SNOWPLOW.

Application led i'l'uly 27, 1925. Serial No. 46,410.

Our invention relates to snow plows and has for its ob]ect the provlsionof an apparatus which may be coupled to they front end of a tractor or other motor impclled vehicle'and operated from the said vehicle to create a suction or air blast whereby snow taken up from a road will be deposited at one side of thepath made by the machine. A further object of the invention is to provide simple and easily operated nieans whereby snow may be scraped from aroad, then reduced to a tine condition free of lumps, and then blown to a point\at the side of the path. The invention alsoseeks to provide a device which may be produced at a low cost, which will be eiiicient in operation and which will be strong and durable. The invention is illustrated in the accompanying drawings and consists in certain novel features which will be particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a side elevation of our im` sills we erect a frame 3 which is preferably formed from angle bars and may be of any detailed design possessing the requisite strength. ySecured upon and projecting forwardly from the sills 1 and the frame 3 is a scoop consisting of a downwardly and forwardly inclined bottom plate'4 adapted to r'un upon the ground and scrape therefrom the snow to be removed. This bottom plate 4 has its side edges in divergent relation so that the front of the plate is wider than its rear edge and at the side edges of the said plate are rigidly secured side plates 5 which lform component parts of the scoop and serve to retain the snow uponpthe bottom plate and direct-it into the beater or breaker as the plow progresses. Rigidly supported at the rear of the side plates 5 is a'hood 6 which lits over a beater or breaker consisting of a hub 7 and arms 8 rigidly lecured to ,and radiating from the hub and disposed transversely .of the machine so that, as the snow is taken up and caused to move relatively rearwardly in the travel of the machine, it will be brought against the rotating beater or breaker so that the large lumps will be disintegrated and the snow passed rearwardly in such condition that it may be eti'ectually acted upon by the discharging fan. The hub 7 of the. beater is secured upon a longitudinally extending shaft 9 mounted in ksuitable bearings upon the hood Gand the supporting frame and vequipped at its rear end with arpulley 10 about which is trained a belt 11 whereby the said pulley 10is operatively connected with a pulley l2 secured upon the engine shaft of the tractor to be actuated thereby. Within the: upstanding frame 3 and secured rigidly thereto is a housing 13 having an opening in its front side concentric with the beater. Arranged within this housing 13 is a fan consisting of a hub 14 secured upon the shaft 10 and arms 15 secured upon the hub 14 tangential thereto and carrying blades 16 at their outer ends. Upon reference to Fig. 4 more particularly, it will be noted that the hub 14 is angular in cross section and has flat sides, the arms 15 being secured to the fiat sides of the hub. The arms are arranged in pairs and the blades 16 are secured to Iand connect the outer ends of the arms in each pair. Between the arms is a disk or circular plate 17 to which the blades 16 are Aalso secured, as indicated at 18, the

`strengtl'i of the structure being thereby increased and the snow being more efectually broken up and discharged. It will be noted that the diameter of the central bracing disk 17 is less than the diameter of the housing so that the blades 16 are disposed between the edge of the diskand' the side of the housing, the snow being consequently drawn into the housing below the edge of the disk and positively engaged by the blades to be forcibly driven from the housing. Rising tangentially from one side of the housing isV a spout 19 which may be carried to 'any desired height and is equipped at its upper end with a laterally extending hood 20.

In operation, the machine 4is driven forward over the line of the path to be cleared by the operation of the tractor in the usual manner. As the machine progresses, the scoop 4 will take up the. snow and the fan and the beater will be positivel rotated at a high speed under the power o the tractoi engine. The rotation of the fan will create a suction through the housing 13 and the discharge spout 19 which will Very materially vaid in effecting the rearward passage of the snow which will be drawn into the. range of the beater so that it will be broken up by the action of the same. From the beater the snow will be drawn directly into the housing 13 and will be ositively engaged by the fan so that it will e driven into and through the spout 19, the physical impact of the fan blades cooperating with the suction of the fan to effect positive and rapid discharge of the snow.

The scoop is not rigidly supported but is pivoted, as indicated at 21, to the front ends of the sills 1 and upon the upper front corner of the frame 3 is mounted a. rock shaft 22 having crank arms 23 fixed to and upstanding therefrom. Links 24 are pivoted to the said crank arms and to the sides 5 of the scoop and to one of the crank arms is pivot-ed a rearwardly extending connecting rod 25 which passes to and is pivoted to a hand lever 26 vfulcrurned in any convenient manner upon the tractor frame. This hand lever is equipped with a wellknown latch mechanism 27 cooperating with a holding bar 28 secured upon the tractor so that by properly manipulating the hand lever the scoop may be set to run at a higher or lower point or may be raised to an inoperative position at will.

[From the foregoing description, taken in connection with the accompanying drawings, it will be lseen that we have provided a very simple, compact and eflicient apparatus whereby a path may be easily and rapidly formed after a heavy fall of snow.

Having thus described the invent-ion, we claim:

1. A snow plow comprising a scoop7 a bea-ter arranged =at the rear end of the scoop, a housing in rear of the beater having a tangential dlscharge spout, a fan within the housing concentric with the beater and comprising a hub having flat sides, arms secured to the flat sides of the hub tangential to the axis of the hub, blades secured to the outer ends of said arms, the arms being arranged in pairs and the blades connecting the arms of each'pair, and a reinforcing disk arranged between the arms and secured to the hub and to the inner edges of the blades. v.

2. 'A snow plow comprising a frame to be secured to the frame of a tractor, a scoop pivotally supported on the front end of said frame, a rock shaft mounted on the front of the frame at the top thereof, crank arms on the rock shaft, links connecting the crank arms with the scoop, a hand lever to be mounted on the tractor, a connecting rod connect-ing the hand lever with one of said cranks, a beater mounted at the rear end of the scoop, a fan in rear of the beater, a shaft common to the beater and the fan, and means for operatively connecting said shaft with the power shaft of the tractor.

3. A snow plow comprising sills to be secured to the frame of a tractor, an upright frame carried by the sills near their front ends, a scoop pivoted to the front ends of the sills, a beater at the rear of the scoop, a hood supported from the front of the upright frame and extending over the beater, a housing secured in the upright frame and rising therefrom and having a lateral discharge, a fan in said housing in axial alinement with the beater, means for connecting the fan. and the beater With the shaft of the tractor, a rock shaft on the upright frame, cranks on said shaft, links connecting the cranks with the sides of the scoop, and a hand lever to be secured on the tractor and operatively connected with one crank on the rock shaft.

In testimony whereof we affix our signatures.
