REFRACTORY ARCH AND ARCH BRICK V Filed Nov. 1a, 1926 2 Sheets-Sheet '2 ATTORNEY-5 Patented Oct. 7, 1 930 UNITED STATES ALFRED n. WILLETT, or wnsrniverinwoo a plication filed November 16,"iezepffseri inl148,69? F This invention relates to refractory arches a and arch brick, and particularly to locomotive arch brick construction, and has,as one other advantages as are incident to the invention, or whichmay occur to A in the art, are obtained, will appear from the preferred emy of its primary objects, the strengthening of 5 a the arch and the brick thereof. a
Another objectof the nvention is to minimize arch brick breakage and cracking, and
to reduce the likelihood of bricks falling into thefire even when cracked.
. How the foregoing, together with such those skilled following description of the bodiment of my invention, reference being had to the accomp anylng dr awings, wherein Fig.1 is a vertical longitudinal section through a locomotive firebox and arch embodylngmy improvements;
side brick in position between an arch tube Fig. 2 is a sectiontaken on of Fig. 15
Fig. 31s a side elevation of my improved the line 2- -2 and a side sheet of the firebox 'Fig. 1 is'a bottom plan view of the brick;
and y 1 Fig.5 is a cross section of one of the middle brick employed in the arch, and, the tubes on legs 4,
s51 courses of upwardly 10, such as the brick illustrated in Fig. '5,
having its greatest thickness at thecenter of .its span where the greatest stress and erosion occur, with depressions .11, 11 at either side of its crown and strengthening ribs 12, 12, and provided at the ends with tube-en-. gaging portions 13, 14, the latter of which permits the brickto adapt itself to variations in the spacing between tubes.
Referring now more particularly-to Figs. 3

What I claim is 1. A locomotive arch side-brick compris inga body arched upwardly from end to end, with its lower endthicker than itsupper end and having a pair of laterally-spaced apart tube engagingsockets on the lower the upper end'being tapered off to the tip on its under face midway of the brick sides to provide a sloping surface for sliding engagement with a side sheet and being cut back laterally on each side of said surface.
, 2. A locomotive arch side-brick comprising a body arched upwardly from end to end, with its lower end thicker than its upper end and having a pair of laterally-spacedapart tube engaging sockets on the lower end face, theupper end being tapered off to the tip on its under face midway of the brick sides to provide a sloping surface for sliding engagement with a side sheet and being cut back laterally on each side of said surface, said body having a depression midway of its sides on its under face, providing thrust-can rying ribs extending lengthwise at each side on the under face and a transverse rib extending from socket to socket.
3. In combination with a firebox side sheet and a substantially longitudinally extending water-circulation member, a refractory arch including a side arch-brick sloping steeply upward from said member to said sheet, said brick having a runnerlike surface on the under face at the upper end midway of the sides slidably engaging said sheet, and a pair of laterally-spaced-apart sockets in its lower end face rotatively engaging said memher, the body of the brick being arched up wardly from end to end, substantially uniformly, to carry the weight thrust, endwise of the brick, downwardly to said member.
In testimony whereof, I have hereunto signed my name.
