My invention is of value wherever there is easily injured. Another disadvantage is a tendency for snow to drift, particularly that as ordinarily put up in unit rolls of a highways. With the advent of the automonumber of yards'they are heavy to .handle bile and the greatly increased use of the highand the labor cost of erecting the fence is Ways it has now become customary to keep high.

And also because of their frailty they are The snow fence comprises a number (itit. I

supports 10, 10 suitably spaced apart to correspond with the length of the boards to be used. I have found 14 feet to be a satisfactory length of board in which case the supports would be about 13% feet apart.

Each sup ort consists of two members or legs 12mm? 13 of substantially the same length,"hin-ged together 'attheiop as-indi--' cated at 14. I preferabl use a heav sheetmetal for these members ent into a shape as indicated in the pliaiitom cfoss sections 12'.

The material for these members should;

I have also found that the angular disposition of the fence from the vertical is very effective in directing the wind in a manner which could not be attained in a fence that was vertical.

To describe the hinge in detail reference is made to Figs. 2 to 6. A central opening is punched out with a plurality of inwardly projecting .ears, four as shown in the draw- The ears" 19, 19"of member 12 (see Fig-.3) are then bent at right angles toward the right. In Fig. 4 the corresponding member' 13 'is'shown-with its cars 20, 20 bent at right angles toward the left. Members 12 and '13 are then placedtogether so a that the cars 19; 19 pass' through' the-opening of member 13 and likewise ears 20, 20' pass through the opening of member 12. In"

this position" with members 12 and 13 flat against 'each other the ears are bentaround the rest'ofafull 180 degrees. Fig. 5 shows this completed' hinge with the support folded up for transportation; Fig. 6 shows the hinge or joint'openedup for use. It will be noticed thatthe ears are sodesigned that they-provide a stop by coming-together when the hinge has been spread to themaxi'mum angle: for which it was designed. Also the portion'shoulder 21 is cut out at such an angle as to provide a stop. This can best beseelr i rFig: 6i Either the ears orthe shoulder 21or both toge'ther may be used 'for this stop or limit purpose.
