LOCOMOTIVE ASH-PAN.

Application filed March 22, 1909.

Specification of Letters Patent.

Serial No. 484,921.

To all whom it may concern;

Be it known that I, TIMOTHY W. ANDER- son, a citizen of the United States, and a resident of Fort Smith, in the county of Sebastian and State of Arkansas, and whose post-office address is 1110 North Fifth street, have made certain new and useful Improvements in Locomotive Ash-Pans, of which the following is a specification.

My invention relates to improvements in ash-pans and applies more particularly to those ash-pans in use on locomotives, and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

The main object of my invention is to provide means whereby the ash-pan may be dumped and in which the warping of the pan proper does not necessarily interfere with the workings of the dumping mechanism.

A. further object of my invention is to provide an improved pan in which the joints are protected from the heat, thereby rendering them less liable to open and thus reducing the danger of lire from the glowing coals which are dropped through the open joints along the track.

A further object of my invention is to provide a mechanism simple in structure and economical in manufacture for accomplishing the above named objects.

Other objects and advantages will appear in the following specification and the novel features of the device will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings forming a part of the specification, in which similar reference characters indicate like parts in the several views and in which- Figure 1 is a side view showing an ashpan construction embodying my invention. Fig. 2 is a longitudinal section through the device. Fig. 3 is a bottom view and Fig. 4c is a perspective view showing the slide operating mechanism.

In carrying out my invention I provide a main frame A which is attached to the body of the locomotive (not shown). Although the invention is applicable to pans having a single compartment, I have shown in the drawing a pan B with a double compartment and a central space C for the entrance of the axle of the engine. The pan B may be formed with inclined sides I) or with vertical sides such as that shown at b and the pan is preferably suspended from the locomotive in the usual manner and is independent of the frame A.

At the bottom of the frame A I provide a pair of rails D, these rails consisting preferably of angle irons with their bottom portions turned inwardly toward each other, as shown in Fig. 4. Secured to the rails by means of rivets c or in any other suitable manner, are the rectangular members F. Each of these consists merely of a rectangular frame, the sides of which follow the contour of the particular pan to which it be longs, the bottom being open to permit the passage of ashes.

As will be seen from F 2 the ends of the receptacle B project within the frames F. There is, however, a space between the sides of the frames F and the sides of the ashpan. It will also be noted that the bottom of the ash-pan proper terminates above the bottom of the frames F in order to provide a space 9 at the bottom of the pan as well as at the sides.

Disposed upon the rails D are the slides S 'hich are connected by means of the links L. These slides may be formed of wrought iron, in which case they are strengthened by the angle irons K which are secured to the bottom, or they may be made of cast steel in which case the bottoms are provided with integral corrugations for the purpose of strengthening same. The slides S rest clirectly on the rails D and may be brought directly underneath the frames F or moved forwardly to uncover the latter. In the drawing, I have shown the means for accomplishing this as comprising a lever J on the end of a rock shaft M which has an arm 0 attached to a pivoted link P. Obviously other mechanism for moving the slides back and forth might be employed. The rock shaft M is secured to the frame by means of the bearing lug Q. The movement of the slides in a forward or backward direction is limited by the front and rear stops W and V respectively.

From the foregoing description of the various parts of the device the operation thereof may be readily understood.

From a study of Fig. 2 it will be seen that the bottom of the ash-pan proper does not touch the frames F which have considerable clearance. The slides S which form the bottoms of the ash-pan structure are also independent of the pans B proper. Thus it will be seen that even though the sides of the pans warp there will be no interference with the operation of the slide until the frames 'F have buckled or warped so that the move ment of the slide is hindered. This is not likely to occur, however, for the reason that the frames themselves are protected by means of the bottom of the ash-pan proper. The dead ashes accumulate in the space G between the frames and the lower ends of the pans and themselves form a heat resisting medium. It will be seen by this construction that the joints usually present are eliminated and there is not the danger of the opening of the joints and the spilling of the burning coals along the track, that exists in the ordinary type of ash-pan. The slides S being thus protected may be worked freely back and forth to dump the ashes as occasion requires and even after the bottoms of the receptacles B have warped to a considerable extent the dumping mechanism is in good working order. The contact surface between the slides S and the frame F is away from the heated pan and therefore these parts are not liable to spread so as to permit the ashes to drop down but will remain in close contact, thereby effectually preventing the danger of fire incident to the dropping of the heated coals along the track.

I am aware that other forms of the device based upon the same general idea might be made but I consider as my own all such modifications as fairly fall within the spirit and scope of the invention.

I claim:

1. In an asl1-pan construction, a receptacle having an opening in its bottom, a frame disposed about said receptacle and spaced therefrom, a portion of said frame being arranged to project below the lower edge of said receptacle, a pair of rails, a closure comprising a slide supported on said rails and arranged to move underneath said frame and to registerwith the opening in said receptacle, and means for reciprocating said slide.

2. In an ash-pan construction, a main support, rails carried thereby, a rectangular frame secured to said rails, a closure comprising a slide carried on said rails and ar ranged to project underneath said frame, means for reciprocating said slide carried by said support, and a receptacle arranged to project part way into said frame, the sides of the receptacle being spaced from the frame.

3. In an ash pan construction, a main support, rails carried thereby, a rectangular frame secured to said rails, a closure comprising a slide carried on said rails, and arranged to project underneath said frame, a lever for reciprocating said slide carried by said support, and a receptacle having an opening in its bottom carried by said main frame, and arranged to project part-way into said frame, the sides of the receptacle being spaced from the frame.
