CAR-VENTILATOR.
SPECIFICATION forming part of Letters 'Patent No. 764,079, dated July 5, 1904.
Application filed May 16, 1903. Serial No. 157,466. (No model.)
To all whom tim/(ty concern,.-
Bc it known that 1, FREDERICK W. SYMMEs, a citizen of the United States, residing at St. Matthews, in the county of Orangeburg and State of South Carolina, have invented new and useful Improvements in Car-Ventilators, of which the following is a specification.
This invention relates to car-ventilators, the invention having' for its object to p'rovide an apparatus whereby foul or vitiated air is removed from the ear and its place supplied by fresh pure air, which is filtered prior to its entrance to the car, and thereby freed from dust, smoke, and other impurities. By means of the invention hereinafter described the car may be closed throughout both in winter and summer and yet fresh pure air supplied in desircd quantities at all times to the occupants of the car. 1
Vith the above general objects in View the invention consists in the novel construction, combination, and arrangements of parts, as hereinafter fully described, illustrated, and claimed.
In the accompanyingdrawings, Figure 1 is a vertical longitudinal sectional view taken substantially -centrally of the car Vand showing the fresh-air-inlet devices employed at each end of the latter, together with the means located at one end of the car for drawing off foul or vitiated air through a pipe extending longitudinally of the interior of the car. Fig. 2 is a similar view in continuation of the structure represented in Fig. 1 and showing the fan and operating devices therefor employed at or near the opposite end of the car for maintaining agitatidn of the air within the ear. Fig. 3 is a vertical transverse sectional view taken through the end portion of the car shown in Fig. 9. Fig. 4 is an enlarged detail plan view of the hinged frame which carries the driving-wheel and by means of which motion is communicated from one of the car-axles to the fan or pump, &c.
Like reference-numerals designate corresponding parts in all gures of the drawings.
Referring in the first instance to Fig. 1 of the drawings, 1 designates a pipe extending along the top of the car and providedV with one or more openings 2 at a suitable point or points for the purpose of admitting foul or vitiated air to the pipe by means of which such air is carried away. The openings 2 may be of any desired size and may be covered with wire fabric or gauze. At or near one end of the car the pipe 1 is bent to extend downward, as shown at 3, andv is placed in communication with a suction-pump 4, arranged in any convenient place, preferably near the car-floor, said pump when in operation serving to exhaust air from the pipe 1, and thereby drawing thefoul air from the car.
The operating device for driving' the suc tion-pump 4 consists, essentially, of a swingf ing frame 5, which is hinged at one end on a shaft 6 and which carries at its opposite end another shaft, 7, upon which is fastened a driving-wheel 8, adapted to rest upon one of the car axles 9 and be driven frictionally thereby. Connected with the driving-.wheel 8 is a sprocket-wheel 10, around which runs a sprocket-chain 11, which also passes around another sprocket-wheel, 12, on the shaft 6, thereby transmitting rotary movement to said shaft 6. Upon the same shaft 6 is mount# ed a crank-13, and from said crank a pitman 14 extends to and connects with the piston-l rod 15 of the suction-pump 4. Pivotally connected with the frame 5 is an operating latchbar v16, which extends upward through the flooring of the car and is provided at its up. per end with a handle 17, while at an inter-A mediate point said bar is provided with a hook or lip 18, adapted to be engaged with a pin or shoulder 19 when the bar is elevated for the purpose of holding the hinged frame 5 upward and driving-wheel 8 out of engagement with the car-axle 9. 90 designates an exhaust or eduction pipe leading from pump 4 outward and preferably terminating beneath the car-body. In the operation of the pump the foul air is drawn from the top of the car throu'gh the pipe 1 and pump 4 and expelled through the exhaust-pipe 20. Vhen the apparatus above described is not needed in use, the operating latch-bar 16 is drawn upward and latched over the pin or shoulder 19, thus lifting the driving-wheel 8 out of contact with the car-axle.
In order to introduce fresh air to the car,
IOO
I provide duplicate funnels 21 at each end of the car, which funnels each supplies fresh air to an air-pipe 22, leading directly into the car and preferably extending' in a horizontal direction. At a suitable point intermediate the extremities of each of the pipes 22 I arrange a filtering box or chamber 23, partially or wholly filled with some filtering material, such as sponge, as shown at 24C, whereby the air admitted through the funnel 21 is caused to pass over or through the filtering material. Said filtering material is preferably kept in a moistened state by supplying water or other liquid in the desired quantity thereto. For this purpose reference is had to a water-tank 25, arranged in the upper portion-and near the roof of the car, said tank being provided with pipes 26, which lead downward to the filter, the flow of water through the pipes 26 being controlled by means of regulating valves or cocks 27. The funnel may be covered by wire gauze or fabric, as shown at 28, and the discharge end of each of the pipes 22 may also v ated by means of a horizontally-disposed shaft 31, connected by bevel-gears 32 to an upright shaft 33, which extends downward through the floor of the car, where it is connected by bevel-gearing at 34 with a short horizontal shaft 35, mounted in suitable bearings beneath the car-body. Motion is communicated from one of the car-axles 9 to the shaft 35 by means of a hinged frame 36, carrying sprocket-wheels 37 and 38 at its opposite ends connected by a driving-chain 39. On the same shaft with the sprocket-wheel 37 is a driving-wheel 40, which is adapted to rest on and bedriven by the axle 9 or raised out of contact and engagement therewith by means of an operating latch-bar 41, similar in all respects to that, 16, above described and having the same function and method of adjustment. VVh'en the drivingwheel 40 is in contact with the 'axle 9, motion is communicated through the connections described vto the fan 30. By raising drivingwheel 40 'out of contact with the axle the fan is thrown out of operation. The fan may also be thrown out` of operation by means of a shifting-lever 42, arranged within convenient reach in the car, said shifting-lever engaging a sliding' clutch 4-3, movable into and out of engagement with the hub of the bevelgear at the upper end of the upright shaft 33, as illustrated in Fig. 2.
From the foregoing description it will be seen that the apparatus is Well adapted to` draw foul or vitiated air from the upper portion of the car and expel the same beneath the car-body. At the same time fresh air is admitted to the car, such air passing through the filter and coming in contact with the moistened material with which the liltcr is supplied, and where the fresh air is admitted to the car it is taken up by the fan and distributed throughout the car. In this way a perfect and continuous circulation of fresh air is maintained in the car, enabling the doors and windows of the car to remain closed, if desired.
One or more hinged frames provided with driving-wheels 8 and 40 may be utilized for driving the suction-pump and fan; but as it is ordinarily necessary to draw off the foul air simultaneously with the supply of fresh air one of such hinged frames and drivingwheels may be utilized for driving both the fan and suction-pump, in which case the shaft 6 may be provided with the crank 13, sprocketwheel 12, and one ofthe pair of bevel-gears for transmitting motion to the upright shaft 33, which is geared to the fan-shaft 31.
Having thus described the invention, what is claimed as new is- 1. A car-Ventilating apparatus, comprising a perforated pipe extending longitudinally of the interior of the car, and having a downwardly-'extendingmember at one end, a pump located at one end of Vthe car, with the casing of which' the said pipe member is in communicatiom said pump havingan air-discharge pipe lcadingthrough the bottom of the car, a transverse shaft below the pump and beneath the car, having at one end a sprocket-wheel, and provided with a crank, a pitman connecting said crank with the piston-rod of the pump, a frame hinged at one of its ends to said shaft and provided at its other end with a sprocket-wheel, a sprocket-chain connecting the two sprocket-wheels, and a drivingwheel carried by the free end of said frame, and resting on one of the `axles of the car` to be driven thereby, as and for the purpose described.
