BRICK.

SPECIFICATION forming part of Letters Patent No. 295,692, dated March 25, 1884:.

Application filed January 7,1884. (No model.)

To all whom it may concern;-

chusetts, have invented an Improvement in- Bricks, of which the following description, in connection with the accompanying drawings, is a Specification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel form of brick, by which a wall may be made stronger and better than when ordinary bricks are used.

My invention consists in abrick having rabbets and projections, as Will be hereinafter described and claimed.

Figure l represents in perspective part of a Wall composed of bricks embodying my invention. Fig. 2 represents a corner brick removed 5 Fig. 3, a cross-section`oil Fig. 2; Fig. 4, acorner brick; Fig. 5, a cross-section thereof', and Fig. 6 represents a brick for the main body of the Wall.

The brick A,to be built into a Wall, as shown in Fig. l, at the left of the corner, viewing the said figure from the position of' the arrow2, is provided at its Linder side, at its longer edge, with a projection, a, and at its end With`aprojection, c, While at its upper side, along its longer edge, the said brick has arabbet, c3. and along its end a rabbet,

enter into the rightliand portion of the Wall and extend'back from the corner, differs from `brick A, in that the projection b, along the longer edge of the brick,is at the side opposite The brick B, to

that occupied by the projection a of brick A, the latter brick being termed a left-hand brick, while brick B is termed a right-hand7 brick. For walls one or more bricks removed from the corner the end projectioinc, and end rabbet, @will be omitted, leaving the brick as shown in Fig. 6. The `projections a a2, 85o., are sufficiently thinner than the Width of the rabbets c3 a* to enable the rabbet tg holdan amount of mortar sufficient to permit each brick to be properly set level and plumb, and to hold it. But very littlemortar is used between the plainV parts of the bottom and top of each brick.

A wall built from brickssliaped as described will be very strong, may be rapidlylaid, and With the minimum amount of mortar.

As an improved article of manufacture, a brick having projections at its under side along its longitudinal edge and across one end, and having rabbets at its upperside alongone1ongitudinal edge and across one end,substantially as shown and described,whereby a strong and neat-appearing corner may be formed, substantially as set forth.-

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. 1
