01 PITTSBURGH, AND WILLIAM LEHMAN, OF ASPINWALII, PEN q SYLVAN'IA; SAID LEH'MLAN ASSIGNOB OF HIS ENTIRE RIGET TO WILLIAM 1r: it F PITTSBURGH, PENNSYLVANIA.
' cnncxna BRICK.
Application filed September 2d, 1928. Serial N0. 685,413.
To all whom it may concern:
Be it known that we, JosEPH Hoesm and. WILLrAM LEHMAN, both citizens of the United States, residing at Pittsburgh and 5 Asplinwall, respectively, in the county of Alleg eny and State of Pennsylvania, have invented new and useful Improvements in Checker Bricks, of which the following is a specification. v
This invention relates to bricks, and more particularly to what we term a checker brick particularly adapted for use in constructing checkers in furnaces and similar structures.
One of the main objects of the invention is to provide a brick which is movably. supported so that, duringthe use of a checker,./ these bricks will be caused to move slightly so as to prevent the accumulation of dust,
soot, ashes and other foreign materials to such an extent as to clog the checker. A further object is to provide a brick of this construction which may be readily produced and installed at small cost. Further ob- 26 jectswill appear from'the detail description.
Inthedrawings: Figure 1 is a fragmentary to plan. .view of a checker structure showing t e bricks as Figure 2 is a side view of the movable brick;
Figure 3 is a side viewof one of the supporting bricks;
Figure 4' 's a fragmentary side view of a chegker structure showing the bricks as use F We provide two different constructions or types of bricks, one of these, designated by numeral l'being what we term the supporting brick and being provided, at the center of the upper portion of each side, with a re-' cess 2. Recess 2 is adapted for reception of a gudgeon 3 provided at the upper portion of the end of a movable brick 4. In. 'racv tice'twoof the supporting bricks'l an one of the movable bricks 4 ma be considered as constituting a set. Brio 4 is rockably su ported between bricks 1 so as to be movm. ab e about an axis extending at right angles tothmsupportirig bricks. Thechecker 1s builtup' m a known manner, supporting bricks 1 being laid in tiers or courses, the
cally extending groove 1 and at the other end with a vertically extending tongue 1",.
the bricks of each course being locked together by these tongues and grooves. As each course of supporting bricks 1 of two adjacent .walls is completed, the movable bricks 4 are positioned between the courses with gudgeons 3 resting in recesses 2, the bricks 1 of each course serving to prevent displacement of the gudgeons 3 from the recesses 2 of the lower course. As the bricks 1 of each course are staggered relative to the bricks of the next course, the rockable bricks 4 of each course will also be staggered relative to the rockable bricks of the next course. The lower edge of each brick 4 is rounded at 4 so as to rovide a smooth rounded surface upon which dust and other foreign materials will not readily settle.
When the checker is in use the draft flow-.
ing through the checker and about bricks 4:, combined with vibration incident to the operation of the furnace in connection with which the checker is used, will cause a slight swinging or swaying movement of bricks 4 prevent accumulation of the same within the checker, the materials thus dislod ed collecting in-the lower portion of the chec er chamber from which they may be readily re to dislodge all soot, dust and other. foreign m'ateriaLs, to such an" extent as to ers rockably spfiported in spaced relation between said w 3. In achecker W0 malt sup rting walls formed 0f bricks provided in t eir lateral faces with recesses and cross bricks-provided with gudgeons iitting into said recesses and rockably supporting said 5 cross bricks'between the bricks of the walls.
4. As an article of manufacture,- a. checker brick provided at each end with a. gudgeon of circular cross-section adapted to fit intn a corresponding recess provided in the lateral face of a supporting brick. I
i In testimony whereof we afiix our signa- .tures.
