Letters .Patent No. 83,506, dated October` 27, V1868. n

`'.'Llae Schedule referred to in these Letters Patent and making part of the same.

To all whoml it may concern Be it known that I, J. A. .'IUsfrI, of Savannah, in the county of Chatham, and State of Georgia, have yinvented a new and useful Improvement in Locomotive Smoke-Stacks; and I do hereby declare that the following is afull, clear, and exact description thereof, which willenable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, 'in which the drawing represents a sectional elevation of my improved locomotive smoke-stack.

The object of this invention is to provide a locomotive smoke-stack with rsuch detaining-devices, that no coal, cinders, or sparks can pass through it with the escaping smoke, while the draught is not in the least impeded.

` The invention consists in the arrangement of the aforesaid detaining-devices, and more particularly in an annular grate, which will most eifectually prevent sparks from passing upward through the chimney.

A, in the drawing, represents the outer sheet-metal shell of a locomotive, said shell beingof ordinary-or suitable form and size, and secured in a suitable manner to the locomotive.

Through the lower end of the chimney, is fitted a smaller pipe, B, with an enlarged upper end, a,as shown.

This innev pipe extends upward, somewhat above the middle ef the chimney, and reaches also below the lower end of the same. The lower end of the chimney-case A is closed around the pipe B, by an annular plate, b.

O is a conical sheetmetal cap, fitted above the pipe B, and secured, by means of brackets'c, to the same., Its edge isv rounded and turned in, as in the drawing, and is about one inch lower than the upper edge of the The object of the cap C is to arrest the cinders and heavy substances that may arise in the smoke-pipe B, and to conduct those that may be carried over the edge of B to the annularspace d, formed around the lower part of the pipe B, above the plate b. From such annular space, the substances may be withdrawn through aA pipe, c.

D is an annular plate, fastened with its outer, higher edge to the shell'A, so as to be in contact with the same while its inner edge is lower, and is free from'contact with any other part of the apparatus.

The plate D will form an arrester or stop for such coal, sparks, or cinders, as may rise in 'the chimney along the shell A.. I E is a sheet-metal ring, inclined also, but in the opposite direction, asl); that is, its lower edge is the outer, and its upper edge the inner one. It is, by means of angle-irons fj', fastened to the shellvA, above the .ring I), as shown, its outer edge being about one inch distant irom the shell.

Its upper inner edge is bent downward, to 'arrest sparks that maybe blown up along its lower face, and it is distant from the shell, for the purpose ofallowing heavy substances from above to roll down on it, and on the ring D, to the lower part of the chimney.

F is aconieal cap, iitted over and above the ring E,

and resting upon brackets g g, that project from the shell, as shown. It has its edge turned in, to prevent sparks, dto., from being, by the draught, carried around the edge, and is about one inch distant from the inner side of the shell, as shown.

Upon the cap F rests an upright sheet-metal ring, G, which has angle-irons or feet h h, at its lower edge,

resting lon the cap F, as shown, so that, thereby, the

' being blown into the inner side of Gr.

l Near the lower edge is fastened, to the inner side of the ring G, by means of rivets or otherwise, a shorter ring, K, which is about one-sixteenth part of an inch distant from the ring G,and toA the inner side of K, is, in a similar manner, fastened another ring K1, and thus, seven, or more or less, rings K, K1, K2, 85o., arearranged, the inner one having its lower edge always `a little higher than the one to which it isfastened. The .innermost ring, K4, is attached to the under lside of a plate, H, which has a nm, l, projecting beyond K4, as shown. A p

The distance between the various rings K, K2, 85o., is determined by means of washers interposed between them.

Instead of being separate rings, this grate, Ktc., can be formed by one narrow band woimd spirally in the requisite form, the windings being about one-sixteenth of an inch apart nom each other, and gradually rising, as shown. Sparks cannot readily pass through this' grating, and if they do, they will be arrested by the projecting flange l, or by the cover of the shell.

The covering-plated of the shell has a central aperture, around ,which an upward-projecting tring, m, is arranged. Said ring is made of open-work, as shown, and has its upper part outward bent. to secure an uninterrupted draught.

Across the central aperture-.otl the plate z', is fitted a cross, n, from which a bolt or screw, o, is suspended, for connecting the cap, F, with the plate H, in the manner shown. l

Under the plate i, projects around' the central aperture, downward and outward, an annular plate, p, for

arresting sparks that may have succeeded in arriving above the plate H.

It will be noticed that it is almost an impossibility for a spark or ashes to issue from the 'orifice of the smoke-stack, and an actual impossibility for coal or cinders.

Having thus described my invention,
