SNOWPLOW.

Application filed December 9, 1922. Serial N0. 605,960.

To all whom it may concern Be it known that I, GEORGE S. BRECHT, a citizen of the United States, residing at Baltic, in the county of Minnehaha and State of South Dakota, have invented certain new and useful Improvements in Snowplows, of which the following is a specification.

This inventionrelates to a snow plow attachment for tractors and has for its object the provision of a novel snow plow structure equipped with a supporting frame designed to be clamped upon the front and rear axles of an ordinary tractor, the device including a laterally moving conveyor driven by the power pulley of the tractor so that snow will be scraped up and deposited at one side of the roadway traveled over.

An important object is the provision of a device of this character which is equipped with a rotary heating device located in ad- Vance of, the plow and which is for the purpose of breaking up any encrusted snow so that it may be received properly upon the conveyor and be discharged therefrom.

Another object is the provision of a device of this character in which the blade and forward portion of the frame supporting it are angular in shape so as to form a sloping bank which will prevent caving down of the snow after it has been thrown to one side of the road.

An additional object is the provision of a device of this character which will be comparatively simple and inexpensive to-manufacture, easy to install and operate, efficient and durable. in service, and a general improvement in the art.

With the above and other objects and ad vantages in view, the invention consists in the details of construction to be hereinafter more fully described "and claimed and illustrated in the accompanying drawings in which 4 Figure 1 is a top plan view of the device mounted upon a tractor.

Figure 2 is a side elevation.

Figure 3 is a front view..

The remaining figures are detail views.

Referring more particularly to the draw ings, the letter A designates a portion of a tractor, B represents the draw-bar mounting thereof, C the rear wheels, and D the front axle carrying the front wheels The letter .F' represents the pulley which is provided for the purpose of obtaining power for driving any desired devices. T he tractor is represented very diagrammatically by dotted lines as it forms no part of the present invention but is for the purpose of merely illustrating the application of my for the purpose of holding the frame prop erly in position. The cross member 11 is connected with the draw-bar mounting, as shown at 13.

This frame may be constructed of any desired material though angle iron of some preferred cross sectional configuration is highly advantageous as being comparatively light for its strength.

Carried by the forward ends of the longitudinal bars 10 is an elongated transversely disposed frame 14 upon the forward side of which is secured a shoe or blade 15 which is curved in cross section, as shown, and which is angular in shape. This frame 14 is likewise angular in shape to define an incline 16 which is for the purpose of forming a sloping bank when the device is used. At its ends the frame 14- carries shafts 17 and 18 journaled therein and carrying sprockets 19 about which are trained conveyor chains 20 connected by slats 21 and secured upon the edges of an apron 22. It is preferable that the shafts 17 and 18 carry rollers 23 which support the ends of the apron.

The drive means comprises a horizontally extending shaft 24 which is journaled in suitable bearings 25 carried by vertical supports 26 rising from the frame 14. Intermediate its ends, this shaft carries a pulley 27 about which is trained a belt 28 which is in turn trained about the power pulley F of the tractor. At one end the shaft 24 carries a bevel gear 29 meshingewith a bevel gear 30 mounted on a countershaft 31 which carries a sprocket 32 about which is trained a chain 33 which is also trained about a sprocket 34 on the shaft 17 It is naturally referable that some preferred housing 35 ill) be provided for inclosing the gearing ior preventing it from becoming clogg d with snow, mud, dirt and the like. it is of course apparent that there will he a certain amount of slack on the lower stretch of the conveyor but this will not be any han .licap and mi ght be taken care of in any conventional manner.

Carried by the frame 14 and. projecting in advance thereof are arms 38 terminating in bearings through wl'iieh is journaled' a shaft L0 whi h is horizontally disposed and which carries a hub ll from which radiate beater arms 42, for the purpose of breaking up any encrusted snow. The shaft il) carries a sprocket 43 about which trained a chain. 44 which extends rearwardly and which is trained about a sprocket 4e) on the shaft- 2%.

In order to support the mechanism when the front wheels of the tractor drop into any depressions in the roadway, I provide shoes 46 which are mounted on the undersides of the forward ends of the frame bars 10. These shoes prevent the blade 15 from striking against any obstructions and being broken or otl'lerwise damaged.

lln operation the tractor is propelled along the ground in. the usual manner, and it will be apparent that the power pulley F will operate through the gearing and sprocket and chain mechanism described to drive the conveyor structure and also to rotate the beater. The blade or shoe 15 will naturally cut and scrape up the snow and cause it to be deposited onto the constantly moving conveyor. The slats 21 will prevent the snow from slipping down the inclined portion of the conveyor and will elevate snow to the top of the frame 1 1- where the snow will be distributed upon the side of the roadway. The rotation. of the beater arms insures breaking up of any encrusted or icy snow so that the chunks thereof may be deposited properly on the conveyor to be carried away thereby. Owing to the fact that the blade and transverse frame have an inclined portion, it is quite obvious that the device will operate to cut a sloping bank and in this way caving; in of the pile of snow at the side of the roadway will be prevented.

From the foregoing description and a study of the drawings it will be apparent that I have thus provided a. simply constructed and inexpensive snow plow attachment which may be easily mounted upon a tractor to be carried and operated thereby. The device will very efficiently scrape up and remove'all accumulations of snow, ice and the like from roadways and render them fit for trafiic. (having; to the simplicity of the construction and 'l'ewness of the parts it is apparent that there is nothing to get out of order and that the device should have a long life and satisfactorily performs all its functions.

While I have shown and described the preferred embodin'ient of my invention, it is of course to be understood that I reserve the right to make such changes in the form, construction and arrangement of parts will not depart from the spirit of the invention or the scope of the subjoined claims.
