ARCH BRICK Filed Nov. 1927 Patented Apr. 9, 1929.
UNITED STATES PATENT OFFICE.

ARCH BRICK.
Application filed November 3, 1927. Serial No. 230,812.
My invention relates to refractory arches for locomotives and particularly to a novel brick adapted for use at a particular point in the arch.
In locomotives of a certain type, the circulating tubes or so-called arch tubes, are by reason of the design, located at their support ends at a point comparatively close to the grate; in other words, the throat sheet is shallow with the result that. the firing clearance between the bottom of the arch and the top of the grates is inadequate. Consequently the coal as it is thrown through the fire box door, strikes the arch, is deflected downward and forms a bank across the tire box at the throat sheet, leaving an intervening space between the throat sheet and the bank of coal which is not covered by fuehand through which cold air enters; or if the coal is not banked up at the forward end of the grate, the space at that point, the space next to the throat sheet, becomes filled solid with coal which eventually burns out leaving a mass of cinders and ashes at that point, the removal of which is dit'ficult.
The brick illustrated herein is designed to obviate this difliculty. It is of the common form so far, as the horizontally eXtending portion of the brick is concerned, but I have provided diagonally downwardly and forwardly extending marginal flanges suitably hollowed out or socket-ed to lit the tubes. li hen installed on the inclined arch tubes, the brick occupies a substantially horizontal plane, thus leaving a substantial clearance between the grate and the arch and avoiding the difficulties heretofore encountered.
The invention will be more readily understood by, reference to the accompanying drawings, in which,
Fig. 2 is a sectional view on the line 2-2 of Fig. 1;
Fig. 3 is a side view of one of the bricks;
Fig. 4: is an end view thereof; and
Fig. is a top plan view thereof.
In the drawings it will be seen that the side brick of my invention includes a body portion, 10 of generally arcuate form and tapered from the tube engaging side to the sheet engaging side. The end of the brick is notched at 11 to provide two points of support against the side sheet, thereby enabling the brick to adjust itself to variations in angle of inclination.
At the opposite side the brick is provided with a depending flange. 12 of progressively increasing depth from the back to the front thereof. -Along the lower outer marginal edge of the flange 1 provide a socket 13 for engagement with an arch tube, while interiorly of the flange I provide reinforcing material, 14.
The design of the brick is such that it may be easily molded and the deposition of the material is such that the brick is unlikely to be broken in handling.
In installation, as shown in the drawing, the body portion of the brick will remain in substantially the position it would assume if the circulation tubes were substantially horizontal, notwithstanding the fact that at the point of installation adjacent to the throat sheet, the tubes have an abrupt incline. Consequently the firing space adjacent to the throatsheet is materially increased. The arcuate form of the brick serves the useful function and this, together with the form of the side sheet, engaging end insures long life, notwithstanding removal at intervals for attention to the side sheet stay-bolts.
Various modifications may be made in the design herein illustrated, and I do not wish to be limited except as indicated in the appended claim.
I claim:
In a locomotive the box, the combination with the grate, circulation tubes and side sheet, of a side brick resting on a tube and leaning against a side sheet, said brick having a body portion and adepending flange of increasing depth from back to front and provided with a tube engaging socket adj acent to the lower margin of the flange.
In testimony whereof I have ailixed my signature.
JAMES T. ANTHONY.
