GRATEI-BAR.
SPECIFICATION forming part of Letters Patent No. 737,156, dated August 25, 1903.
' I Application filed July 13, 1903. Serial No. 165,297. (No model.)
To all whom it may concern.-
Be it known that I, Orro SOHIMANSKY, a citizen of the United States, residing at Sandusky,-in the county of Erie and State of'Ohio, have invented certain new and useful Improvements in Grate-Bars, of which the following is a specification, reference being had therein to the accompanying drawings.
The invention relates particularly to hollow grate bars through which air-currents are adapted to pass to increase the combustion of the burning fuel; and it consists in the novel formation of the bar, and particularly in the peculiar construction of the capscovering the discharge-openings and their application to the bar, whereby a maximum airblast may be discharged within the arch and in all directions therein in such manner-as to produce intense combustion.
The invention further consists in certain details of construction, as will be hereinafter more fully set forth, and shown in the drawings, in which- Figure 1 is a broken plan view of a gratebar embodying my invention. Fig. 2 is a broken side elevation in longitudinal section. Fig. 3 is a perspective view of the bar. Fig.
" 4 is a cross-section taken on line 00 w of Figs.
1 and 2. Fig. 5 is a sectional perspective view of a portion of the bar,.showing the construction of one of the draft-openings. Fig. 6 is a perspective view of the cap. Fig. 7 is a sectional plan view of a modification. Fig,- 8 is a cross-section online y y of Fig. 7; and
Fig. 9 is an enlarged sectional perspective of.
a modified construction of bar, showing the discharge-opening.
The reference-letter A represents a gratebar ofany approved form and hollow, as illustrated. The bar is provided with a suitable air-inlet B and has formed in its top, which is flat, a plurality of discharge openings or outlets O. The walls about the dischargeopenings are provided with annular seats D, upon which the caps E are mounted. The
in various ways,
and projecta considerable distance within the grate-bar. These shanks serve a threefold purpose, acting, first, as weights to hold the-caps to their seats and prevent displacement upon shakingbr poking of the fire. Secondly, on account of the peculiar form of the sham k it serves as adeliector for the blast of air entering the hollow grate-bar from the inlet, causing the air to pass through all of a series of draft-passages hereinafter described arranged circum-ferentially about the cap. Thus a maximum amount of air is uniformly discharged within the usual arch which promotes combustion to such an extent as will permit'the burning of all kinds of refuse.
duces an annular space a between the cap.
and the walls of the opening. The air is discharged from the gratethrough the vertical openings b and the passage on If desired,
however, the cap-seats may be imperforate,
as shown in Fig. 8, and a series of spaced lugs or projections 0 formed thereon. The cap of relatively smaller size than the opening, as above set forth, rests in this instance upon the lugs, andthe air passes between the cap' and the seat and through the annular space a. The caps are also'preferably arranged within the openings below the Hat top a of the grate, so that a poker orscraper used in stirring the fire will not disturb them. It is immaterial, however, in whatparticular manner the circumferential draft -"passages are formed, providing the caps are provided with the conical deflectors described, which cause the air to be discharged uniformly through all of the circumferential passages for the purpose set forth. I do not desire to too be limited to the exact construction shown therefor, as the invention is susceptible of various modifications.
What I claim as my invention is 1. In combination with a hollow grate-bar having an air-inlet, and a discharge-opening formed in its top, of a removable cap seated within said discharge-opening and carrying depending from its under face an inverted conical shank projecting Within the bar, there being a series of draft-passages arranged circumferentially about the cap leading from the interior of the grate.
2. In combination with a hollow grate-bar, having an air-inlet, and a discharge-opening formed in its top, of a flat imperforate cap removably seated Within said discharge-opening below the grate-top and carrying depending from its under face an inverted conical deflecting-shank projecting within the bar,
there being a series of draft-passages arranged cireumferentially about the cap leading from the interior of the grate-section.
3. A hollow grate having an air-inlet and a plurality of discharge-openings formed in its top, the Walls about said openings being provided with flat annular seats, a plurality of spaced lugs upon each seat, flat caps seated Within the discharge openings below the grate-top of less area than the area of the openings, and resting upon the lugs 0n the seats, and an inverted conical shank integral with each cap and depending from the under face of the latter Within the grate-bar.
In testimony whereof I affix my signature in presence of two witnesses.
OTTO SCHIMANSKY.
