GRATE FOR FURNACES.
SPECIFICATION forming part of Letters Patent No. 398,950, dated March 5, 1889.
Application filed September 11, 1838. fierial lilo. 285,106. (No model.)
following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form part of this specification, in which Figure l is a plan view of a grate constructed in accordance with my invention. Fig. 2 is a sectional view of Fig. 1 on line a. Fig. 3 is a. detail sectional view of the same. Fig. i is a plan view showing a modified construction of grate. Fig. 5 is a similar view of a second modification.
This invention relates to stoves and furnaces, and its object is to provide improved sectional castings and grates therefor which will permit expansion or col'it-raction of the parts without danger of breakage; and the invention consists in the novel manner of lltting the sections together, and in certain novel details of construction hereinafter described, illustrated in the drawings, and concisely stated in the claims.
Referring to the accompanying drawings by letter, A designates a grate of ordinary form having an annular rim or frame and a series of cross-bars. The frame is formed in two equal sections, 1- C, as shown, the ends of which may be overlapped and jointed and z r l .lhe frame-secunited by securingholts Z) Z). tion B is provided with a series of bars, D D, of varying length, the ends of these bars being preferably reduced, as at d, and adapted to enter sockets or mortises E E. formed at corresponding points in the inner face of section C, so that when united, as described, the bars are properly supported at each end, but can expand or contract by heat without suhjecting themselves or the rim -secti t ns to ain.
As shown in Fig. from one section and all the mortises are in the opposite section. Preferably, however, I
5, all the bars project sockets of the opposite section when the seeeach section, as shown in Figs. 1 and 4. The bars in this instance alternate with the sock-- ets of their respective sections, and the bars of the two sections are so arranged that when the sections are united the bars will he alternately loosely con nccted to the sections at opposite ends.
Instead of uniting the sections at their ends by bolts 5 they may be united cent-rally, as shown in Fig. 4-, by means of the central grate-bar, P, which is enlarged and is united at one end to the center of section B, and its have both bars and sockets provided with other end is lapped in a corresponding recess in the center of section C and secured thereto by a. bolt. lif desired, both the central and end ifastenings may be used in the same grate.
The bars are of such length or so finished at their ends that when the frame-sections are properly united the free ends of the bars will not bind in their respective sockets, so that each bar may contract or cxpan d without disturbing the others.
I have illustrated a circular grate; but the essential idea of the invention is equally applicable to other forms of castings, and, if desired, the frames may be formed in more than two sections, the essential feature of the invention being the properly supporting the bars while allowing each bar to freely and independently expand or contract.
Having described my invention, I claim- 1. A grate composed of two frame-sections connected substantially as described, and a series of grate-bars, each one. of which is rigidly connected to or formed with one of the frame-sections at one end and has its free end loosely engaged in a corresponding socket in the opposite frame-section, whereby each bar can expand and contract independently of the other bars, substantially as described.
*2. The herein-dcserihed grate, composed of the frame-sections B and C, connected at their ends, and each provided with alternate gratehars and sockets, the ends of the bars of one section being arranged to enter loosely the tions are united, substantially as set forth.
3. The combination, in a grate, of the sec In testimony that I claim the foregoing as my own I affix my signature 1n presence of two Witnesses.
