i dui-tai $131125 THOMAS-'S. DAVIS, OF LANCASTER, PENNSYLVANIA.
.Letters Patent N .-100,016, dated February 22, 1870.
IMPROVEMENT 51N @RATE-BARS.
The Schedule referred to in these Letters I-Patent and making part of the same.
To all whom it may concern Be it known that I, THOMAS SQDAVIS, of Lancaster, in the county of Iiauc'aster, and State of Pennsylvania, have invented and made a new and useful lmprovexnent in Grate-Bars for Furnaces and I do hereby declare the following to be a full, clear, and exact description of the said invention, reference being had to the annexed drawing making part of this specification, wherein- Figure 1 is a plan of the said grate-bar;
Figure 2 is a side View ofthe same; and
liigure 3 is a cross-section of thefsame at the line I I.
Similar parts are denoted by the same letters.
The object ot this invention is to give a large vextent of air-space for the passage of draught to the tire,-
. and to secure uninmity in the distribution of the air over the entire surface, and atthe same time present a nearly tlat upper stirring the fire.
My invention consists in a grate-bar formed with a longitudinal bearer, having a V-shaped upper edge to shed offthe ashes, combined with short hars running transversely ot said bearer at suitable distances apart, and having dat upper surfaces, the whole being tbrmed of one piece of cast-iron, and the ends of the grate-bar are strengthened by side connections.
By this construction, the proper surface is formed by the bars for the slice to rest upon in stirring the tire.
In the drawinga represents the longitudinal bearer formed sectionally, as seen in tig. 3.
surface for the poker or slice inA Upon this the cross-bars b b are supported, said cross-bars being flat on their upper sides, and at such a 'distance apartthat the fuel will not fall through, and said cross-bars and bearer are cast together, the surfaces of the bars b b' being above the V'top of .the bearer a. i
At the ends of the bar the longitudinal hars c c run from the cross-bar d to the end bearing piece e, and the bearer a extends up bet-Ween these bars c c, and unites with the bars d and e. f
'I introduce connecting V-shaped bars i, between the bea-rer a and bars c c, to strengthen said bars.
Iv am aware that grate-bars have been made with a longitudinal bearer, having cross-piecesf of a heartshape proj eeting above such bearer, but the same form a rough lire-surface, with nothing to support the poker or slioeJ I claim as my invention- 1.' The grate-bar formed of the longitudinal bearer, having-a. V-shaped upper edge, and with the transverse bars b l, the upper surfaces of which are flat or nearly so, and are above the upper edge ofthe bearer a, as set forth. v
2. The grate-bar formed bycombining the bearer a, cross-bars b, longitudinal bars e c, and transversel bars d e i, as and for the purposes set forth.
In witness whereof I have hereunto set my signaturethis 10th day of September, 1860.
THOMAS S. DAVIS.
