LOCOIVIOTIVE ASH-PAN.

SPECIFICATION' forming pari: of Letters Patent No. 299;955,.dated June 10, 1884.

i Application filed December 24, 1888. (No model.)

States No. 240,430, granted .I une 7, 1881; and

it consists in suspending the ash-pan from lugs or supports cast upon the frame by means of ears or lugs cast upon the ash-pan, so as to leave the space between the bottom of the ashpan and the bottom of the ash-pit entirely free for the circulation of air.

It also consists in opening and closing the door of the ash-pan and locking the same closed by means of a crank-shaft extending out through the side of the ash-pit, and provided with a curved arm for supporting the door, and a spring-catch engaging the crankarm.

In the accompanying drawings,which form a part of this specification, and in which similar letters of reference indicate like parts, Figure l is a sectional elevation of a device embodying my invention. Fig. 2 is a plan view, looking down from line 2 2 of Fig. l. Fig. 3 is a transverse section on line 3 '3 of Fig. 2. Fig. 4 isa detail side elevation of the ashpan, and Fig. 5 is a side view showing the device for opening and closing the door and locking the saine.

In said drawings, A is the water-leg of the locomotive-boiler, surrounding the fire-box A.

B B represent the grates; B', the shaker-rod, G, the curved deilecting-plates. l

C is the ash-pit, provided with hinged damper c; andDis the ash-pan inside the ashpit, and provided with flaring sides and ends,

` which project up under the curved detleetingplates. rIhe ash-pan D is provided with notches or offsets d d at its corners, so that its ends may project between the corners E and E of the frame F. The ash-pan is also provided on its sides, near each corner, with projecting ears or lugs di d3, from which it is suspended or supported by means of the projecting lugs d* d5, cast on the frame. The projecting lugs d* are provided with projections d, and are made long enough, as are also the notches d in the end of the ash-pan, so that when the end of the ashpan is raised to permit the ears d2 to slip over the offset df' the ash-pan may be slipped back sufliciently to allow the ears d of the front end of the ash-pan to slip oft their supporting-lugs d5 and'drop down, when the ash-pan may be removed bodily from the ash-pit. The ash-pan D, at its front end, is provided with a hinged door, K. One side of this door is hinged to the ash-pan by means of a screw-bolt or pivot, 7c, and its other side is hinged thereto by means of a crank-shaft, G, which projects out through the side of the ashpit, and is journaled in a sleeve or bearing, g, secured to the side of the ash-pit by means of screws or bolts g', which pass through a flange, g2, cast upon said sleeve g. rlhis crank-shaft G is provided with a curved or bent arm, H, which serves to close the door, and hold the same closed.

L is the crank-arm by which the crank-shaft is turned in opening or closing the door, and L is a spring catch or locking device secured to the frame, which engages with the crankarm, and serves to lock the same when turned, so as to close the door.

It will be observed that the door K stands Haring, the same as the sides and end -of the ash-pan, so that the door will open or fall down of its own weight whenever the crankarm is released from the spring-catch L.

By operating the door from a crank-shaft at the side, having a bent arm, and by suspending the ash-pan in this way by means of ears resting upon lugs or projections upon the frame, instead of resting the same upon standards or supports from beneath, as shown in my patent above referred to, the space between the bottom of the ash-pan and the bottom of the ash-pit is left free and clear, so as to offer no obstructions to the circulation of the air, to the cleaning out of the ash-pit, or to the removal of the ash-pan, when occasion may require. i

The crank-shaft is provided with aset-screw, n, passing through a collar, a', by loosening whichthe crank-shaft may be slipped out when it is desired to remove the ash-pan.

I claiml. The combination, in a locomotive-boiler, of the grates with the downwardly-curved de- IOO iieetingfplates7 the ash-pit, and the ash-pan inside the same, having` ilaring sides7 and suspended from the frame under said defiectingplates, the space between the bottom of the ash-pan and the bottom of the ashfpit being free and clear, so as to offer no obstructionv to the Vcirculation of the air or to the clearing out of the ash-pit, substantially as specified.

2. The combination of the gratos with the downewardlydeiiecting plates, ash-pit, ashpan inside the same, provided with offsets d d at its corners7 and ears d2 d and support ing-1ugs d* d5, projecting from the frame, said lugs d* being provided with offsets d6, and being made long enough to permit the ash-pan to slide back on said offsets sufficiently to a1- low the front end of said ash-pan to drop oft' its supporting-lugs in order to remove the same, substantially as specified.

3. The combination of the grates with the deiieeting-plates, the ash-pan having Haring sides and suspended beneath the same from the frame, and a crank-shaft projecting out through the side of the ash-pit, and having a bent or curved arm for opening and closing the door of the ash-pan7 substantially as specified.

4f. The combination of the ash-pan and its door with a crank-shaft providedwith a bent or curved arm for opening and closing the door; and a spring-catch adapted to engage with the erank-arn1 for locking or holding the door closed, substantially as specified.
