Claims: I claim:

1. A block laying level indicating device adapted for use with a building block of general rectangular configuration having a top and a bottom face, front and rear walls, and opposing end faces, said front and rear walls being connected by webs spaced from each other to provide a plurality of holes extending from the top through the bottom faces, said device comprising:

a planar base;

a plurality of support members on said planar base, said support members being adapted to bear against the top face of the block on which the device is mounted;

level detecting means on said planar base for visually indicating the complete horizontal level position of the block on which the device is mounted when the block is laid; and

a positioning member connected to the planar base and extending perpendicularly and downwardly therefrom, said positioning member having an inside face forming the 90.degree. angle between the planar base and the positioning member and an opposite outside face, said positioning member having a length and weight such that when the block is placed in a vertical position with one of the end faces directed upwardly and the device is placed on the block by inserting the positioning member into one of the block holes until the support members bear against the top of the block and the outside face of the positioning member bears upon the block web forming the hole, said planar base will be maintained in position with the support members engaging the top face of the block thus orienting the planar base in a vertical plane and the positioning member in a horizontal plane.

2. The invention as set forth in claim 1 and wherein the planar base is a rectangular plate having an inset wherein the positioning member is affixed to the plate.

3. The invention as set forth in claim 2 and wherein the plurality of support members comprise three screw members threadably carried in the plate for adjustably positioning the plate in a level manner prior to use in block levelling.

4. The invention as set forth in claim 1 and wherein the planar base is a triangular plate having an inset wherein the positioning member is affixed to the plate.

5. The invention as set forth in claim 4 and wherein the plurality of support members comprise a fixed support on each corner of the triangular base.

6. The invention as set forth in claim 4 and wherein the positioning member is hingedly carried in the inset of the triangular base and stop means are provided on the base to provide perpendicular orientation of the positioning member with respect to the base.

7. The invention as set forth in claim 1 and wherein the level detecting means comprises a "Bull's Eye" level device for complete level indication.
