WILLIAM R. BRADFORD, OF CHARLESTOWN, MASSACHUSETTS.
Letters Pate-at No. 62,927, dated March 19, 1867.
IMPROVED COVER FOR KILNS 0F SUGAR REFINERS.
TO ALL WHOM IT MAY CONCERN:
Be it known that 1, WILLIAM R. BRADFORD, of Chariestown, in the county of Middlesex, and State of Massachusetts, have invented a combined Cast-Iron and Fire-Brick Kiln Cover for Sugar Refineries; and I do hereby declare that the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention, sufiicient to enable those skilled in the art to practise it.
The invention relates to means used for rendering more enduring the covers of kilns used in sugar refineries,
for burning charcoal or bone-black. In the common form of construction, these covers are made of cast iron, and direct impingement of the great heat to which they are subjected, and the weight of the covers, soon cause them to sag under the repeated heats of the furnace, from which sagging they are either destroyed or soon become too much impaired for use. To remedy this defect is the object of my invention, and I accomplish this object bycasting the metal to form the cover directly upon and around blocks of soap-stone or fire-brick, leaving the fire-brick exposed on the bottom side of the cover, or that surface against which the heat directly impinges. The non-heat conductivity of the stone prevents the metal from getting red hot, and thus 'preserves the cover, the metal being, of course, so cast around, or connected with, the stone, as to hold the stone securely thereto. It is in this construction that my invention consists, and the drawing represents a vertical section of a cover having such formation. l
The stone or fire-brick a, cut or moulded to proper thickness, has an inclination or dove-tailed formation at its opposite sides, as seen at 6. Around the top and edge'sof this fire-brick the metal is cast, as seen at c, and when so cast it will be obvious that the brick will be retained in position by its narrowing form, from its lower to its upper surface. The metal may be similarly cast around a series of bricks or blocks of stone, the A blocks being'arranged at a little distance apart, so that the metal shall flow between them and bind them all together, and rods may be extended througlrthe stone, connecting the vertical walls of the casting, and other modifications, as found desirable, or as circumstances require, maybe made, the essence of the invention, or the formation of the cover by casting the metal upon the stone, and so that the metal and stone shall be secured together, being retained. By this construction the heat from the red-hot charcoal is intercepted by the stone or lining of the metal cover, and the integrity of the cover is thereby preserved.
I claim the construction or formation ofa kiln cover by casting the metal upon a fire-brick or bricks, or other similar material, and so as to secure the metal and brick together, substantially as set forth.
WM. R. BRADFORD.
