tone, have invented certain new and useful Improvements in Street. and Highway Snow-Cleaning Machines; and I do declare the following to bee. ,full, clear, and exact description of the invention,- such as will. I enable others skilled in the art to which it appertains to make and use the same.

. This invention relates to the class of excavating, and more especially to those machines which include a plow and a carrier; of the same is to produce a snow-cleaning machine for use on streets on highways and by means of Which'the snow and ice will be scraped or plowedfroni the surface, carried upward, by a suitable 2o elevator, and then delivered at eitherside of the machine either back onto the street or highway or into a vehicle .which may he driven alongside. r

This and other objects'are carried out by 1'23 the constructionh'ereinafter more fully described and claimed, and as shown in the drawings wherein- ,Figurel is a. side elevation of my improved machine; Fig. 2 is .a plan view there- 89 f Fig. 3'is an enlarged transversesection taken on the line 3-3 of Fig. 1; F g. =1. an

iacl e; for han be possioleeespecially if another form of plow be era-- I make this statetion thereof may be indulged in without sacrificing the general principles involved. ile Ishowland do prefer a gasolene engine for driving the various belts, it is .ossible that some other motive power might e employed. Soalso with the means suggested below for propelling the entire machine, for whereas I have suggested that it might be driven by horse course possible that if the motor were large enough the horses could be omitted and power taken from the motor to propel the machine. On this understanding it will be clear thatninchoft-he following description and the corresponding illustration in the drawings, is given for faepurpose of setting forth the preferred vembodiment of my machine, rather than because the details shown and described are necessary to its successful operation. I

The vehicle or support illustrated in the drawings herewith. sled which is shown as comprising a main longitudinal beam '1 having a cross head 2 at its front end and runners at the extremities single runner 4- beingpivotally mounted as atv 5 beneath the rear end of the beam and pivotto steer the vehicle by In fact, if the vehicle be propelled by horse power it; may be steered by. directing the on the cross head 2 is almovable frame 7 which extends forwardof the foremost runners 3 or the foremost truckof the \"fiillClG and carries zit-its front corners two adjust able s11pports,2lieieiz1. shownas rulm'ers S which are. pivoted at one end as at 9 beneath the frame. and slotted in their. other ends as power, it is of of said head,

a Y e em-- at 10 to receive bolts 11 whereby they may be adjusted vertically to permit the forward end of the frame to approach nearer to the ground or to be raised above the same ac-.

cording as these runners are adjusted. The entire frame'rocks over the pivots or hinges 6, and its forward end is supported by'the runners 8; and the frontend of the frame carries a scraper or plow 12 by means which'the snow, ice, or other material'is taken ofi' of the surface of the ground or dug out f it. When the machine is being driven or propelled from point to point and it is not desired that this plow shall work,

the rear end'of the frame 7 is depressed onto the main beam 1 or other framework of'the .vehicle by anyv suitable mechanism, herein shown as a cable 1?,v which is led downward and around suitable pulleys 14 whence it passes to the rear and is carried over a windlass 15 which stands adjacent the'drivers seat 16, the latter being supported by a framework- 17 rising from the rear end of the beam 1. When this Windlass vis turned in the proper direction to wind up on the cable 13, the rear end of the frame is depressed and its forward end is raised so that I the runners 8 no longer contact with the ground and the plow 12- is lifted entirely out of engagement therewith. On the other hand, when the tension on the cable is relaxed, the plow drops into working positionas'shown in Fig. 1.

. The elevating'mechanism is carried by the f rocking frame 7 and it comprises a trough,

and an elevator and presser moving upward therethrough. Beams 20 are secured at their lower ends to the frame 7 and are mounted at their rearupper ends on standards 21 rising from the same frame 7 and the trough consists of a floor 24 and sides 22 carried y said beams; At points near. their upper l lower ends said sides are provided with artshaped slots 23 for a purpose yetto appear.

The elevator is of the ordinary endless type, comprising-chains 25 at each side cong,

' vnected by. suitable slats 26which pass over ,.the floor -24 of the trough the chains, running over-sprocket wheels 27 and 28 at the extremities of the elevator as usual and the return or lower side of; this endless belt run-.

ning downward'beneath' the trough floor asv seen inFig. 1. v vator and is in'efiect anotherendless carrier mounted in a frame 30 of it's-own, the frame being of a v proper' size to fit movably be. tween the sides 22 of'the trough and by prefv erence havingan extension 31 hingedly' connected to its front end by a rule joint 32 so that the extension projects forwardly and: downwardly beyond thefront end of the ele-. vator, whereas the rearend of-the'frame 30" is not carried upward as far. as the frame ofsaid elevator. The endless carrier form ing part of the presser is composed of a pair The presser overlies the eleof chains 35 connected by slats 36, the moving around sprocket wheels 37' and 38 'Whose shafts are journaled in the frame 30 at its upper end and in the extension-31 at 1 its lower end, and theslats are provided with spurs 33 or brushes 34 or both for a purpose to appear. a 4

The motive power for actuating the eleating mechanism is herein shownas 'a' gasolene engine E whose controls are within reach of the operator sittingonthe seat 16 and need not be described; and power from saldmotor is conveyed in any suitablemanner to a shaft 40 which is journaled through i the frame 20 'of the trough and carries at so each end a pair of sprocket- wheels 41 and 42. Each sp-rocket wheel 41 is connected by a chain belt 43 with a sprocket 44 fastion" i the upper shaft 49 of the presser, and each Y sprocket wheel 42 on the shaft-40 is connected by 'a twisted belt 45 with a.'sprocket wheel 46 fast on the upper shaft of'the ele- 0 va tor. Therefore when power is conveyed from the motor E through suitable clutches or other connections to the shaft 40,; the '90 sprocket wheels 41 and 42 thereon drive thevelevator and the presser in the proper direction to cause their adjacent sides to move p r y in parallelism and preferabl the same speed" h pper shaft 49 of the presser gasses through a slot 50 in afbracket 51 sim within an at each side of the trough. The

The 'elevatingmechanism carries the material upward and drops it over the rear shaft thereof onto the delivery mechanism which, as above described, may beset to deliver the material to eitherside of the machine and from it. Meanwhile the direction and'sped or rotation of the shaft 84 may be controlled by the driver, and if he throw out the clutch the elevator and delivery mechanisms will come to rest. When the entire machine is to be driven to the point where work is to be done, o'rback down on the rear end of the-rocking frame 7, and the front end of the machine. is "lifted off the ground. In fact, this adjustment might be used to cause the tip of the plow to sta'nd nearer to or to the shed, the Windlass is turned -so that I the cable 13' draws more remote from the earths surface, or

possibly to embed the same if the machine were used for scraping up dirt, or in other ways well understood by those familiar with this art.
