Near the rear endof the machine we elements composed of members 26 and 27,
levelingv and deflecting 1 V the like, extending through said hinge members and interlocking members on the ends of member 26, as-at 29, shown in Fig. 7. It will be observed the member 27 is substantially shorter than member 26 and adapted to. be hingedly connected thereto by means of the member 31 on the end of mem ber 27. The outer end of member 27 is similarly connected to the inner side of runner 2.by means of members 32 and Members 26 and; 27 are held inalinement diagonally of the machine between the runners 1 and 2 by means of a brace rod 34, having itsendsbent downwardly andinserted in the hinge members 29 and 31 and v in themember 27 on runner 2. 'VVhen used as .aleveler, the :member 27 is adapted to be removed altogether and the free end, of
At the front end of the machine, we provide a gradingelement 35 having ametal cuttinglblade 36 on the front side thereof.
Said grading means-is adapted to float betweenthe runners 1 and 2 and a draft con- I nection is provided therefor by means of a with the grading element by means of rods chain 37 which extends transversely of the machine and through eye bolts or eye bars 38,38, attached to thef-ront ends of the runners land 2 and adaptedto be connected 39 and 40 near opposite ends of member 35.
Saidrods may have hooks on their forward ends for connection v with the chain37 and their rear ends are bent downwardly throughsoc kets 41 on members '41 attached to the rear side of member 35. Thus, the bent portion of said rods will serveto hold the member 35 vertically positioned at all times and the chain 37 with which said rods are connected may also serve as a main draft chain to which a team of horses may be hitched for moving the machine over the surface ofthe ground-to be -graded or leveled. The angle of the grading element may be adjusted more evenly and to better advantage by the use of a chain, as at 37, than otherwise and longer rods may be used for connection with the chain when it is desired to position the member 35 transversely, or nearly so, of the machine, as shown in broken lines in Fig. 2.
The depth of the cut to :be made by the member35 is adaptedto be regulated by foot pressure by means of a pair of parallel bars 42 and 43 attached pivotally .to the upper side of said member, connected together at their rear ends by. means of a transverse member 44 and having .a-fulcrumon the adjusting the ends of said member to the depth of the cut made by member 35.
edge of transverse member 6 of the machine frame. When the o aerating angle of member 35 is established, the member 44 is held at right angles to the runners l and 2 by members 42 and 43, a plurality of bolt holes 45 being provided for this purpose, and it I will be obvious that when the rear ends of members 42, 43 are depressed by foot pressure on member 44, the member 35 will be correspondingly elevated.
Our machine may be also used as a field leveler or grader with equal results. As a leveler for field use only, the member 35 may be removed and the member 26 used in the position shown in full lines in Fig. 5, where a rigidly held leveling member will suffice. But in the event such will not suffice, then the same results may be accomplished with the floating leveler 35 held in the position shown in broken lines in Fig. 2.
In the latter case it will be desirable to elevate both pairs of runners, so that the dirt will be discharged at both sides of the machine. It will be also understood that the machine will serve as a drag and stones and the like will be also removed from the road or field thereby with satisfactory results.
It will be understood that we have shown only one preferred form of structure and details of our machine, and we do not desire to limit ourselves to any specific structure or form of device, for we may substantially modify the same without departing from lib the spirit or enlarging the scope of our invention, except as we may be limited .by the apggnded claims.
