MACHINE non REMOVING snow.

Application filed November 15, 1926. fierial No. 148,504.

This invention relates to a machine for removing snow and has for its object the provision of a mobile device for taking up snow from a sidewalk or roadway and reducing the snowtoa liquid state without the application of heat for the purpose of such reduction.

'lhcse objects are attained by the mechanism hereinafter described, it being understood that changes may l e made in the device within the scope of the claims, without departing from the spirit of the invention or sacrificing any of the advantages thereof.

In the drawing:

Figure 1 is a plan view of the machine.

Figure 2 is a longitudinal sectional view.

Figure 3 is asection taken on. line 3-3 of Figure 2.

Figure 4 is an end elevation of the machine.

Figure 5 is a sectional view taken on line 5 of Figure 3 and Figure 6 is a view in elevation of a perforated disk forming a part of the device.

Referring to the drawing.v the numeral 1 designates a frame provided with attaching ledges 2, whereby the device may be mounted on a wheeled vehicle or on a sled.

A cylindrical casing 3 is secured to the frame 1 and is closed at the rear end as shown at 4, providing a saturating; chamber. A plow or scoop 5 is secured at the forward end of the drum 3. and is inclined downwardly toward its front end to provide a cutting edge 6 which travels close to the surface of the roadway.

A main shaft 7 is mounted in bearings 8 and. 9 located at the front and rear ends respectively of the casingfi. Oil cups 10 are provided for lubrication of the shaft 7 in its bearings. The bearing 8 is supported in the forward end of the casing by a spider. 11 se cured to the casing as shown at 12. A cutter 13 is mounted for rotation in the front of the casing, the cutter conuorising a pluralityof adjustably mounted cutting or shaving blades l t, the active edges of which projectthrough openings 15 in a disk 16 forming; a part of said cutter. The disk is secured to the shaft '4 as at 17 and is provided with tapered en largements 18 adjacent the openings 15 into which bolts 19 are threaded for adjustably securing the blades to the disk.

, The outer end of the shaft 7 is provided with a cone-shaped member 20 which rotates with the shaft '5' above the scoop or plow 5,

'connections from the shaft 21.

whereby the mass of snow is dividedand evenly distributed to the cutter.

A longitudinally extended counter shaft 1 is mounted in the frame directly beneath the shaft 7 and receivesmotion from the shaft 7 through the gears 22 and 28 secured'to shafts 7 and 21 respectively.

A belting compartment 24 is formed beneath the casing 8 through which the shaft 21 extends. Mounted in the compartment 2d and secured on the shaft 21 for rotation therewith is a beating drum or roller 25 having a serrated outer surface as shown. The serrations may be of any desirable configuration best adapted to reduce snow brought into contact therewith to a liquid state. Se-

cured to the shaft 7 at the rear of the casing is an abrading member in the form of a perforated disk 26 adapted to rotate against the snow and slush in the casing and by fric tional engagement with the same cause it to meltrapidly.

Tanks 27 are provided at either side of the chamber 24 and communicate therewith through a plurality of pipes 28. The lower end of the pipes are located near the bottom of the compartment 24:, the discharge endof the pipes enter the tanks 2'? near the top thereof. A pump 29 is located at the rear of the machine and is driven by chain and sprocket The intake of the pump is connected to one of the tanks 27 as shown at 31 and discharges through the pipe line 32 to a header 38 located in the top of the casing 3. In the present instance the header has been shown as a single pipe having a series of perforations for directing water at various angles to thereby saturate the entire contents of the chamber. The header however may comprise a plurality of'pipes connected to accomplish the result desired. The tanks 27 are connected by pipes 34:, so that water may pass from one to the other. i

A relief cook 35 is provided at the top of the tank for permitting overflow therefrom whenthe tanks are filled. If desired a slatted conveyor 36 maybe mounted on the scoop 5 as shown and driven bysuitable gearing 37 connected to the shaft 21. Plugs 38 are threaded in the bottom of the compartment 24 so that the water may be withdrawn and the compartment cleaned.

In operation of the device power is applied from any suitable source to the shaft 7 and the machine is moved along the roadway under its own power or otherwise as desired. Snow is scooped upby the plow and moved toward the cutting head being assisted in its, ascent of the scoop by the conveyor. The

distributor separates the mass of snow and delivers it to the cutting head. The'cutters having been previously adjusted to take the requisite bite into the snow mass, adjustment of the bite depending on the consistency-of the snow. The snow enters the cylinder from the cutters and is saturated by water i from the header as it passes to the rear of the cylinder to be acted on by the swiftly revolving abradingdisk, The snow mass by-this time has been reduced'to slush and falls on' the beater, which itwill be noted, is travel ing at a high peripheral speedas compared to the speed of the cutting headand abradmg disk. It will also be noted that rotation of the beater is in an opposite direction to that of thecutters and disk mounted on the drive shaft so that an added frictional engagement is had with'thesnow as it is swirled by-the beater Within the melting chamber.

YVhen the chamber is filled with water to the level of the outlet end of the pipes 28, :it flows into the tanks and is withdrawn therefrom by the pump to be reintroduced to the interior ,of. the casing through the header. VVa-ter is thereby circulated through the deviceto assist in, melting the snow-,the

surplus escaping through the relief cock.
