SNOW-CLEANING APPARATUS. I

' Application filed February To all whom it may. concern:

Be it known that I, ARTHUR S. OLSON, a citizen of the United States, residing at Murdock, in the county of Swift and State of Minnesota, haveinvented certain new and useful Improvements in a Snow-Oleaning Apparatus, of which the followlng 1sa specification.

The present invention relates to a machine for cleaning snow from streets, roadways, and the like, and aims to provide a structure which is capable. ofbeing incoron a truck chassis so that the truck may be driven along the street, roadway or thelike, and the snow picked up from in front of the truck and, conveyed to the side thereof.

. designed.

2 Another important object of the invention is to provide a pair of collecting conveyors which maybe adjusted to the desired height and which may be lifted to an inoperative position.

.Another important object of the inven tion is to provide in'combination with the collecting conveyors a pair of beaters for breaking up the snow as it is being picked up by the conveyors, and further the pro .vision of means whereby these boaters may be adjusted in relation to the conveyors A still further important object of the invention is to provide an apparatus of this nature which is, comparatively simple and efficient structure which may be readily as sembled upon a conventional type of truck, one which is readily assembled or disassembled, strong, durable, not liable to readily get out of order, and otherwise well adapted for the purpose for which it is ;With the aboveandnumerous'other objects in view as will'appearas the description proceeds, the invention residesin certain novel features of construction, and in the combination and arrangement of parts aswill be hereinafter more fully described and claimed. r

In the drawings I Figure 1 is a top plan view of the apparatus embodying the features of my invention,

Figure2 is a side elevation thereof, Figure 3 is a transverse section taken vertically therethrough and looking rearwardly,

Figu taken substantially on the line of Fig- "conveyors A by means of bolts 20 orin re 4 is an enlarged detail section v p 5 mounted a suitable source of power, which I 11, 1925. Serial m. 8,474.

ure 2 looking in the direction of the arrow, and i Figure 5 is an enlarged detail view of the crank and ratchet mechanism assoclated therewith for lifting the beaters.

Referring to the drawing in detail it will beseen that I have illustrated a conventional form of automobile truck, but of course, any other wheeled vehicle could be substituted therefor. In the vehicle which I have illustrated, the numeral 5 designates the chassis thereof on which is mounted up rights 6 by means of cross bars 7, said uprights 6 being of an inverted V -shaped formation in' the present instance. The apexes or upper ends of these uprights 6 form journals for receiving pins 8 for pivotally supporting brackets 9 which in turn support collecting conveyors indicated generally by the letter A. As is shown to advantage in Figure 1 there isfla' pair of these collecting conveyors A which converge toward'their front ends into scoops 11. Each conveyor A includes a pair of spaced vertically extending side walls 12 having the endless conveyor 13 operable therebetween. The

body of this endless'conveyorj 13 has extending transversely thereof cleats 14. Chains '15 are engaged with the edges of the body and with the ends of the cleats and are trainedover sprockets 16 on the end shafts 17 as is shownto advantage in Figure 2.

An inverted U-shaped' frame 19 has its ends fixed to the inner sidewalls of the any other'suitable manner. A pair of

bars

21 and 22 rise from the intermediate portion of the frame 19 and the bar. 22 is a rack bar having its teeth 23 on the inner edge thereof. A standard 24 rises from the forward end of the chassis 5 and a shaft 25 is journaled in the upper end thereof and in a suitable bracket 26 at the dash board of the truck. A crank 27 is provided on the 7 end of the shaft 25' at the dash board and a ratchet mechanism 28 is associated therewith as is shown to advantage in Figure 5. A pinion 29 rotates with the shaft 25 and meshes with the teeth'23 of the rack bar 22 so that by turning the crank 27 the forward ends of the conveyors A and the scoops 11 may be raised and desired. I

At the rear of the chassis 5 there is lowered as I have shown in the present instance merely by way of example as an electric motor--30. A chain 31 is driven by this prime mover 30 and operates a shaft 32 which extends longitudinally of the rear portion of the chassis being journaled under the conveyor B which will be described later. A beveled gear 33 meshes with a beveled gear 34 on the transversely extend ing shaft 35 which is journaled in standards 36. Shafts 37 are connected to this shaft 35 by suitable universal joints 38 and is provided with sprockets 39 for drivlng the chains 15 of conveyors A. These shafts 37 are journaled in brackets 40 on the bottom of the conveyors A. Then the motor 30 is in operation it will be seen that the chains 15 and cleats 14 will travel upwardly over the bottom 13 of each conveyor A for delivering snow collected on the scoops 11 to the upper ends of the conveyorsj for dumping said snow onto the conveyor B A frame 44 rises from the forward end of each conveyor A and the sides thereof are slotted as at 45. A shaft 46 is slidable through theseslots and carries a beater 47 which includes a plurality of radiating blades'a's is evident from an inspection of Figure 2. Cables 48 are connected to journal blocks 49 at the outer ends of the shafts 46 and are trained over pulleys 50- at the upperends of the frames 44. These cables 48 are connected to a common} cable 51 which is attached to a winding drum 52 having an' operating crank 53. By operation of this crank 53 to wind the cable 51 on the drum 52 it will be seen that the beaters 47 may be raised and lowered in respect to the conveyors A. The inner ends of the shafts 46 are provided with sprockets over which are trained chains 55 which extend rearwardly and are trained over sprockets carried by shafts 56 having

universal joints

57 and 58 therein and driven by shaft 59. A bevel gear 60 is mounted on the shaft 59 and meshes with a beveled gear 61 on shaft 62 journaled in standards 63 and driven by chains 64 from the prime mover 30. A clutch mechanism 65 is incorporated in the shaft 62 and is operable from adjacent the drivers seat by member 66 or in any other suitable manner. It will thus be seen that the conveyorsA may be operated independently of the heaters 47 as may be desirable, especially when the snow is rather light and there is no necessity of breaking it up.

The conveyor B extends transversely of the chassis and is mounted on the standards 70 so as to be located below the delivery or upper ends of the conveyors A. This con- .veyor B includes the side walls 71 and 72, the latter being slanted rearwardly and the bottom 73 over which travel the cleats 74 carried by chains 75 trained over sprockets in the end shafts 76 journaled in brackets snow will be collected on the scrapers 11,

broken up by the heaters 47 and delivered by the conveyors A to the conveyor This conveyor 13 will pile the snow collected to the right of the vehicle. It will further be apparent that the conveyors A may be lifted to I an out-'of-the-way position when desired and may be also adjusted in relation to the ground as may be desired by operation of the crank 27; Further, it is to be noted that the heaters 47 may be adjusted in relation to the conveyors A as will be desired depending upon the depth of the snow and when these heaters. are not necessary they may be lifted tothe upper ends of the slots 45 and the clutch 65 opened so that the conveyors will no longer operate. It is thought that the construction and operation of the invention will now be clearly understood without a more detailed description thereof, but it is desired to point out numerous changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from th spirit or scope of the invention as hereinafter claimed and with out sacrificing any of its advantages.

Having thus described the invention, what I claim as new is 1. In combination, a vehicle, a conveyor mechanism r'ockably mounted on the vehicle to extend longitudinally thereof, frame attached to the forward end of the conveyor mechanism, a rack bar attached to the frame, a shaft journaled longitudinally of the vehicle, means for operating the shaft, a pinion on the shaft meshing with the rack bar for raising the forward end of the conveyor mechanism.

2. In combination, a vehicle, a. conveyor mechanism rockably mounted on the vehicle, means for adjusting the conveyor 'mecha nism in relation to the vehicle, a frame including slotted uprights mounted on the forward end of the conveyor mechanism, shafts the forward end of the vehicle and delivering it to an intermediate portion" of the vehicle, said conveyor mechanisms being rockahly mounted adjacent their rear ends on the vehicle, a third conveyor mounted transversely of the vehicle immediately below the delivery ends of the first mentioned conveyor mechanisms for delivering the snow to one side of the vehicle means for operating the conveyor mechanisms, a frame attached to the forward'ends of the longitudinally extending and rockahly mounted conveyor mechanisms, a rack bar fixed to the frame, a

the rack bar, means for rotating the shaft whereby the forward ends .of the rockahly mounted conveyors may he raised or low-- ered, slotted uprights on the forward ends of the conveyors, heaters having shafts slidahle and rotatable in said slotted uprights, means for rotating the heaters, and means for raising and lowering the heaters.

In testimony whereof I aflix my signature.
