lbottom of the` fencing strip to prevent sagging and'curling of the strip sections between adjacent supporting posts.

" Another object is to provide. spaced intermediate stiffened zones throughout the fencing strip to form an adequate engaging surface for suitable fastening elements employed for securing the fencing strip to the posts.

A particular feature of these stiffened zones is that, in addition to affording an engaging surface for the fastening elements at any desired point throughout the length of the strip, they serve to stiffen the fence between posts along spaced narrow zones paralleling the top and bottom of the fence.

Another feature is in the provision of woven twisted strands of paper which are treated with a waterproofing compound and fungicide, rendering the fencing impervious to deterioration by weathering or fungus rot. The above and other objects and features characteristic of this invention will be understood more readily from the following detailed description taken in connection with the accompanying drawings, in which- Fig. 1 is a perspective view showing a fencing embodying my invention as it would appear on a line of posts.

Fig. 2 is an enlarged fragmentary view of the fencing in Fig. 1, showing the selvage portion secured to a post.

Fig. 3 is an enlarged fragmentary view showing an intermediate portion secured to a post. Fig. 4 is a fragmentary view in perspective showing the reverse side of the selvage portion with a fastening element trained therethrough. Fig, 5 is a sectional view, enlarged, taken along the lines 5-5 of Fig. 2. v

Fig. 6 is a sectional view, enlarged, taken along lines 6`6 of Fig. 3.

l Referring more particularly to the drawings, Fig. 1, generally depicts a snow fencing 5 secured to conventional upright posts 5 by suitable fastening members 1. Twisted strands of paper A which have been impregnated with a waterproofjing compound and a fungicide, are woven warp v and weft-wise. as indicated at 3 and 9, respectively, to provide an open mesh fencing. Selvage 2 claims. (c1. 139-425) Y portions l0 at the top and bottom of the open mesh fencing are formed by crowding a plurality of the warp strands together during the weav.. ing operation and by incorporating in the weave of the selvage portion a reinforcing` wire Il' at the time of weaving. In Figs. 2, 4 and 5, I have shown, in detail, one of the selvage portions l0 illustrating how the warp strands interwoven with weft strands 9, are crowdedfto form a relatively close mesh. Y The' reinforcing wire,` 1| is shown interwoven with the weft-wise strands 9 between` two warp-wise strands 8.

The fencing 5, as previouslyindicated, is woven to generally provide an open mesh between the top and bottom selvage portions I 0. Intermediate stiffened zones l2, are provided which extend in spaced parallel relation to the selvage portions. rlhese stiffening zones are formed by crowding groups of the warp strands 8 closer together than in the remaining portion of the weave, as shown in Figs. 3 and 6.

The woven mesh fencing is made up in any desired length which is usually done up in rolls for storage and transportation. To install a snow fence of this kind, a row of posts 6 are first set up in suitable spaced relation. The height of the posts above the ground will be governed by the width of the fencing. The normal width of such fencing is 4 feet but this may be varied to meet specific requirements. The posts are preferably provided with side openings 'la adjacent the top and bottom. The outer end of a roll of fencing is then secured at the selvage portions It by fastening elements 1 to the top and bottom of the first post. Fastening elements 1 preferably comprise strands of twisted paper treated with a waterproofing and fungicidal compound but may be of cord or wire strands. The strands l are trained through a plurality of the weft strands 9 in the selvage portion l0 so as to provide a loop or bight across a plurality of the warp strands 8. The free ends of elements 1 are then fastened about'the post with one end projecting through'openings 'la in the post to hold the fencing, top and bottom, against sliding movement on the post. The intermediate stiffening zones l2 also have fastening elements 1 similarly trained through portions of the closely spaced warps and wefts. said elements being tied around the post to hold the intermediate portions of the fence to the postsat the stifening zone, The post may be provided with additional openings similar to the openings la intermediate the top and bottom through which one vstrand of the fastening elements l at the intermediate stiiiening zones I2 may be trained before said fastening elements are secured to the posts. As the fencing is unrolled it is similarly secured to each successive post in the row in the manner above described.

It will be appreciated that the woven wire l serves as a reinforcement to the stiifened selvage portions to prevent sagging and curling of the fencing between posts. The intermediate stiffening zones I2 havetheir warps suiiiciently crowded together to ensure that the loop of the fastening element 1a will overlie portions of the warps and grip same without distorting. the fencing. These stiifening zones also serve to stilfen the fence throughout` its length along spaced narrow zones paralleling the upper and lower edges of the fence.

Although I have shown the stiifened zones eX- tending parallel to the selvage portions, the stiffened zones may also be arranged to extend between the selvage portions and at right angles thereto. This would beY accomplished by crowding groups of the weft strands together. With this modified form care would have to be exercised in spacing the fence posts to ensure that the fence would be secured to the post at the stiifened zones.

I claim:

'1. A fencing strip formed of twisted strands of paper including warp and weft strands woven together to provide an open mesh paper fence, f

said fencing strip having stiffened selvage portions formed by crowding a plurality of the warp strands together and. warp-wise reinforcing wire REFERENCES CITED The following references are of record in the le of this patent:
