IMPROVEMENT IN LOCOMOTIVE-ENGINES.

Specification forming part of Letters Patent No. 43,898, (lated August 23, 1864.

To all whom it may concern,.-

Be it known that I, Isaac H. GoNeDoN, of Springfield, in the county of Sangamon and State of Illinois, have invented a new and useful Improvement in the Smoke-Arch of a Locomotive-Engine, and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which-. L

Figure l is a front end view of my improved smoke-arch, the end Vpiece or plate being removed to expose the interior. Fig. 2 is a vertical section in the line xx.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in a novel and improved method of disposing of the sparks from the iire of an engine, in order to prevent them from flying or passing along the sides of the train into the faces of passengers or endangering the safety of property a-long the line of the railroad. My invention provides means whereby the sparks are caused to pass out through a conducting-pipe at the under side of the engine, and be submitted to the action of steam in such manner that they will be completely extinguished and rendered harmless before reaching the open air.

In order that others skilled in the art to which my invention appertains may be enabled to fullyl understand and' use the same, I will proceed to describe its construction and operation.

In the accompanying drawings, A may repsent a smoke-arch, which is to be located at the front end of an engine and receive the smoke, sparks, and other matter from the iixebox through tubes passing through the `boiler in customary manner. B is a sieve or spark-arrester, located within the arch A at a point in greater or less proximity with the top of the boiler and above the tubes o thereof, so that all smoke, sparks, and cinders from the tire-box must enter the arch A at points below the said spark-arrester.

O C are exhaust-pipes, which, in addition to their function of carrying oii' steam, are employed to inject the same into the arch A for the purpose of creating a vacuum within the same, and thereby producing the necessary draft for the tire through the boilertubes c. These pipes C C open within the arch just above the spark-arrester B, and the steam therefrom passes out of the arch at the opening A.

D D are jet-pipes communicating with the exhaust-pipes C C, and extending therefrom into a pipe, E, which extends from the converging or hopper-shaped box E to within, say, eight inches of the ground, said box E',

with its pipe E, being located at the forward end of the arch A. When the pipes C C are exhausting steam, a quantity thereof passes into the jet-pipes l) D, thence into the pipe E, from which it passes out at the underside of the engine. e

Now, it is manifest that whenV steam is injected from the exhaust-pipes C O into the arch A there is a tendency of the air to rush up through the discharge-pipe E to supply the vacuum, but the current which would pass up through this pipe E is overcome by the steam from the jet-pipes D D. Thus while the smoke is permitted to pass upward and out at the opening A, the sparks and cinders are arrested by the sieve B, and as the discharge of steam from the pipes D produces a contrary current in the direction of the pipe E,the said sparks and cinders descend into-the box E', and thence out 'upon the groundrthrough the pipe E. In passing through the pipe E the sparks and live cinders come Within the influence of the steam, by which they are deadened or extinguished, so that when they-are deposited upon the ground there will be no danger ot' the sleepers or other combustible material taking re therefrom. It will be seen that the currentv toward the pipes E will not permit anything from the fire-box to settle or accumulate within the arch A, and hence the latter will always remain in a clean condition and be preserved from the injury which might accrue from the lodgment of burning cinders or sparks.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-

Thejet-pipes D D, communieatingwith the exhaust-pipes C C, and employed, in conj unction with the hopper-shaped box E and discharge-pipe E, to cause the sparks, &c., to pass out and be deposited at the under side of the engine, and at the same time deaden or extinguish the same, substantially in the manner and for the purpose specified.
