SNOWPLOW.

Application filed March 5, 1924. Serial No. 697,146.

' a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Snowplows, of which the following is a specification.

This invention relates to improvements in snow plows particularly adapted though not necessarily limited in its use for removing snow from streets, roads or highways, and

one of the objects of the invention is to pro-- vide an improved motor propelled vehicle like structure of this character which may be readily controlled and operated from the vehicle.

A further object is to provide improved mechanism for handling and conveying away the snow and improved meanswhereby the snow handling'mechanism may be adjusted or shifted with respect to thevehicle so as to position such mechanism as desired with respect to the work to be performed, and which mechanism may also be shifted or swung upon the vehicle so as not to interfere with the travel of the vehicle when the apparatus is not in use for the removing or shoveling of the snow. I

A further object of the invention is to improve and simplify a machine of this character and increase the efficiency and speed of operation thereof in the handling of the material being operated upon, and

at the same time produce a machine which wvill be simple, durable and comparatively compact in construction'and effective in operation.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in. substantially the construction, combination and arrange- -ment of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention, and, in whicl1 Figure 1 isa top plan view of the apparatus.

Figure 9 is an end elevation of Figure 8.

Figure 10 is a detail top plan view with parts omitted and parts broken away of the mechanism for shifting the snow handling mechanism aboutits pivot with respect to the supporting structure.

Referring more particularly to the drawings the numeral 15 designates a suitable wheel supported vehicle, having the wheels 1617, the wheels 16 being the steering wheels and being controlled by means of steering mechanism, 18, which latter is located within the enclosure 19 for 'the operator.

The vehicle is propelled by a motor mounted thereupon (not shown) but preferably located under the hood 20.

The vehicle may be of any desired construction and of any desired size, and the motor for driving the vehicle is preferably located adjacent the rear of the vehicle.

The snow handling mechanism is located at the other or forward end of the vehicle and consists of a casing 21 of any desired size. This casing is provided with an inlet opening 22 through the upper wall thereof for the reception of the snow or material to be handled, and is also provided with a discharge outlet opening 23 to which latter opening is connected a spout 24. This spout may be of any desired size and configura tion and is preferably arranged so as to deliver the material from the casing 21 to one side of the path of movement of the vehicle 15.

The casing is supported upon the forward end of the vehicle for pivotal movement with respect thereto, in any desired or suitable manner but preferably by means of brackets 25 connected with the casing and which brackets are j ournaled upon bearings 26 carried'by the vehicle structure 15. J ournaled in the bearings 26 is a shaft 27 which has connected with it for. rotation therewith a beveled gear 28, for a purpose to be hereinafter described.

Arranged within the casing 21 is a rotor which consists preferably of a disc 29 connected with a hub 30, and which hub may beof any desired size. Carried by the disc 29 are a plurality of radially arranged blades, each of the blades being of any desired height, a portion of each blade being deflected laterally to another portion of the blade and along a line 31 extending lengthwise of the blade intermediate the longitudinal edges thereto to form a portion 32 and a deflected portion 33. The portion 32 of the blade'is anchored as at 34 tothe disc 29 so as to be arranged perpendicular thereto while the deflected portion 33 of the blade overhangs the discs and the free longitudinal edge 35 of the portion 33 of the blade 31 diverges from the inner end of the blade toward the outer end thereof, the inner end of the blade being disposed adjacent the hub 2o 30, while the outer end of the blade is disposed adjacent the periphery of the-disc 29. This free edge 35 of the blade 33 may be shaped to form a cutting edge 36 or may have a cuttersecured thereto, and the surface of the portion 33 together with the cutting edge of such portion of the blade is of a helical formation. 7

This shape of blade is particularly advantageousin devices of this character for the reason that as the rotor travels at a greater velocity at its periphery than adjacent its axis, the blades will be so arranged that they will take in approximately the same proportionate amount of snow in the neighborhood 5 of the axis as at or in the neighborhood of the periphery of the rotor. The difference in the speed of rotation at these two points is compensated by the difference in the; angle of the cutting edge of the blade adja- 40 cent the hub and the periphery by reason of the helical formation of the cutting surface of the blade. The rotor thus constructed substantially fills the casing 21 and the diameter of the rotor and lengthof the blades is substantially equal to the diameter-of the 'opening '22 in th casing 21 and beneath which opening the rotor is located, the hub 30-of the rotor being disposed at substantially the diametric center of the said' opening.

With this arrangement it wil-l-be manifest that, snow which passes into the casing 21 through the opening 22 will be caught by the blades of the rotor and will be conveyed thereby to the means of the beveled gear 28, which meshes with another'beveled gear 36 secured to a shaft 37 and to which shaft 37 the rotor is secured in any desired or suitable manner such as by means of a key or fastening device 38. Theishaft 37 is journaled in a bearthe casing 21, together h ing 39, preferably arranged in the bottom of the casing 21 and also in a bearing 40 supported in any desired or suitable manner preferably by means of a spider or arms 41 secured to the top of the casing 21 andextending across the opening 22. I

It will therefore be manifest that when the shaft 27 is rotated a rotary motion will be imparted to the rotor within the casing 21, through the medium' of the gears 28 36, and as the casing 21 is mounted for pivotal movement with respect'to the supporting vehicle or structure it will be manifest that the gears 28-36 will remain in mesh during the pivotal movement of the casing 21 with respect to the supporting vehicle and will also continue to drive the rotor in any position to which the casing 21 has been adjusted. I

The casing 21 may be moved about its pivot in any desired or suitable manner but preferably by means of arms 42, one of which is preferably arranged adjacent each side of the supporting structure and are pivotally connected with the supporting structure for movement in unison, preferably by means of a ban or rod 43, having suitable bearings upon the supporting structure. Connected by one end to each of the arms 42 is a link 44 and the free ends of these links are pivotally connected as at 45 with the rotor casing 21, so that when the bar or rod 43 is rocked in its bearings it will be manifest that through the medium of the link connection 44 between the arms and the -rotor casing 21, the latter will be swung about its pivot and will be maintained in its adjusted position by reason of these connections.

Any suitable means may be provided for rocking the shaft 43. A simple and efficient means for accomplishing this result includes a toothed segment 46 which is connected with the rod 43. The teeth of the segment are engaged by a worm .47 carried by a shaft 48 journaled in suitable bearings .49 and this shaft 48 extends lengthwise of the vehicle structure 15 and preferably terminates within the enclosure 19. A beveled gear 50 is connectedwiththeshaft 48 and this beveled gear meshes with another beveled gear 51 ona shaft 52, which latter is adapted to be rotated by means of a hand control device 53.

It will therefore be -manifest that the rotor casing21 may be swung about itspivot in any direction and to any desired extent by the operation of the. hand control device 53 and when so operated the arm and link connection 42-44 between the shaft 43 and with the worm and toothed segment'46, the casing will be maintained in its adjusted position. 7

Any suitable means may be provided for rotating the shaft 27 but it is preferably rotated from a suitable motor device 54 mounted upon the vehicle structure and which motor may 'be of any desired or suitable type. Connected with the shaft of the motor 54 is a pulley 55 over which a belt 56 passes. This belt in turn passes over a pulley 57 carried by the shaft 27.

If desired a suitable clutch 58 may be provided for controlling the driving'connection between the motor 54: and the shaft 27. This clutchldevice 58 may be of the ordinary and well known type, which may be operated by hand to render the pulley 55 active or inactive with respect to the motor shaft.

If desired and when the apparatus is being transported, the driving mechanism of the rotormay be rendered inactive and at the same time the rotor casing 21.may be swun about its pivot so that it will be folde so to speak, upon the supporting structure so as not to interfere with the transportation of the device.

The snow is directed to the rotor casing preferably by means of a scoop like device 59, which .is secured to the rotor casing 21 and encompasses the opening 22. This scoop maybe of any desired size and configuration so that the forward edge 60 thereof extends for a considerable distance in advance of'the opening 22 in the rotor casing 21. The edge 60 is preferably substantially straight and is of a length to preferably extend beyond the sides of the vehicle structure. The sides "61 of the scoop extend for any desired.

height above the rotor casing to a point to 'thevrear of the opening 22 so that when the vehicle is advanced and the edge of the scoop is placed in proximity to the work or snow the snow will travel into the scoop to be delivered through the opening 22 in the rotor casing without compressing the snow.

If desired a hoodlike closure 62 may provided for a portion of the scoop and is pivotally mounted as at 63. This closure is provided as a means for preventing the snow from traveling out of the top of the scoop and is pivotally mounted so that the snow 1n the scoop will automatically control themsiug movement thereof. Theclosure 63 is pivotally mounted so that it will automatically open and thereby prevent the snow from packing or wedging in the scoop. A

which flexible element 63 may be provided for limiting the opening movement of the hood.

As ameans for assisting in directing the snow, which has been gathered into the scoop, into the opening 22 of the rotor casing, there may be provided a deflector 64, is arranged in the rear of the opening 22 within the scoop and is shaped to partially encompass the opening. This deflector is preferably inclined to the bottom-of the scoop and preferably extends entirely across the scoop.

With this improved construction it will be manifest that during the operation of the apparatus the snow will be constantly in motion or traveling from the time that it is picked up by the scoop until it is delivered through the spout 24 and furthermore the snow will be prevented from packing in the scoop.

The rotor casing is mounted for pivotal portionate amount of snow will be taken into the rotor by the blades in the neighborhood of the axis of the rotor as at the periphery of the rotor.

With this improved construction and are rangement it will be manifest that the opening 22in the casing and through which the rotor is supplied with snow, will at all times be covered by the snow being supplied by the scoop. This is accomplished by reason 'of the peculiar construction of the scoop, the deflector 64 and the hood 62, all of which direct the snow from all points about the periphery of the opening 22 thercthrough and to the rotor, with the result that the rotor will be completely covered by the snow, thereby preventing the rotor from driving air through the casing as such air would cause the rotor to operate inefliciently.

With this improved form of scoop device 59 in combination with the sides 61 thereof, the snow will be lifted and retained in an unpacked condition in its passage from the ground to the rotor,'and ,,the deflector .64, will after the portion of the snow over the rotor has been removed by the rotor, push the advancing snow into the rotor feed'openinggwithout compressing the snow.

y the arrangement of the steering wheel 16 behind and spaced a considerable distance from the snow handling mechanism, the

steering of the vehicle will be greatly facilitated and rendered easier in operation by reason of the fact that a greater leverage of the vehicle will be obtained.

Furthermore, by mounting the scoop and I the rotor for pivotal adjustment, it will be manifest that the leading edge of the scoop may be positioned at any desired angle with respect to-the surface of the ground to compensate the depth of the snow being operated upon and to control the advancing movement of the scoop.

While they preferred form of the invention has been herein shown and described it is to be understood that various changes may be" 5 made in the details of construction and in the combination and arrangement of the sev- 'eral parts, within the scope of the claims, without departing from the spirit of this invention.
