JOHN PLAYER, OF CHICAGO, ILLINOIS, ASSIGNOR TO AMERICAN LOCOMO- TIVE COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.

LOCOll/lOTll/E ASHmPAN.

SPECIFICATION forming part of Letters Patent No. 696,48 5, dated April 1, 1902. i Application led November 7, 1901. Serial No. 81,477. (No model.)

To all whom. t may concern:

Be it known that I, JOHN PLAYER, of Chicago, in the county of Cook and State of Illinois, have invented-a certain new and useful Improvement in Locomotive Ash-Pans, of which improvement the following is a specification. i

My invention, while more particularly designed for application in connection with locomotive-boilers of the wide or widened rebox type, is likewise and equally applicable to those having narrow lire-boxes 5 and its object is to provide means whereby the contents of the ash-pans of fire-boxes having a co1nparatively large grate area may be readily and expeditiously discharged from time to time as desired and the dischargeopening be maintained tightly and securely closed during the periods intervening between the discharge operations.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure lis a side view in elevation of a locomotive ashpan, illustrating an application of inyinvention with the discharge-doors closed, as in the running condition of the engine; Fig. 2, a similar view with the discharge-doors opened to dump or discharge the contents of the ashpan; Fig. 3, an inverted orbottom plan View; and FigA, a partial transverse section through the rire-box, showing the ash-pan in end elevation. i

My invention is herein illustrated as applied in connection with a wide nre-box 5, which is located above a pair of trailing wheels 3. The upper section or body 23 of the ashpan, which is formed of sheet or plate metal and connected to the fire-box in the usual manner, is inwardly and downwardly tapered, so as to clear the wheels 3 and frame 8 of the engine and to direct the residuum which drops into it from the superposed grate toward its middle portion. The lower section of the ashpan, which is preferably made of cast metal, is in the form of one or more hoppers or discharge-chutes 24, two being shown in this instance, each of which is open at top to the upper section and has an inclined bottom in 5o which there is formed a discharge-opening,

preferably extending throughout the full distance between the side and the end walls of the hopper and closed by a discharge-door 25, which is fitted to abut against and make a tightjoint with the walls of the hopper around the discharge-opening. Each of the dischargedoors is suspended upon the sides of its hopper in such manner as to be automatically closed and maintained in contact with the bottom thereof1 by gravity. To this end the discharge-door is pivoted at its sides to the lower ends of a pair of hangers or suspensionlinks 26, the upper ends of which are in turn pivoted to the side walls of the hopper, the pivots of the doors being located in such position thereon that when the door is closed the suspension-links will stand in an inclined plane which intersects the door above the intersection therewith of the vertical axial plane of the pivots by which the suspension-links are coupled to the hopper. Under such construction it will be seen that, except when restrained by the application of an excess of force acting in the opposite direction., the door will be swunginto and held in closed position by the action of gravity upon it and its suspension links, and in holding the door closed such action will be exerted irrespective of the downward pressure which may be eX- erted on the door by the weight of the material which may be contained in the body of the ash-pan and the hopper.

The discharge-doors 25 are opened to effect the discharge of material from the hoppers when desired by means of a transverse operating-shaft 27, having a hand-lever 28, by which it may be rocked in its bearings, fixed upon one of its ends and projecting outwardly in position to be conveniently accessible to the reman. Oppositely-projecting arms 29 are iiXed upon the shaft 27, substantially in the longitudinal central plane of the ash-pan, and are coupled by links 30 to .lugs 3l on the discharge-doors. By movement of the lever 28 into the position shown in Fig. 2 the doors 25 will be opened, and upon the release of the lever they will be closed by gravity and remain in their normal positions-z`. e., in bearing against the bottoms of the hoppersuntil the hand-lever is again manipulated.

In discharging'thecontents of the hoppers when two or more of them are employed, as

ICO

is ordinarily the case, it is desirable that the doors should be simultaneously opened and that their opening and closing movements should be equalized to prevent jamming and permit them to freely adjust themselves under all conditions to their bearing-surfaces on the bottoms of the hoppers. To this end a floating or sliding connection of the doors is preferably provided, a connection of such character being effected in the instance shown by journaling one end of the operating-shaft 27 in a rigid bearing, which is formed in a horizontal bar 32, fixed to one side of the hoppers, while the opposite end of said shaft is journaled in a` floating bearing formed in the lower end of a link 33, the upper end of which is journaled on a pin xed to the side of the hoppers opposite that to which the bar 32 is connected. Underthis construction the sticking of one of the doors in opening will not cause it to act as a fulcrum for the other, as the degree of iloating movement admitted in the arms ofthe operating-shafts to which the doors are coupled will cause them to be moved simultaneously and allow them to correctly adjust themselves to their seats on the bottoms of the hoppers.

My invention has been found in practice to enable the contents of large ash-pans to be readily and expeditiously discharged, and the mechanism employed, which is of ready application in locomotives of the various types now approved in service, insures the effective closure of the discharge-openings of the ashpan while the engine is running, therebypreventing liability to the dropping of hot cinders upon the right of way. The doors, being exempt from risk or being choked or jammed by accumulations of cinders or snow or ice, may be easily opened whenever desired.

I claim as my invention and desire to secure by Letters Patent- 1. In a locomotive ash-pan, the combinationof an upper section or body, a lower hopper or discharge-chute communicating therewith and having an inclined bottom provided with a discharge-opening, and a dischargedoor suspended in position to be normally seated on the hopper-bottom by the action of gravity.

2. In a locomotive ash-pan, the combination of an upper section or body, a lower hopper or discharge-chute communicating therewith and having an inclined bottom provided with a discharge -opening, a dischargedoor suspended in position to be normally seated on the hopper-bottom by the action of gravity, and means for unseating the discharge.- door by the application of an oppositely-acting force.

8. In a locomotive ash-pan, the combination of an upper section or body, a lower hopper or discharge-chute communicating therewith and having an inclined bottom provided with a discharge-opening, a discharge-door adapted to seat on the hopper-bottom and close the discharge opening thereof, and
