CINDER A Application filed August 5,

This invention relates to improvements in cinder arresters for coal burning locomotives.

The primary object of the invention is'to provide an attachment for locomotives for deflecting the cinders as they pass out through. the stack to prevent them from entering the cars behind and for preventing hot cinders and sparks from causing damage by fire to property along railroads.

Another object of the invention is to provide a cinder arrester including a hood mounted above and behind the smoke stack of a locomotive for trapping the cinders as they pass from the smoke stack, there being an opening in the rear wall of the hood for the escape of the trapped cinders and a baffle member partially encircling the boiler of the locomotive rearward of the hood to deflect the cinders to cause them to drop to the road bed.

A further object is the provision of a cinder arrester which is simple in construction and n which may be applied to locomotives now in use without requiring any change in construction thereof.

With these and other objects in view, the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which V Figure 1 is a side elevation of a locomotive with my improved cinder arrester thereon.

Figure 2 is an enlarged vertical sectional view through the cinder arrester.

Figure 3 is a vertical transverse sectional view on the line 3-3 of Figure 2. r

Figure 4 is a detail perspective view of the baflie member.

Figure 5 is a detail perspective View of the hood.

Referring more particularly tothe draw ing, the reference numeral designates a locomotive of the coal burning type which includes the usual boiler 11 and smoke stack 12. My improved cinder arrester includes two elements, namely a hood 13 and a bafile member 14. V r

The hood 13 comprises an annular ring 15 which fits snugly about the smoke stack 12 andwhich is secured thereto in any suitable manner such as by bolts or rivets 15. Formed integral with the ring 15 is a casing 16 which Bnonn, new Yong.

through an opening 20 in the rear side wall.

The bottom edge of the hood 'member is shaped to fit snugly against the boiler 11 buthas a portion of the edge spaced from the boiler to form the opening 20.

' The baffle member 14 comprises a segmental vertical wall 21 from which an attaching flange 22 extends and lies flat against the outsideof the boiler 11; Bolts or rivets 23 pass through the flange 22 and boiler for securing the battle memberthereto. A bafiie flange or horizontal wall 24 extends from the vertical wall 21 at a right angle thereto and is curved ,to lie in even spaced relation to the boiler.

The ends of the baffle member terminate below the horizontal axis of the boiler toprevent any possibility of the cinders escaping to the rea i In practice, the sparks and cinders from the engine or locomotive pass out of the smoke stack and are trapped within the hood 13 which has an'open front for the escape of smoke and for creating a draft through the hood and opening 20 when the locomotive is in motion. The cinders pass through the opening 20 and are deflected by the walls 21" and 24 of the baffle member so as to drop downward upon the road bed. It will be appreciated that my invention will eliminate The rear side of wall the inconvenience of cinders entering the passenger cars of a train and will also reduce the fire hazard along a railroad, caused by sparks from the engine alighting upon adjacent property.
