GRATE.

SPECIFICATION forming part of Letters Patent No. 402,842, dated May '7, 1889.

Application filed December 13, 1888. Serial No. 293,418- (No model.)

T0 (0 whom, it may concern:

Be it known that I, HENRY C. KERSTINE, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Grates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in grates; and its objects are to form the front of the grate or basket from anumber of separate bars which are made U-shaped or provided with recesses in their under sides and to connect these bars together by headed rods which pass vertically down through the bars and the blocks which separate them; to form the front of the grate or basket of bars which have their ends turned outward so as to project horizontally beyond the central portion of the grate, and thus cause the ashes which may fall from between the bars to fall behind the screen which is placed upon the hearth, and thus keep the hearth always clean, and to provide the turned-out ends of the gratebars with flanges sufliciently wide to bring the ends of the bars in contact with each other, and thus prevent any ashes from falling outside of the screen at these points, as would otherwise would be the case.

Figure 1 is a front elevation of a grate which embodies my invention. Fig. 2 is a vertical section of the same. Fig. 3 is a plan view. Fig. 4 is also a vertical section of my grate, taken on the line to 0B of Fig. 1.

The front of the basket is composed of a number of separate bars, A, having the flanges B projecting from the lower edges, and which are bent or curved at their ends 0 and provided with the lips 0 upon their lower edges, as shown. These lips are made sufficiently wide to extend down to the bar below, and thus prevent the escape of any ashes at this point, and the ends of the bars are bent outward, as shown, so that any ashes which may fall from between the bars will fall inside of the. damper-screen G. These bars are provided with the flanges B for the purpose of strengthening the bars, to prevent them from warping, and to hold air in contact with their under sides, so as to prevent them from burning out as readily as they would do if they were formed of flat bars alone. These bars are separated from each other by suitably-shaped blocks II, the upper ends of which catch between the flanges B, and are thus prevented from turning upon the clamping-rods I, which bind the blocks and the bars rigidly together. These rods have suitable heads, J, cast upon them, and these heads catch against the upper surface of the top bar, while the lower ends of the rods are held by nuts, as shown. WVhere thebars are made perfectly straight or rounding from end to end, the ashes fall outside of the damper-screen and dirty the hearth. Where the ends are turned out and form a stop for the ends of the damper-screen, all the ashes will fall inside of the damperscreen and thus always keep the hearth clean.

Having thus described my invention, I claim' 1. The grate or basket front composed of the bars A, provided with the flanges B upon their lower edges, in combination with the headed rods and the blocks which separate the bars, substantially as set forth.

A grate or basket front composed of the bars A, provided with the flanges B upon their lower edges, and having their ends turned outward, as shown at O, and provided with the lips O at their turned-out ends, substantially as described.

3. A grate or basket front composed of the bars A, provided with the flanges B upon their lower edges, in combination with the rods which connect the bars together, and which bars are provided with the turned-out ends 0 and lips C, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.

HENRY O. KERSTINE.
