To all/whom# may concern:

Be it known that we, WASHINGTON A. PEASLEE and JOHN O. D. LILLY, of Indianapolis, in the county of Marion and State of Indiana, have invented a new an'd useful `Improvement in Chimneys and Spark-Arresters for Locomotives; and we hereby declare that the following is a full' and exact description.

The nature of our invention consists in providing a perforated spark and` smoke cone-within the chimney stack properand forcing, or drawing all the products of combustion through the perforations by a centrifugal action given to said products by means of a` continuous current of exhaust steam passed up along the outside of this side of the chimney. In this way, a more` perfect and uniform exhaust is kept up and mlaintained, than'by any of the other known ans. p To enable others, skilled in the art, to manufacture and use our invention, wewill now proceed to describeits construction and operation.

Figure l, is an elevation of chimney and smoke arch, box, or reservoir, (viewed from the standpoint of the engineer in his cab) showing themanner in` which the exhaust pipes enter the said chimney-also the waste pipe for redundant sparks, that are arrested in their outward` passage. i Fig. 2, is an elevated view ofthe perforated cone, through which all the products of combustion` make their escape.` Fig. 3, is an elevated sectional view of the chimney,perforated cena-waste spark tuba-saddle for chimney, and all else pertaining to the device. Fig.4, is aview of the chimney saddle, and the lower inclined planes-by means of which the `escape throat is enlarged, or di,- minished, at the will of the engineer. Fig. 5, is an elevated view of the collar which surrounds the escape throat, and which also supports the outer chimney case.` Fig. 6 is an elevated view ofthe above collar propershowing the pins and, by dotted` lines the inclined slots in which these pins play, to

elevate, or depress the chimney. Fig. 7, is`

a top viewof the chimney and the perforatedcone within. Fig. 8` is an underside view of the saddle showing the manner in which the exhaust pipes enter it;\\als othe relative` position of the tube, for waste` sparks, to these exhaust steam pipes.`

Inthe following description, the saine let:-` ters always refer to like parts.; to` wit:

The supplementary exhaust collars `c,agnflf` l 1 e, are` so arranged astoiallowfthe exhaustf .l steam to pass up between them` the exhaust steam bein first admitted underneath them,"` in the sad leB, threugh` the two pipesfs, 18,5 n and from thence distributed around the@ eni 119 tire circumference of the collane, betweeir` l` it and the collar, 0,-`thencepassing.ummpdg` 1" between the perforated cone D, and the external stack C', to the place of egress at the top of chimney. l

d', andV d', are pins projecting from the collar, c, these pins sliding in the inclinejlane slots, indicated by the dotted lines in s, s, being the steam exhaust pipesthese passing u into the saddle B through the smoke arc i, (from lateral points,) having their termination in an annular space surrounding the base of the perforated cone D-the direction the steam takes is indicated by the double barbed arrows-thus in contradistinction to the direction of the products of combustion, as indicated by the single barbed arrows.

By reference F to Fig. 3, it will be seen that there is an adjustable throator annular outlet for the steam, in passing from the exhaust pipes, s, s,-which is marked by the letters T, T; this throat can be enlarged, or contracted by the rotation of theV saddle collar c, through the intervention of lever h; passing it to the left, lifts the chimney, or smoke stack-and thus contracts the said Athroat; while passing to the right, lowers one on the immovable projection of saddle B, and the other on the inside of collar c. Now, when collar, c, is dropped below the other, the throat for the passage of steam is enlarged, but, when raised so as to bring these projections opposite, the said steam throat is contracted to its smallest dimensions.

The advantages we claim for this invention over all others, constitute to some extent its plea of novelty in an economical point of view;-its philosophical adaptation to the functions it has to perform, completes-as we verily believeits claims to superior novelty and practical usefulness over any and all other locomotive chimneys.

These points are more fully explained in the following description of the operation of our invention: viz: The flame, and products of combustion, pass up into the perforated cone D, around the spark waste pipe, s, and escape from this cone into the steam chamber-centrifugally-and, thence up and out at the top of chimney, C. The exhaust steam passes up the pipes-s, s,- through the throat T, into the annular space, around the perforated cone, (and within the chimney C,) to the place of egress at the top of same.

Now we are aware that it is no new thing to form a draft of air for the more perfect riddance of smoke, sparks, &c., by means of a current of steam, as experiments in Ewbanks Hydraulics amd Mechanics are delineated, where steam is used for the elevation of water 1ttc., but, in all such experiments the steam is passed up through a central tube, or nozzle, the draft acting upon a substance or substances on the outside of said current of steam. This peculiar feature of all known plans, similar to this, is

mentioned, in order that the real operation,

or rationale, of our mode of producing a draft, 'may be more fully comprehended. We pass the steam up, on th'e outside of the smoke, sparks, &`c., and by so doing .we not only bring a larger proportion of steam to bear upon these products of combustionthan the reverse planY would do*but, by surrounding the escaping sparks &c. with steam we eectually drown out and extinguish all supernatant sparks, &c. The aldvantages of this are self-evident. In this arrangement of ours, the steam is forced upV the chimney with such a velocity as to suck, or draw the air, smoke, &c. from the furnace, through the flues, and up the perforated cone, and thence out at the top of chimney through the perforations-as indicated by the course of the single barbed arrows. Y Y

When we desire to raise steam, in an yengine boiler speedily, we simply rotate the collar, c, so as to contract the throat T, and, when a sufficient supply is produced We rotate it back and so enlarge this steam throat to suit the exigencies.

To prevent the condensation of steam in the `chimney (and consequently to prevent a retardation of its velocity) we contemplate surrounding the chimney C, with a wooden jacket during cold weather. This is not shown in our model or drawings, and, of course is optional with the users, and, in equatorial localities is not needed at all.

Observe the tunnel S, at the top of spark tube S, and the direction of the curved arrows over it. These arrows indicate the direction of supernatant and large sparkstoo large to escape through the perforations of the cone D. As they are drawn up the coneseeking egress into the steam channel without-they strike the pyramidal apex of said cone, and so, with a rebound, are caused to drop back into the tunnel S, and thence by their own gravity (being away now from the drawing influences of the steam) drop down through the tube S, into the bath box b, where, a constant supply of water drowns them out.

We are aware that returning sparks simply from the top ofthe chimney, is not new, but, no one has hitherto returned them in such way as toutterly preclude the possibility of choking the tube which conducts them-our tube passing down perpendicularly, while others pass at an angle of fortyve degrees-and, at the same time, are necessarily much longer. l

In applying our invention to any common locomotive, no cutting, or mutilation is required, more than simply the cutting of two holes for the egress of the steam pipes s, s, as seen in Fig. 8. These holes are covered and guarded `by the cast-iron saddle B. The chimney is simple in construction, light in Weight, cheap, and besides performing the functions of a most perfect draft for the fire and spark arrester, and extinguisher, (all of which it performs in a superior degree) is durable to an extent equaled only by its exact adaptation to the purposes for which it is designed.

Having now described our invention in 15p full, what We claim asnevv, and desire to secure by Letters Patentis`f` V The constructionl ofa ch' lney, or spark arrester, by the `combination andarrangement of the various parts,substantially asgzp they are described in the foregoing specifica-,U v tion, and for the purposes mentioned. y i
