UNITED STATES JAMES H. DWIGHT, OF ATLANTA, GEORGIA.

FIRE GBATE.

Application filed April 18, 1922.

To all whom t 'may concern.'

Be it known that I, JAMES H. DWIGHT, a resident of Atlanta, in the county of Fulton and State of Georgia, a citizen of the United States, have invented certain new and useful Improvements in Fire Grates, of which the following is a specification.

This invention relates to improvements in tire grates in which the various grate bars may be removed, and new ones replaced when one is broken or becomes burned out. These bars interlock into each other, maintaining a rigid construction as a whole. The front of the grate is constructed of one piece and is designed in an artistic manner. These grates are to be built in various sizes to suit modern constructed homes.

I attain these objects by the arrangements in the accompanying drawings, in which:

Figure 1 is an assembled grate.

Figure 2 the right hand starting bar.

Figure 3 a plan of a single bar.

Figure 4 a. side View of the starting bar and single bar, with a section thereof.

Similar numerals refer to similar parts throughout the several Views.

The front of the grate made in one piece at 1 is held in the frame of the tire place by lugs or ears 2. 3 are a series of slots cut along the front of the grate in which the bars fit. 4 vent openings in the front of the grate. 5 a hooked bottom in which the bars rest. 6 the starter bars are at each side of the grate, known as a right and left starter. 7 the single bars extending from the right starter to the left starter and interlocking at 8.

Figure 2, all parts have been formerly described by their numbers except 9 the lug which rests in the hook portion of the grate front at 5. 10 the front retainers which prevent the gratebars from falling, thus holding by pressure against the grate front the bars in place. 11 is the wedge which fits into the slot of the adjoining grate bar.

Figure 3, all parts have been formerly described by their numbers except, 12 which is a slot into which the wedge of the adjoining grate bar fits.

Figure 4, all parts have been formerly described by their numbers except, 13 which shows in dotted lines the grate front in position. The section shown in this figure is taken at cla-J) in Figure 3.

From the foregoin(T description taken in a A b o connection with the drawing the construe- Serial No. 554,384.

tion and relation of the parts comprising my grate will be readily understood, and it will be noted that according to my invention the grate comprises the front portion 1, made in a single piece or casting which is provided on the rear at each end near the top on its inner face with the pair of ears or hooks 2, which support the grate as a whole and this front portion is provided at its bottoni with the series of kerfs or recesses 3, which admit and interlock with the hooks or lugs 10, on the outer ends of the grate section while said front is further provided wit-h hooks 5 at each lower corner on the inner i ace which form` seats for the lugs 9, formed on the grate bars, said grate or supporting portion being composed of a series of end sections such as shown in Figure 1, and a series of intermediate bars or' sections such as shown in Figure 2, the sections and bars beingl provided at their inner ends with the interlocking portions 11 and 12, while spacing lugs 9 are provided near the outer end of said sections and bars. This construction forms a complete grate which is supported in the proper position in the re place by means of the hooks 2, while the inner edge of the grate proper will rest against or contiguous to the masonry of the fireplace.

l am aware that prior to n y invention tire grates of iron ttor the purpose of hanging` in the frame work of the fire place have been made. l therefore do not claim such a combination broadly, but

l claim:

1. The grate herein shown and described, consisting of the` front having ears to engage the frame of the lire place and hooks at its lower edge, and a grate composed of a series of sections having retainers at its front end to engage the hooks on the front and havingY interlockingportions at their inner ends to connect the grate and form a unitary structure.

2. lin a grate the combination with a vertically disposed front portion having grate supporting means7 of a grate composed of a series of sections each having at its outer end a hook; and lateral lugs for retaining` the sect-ions in the front and having their inner ends each formed on one side with a lateral wedge and on its other side with a lateral lug having a slot, said lateral lugs and slots acting to retain the grate sections in proper position to form the grates.

3. The fire grate herein sliownnnd dei scribed, Consisting' of the vertically disposed front portion, having a pair of supporting lugs on its inner face nea-r the top at each end, a pair of gra-te supportingliooks at its lower Corners on its innery face and ay series of recesses at its lower edge, a grate composed of intermediate and end sections hsving'interloeking lugs at their outer ends to fit and look in the recesses of ,the front, 10

In testimony lwhereof I liereunto affix my 15 signature.
