UNITED STATES PATENT OFFICE.
CHARLES WEsLEY BURROUGIHS, E MONTREAL, QUEBEC, CANADA.
FURNACE ARCH.
i Application filed December 24, 1924. Serial lie. 757,85i5. i
To all whom it may concern:
Be it known that 1, CHARLES WESLEY BUR- noucrrs, a subject of the King of Great Britain, and residing at Montreal, in the Province of Quebec, Dominion of Canada,
have invented certain new and useful Ini- .provements in Furnace Arches, of which the following is a specification.
Thisinvention relates to furnace construction and more particularly to suspended arches employed in boiler furnaces.
The object of my invention is to provide a simple, strong and cheap form of fire brick and a ready means of suspending and adjusting one or more of a series in position.
A further object is to provide a means of suspension that will not become overheated.
A" further object is to provide means for removing one brick of a series and replacing the same without disturbing or affecting the adjacent bricks.
Reference is made to the accompanying drawings in which Fig. 1 is a front view of a series of fire bricks suspended to form an arch.
Fig. 2 shows the form of a single fire brick.
Fig. 3 shows the wedge.
' Fig. 4 is a perspective view of the means of suspension.
In the construction of the furnace setting to which my invention is to be applied, 1 provide a series of parallel longitudinal. I beams 1, in the roof of the tire box.
The fire brick 2 is rectangular in shape of suitable thickness with an inverted wedge shaped groove 21, moulded to run from the front to the back and parallel with the sides.
The opening of the groove is made slightly wider than the width of the I beam flange 10, to allow the brick to be raised into posi tion about thelower flange 10, of the I beam 1.
Metal wedges 3 are then fitted on their side of the groove with their flat edges against the inclined sides of the roove and their rounded edges against the edges of the flange of the I beam.
By this means each fire brick composing the arch is adjusted and held in position.
It can be readilyremoved by loosening the wedges. I I
The I beams dofnot contact with the fire bricks, and ample "circulation of air through the groove prevents overheating.
The upper parts of the fire bricks are designed to provide great strength and durability, the setting and removal of a brick not injuring it in any way.
lVhat I claimis:
1. In a suspended arch furnace setting, a series of longitudinal I beams on trie roof of the fire box, and rectangular fire bricks with central upwardly diminishing grooves in their upper ends and wedges to secure the I beams in the grooves.
52. In a suspended arch furnace setting a rectangular fire brick having a central upwardly diminishing groove in its upper end and removable means to secure it to the roof of the fire box. j
8. In a suspended arch furnace setting, a series of rectangular fire bricks having central upwardly diminishing grooves in their upper ends, a series of parallel I beams in the roof of the fire box and wedges to secure the fire bricks to the I beams.
4:- In a suspended arch furnace setting the combination of a rectangular fire brick having a central upwardly diminishing groove in its upper end, with wedges adapted to secure the brick to the roof of the fire box.
5. In a suspended arch furnace settii'ig, the combination of a rectangular fire brick having a central upwardly diminishing groove in its upper end, adapted to provide an air channel, and an I beam suspended in the roof of the fire box, adapted to enter the groove, with wedges to secure the brick to the I beam, interposed to prevent contact.
'6. In a suspended arch furnace setting, the combination of arectangular fire brick with a central longitudinal recess expanding downwardly in its upper end, with wedges adapted tosecure the brick to the roof of the fire box and to permit the downward removal of the brick.
