Referring now in detail to the drawings, Il Ydesignates a snow removal device, embodying the invention.. The same cmprises a truck or vehicle Il provided with a gasolene engine i2, or other'motive means for operating the snow loading means, to be described hereinafter. The vehicle Il comprises a frame I3 supported on wheels I5'. The engine i2 is mounted on the frame I3, preferably between the front and rear wheels of the vehicle.

Mounted on the frame i3, are a pair of spaced brackets II formed with horizontally aligned bearings l1. Pivotally supported on the bearings Il is a longitudinalworm tube I8, to the sides of which are fixed pivot pins or brackets I9 journalled within the bearings I 1. The brackets Il are located mediately the end of the tube Il. Interconnecting the frame I3, and a portion of the tube located above the brackets I8., are hy- 35 draulic jacks 20 for swinging the tube I8 about its pivotal axis. The hydraulic jacks may be of any suitable well known construction.

Tube i8 is formed with an opening 2i adjacent its lower end and-at the top side thereof. At the 401ower end of tube I8 is an end wall 22. The upper end of tube I8 is open, said open end of the tube being formed with a ange 23 located in a plane inclined to the axis oi the tube. Thus, when the tube is in snow loading position, the flange 23 is substantially in vertical position, as shown in Fig. l of the drawings. Fixed to the upper end of the tube il is'a bracket 25 carrying a thrust bearing 2t located axially of the tube i8.' The lower end wall 22 of the tube is formed with a 50 central bearing 30. vMorunted on and between the bearings' and 26 is an axial shaft 3| passing through the tube I8, and carrying a worm blade 33.

At the upper end of tube Il, yis a chute l! l formed with a flange '36 contacting flange 2l..

The chute 88 is adapted to be rotated relatively to iiangell and ilxed thereto by means of bolts 81, passing through registering slots 88 in the contacting flanges 28, 88. It will be noted that the chute 88 has an opening 88 at the top thereof through which the bracket 28 passes.

Fixed to the lower end of tube I8 is a casing 88 communicating with the opening 2| at the lower end of the tube I8. The casing Il comprises a substantially semi-annular wall 88, top wall portions 41 extending rearwardly from wall I8, and a bottom wall or shovel or apron portion 48 inclined downwardly and rearwardly from tube I8. Wall portions 81 are parallel to wall portion I8. The wall portion I8 however extends further than the wall portions. The lower or rear edge 49 of wall I8 is adapted to contactfthe ground. so that snow may be shoved or moved be rotated about its pivotal axis without affectup said wall into the hole or opening 2| in each side of the opening 2| are parallel, transverse rotary shafts 50 each carrying at its lower end a bevel gear 5|. Atttached to the wall 48 and depending therefrom, are brackets 82 carrying a rotary transverse, horizontal shaft 58 carrying bevel gears 84 meshing with the bevel gears 8|. v

Mounted on one side of tube I8, adjacent the lower end thereof, is a bearing 88 in which is rotatably mounted a shaft 6| carrying a bevel gear 62 meshing with the adjacent bevel gears 5|. On shaft 8| is also a sprocket wheel 88, connected by s-procket chain 88 to a sprocket wheel 81 on shaft 3| which carries the worm 88.

It will now be understood that rotation of shaft 6I will cause rotation of the worm 88 in a direction to carry the snow upwardly in the tube I8, and at the same time, causes rotation of shafts 50 in opposite directions.

Withinthe casing 45, and rotatably mounted on shafts 50 and keyed thereto, are fan like members 18, each provided with a pair of blades 1|. It will be noted that the blades overlap and when members 18 are rotated in the directions of the arrows of Fig. 5, snow will -be moved into the opening 2| to the lower end of the tube I8. Blades 1| will move in such direction when worm 33 rotates to -push the snow up the tube.

Means is provided for rotating the shaft 8|. To this end, one of the pivot brackets |8 which is xed to the tube I8, is formed with an axial opening 80, and journalled therein is a shaft 8| carrying a bevel gear 82, and a sprocket wheel 83. Fixed to the tube I8, is a. bracket 88, formed with a bearing 86, supporting shaft 8| and located between the bevel gear 82, and the sprocket wheel 83. Said bevel gear and sprocket wheel are fixed to the shaft 8| on opposite sides of the bearing 88.

Bracket 85 further" carries a bearing 80 at right angles to the bearing 88. Journalled in the bearing 88 is a shaft 8| carrying a. bevel gear 82 meshing with the bevel gear 82. Shaft 8| is interconnected to shaft 8| by a connecting rod 98 having universal connections 88 and 8l at the ends thereof with said shafts.

0n the frame I3 is a shaft lil'adapted to be rotated by the engine I2, and connected thereto through a clutch which may be operated by rotation of a shaft IOI on the frame. On shaft |08 is a sprocket wheel |02 connected by a sprocket chain |88 to the sprocket wheel 88. Thus, when the motor I2 is operating4 and the clutch connects the motor or engine to the shaft ing the driving gear for the worm or fan members.

Means is provided to break up pieces of ice or hard snow within the worm tube. To this end, there is fixed to the bottom of the tube a plurality of inwardly extending radial pins II8, the worm blade being formed with slots I I, through which the pins pass as the worm rotates. The lower end of the worm blade may be formed with teeth or serrations |I2, to help break up the snow and ice.

Means is provided to release the clutch if pieces of ice too hard to be broken up get into the tube I8. To this end, tube I8 is formed with an opening |28 at the bottom thereof, and adjacent the lower or rear end thereof. Extending downwardly from the tube Il on opposite ysides of the opening |28 are ears I2I carrying a transverse pin |22. Pivoted to the pin |22 is a lever |28 projecting upwardly into tube I8. Fixed to the tube |8 is a bracketl80 carrying a rotary shaft I8I disposed at right angles to the axis of the tube I8. 0n one end of shaft I8| is an ann |82 connected yby a link |38 to the lower end of the pin |28, below the pivot pin |22.

Fixed to the opposite end of shaft |8I is an arm 185 connected by a link |88 to anarm |81 fixed to the clutch shaft I8I. A coil tension spring |88 connects arm |81 with a xed part of the arm, to retain the clutch in operating position. Should a particularly hard piece of ice get into the tube and swing the lever or pin |28 about its pivotal axis |22, such action will cause rotation of shaft |8I and through link |88, rotation of the clutch shaft IOI t'o disconnect the engine from the driving gear for the worm and fan members. The worm blade is formed with a slot IIIa to permit'the upper end of lever |28 to pass as the worm rotates.

Fixed to the underside of the casing I8 is a skid jack |88 of any suitable construction, to support the lower end of the tube I8 and casing 45.l

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense. l,

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
