UNITED STATES PATENT OFFICE.
HENRY TANNER, OF CHICAGO, ILLINOIS.
FIRE-BRICK.
Specification of Letters Patent.
Patented Dec. 21, 1915.
Application filed November 21, 1912. Serial No. 732,662.
To all whom it may concern:
Be it known that I, HENRY TANNER, a citizen of the United States of America, residing at the city of Chicago, in the county of Cook and.State of Illinois, have invented certain new and useful Improvements in Fire-Bricks, of which the following is a My invention relates to heating furnaces,
iand particularly to those having a flat ignition arch. These are generally used in connection with chain grates by which fuel is fed under steam boilers. A supporting framework is necessary to hold the fire brick in place, and the brick perform the double oflice of providing a closed flat roof or arch and of protecting the supporting framework from the otherwise destructive heat. Heretofore the brick have been supported by placing them in single or double rows between each two beams or supports, the latter being flanged to engage with grooves in the sides of the brick adjacent thereto. The joints between the bricks being thus alined with the supporting members 'form a point through which the heat readily penetrates to the support. This is especially true when the joints are not properly fitted or where, as is frequently the case, the intense heat causes an expansion and contraction which opens the joints between the brick. It has been sought to minimize this difficulty by providing the bricks with a horizontally placed tongue-andgrooved beading, but the protection is not complete.
By my invention the fire brick are centrally suspended on the supporting members completely surr unding the portions nearest the fire and protecting them from the disintegrating effects of the heat.
The principles of my invention are illustrated in the drawings, in which A in Figure 1 shows a perspective view of one of my improved tiles: B in Fig. 24s a modified form thereof; Figs. 3 and 4 are partial sections taken respectively on the lines 3-3 and H of Figs. 1 and 2; Fig. 5 is a partial section on the line 55 of Fig. 6; Fig. 6 is areduced representation of an arch support to illustrate the application of my improved brick thereto.
The brick shown in Fig. 1 has a transverse groove 1, which is undercut at 2, and adapted to receive the metallic arch support 4. The latter'has a transverse flange 5 on its lower edge, making it Tshaped in cross section to correspond to the form of the slot asshown.
modified form of the brick is shown in Fig. 2. The slot 1 is not extended through the entire thickness of the brick, but the undercut portion 2 is extended beyond the front portion of the slot, so that the ad-- vanced portion 5' of the hanger flanges will .seat within the pocket thus formed, fully protecting the advanced end of the hanger support.-
It will be seen that by using one or the other of the forms shown, the arch supports may becompletely protected, both as to the main body portion and as to an extended end or tip. The heat which may go between the bricks passes upward between the hangers without impinging upon them, thereby greatly increasing their life. The
extreme end of the hangers is protected by lower flanges of the beam projecting beyond I the web thereof, and end blocks having a centrally placed undercut groove, said groove being extended to form a pocket to.
receivethe said extended ends of the beam.
2. The combination with a furnace arch beam having its lower edges transversely extended to form flanges parallel with the body thereof, said flanges being extended from the end of said beam, of. afire brick having a centrally placed undercut'groove on its upper face adapted to take the flanges on said beams, the undercut portion being extended to form a pocket in the same hori zontal plane, said groove and pocket being adapted to receive the said flanges and the extended portion thereof.
3. The combination with a furnace arch I beam having a vertical web and a trans-' verse flange on its lower edge to form an inverted T in cross sectlon, the sald transverse flange having anadvancied portion projected beyond the end of the vertical flange, of a fire brick having a centrally placed undercut groove, said groove being extended to form a pocket to receive the said advanced portion of the horizontal flange.
4. The combination with a furnace arch beam having a vertical Web and a transverse flange on its lower edge to form an inverted T in cross section, the said transverse flange having an advanced portion projected beyond the end of the vertical flange, said arch beam being further provided with a removable tip having a vertical web and a transverse flange on its lower side to form an inverted T in cross section, the said transreceive the said advanced portions of the horizontal flanges.
In witness whereof, I have hereunto subscribed my name this llth day of November 1912, in the presence of two subscribing Witnesses.
