My invention relates to certain improvements in locomotive ash pans. These ash pans are secured to the underside of the fire box of the locomotive so as to receive ashes discharged from the grates. The fire boxes of locomotives are at the present t-1me very wide and the usual practice is to provide a central fire box having wide flanges which extend under the entire grate so that the ashes falling from the outer portions of the grates will be directed to the central ash pan. These side flanges are of necess ty made wlth very little incline so that the ashes accumulate on these side flanges instead of flowing by gravity into the central collecting portion of the ash pan, and means has been provided for pushing the ashes fronr the inclined flanges to the central collecting por tion of the ash pan, but even then the men have to, use pushers to dislodge the ashes.

One object of my invention is to so design the ash pan, which is attached to the fire box, that the ashes passing through the grate at the side of the fire box will drop onto comparatively steep outwardly inclined surfaces or onto ash hoppers carried by the truck, which is located under the fire box.

Another object of the invention is to provide means for hanging the ash pan by links to the frame structure.

A further object of the invention is to support the intermediate members of the grate structure by the upper section of the ash pan.

The truck having the ash hoppers mounted thereon is fully set forth 'andclaimed in application filed by me on the 27th day of November, 1931, Serial No. 577,622.

In the accompanying drawings:

Fig. 1 is a plan view of my improved ash pan for locomotives;

Fig. 2 is a side view, the mud ring to which the uppersection of the ash pan is secured being shown by dotted lines;

Fig. 3 is a transverse sectional view on the line 33, Fig. 2, showing the truck in dotted lines;

Fig. 4 is a side view showing the mean for operating the gates of the several chutes 50 of the ash pan; and

Fig. 5 is a plan view of the lower section of the ash pan.

Referring to the drawings: 1 illustrates the mud ring of the fire box of the locomotive. 2-2 are the grate bars and 33 are the intermediate supporting members for the grate bars. 4 is the upper section of the ash pan, which is flanged at each side and at the ends as at 5, the flanges being secured to the mud ring of the fire box.

The upper portion of this section 4 of the, ash pan is inclined to conform to the incline of the lower portion of the fire box. This upper section has a longitudinal depending flange 6 at each edge as shown in Fig. 3, andthe body portion of the pan is inclined as at 7 from points x at each side of the center towards the center of the pan, in which there is a longitudinal opening 8 extending substantially the full length of the ash pan, and the inclined portions merge into longitudinal flange-s 99, forming the walls of the longitudinal opening 8. i

The ash pan is inclined outwards from the point as, as shown at 10, to form chutes for 7 the ashes that drop from the outer portions of the grates 2-2. This flange terminates short of the depending flange 6 at each side, leaving longitudinal openings 11 for the discharge of ashes from the inclined chutes 10 Q anddirectly from the outer ends of the side grates 2 into hoppers 12 mounted on a truck 13 shown by dotted lines in Fig. 3.

This particular truck is set forth and claimed in the application referred to above. 14 is the front wall of the upper section of s the ash pan. This wall is inclined as shown and 15 is the inclined rear wall of the ash pan. In this inclined wall 15 is a recess 16 p for stoker mechanism in the present instance.

The upper section 4 of the ash pan is supported by the mud'rings 1 and carries the intermediate supports of the grates 2. 17 is a link member having a cross bar 18 and at g each end of this link are arms 19 which are coupled to the grate supporting bars 3 by plns 20, and extend'into pockets 21 in the ash pan and are pivotally connected to the ash pan by pins 22 so that the upper portion of the ash pan properly supports the intermediate frames of the grate of the locomotive.

23 is the lower section of the ash pan, in which are three hoppers 24 in the present instance. This lower section 23 is comparatively narrow'and extends between the wheels of the truck and rear frame of the locomotive, and the side members 25 of this lower section 23 extend on the outside of the flanges 9 of the upper section. The lower section receives the ashes that are discharged through the central opening 8 in the upper section 4 of the ash pan. The three hoppers 24 are spaced apart as shown in Figs. 2 and 4, and the lower open ends of the hoppers are inclined at 26. The openin s in the bottom of the hopper are used y gates 27 which fit against the inc ined portions 26 of the hoppers. The hoppers are reinforced in the present instance by ribs 28, as this section of the hopper is preferably made as aeasting as well as theupper section 4; The lower section 23 of the hopper is hung by links 29 from the longitudinal members 30 of the rear frame of the locomotive. These members in the present instance are channel shaped in cross-section but they may be of any shape without departing from the essential features of the invention.

The links are connected to the lower section 23 by pins 31 and to the frames 30 of the locomotive b pins 32. This construction allows a limite amount of movement of the lower section, which is essential. In the present instance the lower section 23 is made in two parts. One part has two hoppers and the other a single hopper and each part has a vertical transverse flange 33, the two flanges being secured together by bolts 34, but it will be understood that in some instances the lower section of the hopper may be made as a single casting. The hoppers 24 of the lower section are spaced apart so as to allow for clearance of the axles 35 of the truck 13 of the locomotive and the walls of the hoppers are inclined as shown in Figs. 2 and 4, so as to allow the ashes to freely flow into the hoppers and when the doors are opened the ashes will be readily dischar ed therefrom. In the present instance file doors are opened and closed by means of a hand-lever 36, secured to a rock shaft 37 mounted in bearings 38 on the forward end of the section 4 of the ash pan. Each gate 27 is hung by links 39 to pivot pins 40 mounted bearings 41, on the lower section 23 of the hopper. Secured to the rock shaft 37 are two arms 37a, which are connected by links 42 to one arm of a lever 43 on each side of the lower section of the ash pan. The levers 43 are mounted on a pivot shaft 44 carried by bearin s 45 projecting from the forward end of t e lower section 23 of the ash pan. The lower arm of each lever 43 is. forked and each lever is pivotally connected to a floatinglever 46 by a pin 47. One arm of the floating lever 46 is connected by a rod 48 to the forward gate 27 of the ash pan,

while the other end of the lei'er 46 is connected by a long bar 49 to a floating lever 50, one arm of this lever being connected to the gate of the intermediate ash pan and the other arm of the lever 50 is connected by a rod 51 to the rear gate. This gate opening mechanism may be modified without departing from the essential features of the invention.

By the above description it will be seen that the ash pan is located directly under the grates of the fire box and that the upper section has inclined surfaces which direct portions of the ashes through a central opening 8 into the lower section 23 of the ash pan, where the ashes accumulate in the hoppers 24. The ashes which pass through the grates near the outer sides of the fire box fall on the outer inclined surfaces 10 of the upper section 4 of the ash pan and are discharged into the hoppers 12 mounted on the rear truck of the locomotive, while the ashes passing through the grates at the extreme sides of the fire box fall directly through the openings 11 into the hoppers 12.

The lower section 23 of the ash pan sup.- ports the central portion of the upper section which rests upon internal flanges 52 on the side members and is preferably secured to said side members by bolts, as shown in Fig. 3. In some instances the flanges may be dispensed with when bolts are used.

By the above construction all ashes discharged from the grates either pass directly into the hop'iers of the lower section or flow into the sai hoppers or ass into the hoppers mounted on the trucE, and the inclines are at such an angle that no ashes will remain on the inclined surfaces of the upper ash pan.
