SAMUEL L. FRENCH AND RICHARD B. MELLON, OF LIGONIER, PA.

SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 245,621, dated August 16, 1881.

Application filed May 25, 1881. (No model.)

To all whom it may concern Be it known that we, SAMUEL L. FRENCH and RICHARD B. MELLoN, citizens of the United States of America, residing at Ligonier, in the county of WVestmoreland and State of Pennsylvania,have invented certain new and usefullmprovements in Spark-Arresters; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a side view of the front portion of a locomotive, showing a central sectional view of our improved spark-arrester. Fig. 2

is a perspective view thereof, and Fig. 3 is a detail view of the same.

This invention has relation to improvements in spark-arresters attached to the chimney of locomotives or portable engines; and its object is to prevent the escape of the sparks from the engine-fire to the open air, and providing a means of collecting and conducting them to a receptacle on the front of the locomotive or engine. I

Our improvement, therefore, consists in perforating the funnel of the smoke-stack and attaching to the outside a funnel-shaped receptacle, with the smoke-stack enveloped by and extending through the side of the funnel, so as to throw the escape entirely outside and to the front of the stack.

Ourimprovementfurtherconsistsinthenovel arrangement and combination of the parts, as will be hereinafter more specifically set forth and claimed.

The letter A represents the chimney, of the usual construction, formed with the extending sleeve B, runninginside and beyond the junction of the chimney with the swell of the stack. On the tongue of this sleeve arefixed rigidly the standards a, to which is secured the cone 0, suspended with the apex down and over the center of the aperture of the chimney. The object of this cone is to deflect the cinders or sparks as they emerge from the chimney against the wire screen, from whence they are thrown to the perforated funnel D. The funnel D is secured in the swell of the stack, and must be raised above the floor of the funnel, to which it is fastened at the top edges. It is supplied with two or more large holes, in addition to the regular perforations, for the purpose of permitting the egress of larger cinders which may be thrown up from the pipe.

The letter E represents the funnel attached to the outside of the lower section of the swell of the chimney, andformed so that the chimney passes through one side of the funnel, and is surrounded or enveloped by the metal of the funnel, and the escape thrown clear of the chimney and in front of it, substantially as seen in the drawings. (See Fig. 1.)

TheletterFshowsametallicconducting-pipe secured to the small end of the funnel E, and from thence extending to and opening into the top of the ash or cinder box G, which is mounted on a platform fixed in front of the stack or boiler, and provided with hopper-shaped bottom and sliding or hinged discharge door H, through which the refuse can be dropped out. This cinder-box is made of sufficient size to meet the requirements of the engine or the length of the trip to be run.

This improvement may be attached to the common chimney of a locomotive by connecting or riveting the funnel E to the swell of the chimney, and forcing the extending sleeve B, with the deflector, to the top of the pipe, the other parts being arranged as before described.

It will be observed that the courseof operation will be as follows: As the draft throws up the sparks and cinders they strike the deflector, and from thence pass to the screen of the chimney, and are thrown downward in the perforated funnel, through which they pass to the basin of the funnel E, and thence down the pipe into the box, and may be withdrawn from there at pleasure.

It is obvious that slight changes may be made in the construction of the parts and the arrangement of the same without departing from the spirit of our invention.

What we claim as our invention, and desire to secure by Letters Patent,is

1. The combination, with a smoke-stack, of In testimony whereof we affix our signatures an irregular-shaped funnel, E, attached to and in presence of two witnesses.
