PATENT OFFICE.

S'l. JOSEIII, MICHIGAN.

DESIGN FOR A BUILDING-BLOCK.

To all whom it may concern:

Be it known that l, EUGENE ll. l,E\v1s,a citizen of tle l'nited States, and a resident of St. Joseph, in the county of lcrrien and State of Michigan, have invented a certain new and original Design for Building-Blocks, of which the following is a specification, rei'- erencc being had to the accompanying drawings, forming a part hereof.

The leading feature of my design consists of a rectangular margin or border extending continuously around one face of the oblong block or brick, alternate elevations and depressions within said margin or border, with certain of the elevations or raised portions contiguous to the margin or border, and a groove in said raised portions contiguous to the margin or border and parallel with the same.

In the drawings, Figure I is an elevation of a rectangular building-block showing my design. Figli is a longitudinal sectional view through the block on the line ir .n of Fig. I. FigIII isatransvcrse sectional view through the block on the line y y of Fig. l.

A is the rectangular margin or border which extends continuously around the sides and ends of the front oblong face a of the lmilding block or brick. Within this margin or border are irregular-l)v placed the sunken portions, depressions, or cavities Il l5', which are separated by the raised portions C C C, which lie in a plane [lush with the margin or border, or substantially so. 'lhe series ot' elevations C extend inline along the middle of the building-block, while the elevations are at opposite sides ot' said middle series, and they lie contiguous to the side edges of the block. The depressions or cavities are irregularly and arbitrarily placed, and the sides h b of each depression or cavity lie at an angle to eachother and converge to the bottom Ii' of such depression. Some of the depressions, as l, are completelyisolated from the adjacent cavities, while others of the depressions, as l', are connected to one or more cavities by shallow grooves I), which extend through the tace or t'aees of the elevations or raised portions. In the raised portions contiguous to the margin or border A,I provide the groove E, which extends parallel with the border; but as the raised portions within the border are interseeted and divided hy the depressions or cavities this groove does not extend continuously around the block and its marginal border, but is only used at certain irregular intervals where the raised portions are contiguous to the marginal border. The irregular cavities or depressions alternating with the raised portions within the border presents to the eye the combined effect of a smooth marginal borderand elevations on the plane ot' or Hush with said border, and which are divided or interseeted by the irregular cavities or depressions placed arbitrarily in the face of the block, all being within and inelosed by the margin or border.

lIavingthus described my invention, what I claim is- The design for a building block herein shown and described, the same comprising the raised marginal border, the irregular cavities or depressions within said bordel', and the raised portions alternating with said cavities and lying flush with the raised border, as sot forth.

In testimonyY whereof l allinY mysignature in presence oi' two witnesses.
