ARCH BRICK.y l
Application led February 18, 1920. Serial N0.,359,490..
To all 'whom t may concern: j
Be it known that I, JOHN H. DnMrsnY, a citizen of the United Stat-es, and a resident of the city of Cleveland, in the county of Cuyahoga and `State of Ohio, have invented a new andlmproved Arch Brick, of which the following is a full, clear, and exact description. v
This invention relates to improvements in arch bricks, an object of the invention being to provide a `refractory brick or tile which is supported upon the arch tubesv cfa boiler fire-box, to form an arch, to control or` direct the iiow of smoke and gases through the boiler. I. l.
A further ob]- ect iste provide an improved construction or shape of brick which cooperates with adjacent bricks to snugly iit the arch tubes and the side of the lire-box, which permit of easy adjustment without undue binding, and which embody structural strength by reason of the curved or arched shape of the respective bricks.
A further object is to provide an improved construction of brick which, when assembled on the arch tubes, present a smooth surface or wall to the re-boX side and each brick is curved or arched transversely on its outer face imparting the maximum of strength and durability thereto.
With these and other objects in View, the invention consists in certain novel features of construction and combinations or ar rangements of parts, as will be more fully hereinafter described and pointed out in the claims.
ln the accompanying drawings- Figure 1 is a view in longitudinal section of a locomotive with the improved bricks placed on the arch tubes therein.
Figure 2 is a fragmentary plan view of my improved brick arch.
Figure 3 isa view in section on the line 3-3 in Figure 2.
Figure 4 is a plan view of one of the bricks.
Figure 5 is a view in side elevation of Figure 4.
Figure 6 is a view in section on the line 6 6 of Figure 4.
Figure 7 is a View in section on the line 7*'7 of Figure 4 showing two bricks in position.
Figure 8 is a plan view illustrating a modied form of brick.
l represents a steam boiler of the locomotive type having a. tire-box 2 with arch tubes 3 extending longitudinally of the rebox as is customary in the art.
On these arch tubes 3 by improved bricks 4 are supported. The bricks 4 are of refractorymaterial and are commonly known in the art as blocks, tile, orbrick, and I shall use the term brick as a preferable term to define the device.
`Referring particularly to Figures 4, 5, 6 and 7, it will` bel noted that the brick 4 has a flat lower surface 5 and a curved or arched upper yface 6, the arch being `transversely or' the brick. The longitudinal edges of the brick are curved transversely as shown at 7 to conform to and to t the arch tubes 3, and these curved faces 7 permit the relatively sharp edges of the bricks to come together as shown in Figure 7, to prevent binding action and yet allow of flexibility of adjustment to properly position the bricks on the tubes. The curved edges 7 of the bricks 4 are in reality the inner surfaces of longitudinal grooves, so that the lower surfaces 5 of the bricks are positioned between the boiler tubes, and all ot' these surfaces 5 are in substantial alignment so that a smooth fiat surface is presented to the lire, while the upper surfaces of the bricks are arched as shown at 6 to give the maximum strength and durability tothe brick.
The brick 4 is provided centrally with an opening 8 and in its ends with recesses 9 series of openings in their longitudinal cenj ters, to .allow for the passage of smoke and gases through the arch. In the sides of the brick 4 curved recesses 10 are provided which permit a flow oi smoke and gases in contact with the tubes 3 as illustrated clearly in Figure 7. These recesses l0 may be staggered along the longitudinal edges of the bricks as indicated, or they may be otherwise arranged in accordance with the desire of the user. These several openings in the bricks not only allow gases to pass through but also serve the purpose of checkering or subdividing the swirling gasesin their passaoe.
At the sides oi' the iire-boX it is necessary to provide hair1 bricks ll which are formed by splitting the bricks 4 longitudinally, and it will be noted, particularly by reference to Figures 2 and 3, that these half bricks 11 fit snugly against the sides of the fire-box andh maintain the general` contour of the arc In the modification illustrated in Figure 8, I shov7 a longitudinalv series-of openings l2 in the brick 13, which in other respects is similar to the brick 4 above described'.v
The purpose of the holes in the tiles or bricks is to checker or mix more scientifically the uncombusted gases, smoke and air; also in this checkering operation in passing through the holes greatly increased radiation surface is passed over, which when the bricks are heated', accentuates the process of combustion.
It Will be noted if the smoke, gases, etc., merely passed over the flat inner side or face of the bricks when heated, there would be the loss of checkering mentioned in passing through the holes.
y Various slight changes may bev made in the general form and arrangement of parts described Without departing fromy the invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and dependent refractory bricks, said bricks having longitudinal grooves' receiving the arch tubes and resting thereon, said bricks having flat lower faces and transversely arched upper faces, said bricks having openings therein andv having recessed edges., Wherebypassages are provided through the bricks' for the smoke and gases .and the smoke and gases caused to contact with the boiler tubes, and half bricks located adjacent the Wallsl of the fire-box. JOHN H. DEMPSEY.
