Be it known that 1, WILLIAM F, Goes of Urbana, in the county of Gh'ampaign and State of llllinois, have invented a certain new and useful Improvement in Locomotit e-Engines, of which improvement the following IS a specification.

My invention, while particularly designed for application in locomotives operating in service at railroad terminals, which are generally of the type known as yard or switching engines, is equally and desirably applicable in locomotives used in general road service.-

The growth of cities and the increase of terminal traffic, and the substitution of elecltll tric propulsion therefor. which radical change, has, by reason of its high cost of installation and maintenance, thus far proved too expensive to be generally accepted as a means of removing the objections I draft appliance, adaptable to application,

without interference with existing accessories, in locomotive boilers of the present standard construction, in the operation of which appliance there shall be attained the substantial advantages of: (a) reducing by a more efi'ective utilization of the draft inducing capacity of the exhaust steam, the back pressure in the locomotive cylinders, and correspondingly increasing the efficiency of the propulsive action of the steam onthe pistons thereof; (b), reducing the amount of visible smoke emitted, by a more perfect contrbl of the draft action; (a), separating solid matter from the smoke, and reventing its discharge from the stack, whereby the percentage of dirt which is normally emitted is materially reduced; (at) economization of fuel by the utilization of solid material which, in ordinary operation, is wasted; (a), efl'ecting the entire suppression of the noise of the exhaust; (f), insuring more eflective blower action, when the locomotive is stand-- ing or drifting, and suppressin the noise of the ordinary blower, and; (g providin for the ready and expeditious removal an replacement of the apparatus, as may, from time to time, become necessary or desirable for renewal or repair of its own members or of other accessories of the locomotive boiler. The improvement claimed is hereinafter fully set forth. p y

Referring descriptively to the specific embodiment of my invention which is herein exemplified, it is illustrated as applied in a locomotive boiler of the present standard I type, in which the shell or waist, 1, is traversed by a plurality of firetubes, 2, which extend from a firebox at the rear, which is not shown, to a, smoke box, 4., connected, in

the usual manner, to the shell, 1, of the boiler. The forward end of the smoke box is closed by a front, 4, haying a door, 4, closing an opening in the front throu h which access is afforded to the interior of the smoke box, for the insertion and removal of members contained therein, and in the forward portion of the shell, is a superheater header, 5, superheater pipes, 5, steam pipe, 6, etc. The smoke box is supported on cylinder saddles, 7, in the usual manner, and. is provided at top, with the usual passa e, open to the stack, 8, through which t e waste gases of combustion are discharged to the atmosphere.

In the practice of m boiler of the type.

roo

above described, the ordinary vertical exhaust pipe, and exhaust tip or nozzle, are substituted by a turbine casing, and a connected turbo-muflier, the construction :of which, and their relation to the locomotive cylinders and boiler will now be described. The turbine casing, 9, is an annular casting, located substantially concentric wlth the cylindrical wall of the smoke box, the rear end of which casting is flanged,'and -1S connected by bolts to the flanged front of a hollow turbo-muffler, 10, which is preferably made in two sections, bolted together in its horizontal axial plane, and 1s 1n the form of a frustum of a cone, havlng its smaller end, which is at its rear, slightly beveled or flared outwardly, as most clearly shown in Fig. 3.- Lateral longitudinal downwardly projecting legs, 10, are formed on the turbo-muffler, and are connected, detachably, as by bolts and nuts, to vertlcal standards, 10 ,,extending longitudinally in r the smoke box and secured to the cylinder saddles, 7. The smoke box door opening is made of sufficiently large diameter to enable the turbine casing and connected turbo-mufsired.

fier to be passed through it, for insertion in, and removal from, operative position as de- An exhaust supply passage, 9, which is open at its lower end, is bolted to the front of the turbine casing, 9, the lower end of said passage being connected to a short curved exhaust connection elbow, 7, which communicates, in the manner of an ordinary conformity with the end of the turbo-muffler, as shown in Figs. 3 and 5.

An operating shaft, 12, is journaled in bearings, 10, 10, in the turbo-muffler, 10, and a steam turbine, 13, which may be of any suitable known and preferred construction, is fixed on the forward end ofsaid shaft. A draft fan, 14, is fixed on the rear end of the operating shaft, and a thrust bearing, 10 is supported on the turbo-muffler, between the journal bearings, 10, 10.

The journal and thrust bearings are inclosed in a recess formed in a central supporting standard, 10, cast integral with or secured to, the turbo-muffler, and covered 'by a cap 10, an oil receptacle being thereby formed, to which lubricating material may be supplied through a pipe, 19, leading from a source of supply exterior to the boiler. A suitable drainage port, 10 (one or more) is formed at the larger end of the turbo-mufiler.

Exhaust steam is supplied to the buckets of the turbine, 13, when the locomotive is running with open throttle, from the connection elbow, 7*, and supply'passage, 9, through a plurality of ports, 13, formed in the rear wall of the passage, 9*, and disposed in a circle concentric with the operating shaft. For the purpose of operating the turbine when it isdesired to increase the draft in periods in which the locomotive is standing or dripping, a valve controlled blower pipe, 15, is led from the steam space of the boiler into the turbine casing, 9, said pipe being open to the buckets of the turbine throughsupplemental ports, 13, in the rear wall of the passage, 9".

The portions of the smoke box, 4, in front and in rear, respectively, of the draft fan, 14:, are separated by a partition or fan housing, 16, which closely surrounds the rear end of the draft fan, and is open centrally thereto. The fan housing is forwardly curved or inclined, and at its forward end, is inwardly recurved, as shown in Fig. 1, its inwardly curved portion form- 1 ing a baflle and constituting the wall of an annular peripheral chamber, 16, into which dust or solid matter, discharged from the boiler tubes, is driven by the centrifugal force generated by the revolutions of the draft fan. As will be readily understood, the space .within the smoke of the fan housing, 16, will, when the 1000- motive is in operation, alwa s be subject to pressure greater than that of the atmosphere and the, space in rear of said housing, to pressure less than that of the atmosphere, the difference in pressure being due to the action of the draft fan. A delivery nozzle, 16", projects from the lower portion of the chamber, 16, through the shell of the smoke box, and a delivery pipe, 17, leads from said nozzle to any preferred receptacle, which may be the firebox of the boiler, the ash pan, or a 'box; or casing from which the delivered solid matter may be withdrawn from time to time as may be required.

The space between the chamber, 16, and the turbo blower, which is open to that forward of it in the smoke box, may, if rendered desirable by exceptional conditions, or required by legal enactment, be closed by a sheet of netting or perforated plate,

' 18, as indicated in Fig. 8.

In the operation. of the appliance, when the locomotive is running under steam, i. e. with its throttle open, all the exhaust steam from the cylinders is delivered to the turbine, 13, which, with the connected draft fan, 14, is thereby rotated. The centrifugal actlon of the wings of the fan, upon the ox, in fronterner/a products of combustion passing out of the tubes of the boiler, draws the gaseous and sol-id matters of the products to and through the central opening of the partition, 16, and into the circumferential chamber, 16, thereof. The gaseous constituents are forced by the fan through the annular space between the wall of the chamber and lltll tion drop to the bottom of the chamber, 16,

the turbo-mufiier, into the smoke box space which is forward of the housing, from which they are continuously discharged to the atmosphere. The dust and solid matter contained in the products of combusfrom whichthey are also continuously discharged through the nozzle, 16", and delivery pipe,-17. The exhaust steam from the turbine fills the space within the turbomuffler, 10, and'thence esca es, in a quiet continuous outflow stream t rough the annular discharge. assage between the turbopipe, 15.

mumer and the flange, of the'end plate, 10, to the smoke box, and therefrom to the atmosphere, through the stack. lit the condition of the fire should be such as torequire artificial draft when there is no exhaust from the locomotive, which is the case when standing or drifting, the turbine and draft fan are started, at greater or less speed as required, by the admission of boiler steam to the turbinethrough the blower Among the operative advantages, the following may be noted. The exhausting action of the draft fan upon the products ofcombustion, causes the actual value'of the negative and positive pressures in the smoke box, as measured from atmospheric pressure, to be less than in ordinary"practice. Thus, the reduction of pressure in the space in rear of the fan housing need be only sufficient to draw theproducts of combustion through the boiler tubes and the central opening of the fan housing, and the excess of pressure in the space forward of .in creating draft than the'exhaust pipe and,

tip common in present practice, and fromv this fact there results a reduction of back pressure in the locomotive cylinders and a corresponding econom v as compared with the present practice. nothermaterial feature of advantage is found in the complete elimination of the harsh noise of the ordinary exhaust and of the-ordinary blower,

and the minimization of liability to the discharge of smoke, and especially of solid matter, to the atmosphere, with the capacity of the utilization of, the unconsumed particles of fuel by their return to the fire-box. Again, the operating shaft and its bearings being, when operatmg, inclosed in exhaust steam, they are protected from deterioration by the action of the high temperature of the front andgases. The capacity of ready removaland replacement of the turbo-muiiier and .its attachments is also a feature of much practical value, as upon detaching the connections with the exhaust connectionand supports,-which can be readilyand quickly done, the'turbo-mu'liier and related arts can be slid, upon the supports, out of t e smoke box, thus adording ready access to the superheater and front tube sheet whenever required.
