LOCOMOTIVE' ASH-PAN.

973,765. Specification of Application filed Ja tuarydz, 1909. Serial No. 471,9-18' I a citizen of the United States, residingatf Louisville, in the county of Jefferson and State of Kentucky, hardinvented a certain new and useful Improvement in Locomotive Ash-Bans, of which the following is a full. 'elear, 'nnd exact description. referenee being had to the accon'ipanying drawings. I

The object of this invention is to provide simple and eilieient means for cleaning the ashes (aft: of a hit-.oinotive ash-pan without.- requiring the attendant to go under the 1000- motive. In accon'iplishing this object I provide a system of conduits and valves to tnable water under pressure to be blown against the ashes, shoving them out of the pan. and 1 provide a min which is partienlarly adapted to allow the discharge of ashes so nioved. To this end a. vondnit is coma-wted with the boiler and is arranged to discharge water with great. 'foreeagainst the ashes at various points, so that the whole mass is quickly shoved along the pan. l lo eate the dist-barge members of the conduitat. an intelmiediate position inthe pan and at" the ends of the pan I provide doors \Yltltll normally close the pan. these doors when released serving-as battles topropertv deflect the discharging ashes.

The invention, includes broadly the combination of an ash-pan provided with my forcing and" discharging mechanism. or either of them, as above referred t'of L Other features hereinafter explained are also included in .my invention, wherefore the invention is best.- sinu'marized as consisting of the combination (if-cooperating ele-: ments hereinafter explained and set out in the claims.

To hold the doors normally in closed position while allowing their convenient. re.- lcase. l provide the following mechanism. livoted to the under side ot'gthe ash-pan is a lever Q which is connected on one side of its pivot with one door by a chain it and on the other side of its pivot. with the other door by a chain ll. these chains being connected to the cars /l on the under sides oli the doors. This lever extends beyond the ash-pan and is there connected by a link I with-a chain .1" which wraps aroun'd a windingdrum h. This drum is provided with a hand wheel S by which it may be turned and with a ratchet and )awl S for holding it: 3y this means the t oors may be drawn up snugly against. the ends of the ash-pan. as shown in full lines in Figs. l and 10. while. by releasing the pawl S the weight of the doors will cause them to swing downwardly away from the ends of the pan bottom.

The conduit by which water under pressure is blown into the intermediate portion of the ash-pan to force the ashes along the bottom and out. thrtmghthe door openings, is shown in two forms. according to whether the ash-pan is continuous or divided. 1 will describe lirst the former emlmdiment'.

Referrine to Figs. l lo 3 and ti to 9. there will be seen a discharging member for the water conduit. which is designated T.. This n'ielnber is located at an iiitern-iediate position on the bottom ot-the ash-pan. as shown. It extends trznisversely of the ash-pan and out t-llrough'the side wall D thereof, It has intermediately a. )art'itiont extending from end to end and t ividing it into two passage ways, I and I. llach passagew'ay has a series of discharge openings f". I through the side walls of the conduit ltl\\'il,l'tl the respective ends of the ash-pan. From the top of this discharge member rises a web I which serves-as a separator. causing the ashes -falling-from the grate to pass on to one side or the other of the member. This discharge member may be secured to the ash-pan-.bottom by lugs} projeeting from the op )osite sides of the member. The del discharge member is neferably a casting. The end thereol which extends out through the ash-pan wall .I) is preferably made bemisplierical. as shown at. I. whereby 'it may 1nal 'ea close connection with that. wall by lit-ting a round hole in the wall and without requiring .an accurate placing of the casting. The ehalnlwr of the casting is bentumvardly toward the entrance end, as shown in Figs. 3 and 7, so that the rounded head may be above the angle iron (i. The piping for the water leads in two branches from a suitable point to the head t on op )0- site sides ()Iftl partiti n it. '.\s shown. t iis wiping star frtm the win er leg of the boiler suitable val U connects this pipe see- .by the end bar X.

tion with a downwardly extending section U". This section leads to a suitable threeway valve 'lirom lhcopposite sides oll which extend the. discharge pipe which are shown as passing longitudinally and then downwardly and then turned inwardly to connect with the two sides of the head t".

From the above described constructitm it will be seen that the three-way valve Y may connect either side of the discharge casting with the. pipe U and that; then when the valve U is opened water under pressure is admitted t lireetly from the boiler to the casting and discharges in large quantity toward the corresponding end of the ash'pan. passing horizontally a short distance above the bottom. By making the. openings t of such size that their aggregate area is substantially equal to the area of a eross section of the passageway through the pipe, I am enabled to obtain a great pressure, equally distributed. The correspomling door being open before this pressure is turned on, the result is that. the \VhOlC-IIH'ISS of ashes is shoved by the pressure lengtlnvise of the pan and out through the open doorway.

,This mass of ashes passes against the depending door. which acts as a battle and insures the proper discharge downwardly. the.

doors swinging outwardly during such discharge toward an extreme position limited ll. is important for the best. results to have the described relation between the aggregate areas of the openings t and the 'area of cross section of the passagewa v, for if the areas of the openings were materially less than that of the passageway,' t-liepressure would be reduced so as to be inellieient, while it? the combined area were greater there would be annnequal dist rib'ution, the openings t nearest the entrance pipes receiving an undue portion of the passing liquid. -To properly guide the water and prevent its spin-ting upwardly against the grate. I pro videsmall Shields 13 formed on the side walls of the casting aml projecting'over the. clotresponding-openings I".

The construction of discharge members as shopn in Figs-.10 and it is modified.'b ut the saine ip principle. Here the ash-pan is shown as divided, the llool 1f extending upwardly intermediately. as shown at I by reason of the axle standing beneath the tire. box. \Vith such an ash-panI provide two discharge castings, in place. of the one double casting T heretoforedescribed. These castings X are secured on the-bottom of the ash-pan adjacent to the upwardly extending intermediate wall F thereof. Each casting X is shown as held in place by suitable lugs .0. They each have discharge openings :0 surmounted by sl1ield s Sim-i lar to that already described. Each casting has a head passing out through the sidewall too of the ash pan, the head as as shown being made rectangular. Each head is connected I); branch pipes V with the three-way valve which, as heretofore described, may receive water under pressure under the control of the valve U.

It will be seen that in both forms of my invention I have provided at an intermediate ortion of the ash-pan oppositely facing disc large conduits. These conduits are under the control of a three-way valve and a. common valve piped to the boiler, which arrangement allows the water to be forced under pressure through either conduit toward the corresponding end of the pan as desired, the discharge from the end of the pan being controlled by the depending end door. This end door, it should be noted, not only makes a close. connection with the sides and bottom when the door is closed, to return the ashes, but when opened still preserves the inclosure complete except toward the track, so that the ashes and cinders will be invariably diverted to the track or pit and not allowed to blow over the machinery. The overlapping flanges and cleats make the connection tight without requiring actual engagement-or such snugness as would result in trouble from expansion and contraction of the ash pan. These coiiperating flanges and edges constitute a trap which is very effective in nreventiug leakage. Furthermore. I have braced the sides of the ash pan adjacent to the doors so that they will not be warped by heat, to either bind the door or cause lea age.

It will be understood that, while I have shown these two embodiments of my invention, the invention may be readily applied in other ways. Indeed, many changes and modifications may be made in it and I do not intend to limit myself to the particular form 'showIn further than the prior art requires.

Having thus I claim is:

1. The combination, with a. locomotive ash pan having an exit, of means for directing a fluid discharge therein to propel the ashes described my invention, what through the exit, and means including a door and guiding walls for closing said exit and for controlling the discharge of ashes therethrough and l directing them downwardl while reventing their lateral sprea ing, whereiiy an effective downward discharge isinsured.

2. The combination of a locomotive ash pan, means for directing a fluid discharge therein, and a. controller for efiecting the downward discharge of ashes and preventing their lateral spreading, said controller. ineluding a door which serves in one position to close the exit from the ash pan and in an other position to form a portion of the downward guide for the discharge of ashes.

3. The combination, with a locomotive ash pan, of means for directing a fluid discharge therein, and a pivoted door which in one position coiiperates with the sides and bottom of the pan to close the exit from the pan and in another position leaves'an open space between the door and bottom of the pan while maintaining closed the space be-- tween the door and side walls of the pan.

4. The combination, with a locomotiveash pan, of means for directing a fluid discharge therein, and a pivoted door operating between extensions of the ash pan sides and serving to close the exit'from the pan and to form a portion of a downwardly extending chute when in open position.

5. The combination, with a locomotive ash pan, of means for directing a fluid discharge therein, extensions of the side walls of the pan, a door operating between said elevensions to close the pan or form a portion of a downward chute. the ends of the door being free from-the side extensions, and ribs carried by said extensions and overhanging the door to make a. tight closure therewith.

6. In an ash pan, the combination of side walls, a swinging end door between the side walls mounted on a rod supported by the side walls, and cleats carried by the side walls with which said door may connect when closed, the door having flanges to "overlap the cleats, and the door havin also a bottom flange which the bottom 0 the ash pan is adapted to overlap when the door is closed.

7. The combination, with an ash pan pro-- vided with oppositely arran ed openings, of means for discharging liquid into it to propel the ashes through said openings, and means including a manifold within t e pan, said manifold carrying an upwardly. extending web adapted to form a division for the ashes, the manifold discharging both sides of the web;

In testimony wher eof,-I hereunto affix my signature in the presence of two witnesses.
