup porting the'block while the work is clamped become apparent from a consideration of the de scription following taken in connection with ac companying drawing illustrating an operative embodiment. In said drawing—- , - It will be realized that the construction of th block is such that it can be used for laying out 20 thereto, on either of the bases l3 or 14-, and then turning the block onto another of such bases. The center line will be maintained and also will be 90° from the ?rst. The drilling is on; accomplished in the same way. In order to drill Figure 2 is a vertical longitudinal section taken ' 25 on a 45° angle rather than a 90° angle, the block on the line -2—2 of Figure 1 and is supported on its base M. Figure 3 is a plan view of the ‘block. Referring speci?cally to the drawing wherein The extent of the surfaces or bases l3, trans versely of the block should be approximately at like reference characters designate like or simi least one-third longer than the corresponding lar parts, the block is disclosed at l0, being gen erally of V shape and made of any desired ma 30 dimensions of the surfaces l2 so that the center of gravitywill not throw‘ the block off ofeither terial, usually metal or a plastic. Said block [0 has a V groove at H which is de?ned by walls base I3. For this reason, also, the correspond or surfaces l2 at 90° to each other and of the same ing surfaces that is 13-13, l2—l2 and I'l--l'l extent transversely of the block.
