aac-oca Specification 0f Letters Patent. Patented June 27, 191 1 Application filed December 13, 1909. Serial No. 532,929.

To all whom it may concern:

Be it known that I, Rosoon B. KnNnro, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Ash-Pans, otl which the following is a specification.

The invention relates to improvements in locomotive ash pans, and particularly to the means for supplying air thereto. The invention has tor its primary objects; the provision of an improved attachment whereby the supply ot air to the ash pan is augmented when the locomotive is in motion; the provision of means of the character specilied whereby the supply of air is uniformly distril'n'lted along the length of the ash pan; the provision ot' an attachment oit the character specified which will not interfere with the flow of air to the ash pan when the locomotive is stationary, or running at slow speed; and the provision oit' a simple and clfectve attachment which may be applied to the majority of locomotives now in use. One embodiment of the invention is illustrated in the accompanying drawings, whereinz- Figure 1 is a horizontal sectional view taken through the rear end of the locomotive alcove the improvement constituting my invention,

Figure 2 is a partial side elevation ot a locomotive with the improvement applied thereto, and

Figure 3 is a partial transverse section through the tire-box and ash pan on the line III- III of Figure 2, and a partial rear elevation of the locomotive with the attachment applied thereto.

The improvement is particularly desirable in the case of engines with wide or semiwide tire-boxes, in which the inclined hottom of the ash pan limits the size of the air admission slots or passages so that the supply of air under certain conditions is insu'tl'icient, particularly at high speeds. At such times the tendency is to draw the air outwardly through the admission passages, thus giving a slight degree of vacuum in the ash pan, retarding the combustion, and giving a down draft and resultant tendency to lourn out the grates when the door of the tire-box is opened. My improvement is designed to meet these conditions, and, briefly stated, comprises deflection means arranged along t-he admission openings at the sides ot' the ash pan and adapted to deflect the air inwardly through the admission openings on the ljorward movement ot the locolnotive.

The drawings illust-rate only so much of the locomotive as is necessary to indicate the location oil my improvement and the method of its application. Rcilcrring particularly to Figure 3, 1 is the tire-box of the locomotive, provided with the gratos 2; 3 is the water leg provided at its lower edge with the usual mud ring zl; 5 the grate frame which may he oil any approved construction; and (S is the inclined bottom plate ol the ash pan.

An extended slot or passage 7 is provided along the upper edge ot the ash pan on each side thereo't, the grate iframe and plate (l heing spaced apart and maintained in position hy means ot the usual holts S and spacing tuhes t). Opposite thisl slot or passage 7 on each side ot the ash pan is the detlecting means constituting' my improvcnlent. This means is a box-like construction con'iprising a pair oit opposing plates 10 and 11 secured to the mud ring -jl and plate (i respectively hy means ol" the studs 19 and holts 8, and carrying a series ot :torwardly inclined vanes 13, 14k, 15, 16 and 17. 'lhe plates 10 and 11 diverge as indicated in Figure 3 in order to increase the capacity el. the vanes and the successive vanes, 'from lront to rear, are ot gradually increasing size in order that each vane may have a portion which is unshielded by thc preceding vane. The air supplied is thus distributed along the length of the passages and the capacity of the de'tlector correspondingly increased. The curve on which the dellecting surfaces or vanes are lient is such that a maximum inflow ot air is secured with the least resistance to the 'torward moven'lent of the device, hut it will he apparent that various arrangements oi; uellectors and various other angles might he substituted. The device as shown is constructed ot sheet metal and is adapted to he im'lnu't'actured as an attachment and applied to locomotives as now constructed, the present locomotive structure being such that the attachment may he readily applied.

The method of operation and utility of the device will he apparent :from the foregoing. The intlow oit air secured by the de- `llectors increases with the speed ot the locomotive, and when the locomotive is running at slow speed or is stationary the attachment interferes in no way with the inflow of air through the passages 7. No damper or regulator is ordinarily necessary for controlling the iiow of air through the passages 7 as the supply of air under no condition is excessive, and even when the air pressure on one side of the locomotive is greater than that on the other side the opposing currents from the two slots or passages 7 cooperate in such a-way that no undesirable results follow, are additional flow on one side merely tending to reduce the inflow through the opposite passage or slot.

y Having thus described my invention and illustrated its use what I claim as new and desire to secure by Letters Patent is the following Y l. A locomotive ash pan having admission means formed to admit a substantially coning a box open at its outer side and communicating with the admission means at its inner side and provided with a plurality of forwardly inclined vanes.

3. An attachment for application to the air admission means at the side of a locomotive ash pan, comprising a box open along its inner and outer sides and having its upper and lower sides inclined to approach each other at the inner side of the box, and provided with a plurality of forwardly inclined deflecting vanes.

et. The combination with a locomotive ash pan having air admission means along the side thereof, of means for deflecting air through such admission means on the forward movement of the locomotive comprising a box open at its outer side and communicating with the admission means at its inner side and provided with a plurality of forwardly inclined vanes increasing in length from front to rear.

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