Specification of Letters Patent.

Patented Sept. 29, 1914..

Application filed January 21, 1914. Serial No. 813,543.

To aZZ whom it may concern:

Be it known that I, JAMES lVARE WILLING, a citizen of the United States, residing at N anticoke, in the county of Wicomico and State of Maryland, have invented certain new and useful Improvements in Spark- Arresters, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in spark arresters and. more particularly to a device of the above class which is adapted for application to smoke stacks of locomotives or other stacks of similar character, the main object of the invention being to provide a device of this character which may be quickly and readily applied to the top of the smoke stack for receiving the cinders and other particles passing from the stack and to convey them downwardly and out beneath the engine bed to any desired place.

Another object of the present invention is the provision of a spark arrester of the above character which will possess advantages in points of efliciency and durability, is inexpensive to manufacture and, at the same time, is simple in construction and operation.

lVith the above and other objects in View, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawings forming a part of this application, Figure 1 is a side elevation of a spark arrester constructed in accordance with my invention. Fig. 2 is a vertical sectional view; and Fig. 3 is a horizontal sectional view taken on the line 33, lig. 1.

Referring more particularly to the drawings, 1 indicates a smoke stack of any gen eral construction, to the upper end of which my improved spark arrester is to be removably applied.

lhe spark arrester in itself consists of a hood or cowl, as generally indicated by the numeral 2 and is formed of a fine mesh screen wire of a suitable size, so that the same will fit various sizes of stacks. The lower end of the hood 2 is preferably cut so that the same is disposed at an angle, as indicated at 3 and secured to the lower edge of the hood, is a resilient trough 4:, to the .the numeral 5,

riveted or otherwise secured upper and outer edge of which is secured the lower edge of the hood, as indicated by the same being secured preferably by rivets or othersimilar fastening means.

' The trough 4 is preferably constructed of resilient metal so that when the hood is applied to the smoke stack, the inner edge of the trough may be curled upwardly and bent inwardlyand is of'suiiicientresiliency so that the same may be applied to stacks of various sizes, the inner edge being curved according to the size of the stack.

The trough 4 communicates at the lowest point of the inclination 3, with a drain pipe indicated by the numeral 6, and which is to extend downwardly and open, if applied to a locomotive smoke stack, beneath the body of the locomotive, so that the cinders may be conveyed to the track bed. The hood 2 is further supported in position by means of the standards 7, the lower ends of which are to the trough 4 and the other ends thereof secured in any suitable manner to the upper ends of the hood. From this, it will be seen that the standard 7 may be retained in an upright position, so as to securely retain the hood in its effective shape. 7

From the above description taken in connection with the accompanying drawings, it will be readily apparent that I have provided a spark arrester which may be readily applied to smoke stacks of various sizes and which will, at the same time, arrest cinders and sparks and convey them to the road bed or any other desired place.

It will also be apparent that my device can be quickly and readily applied to smoke stacks of various sizes and retained in such position by means of the resilient trough 4. Thehood 2 will also be supported in its effective position by means of the drain pipe 6. This pipe is preferably formed in sections, telescopically engaged, so that the hood may be readily removed and placed upon the smoke stack without interfering with the position of the drain pipe.

It will also be apparent that I have provided a simple and durable spark arrester which is extremely simple in construction and can be manufactured and placed on the market at a comparatively small cost.

While I have shown and described the preferred form of my invention, it will be obvious that various changes in the details gagement with the stack, as and for the.

purpose set forth.

2. A device of the class described including a hood having an opening adapted to receive a smoke-stack, and a resilient flange arranged around said opening, whereby when the stack is placed within said opening, the inner edge of the flange will resiliently engage the stack to retain the hood in position thereon.

8. A device of the class described including a hood having an opening therein adapted to receive a smoke-stack, and a resilient fiange around said opening and adapted to engage the smoke-stack, whereby various sizes of stacks may be disposed within said opening.

In testimony whereof I hereunto aiiix my signature in the presence of two witnesses.

JAMES W. WILLING.
