FIRE-GRATE.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed February 27,1905. Serial No. 247.450.

To all whom it may concern:

Be it known that I, HORACE Bum), a citi- Zen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Fire-Grates, of which the following is a specification.

My invention relates to that class of firegrates wherein a number of separate bars are assembled together on a suitable support to form the grate, my object being to provide in a fire-grate a simple and efiicient construction and arrangement of parts whereby the bars of the grate may be supported in vertical position and in spaced relation to each other without interfering with the air-space between adjacent bars, whereby any one bar of the grate may be substituted for another and whereby the bars may be rearranged to any extent desired to substitute portions of the grate that have not been affected by the heat of the fire for those portions of the grate that have. .v

Having this object in view, theinvention consists in the novel construction and arrangement of parts, which will be hereinafter fully described and claimed.

In the drawings, Figure 1 is a plan view of my improved grate, a number of duplicate parts being omitted. Fig. 2 is a sectional elevation of the arts shown in Fig. 1. Fig. 3 is a sectional p an as on the line 3 3 of Fig. 2. Fig. 4 is a transverse section as on the line 4 4 of Fig. 2. Fig. 5 is a plan view of one of the front end members.

My improved fire-grate comprises the front and back end members 1 and 2, res ectively, and the grate-bars 5, arranged si e by side and end to end and extending between the end members 1 and 2, as shown in Fig. 1.

Any number of the end members 1 and 2 and bars 5 may be employed, depending upon the size of the grate desired.

The end members 1 and 2 rest upon suitable supports 6 and 7, respectively, and the grate-bars 5 rest upon the end members 1 and 2 and suitable bars S, extending at right angles to the grate-bars 5.

The end members 1 each comprise a body portion 9, arranged transversely of the gratears 5, and in the present instance being of a length about equal to the width of two bars 5. Each member 1 is provided with two pairs of inwardly-extending projections l() and 11, affording between each pair a verof each opening 12 or the projection 10 is provided with a vertically-arranged groove 13. The projections 1() and 11 are arranged below the upper surface of the body portion 9 for purposes hereinafter explained.

The end members 2 are substantially the same in construction as the members 1, excepting that they are oppositely disposed that is, their projections 10 and 11 extend toward the projections of the members 1 and their rearward sides are provided with projecting teeth 14. I have therefore designated the parts of the end members 2 by the same reference characters as used in describing the end members 1, believing that the description of one will sufiice for the other.

The grate-bars 5 are alike in every particular and each bar comprises a longitudinal vertical web 15, provided on its upper edge with laterally-projecting teeth 16, lthe distance between each end of each bar and the teeth next adjacent thereto being such as to provide between the adjacent end teeth of two bars, when assembled end to end, a space substantially equal to the spacebetween two adjacent teeth of either bar, so as to form, in effect, one continuous bar, as shown in Fig. 1, and each end of each bar 5 or web 15 is beveled in a substantially vertical plane to provide a union line between two bars when assembled end to end, which will be oblique to the longitudinal center of the bars. This latter feature prevents the hoe or other firetool entering the space between the ends of the bars in cleaning the fire.

The grate-bars 5 are arranged in two sets, front and back, and they extend to meet each other midway of the grate. The forward ends of the webs 15 of the front bars are arranged within the spaces 12 between the projections 10 and 11 of the end members 1, and the rearward ends of the webs 15 of the back bars are arranged within the spaces 12 between the projections 10 and 11 of the end members 2, thereby maintaining the bars 5 in vertical position and in spaced relation to each other. Each end of the web 15 of each bar 5 is provided with a vertical rib 17, which is arranged within its adjacent groove 13 to prevent endwise movement of the web 15 from between the projections 10 and 11 during the expansion and contraction of the grate under the influence of heat.

The end teeth of the bars 5 rest upon the projections 10 and 11, and the vertical ditically-arranged opening 12. One side wall l mensions ofthe teeth are about equal to the iro distance between the top of the members l and 2 and the top of the projections 10 and l1, to the end that the upper surface of the bars 5 will lie flush with the upper surface of the members l and 2.

By the construction hereinbefore described it will be seen that the front grate-bars may be readily substituted for the back ones without disturbing. the position of the end members l and 2, and, in fact, any one of the bars 5 may be substituted for another and maintained in vertical position and in spaced relation to adjacent bars, and at the same time uninterrupted air-spaces between the bars is provided. It willv also be seen the bars 5 may be rearranged to any extent desired to substitute portions of the grate that have not been affected by the heat of thev iire for those portions of the grate that have..

l. In a ire-grate, an end member having a plurality ofv verticallyarranged openings therein, one side wall of each opening being provided with a vertical groove, and a plu rality of grate-bars each being provided withl Va vertical rib and having one of its ends arranged. withinone of said openings and its rib arranged within the adjacent groove,

whereby said bars are maintained in vertical positions and in spaced relation to each other and whereby endwise motion of the bars from within said openings is prevented.

r 2. In a nre-grate, an end. member provided with projections aifording a plurality of ver.- tically-arranged openings, one side wall of each opening being provided with a'vertical groove, and a .plurality of grate-bars each being provided with a vertical rib and having -one Aof its` ends arranged within one of said openings and its rib arranged Within the adjacent groove, whereby said bars are maintained in vertical position and in spaced relation to each other and whereby endwise motion of the bars from within said space is prevented.

3. In a nre-grate, an end member provided with projections below the upper .surface .thereof aifordinga plurality of vertically-arranged openings, and a plurality of gratebars each having its upper surface substantially lush with the upper surface of said end member and having one of its ends entering one of saidfopenings and being provided with laterally-projecting portions resting upon said projections, whereby said bars are maintained in vertical position and in spaced relation to each other.

4. In a nre-grate, an end member, provided with projections below the upper surface thereof affording a plurality of vertically-arranged openings, one side wall of each opening being provided with a vertical groove, a plurality of grate-bars each having its upper surface substantially flush with the upper surface of said end member and having one of its ends entering one of said openings and Abeing provided with a laterally-projecting portion resting u on said projections, and a rib on each bar fitted to one of said vertical grooves, whereby said bars are maintained in vertical position and in spaced relation to each other and whereby endwise lmotion of the bars from Within said spaces is prevented.

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