The present invention relates to new and useful improvements in terracing machines, and has for its primary object to provide, in a manner as hereinafter set forth, a device of this character which is adapted to be expeditiously attached to the rear end of a conventional tractor for operation.
Another very important object of the invention is to provide a terracing machine of the aforementioned character which embodies unique means for adjustably supporting an earth working or moving blade.
Still another very important object of the invention is to provide a machine of the character described which, if desired, may be conveniently used for ditching, leveling, et cetera.
Other objects of the invention are to provide a terracing machine which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact, light in weight, and which may be manufactured at low cost.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a top plan plan view of a machine constructed in accordance with the present invention connected to the rear end of a tractor.
Figure 2 is a view in side elevation of one of the supporting wheels and its suspension means.
Figure 3 is a cross sectional view through a portion of one of the supporting wheels, taken substantially on the line 3-3 of Figure 2.
Figure 4 is a view in rear elevation of the blade and adjacent parts.
Figure 5 is a top plan view of the blade.
Figure 6 is a cross sectional view, taken substantially on the line 6-6 of Figure 4.
Figure '7 is a view in side elevation of the diagonally mounted blade, showing the extension on one end of said blade in cross section.
Figure 8 is a cross sectional view, taken substantially on the line 8-8 of Figure 4.
Figure 9 is a fragmentary view in horizontal section, taken substantially on the line 9-9 of Figure 8.
Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a metallic bar I which is square in cross section. The bar l is connected transversely to the rear end of a conventional tractor 2 through the medium of beams 3. Suitable braces 4 are provided for the beams 3.
Rotatably mounted beneath the bar I are crank axles 5. The'crank axles 5 carry supporting wheels 6 of the type comprising substantially V-shaped rims 1. Hand levers 8 are mounted on the bar I and operatively connected to the crank axle 5 for raising and lowering the supporting wheels 6.
Beams I4 and I5 are rigidly clamped on the bar I at spaced points and extend forwardly and rearwardly therefrom. Mounted on the beams I4 and I5 is a diagonally extending mold board [6. An angular extension I1 is mounted on the rear or trailing end of the mold board [6. Removably mounted on the lower portion of the mold board I6 is a removable blade [8. The forward end portion of the blade [8 has secured thereon a point ii) of substantially the construction shown to advantage in Figure 7 of the drawings. Mounted on top of the mold board I6 is a forwardly inclined guard or fender 20 which prevents dirt from passing over the top of said mold board.
Mounted on the upper portion of the back of the mold board l6 are metallic straps or loops 2!. An angle iron bar 22 is mounted on the lower portion of the back of the mold board I6. Adjustably mounted on the bar 22 and extending rearwardly therefrom are pins 23 which are adapted for swinging movement in a horizontal plane. Yokes 24 and 25 are journaled on the pins 23. The yokes 24 and 25 receive therebetween the lower portions of the beams l4 and i5. As best seen in Figure 6 of the drawings, the legs of the yoke 24 are formed to provide apertured extensions 26 t facilitate adjustment on the beam l4. Hooks 21 are secured in the upper portions of the yokes 24 and 25 and engaged in the loops 2| for connecting the upper portion of the mold board l6 to the beams l4 and I5. Bolts 28 adjustably secure the assembly comprising the elements I4, I5, 24, 25, 21, et cetera.
It is thought that the operation of the machine will be readily apparent from a consideration of the foregoing. Of course, the diagonally extending mold board I 6, with the blade I8 thereon, is moved over the ground by the tractor 2. Through the medium of the hand levers 8 the mold board IB may be expeditiously raised, lowered or adjustably inclined as desired. The mounting of the mold board IS on the beams I4 and I5 has sufi'icient play or looseness to permit the desired adjustment. Tilting of the bar I is permitted by the looseness and flexing of the tractor connecting frame. By reversing the beam I4 on the bar I to parallel the beam I5, the mold board l4 may be mounted transversely for performing other kinds of work. When this is done the adjacent supporting Wheel 6 with its suspension or attaching means is moved outwardly on the bar I to accommodate the mold board IS in a transverse position.
It is believed that the many advantages of a terracing machine constructed in accordance with the present invention will be readily understood, and although a preferred embodiment is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
What is claimed is:
A terracing machine of the character described comprising a wheel supported bar, means for connecting said bar to a source of power, beams mounted on the bar, a 'mold board, a blade mounted on said mold board, loops mounted on the back of the mold board, a bar mounted on the back of the mold board, pins pivotally mounted on the second-named bar, yokes journaled on said pins, said yokes straddling the beams and being secured thereto, hooks on the upper portions of the yokes engaged in the loops, and a forwardly inclined guard on the upper portion of the mold board.
