CAR-VENTILATING SYSTEM.

Application filed September 2, 1919.

To (17/ whom it may con-061m. I

Be it known that I, PETER B. Bocanr, a citizen of the United States, residing at Milwaukee, county of Milwaukee, and State of IVisconsin, have invented new and useful Improvements in Car-Ventilating Systems, of which the following is a specification.

Iy invention relates to improvements in car ventilators.

The objects of my invention are to provide practical and eflicient means for utilizing the motion of the car to not only deflect air into the interior, but to prevent the entry of cindersyand to a large extent to exclude smoke; to provide tempering and distributing the air through the coach and exhausting the foul air; ,and to accomplish the above objects while preserving all useful interior space, avoidinga detrimental charexterior projections of preserving the neat acter and substantially and attractive standard designs of railway 'cars in all respects while securing adequate ventilation and complete change of air within the car every few minutes while the car is in motion and at longer periods when at rest.

In the drawings:

Figure 1 is a view, in horizontal section on line 11 of Fig. 2, showing a fragment of one end portion of the cupola or raised centralportion of the roof of a railway car, equipped with my improved ventilating apparatus.

Fig; 2 is a vertical sectional view on line 22 of Fig. 1. f I

Fig. 3 is a sectional View on line 33 of Fig. 2.

.in the inner wall Like parts are identified by the same reference characters throughout the several views.

The railway car of which a fragment is shown in the drawings is of ordinary type except as to the ventilating apparatus herein described.

A set of air receiving chambers 1 isprovided, each chamber preferably having the form of an elongated rectangular open endedbox fitted with screens 2 at the respective ends, supplemented by additional s'creens of ne mesh woven wire 3, each within the chamber at a short distance from the associated end screen 2, and preferably obliquely placed to direct cinders and other solid materials toward the inner wall 4. These chambers 1. each have an opening 6, 4, conforming generally to the size of the deck sash opening in cupola Specification of Letters Patent.

wall of the car to which the chamber is fitted, and at the margins of this opening 6, the chamber is secured to the walls of a pas sage 7 WlllCll extends through the deck sash opening (the sash being removed) and de-- livers air from thereceiving chamber to a heating chamber 10, provided with suitable radiators preferably comprising a set of steam coils 11, about which the air passes to an opening 12 and thence to the occupied portion of the car.

he air receivingchambers 1 are provided with partition walls 13 and 14 which extend from the outer wall of the chamber along converging curved lines into the passage 7. The latter is preferably elbowed at 15 and extends toward the central portion of the car along the inner face of the cupola wall. A damper 16, preferably of the butterfly type, controls the air delivery and may be closed when, for

delivered through any given passage.

The chambers l are provided with false bottoms 20, preferably inclined to an opening 19, through which solid material may fall to the open longitudinal passage 21 between the false bottom and the main floor of the chamber 1. ended and cinders falling into it are therefore immediately blown out, the air acting with a slight aspirating effect to draw cinders through the opening 19. The cavities 22 between the screens may be similarly provided with means for delivering cinders into passage 21.

Within the heating chamber 10 deflectors 24 direct the air to the front or inlet side of the radiator system. This chamber 10 is located within the cupola, above the level of the deck of the car and is'wholly inclosed by metal walls, the bottom wall 26 being downwardly inclined to form a cinder collecting cavity, and a wooden floor 27 may be provided beneath it, the lower surface of which may be finished to correspond with the interior finish of the car proper. The opening 12 is preferably screened by a suitable grid, and the size of the chamber 10 is such that the air therein has tle velocity so that dust lowed to settle. But the screens in the inlet chambers exclude nearly all dust and cinders and also check the velocity of the air, so that very little solid material will enter the heating chamber 10. The heat radiator in the ch m e s 10 i l of course be subject to This passage 21 is open portion of the control by suitable valves, in correspondence with requirements.

Each car is preferably equipped with two heating chambers 10, one near each end, and one air receiving chamber 1, at each side of the cupola, fitted to the deck sash openings adjacent to the end of the car. Preferably the damper 16 on the side toward which the smoke of the engine blows will be closed and therefore each receiving chamber should be of suflicient capacity to satisfy the requirements for a half portion of the car, a correspondingly located chamber 1 at the other end of the car furnishing the remainder of the air supply. Each chamber 1 is adapted to receive air from either end and therefore the direction of travel is immaterial.

Foul'air .from the floor of the car is delivered through grated openings at 28 into exhaust stacks 29, which extend upwardly through the deck and are provided with suitably apertured caps 30 above the deck. To avoid interference with the seating capacity of the car, these exhaust stacks are preferably located at or near the respective ends of the car, and pass upwardly along the side walls. They preferably pass through the roof between the end of the car and the heating chambers 10. Steam coils o'r ducts 31 preferably extend into these stacks, steam delivery thereto being controlled in each case by a valve 32. \Vhen the car is at rest for any considerable time, air delivery through these stacks may be accelerated by opening these valves and heating the columns of air in these stacks I claim:

1. A car ventilator including the combination with one side wall of the cupola, of a horizontally elongated air receiving chamber secured to said cupola wall at one of its sides, and having screened open ends, a passage connected with the chamber and leading into the cupola, the walls of said passage being adapted to deflect air entering through the screened open ends and directed into the cupola, and a heating chamber within the cupola to which the passage leads, said heating chamber having an opening through which air may pass to the occupied car.

2. A car ventilator including the combination with the cupola of a car, of a horizontally elongated air receiving chamber having one of its sides connected to the side wall of the cupola, and having screened open ends, curved partition walls sub-dividing said chamber in its central portion, and passages leading into the cupola from the respectlve end portions, said partition walls being extended and constituting the inner side walls of the passages.

3. Acar ventilator includingthe combination with the cupola of a car, of a hori zontally elongated air receiving chamber having one of its sides connected to the side wall of the cupola. and having screened open ends, curved partition walls sub-dividing said chamber in its central portion, passages leading into the cupola from the respective encLportions, said partition walls being extended and constituting the inner side walls of the passages, and a heating chamber within the cupola to which the passages lead, said heating chamber having an opening for delivery of air to the occupied portion of the car.

4. A car ventilator including the combination with a car body provided with a cupola, of an exterior elongated air receiving chamber provided at each end withv a transverse screen and an interior obliquely disposed screen spaced from the transverse screen to form a settling chamber, passage walls'leading from the central portion of the receiving chamber to the interior of the cupola, and depending walls forming a cinder discharge passage extending underneath the receiving chamber, the bottom of the receiving chamber having apertures through which cinders may pass from the settling chambers to the cinder discharge passage.

5. A car ventilator including the combination with a car'body provided with a cupola, of an exterior elongated air receiving Ehamber provided at each end with a transverse screen and an interior obliquely disposed screen spaced from the transverse screen to form a settling chamber, passage walls leading from the central portion of the receiving chamber to the interior of the cupola, and depending walls forming a cinder discharge passage extending underneath the receiving chamber, the bottom of the receiving chamber having apertures through which cinders may pass from the settling chambers to the cinder discharge passage. the space within the cupola being subdivided to form a heatingchamber provided with an outlet leading to the interior of the car body and having transversely extending superposed heating coils interposed in the path of the air passing from the receiving chamber to the heating chamber outlet.

6. In a car ventilating system a set of passage ways extended through the deck openings of the cupola and provided with exterior air receiving chambers having air inlets in their front and rear walls, and intermediate, deflecting partitions adapted to direct air from the inlets to the interior of thecar, said chambers being each provided with open passage ways extending along their lower sides from one end to the other, and means for delivering cinders from the air receiving portions of the chamber into such passage ways.

In testimony whereof I afiix my signature.
