Description

EARL V. WAGNER,0F SCRANTON, PENNSYLVANIA, ASSIGNOR TO THE WAGNER FIRE BRICK COMPANY, OF HELENA, MONTANA.

COMPOSITION OF MATTER FOR MAKING FIRE-BRICK.

No Drawing.

To all whom it may concern:

Be it known that I, EARL V. WAGNER, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented a new and useful Composition of Matter for Male ing Fire-Brick, of which the following is a specification.

My composition consists of the following named ingredients combined. in substantially the proportions here stated:

Coal ash 100 lbs. Magnesia 3 lbs. Water 2 to 29,; gals.

It is not intended to confine the patent here applied for to the use of the ingredients specified in the proportions stated, as the proportions may in some cases be advantageously varied, producing substantial identity of result. To illustrate: If the fusion point of the coal ash is found to be less than 2600 degrees Fahrenheit, or if a high fusion point for the fire brick is desired, the percentage of magnesia used is to be increased. Thus, taking 100 pounds of coal ash as a basis whose fusion point is 2600 degrees Fahrenheit, to this is added 3 pounds of magnesia which will raise the fusion point of the mixture to 3250 (32253275) degrees Fahrenheit. If on account of impurities and foreign substances in the coal ash its fusion point is found to be below 2600 degrees Fahrenheit, the percentage of magnesia: must be correspondingly increased to produce the above named result, the percentages being based upon the original fusion point of the coal ash and upon the fusion point of the fire brick which it is desired to obtain. ,The proportions Specification of Letters Patent.

Patented Sept. 12, was.

Application filed January 8, 1916. Serial No. 70,983.

above stated are therefore approximately pure coal ash having a fusion point of approximately 2600 degrees Fahrenheit.

Grind and mingle the coal ash with the magnesia, then add the water and mix until thoroughly plastic. Press the plastic mass through a molding machine of approved type. Cut the brick to the size desired by the use of a cutting machine of approved type. The freshly cut bri'cks'are then repressed in a repressing machine of approved type in which they aresubjected to heavy pressure sufiicient to fill out all angles and I decrease the laminations and to strengthen the bond. Then place the brick in a closed drying oven and dry for six to eight hours at a temperature of 500-600 degrees Fahrenheit. Remove the bricks while hot to a closed burning kiln whose temperature is gradually raised to 2200-2400 degrees Fahrenheit at which temperature the bricks are fired for seven to eight days when they are allowed to 'cool gradually, resulting in the finished product.

I am not aware that the ingredients aforesaid, in the proportions stated, -or in any' tially as described.

EARL v. WAGNER.
