UNITED STATES PATENT OFFICE.

FRANK W. BUTTEEW'ORTH, OF DANVILLE, ILLINOIS, ASSIGNOR T0 WESTERN BRICK COMPANY, OF DANVILLE, ILLINOIS, A CORPORATION OF ILLINOIS.

SANDED TEXTURE BRICK.

Application filed January 9, 1922. Serial No. 527,813.

To all whom it may COILC'QWt.

Be it known that I, FRANK WV. BUTTER- WORTH, a citizen of the United States, residing at Danville, in the county of Vermilion and State of Illinois, have invented certain new and useful Improvements in Sanded Texture Brick, of which the following is a specification.

This invention relates to a new and improved texture brick and more particularly to a brick of this character, the surface of which carries a film of sand.

It has been the practice in the manufacture of common brick to'place sand upon the faces of the brick. This sand serves to prevent the faces of juxtaposed bricks from adhering to each other when the brick are burned in the kiln. The brick are placed in the kiln. on edge, that is, with the beds of the brick extending vertically. This method of placing the brick greatly facilitates the burning since it provides an increased number of vertically extending passages in the piled brick in thekilns.

A number of varieties of what are called texture brick have heretofore been manufactured, these brick having the surfaces of the faces and heads of the brick deformed in various manners. This deformation obviates any high lights on the surface and is, therefore, considered desirable for face brick, it has generally been considered impractical to sand the faces of such brick in view of the surface deformation and the brick have consequently been of necessity placed flat or lying upon their beds when stacked in the kiln for burning. This has resulted in considerable loss in efficiency in burning as has been stated.

In my prior Patent. No. 1,353,515, granted September 21, 1920, I have disclosed a texture brick having its surface provided with closely spaced indentations which serve to break up the surface and form a texture brick. The brick described in this prior patent does not have its faces sanded and is, therefore, burnt while placed flat in the kiln.

According to the present invention, the brick has a film of sand applied to one face and to both heads of the brick. After the film of sand has been applied, these surfaces of the brick are worked to form a series of closely spaced, relatively small indentations. The working is such that the brick surface between the indentations is not touched or disturbed by the workingelements and the film of sand remains adhering thereto. That portion of the film of sand which Was upon the indented portion of the surface is thrust. downwardly into. the

material of the brick, being forced into the surface of the indentations. The briclris then burned by being placed on edge or resting upon one of its faces. Due to the fact that the roughening consistsin indenting or depressing portions of the surface, the entire contacting portions of the adjacent bricks are plane and are covered with the film of sand which prevents them from: ad hering during the burning. A suitable form of machine for providing these indentations upon the brick surface is shown in my prior Patent, No. 1,191,925, granted July 18, 1916, although obviously the surface may be indented by any suitable machine which does not disturb the surface between the indentations. A

I have illustrated a preferred embodiment of my improved brick in the accom panying drawing, the single figure of which tions 8. The indentations shown are such as would be formed by my machine disclosed in my prior patent above referred to. They comprise a closely spaced series of short and narrow indentations disposed in substantially parallel lines. The surface of the brick between the indentations is not disturbed in the process and as indicated in the drawing, this surface has adhering thereto a thin film of sand. The sand which was located upon the portions of the brick which have been indented has been thrust into the indentations and into the material of the brick.

It is to be understood that the sand upon the plane portion of the brick is not worked, pressed or in any way forced into the surface but is simply applied to the moist surface of the brick making material in such manner as to lightly adhere thereto.

My improved brick is capable of being placed on edge in the kiln for burning which permits burning of the highest efliciency. It provides moreover a texture brick in which the adhering film of sand aids in breaking down or preventing any high lights from appearing upon the unindented surface of the brick. The brick thus gives a highly pleasing effect when used in construction.

A brick formed with the particular shape of indentation shown is disclosed by way of example only and it is my intention to cover all modifications coming within the spirit and scope of the appended claims.

I I claim:

1. A brick or the like having'a substantially plane surface, said surface being broken by a series of spaced deformations, and'a film of sand upon the undeformed surface of the brick.

2. A brick or the like having a substantially plane surface, said surface being broken bya series of spaced deformations, and a film of sand lightly adhering to the undeformed surface of the brick.

. 3. A brick or the like having a substantially plane surface, said surface being broken by a series of spaced deformations, particles of sand worked into the deformed portions, and a film of sand lightly adhering to the undeformed surface of the brick.

.4. A brick or the like having its surface provided with a series of relatively small indentations, and a film of sand upon the remainder of the surface of the brick.

5. A brick or the like having its surface provided with a series of closely spaced, relatively small indentations and a film of sand lightly adhering to the remainder of the surface of the brick.

6. A brick or the like having is surface provided with a series of closely spaced, relatively small indentations, particles of sand pressed into the brick in said indentations, and a film of sand lightly adhering to the remainder of the surface of the brick.

7. A burnt brick formed of clay or the like having a substantially plane surface, said surface being broken by a series of spaced deformations, and a film of sand upon the undeformed surface of the brick.

8. A burnt brick formed of clay or the like having a substantially plane surface, said surface being broken by a series of spaced deformations, and a film of sand lightly adhering to the undeformed surface of the brick.

9. A burnt brick formed of clay or the like having its surface provided with a series of relatively small indentations, and a film of sand upon the remainder of the surface of the brick.

10. A burnt brick formed of clay or the like having its surface provided with a series of closely spaced, relatively small indentations and a film of sand lightly adhering to the remainder of the surface of the brick.

Signed at Danville, Illinois, this 4th day of January, 1922.
