- This invention relatesto snow plows, and particularly to the construction of the V or nose thereon Although 'not specifically 1 limited to such use, our invention is especially 5 effective with truck-propelled plows, andin the further discussion thereof herein, we shall refer to it asapplied to a truck plow; It will be understood, however, that this treatment r is purely illustrative'and in no way limiting. Snow conditions in truck plowing as in all other kinds of truck plowing are extremely variable. a a I f l Two specific conditions constantly being c c met in truck plowing'a-re not only'variable but opposing in their requirements for plow design. 'When plowing moderate 'depths of snow at'speed, the object of the truck plow is to throw the snow as far as possible oifthe road in order that it may neither have to be handled again not: make side banks which tend to cause re-driftingand blocking-of the road." 'j
The truck plow which would most efficient- .7 ly'throwrthe snow off the road'would be constructed with a sharp outward overhang at the top of the V softhat as the loose snow is forced upward by the speed ofthe V it strikes 1 this overhang and is shot out to one side with l i great velocity. But through accident, neglector for many other reasons snow may have accumulated, settled and frozen in great depth before the truck plow starts to move it or in which case the sharp outward overhang, which would make the most efi'ective snow throwingspeed plow, cramps the deep heavy snow and makes it difiicult for the truck plow to penetrate. V
1 For such a condition of deep heavy snow a plow without the sharp outward overhang would be more efiicient and would penetrate the drifts where the speed plow would cramp because the absence of sharp outward overhang would permit the deep heavy snow to roll up past the top of the V as in a tractor snow. 7
The result in prevalent snow plow deslgn has been to enforce a compromise design;
plow which is primarily designed for deep drifts because the logical design for the one design for the other, and because efliciency in the one field constitutes deficiency in the other field. Heret'ofore the practical plows have'sacrificed some of the qualitiesnecessary to efficiency under" each condition in order to; copemoderately well with both. I 7
7 Purpose is opposing in principle to the'logical To'the end therefore of provlding. a snow iv plow which will be capable of operating with complete eflicienc-y regardless of which of these two snow. conditions are met, we have and having its surface formed as'a continuation of the surface curve of the main portion of the mouldboard. The snow rolling Vip ortion is designed to lift and roll the snow higher than itself being efficient for heavy snow'conditions, deep hard drifts and in general for heavy duty work wherethe depthor, resistance of the snow reduces the speed and causes the propelling-"truckby reason .of reduced speed to function similarly to atracto r.
The snow-rolling V should be specifically vdesigned for, penetrating snow depths greater than the height of the V without cramping, and to avoid cramping, in deep snows must have only a" small amountof outward overhangatthe top so that the snow can roll smoothly upward in" a direction" approximating the vertical and so lift and pile the snow removed on the top of the banks higher than the V.
