SMOKE-CONSUMER.

Specification of Letters Patent.

Application filed March 3, 1908.

Patented July 21, 1908.

Serial No. 418,918.

To all whom it may concern:

Be it known that we, PETRUs A. 0. NY- GAARD, a subject of the King of Norway, and JOHN H. VVARREN, a citizen of the United States, residing at Jersey City and Newark, respectively, in the counties of Hudson and Essex, respectively, and State of New Jersey,

have invented certain new and useful Improvements in Smoke-Consumers; and We 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' figures of reference marked thereon, which form a part of this specification.

Our invention relates to an improved smoke-consumer which is particularly applicable to a locomotive, and the invention is designed to inject air from the atmosphere into the smoke-box of the engine, and direct this air current against or toward the end of the boiler so as to retard thev products of combustion while they are in the flues, sufficiently to cause their complete consumption so as to eliminate the emission of black smoke from the locomotive. This air current in the smoke-box is not directed into the stack and is not arranged to interfere in any way with the exhaust from the cylinders and its consequent action on the draft from the boiler, but is designed to have the nozzles or pipes injecting the air so disposed that they will not interfere with the current anywhere, except in the fiues of the boiler, as the delay in the flues will insure the consumption, by combustion, of the gases and the products of combustion from the fire-box. We prefer to make the inlet flues adjustable so that the amount of atmosphere to be admitted to the smoke-box and impinged against the fiues of the boiler can be regulated.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a section of the smoke-box and the end of a locomotive boiler provided with our improved attachment, and Fig. 2 is a half section and a half elevation of the front of the boiler.

Te illustrate a shell forming a smoke-box 10 which can be of any of the usual forms now employed in locomotive constructions,

and this smoke-box receives the gases and smoke and heat that comes out through the is usually used to direct the exhaust up the stack 12. This exhaust has a tendency to draw the products of combustion, consisting of smoke, gases, sparks and cinders, through the flues 16 shown in Fig. 2, these flues being in they boiler 11 as hereinbefore stated, and this draft with its rapidity and force of action increases the efficiency and quick steaming qualities of the engine by establishing this artificial draft, but it causes a great many unconsumed elements to be admitted from the SIl10l Si/&Cl in the way of black smoke,

sparks and cinders, the most objectionable of these being the heavy smoke, and it is to overcome the presence of this smoke that our invention has been devised.

We install a pipe or pipes 17, these pipes being preferably two in number and having their inlets on the outside of the smoke-box so as to take the atmosphere right into the pipes 17 and each pipe 17 is provided with a nozzle 18 which directs the air against or toward the boiler so that there is a suction on the pipes 17 toward the smoke-box, and in this way the current of smoke and gases through the tubes is arrested and at the same time mingled with air, and we have found by trial that the smoke is about entirely consumed and the efficiency and steaming qualities of the boiler are not afiected. We prefer to use dampers 19 on the outside or anywhere in the pipes 17, and in this way we regulate the amount of air admitted to the smoke-box and impinged against the end of the boiler and its flues.

We may use any number of pipes 17, but we prefer to use two as shown, and to dispose the nozzle or ends 18 so that they are equidistant between the center of the boiler and the sides thereof so as to give an approximately even distribution of air against the tubes. We prefer to bend the tubes so as to have them pass around the exhaust and the path ofthe exhaust jet so that there is no interference in any way with this part of the engine, and there is no attempt to inject the air into the exhaust, but the object is to avoid this exhaust as much as possible and direct the current without regard to it, but against the products of combustion that are issuing from the fines. This arrangement has been thoroughly tried and found to work satisfactorily in the elimination of the smoke nuisance, and the apparatus is also compact and cheap to install. It has a further advantage that it does not look cumbersome from the outside of the boiler, and does not interfere in any Way with the efficiency or steaming qualities thereof.

Having thus described our invention, what We claim is 1. In combination with a boiler and a smoke-box having a stack thereon, of a smoke-consuming device comprising a pipe or series of pipes passing through the walls of the smoke-box and having its inlet in the atmosphere, the outlet of the pipe being disposed between the stack and the boiler and arranged to ect a current of air against the flues of the boiler.

2. In combination With a boiler and a smoke-box having a stack thereon, of a smoke-consuming device comprising a pipe or series of pipes passing through the walls of the smoke-box and having its inlet in the atmosphere, the outlet of the pipe being disposed between the stack and the boiler and arranged to inject a current of air against the lines of the boiler, and means in the pipe for regulating the admission of air therethrough.

3. In combination with the boiler and a smoke-box having a stack thereon, and an exhaust directed into the stack, of a pipe or series of pipes passing through the Walls of the smoke-box and adapted to have its inlet in the atmosphere, and being disposed so that its outlet is adapted to direct a current of air away from the current of the exhaust steam passing into the stack and force the air against the end of the flues of the boiler adjacent to the smoke-box.

In testimony, that we claim the foregoing, we have hereunto set our hands this 2nd day of March 1908.
