Specification of Letters Patent.

Patented Nov. e, recs.

Application filed September 20, 1905. Serial No. 279,371.-

To all whom it may concern.-

Be it known that we, EARL O. WALKER, residing at New Albany, in the county of Floyd and State of Indiana, and ERA C. J ACOBSON,

residing at Louisville, in the county of J eiler' which will direct a stream of fluid under pressure into the path of the rising dust created in the movement of the vehicle, which fluid will act by its pressure on the dust to deflect the latter and overcome its, tendency to rise and settle on the' vehicle and on the occupants thereof. In its preferred adaptation and as applied to automobiles driven by steam or gasolene engines the errhaust steam or gases are utilized to accomplish the end referred to. V

In connection with a dust-deflector of the above ty e means are provided for directing a jet of uid against the moving parts of the driving mechanism and gearing-of the vehiore to prevent the dust froin settling thereupon and impairing the same.

To this end the invention consists in certain novel. cpmbinations'of elements and in certain peculiarities in the constructiiin and arrangement of arts, substantially as hereinafter described and particularly pointed out in the subjoined claims.-

In the accompanying drawings we have illustrated the aforesaid preferred embodiment of our invention. A

In said drawings, Figure 1 is a plan View of a portion or" a motor-vehicle provided with verted plan view of the fluid-discharge pipes, showing a slightly-modified arrangement in that they are not connected with the mufiler shown in Figs. 1 and 2. i 4

The same clmrzuators of reference designate the slime parts in tho/several views.

A designates a portion, of the body of a motrn' vehicluv of any suitable construction. a designates the rear wheels of said vehicle, and a the axle thereof. The driving mechanism of said vehicle comprises aneugine, (in- I Fig. 2 is a'section there-- of out e line 2 2 of 1 1g. {and Fig. 3 1s an'indicated at B,) which is adapted to exhaust a gaseous or other fluid under pressure. Said, engine is suitably connected with the wheels a or axle a, for example, by a means comprising a shaft 5, driven by said engine and provided with gears b, connected h chains 2 with gears 5 mountedon the she a/-.

1 designates the exhaust pipe or outlet,

leading from the exhaustport of the engine or engines, Suitably connectedtherewith is a pipe 2, having outlets arranged at the place or aces where it is desired to dischar c said exhaust fluid for the purpose of de ecting the rising dust and preventing itfrorn set tling or'accumulating on the passengers or on thegvehicle or its driving mechanism. The arrangement shown in the drawings is greatly preferred and comprises a dischargetuhe- 3, which extends across the rear end of the vehicle and has downwardly-extending ends 4, located rearward of the rear wheels at and bent longitudinally to conform to the curvature of the faces of the rubber tires of said wheels. This tube is formed through-' out its length with'a series of discharge-apertures 5, which are directed rearward'and" downward,-. whereby the dust. rising from the ground behind the vehicle will be de-' ilectecl by the exhaust fluid issuing from said apertures and: will thereloy he prevented from settling on the car or the passengers. Said tube 3 is located, preferably, below and slightly rearward of the iraine of the car, and between the rear ,end pi said "frame and said tube there is placed a deflectinglate 6, comprising a sheet of thin metal, c 0th, rubber, or other material, which extends in a rearwardly and downwardly inclined plane from the rear end of said frame to said tube 3. B.

this means the air-currents created beneat the car in the movement thereof and the dust stirred up by the front wheels and entrained in said currents will strike said plate 6 and be deflected downward thereby and caused to iiow rearward, where they meet and are fur ther deflected by the currents issuing from the discharge-apertures 5 of the pi e 3.-

Suitably connected withthe ex aust port or 'outlet from the engine are other pipes \leading-the exhaust fluid to and discharging it against portions of the vehicle or its driving mechanism which it is desired to keep free from dust.' As exempliiicatory of this portion of the apparatus we have shown a pipe 7, which extends across the car from the grit, and it will also be understood thatsaid tubes may be connected with any suitable portion of the exhaust system without departing from the spirit of the invention.

It will be apparent that the means described for utilizing the exhaust fluids to deflect the dust will-also serve as a mufiier and that the pipe 2 may be connected directly with exhaust-port of the engine'; but it may be preferred to use a muflier such as is indicated at 10, and in such event the discharge pipe 2 is preferably connected with said muffler, as shown in Fig. 1.

The construction, operation, and advantages of the invention will be apparent from the foregoing, and it will be understood that the construction illustrated is merely exemplificatory of a suitable form of the inventionas applied to one type of vehicle. The inven tion is not restricted to said detail form shown, it being readily understood that the tube 1 maybe modified in shape or design according to the particular construction and design of the car on which it is to be used, and the discharge-apertures 5 in tube 3 may be inade of any size, shape, or number, so that the issuing exhaust will accomplish the work desired. Moreover, it is evident that different cars and their peculiar construction will require different forms of our invention and different arrangements of its parts both in relation to one another and in relation to the car itself, and said parts therefore may be of different construction and arrangement to means, comprising a. conducting means for a dust-deflecting fluid, having discharge-span tures in proximity to the rear wheels of the vehicle and adapted to deflect the dust raised by said wheels, and also having a dischar aperture in roximity to a moving part of t e driving mec anism and directed toward the same.

3. In a motor-vehicleg a dust-deflecting means, comprising a conducting means having connection with the exhaust-port of the engine of said vehicle and provided with dis char e-apertures in proximity to the rear whee so the vehicle and adapted to deflect the dust raised by the same and also having a discharge-aperture in proximity to a moving part of the driving mechanism and directed toward the same.

4. In a motor-vehicle, a dust-deflecting means, comprising a conducting means for a dust-deflecting fluid, said conducting means having a pipe adapted to extend across the rear of the vehicle and provided with a series of discharge-apertures in proximity to the rear wheels of said vehicle and also between said wheels, and a discharge-pipe having a discharge-aperture in proximity to and directed toward a movin 'part of the driving mechanism of the vehic e.

5. In a motor-vehicle, a dust-deflecting means, comprising aiconducting means for a dust-deflecting fluid, said conducting means having connection with the exhaust-port of the engine of said vehicle and comprising a pipe extending across the rear of the vehicle and provided with a series ofdischarge-apertures arranged in proximity to the rear wheels of the vehicle and also between said wheels, and a discharge-pipe having a discharge-aperture in proximity to and directed toward a moving part of the driving mechanism of the vehicle.

'6. In a motor-vehicle a dust-deflecting means, comprising a muffler having connection with the exhaust-port of theengine of said vehicle, a pipe havin connection with said muffler and provide with dischargeapertures arranged to direct the exhaust fluid in the path of the dust raised b said vehicle and to deflect said dust ,and a isohargepipe having a discharge-aperture in proximity to and directed toward a moving part of the driving mechanism of the vehicle.

7. In a motor-vehicle, a dust-deflecting means, comprising a muffler having connec* tion with the exhaust-port of the engine of said vehicle, and a pipe having connection with said muffler and extending across the vehicle-body and in proximity to the rear wheels thereof and provided along its length with discharge-apertures arranged to direct the exhaust fluid in the path of the dust raised by the vehicle and to deflect said dust, and a discharge-pipe having a dischargeaperture in proximity to a moving part of the driving mechanism of the vehicle.
