U it TATES JAMES N. LONG, OF PHILADELPHIA, PENNSYLVANIA.

ROCKING AND REVERSING GRA'TE.

SPECIFICATION forming part of Letters Patent No. 688,105, dated December 3, 1901.

Application filed July 8, 1901. Serial No. 67,520. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JAMES N. LONG, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certainhereinafter set forth, reference being had to v the accompanying drawings, in which-- Figure 1 is a transverse section of a grate constructed in accordance with my invention; and Fig. 2 is a plan View of the same, partly in section.

1 represents the outer frame of the grate, which in the present instance is rectangular; but it may be of circularor other desired shape, depending upon the shape of the fire-pot in connection with which it is to be used. Within this outer frame are hung the grate-bars 2, of which as many may be used as desired, five being shown in the drawings, each of said grate-bars having at the ends trunnions 3, adapted to bearings in the frame 1, so that each bar is free to rock within the frame. The frame 1 also has trunnions 4-, by which it may be hung in the fixed frame of the stove or heater, so as to be tilted for dumping the contents of the fire=pot into the ash-pit, the front trunnion 4: being tubular for the passage of the front trunnion 3 of the central grate-bar 2, whereby power may be applied to said grate-bar to rock the same.

The central grate-bar and the two bars flanking the same have upon each side a toothed segment 5, and the outer bars of the series have such segments on their inner sides, the toothed segments of adjoining bars meshing with each other, so that power ap plied to the central bar to rock the same will be transmitted therefrom to the other bars of the series and will cause a like rocking movement of each of said bars. In the present instance the bars have these toothed segments at the longitudinal center of each bar; but the segments may bear any other desired relation to the bars, or each bar may have two or more of the segments disposed throughout its length, if the use of more than one segment on the side of each baris considered neeessary for the purpose. When this method of gearing together the bars of the grate is adopted, no burning out of the connections or other bad result will follow if in dump ing the grate the same is accidentally re versed and left in that position, since the building of the fire upon the gratein the reversed position will have no ill effect either upon the bars or their connections.

Having thus described my invention, I claim and desire to secure by Letters Patent-- A grate havinga frame with trunnions centrally disposed thereon whereby it is pivoted so as to be reversible, one of said trunnions being tubular, and a series of gratebars pivoted within said frame so as to be capable of rocking therein, said bars being geared together byintermeshing toothed segments formed upon the sides of the bars, and the pivot-trunnion of the center bar of the series passing through the tubular pivottrunnion of the outer frame, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES N. LONG.
