in brickwork with other standard frebrick;
shapes without any alteration or special handling. Another object is to secure an offsetting or staggering of the jointsbetween the bricks in one course with relation to the joints between the bricks in the contiguous courses. Other objects are to permit the removal and replacement of bricks located between adjacent framing members of the furnace without disturbing any other bricks.
The invention consists in the improved fire bricks and in the manner of attaching such bricks to the framework of the furnace to form a `brick lining therefor. l. It also con'- sists in the parts and in the arrangements i and combinations of parts hereinafter describedand claimed.
In the accompanying drawing, whichv forms part of this specification and wherein like symbols refer to like parts whereverA through the side framing members of the furnace showing a lining embodying my invention attached thereto. A
Referring tothe accompanying drawing, my invention is shown in connection with the metal framework-at the top or sides of a furnace. As shown in drawing, said framework comprises spaced parallel framing members preferably inthe /form of bulb beams 5 disposed with their webs vertical. This construction of furnace framework is well known and it is considered unnecessary to illustrate it in detail.
Attached to the'bulb beams 5 of the framework of the furnace is a lining 6 comprising two sets of refractory bricks A and B the bricks being of substantially the same weight and size as a standard firebrick. The bricks of the kind A are provided at one side adjacent to one corner with a relatively shallow V-shaped groove or notch 7; and the bricks of the kind B are provided at one side adjacent to one corner with a relatively deep V-shaped groove or notch 8.
As shown in the drawing, the bricks are laid in courses, each course extending transversely of the bulb-shaped framing members 5 at the top or sides f f lthe furnace and comprising bricks of th lkind A alternating with bricks of the `ind B, Said bricks are arranged with tlxcir length transverse to the framing members 5 of the metal framework of the furnace and with their body portions extending inwardly beyond the lateral'side flanges of said framing members to from the refracto yv brickwork l" iing 6 therefor.
Each course or row of brick has two bricks, o ne brick of the kind A and one brick of the kind B disposed between adjacent framing members; and said bricks are arranged with the shallow notch of the brick A in engagement with the adjacent flange of one framing member and with the deep notch of the brick Bin engagement with the adjacent flange' of the other framing member. With this arrangement of the notched bricks A and 13, the main body portion of the bricks overlap or cover the bulb iianges of the framing members, and
.the different depths of the notches therein bring about an osetting of the joints in adjacent courses along the center lines, of the bulb beams and lines' passing midway therebetween. The advantage of this staggering.
or breaking of the joints in adjacent courses on opposite sides-of the center lines of the framing members, is that it tendsl to vprevent cracking of the lining along said members and thus expose them to theaction of fire. v
As shown in Figures 1 and 2 of the drawing, the bricks, when suspended from the lower anges of the bulb beams at the top of the furnace, tend to pivot or rock on the supporting flanges of said beams and thus bring the corners of the bricks into abutting relation at diagonally opposite corners, thereby forming V-shaped joints between adjacent bricks. As shown in the drawing the joints at the bulb beams are narrowest at the inner ends of the bricks and gradually widen towards the notches; and the joints located between the bulb members are narrowest at the outer ends of the bricks and gradually increase in width at the inner ends thereof. By the arrangement just de- 'scribed the bricks are suspended from the bulb beams adjacent to one cornerjwith every brick in a row touching the bricks adjacent thereto at diagonally opposite corners with the result that the brickwork lining structure acts after the manner of an accordion, being continuously sealed against air and, at the same time, permitting each individual brick to expand or contract and thus accommodate itself automatically to temperature changes. As shown in the drawing, the corners of the bricks are preferably coped olf or beveled, as at 10, adjacent to their notched portions so as to provide a proper clearance between said corners and the ends of the supporting beams during the pivoting orv rocking of the bricks on the supporting flanges of said beams.
Obviously, the hereinbefore described construction admits of considerable modification without departin from the invention, and I do not wish to limited to the precise construction shown.
What I claim is:
l. A furnace lining comprising spaced parallel frame members, bricks of substantially standard tire-brick dimensions arranged in courses extending transversely of said frame members, said bricks being arranged in pairs between adjoining frame members and having notched sides adapted to engage said frame members, the bricks of each pair having notches of different depths, and thel bricks being so engaged with the frame members that the shallower-notched bricks alternate with the deeper-notched bricks in directions longitudinal and transverse of the frame members.
2. A furnace liningI comprising spaced parallel frame members, bricks of substantially the same cross-sectional size and sha e arranged in courses extending transverse y of said members, said bricks being arranged in pairs between adjoining frame members and the bricks of each palr having notches in one side thereof adapted to engage said frame members, the notches in the bricks 4' of each pair being of different depths, and
the bricks beingso engaged with said frame members that the joints in one course are offset or staggered with relation to those in the contiguous courses.
3. A furnace lining comprising spaced parallel frame members having fijanges at each side thereof, bricks arranged in courses extending transversely of said frame members, said bricks being arranged in pairs with the inner ends of a pair disposed between adjoining frame members and provided with notches adapted to engage the flanges of said frame members,.the bricks of each pair having notches of different depths, and the bricks being so engaged with the flanges of said frame members that the joints between the bricks in one course are offset with relation to the joints between the bricks in the courses adjacent thereto.
4. A furnace lining comprising spaced parallel supporting members provided with lateral anges, bricks disposed in courses extending transversely of said supporting members with their end portions extending therebetween, the portions of the bricks located between said supporting members being provided with notches adapted to engage the flanges thereof, and the portions of the bricks located beyond said framing members being of the same cross-sectional size and shape, the notches in some of the bricks being relatively deep, and the notches in the other of said bricks being relatively shallow, the bricks being so mounted on the supporting members vthat the bricks having the shallow notches alternate with those having the deep notches both longitudinally and transversely of the supporting members, whereby the joints between the bricks in one course are offset with relation to the joints between the bricks in the courses adjacent thereto.
5. A building unit for brickwork, said unit comprising two bricks of substantially the same dimensions, each of said4 bricks having a groove in one side, the groove in one of said bricks being of greater depth than the groove in the other of said bricks, as and for the purpose described.
6. A furnace lining com rising spaced parallel frame members, bric s arranged in courses extending transversely of said members,` said bricks vbeing arranged in pairs between adjoining frame members, and having notched sides adapted to engage said frame members, vthe bricks of each pair having notches of different depths, and the bricks being so mounted on the frame members that the spaces between `the bricks in one course are offset with relation to those in the contiguous courses and the space at one side of a brick in a course tapers in one direction and the space at the opposite side of said brick tapers in a reverse direction.
7. A furnace lining comprising parallel spaced horizontal framing membeirs provided with lateral flanges, bricks disposed in courses extending transversely of said members with their upper ends disposed therebetween, each of said bricks being provided adjacent to one of its upper corners with a notch adapted to engage the lateral course at its diagonally opposite corners.
