Letters Patent No. 81,602, dated September 1, 1868.

` IMPROVEMENT INLOGOMOTIVE-SPAR ARRESTERS.

TO ALI; WHOM IT MAYlCONCERN: t

Be itknown that I, IRA Cuos'rltfof Exeter, in the county of Rockingham, and State of New Hampshire, have invented a new and useful Improvement and Attachment for Locomotive-Engines and Railroad-Trains; and I do hereby declare thatvthe following is va full and exact description of the same, reference being had to the accompanying drawings, and letters of reference marked thereon,

Figure 1 is a side elevation of a locomotive-engine, tender, and car, showing the improvement.

Figure 2 is au end elevation of a car, showing the means employed to operate the coupling, C B.

Figure 3 is an enlarged view of the coupling C B, showing the mode off constructing the same.

Figure 4 is an eind view, of 'the coupling C.

' Figure 5 is a plan of that part of the improvement which is attached to the smoke-stack E, showing the movable cover Dv and the airlapertures, a a a a a a. v

Figure 6 is a sectional view of the same', showing the mode of attaching the ,movable cover D.

The nature of my invention consists in devices hereinafter mentioned for conveying the smoke, steam, and sparks from the smoke-stacks of locomotive-engines to the rear of the trains through the tube A, as shown in iig. 1.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. A i l The tube A is constructed of thin sheet met-al, or any other suitable material, in sections or lengths suited .to the length of the locomotive, tender, or car to which it is to be attached, and itis joined together by means of the coupling C B, tbatlpart of which, marked C, is composed ofsome elastic sheet metal, and is constructed in staves, riveted together at one end, as shown atf, fig. 3.l That part of the coupling marked B, is composed o'f-India rubber, or any other elastic and iiexible material. Both are united, andare attached to and become ,a part ofthe tube A, and form a flexible coupling or connection between the engine and tender, or between the c'nrs, such as will admit of the extension and contraction, and of the various oscillating movements to which the train is liable while in motion.

l In order to facilitate making up the train, or coupling kthe engine, tender, and cars together, I construct the coupling in stoves, as shown in the enlarged viewg. 3. The 'end of said coupling can be contracted in fsizez so as to readily enter the tube of the approaching car, by pressing down on the cord or band d, which Adranghtwhilo the engine is in motion.

rencircles the end of -the coupling C, land passes throughthc holes in the guides c c, and terminates in a loop or stirrup, at g. By releasing thepressux-e on the loop or stirrup g,'tho coupling at once expands to its original size. s

That part of the tube A which is attached to the smoke-stack E, is provided with a cover, D, which may be removed,l so that the draught nay be maintained in the ordinary` manner while the engine` is at restn- It is also provided with air-apertures, as shown at a a a` a a a, figs'. 1, 5, and 6, for the purpose of facilitating the When thc'train is in motion, all the smoke, steam, and sparks are conveyed from the smoke-stack E, through 'the tubo A, to-the rear of the train, thereby securing the passengers, as well as the op'eratives from the annoyance always 'experienced whiltravelling on railway-trains.

W hat I claim as my invention, and desire to secure b LettersPatent, is- 1. 'lhe construction and arrangement of thotube A, ysmoke-stack E, cover D, and air-apertures a a aa a a,

substantiallyvas/ shown and described.

2. The coupling C B, cord orbandd, and guides c @substantially as shown and described. 3. The coupling G B, coustructedas described. 4, The arrangement of the cordd and guides c e, substantially as described. l
