Application June ,12, 1947,, Serial vlilo. 75.4 296 This invention relates to'earth moving equipment and more particularly to "terracing and ditching attachments for tractors.
'The principal object of the invention is -to pro vide an earth moving blade and a mounting therefor, the latter being ,so designed and constructed that its attachment to a tractor may be accomplished quickly and with little effort and in addition to the provision of a semi-circular subframe supporting the "blade -for angular adjustment on a horizontal plane with respect to the longitudinal axis of the main frame, the latter is provided with a swivel joint intermediate its ends which permit the blade to be adjusted to a varietyo'f angles in a'vertical plane.
Another object of the inventionjis to jprov'idea terracing and ditching attachment for tractors in which the blade carrying main frameiis pivoted for vertical displacement at its rear end to :raise and lower .the blade, such movement ,lbeing accomplished through the medium of the power lift mechanism of the tractor.
Still another object of the invention is to provide a terracing and ditching attachment for a tractor in which means is provided for not only predetermining the depth of penetration of the blade but also for sustaining the same in adjusted angular position in a vertical plane.
With the foregoing objects in View, the invention has further reference to certain features of accomplishment which will become apparent as the description proceeds, taken in connection with the accompanying drawings wherein:
Figure 1 is a front perspective view of a tractor showing the invention mounted thereon.
Figure 2 is a perspective view of the invention, per se.
Figure 3 is a fragmentary view of the tractor of Fig. l on an enlarged scale, showing a side elevational view of the invention.
Figure 4 is a perspective detail view of the side torque limiting and adjusting frame.
Figure 5 is a fragmentary perspective view of the main frame and the blade carrying sub-frame, together with the means for holding the latter in adjusted position, and
Figure 6 is a schematic view showing one position of the blade in the soil.
Continuing with a more detailed description of the drawing, reference numeral 10 generally denotes a tractor equipped with the conventional power lift mechanism which includes a transverse shaft I i, on each end of which is an arm l2.
The main frame of the invention consists of a substantially V-shaped, horizontally disposed member l3 constituting the rear section and to arrangement provides adjustment in the angle or tilt of the earth moving blade to be later identified. To the ends of the beams 14 are attached "the legs of a yoke t5, the inwardly convergent ends 0f the members forming the yoke embracing a partlii of alswive'l .17. The beams I4 and jyoke i5 constitute the front section of the frame.
"Tension arms T8 are connected to the swivel I! and extend ,aneularly upward and are secured to theiunderside of the tractor, asshown. Companion bracing arms 1'9 depend from the tractor and support the swivel I! from each side thereof. A transverse rod 20 maintains spaced relationship of the ends of 'the'beams I' l at their points of junction with the legs of the :yoke 1 5.
Secured rigidly to the vertex of the V-shaped member l3 and extending forwardly between the legs thereof is a channel member 2|. The web of this member extends beyond the flanges thereof at its front end to form a tongue 22 (Figure 5). The tongue 22 lies under and supports an arcuate or semi-circular sub-frame 23 formed preferably of angle iron, the horizontal flange 24 of which is provided with a plurality of equidistantly spaced holes 25. To the ends of the sub-frame 23 are attached brackets 26, the latter, in turn, supporting a blade 21 having an interchangeable or replaceable cutting edge 28. A king pin 29 passing vertically through the vertex of the member [3, and the end of member 2|, serves as the pivot for the blade 21.
Secured to the tongue 22 of member 2| by bolts 30 is a bracket 3| under which the arcuate subframe 23 slides. A rod or pin 32 is passed vertically through a hole in this bracket and enters a hole 25 in the sub-frame,. selectively aligned therewith. The arrangement holds the blade 21 in adjusted angular positions in relation to the longitudinal axis of the main frame.
The rear portion of the frame is suspended by chains 33, one on each side, the lower ends being attached to the beams l4 near the rear ends thereof. The upper ends of these chains are adjustably attached to hooks 34 (Figure 3) on the shaft I I. By changing links of the chains on the hooks 34 on one side or the other, the angle of the blade 21. is altered ina vertical plane and its depth of penetration may be predetermined in the same manner.
It is apparent from the foregoing that the blade is attached the lower end of a chain 36, the up-;
per ends of the chains being adjustably attached to the ends of the arms l2 of the power life mechanism. When the frame is raised and lowered by actuating the power lift mechanism, it pivots on a pin 31, from which point the forward end of the frame is suspended from the tractor by the members H3 and I9, as described.
In order to limit side movement of the blade 21 in operation, a vertical frame 38 (Figure 4,)
mounted on the transverse angle iron 35. The top member of the frame 38 has therein a series of longitudinally aligned holes 39 which are in register with an equal number of holes 40 in the transverse member 35 therebelow and parallel therewith. A pair of rods 4| pass through the holes 39 and 40 from member 38 to member 35 and are replaceable in companion holes. An angular arm 42 (Figure 3) is pivoted for vertical swinging movement to a mounting 43, attached to the tractor and extends downwardly and rearwardly to lie between the vertically disposed and parallel rods 4|. The obvious result is that the degree of side draft of the rear portion of the frame is determined by the relative spacing of the rods 4| since these rods come up against the arm 42 and are restricted thereby against further displacement.
Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claim is also considered to be within the spirit and intent of the invention. What is claimed is: In an earth movin attachment for a tractor, a main frame supported under and attached to said tractor for angular movement about a horizontal axis and having on its rear end a substantially V-shaped member, a blade having its pivot at the vertex of said member for adjustment to a variety of angles on a horizontal plane in relation to the longitudinal axis of said main frame, an arcuate sub-frame oscillatable below and supported by said main frame, the ends of the sub-frame being attached to the ends of said blade, means for adjusting the depth of penetration of said blade, a vertical frame on the main frame having horizontally parallel members, one being provided with apertures in register with apertures in the companion member, vertical rods interchangeably disposed in said apertures in relative parallelism, and means pivoted for vertical movement on said tractor and extending between and engageable with said rods to limit side draft of said main frame.
