In the present form we provide the under side of the end bar of the grate as 5 the grate with a cam-shaped projection upon shown, and in Fig. 1 we have shown this end 9 5 its under face upon which travels a roller carbar as provided with a cam-shaped lug e ried by the inner end of the foot pedal to force against which the said inner end of the lever the grate against its preponderance of weight, works, and this inner end preferably carries the grate automatically returning to its nora small roller E which may be grooved and is 1. mal position and the roller traveling in the loosely journaled on the end of the lever. mo

Or, instead of this construction and arrangement of parts we may connect the inner end of the lever with the grate bar by a pivotally connected link F as shown by dotted lines in Fig. l. I

In order to limit the movement or the foot lever so that it may be used for shakingthe grate instead of dumping and also to prevent dumping when shaking we provide a pivoted arm G the outer end of which may be provided with a suitable knob or handle 9, the said arm being pivoted on a vertical pivot g on the frame and its inner end carries a depending lug G. When the arm is moved horizontally on its pivot so as to throw this lug in the path of the foot lever it permits the lever to move but slightly as will be readily understood from Fig. 2, but when it-is moved in the opposite direction the foot leveris free to move its entire limit to throw the grate into the position in which it is shown by dotted lines in Fig. 1. lhe curvature of the lever permits of this movementwithout touching the arm or its ing. A stop pin h maybe provided to limit the movement of the arm G; This arm may be moved by the foot. The advantages of such a construction and arrangement of partsas above described will be at once apparent. The foot pedal is op= erated by the foot as illustrated in Fig. 1, in" I a vertical direction, not horizontally, there is no necessity of stooping down to-grasp it by the hand the same lever and the'same downward pressureserve to both shake and dump the grate. The grate automaticallyreturns to its horizontalposition when pressure isreing the same, and an interposed arm pivoted so as to bring its inner end over the foot pedal to limit its movement for shaking the grate and out of the path of the foot pedal for dumping the grate, substantially as specified.

2. The combination with a dumping grate,

of a pivoted foot pedal having a bend, a roller at the innerend thereof, and a movable arm with a lug to engage the pedal at said bend, as and for the'pnrposespecified. 3. The combination with a pivoted grate having cam-shaped lug on its under face, of a pivoted foot pedal carrying a roller to engage said lug and apivoted arm havinga lug to engage said pedal, as set forth.

4. The combination'with a dumping grate, of' a' substantially horizontal foot pedal having its inner end disconnected from and mounted to act upon the grate, and a horizontal arm pivoted on a higher plane and having'depending lug to engage the pedal to-hold the same"against'movementyas set forth.

In testimony whereof We aflix our signatures in presence of two witnesses.
