COMBINATION TURBINE AND MUFFLER.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed March 9, 1906. Serial No. 305,039,

To all whom, it may concern.-

Be it known that I, GEORGE E. FULTON, a citizen of the United States, residing at J ersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Combination Turbine-Motors and Mufflers, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

My invention relates to pressure-fluid engines, and particularly to an improvement in mufflers, which forma part thereof and which are applied to the exhaustpipe of such pressure-fluid engines; and the object of my'invention is to utilize a certain percentage of heat units contained in the exhaust-gases for motive purposes, a further object being to provide in combination herewith an efficient muffler for the exhaust-gases of a pressurefiuid engine to which my invention is applied; and with these and other objects in view the invention consists in a combined turbinemotor and mufiier of the class specified, constructed as hereinafterdescribed and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which- Figure 1 is a cross-section of my improved apparatus on the line 1 1 of Fig. 2 looking in t e direction of the arrow as. Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Fig. 3 represents a cross-section on the line 1 1 of Fig. 2 looking in the direction of the arrow y; Fig. 4, a partial section on the line 4 4 of Fig. 3, and Fig. 5 is a side view of a four-cylinder pressure-fluid engine with my combined turbine-motor and muffler attached to the exhaust-pipe of the same.

In my improved muffler I unite the muffling features with a turbine set in motion by the combined action of steam and gas under pressure. The steam as a motive power is generated within the muffler, one portion of which serves as a flash-boiler supplied with water from a tank or pump under pressure. The heat necessary to operate the flashboiler is derived from a part of the exhaustgases which pass through the muffler, and the steam thus generated is made to impinge against the blades of the Well-known device, a turbine-motor. This motor, running in bearings, forms a part of the mufiiing apparatus, and the turbine itself is alsoplaced within said muffler. Another part of the heat of the escaping exhaust from the main pressure-fluid engine is made use of to expand to a lower stage within the inufller and is then admitted to the blades of the turbine-motor to assist the. steam heretofore mentioned and generated within the muffler to rotate the turbine-wheel by also impinging against the blades of the same. After this combined motive power, which heretofore has been wasted by exhausting directly into the outer air, has given up a certain percentage of its heat units transferred into motive power, the same is exhausted under nearly atmospheric pressure into the outer air.

As illustrated in Fig. 5 of the drawings. my combined motor and muffler a is attached to the exhaust-pipe b of the four-cylinder pressure-fluid engine 0. The power generated within my apparatus, as shown in the drawings, is transmitted by means of a belt d and the pulley (1, attached to the shaft d of the turbine-motor, to the pulley 61, attached to a shaft (1 for the purposeof running a fan, which may be used in this instance for the purpose of air-cooling the jackets of the main 0 linders of the engine 0. It is obvious that t e power thus generated by means of my apparatus may, by means of proper transmission, be made use of to assist the main engines driving the main shaft of the same for running the dynamo of the electric sparking device, &c.

The apparatus proper consists of the following features, which consist of an outer circular side plate e, provided with a boss e,

which is provided with an internal screw-' thread, to which can be attached the exhaustpipe b of the main pressure-fluid engine. Another circular side plate e corresponding in size, shape, and dimensions to the former side plate e, is also provided with an internal thread ed boss e to which an atmospheric escape-pipe can be attached. These two circular side plates e and e are bolted to an annular casing-ring, which is composed of two integral parts f and f the outer ring f having inwardly-extending corrugations j, while the inner ring f has outwardly-extending corrugations f These rings are placed concentrically with each other, leaving at their corrugated joint an air-space j, which extends circumferential, as well as transversely.

A number of circular partition-plates g, h, i, k, and l and circular washers m, n, and 0,

all conforming in diameter with the outer casing-ring f and the side plates 0 and e and having a corrugated open space correspond.- ing to the air-space f above mentioned, are joined together with the above-named side plates e and e and the casing-ringsf and f by means of the bolts p, which pass transversely through these plates an 1 rings," as illustrated in Fig. 2 of the crawings, and when arranged in the manner inzicatei in said figure they form a closed. circular mufiling device, with two large compartments g and 1' and three small compartments s,s, and's The outer side plate e is also provided with an outwardly-extending boss 0*, to which is attached a pipe, which is adapted to be connected with a tank or pump bringing water under pressure, if so desired, into the interior of the narrow air-spaces s withinthe.

mufliing device, which air-spaces, as illustrated in the drawings, are contiguous to and interconnected with each other.

Placed within the larger chamber g is a worm of copper tubes q of one or a number of series of convolutions. I One terminal of this worm connects at g with the steamchamber 8, which latter is formed by the cir cular partition-plates t and 7c and the intervening washer n, while the other terminal 'of said worm g" connects with the same steamchamber 3' at 9 By this means the interior of the copper worm g, .the chamber 8, the circumferential corrugated space f, the chambers s and 0 respectively, formed by the outer end plates e and'e and the partition-plates g and Z, and

washers m and 0 form one closed chamber,

which is the flash-boiler proper, to which water can be admitted by means of the pipe e and from which steam can be generated within the same, and said steam finds its exit by means of two steam-ports u and. 11., located in'the partition-plate k. The tubes q are expand therein, give up a part of their heat to the adjoining partition-walls g and 'i, and

' thereby perform the functions of this part of the flash-boiler. A series of outlet-ports v, as shown in Fig. 3, are located in the partition-wall 'i, said outlet-ports '0 being placed, as are also the steam ports u and a, radially to the axis of the apparatus and connected with the larger hot-air chamber q, as shown in Fig. '4, and an individual washer 1), pro vided with a corresponding opening, being placedwithin the steam-chamber s in order to cut off the communication therewith and to permit of the exit of the gases from the 'the copper tubes q and will then exhaust into the outer air under nearly atmospheric pressure, thereby serving the combined purposes of a sound-muffler to the main pressure-fluid engine to which my apparatus has been. at tached, as well as generating steam for secondary motive purposes and also serving direct as a motive power.

The turbine-motor shaft 10 is mounted in ball-bearings W, as shown in Fig. 2 of the drawings; butthese bearings may be of the usual form of plain bearings, and they are bolted to the end. plates e and e and form, with the shaft w, the axis of the motor or muffling device. A turbine-wheel w, having the usual radial blades w is placed between the two concentric band-supports w and co the latter being supported by the central web member w, which in turn is attached to the shaft w by means of lock-nuts, setscrews, or keys.

The blades to of the turbine-motor receive the impact ofthe steam issuing from the steam-ports u and '11., as well as from the gasports 1), which will cause'the same to be rotated in the manner of impact-engines.

I00 It will thus be seen that by means of my' combined motor and mufliing device motive power is generated from the exhaust of any ressure-fluid engine to which the same may e attached and that my device also acts as I a mufller by reducing the exhaust pressure fluid to a lower stage before expanding the same into the outer air.
