STREET OR ROAD SNOWPLOW.

Application filed January 18, 1927. Serial No. 161,777.

of snow from roads or highways which shall,

embody therein, as a co-acting part, an automotive road vehiclewhich shall be of such construction that the component parts shall be readily separable to permit use of the vehicle for any purpose that is desired and to enable conversion quickly and easily even by unskilled workmen of the vehicle, into a, snow plow when desired.

More specifically, the object of my invention is to detachably mount a snow plow on the front end of an automobile, saicl'snow plow having centrifugal fans in operative engagement with the crank shaft of the internal combustion motor-of the automobile.

A still further object is to so construct my device that it may be secured to the front axle of an automobile whereby the snow plow will be guided by the steering wheel of the automobile.

A further objectis to so construct the plow ugal fans will be forced to the side of the road independent of the fans, and also to so construct the plowthat all snow entering the path of the fans will be inbroken and loose condition.

to those skilled in the art.

My invention consists in the constructlon,

arrangement and combination of the various.

parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, ointed out in my claims and illustrated in t e accompanying drawings, inwhich: K

Figure 1 is a top plan view of my snow foruse.

Figure 2 is a side elevation of my com plete device installed on an automobile.

Figure 3. is a rear sectional view of 'my snow plow taken on line 3-3 of Figure 2. A section of the device is cutaway to more successfully illustrate .the mechanism for driving the two centrifugal fans.

I have designated the ordinary automobile by the numeral 10. I have used the numerals 11 and 12 to designate the frame of my snow plow. The members 11 and 12 are pivotally secured to the members 13 and 14 respectively, which are designed to be secured to the front axle 15 of the automobile by U bolts 16. The forward ends of the members 11 and 12 extend downwardly and outwardly and terminate a slight distance above the roadway. Secured to these memhers is my two-way snow plow or shovel 17.

The numerals 18 and 19 designate braces for more securely holding the plow or shovel 17 in'proper position. On each side of the center line of the shovel 17 is an opening 20 and 21, back of each is a centrifugal fan housing 22 and 23. Each of the fan housings 22 and 23 have an outlet ipe 24'and 25 extending upwardly. Rotatably mounted upon each of these outlet pipes 24 and 25 and communicating with each respectively is a distributing pipe 26 and 27 of L construction. Thus it will readily be seen that by turning the distributing pipes, the snow passing therefrom, may be deposited in any desired location relative to the travel of the automobile. Rotatably mounted in each of the centrifugal fan housings in a centrifugal fail 28 and 29. The numeral 30 designates a gear housing position directly back of the two fan housings. Rotatably mounted in the two bearing members 31 and 32 secured to the housing 30, is a shaft 33. Secured to one end of the shaft 33 against relative rotation is a bevel gear 34 in operative engagement with the bevel gear 35 which is per- These and other objects will be' apparent shaft 36 of the centrifugal fan 28.

manently secured to the centrifu al fanecured to the opposite end of the shaft 33 against relative rotation is the bevel gear 37 in operative engagement with the bevel gear 38 which is permanently secured to the centrifugal fan shaft 39 of the centrifugal fan 29.

It will readily be seen by those skilled in the art that if the shaft 33 is rotated, the two centrifugal fans will also be rotated in their respective housings and that if snow entered the openings 20 and 21 it would be forced 'out of the'cdistributing pipes 26 and 27. I have used the numeral 40 to designate a.

sleeve member capable of embracing the crank shaft 41 of the internal combustion engine and having notches 42 capable of engaging the crank shaft pin 43.. Secured to this sleeve 40 is the drive shaft 44 rotatably mounted on a bearing member 4C5 which is cured at its opposite -end i on the crank shaft 41 by the spring 55.

- i other purpose desired.

frame of the plow being pivotally will not be thrown over 'tending flange 56 supported by the hand crank guide case 46 of the automobile. Secured to the forward end of this shaft 44 is a universal joint 47. The drive shaft 48 leading from this joint is square at its forward end and enters and is capable of sliding movement in a square hole in the hollow drive shaft 49 which is se-' to. the universal joint 50. The numeral 51 designates a fourth drive sal joint 50, journaled near its forward end in the bearing members 52 and 52' and extending within the housing 30. Permanently secured to the free end of this shaft 51 is the bevel gear 53 in operative engagement with the bevel gear 54 permanently secured to the shaft 53. By this arrangement when the internal combustion motor is running, both of the centrifugal fans will berotating at a speed relative to the speed of the motor. This is ver advantageous due to the fact that when t e snow is very bad and a great amount of it is to be handled, the car must travel in either low or intermediate ear and the centrifugal fanswill thereby be rotating very fast and will be able to take care of the greater amount of snow; By the to the front axle the variations of the road bed are compensated for. It is because of this construction-that it is necessary for the shafts 48 and 49 to slide one within the other. The universal joints 47 and also help compensate further changing of the position of the snow plow relative to that of the automobile. as follows: 13 and 14 to the axle 15 by the U bolts 16. sleeve 40 onto the crank shaft 41 in. order that the notches 42 therein w'll engage the pin 43. -This sleeve 40 is yieldingly l llt llld e complete device is now ready for use. merel ne'cessar to remove the U bolts 16 and t e low will be disconnected from the automobi e whichmay then be used for any.

It will readily be appreciated that my apparatus is simple in construction and operation and is of-durable construction and is of such character as will admit of operation by any person capable of driving a motor vehicle.

It is apparent that some changes may be made in construct-ion and arrangement of my device without construction also aidsv departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanica-l uivalents which maybe reasonably inclu ed within their scope.
