To all whom it may 0001061 501:

Ben-known that I, J Aims LAGo nnsINo, a citizen of the Umted'StaJ-tes, l'fiSldlllg in Chicago, county of Cook, and State ol-Illinois', have inventedn certaininew and useful 3 Improvement in Snow Removers, of which the iiollowing is the specification. h

invention relates to thet elassiof devioeswwhieh are designed to remove the snow; from the streets without the necessity of uieiiiihhopetation other than is eflorded by the driis eiriof the machine. These devicesere suhj ot to the 5 greatest: {abuse-tend- Bough-neag' due to the oonditions u -den which they F opetriit hence; construct-1ons whieh would be satisfactory in: a 1 shop qu ckly become valueless in use;

My invention haSqfiQI' itsiohjeet to" providea 1 eonstruetion'whichwill survive" the rough est usage as well as ztbuse and still c'helusebleand .halsafor, its f-fhnthen' object to provide t e; deviee whiohfmay beQdetechebly secured to a truck, oijmey, if desired be constructed as -e11 integrall part of the truck, wanc't has for its further object to *provide means whereby the sno 'vendiee removed from the street may be -deposited-tupon other trucks so thetthewvork of the machine oanbeprae tically continuous.

upon a suitable axle 16 so as to sustain the weight easily. This axle is provided with a central pivot so that its direction may be shifted. The upper end 17 of the ladder is pivotally secured by means of roller -19 to beams 18 and 19 mounted upon the top of the truck 1 through the center of which the conveyor belt 7, which is supported by roller passes. Brackets 51 and 52 being formed on the forward end of the beams 18 and 19, in which are mounted the ends of the roller 49. Upon one end of this roller is mounted a sheave 50.

A wire cable 20 is provided to elevate the remover when not in use, the cable being secured to the lower end of the ladder, from which position it passes up over the sheave 50 and is wound upon a drum 21 indicated in Figure 2. The wheels 15 are guided by means of apair of wire cables 30 which are attached to the axle 16 and which pass over suitable sheaves (not shown) to the motor truck so that the direction of the remover may be shifted by the operator as the motor truck moves. An aperture 22 is provided in the shovel to receive a bolt to fasten it to the plate 25, so as to prevent its sliding movement when it is desired.

The 0 eration of the device is as follows: lVhen tie truck arrives at the place from which the snow is to be removed, the ladder is lowered into the position shown in Figure 1, through the medium of the wire cable 20, the drum 21 being unwound so as to let wheels 15 rest upon the ground.

These wheels are arranged so as to bring the point 14 of the shovel 8 practically in the same plane as the road bed which is to be cleared. The motor truck is then started and as it moves forward, obviously the point of the shovel is pushed under the snow which slides up over the surface of the shovel, striking the conveyor belt 7 on the ladder which carries it up to the top of the motor truck and along between the beams 18 and 19 to their overhanging ends at the rear of the truck. This extension permits the wagon or truck which is to be loaded to drive under the conveyor to be driven under the extension so the conveyor belt 7 will drop the snow into the empty vehicle without the necessity of the truck carrying the remover stopping at all.

Should the point 1 1 of the shovel strike any unevenness in the road, the springs 11 permit the shovel to slide inwardly, the slots 9 being provided for this purpose, the pins 10 preventing its moving too far. This movement permits it to jump any obstruction with comparative ease and even without the operator being aware of the unevenness.

Suitable gears are provided to be drivcn which in turn imparts its motion to the conveyor belt 7.

here there has been a hard storm and considerable ice is encountered, it is necessary to provide teeth on the shovel which is accomplished by a duplicate shovel which has a plurality of sharp teeth or point-s as clearly illustrated in the detail view, Fig. 5. lVhen the remover is provided with this form of shovel, it will successfully remove an accumulation of icy snow which the plain shovel would be unable to remove.

Having described my invention what I regard as new and desire to secure by Letters Patent of the United States is:

1. In a device of the character described, the combination of a pair of beams rigidly mounted upon the top of a self-propelled vehicle and extending longitudinally thereon, a ladder pivotally secured for vertical movement to the forward end of said beams, a plurality of rollers in said beams and ladder, a conveyor belt mounted upon said rollers, a plate of the same width as the ladder secured to the lower end thereof, shoulders on each edge of said plate which extend lon gitudinally its entire length, guides formed in said shoulders, a shovel slidably mounted upon said plate, having reinforcements along each edge which are fitted to and slide in said guides, there being slotted openings extending through said plate, adjacent its upper end, pins secured to the lower side of said shovel which extend through said slots, lugs formed on the lower side of said plate, springs which connect said lugs to said pins, whereby said shovel is held normally in a projected position.

2. In a device of the character described, the combination of a pair of beams rigidly mounted upon the top of a self-propelled vehicle and extending longitudinally thereon, a ladder pivotally secured for vertical movement to the forward end of said beams, a plurality of rollers in said beams and lad der, a conveyor belt mounted upon said rollers, a plate of the same width as the ladder secured to the lower end thereof, shoulders on each edge of said plate which extend longitudinally the entire length, guides formed in said shoulders, a shovel slidably mounted upon said plate, having reinforcements along each edge which are fitted to and slide in said guides, there being slotted openings ex tending through said plate, adjacent its upper end, pins secured to the lower side of said plate, sprmgs which connect said lugsv 'to said pins, whereby said shovel is held normally in a projected position, means carried by the fixed beams to elevate the ladder vertically.

In witness whereof, I have signed the foregoing specification.
