LOCOMOTIVE ASH-PAN.

Specification of Letters iatent.

' To all whom it may concern:

' hopper will be carried by wheels running- Be it: known that 1, WILLIAM CHENEY, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Locomotive Ash-Pans, of whichthe following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in locomotive ash pans, the object ofmy inv ention being to construct an improved ash pan for locomotives which will eliminate the annoyances and dangers incident to warping caused by the heat of cinders and ashes carried thereby, and which ash pan is provided with suitable track for the support of a wheeled bottom, and track which bottom is so isolated with relation to the ash pan that hot cinders or ashes carried by the pan are prevented from warping said track and falling from'the ash pan.

A further object of my invention is to provide an improved locomotive ash pan with cooling webs at its sides for supporting wheel-tracks, whereby the bottom of the upon said tracks, and the tracks themselves will be kept cool and prevented from warping.

For the above purposes my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter made clear, pointed out in the claim and illustrated by the accompanylng drawings, in which:

Figure 1 is an elevation illustrating a portion of a locomotive fire box, the ash pans carried by the tire box and my improved attachments carried by the ash pans together with the means for operating the s lding bottoms for the ash pans; Fig. 2 is a plan partly in section taken on the line 22 of Fig. 1; Fig. 3 is an enlarged rear end elevation illustrating a portion of the tire box, one of the ash pans and my improved hopper and parts carried thereby; Fig. 4c is an enlarged, sectional. elevation taken on the line H of-Fi 1; and Fig. 5 is a longitudinal, sections elevation taken on the'line 5-5 of Fig. 4, the sliding bottom and parts carried thereby being shown in dotted lines in arr-open position. I p

Referring by numerals to the accompany ing drawings: 1 designates thev locomotive lire box and 2 the ash pans carried by the struction, being made up of sheet metal, that IS they are constructed of the same general conformation as the ordinary ash pan and are somewhat shorter from top to bottom than the ordinary ash pans.

Carried by the ash pans and preferably secured thereto by bolts or rivets 3 are the cast iron hoppers 4t and 5, each being. a counterpart of the other, the hopper 4 being secured to the forward ash pan and the hopper 5 being secured to the rearmost ash pan. The end walls 6 of the hoppers converge from top to bottom while the side walls 7 of the hoppers are substantially vertical. Projecting laterally from the outside facesoi' the walls 7 and of a length approximating the length of the hoppers are the webs 8. The hopper complete together with'said webs 8 are preferably cast inone piece. Secured to the side faces of the webs 8 are the tracks 9 which are of a length greater than the webs and project laterally beyond said webs. The upper faces of the tracks are in a plane above the upper faces of the webs 8 for purposes hereinafter made clear.

10 andv l1. designate, the sliding bottoms for the hoppers l and-5 respectively, each of which bottoms is provided with hangers 19, there being two hangers on each side of each bottom. The hangers, as shown in Fig. 4 of the drawing, are preferably constructed of a single piece of material and comprise a portion arranged to be secured to the bottom face of the bottom which extends outwardly some considerable distance from the side of the bottom. From thence the piece is bent upwardly approximately at right angles to the portion which is secured to the liiwer' side 01. the bottom. The upright por- Fat-tented June 13, 1911;

hopper as shown in Fig. 5, thereby forming a ledge 16 at the forward endof each bottom to 'eatch and hold ashes or cinders whiih 't the end of the bottom opposite the ledge 16 are the right-angled extensions 17 of the walls 15 and as shown in Fig. 3 the exten- -sions 17 are reduced at 18 and the reduced portion 18 is provided with an inclined face 19 designed to hold and receive cinders and ashes that maybe discharged rearwardly from the ash pan. 'j The extensions 17 form a stop to lim t the forward movement of the bottoms, the rearwartillfiovement of the bottoms being limited by engagement of the hangers 12 with the outer en s'of the cross rod 20 carried by the rear ends of the tracks 9. The bottom 11 at vious that the ordinary hopper and ash pan its rearmost end is provided with a perforated car 21' which projects downwardly from the bottom faceof the bottom and is arranged at the approximate transverse center of the bottom. Pivotally connected with the car 21 is a link 22.and connected with the link is a lever 23, the upper end of which lever projects through the deck of the cab where it may be within easy reach of the operator. Atthe forward end of the bottom 11 and projecting downwardly from the rear face thereof and located adjacent the sides 15 are the perforated ears 24. The

forward bottom 10 is provided with perfo-- rated ears 25 arranged adjacent the sides of been constructed of heavier material than, the ash pans. These hoppers are usually formed hollow for the purpose of introduc ing steam for thawing or preventing freez ing of the contents of the ash pans and hoppers, but I believe the cast metallic ash pan,

as shown, with such a longitudinal web is new. i It is to be understood that such hoppers must withstand great heat and consequently rapid variations of heat as for instance when the hot ashes or cinders are emptied and rapidly cooled, thus it is obissubject to warping. The construction of the hopper, as shown with the reinforcing web 8, is practically non-warpable and due tov the novel construction of sliding bottom for the'hoppcr, the dropping of live coals or cinders when the locomotive is in motion is eliminated. v

In practical operation, assuming the parts to be assembled as shown, it is obvious that ashes and cinders discharged from the grates within'the fire box will fall, by gravity, into the pans and be held and carried in the hoppers. To persons familiar with the art, it

, is obvious that such ashes and cinders must not be discharged promiscnously upon the road-bed for the reason that the cro'ssties or bridge timbers of such road-bed would be burned and, perhaps, entirely destroyed v by fire-from such live coals or cinders. 'It is to be noted that the-sliding bottoms project some slight distancein advance of the bottom portions of the hopper, thus making a ledge upon it to carry live coals or ashes discharged from the hopper, and it is to be noted that at the opposite ends of the bottoms there is an inclined face for carrying live coals or ashes that might be discharged from the hoppers. In order that the sli'dlng bottoms may freely movev into either o'pen' or closed positions relative to the hoppers,,it is essential that the hoppers and en aging parts of the bottoms be so construe as to not be easily warped out of shape. Such warping is eliminated by forming the walls of the hopper of considerable thickness and reinforcing such walls by the webs. The Webs 8 not only serve to reinforce the side serve as a support for the tracks upon which the bottoms are moved. When it is desired walls of the hopper to prevent warping but to empty the hoppers and pans, it being understood, to persons familiar with railroading, that such discharges are made at points where ash pits are located for this purpose,

one of the operators of the locomotive,v

either'thefireman or the engineer, will grasp the lever 23 within the cab of the locomotive I and by manipulation of the lever draw the bottoms 10 and 11 rearwardly. The movement of the bottoms is limited in a rearward direction by the engagement of the rearmost hangers 12 with the projecting ends of the cross rod 20 connecting the tracks at their rear ends. Thus, it is obvious that the hopper iswholly open and that the contents thereof will be rapidly discharged. To close the hoppers the motion of the lever-23 is reversed and the bottoms 10 and 11 are moved forwardly until the portions 17 of the walls of the bottom engage with the rear faces of the lower ends of the hoppers. I claim: I v
