SNOVJPLOW.

Application filed February T 0 all whom it may concern:

Be it known that I, GUST HEGLUND, a citizen of the United States, residing at Andover, in the county of Anoka and State of Minnesota, have invented certain new and useful Improvements in Snowplows, of which the following is a specification.

My invention relates to snow plows, and an object in general is to provide a device of this character which is applicable to a motor propelled vehicle for the purpose of removing snow from roads by means operating to throw the snow to the sides of the road whereby the roadway is cleared. Special objects of my invention are to provide means which will throw the snow laterally of the roadway with a great deal of force so that the snow will not be liable to return into the roadway, to provide means which will permit the inclination of the discharge spout to be readily varied, and to provide means which will operate to break up hard snow before it reaches a fan casing from which it is discharged laterally.

The full objects and advantages of my invention will appear in connection with the detailed description, and the novel features of my inventive idea will be particularly pointed out in the claims.

In the accompanying drawings which illustrate the application of my invention in one form,

Fig. 1 is a top plan view of my snow plow. Fig. 2 is a view in central longitudinal section. Fig. 3 is a view in section on the line 3-3 of Fig. 2. Fig. 4 is a View in section on the line 44 of Fig. 2. Fig. 5 is a fragmentary view in section on the line As shown in the drawings, I provide a wheeled frame 10 upon which a drive shaft 12 is rotatably mounted. This shaft may be driven by any suitable motor mounted on the frame and said shaft extends centrally through a circular fan casing containing a number of fan blades 14 secured to the shaft. The rear wall of the fan casing consists of a disk 16 which is secured to the frame 10 by braces 18 and angle members 20. The front wall of the fan casing consists of a disk 22 which is secured to a front casing 24 by braces 26 and angle members 28 and 36. The peripheral wall of the fan casing consists of two semi-circular members 32 and 34 held together by curved plates 36 secured 4, 1924. Serial No. 690,432.

to the semi-circular members adjacent their abutting ends. The marginal portions of these two semi-circular members have secured thereto pairs of inwardly projecting flanges 38 and 40 which respectively engage the margins of the disks 16 and 22 on their inner and outer surfaces. In this manner the members 32 and 34 are frictionally held in place so that they may be turned to vary the inclination of a discharge spout 42 which is secured to the upper peripheral member 32. The forward end of the drive shaft 12 extends centrally through the fan casing and into the front casing 24 and has secured thereto cutting blades 44 positioned within the front casing 24. The shaft 12 is supported adjacent the cutting blades by a bearing 46 secured to a bar 48 passing transversely through the walls of the casing 24 and having its ends secured to arms 50 extending rcarwardly from the front portion of the casing 24. The bar 48 is additionally held by braces 52 extending down from the top of the casing 24 and secured to said bar. Vertical bars 54 depending from the frame 10 secure two channel bars 56 in place, these channel bars projecting hori- Zontally and forwardly beyond the fan casing. Braces 58 connect the front disk member 22 with the channel bars 56. A plate 60 is secured to these channel bars and to the bottom portion of the casing 28 which is extended to produce av scooplike member 62 for scooping up the snow. The front disk member 22 is partly cut out to produce an opening 64 for passage of snow from the cutting blade chamber into the fan chamber, and it will be apparent from Figs. 1 and 2 that the walls of the cutting blade chamber converge rearwardly toward the opening 64 in the manner of a hopper so that the snow is put under pressure as it passes into the fan chamber.

The operation and advantages of my invention will now be obvious. The provision of the cutting blades 44 makes it a much easier matter to drive the snow plow through snow drifts since these blades cut up the caked or hardened snow. On account of the fact that the snow is fed through a constricted passageway into the fan chamber it will be delivered from the discharge spout 42 with considerable force so that it is carried away from the roadway a sufficient distance not to obstruct the roadway and without liability of falling back again into the cleared roadway. As previously described, the peripheral portion of the fan casing carrying the discharge spout may be rotated to change the inclination of the latter whereby the snow may be delivered over high drifts.

I claim:

1. A snow plow comprising a wheeled frame, a fan casing secured to the front of said frame, a discharge spout carried by the peripheral portion of said fan casing, means which permits rotative movement of said peripheral portion with relation to the remainder of said casing whereby the inclination of said spout may be varied, a drive shaft supported by said frame and extending centrally through said casing, and fan blades secured to said shaft.

2. A snow plow comprising a wheeled frame, a fan casing secured to the front of said frame, a discharge spout carried by the peripheral portion of said fan casing, means which permits rotative movement of said peripheral portion with relation to the re mainder of said casing whereby the inclination of said spout maybe varied, a cutting blade casing attached in front of said fan casing, said cutting blade casing being open atits front and communicating with said fan casing through a restricted opening, a drive shaft supported by saidframe, and extending centrally through said fan casing and into said cutting blade casing, fan

blades secured to said shaft, and cutting blades secured to said shaft.

In testimony whereof I hereunto aflix my signature.

GUST HEGLUND.
