FRANK W. WOOD, OF INDIANAPOLIS, INDIANA, ASSIGNOR TO THE DANVILLE BRICK COMPANY, OF DANVILLE, ILLINOIS, A CORPORATION OF ILLINOIS.
PAVING-BRICK AND METHOD OF MAKING THE SAME.
Application filed. December 29, 1914.
T 0 all whom it may concern.-
Be it known that I, FRANK W. WVooD, a citizen of the United States, residing at Indianapolis, Marion county, and. State of Indiana, have invented and discovered certain new and useful Improvements in Pavin g-Brick and Methods of Making the Same, of which the following is a specification.
In the manufacture of paving brick it is customary to form said brick with buttons or projections on one side adapted to space the courses of said brick uniform distances apart, forming uniform recesses or spaces between them to receive the cement, or other binding material.
These buttons have heretofore been formed by using a die with a depression in its face in the press through which the brick are run for the ,final, or re-pressing operation. The pressure required for forcing the material into these depressions and raising the buttons by such method has a tendency to break down the original texture and lower the rattler test of the brick, as well as decrease the wear resisting qualities thereof and shorten their life. Buttons so formed also are not uniform and the surface of the brick adjacent thereto is frequently uneven.
My invention consists in an improved method and means for forming said buttons, or projections on the brick, whereby such excessive pressure and consequent disadvantages are avoided, and an improved product produced, all as will be hereinafter more fully described and claimed.
Referring to the accompanying drawings, which are made a part-hereof and on which similar reference characters indicate similar parts,
Figure 1 is a view of a die such as I use in a repressing machine in the practice of my said invention, partly in. section and partly in elevation,
Fig. 2 a section through a finished brick,
Fig. 3 a plan view of that side of the brick having the buttons formed in accordance with my said invention,
Fig. 4. a view similar to Fig. 2 showing a modified form, and
Specification of Letters Patent.
Patented Aug. 24, 1920.
Serial No. 879,518.
Fig. 5 a view similar to Fig. 3, showing a plan of said modified form.
The moving die A is formed with a slight depression and in its face where each button is to be formed and the depression is sur rounded with a tapered rim, or cup, a which projects somewhat beyond the face of the die and in operation becomes embedded in the body of the brick B iefore the face of the die begins to operate thereon, and being formed with a tapered edge forces up the material within, shaping and forming the button I) easily and uniformly. Such a rim is forced into the body of said brick without subjecting it to heavy pressure and not only draws out the button but forms a recess around the button, insuring an even surface adjacent to the button, and a uniform projection thereof, all of which features are an improvement over the common form of brick made by the usual method.
The brick shown in Figs. 4 and 5 is produced by the same method and the same means except that the button or projection instead of being round is rectangular, or oblong, which shape may be used, if preferred, or any other shape desired.
IIaving thus fully described my said invention, what I claim as new and desire to secure by Letters Patent is:
1. A paving brick having projections on its side with each projection surrounded by a recess extending into the body of the brick at the base. substantially as set forth.
2. The method of forming paving brick with proj ctions on the side which consists in first forming the brick and then subjecting them to a re-pressing operation under a die having depressions surrounded by projecting cup-shaped rims, substantially as set forth.
In witness whereof I have here hereunto set my hand and seal at Indianapolis, Marion county, Indiana, this 7th day of December, A. D. nineteen hundred and fourteen.
