To all whom it may concern: y 7 Be it known that-L-MAnKs J. TULLY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have-invented certain new and useful Improvements in Snow Removers, of whichthe following is a specification.

This invention relates to snow removers and the rimary object of the invention is 10 to provi e an improved machine for effec tivelyand quickly removing snow and the,

like from streets and roads with a. minimum amount of'labor and expense.

Another object of the invention is the provision of an improved means for reducing the snow to a liquid condition so as to permit the same to readily flow through a sewerage system, so that the hauling of the snow toa distant dumping ground is eliminated, thereby permitting the continuous uninterrupted use of the machine for removing the snow from the streets.

A further object of the invention is to provide an improved means for permitting the snow removed from the streets or roads to travel a relatively long distance in the machine so that the snow will be thoroughly acted upon by the means'for reducing the same to a liquid state, thereby insuring the 30. effective operation of the machine.

A further object of the invention is the provision of a plurality of high powered torches or flame throwers for reducing the snow to a liquid, the torches or flame throwthe snow whereby the snow will be quickly and easily melted. y

A further object of the invention is the provision of an improved means for spray- 40 ing the snow removed from the streets and roads with water or the like so as to reduce the bulk thereof, a novel pumping system being embodied in the machine for insuring of the eiiective spraying of the water, means for raising the temperature of the water. also being provided, so that the snow will be. par- I tially melted or reduced to slush when the water is sprayed on the same.

A further object of the invention is the provision of an improved snowremoving machine embodying a plow or scraper, an endless conveyor for 'receiving -the snow from the plow for elevating the same, a series of superposed endless conveyors arranged in rear of and below the first coners being so arranged as to act directly on veyor for increasing the travel of the snow through the machine, means for spraying the snow with water as the same is propelled through the machine by the conveyors, and flame throwers or torches for acting directly on the snow as the same falls upon the uppermost conveyor of the superposed conveyors. I

' A further object of the invention is the provision of a tank; arranged below the superposed conveyors for receiving the water from the snow, the water in the tank being treated from the exhaust and cooling systemsof the power plants of the machine, means being provided for utilizing the heated water for spraying the snow, and'means also being provided forpermitting the oyerfiow of the water from the tank to be directed toward the street gutters or sewers.

A still further object of the invention is the provision of means for heating the conveyor utilized for elevating the snow to the series of superposed conveyors so as to prevent the sticking of the snow to the conveyor thereby insuring the efiective dumpmg of the snow on the superposed con veyors. With these and other objects in View, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part of this specification, in which drawings:

. side channel beams 10 and the cross beams 11. The side beams 10 adjacent to their forward terminals support the semi-elliptical springs 12 which carry the dead axle 13.

The terminals of the dead axle 13 have secured thereto in the usual manner the ordinary. steering stub axles 14: on which are rotatably mounted the relatively heavy ground steering wheels 15. The wheels 15 may be of any desired construction,- provided with solid heavy rubber tires. The steering stub axles 1a are also provided with the usual outwardly extending arms 16 which are connected together by the transversely extending connecting rod 17. This rod 17 has'operatively connected thereto the bell crank 18v which is in turn connected to a depending crank 19 by a link 20. The

- crank 19 is secured to a transversely extending shaft 21 for movement therewith. The shaft 21 is rotatably mounted in suitable bearings 22 bolted or otherwise secured to the side channel bcarns'lO. The terminals of the transve'rseshaft extend beyond the side beams 10 for a considerable distance, the purpose of which will hereinafter more fully appear and the terminals of the shaft have keyedthereto the crank arms which are in turn pivotally connected to the upwardly extending connecting rods 24. The upper terminals' of the connecting rods 2st are pivotally connected to cranks 25 which are secured to a second transversely extending shaft 26, which is supported by the housing for the endless conveying mechanism-C which will be hereinafter described. The shaft 26 extends transversely of the machine and is positioned directly below the operators cab 27 and this shaft has keyed orotherwise secured thereto a suitable worm wheel 28, which meshes with a worm 29 carried by the steering post 30. The steering post 30 is provided with the usual steering wheel 31. Thus 'it can be seen that upon movementof the steering wheel, the stub shafts 14 will be turned.

A power plant 32 is arranged intermediate the ends of the frame or chassis B for operating the various conveyors, sprayversely extending shaft 37.

has keyed thereto a relatively small sprocket 89 shaft 34; of the internal combustion engines is extended forwardly and provided with a worm which meshes with a worm wheel 36 keyed to or otherwise secured to a trans- The shaft 37 wheel 38 around which is trained a sprocket chain 39. The sprocket chain 39 constitutes the means for operating the drive mechanism a0 of the snow remover. A suitable brake mechanism 41 is carried by the shaft 35 37 for decreasing orstopping the rotation of the shaft when desired. This brake mechanism is operated in any preferred manner from thedrivers cab 27.

The driving mechanism 40 of the snow re- 99 mover includes a pair of spaced longitudinally extending bars as which have mounted on their upper surface spaced bearings 43 in which are rotatably mount ed a pair of spaced transversely extending shafts 44.. These shafts stl have keyed .to. the terminals thereof the relatively broad sprocket wheels' lli and a traction belt 46 is trained around the wheels. The traction belt 46 has its outer surface provided with a plurality of transversely extending cleats 47, which form means for permitting a firm grip to be obtained on the ground. lVhile the driving mechanism 40 for the snow remover has been shown to be of. the

caterpillar type, it is to be understood that ordinary drive wheels may be provided it so desired. The axle 44 which supports the forward relatively large sprocket wheels 45 has keyed thereto a relatively large drive 1 sprocket wheel 48 and this sprocket wheel has trained around the same the drive sprocket chain 39. Thus itcan be seen that an effective means has been provided for operating thedriving mechanism from the internal combustion engine 33. It is also to be understood that suitable clutches and control devices for the internal combustion engine 33 are provided and these means are to be operated from the cab 27 in the usual. 0

or any preferred manner. The internal combustion engine 33 is provided with a suitable water cooling system which includes a radiator 49 which is secured to the rear end of the channel beams 10. The radiator 49 is of any preferred construction and has connected thereto in the usual manner the return and supply water pipes 50.

An exhaust pipe 51 is also provided for the exhaustmanifold of the engine 33 and this secured thereto in any pre- 7 neea aa? .terminals of these brackets carry suitable rollers 53 and 54 which are adapted to engage respectively the upper and lower runs of the traction belt 46 so as to prevent any slack in the belt intermediate the sprocket wheels l5. The snow receiving'and elevating' mechanism C is arranged at the forward end of the snow removing machine and the same projects forwardly of the frame or chassis B and below the drivers cab 27.

This mechanism includes a frame 55 which is connected-to the chassis or frame B in any preferred manner. The frame 55 includes upper and lower inclined walls 56 and 57 and connecting side walls 58. The cab 27 is located directly on the upper wall 56 of the framewhich forms a convenient means for supporting the same. The forward and rear ends of the side walls 58 rotatably support transversely extending I shafts 59 and 60 and these shafts have keyed or otherwise secured thereto at spaced points sprocket wheels 61 which have trained around the same drive sprocket chains 62.

The drive sprocket chains 62 are connected by transversely extending flights 63 and these flights and sprocket chains constitute the-endless conveyor for engaging the snow in the machine. The transversely extending flights 63 are of substantially hollow -V- shaped construction in cross section and are secured to thexsprocket chain in any preferred manner. The flights are preferably of hollow configuration for a purpose which will be hereinafter more fully described. The side walls 58 of the frame 55 also support intermediate their ends a table 64 which is arranged in spaced parallel relation to the upper and lower walls 56 and 57. This table forms a means for' supporting the upper run of the sprocket chains 62 and forms a support for the snow to be elevated. This table is provided with a plu-- rality of 'perforations's'o as to permit any snow which might be reduced to a liquid state to seep therethrough. This conveying mechanism extends slightly beyond the lower wall 57 so that the snow being elevated will be propelled beyond the same. The means for introducing the snow on the conveying mechanism and for scraping the .snow from the street or roads includes a shovel or scraper plow 66. The shovel or scraper plow 66 includes the side walls 67 and the lower wall 68. The rear end of the lower Wall is provided with an inwardly extending arcuate extension 69 which is adapted to engage the forward curved end of the bottom wall 5?. The walls 6? of the shovel or plow are pivoted in any preferred manner to the side walls 58 of the frame 55 so as to permit the plow or shovel to be raised or lowered. The lower end of the bottom wall .68 of the plow or shovel is adapted to scrape the snow orthe like from the surface of the street or road over which the snow removing machine is being propelled, and, to protect the forward edge of the bottom wall, a

gitudinally extending side members 72and the forward ends of these members 72 are connected by partial elliptical leaf springs 73 with the side channel beam 10 by any preferred type of shackle 7 The rear ends of the side members 72 are connected by means of a transversely extending semielliptical spring 75 to the rear ends of the side channel beams 10. The means employed for connecting the driving mechanism 410 to the frame reduces the transmission of shockstothe machine incident to the travel thereof over roadways. The side beams 10 have secured thereto at spaced intervals the upstanding vertically disposed channel beams 76 which form means for supporting and bracing the housing 77 for the snow travel increasing mechanism D which will be now described. The housing 7 7 for the snow travel increasing mechanism D ineludes side walls 79 which may be formed a continuation of the side walls 58 of the frame The side walls 79 have also secured thereto the front and rear walls 80 and 81. A depending tank 82 is formed on the housing and is adapted to receive the liquid resulting from the snow after the same has been melted. The snow travel in creasing mechanism D- includes a plurality of su erposed horizontally disposed conveyors S6, 84- and 85. These conveyors are all constructed substantially alike. and a description of one will suffice for all. As shown. the conveyors each include pairs of spaced sprocket chains 86 which are trained around pairs of spaced sprocket wheels 87 which are keyed or otherwise secured to pairs of spaced shafts 88 which are rotatably carried by the sidewalls 79 of the housing. These chains are connected by transversely extending hollow if-shaped flights or blades 89 which are adapted to engage the snow and propel the same through the machine.

The upper runs of the conveyors S3, 8% and are iorttd by horizontally disposed 1 i iq (0 -1' .1 I- pciloi m. suppc m tr e, a n 11L 1 a e by the side walls ,9 of the housalso carried ing. The conveyors are also separated by transversely extending" ,pzu'tition plates or platforms 91 which form means for receiving the snow as the same drop off of the tables 90. It is to be'undcrstood that the conveyors may be positioned at various distances apart so that as the snow decreases in bulk, the conveyors will be able to effectively engage and propel'the same through the machine. Each of the transversely,extending partition plates or platforms 91 extend forwardly from the wall 81 of the housing'l? and terminate short of the front wall 80. The inner surfaces of the front wall and the rear wall and 81' are suitably curved to conform to the arc in-which the flights or blades 89 swing as the same ride. over the sprocket wheels 87.' Thus it can be seen that as the snow is brought up the inclined endless conveyor formed by the

sprocket chain

62 and 63, the same will be dropped on the uppermost horizontally disposed conveyor 83 which will carry the snow rearwardly and deposit the same on the uppermost partition plate .or platform 91. The lower run of the uppermost conveyor 83 will then propel the-snow off of the platform I where the same will drop on the intermediate conveyor 84: which will again carry the snow rearwardly and deposit the same on theintermediate platform or partition 91. The lower run of the intermediate conveyor 84: will-then propel the snow forwardly and off of the intermediate platform and on the lowermost conveyor 85. The lowermost conveyor 85 wil] again carry the snow rearwardly and deposit the snow on the lowermost platform or partition plate 91, after which the lower run of the lowermost oonveyor will propel the same into the tank 82 provided for that purpose. Thus it can be seen that the snow is given a tortuous passage through the machine and is acted on by means for reducing the same to a liquid pipe is positioned therein.

state. The tank'82 rests upon the upper surface of the side beams 10 and an overflow The upper end of the overflow pipe is provided with an inverted goose neck 96 and when the water reaches a predetermined height in the tank the same will ride into the overflow pipe. The lower' end of the overflow pipe. extends outwardly of and below the tank and terminates adjacent to one ofthe side beams 10. The outer end of this pipe is adapted. to have a hose or the likev connected thereto so that the water from the tank'will be di rected toward a gutter or sewer.

The water spraying device E provided for decreasing the bulk of the snow and for partially melting the same includes a storage 'ple 101.

tank 97 which is secured, in place by suitable bracketsOS. The water is stored in the tank 9'7 by means of a suitable water pump 00 which is secured to the frame Bin any preferred manner in advance of the internal combustion engine 32, which is connected thereto in any preferred manner for operating the same. The inlet pipe 100 of the water pump 09 extends rearwardly to the tank 82 andis provided with a suction nip- Thus it can be seen that the water for the pump is taken from the tank 82. The

outlet pipe 102 of the water pump 99 is conneoted to the storage tank 91'. has connection wlth a cross plpe 103, one terminal of which extends upwardly as at This tank 97 104 and communicates with a substantially U-shaped pipe 105, the legs of which extend over the endless conveyor formed by the chains (52 and the flights or blades 63. Thus it can be seenthat as the snow reaches the upper end of the conveyor the snow is thoroughly sprayed with the water from the tank 82, which effectively reduced the bulk of the snow and reduces the same to a slush. The opposite end of the cross pipe 103 has connected thereto a substantially U-shaped pipe 106 the legs of which extend into the housing 77 and these legs have connected thereto for commumcation therewith the longitudinally extending pipes 107. The

pipes 107 are disposed abovethe upper and intermediate partition plates or platforms 91 and it will be seen that as the snow or slush falls upon the plates or'partition the snow is thoroughly sprayed with the water.

Means is provided for heating the water in the tank 82 so that the temperature of the .water will be raised when the same is sprayed uponthe snow so that an effective means will be provided for reducing the snow to -a slush. The means provided for heating the'water consists in extending the exhaust pipe 51 of the internal combustion motor 38 into the tank 82 and the terminal of the exhaust pipe 51 is connected to a substantially U- shaped pipe 109. The legs of the'U-shaped pipe 109 are bent inwardly to ward each other as at 110 and then upwardly and inwardly in spaced parallel relation to the .legs of the' U-shaped pipe. Thus it can be seen thatya'c'Oillike bodylis provided for u the exhaust pipe, so that a relatively large amount of heat radiating surface is provided. The-cooling system for the internal combustion engine 32 also obtains its supply of water from the tank-82 and the return pipe 111 thereof empties into the tank and it can be seen that this will also tend to raise the temperature of the water. The inlet pipe 112 extends into the bottom of the tank and is provided with a suitable perforated suction nozzle which prevents the entrance of dirt and the-like into the pi e.

The endless conveyor formed y the chain 62 and the flights or blades 63 and the conveyors 83, 84 and 85 are driven by the internal combustion engine 32. The crank shaft 113 of the internal combustion engine 32 is provided with a worm 114, which meshes with a suitable worm wheel keyed or otherwise secured to a transversely extending shaft 115 rotatably mounted in suitable bearings 116 bolted to thelongitudinally extending side beam 10. This shaft 115 is op eratively connected to a second transversely extending shaft 117, by means of a suitable sprocket chain and wheel connection 118. The shaft 117 extends transversely across the frame B and has the terminals journalled in the forward pair of vertically disposed channel beams 7 6. The shaft 117 is operatively connected to the longitudinally extending shaft 119, by means of a'worin 120 which meshes with a wormwheel 120 carrid by the shaft 119. The shaft 119 is utilized for driving the water pump 99. One of the vertically disposed channel beams 76 is provided with suitable bearings for supporting a vertically disposed shaft'121. The vertically disposed shaft 121 is connected by means of bevelled gears 122 with the transversely extending shaft 117. The shaft 121 is utilized for driving the superposed conveyors 83, 84 and 85 and the forward shafts of these conveyors have their terminals extended through the channel beam 76 and has keyed to the outer end thereof the bevelled gears 123. The bevelled gears 123 mesh with suitable bevelled gears 124 which are keyed to -the vertically disposed shaft 121. Thus it can be seen that the superposed conveyors are efiectively operated.

The conveyors 83 and 84 and 85 have the tables thereof resting upon suitable channel beams 126 which are also provided bracing the housings 79. Angle irons 127 are also secured to the side walls 79 of the housing and form supports or guides for the blades or flights 89 and the terminals of the blades rest upon the angle irons. Means is also provided for tensioning the chains,

86 of the conveyors 83, 84 and 85,. This means for tensioning the chains consists of providing bearings 129 which receive the rearmost shafts 88 of the conveyor. The.

sides 79 of the housing 77 for the conveyor and therearmost pair of channel beams 7 6 are provided with aligned slots 130 through which the shafts'SS extend. The bearings 129 have the terminals thereof provided with openings for the reception of screws 131, which are mounted in suitable brackets 132 carried by the channel beams 76. The screws 131 have fitted thereon nuts 133 and 134. The nuts 133 engage against the outer side ofthe brackets 132wh1le the nuts 134 engage the opposite faces of the bearings 129. It can be seen that by 'adjustin the nuts the bearings can he slid longitudisprocket Wheels 135 and 136 have trained around the same a drive sprocket chain 137 and thus it can be seen that when the shaft 121 is rotated by the internal combustion engine 32 the inclined conveyor formed by the chains 62 and the flights 63 and the superposed conveyors 83, 84 and 85, will be operated. The snpporting table 64 for the chains 62 has its terminals secured to longitudinally extending inclined beams 138, which also provide-means for effectively bracing the table throughout its leno'th. The table is further braced by means of longitudinally extending beams 139, which are arranged in spaced parallel relation to the side channel beams 138 and these beams 139 are supported by'suitable crossbraces 140. The plates 63 are also held in their correct position durv ing their passage over the table by means of angle irons-141, which are also secured to the sidewalls 58 of the frame 55. The

frame is also braced throughout its length by frames 142, which extend entirely around the frame. The internal combustion engineg 32 and 33 are cranked in any preferred manner and as shown a hand crank 144 is provided for the forward engine 32. The frame B has secured thereto in any preferred manner the supply tank 145 which is adapted to receive the fuel for the engines 32 and 33 and the same are fed from the tank 145'in' any preferred manner.

The exhaust p1pe 146 of the internal combustion engine 32 is extended into the frame 55 for the forward end of the conveyor as at 147 and the exhaust gases escaping into the frame efi'ectively heat the snow so as to ermit the temperature thereof to be raised. he exhaust pipe terminates in the casing directly-between the upper and lower runs of the conveyor andas the flights 63 are of hollow formation the exhaust gases will have a tendenc to flow into the same and thereflame throwers 148 and these torches or flame throwers are arranged longitudinally and transversely of, the housing "77. As shown a plurality of torches 149 are car ried by the side walls 79 of the housin '7 and these torches are located directly a ove the uppermost conveyor 83 and are adapted to project the flame directlyon or into thesnow as'the same rides by on the conveyor. The rear Wall 81 also carries a plurality of torches or flame'ejectors 150 and it can be seen that as the snow is brought rearwardly toward the rear wall 81, they snow will be acted directly upon by the torches. The batteries of the torches or flame projectors 148 are connected in series by means of a feed pipe 151 which communicates With'the supply fuel tank 152 which is arranged at the rear end of the frame or chassis B. A suitable-supplemental supporting frame 153 is built on the rear end of the chassis for supporting the fuel tank. -A hand operated valve 154 is interposed in the fuel supply pipe 151 so that the fuel for the torches or flame projectors may be out off or controlled.

Also independent hand operated valves 155' are provided for' each one of the flame projectors so that the same may be individually controlled. The tank 152 may contain any suitable or preferred type of fuel for the torches or flame projectors, such" as kerosene, gasoline or the like. The fuel is forced from the tank 152 into the feed pipe 151 by means of air pressure and this air pressure is maintained by a relatively small air pump 156 which is actuated from the crank shaft of the internal combustion engine 33.

To prevent the pressure in the tank from 1 risin beyond a predetenninedidegree, a

suita 1e automatic air-escape valve 157 is provided. This valve permits the air to escape from-the tank after a predetermined pressure has been reached.

In operation of the improved snow remover,the machine is driven to the place where the snow is to be collected. The scraping plow or shovel 66 is then lowered until the projecting prongs or teeth 7 0 are in en gagement with the ground. The machine is 'then started and it will be seen that the plow 66 will effectively collect the snow and direct the same on the endless inclined con- I veyor formed by the chains 62 and flights 68. The flights 63 will carry the snow up the inclined table 64 and as the snow reaches the upper end of the same, the snow will be thoroughly sprayed and washed by the water from the U-shaped pipe 105. This will effectively decrease the bulk of the snow and have a tendency to reduce the same to a slush. The flights 63-are heated by means of the exhaust gas from the engine 32 which will prevent the sticking of the snow on the blades or flights. The snow is then dropped on the uppermost conveyor 83 of the superposed conveyor and as the snow is directed rearwardly by the conveyor, the snow will be acted upon directly by the flame throwers or projectors which will reduce the same to a liquid or semi-liquid condition. The snow is then depositedup on the uppermost par-- tition plate or platform 91 where the same is again acted upon by water from the pipes 107 which tends to reduce the snow to a liquid state. The snow is scraped off of the upon the intermediate partition plate or platform 91 where it is again acted upon by water sprayed from the pipes 107 The flights carried by the lower run of the intermediate conveyor 84 will propel the snow .or the like off of the plate and direct the same on the lowermost conveyor 85. The snow or slush is again directed toward the rear end of the machine where it falls on the lowermost platform or partition plate 91 when it is again scraped toward the front of the machine: When the snow is pushed to the forward end of the lowermost platform the same is dropped into the tank 82 where the same can be directed toward a gutter or sewer. The water in the tank 82 has its temperature effectively raised by the exhaust gases and other means heretofore described so that as the water leaves the tank the same will be prevented from freezing. In starting out with the improved machine the tank 82 may be partially filled with water if desired or necessary.

From the foregoing description it can be. seen that an improved snow removing machine has been provided, which will effectively scrape all snow from streets and road ways and reduce the same to' a liquid'condition whereby the samecan readily flow oh through the sewerage system of the city.
