LOCOMOTIVE SPECIFICATION formingpart of Reissned Letters Patent No. 11,437, dated September 4, 1894.

Original No. 471,281, dated March 22, 1892. Application for reissue filed March 21, 1894. SerialNo. 504,567.

To all whom it may concern: I

Be it known that I, BENJAMIN. F.;TAYLOR, a citizen of the United States, residing at Newark, in the county of Essex and State .of New Jersey, have invented certain new and useful Improvements in Locomotives; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as-will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. 1

The object of this invention is to .relieve the piston as much as possible from atmospheric pressure and to destroythe smoke, gases, and cinders by the introduction of air intothe exhaust pipe and smoke stack, impelled by the speed of the locomotive.

The invention consists in the arrangements and combinations of certain devices to so-. cure these results, as herein set forth, "and finally pointed in the claims.

Referring to the accompanying drawings, in which similar letters of reference indicate corresponding parts wherever they occur, Figure 1 represents a central longitudinal section of a locomotive boiler, Smokestack, exhaust pipe, cylinder, .&c., and Fig. 2 is a front end elevation of the boiler alone.

In said drawings, a indicates the boiler, b the smoke stack, 0 the cylinder, and. d the exhaust pipe.

In carrying out my invention I tap the exhaust pipe, preferably in front at d, below the smoke box, if it can be done at that point, and if not, at the most favorable point al lowable to utilize the benefit of the current of air produced by the speed of the engine, and attach an outlet pipe 6 to the exhaust pipein the rear or opposite the inlet d. If the mouth or end of said out-let be obstructed by any portion of the locomotive, I attach an elbowf thereto and carry it downward or to one side by means of a union coupling, forming a swivel coupler g, so as to afford a free and unobstructed passage and escape for the air and steam, as'indicated in Fig. 1.

as possible.

DIVISION. A.

At the bottom of said elbow, if" desirable, I form" another elbow h with an opening o at the joint to further admit a'current of air thereat. At the inner portion of said inletpipe and the outer extremity or portion of said elbow I also form a series of-fnnnel shaped openings, 7;, the'design. of which is to mingle with and draw the exhaust steam from the exhaust pipe, and to thereby decrease the atmospheric pressure upon the piston as much as possible. eating the movement of the air in the pipes and funnel shaped openings. As a further means of aiding to secure these results I tap theexhaust pipes at different points above that above described, either below the smoke box, as indicated at j, Fig. 1, if it be admissible, or if not above the lower line of the boiler, or both, as indicated by the inlet pipe or pipes (as there may be several) k, which pass through the front end of the smoke box to said exhaust pipe, or to a chamber formed around the top of the same, as shown in Figs. 1 and 2. The inner ends of said inlet pipes may be curved upward if desired within such exhaust pipe or chamber, the object be- Arrows are shown indi carry the exhaust steam, if there'be any, out

through the smoke stack, and also to condense-the steam and to mingle the air with the gases and smoke, to destroy them as far These pipes may enter from the side or top of the smoke box, as indicated at.

k, if there be no room in the front end.

An air chamber m is shown formed around the exhaust pipe in Fig. 1, and connected with the inlet is which is formed with funnel shaped openings. Two pipes or elbows Z, Z, connect the interior of the chamber m with the inside of the exhaust pipe, the elbowl leading the air from the chamber into the pipe,while the elbow Z leads the steam from the pipe into the air chamber; the mingling of the air with the steam resulting in both cases. An elbow pipe 41. is connected with pipe 7e and with the exhaust pipe, and formed with an opening eat the. bottom to admit smoke and gases from the smoke box, which 7 are thus mingled withthe air and steam, and

are expelled through the smoke stack. The chamber m-extends a little above the top of the exhaust pipe-d, and 'beingann'ular'i'n form projects an annular current of air'upward around, the inouth'of such pipe,-th us assist; ing the discharge ofthe steam without penetratin g the i-nterior of the pipe. Theair chamher thus promotes the dischargeiand condensation of the steamwithout obstructing the interior of ;the pipe'd, as in-the case'of the elbow l, and upon the inlets j and k. As a tom and top, at p and p, the latter connecting with an air chamber q, which is'formed around the upper end of the stack, as shown in Fig. 1. The inlet at p is-provided with a curved pipe or elbow projected inwardly and upwardly from the side of the stack, and such inlet pipe is provided upon its side with an opeuingor passage 0. Such opening,'like the opening 0', in the pipes 'nand h, is-provided' upon its outer side with a lip 0' to direct a portion of the rising steam and smoke into such opening to mingle it withthe current of air inside suclipipe. An arrow is shown entering the. opening 0 to indicate such move-' ment toward the interior of the pipe.

The chamber q is shown'of annular form extending'around the entire top of the stack and ,is provided with/a, cover q'which is projected' inwardly toward the top'of the stack, and difiuse's the air throughout the chamber before it is,discl1arged around the "top of the stack, The cover also directs the air inwardly around the top of t-he stack, as indicated by the arrow qitthus mingling'such-air current intimately with the rising smokeand steam. The eflect of the iu'rushing air at these several points when-a locomotive is rushing at 'full. speed, in securing the results'mentioned will be obvious. These inlets or any of them may; be provided with automatic valves 11',

which in this case are plain or flat disks suspended at the entrance by a pivotal connection 3 and swing inward automatically when the locomotive is in motion, and when at rest and ingetting up steam these valves will be closed automatically, so as not to deleteriously. afifect the'draft, as will be understood,

The location-and construction of these severa-1 devices may be varied to suit the (litter- ;ent stylesof locomotives, as will beu'nder;
