ASH-PAN.

SPECIFICATION forming part of Letters Patent N 0. 791,185, dated May 30,1905.

I Application filed January 14, 190 1. $erial1lo. 189,029.

.To all whom it may concern:

Be it known that I, FRANK CRIS, a citizen of the United States, and a resident of Lima, in the county of Allen and State of Ohio, have invented a new and useful Improvement in Ash-Pans, of which the following is a specification.

My invention relates to an improvement in locomotive ash-pans, the object being to provide for the removal of ashes and cinders without the necessity of the usual raking which is performed by the fireman in cleaning out the ash-pan; and my invention consists means for simultaneously opening or closing the two sliding sections of the bottom of the'ash-pan by merely turning a shaft, which is arranged and intergeared to operate and control said sections from the cab of the locomotive.

My invention further consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a bottom plan view of my improvement in locomotive ash-pans detached from a 1000- motive and showing the sectional bottom in closed position. Fig. 2 is a top plan view of the same, showing the sections of the bottom.

in 0 en position, plate 19 being removed to disclhse the gear andracks. Fig. 3 is a vertical longitudinal sectional view taken on the line III III of Fig. 2. Fig. 4 is a detail view in cross-section, taken on the line IV IV of Fi 2, parts being omitted. Fig. 5 is a deta' view in cross-section on the line V V of Fig. 2, showing the saddle-plate and cooperangle-irons secured to the channel-irons and which extend some distance beyond the channel-irons at either end to form extension-tracks for the support of the sliding bottom plates when in open position. Connecte to the bottom sections 2 2 are the rods 5 5. Rod 5 is removably secured to a hollow depending lug 17, centrally located on the bottom plate 2, and rod 5 is removablyseoured to a similar lug at one side of the bottom plate 2, the last-named rod provided with an offset extension 5 the end of which is secured to a hollow lug on the opposite side of the bottom plate 2, the sides of the hollow lugs on plate 2 adapted to slidingly engage the angle-iron tracks 3 3 to guide the bottom plate 2 in its reciprocatory movement. The rods have rack-teeth 6 6 thereon at'their opposite ends and extend through a box 7, in which they are guided, a pinion 8 being located in said box and having its teeth in engagement with the rackteeth.

The box is supported upon a saddle-plate 1 8, Ushaped in cross-section, the ends of which plate are received and rest upon the angle-iron tracks 33, to which the late is seone side of the center of the saddle-plate, although this is not essential, the box comprising two lates 19 and 20, between which is journale a gear-wheel or pinion 8, and two guides 21 andv 22 are secured one on either side of the gear-wheel 8. Located intermediate the guides and on opposite sides of the gear-wheel 8 are the s ace-bars 23 23, which protect the gear-whee from injury and prevent the entrance into the box of material liable to impede or obstruct the operation of the mechanism. The bars 23 also serve to retain the box rigid and support the upper plate 19. The toothed ends of the rods 5 5 are received one on either side of the pinion 8, with which the teeth on the rods mesh, and the rear plane surfaces of the rods slidingly encured. The box 7 is preferably. ocated to gage the guides 21 and 22, which serve also in any suitable manner to the end of the rod, the opposite end of the gage extending over the top of the box 7, where it may be observed by the engineer or fireman to ascertain if the ash-pan is closed. In the event that the engineer should desire to' increase the draft he could open the bottom plates of the ash-pan a greater or less distance, as indicated by the gage. The gage also serves as a stop to limit the movement of the rod to which it is attached, by engagin the plate 19 when the rod is moved in one direction. A shaft 9, journaled in the box, carries the pinion 8. The upper end of the shaft preferably stops about flush with the floor of the locomotive and is angular to receive the removable shaft extension 10, which has a socket 1.1 on its lower end to it the angular upper end of shaft 9. This shaft extension has a Wheel 12 on the upper end, by which it is turned. In this way when it is desired to clean the ash-pan the extension is put in place on the upper end of shaft 9 and turned,

the bottom sections receding from each other simultaneously and letting fall the ashes between them, after which by reversing the direction of movement of the shaft extension the bottom plates are moved inwardly toward each other and the bottom closed.

To prevent ashes from catching between the bottom plates, the angle-iron tracks 3 3 terminate a short distance from each other at their inner*endssay six inches a artso that when the bottom sections 0 ose any ashes catching on these angle -irons are brushed aside and drop ed between the ends of the angle-irons in a vance of the bottom plates, thereby clearing the way and per mitting the bottom plates to come together at the center.

The sides 1 1 of the ash-pan are preferably braced and held apart by pipes or tubes 13 13, four in all, through which rods or bolts 14 14 extend, having nuts for securing them in lace, the nuts and heads being protected rom injury by the channeled sides.

Angle-irons 26 26 are located at the ends of the ash-pan, which angle-irons extend across from side to side .of the pan, and depending from these angle-irons are the perforated plates 15 15, forming the ends of the ash-pan, the lower edge of the lates 15 15 preferably terminatin about ha f an inch or so from the bottom pl ates 2 2 in order that there may be no scraping noise. These end plates serve to hold the ashes in the pan until the bottom plates have receded from one another far enough to permit the ashes to drop out of the pan. By having these end plates perforated they do not interfere with the draft when the engineer opens the damper.

The extreme ends of the tracks 3 3 opposite the saddle-box are upturned, as shown at 27, to limit the outward movement of the bottom plate 2, the engagement of the adjacent edges of the sliding plates 2 2, together with the engagement of the gage 24 with the plate 19, serving to limit the inward movement thereof.

From the foregoing it will be seen that I have provided a simple locomotive ash-pan which can be easily and quickly operated from the locomotive at a great saving of time and labor, while at the same time performing the operation most effectively. At the same time the cost of equipping a locomotive with my improvement is comparatively slight.

In some instances cast-iron may not be used, and I can therefore use sheet-iron plates, which will be braced by angle-irons, and in the event that steel should prove too expensive it is possible to form the toothed.

portion of the operating-rods of cast-iron, the teeth being formed on a bar received in a recess formed in the rods, as shown in the detail cross-sectional view.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I. do not wish to limit myself to the exact construction herein set forth; but, 0

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
