BRIEF DESCRIPTION OF THE DRAWINGS
In the accompanying drawings, which illustrate exemplary embodiments of the present invention:
Figure 1 is a side elevation of an apparatus for installlng a barrier;
Figure 2 is plan view of the apparatus for Fi~ure 1:
Figure 3 is an isometric view of one form of barrler; and Flgure 4 is an isometric view of an alternative form of barrier.
DETAILED DESCRIPTION
Referring the accompanying drawings, and espec-ially to Figures 1 and 2, there is illustrated an appar-atus 10 for installing a barrier. The apparatus includes a rectangular frame 12 supported on two wheels 14 at the front and two wheels 16 at the back. The wheels at the front are widely spaced, ~ust outside of the frame, while the two wheels at the back are closer to one 13049~7S
another so that they can serve as furrow packing wheels, as will be described in the following. At the front of the frame is a 3-point hitch 18 that is used for drawing the apparatus across a ground surface.
Two plow discs 20 are mounted on the frame by struts 22 projecting downwardly from a frame cross member 24. The struts are supported by braces 26 extending from the struts upwardly and to the rear to join a second frame cross member 28. The two plow discs diverge to-wards the rear of the frame, so that as the apparatus is drawn across a ground surface the dlscs open parallel furrow~, llfting the ~round ln opposite dlrections.
Immedlately behind the plow discs 20 is a barrier material supply. This is a roll of flexible material mounted on a transverse shaft 34 in bearings 36.
Immediately below and extending to the rear of the barrier material supply is a mold plate 38. This is an inverted V-shaped plate mounted on an arm 40 extending forwardly from the ridge of the mold plate and upwardly to a connection with the frame cross member 28. The mold plate 38 is arranged such that its longitudinal edges ride ln the furrows produced by the plow discs 20. At the trailing end of the mold plate 38 is a yoke 41 carry-130491'75 ing a depth control wheel 42.
Cooperating with the mold plate to form thebarrier from the material on roll 32 is a drum 44 with a double-cone shape matching the v-snape of the mold plate 38. The drum 44 is mounted on a transverse shaft 46 carried in turn by two arms 48 projecting downwardly and to the rear from a frame cross member 50.
Barrier material from the roll 32 runs off the bottom of the roll, over the mold plate 38 and under the drum 44. The engagement of the drum 44 with the mold plate 38 shapes the barrier material into an inverted V-shape and seats it with its longitudinal edges in the furrows opened by the two plow discs 20.
To the rear of the drum 44, on either side of the mold plate 38 are two furrow closing plates 52.
These are rearwardly converging plates mounted on the frame 12 by respective struts 54. They intercept the rows of material displaced by the plow discs 20 and dis-place it back into the furrow, against the sides of the barrier where it has been formed by the mold plate 38 drum 44.
The two rear wheels 16 of the barrier forming apparatus are located to receive the formed barrier between them and to press on the material displaced back ~304975 into the furrows by the closing plates 52.
Figure 3 illustrates a barrier 56 that is con-structed of flexible material 58 reinforced with trans-verse ribs 60. The strip of flexible material is formed into an inverted V-shape along the hinge line 62. A
single barrier of this sort is useful as a barrier to moving air, soil, water, snow or other materials. The flexible material of the barrier may be a natural or syn-thetic fiber fabric, wire, plastic, or other material that may be stored in a roll. The porosity of the mater-ial depends on the specific application. The ribs have been described as being "rigid". It ls to be understood that the rigidity is sufficient to support the barrier for its intended use but may otherwise be resilient or deformable.
Figure 4 illustrates an alternative embodiment of barrier in which two parallel ridges 64 are formed along opposite longitudinal edges of the barrier mater-ial. The two ridges are joined by a panel 66. Where a structure of this sort is made of an impervious material, it may be used as a self-supporting, above ground channel or ditch. A barrier of this type may be laid with an apparatus having two widely spaced plow instruments and a mold plate with the double V configuration of the barrler.
While certain embodiments of the present invention have been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention. Thus, for example, the barriers specifically described in the foregoing have inverted V-shapes, but it is possible to construct the barriers with other upwardly convex configurations as seen in transverse cross section, for example, an invert-ed U-shape, It is also to be understood that rigid barriers, that is barriers made of a barrier material that i8 not flexible in the sense that it cannot be stored in a roll of material may be employed for the pur-pose of the ~resent invention.
It is possible for the barrier to be construct-ed with the ribs extending beyond the edges of the barrier. The plow and furrow closing implements may then be omitted and the ribs ends driven into the ground by a second, heavy roller behind the forming roller.
In another form of the barrier, the flexible material extends beyond the ends of the ribs to form a sod, cloth along the edges of the barrier that may be held down by earth, snow or other material.
The invention is therefore to be construed as g limited solely by the scope of the appended claims.
The present invention relates to barrier sys-tems and to methods and apparatus for installing the barrier systems.

Immedlately behind the plow discs 20 is a barrier material supply. This is a roll of flexible material mounted on a transverse shaft 34 in bearings 36.
Immediately below and extending to the rear of the barrier material supply is a mold plate 38. This is an inverted V-shaped plate mounted on an arm 40 extending forwardly from the ridge of the mold plate and upwardly to a connection with the frame cross member 28.

Cooperating with the mold plate to form thebarrier from the material on roll 32 is a drum 44 with a double-cone shape matching the v-snape of the mold plate 38. The drum 44 is mounted on a transverse shaft 46 carried in turn by two arms 48 projecting downwardly and to the rear from a frame cross member 50.

The engagement of the drum 44 with the mold plate 38 shapes the barrier material into an inverted V-shape and seats it with its longitudinal edges in the furrows opened by the two plow discs 20.
To the rear of the drum 44, on either side of the mold plate 38 are two furrow closing plates 52.
