IMPROVEMENT IN SMOKE AND SPARK CONVEVERS.

Specification forming part of Letters Patent No. LSLGSS), dated May 19, 1574; application filed Mey 12, 1874.

To all whom it may concern: t

Be it known that I, TnoMAs Dn tlonnzo, of the city, county, and State' of New York, have invented a new and useful Improvement in Smoke and Spark Conveyers for Locomotives; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings making part of this specification, in which- Figure lis a side elevation, partly in section. Fig. 2 is a vertical longitudinal section, and Fig. 8 is a vertical transverse section through the escape steam-pipe.

The same letters are employed in all the fi gures in the indication of identical parts.

This invention relates to tubular conveyors extending from the uptake of the locomotive back over the train, for the purpose of carrying the smoke and sparks and discharging them behind the tra-in, so as to relieve the passengers from this most disagreeable annoyance, which has become so otfensive since the general introduction into use of soft coal in the generation of steam in locomotives.

The tubular conveyer is made in sections permanently attached to the dilferent components of the train, which are connected as the train is made up by means of couliiling-pipes.

My improvements consist in the use of, first, coupling-pi pes connected with sliding tubes on the fixed tubes by means of a ball-and-socket joint, which will permit the necessary play of the pipes with the motion of the cars 5 second, a swinging valve having a hole to coliform to the escape-pipes for smoke and steam, and used in combination with another valve, which covers said hole when the former valve is raised to close an opening in the top of the conveyertube; third, a curved uptake extending from the shell of the boiler into the open-mouthed conductor with auniform and continuous curve, so as to oppose a minimum of resistance to the draft fourth, a Water-recess inthe conductortube for catching the sparks.

In the annexed drawings, A is an open fuir nel-mouthed tube on the locomotive, extending forward of the uptake and back over the cab. B is the uptake, which, instead of being vertical at the bottom and curved so as to be horizontal at the upper end, as heretofore used, or inclined to the rear, as has been proposed, I

make of a uniform curve from the point where it emerges from the Hue-chamber of the locomotive to its termination in t-he conveycntnbe. The object of this is to reduce to a minimum the resistance incident to a danger in the d1- rection of the draft from vertical to horizontal. U is a hinged valve used to close the tubular conductor, except where the draft passes through a hole in the valve, corresponding to the opening at the upper end of the uptake. Vhen this valve is raised it closes a hole of the size of the valve in the upper side of the tube A immediately over the mouth of the uptake. When the valve C is raised another hinged valve, D, is dropped, so as to cover the hole in the valve C. When the latter is dropped the valve D is raised, so as to completely open the escape-hole in the tube A. This is done by means of the arms E and Ef, respectively attached to the valves C and D, and connected by the rod E2. A rod, E3, extends from the cab to the arm E, so that the engineer can conveniently operate the valves. F is the escape pipe from the steam-dome. It may be straight, as shown in Figs. l and 3, with valves to permit the escape of the steam either .into or above the tube A 5 or this pipe may be curved like the uptake, and fitted with valves Gr and H, operated by rods I, I1, l2, and I3, in all re spects like those of the uptake-valves. K is a sliding or telescopic joint on the tube A, having a spiral spring, L, pushing it outward. The mouth of this joint is formed as a socket to receive the spherical end of the couplingpipe M, forming a ball-andsocket joint, which will permit the cars to play laterally or vertically without breaking the continuity ofthe conveyer. spring-arm, M', which sustains its weight and holds it in such position that the joint will be formed by merely coupling the cars. Another telescopic section, N, is similarly attached to the forward end of the section A', carried on the tender. Similar pipes and couplings are extended across the entire train. It is manifest that the joint eanfbe formed with only one telescopic joint in connection with each coupling section, but I prefer to use them on each end of each of the xed sections of the pipe, as shown.

In order to make a receiver to catch and eX- This joint is supported upon a tin guish the sparks, which often do much damage by kindling fires on the side of the track, I propose to bend the tube over the tender, as shown in section in Fic'. l, rIhe sparks striking the curved tube Will be dciiectcd and thrown down and caught in a bed of Water carried in thc bottom of the bend, as shown at I). They may be taken out from time to time by opening the pipe P and drawing oit' the Water. Fresh Water maybe introduced by a funnel, Q, closed by a lid when not in use.

I do not intend to claim, broadly, the use of a Water-chamber for catching sparks in the uptake of alocoinotive, for they are Well known, and the principle has been applied in many different devices. My invention is limited to the particular mode of forming a water-chamber in a downward bend of a continuous horizontal pipe, which forms an extension of the uptake.

In operation, when the train is going forward, the Valve O-Will be raised to open the funnel-mouthcd pipe A, so that a current of air will be established `through the latter, materially assisting the draft. Then the train is stationary or going backward the Valve C should be dropped, closing the tube A and permitting the draft to escape vertically from the mouth of the uptake.

.Wfhat I claim as my invention, and desire to secure by Letters Patent, is-

1. In combination with the sectional con- Veyer-tube and telescopic joint and spring L, a connection-pipe, M, forming with the sliding joint a ball-and-sockct joint, substantially as set forth. A

2. In combination with the conveyertube A and uptake B, having a horizontal discharge, the valves C and I), arranged to operate in relation to one another, for adjusting the draft, substantially as set forth.

3. In combination with the conyeyentube A, having an open mouth, the uptake B, forming a continuous curve from its point of einer gence from the flue-chamber to its mouth in thc conveyer, substantially as shown.

4. The Water-recess I?, formed in the con- Veyer-tube by curving the same, substantially as set forth.

In testimony whereof I have signed my naine to this specification in the presence of two subscribing witnesses.
