SMOKE-STACK FOR LOCOMOTIVE-ENGINE HOUSES.

Specification of Letters Patent No. 23,825, dated May 3, 1859.

To all whom it may concern:

Be it known that I, H. CLAYTON, of Tamaqua, in the county of Schuylkill and State of Pennsylvania, have invented a new and Improved Arrangement of Stacks or Flues for Carrying Off the Smoke from Locomotives in Locomotive-Houses; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawmgs, making a part of this specification, in which Figure 1 is a view of a locomotive house, partly in section, with my invention applied to it. Fig. 2 isa detached and enlarged sectional view of a portion of the stack or flue.

Similar letters of reference denote like parts in both figures.

To enable others to fully understand and construct my invention, I will proceed to describe it.

A, represents a locomotive house which may be of usual construction, and B '18 a cupola having slatted windows or openings to allow the escape of smoke and still keep out the storm.

C, is a vertical smoke pipe or stack, the upper end of which enters the cupola B, and the lower end of which extends down within the building a suitable distance, and has a series of flues D, communicating with it, said flues being somewhat inclined and having each a short vertical tube a, attached, about equal in diameter or a little larger than the flues. In each tube a, is fitted a sliding tube 1), and these latter tubes are provided at their lower ends wit-h funnel-shaped caps c, as shown clearly in both figures, and to the upper end of each tube 6, a rope d, is attached; said ropes passing over pulleys c, and having counterpoises f, at their lower ends. The flues D, are so arranged that each tube 5, will be in line with the smoke pipe of a locomotive when the latter is within the house and occupies its proper place; see Fig. 1, in which a locomotive is shown in its proper location, and having its smoke-pipe in line with a cap of one of the flues. Each tube 6, has an opening 9, made in it; said openings being equal in diameter to, the flues, see Fig. 2.

The engineer previous to kindling the fire, lowers the tube 6, that is directly over the smoke pipe of his locomotive, and when said tube is fully lowered, its opening 9, will be in line with its flue D, so that a direct draft will be had into or through the stack O, and the smoke will be conveyed into the cupola B. When steam is generated, and previous to the locomotive leaving the house, the engineer or attendant shoves up the tube 6, as shown in red in Fig. 2, so that the cap will clear the smoke pipe of the locomotive and by-so doing the opening 9, will be thrown out of register with its flue D, and said flue is cut ofl from the external air. By this arrangement each flue D, it will be seen, contains a valve which is operated automatically, that is to say, the adjustment of the tube In, to and from the smoke pipe of the locomotive actuates the valve and the smokestack C, will not at any time have any of its flues D open below; for when any one of the valves is open its cap 0 will be over the smoke pipe of a locomotive. Therefore, any number of locomotives may enter and leave the house, and have their fires kindled by a draft in a common stack, without injuring the draft by communication below with the external air; each flue D' being open as its cap 0, is adjusted to the smoke-pipe of the locomotive below it, and closed previous to the leaving of the locomotive. The stack C, and its flues D, and tubes a, b, are constructed of metal.

Among the advantages of my improvement are the following: The raising of the funnel or sliding pipe automatically closes the opening in the branch pipe attached, whereby the heat emanating from the engines assists to warm or heat the enginehouse; this is an important feature, as all engine-houses of circular construction or large radius have raised domes or roofs, which are diflicult to heat and ventilate at the same time; it is obvious that a building with 15 or 20 tracks and as many outlets for the smoke can never be kept warmed or the engines kept from freezing in cold weather. l/Vith my arrangement there is virtually only one opening or outlet, that of the main stack; for the moment the sliding pipe is' raised, the opening in the branch pipe is closed. Locomotives vary in height. Engines of 6 feet diameter of driving wheels differ in height from engines of 4 feet diameter, consequently a variable or sliding pipe is needed. The top of the locomotive stacks also differs in diameter; the object ofthe flaring bonnet (c) is to secure a fit to the top of the locomotive engine-stack which it does regardless of the diameter; it also facili- I tates the raising of steam, and takes up the damp smoke and steam which would otherwise rust and injure the machinery.

I do not broadly claim the invention of telescope pipes for carrying off the gases arising from stoves, &c.; but

Having described my invention, I claim and desire to secure by Letters Patent,

The arrangement and combination With 10 the smoke pipes of locomotive engines of a sliding tube (6), flue D, and stack G, substantially as and for the purpose herein shown and described.

HENRY CLAYTON.
