SNOW-REMOVING MACHINE.

Application filed July 30, 1923. Serial No. 654,757.

To all whom it may concern:

Be it known that I, MARSOP SoUHIoIAN, a subject of the Turkish Empire, residing at Lawrence, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Snow- Removing Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in street cleaning machines and relates more particularly to those designed for rapidly removing snow.

The object of the invention is to provide a comparatively simple machine of the class set forth which may be advantageously used upon the front of a motor truck to scrape the snow from the streets and dump it into the truck body to be carried to a suitable place for discharge.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description 7 being supplemented by the accompanying drawing:

Figure 1 is a top plan view of a machine constructed in accordance with my invention.

Fig. 2 is a side elevation.

Fig. 3 is a side elevation partlyin vertical section.

Fig. 4: is a partial side elevation looking in the opposite direction from Fig. 2.

Fig. 5 is a fragmentary plan view showing the arrangement which may be employed if the snow has packed and frozen upon the street.

In the drawings above briefly described, the numeral 1 designates the chassis frame of any desired form of motor truck, this truck being provided with a suitable dump body 2 and having a drivers cab 3 in front of said body. The front end of the chassis frame 1 carries a pair of horizontally spaced guides 4 for a pair of upstanding arms 5 which rise from a longitudinally disposed snow scoop 6, said arms being normally held in the guides 4 by set screws or the like 7. The scoop 6 is provided with a pair of caster wheels 8 having adjusting screws 9 equipped with hand wheels 10, whereby said scoop may be vertically adjusted to any desired height when the screws 7 are loosened. In the preferred form of constructlon, the bot- ..tom of the scoop 6 inclines rearwardly as indicated at 11, to a point near its rear end, the rear portion of said bottom however, being downwardly off-set to provide a depression 12 into which the snow is forced and from which it is elevated by an endless elevator 13. In the front portion ofthe scoop 6, I preferably mount a rotary beater 14 which feeds the snow rearwardly in said scoop and prevents it from piling up at said front end of the latter. Also, in order that a wider area may be cleaned at a single operation if desired, I prefer to provide a pair of extension plates 15 slidably contacting with the lower side of the bottom 11 and provided with upstanding side flanges 16. These plates are pivoted at 17 to the bottom 11 and may be swung outwardly when desired. For swinging theplates 15, I have shown bell cranks 15 fulcrumed on the sides of the scoop 6 and connected with the flanges 16 by links 18, said bell cranks being connected to rearwardly extending rods 19 leading to appropriate hand levers or the like 20 adjacent the drivers seat.

Mounted longitudinally upon the cab 3, is a trough 21 into which the snow is dropped by the elevator 13 and a rotary beater 22 extends across the rear end of said trough and operates in close proximity to the rearwardly declined bottom 23 of said trough and thus prevents accumulation of snow on said bottom and forces said snow to discharge into the dump body 2.

I prefer to drive the parts 13, 14 and 22 in the manner illustrated, from the rear axle 24 of the truck. At 25 I have indirated a drive chain for the axle 24, although other driving means could of course be employed. The axle 24 drives a transverse horizontal shaft 26, under the body 2, by means of a chain 27 and suitable sprocket wheels, or other desired means, and another transverse shaft 28 is provided in front of the shaft 26, the two shafts being rotatably supported by appropriate bearing plates 29, suitably mounted on the chassis frame 1. For driving shaft 28 from shaft 26, I have provided said shafts with spur gears 30 both of which mesh with another gear 31 slidably mounted on a suitable stub shaft 32, provision being made whereby said gear 31 may be shifted out of mesh with the gear 80 when the machine is to be thrown out of operation. In the construction shown, a bell crank 33 mounted on the frame 1, has pivotal connection with the hub of the gear 31 and a rod 33' extends forwardly from said bell crank to a hand lever 34: within reach of the driver.

Under the drivers seat, orat some other suitable location, I provide a transverse horizontal shaft 35 which is driven by a chain or the like 36 from the shaft 28. said shaft 35 being connected with the shaft of the rotary beater 14, by chains 37,. Gearin 38 at one end of the shaft 35 connects thls shaft with another transverse horizontal shaft 39 which is connected by a sprocket chain 40 with a transverse shaft 41 extending across the front end of the trough 21, said shaft 41 having sprockets 42 which drive the endless elevator 13, the lower end of this elevator being passed loosely around a roller 43 in the rear end of the scoop 6. The shaft ll is operatively connected with the shaft of the beater E22, by suitable gearing 44.

The construction so far described. will operate eifectively for cleaning comparatively loose snow from the streets, but if the snow has become packed and frozen, it is desirable to use the arrangement disclosed in Fig. 5. In this figure, I have shown a toothed plate bolted to and extending beyond the front end of the scoop 6 and instead of the rotary beater 14:, I make use of a driven shaft 51 having a plurality of spaced saws 52 with pointed pick teeth 53 between them. By employing this association of parts, the hard frozen snow, sleet or the like, may be effectively scraped from the street, broken up and then carried upwardly by the elevator 13. This elevator discharges into the trough 21 and the beater 22 forces the snow or the like rearwardly and distributes it into the body 2.

Whenever the machine is loaded the lever 34: may be operated to throw the gear 31 out of mesh with the gears 30, thus permitting the entire machine to be driven to a suitable dumping point.

As excellent results may be obtained from the details disclosed, these details may if desired be followed, but within'the scope of the invention as claimed, numerous minor changes may be made.

I claim 1. The combination with a motor truck having a drivers cab and a dump body in rear of said cab andextending to the rear end of the truck; of a trough-shaped snow scoo in front of and connected to said true a longitudinal trough. supported horizontally on top of said cab and extending from front to back thereof to discharge into the truck body, an. elevator in front of the cab from the rear end of the scoop bottom to the frontend of the trough, a rotary beater in the front end of the scoop above the bottom of said scoop and spaced rearwardl from the front end of said bottom for forcibly throwing the snow rearwardly to the elevator, and a rotary beater in the rear end of said trough for throwing the snow directly rearward into the truck body.
