LOUIS PEELLAERT, OF ANTIVERP, BELGIUM.
FIRE-BAR FOR BOILER OR OTHER FURNACES.
SPECIFICATION forming part of Letters Patent No. 615,041, dated November 29, 1898. Application filed September 1, 1897. Serial. No. 650,229. (No model.)
To all whom it may concern:
Be it known that I, LoUIs PEELLAERT, a subject of the King of Belgium, residing at Antwerp, in the Kingdom of Belgium, have invented certain new and useful Improvements in Fire-Bars for Boiler or other Furnaces and Grates, of which the following is a specification.
My invention relates to fuel-supports for boiler and other furnaces; and it has reference particularly to the construction of the individual fire-bars comprised in said support.
The object of my invention is to provide a fuel-support the bars of which are formed and arranged so as to be free for longitudinal expansion and contraction, but not free to warp to a material degree, and so as to be individually and readily removable, the said form and arrangement of the bars being at the same time such as not to interfere with the supply of air admitted between said bars to the fuel.
My invention is fully illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of one of the fire-bars of my improved fuel-support. Figs. 2 and 3 are top and bottom elevations, respectively, of said fire-bar. Figs. 4 and 5 are vertical sectional views of one of the firebars, taken on the lines at x, y g, respectively, of Figs 7 and 6, respectively; and Figs. 6, 7, and 8 are sectional top and bottom plan views, respectively, of a portion of the fuelsupport.
The letters of reference on the drawings indicate parts correspondingly referred to in this specification.
In said drawings the fuel-support is shown as composed of a series of (preferably three) string-pieces O B C and fire-bars A, alternately arranged on said string-pieces, with their outer ends on the outer string-pieces C and their inner or adjacent ends on the central string-piece B, so that a bar on one side of the central string-piece is opposite a space between two bars on the other side of said string-piece. Each bar is provided with a spacing means at its outer end which consists of a portion D of the extreme end of the bar that is rebent upon and lies squarely against the surface of the side of the bar.
In order that the positive seating of the bars on the string-pieces may be the better insured, a rectangular portion is removed from the under side of each bar at each end thereof. By this arrangement, though the bars are of limited thickness they are steadily seated on their string-pieces, because a large portion of their weight is placed below the line of support. The bars are furthermore secured against warpingand also against longitudinal movement at their outer ends by means of arib E, situated upon the upper face of each of the side string-pieces and e11- gaging a correspondingly-shaped groove cut in the portion of the under face of each bar, that rests upon a string-piece and that is thickened by the part D.
In cross-section each bar converges from its upper to its lower edge, only one side or face of the bar, however, being situated at an acute angle to the plane of the tops of the bars, the other side being perpendicular or approximately so.
Substantially midway its length, but somewhat nearer one of its ends, each of the firebars is provided with an integral hollow rib projecting sufiiciently from the inclined side of the bar to span the adjoining space and abut against the adjacent bar in the complete fuel-support. In said complete fuel-support alternate bars are arranged with their ribs nearer their outer ends.
The rib a is formed in casting the bar by deflecting an elongated portion of said bar, that extends from the bottom thereof toward but not to its upper edge or surface, out of the general plane of the body of said bar. From its lower end this rib extends in crosssection vertically to a point substantially midway the depth of the bar, the contact portion of its outer surface being therefore parallel to the vertical face of the bar as well as to the vertical face of the adjoining bar. In side elevation this rib appears as being arranged obliquely to the upper and lower edges of the bar; but this arrangement, however desirable, is not essential. The rib does not terminate abruptly at its upper end, but inclines or tapers gradually off to the general plane of the bar. The bars are of course all mounted in position with their ribs projecting in the same direction.
In view of the foregoing it will be seen that the bars of my improved fuel-support are so formed that when they are in their proper positions they cannot be displaced in the operation of stoking or clearing the grate, nor warped to a material extent from the heat. 1 urthermore, notwithstanding their spacing means and the fact that their side faces converge toward their lower edges, the bars may be individually removed when necessary. This is because each bar is so shaped and its spacing means so formed and situated that although the spacing means projects far enough to abut against the face of the adjoining bar said spacing means does not project beyond the area of the bar as delineated by its top surface. It is obvious that were both faces of the bar convergent with respect to its generalplane the spacing means would necessarily have to project beyond the area of the top surface of the bar and would therefore prevent its ready individual removal.
The peculiar construction, position, and arrangement of the spacing means comprised in the rib (t which I have provided for each bar moreover affords opportunity for the bar to uniformly expand or contract without the consequent warping, which without my peculiar spacing means is well known to be usually incidental to a bar that varies in thickness.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
1. A fire-bar tapering in cross-section from its upper to its lower edge and provided with a hollow rib situated midway its length and extending from the lower toward the upper edge of said bar, said rib being formed by deflecting a portion of the bar out of the general plane of said bar, substantially as described.
2. A lire-bar tapering in cross-section from its upper to its lower edge and provided with a hollow rib situated midway its length and extending and tapering from the lower toward the upper edge of said bar, said rib being formed by deflecting a portion of the bar out of the general plane of said bar, substantially as described.
In testimony whereof I have set my hand in the presence of the two undersigned witnesses.
LOITIS PEELLAER'I.
