G RATEl BAR.
SPECIFICATION forming part of Letters Patent No. 378,195, dated February 21, 1888.
Application filed June 23, 1387. Serial No. 242,211. (Model.)
To all whom it may concern.-
Be it known that I, Isaac NEWTON DronrNsoN, of Reading, county of Berks, and State of Pennsylvania, have invented an Improvenient in Grate-Bars, of which the following is a specification.
My invention has reference to grate-bars; and it consists incertain improvements, all of which are fully set forth in the following speci 1o iieation and shown in the accompanying drawings, which form part thereof.
rlhe object of my invention is to so form a grate-bar that when in use the aineurrents will be properly guided upward to the re, the
I5 draft being automatically equalized over the entire surface of the grate-bar.
My object is also to so form the bar that the strains due to expansion and contraction will be equalized, avoiding warping and insuring 2o long service.
In addition to the above my object is to obtain a large area for the admission of air through the grate.
In carrying out my invention I form the grate-bar with two longitudinal parallel side webs having a series of oblique cross-webs cast between them, and between which are the air-passages in the top of the bar, which are made rectangular or parallelogrammic in area, v
3c and made oblique, as in the caseof the crosswebs. The sides of the bar have lugs, which prevent the next or adjacent har being placed so close as to prevent the free passage of air. The longitudinal webs are desirably made serpentine to allow the ready equaliziug of the air-currents under all of the bars.
In the drawings, Figure l is a plan view of agratc-loar embodying my invention. Fig. 2 is a side elevation of same with part in section,
4o and Fig. 3 is a cross-section online may.
A is the upper or body part of the grate-bar, and is made ila-t upon the top and perforated by holes or air-passages D, made oblong, rectangular, or parallelogrammic, so as to give a .i5 large area. The bar ais made very wide, so that but a few bars are required to a large furnace, and are therefore easily kept clean. Thebars are provided with the two longitudinal side webs, I3 B, which extend downward to 5o strengthen them.
O are downwardly-extending crosswebs cast solid with the side webs, B, and are arranged at an angle, so as to form oblique divisions, the lower ends pointing toward the front of the furnace, so as to catch incoming drafts of air and direct them upward. The openings D in the grate'bars are also oblique, corresponding with the webs G, and the lower parts thereof at d are made wider than vthe top, so as to allow any ashes, cinders, die., which may 6o enter at the top to fall freely out at the bottom. The webs G are of substantiall y the same depth, and the side webs, B, are preferably notched, as at b, between the webs Gfso as to allow a lateral circulation of any excess of air which may pass under a grate-bar, and thus supply another bar with an equal draft.
The peculiar construction here set out will prevent warping of the bar,as the strains will be equally distributed over it. The great 7o depth possible in the upper or body portion of the bar enables the casting between the airpassages D to be very thin, and thus increase the proportional airarea when compared to the solid portion, and by the depth of these divisions in the body portion the air-currents are readily guided upward, as in the case of the webs C.
The sides ofthe bars are provided with lugs E, which prevent two adjacentbars coming in So close contact, (see dotted lines, Fig. 1,) and thus insure intermediate air passages, and these lugs E are also made oblique, so as to direct the air upward, as in the ease of the webs C. 8 5
It is evident that the details may be somewhat modiiied without departing from niyinvention.
Having now described my invention.l what I claim as new, and desire to secure by Letters 9o Patent, is-
1. A grate-bar wherein there are two deep side webs parallel to each other, having cast thereto a series of shallow oblique eross-webs, forming air-spaces which are rectangular pan allelogram in form and increase in area as they are removed from the surface of the bar, and deep cross-webs arranged at intervals apart and including between two such deep cross-webs a series of shallow cross-webs, the rco Said deep @hl-ida@ webs harige thsamdir-Qe tion of oblqitf the 'hhlowveb'sed ex'- tending considerably below' said shallow webs.
