Specification of Letters Patent.
Application led August 2, 1912.

serial No. 712,857.
T0 all whom it may concern:
Be it known that I, CHRISTOPHER A. `CARD- WELL, a citizen of the United States, residing at Concord Depot, in the county of Appomattox and State of Virginia, have invented new and useful Improvements in Spark- Arresters, of which the following is a specification.
This invention relates to improvements `in spark arresters, and more particularly to a device of this character to be applied to locomotives, traction engines, threshing Inachines and heaters of all descriptions.
Itis the object of this invention to provide a simple and efficient device which can be readily applied to the smoke stacks of steam engines, which will prevent the discharge of sparks and cinders and yet not lessen the draft from the fire.
While the preferred forms are illustrated on the accompanying sheet of drawing, yet it is to be understood that minor detail changes may be made without departing from the scope thereof.
Figure 1 is a view in front elevation of the spark arrester as contemplated. Fig. 2 is a view in end elevation. Fig. 3 is a view in end elevation of a modified form of outlet. Fig. 4 is a view in central longitudinal section. Fig. 5 is a view in central transverse section.
The spark arrester as contemplated in this invention comprises a drum or hood 1 of the shape of a frustum of a cone having an elliptical cross section with its bottom 2 closed and of a contour corresponding to the boiler 3 upon which it rests. As shown.` the side walls slope upwardly and the top is provided with a hinged cover 4 having upwardly sloping walls and a central discharge stack 5. The bottom is provided with a central opening of sufficient size to receive the ordinary stack flange 6 of the boiler 3. An internal intake sleeve 7 is secured about the opening extending upwardly within the drum 1 for conveying the smoke from the boiler. The sleeve is secured in place at the upper end by a band S and braces 9 therefrom to the walls of the drum. For arresting sparks and cinders issuing from the sleeve 7 a pair of removable gratings are supported above the upper opening. Each grate 10 comprises a straight bottom member 11 and a curved upper member 12 with a plurality of grate bars therebetween. The bottoms are centrally supported above the sleeve 7 by means of forked brackets 13 secured to the braces 9 at the walls of the drum. The bottom member 11 of one grate is preferably provided with an angular eX- tension 14 upon which rests the bottom member of the other grate. The gratings 10 are curved outwardly, as shown in Fig. 4, to rest upon the inner edge of the top of the drum 1, and are groo-ved on their under side.
As the bars in the gratings are relatively small and close together all sparks and cinders will be deflected to the sides of the drum and collected in the lower ends of the bottom. To removethe dead ashes a vertically sliding door 15 may be utilized, as illustrated in Figs. 1 and 2, and left hand of Fig. 4, or a cylindrical outlet 16 adapted to connect with a waste pipe may be employed having a swinging damper or clo-sure 17, operable by a cord leading to a point convenient to the engineer, as shown in Figs. 1, 3 and 4. To rapidly cool the deflected ash as it is collected in the bottom of the drum, the drum is mounted upon four depending legs 18 which rest upon the surface of the boiler 3 and provide a space therebetween for the circulation of air.
The cover being hinged, it is readily opened and the grates removed for the purpose of cleaning when necessary. The top of the discharge stack being about the same height as the ordinary stack with the enlarged space of gratings above the discharge of the sleeve the amount of draft is not reduced. If desired curved deiectors 19 may be provided between each grating and side wall to direct sparks or coals, issuing from the sleeve or deflected by the grating, toward the bottom.
V`What I claim is:
In a spark arrester, a drum having a curved bottom supported upon legs above the boiler and inclined Walls, an intake lower portions provided With apertures with sleeve, a plurality of removable inclined closures for the removal of dead ashes.
atinvs centrali su orted above the ntgzl'ke the bottomyof Eile grating engaging CHRISTOPHER A' CARDWELL' 5 supports on opposite side Walls and support- Witnesses:
ing the other grating, and a cover having a L. B. FRANKLIN, discharge stack and the side Walls of the C. B. CROSS.
Naples of this patent may be obtained for ve cents each, byV addressing the Commissioner of Patents,
Washington, ID. C.
