snow REMOVER.

Application filed August 20, 1926. Serial No. 130,524.

My invention relates to improvements in snow removers7 and the object of my improvement is to supply a self-propelled and actuated device of this class which is adapted for successful empioyment for removing and delivering to a desired place of deposit snow accumulated upon highways or other places.

lVith the foregoing and'other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

l have accomplished the above objects by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in whichFig. 1 is a side elevation of my improved Asnow remover, with parts in vertical longitudinalv section or broken away. Fig. 2 is anuenlarged central vertical longitudinal section ofthe step-bearing for the rotor, with ele` ments' in side elevation.

The snow remover shown is borne upon a frame 1 of longitudinally arranged and 'connected side beams having depending' trusses 2stiffened by struts 48. The frame l is mounted upon rear driving-wheels 4 which are positively rotated by means of a motor and driving connections in a bodyr of a truck pattern as at 3 of well-known type which will not be further described, being clutch controlled as usual by means of a pedal device 47. In the cab of this device is the usual steering wheel 44 with rod connection 45 to the steei'able forward carrying wheels 5, and in the same cab is another clutcli cont-rol pedal 46 to control a motor 7 under a hood G placed upon said frame anterior to the cab device 3 and spaced therefrom for convenience in manipulating starting cranks of both 1notors.

Upon the frame 1 anterior to the hood 6 and motor 7, is a hollow upright casing 25 terminating upwardly in a hollow conical part 26. The front only of the casing 25 below the conical part 2G is open.

Upon the top part of the cone 26 is rotatably mounteda snow-delivery device 27, hollow and elbow-shaped at 28 to deliver substantially horizontally away fromA the' casing and preferably to either side thereof in depositing the snow upon the ground alongside or in any receptable or conveyance ranged alongside. The basal cylindrical part 29 of the device 27 is a flat annulus having a circumferential row of sockets 30 in any of which a `detent'upon a medially pivoted arm 31 isdesigned to removably fit to thereby hold the device 27 in an adjusted position to deliver at any desired angle relative to the casing 25-26 and to assure that the deliveryshall be in the path of movement of any prevailing wind. The arm 31 is resiliently controlled by a flat spring 32 mounted on the cone 26 lto normally keep the detent thereof seated in one of said sockets 30 yieldingly.

The numeral 33 denotes an inclined plate which is rigidly supported at the rear upon the forward part of the frame 1 and is braced intermediately by means of lbraces 38 whose upper ends arek connected to the upper part ofthe casing 25, and by means of other side braces 34 from its forward end leading to the rear part of the casing 25. The numeral 36 denotes a forward section plate or scraperv pivoted on pintles 35 to the forward'edge of theplate' 33 and has a sharpenedforward scraping or cutting edge. The scraper' plate 36 has one or more slide slices 37 Afined upon its lower face near its cutting edge to slid-ably ride upon the way ahead. A canopy plate 41has its rear endpivoted at 40 to the upper part of the casing 25 to be inclined forwardly and inclose'the open front of said. casing and has a forward uppergcurved part 42 which is immediately above the pintles 85. The canopy 'plate 41 may have depending Yside parts l43 which serve to inclose the space between the plates 41 and 33 partially for a purpose to be described. l

Just to the rear of the forward carryingwheels 5 the forward part of the frame includes a stiff metallic base plate9, centrally apertured at 17 to be traversed kby a vert-ical rotary shaft 16. This shaft projects upwardly within and nearly to the cone 26 of the casing 25 and its upper end is. rotatably mounted in an apertured bearing 24 on the forward end of a rigid bracket-alan` 23. Upon that part of said shaft which is posi tioned within said casing are fastened a plurality of upwardly inclined vanes 21 vof different lengths as arranged successively upwardly7 the vanes being laterally tilted to serve both as snow cutters and propellers to engage snow delivered to them from the snow blocks falling` to the rear ofthe raisedV rear end of the inclined plane 33 and reduce them to powder to be thence. drawn upwardly by the suction producing action of the vanesI 21. The numeral 22 denotes upwardly inclined bars which are fastened upon the outer terminations of the vai-ies 20- and 21 and serve to shave the face ofthe snow wall presented to them while these bars arerapidly rotating, to break up the snow intofragments to be more effectively dealt with and delivered upwardly by said vanes.

The lower end of the rotary shaft 16 is mounted in an anti-frictionstep-bearing shown in said Fig. 2. A hollow housing memberis removably secured upon thev lower face of thel base-plate 9 concentric with lsaid shaft 16 which extends'downward- `ly thereinto and through a depending aper tured integral bearing-sleeve 11 thereof into a lower hollow housing A member 12 which is removably mounted upon said housing 10.

A bevel-pinion 19 is fixed upon the shaft 16 within the upper part of the housing member 10 and is in mesh with a bevel-gear 18, preferably in about a two to one ratio, the gear 18 being also within -said housing member 10 and fixed upon an end of a ro'- tatable longitudinally arranged shaft` 8 which enters said member by wayV of a sleeve-bearing. Thev shaft 8 may be the extended crank-shaftof a motor 7' in the rear.v

Thev lower part of thelower housing inember 12 is contracted to have a threaded bearing seat for a threaded stem 14 of a stepbearing cup 13 within the member 12-co`n taining an anti-friction ball supporting the lower termination of said vertical shaft 16, The cup hollow may be wider than the diameter of said shaft to receive and hold a quantity of lubricating substance, of a suitable kind. The lower and projecting endV of the stein 14 may be shaped to engage a wrench 'used when necessary to vertically adjust the position ofthe cup bearing 13 in truifng the position of the shaft 16.

The operator may, by the means described, operate the mechanisms ofthe de-VV vice,- both in propelling it forwardly, and inrotating the rotorin the housing25. The

forward swinging plate section 36 mayride up and down over'variations in the supporting surface adjustingly, and the forward cutting edge of this platel will enter snow deposits and penetrate same to receive them thereupon to be receivedfupon the rigid inclined plate 33 and then bev-delivered into the` housing to be treated `by the vanes of the but small resistance to the snow when moving rearwardly over it toward the rotor.

This-device is particularly designed forv city streets or country highways, and the in clinedplates 36-83 are such as to function with but slight side draft when they enter s:

snowV deposits which are positioned I obliquely upon onev side of the way where the plow or excavating parts passinto` the drift yonly at one side,

Having described my invention, what'l claiml as new, and desire'to secureby Letters Patent, is: y
