GRATE.

SPECIFICATION forming part of Letters Patent No. 286,574, dated October 16, 1883.

Application tiled June 13, 1883. (No model.) l

To afZZ whom it may concern.-

Be it known that I, Jenn BALLOU, a citizen of the United States, residing in Somerville, county of Middlesex7 and State of Massachusetts, h ave invented anew and useful Improvement in Grates, of which the following is a speeication. y

My invention relates to certain improvements in that class of grates commonly used in cook-stoves or ranges.

The obli eet of my improvement is to provide a grate which affords facilities for keeping the ire in proper condition with an economical consumption of fuel, and it also allows the grate to expand and contract without undue strain upon any of its parts, all of which is explained more in detail inthe following specication and accompanyingv drawings.

In the drawings, Figure l is a plan or top viewer' the grate, and Fig. 2 is alongitudinal section through the center.

Similar letters refer to similar parts.

From the longitudinal bar a, which is the rear of the grate, a series of bars project parallel to each other and at right angles to the bar a, to the extreme front of the grate, with the usual spaces between the bars. The two outside barsf-one at each end-are provided with studs or bearings c e, by which the grate is supported in a manner so that it is nearly balanced, the rear being slightly heavier than the front part, and thus having a tendency to keep the grate in a level position when in use, and by which means the grate is permitted' to tilt in a manner common to grates of this class, one of the studs or bearings being adapted to receive a wrench or other suitable implement forthe purpose of tilting the grate when required. By this inode of construction the spaces between the bars at the front of the grate are open, each bar being free at the front end and independent of eachother, andinconsequence of this mode of construction the grate is permitted to expand and contract without causing a strain upon any part of it.v By this mode of construction, also, a poker or other suitable implement may be thrust under the grate and between the bars, and the fuel gently lifted, thus admitting the air necessary for Y grate, at their underneath side, are providedwith double longitudinal ribs; or, in other words, aregrooved out7 as shown in the sectional drawings, Fig. 2, thus allowing a free circulation of air around the bars, and obviating the tendency to warp. i y

The grate may be rectangular, square, or of any other shape, depending, of course, upon the style or shapeoi' the stove or range for which it may be specially designed.

I am aware that grates have been constructed in a manner so that the transverse bars were independent oi' each other at the front of the grate, and also that double ribbed or grooved bars have heretofore been used; hencel make no broad claim to these special features as distinct elements ci' my invention.

The combination, in a grate, of a longitudinal rear bar, `a series of double ribbed or grooved bars extending at right angles to the rear bar, and the studs or bearings e and c, located at or near the center of the outside bars, in the manner and for the purpose substantially as set forth.

y JOHN BALLO.
