LOCOIVlOTlVE ASH-PAN.

SPECIFICATION forming part of Letters Patent No. 242,430, datect'J'une 7, 1881.

Application filed July 9, 1880. (No model.)

To all whom it may concern:

Be it known that I, JAMES GARRISON Bor- TERFIELD, of Sioux City, in the county of Woodbury and State of Iowa, have made certain Improvements in Ash Pans and Fire- Boxes of Locomotives, &c., of which the following is a specification.

This invention relates to the ash-pans and fire-boxes of locomotives, &c.; and it consists in the arrangement of the grates upon a downwardly curved deflecting plate or support above a hollow ash-pan, whereby the falling cinders and ashes are caught and prevented from escaping, and the draft deflected downward and upward before it strikes the grate, as hereinafter set forth.

The invention further consists in hingingone end of the ash-pan, so that it may be adjusted higher or lower, or the pan cleaned from the outside, as hereinafter set forth.

The invention further consists in making the flaring ash-pan adjustable higher or lower by means of cams or similar devices, as hereinafter set forth.

The invention further consists in forming the coal-burning-grate support, cinder-chute, and deflecting-plate all in one piece of cast-iron, substantially as set forth.

I accomplish these results by the use of the mechanism illustrated by the accompanying drawings, in which- Figure I is a plan view in section, the up per half on the line at x of Fig. II, and the lower half on the line y y of Fig. II. Fig. II is a longitudinal section, and Fig. III is a crosssection of the lower part of the fire-box and the ash-pit of a locomotive, showing my invention when applied to both coal and wood burners, the right-hand side showing the coal-burning grate, and theleft-hand side showing the woodburning grate.

A is the water-leg or lower part of the boiler, surrounding the fire-box; and B, the ash-pit, having the usual hinged dampers, a a.

O is an ash-pan, made with flaring sides and ends, I) I), and mounted either upon feet 0 or cams (I, one of each being shown, so that the pan may be suspended, either rigidly or adjustably, some distance above the bottom of the ash-pit, as hereinafter explained.

Above the ash-pan O is a downweirdly-curved deflecting or supporting plate, E, resting upon the projecting edge of the ash-pit B, and when coal-burnin g grates F are used this curved plate will be provided with an inclined top, E in which the grate-bars are pivoted, as shown, and when used for burning wood a flange or rib, d, will be formed upon the top of the curved plate, to retain the grate-bars F in place.

In both forms of the deflecting-plate the space between it and the leg A of the boiler will be filled with fire-clay, or other non-conducting material, to counteract any bad influences cold air might exert by entering at these points.

When the coal-grates are used holes h are left .in the top E of the plate E, through which the fire-clay is inserted.

The grate-bars may be made in any desired style or form, the bars F on the right-hand side of the ligures being of the ordinary rock ing pattern used in coal-burnin g locomotives, while the bars F on the left-hand side are the ordinary wood-burning pattern, the only change required to use either being in the form of the upper side of the deflectin g-plate E.

The forward end, I), of the ash-pan G will be hinged at (1 and provided with a system of levers, c e c 6 so that it may be dropped down to enable the cinders and ashes to be removed through the damper a.

By these arrangements of the deflectingpla-te E, grates F or F and ash-pan 0, all danger from escaping sparks orlive cinders is avoided, as none can get out over the flaring edges of the pan 0, while the curved plate E turns them all into the pan.

A large percentage of partially-burned coal falls through the grates into the ash-pan O, and is ordinarily wasted; but by this arrangement the entering air is deflected downward by the curved plate E before it passes upward through the grates, and acts upon the burning cinders and keeps them alive until they are entirely consumed, thus greatly economizin g in fuel, as this combustion-adds somewhat to the heat of the furnace, as well as to heat the air before itenters through the grates to form a hot blast. This will be found very advantageous in cold weather.

The centers of each of the sections of the rocking grates F will be provided with hangers m, projecting downward and connected to each other by a bar, a, so that they may be oscillated in concert.

H is a lever pivoted to the connecting-bar a, and passing out through the lower part of the deflecting-plate E and leg A, and adapted to be vibrated by a lever, H, from the cab of the locomotive, to oscillate the grate-bars I in clearing them of ashes, cinders, &c.

Where the lever H passes through the plate IE it is surrounded with a steam and water tight bushing, t, to prevent leakage at this point.

I am aware thatit is not new to oscillate the bars F by levers running through the side or bottom of the ash-pan and attached to one side ot'thegrate-bars; but, so far asIam aware, none has ever been used with the operatinglever attached to the center of the grate-bars, and passing out through the leg of the boiler at a point very nearly on a line with the connecting-bar a, by which means the strain is evenly distributed over all parts of the bars, and the line of angularity of the lever H greatly reduced, whereby the grates are oscillated with much less expenditure of force, and with less strain upon the parts; hence they may be made with less metal to produce the same results.

The ash pan 0 is shown with one end mounted upon a stationary standard, 0, while the other is supported by an adjustable cam, (I. In some cases it may be found advantageous to use either method of supporting the pan; hence I do not wish to confine myself to either.

I am aware that it is not new touse a curved deflectingplate in connection with atlaringsided solid ash-pan but none, so far as I am aware, show them in connection with grates or the adjustable end or ends b of the ash-pan.

I am aware of the patent granted to Farley, No. 134,741; but he shows no grate-bar, his object being, mainly, to afford a means of protection from snow, &c. I do not claim any such construction, as the grate-bar forms an important element in my combination but What I do claim as new, and desire to secure by Letters Patent, is-- 1. The combination and arrangement, with the grates F or F, of the downwardly-deflectin g supporting-plateE and the ash-pan 0,1121"- ing flaring sides I) b, substantially as and for the purpose set forth.

2. The ash-pan 0, having the inclined sides and ends b b, with one or more of said sides or ends b "erticall y adjustable, in combination with the downwardly-curved deflecting-plate E, substantially as set forth.

3. The pan 0, mounted upon cams or similar devices (1, whereby it may be adjusted higher orlower,in combination with the grates F F and the downwardlydetlectingsupporting-plate E, substantially as and for the pun pose set forth.

4. The ash-pan (1, having the flaring sides and ends, with one or more of said sides or ends, 1), adjustable, in combination with the le vers e c c 6, arranged and operating substantially as hereinbet'ore set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

JAMES GARRISON BUTTERFIELD.
