Figure 7 is a rear view of the modified form shown in Figure 6;

Figure 8 is a top plan view of the modified form of the invention;

Figure 9 is an enlarged fragmentary longitudinal vertical section, taken substantially on the plane of line 9-9 of Figure 8, looking in the direction indicated by the arrows; and

Figure 10 is a fragmentary detail view of the special slidable hinge connection employed between each of the transversely slidable bars and the rear side scraper blades.

Referring more in detail to the drawings, it will be noted that a substantially U-shape supporting bracket H is secured in the forward end of the frame or chassis l2 of a motor truck or the like by bolts 3 or other appropriate means, The main portion of the bracket II is offset downwardly and converges toward its forward end or bight portion l4 which extends at a sharp angle to the angle to the legs or sides of the bracket The bracket extends for some distance pass the forward end of the truckframe or chassis I2 and has a transverse bar |5 mounted on'its forward portion and provided centrally with a pair of upstanding lugs l6 supporting therein the fulcrum bolt l! for a pair of bell crank levers I8 and I9. These bell crank levers 8 and H] are employed for raising andlowering. or tilting the substantially V-shape front shoe 20 having the special forward scraper blades 2| secured on its lower edge by bolts 22 or the like, recesses 23 being provided in the forward face of the front shoe 20 at its lower edge to receive the upper edges of said front scrapers 2| so that the outer faces of the front scrapers 2| are flush with outer face of the front shoe 20. These front scrapersZl naturally converge and meet at their forward ends. Both of the front scrapers 2| are curved from their upper edges to their lower edges to present concave 'outer faces and convex inner or rear faces. A

scraper .blade 24 is removably mounted on the forward face of each front scraper 2| at the lower edge thereof by bolts 25 or other appropriate means, the scraper blades 24 being curved slightly from their upper edges to their lower edges corresponding to the curve of the front scrapers 2|.

The scraper blades 24 furthermore, have their lower cutting edges 26 bevelled or inclined rearwardly so that the scraper blades 24 may have sharp lower edges to effectively cut away ridges and the like on the road bed. The curved or arcuate lower arm 21 of the bell crank lever I8 is bifurcated and has its branches loosely connected as by means of link connections 28 with the rear transverse bar 29 connecting the diverging branches of the front shoe 20, beneath the bracket The long upstanding arm 30 of the bell crank lever I8 is pivotally connected with an actuating which extends rearwardly over the engine casing. 32 of the motor truck and into the body or cab 33 thereof, a hand grip 34 being provided on the free rear extremity of the bar lever 3| by means of which the operator may readily actuate the bar lever 3| and set the same 'in adjusted position by'catching the proper rack teeth 35 on the underface of the bar lever 3| in the plate 36 through which th bar 3| operates,

within the motor truck body or cab 33. The

lower arcuate arm 3'! of the bell' crank lever I9 is likewise loosely connected by a link connection 58 or the like with the forward transverse bar 39 connecting the branches of the front shoe 20 be- -56 have slidable thereon the collars low and forwardly of the bracket H. The long upstanding arm 40 of the bell crank lever l9 is pivotally connected to the forward lower end of the bar lever 4| for controlling the same and which projects into the body or cab 33 of the motor truck with an appropriate hand grip 42 on its rear end by means of which the operator may readily actuate the bar lever 4|. This bar lever 4| also has rack teeth 43 on its lower face adjacent its rear end for locking engagement with the plate 44 in the motor truck body or cab 33 and through which the bar lever 4| extends. It is apparent that by actuation of the bar levers 3| and 4|, the forward end or the rear end of the front shoe 20 and parts carried thereby may be tilted as desired or by actuation of the bar levers 3| and 4| together, the front shoe 26 and parts carried thereby may be raised or lowered vertically. During raising and lowering of the front shoe 20 and parts carried thereby, the angular guides 45 carried on the inner face of the shoe 20 at opposite sides thereof serve to guide the shoe 20 with friction reduced to the minimum, as the angular guide bars 45 are located opposite the forward corners of the bracket l l.

Mounted transversely beneath the frame or chassis I2 at the centre thereof or just rearwardly of the centre, is a rear scraper supporting bar 46 having a pair of straps 47 mounted on its opposite ends and projecting slightly from the sides of the motor truck chassis |2 and supporting upstanding hinge pins 48 on which are mounted the hinge plates 49 of the pair of diverging rear scrapers 50, the hinge plates 49 being secured on the rear or inner faces of the rear side scrapers 50 and projecting from the forward ends thereof. The hinge plates 49 are of arcuate form with collars 5| on their projecting upper and lower ends and which collars 5| are loosely mounted on the upper and lower portions of the respective upstanding hinge pins 48. It will thus be seen that the rear side scrapers 56 may be adjusted vertically on the hinge pins 48 and retained in their vertically adjusted position by small collars 52 positioned on the hinge pins 48 below the lower collars 5| and secured in their adjusted positions vertically of the hinge pins 48 by securing pins 53 or the like passed through the collars 52 and through the selected openings of a series of spaced openings 54 extended transversely through the lower portions of the upstanding hinge pins 48. The rear side scrapers 54 are straight from their upper edges to their lower edges with scraper blades 55 secured on their lower edges and curved outwardly therefrom with the bottom edges of said scraper blades 55 bevelled on their under faces so as to present sharp lower edges which will effectively cut away ridges or the like on the sides of the road bed. Upstanding vertical hinge bars 56 are provided on the inner faces or rear faces of the rear side scrapers 58 just forwardly of the centre thereof. These hinge bars 5? provided at the outer ends of hinge plates 58 which are hingedly mounted on the rear faces of a pair of transversely movable rack bars 59 sliding through guide loops 60 on a supporting plate 6| mounted transversely on the rear portion of the motor truck chassis l2, rack teeth 62 being provided on the forward faces of the rack bars 59 from their overlapping inner ends for the greater portion of the length of said rack bars 59. The rack bars 5!! are operated together to force the rear side scrapers 5|) outwardly from one another or draw them inwardly toward one another on the upstanding'hinge pins 48, by means of a'pinion 63 positioned between said rack teeth 82 thereof, said pinion 63 being carried on the upper end of a stub shaft 64 rotatable through the plate 6| and through a bearing 65 positioned beneath said plate 6|. A bevelled gear 88 is carried on the lower end of the stub shaft'64 and operated by a bevel gear 61 meshing therewith and carried on one end of an operating shaft 68 which in turn is carried inappropriate bearings 69- swung beneath the motor truck chassis I2, the shaft 68 extending rearwardly and projecting from the rear end of the chassis I2 with an actuating crank 18' on its rear extremity. To looktheshaft 68 against unauthorized rotation and thus maintain the rear side scrapers 58 in set adjustment, a ratchet wheel H is rigidly mounted on the shaft 58 and normally engaged by a double reversible-pawl 12 having its arms or branches directed at right angles and the free ends 13 thereof slightly turned or bent in opposite directions for positive looking with the teethor the ratchet wheel 1I, said double reversible pawl 12. being mounted at its centre ona fulcrum member 14 carried on the rear of the chassis I2. To reduce friction to the minimum during adjustment of the rear side scrapers 58, a pair of grooved antifriction rollers or idlers 15 are mounted on the plate 61 with their peripheries engaged against the outer faces of the respective rack bars 59. The rear side scrapers 58 are brought in close to the sides of the motor truck chassis l2, inwardly of the free rear ends of the diverging branches of the front shoe 2!) and the front scraper blades 24 carried thereby so as to catch all snow and ice and the like cut from the surface and thrown out by the front scraper blades 24. Furthermore, the rear side scrapers 28 are of considerable length, thus permitting proper adjustment of the same to assure cutting away of ridges'and the like from the centre of the road bed to the outer side edges of the road or as near to the same as desired.

As the construction of the device has thus been described in detail,-b'rief reference is now had to its use and modus operandi: The front shoe 28 and parts carried thereby are raised and lowered or tilted either forwardly or rearwardly asdesired, by proper manipulation of the bar levers 3| and M by the operator while still in his position within the body or cab 33of the motor truck. Adjustment of the rear side scrapers 58-and the scraper blades 55 carried thereby is accomplished, however, when the snow plow is stationary. The rear side scrapers 58 may be readily raised or lowered on the hinge pins 48 and the collars 52 secured in adjusted position below the lowermost collars thus assuring retension of the rear side scrapers 58 and blades 55 in vertically adjusted position. The shaft 68 may be readily manipulated by the crank 18 for swinging the rear side scrapers 58 outwardly and inwardly on the hinge pins 48 when the pawl 12 is thrown on its fulcrum member 14 to inoperative or non-functioning position.

In the modified form shown in Figures'fi to inclusive, the machine includes a body 16 having side runners 11 supported along the sides thereof by transverse beams 18 extended beneath the body 16 and connected at their opposite ends with the inner sides of the runners 11. An additional brace bar 19 is extended across the forward portions of the side runners 11 outwardly of the forward end of the body 16 to further brace and strengthen the side runners 11. A tongue carrymg bar 88 is extended across the front of the side runners I2 and rotatable in bearings 8! carried on said runners 11. .A draft tongue 82 has its rear end secured to the centre of the bar 88 and the draft tongue 82 is braced by angularly'ex t'ended brace'bars 83 which have their rear ends turned and secured to the bar 88 by'appropriate fastening means, while theforward ends of the brace bars 83 are also turned and secured on opposite sides of the draft tongue 82byappropriate fastening means 85.

The forwardly converging front scraper blades '86 have their forward ends meeting and firmly fastened together and the upwardly curved front shoe 81 is secured to the connected forward ends of the front scraper blades 86. The shoe 81 is preferably formed of a metal bent upon itself with the lower end 88 of the material secured beneath the connected ends of the front scraper blades 86-, while the other end 89 of the front shoe material is extended upwardly and then bent down over the scraper blade supporting plates 98 on which the blades 86 are carried, said end 89 being bent around and secured on a transverse pin 89a extending through the plates 98. In order that the front scraper blades 86 may be readily raised and lowered or tilted to the desired incline, the plates 98 are loosely connected to the forward ends of the side runners 11 by slide hinges 9i. These plates 98 are connected-by a transverse connecting bar 92, forwardly of the body 16 and the side runners 11 and a pair of rearwardly converging bar levers 93 have their forward ends hinged to the bar 92, near the ends of the latter. These bar levers 93 extend over and rock on the transverse-bar 19, beneath the bar 88. Owing to the main portion of the bar 88 being raised or offset upwardly, the bar levers 93 may be operated without interference by the bar 88.

Each side runner 11 has at its centre a longitudinally elongated vertical slot 94 which has its forward and rear walls inclined so that the top of the slots 94 are longer than the bottom thereof. Working in each slot 94 is a wide knife 95 having its lower end 96 bevelled and slightly turned forward. Each knife 95 is adjustable vertically within its respective slot 94 and is' slidable through a loop guide 91 carried on the inwardly offset end 99 of a U-plate 98 supported in the slot 94 by means of a bolt I88 extended transversely through the centre of the slotted portion of the side runner 11, near the upper edge thereof. The knives 95are each raised and lowered in their respective slots 94 and thus ad justed to the proper height within the side runners 11, by means of a slightly curved finger I8I provided on the bevelled'forward end I82 of a Each lever lever I83, by bifurcating the same. I83 is carried on a fulcrumed member I84 extended transversely through an upstanding bracket I85 on the side runner 11 for which the knife 95 is provided. Each lever I83 is then extended upwardly and carries a conventional spring latch I86 for automatic locking engagement with the segmental rack I81 positioned adjacent the lever I83, so that. the latter may be readily locked in adjusted position. When either lever I83 is to be re-adjusted for raising or lowering the knife 95 controlled thereby, the lever 183 may be readily released from the segmental rack I81 by theconventional releasing finger I88 provided for this purpose on the lever I83. It

WiIL'thBIBfOIB, be apparent that the knives 95 may be independently adjusted and as the levers with the planes parallel to one another.

other bar H3 slides.

I 03 converge towardone another, as they are extended upwardly and rearwardly, they may be readily operated by the attendant on the body 16, the same as the levers 93 which are forwardly of the levers I63. Hoods I89 are positioned over the slots 94 and extended outwardly over the sides of the body 16, to discharge to the sides of the machine, the material cut by the blades and rising in the slots 94.

The pair of rear side scraper blades H0 are carried on the guide wings III which are hinged at their forward ends to the outer faces of the side runners i1, rearwardly of the centres of the latter, by appropriate hinges H2. The wings H i diverge real-wardly and the transversely sliding supporting bars H3 for the wings III have their outer ends connected to the inner faces of the wings ill at about the centre thereof, by the loose hinges I M, straps l I la of which are hinged on the respective bars H3. Supporting bars H3 slide transversely across the rear portion of the sleigh body 18 with their inner ends overlapping, owing to positioning of one of the bars H3 in a plane slightly forwardly of the other Each of the bars H3 carries a loop guide H5 projecting laterally therefrom and through which the Both of the bars H3, at their overlapped portions are adjustable through a larger loop guide H6 formed by offsetting upwardly a portion of the strap H1 secured longitudinally on the body E6, so that the bars H3 may be readily adjusted transversely of the body 76 to regulate independently the angle of each of these Wings Hi and the rear scraper blade H0 carried thereby. A set screw H8 or other means is employed for securing the bars H3 in adjusted position in the loop I [6.

As the construction of this modified form has now been fully described, brief reference is now had to the use and modus operandi thereof: It is to be noted that the snow, plow could be drawn by any appropriate power connected with the tongue 82. The body 76 of the machine is firmly supported on the side runners T! which ride on the road bed and permit adjustment of the front scraper blades 86; the knives 35 and the rear scraper blades H5, independently, by the attendant on the body '55. The rear scraper blades H8 continue the scraping work of the forward front scraper blades 86 and serve to throw the loosened material to either side of the road bed.

At the same time, the knives 95 may be employed for cutting away ridges or projections on the road surface such as the side walls of ruts, formed by the wheels of motor vehicles, wagons or the like, so as to present a smooth surface the entire width of the road bed. These knives 95 may be readily adjusted to correspond or independently of one another, by separate adjustments of the levers I93 for the respective knives 95. All of the adjustments may be readily effected by the attendant while positioned on the body 16 of the snow plow and the adjustment may be made without interferring with proper functioning of the side runners T! or the connection of the snow plow with its draft means.

From the foregoing description taken in connection with the accompanying drawings, it will be manifest that'a combination snow plow is provided that will fulfill all thenecessary requirements of such a device, but as many changes could be made in the above description, and many apparently widely different embodiments of my invention'may be constructed within the scope of the appended claims without departing from the spirit or scope thereof, it is intended that all matters contained in the said accompanying specification and drawings, shall be interpreted as illustrative and not in a limitative or restrictive sense.
