SPECIFICATION forming part of Letters Patent No. 459,948, dated September 22, 1891.
Application filed December 11, 1890. Serial No. 874.377. (No model.)
To all whom it may concern: make one of the projections a longer than Be it known that I, RANDALL A. PALMER, a the other projection a. Then, by reversing citizen of the United States, residing at Sagiend for end the alternate bars, it is manifest naw, county of Saginaw, State of Michigan, that the proper spacing is accomplished, as 5 have invented a certain new and useful Imshown in Fig. 1.

Fig. 2 is beneath to pass up around the end and so 15 a longitudinal section of the same. Fig. 3 is assist in effecting combustion clear to the a separate perspective view of one of the end of the grate-supports and at the same supporting-bars. Fig. 4 is a side elevation time keeping the grate-bars at a proper temof one of the grate-supporting bars, showing perature. The sections may, however, exa modification of my invention; and Fig. 5 tend clear to the extreme end of the support- 20 is a transverse sectional view of the grateing-bars, as shown in Fig. 4, in which event supporting bar exhibited by Figs. 1, 2, and 3. the portions a and a are dispensed with.
