LOCOMOTIV-E DRAFT APPLIANCE.

Application filed June 23, 1920. Seria1.No. 391,019

T 0 all whom it may concem:

Be it known that I, ANTON K. KUsE- BAUCH, a citizen of the United States, residingat Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improve ments in Locomotive Draft Appliances, of which the following is a specification.

This invention relates to locomotive draft appliances, particularly of the turbine exhauster type and it has for one, of its pri-' mary objects the provision of improved means in an appliance of this character for efficiently collecting the cinders and preventing the ejection of sparks which cause fire losses along the roadway. In this connect.-

- tion through Fig. 1.

tion'I contemplate segregation of the cinders' so that all of them above a certain size are guided to a point where they can be removed with a minimum of interference from the flow of the discharged gases. j

The foregoing, together with such other objects as may hereinafter appear, I obtain by means of a construction which I have illustrated in preferred form in the accom.

,panying drawings, wherein:

Figil is a front elevation of a locomotive smoke box equipped with my improvements, the end or cover plate being removed; and Fig. 2 is a central vertical longitudinal sec- Referring now to the the steam turbine A, for the operation of which exhaust steam is ledfrom the valve chests through a pipe 6, casting 6 and a Y- shaped member 6 the exhaust steam being delivered from the latter into the turbine and then discharged from the turbine in the manner indicated by the arrows a; the fan B driven from the turbine; and the gas discharging and spark arresting mechanism asdrawings, my invention'is exemplified as applied in aloco motive boiler of the present standard type,

sociated with the fan and generally indicated by the reference letter C. To the rear of the turbine is a member 7,

the forward part of which constitutes a housing for the fan B, while the rear part thereof forms a chamber into which the gases from the fan are discharged and from which they flow t0 the stack- D through a discharge passagefi, The forward part or housing is sufiiciently large to provide an annular cinder collecting space or chamber 1), as will further appear. The member 7- is arranged adjacent to a vertical partition 7 transversely disposed in the rear part of the smoke box. This partition 7* together With the rearwardly extending apron 7 at its lower portion serves to divide the smoke box into-two chambers, a forward chamber F and a rear chamber G, and the products of combustion are exhausted by withdrawmg them from the rear'chamber by means of the apparatus generally located in the forward chamber through the opening 7 in the partition as will more clearly appear below. A cone-shaped member 10extends from the rear Wall of the member 7 and from the opening 7 to a point adjacent the fan and located within such member is a cone-shaped screen 11 of sharper pitch, the

front end of which is connected with a coneshaped member 12 preferably imperforate.

The fan B is provided with an annular rib 13 which is in substantial alignment with the end of the cone-shaped member 12, both of the members conforming to the general .curvature of the fanparts.

The shape of the rear portion of the member 7 is such that with the cone 10 in place, a sort of V0- lute passage E is provided for the gases, discharged tangentially from the fan,'such passageterminating in'the discharge assage 9,

as Will be seen from inspection of ig. 1.

The operation of the mechanism is as follows: The gases, together with such cinders and sparks as are in suspension therein, are

sucked into the cone-shaped screen 11 through the opening 7 by the action of the fan and the bulk of the gases, together with the smaller cinders are drawn through the screen into the space 0 formed be ween the.

are d1scones 10 and 11 and cone 12, an charged tangentially from the periphery of the fan. The gases in leaving the fan take the course indicated by the arrows marked 2 and flow through the passage E and are discharged to the stack D through the passage cinders and sparks will be deflected and segregated by the screen 11 towards the center of the fan and will be carried out through the channeled formed by the fan and the cone 12 and the annular rib 13 and will be discharged from the periphery of the fan and will be deflected by the sloping Walls of the housing into the collecting space 72 in the same general manner as the lighter particles which are drawn through the screen 11,

I have found that the foregoing arrangement enables me to collect almost all of the cinders and it is practically impossible for any spark of a size sullicient to cause a fire to find its way out. By so screening and guiding the coarser cinders toward the center 3 of the rear of the fan and then discharging them at the forwardperiphery of the fan well at a point farther advanced into the deflector housing they are less affected by the flow of the discharging gases and, therefore, have a, less chance to escape. The larger cinders are generally the ones which cause the most trouble by fires if thrown out of the stack and by this arrangement I am enabled to catch practically all of them.

By providing the screen with an outlet and taking care of the discharge therefrom as described I am enabled to avoid clogging thereof which, obviously, is a marked ad vantage.

I claim:

1. In a locomotive draft-appliance, the

, combination of a fan, a housing about the fan, an inlet member leading to the fan, and a foraminous member 1n said first member discharging into the fan part1cles too large to pass through it, and'arranged to provide a space therebetween.

2. In a locomotive draft appliance, the combination ofa fan,.a housing about the fan, a cone-shaped inlet member leading to the fan, and a foraminous cone-shaped inlet member in said first member, arranged to provide a space therebet-ween.

3; In a locomotive draft appliance, the combination of a fan, a housing about the fan, an inlet member leading to the fan, and a foraminous inlet" member in said first mem'ber arranged to provide a space there between, said fan being constructed to provide discharge passageways respectively in substantial continuation of the passage between said two. m embers and, of the interior of the foraminous member.

fan, an inlet member leading to the fan, and

a' foraminous inlet member in said first member arranged to provide a space therebetween and discharging into the fan particles too large to pass through it, said housing having a sloping wall and a collecting chamber for cinders adjacent thereto.

6. In a locomotive draft appliance, the combination of a fan, a housingabout the fan,- an inlet member leading'to the fan, and a foraminous inlet member in said first member arranged to provide a space therebetween and discharging into the fan, said fan being constructed to provide discharge passageways respectively insubstantial continuation of the passage between said two members and of the interior of the foraminous member, and the wall of the housing substantially opposite said passageways being sloped.

7; In a locomotive draft appliance, the combination of a fan, a chamber adjacent to fan and forming a housing therefor and a cinder collecting space, an open ended inlet member in said chamber leading to the fan, and a second, foraminous, inlet member insaid first member discharging into the fan, the cinder collecting space being adjacent the point of discharge from the fan.

-8, In atlocomotive draft apparatus, the

I 11. In a locomotive draft appliance, the combination in the smoke box with the stack and the flue sg of a partition between the stack and the flues, an exhaust fan'on the stack side of the partition, a housing around the fan having a discharge .to the stack and a spark and cinder collecting spacearound periphery of the fan, an opening in the ther toward the center of the fan than the point where the member dischargesvwhereby the matter not passed by the screen is discharged bythe fan nearer the forward periphery thereof than is the matter passed.

12. The combination witha locomotive draft appliance comprising an exhaust fan through 'which the products of combustion areidrawn, a collecting chamber for cinders at one side of the discharge from said fan,

and means for deflecting cinders vissuing from the collecting chamber side of the fan discharge laterally to said chamber; of
