SNOW FENCE F iled Dc-t. 15, 192B LJ INVENTQR;

Patented July 1, 1930 UNITED STATES OHAUNOEY I. BROWN, OF N OR'I'HFIELD, MINNESOTA SNOW FENCE Application filed October 15, 1928. Serial No. 312,610.

This invention relates to an improved snow fence and the main object is to provide an all metal, highly eflicient and easily assembled fence of said kind involving optionally or as conditions may require a certain simple and eflicient bracing device. I

A further object is to provide a snow fence of the character mentioned and in which horizontal metal slats orboards are used, the

posts of said fence having new and novel means for retaining said boards, and the latter made with novel holding'means engaged by said retaining means of the posts at their opposite ends. These metal boards are also madein a manner providingdesired rigidity. Ot'her objects and advantages are hereinafter fully set forth, reference being had to the accompanying drawing," in which,- j 7 Fig. 1 is a face view or elevationofa section of my improved snow fence set up in operative position. i

Fig. 2 is an enlarged partly sectional side elevation or edge view about as on line 2-2 in Fig. 1 showing the snow-fence in slightly inclined position and certain bracing means therefor. I

Figs. 6 and 7 are fractional detail views of modified forms of the upper post engaging ends of the braces used with this snowfence.

Fig. 8 is an enlarged perspectiveview of an end of a modified slat and Fig. 9 is a sectional elevation of a modified post and brace 14.

In the drawing like numerals of reference indicate similar parts in the several views, and referring tosaid drawing and numerals 10 represents the posts or standards of my improved fence and comprising preferably a light angle ironbar with one flange wider 50 than the other, the wider flange hereinafter designated as the face flange and being provided with the board holding means. 'It will be understood that these posts are driven into the ground with any suitable'driving means, the posts set in such a manner that their wider or face flanges are in a common upright plane, either vertical or in any suit able inclined plane. i

In the said face flange of vide a number of preferably equally spaced integral fingers 10F punched out of the post metal forwardly and bent upwardly, each parallel therefore to theface of the flange with its upper end free and its lower end connected to the flange at the lower end of the slot thus made in the flange. The lower part of the post has of course no'fingers as this end is driven into the ground until the lowest finger 10F is a predetermined distance above the ground surface. These fingers come prise the only fence board retaining means, said boards being slipped downwardly over the free ends of a finger and to resting position at thebase thereof. For convenience the boards, designated 11, will. hereinafter be called slats.

' Each slat 11 comprises an elongated quadrangular piece of sheet metal, preferably a galvanized sheet of weather proof rust resist- 7 ing metal. Parallel to and adjacent each long edge of the slat it is fluted orridged as l at 11R, preferably in V shape in crosssection, thus providing flat edge flanges in a plane with the major part of the slat between the ridges. This provides ample stiffening means foreach slat, the length of the latter peing optionaljbut preferably about eight eet.

Near each end of the slat I punch out four longitudinal slots 12, one pair at the base parts of each ridge and all four slots in alinement transversely of the slat. these slots being allin angular planes in the sloping sides of theridges 11R (see Figs. 1 and 2).- The posts must belocated accordingto the distances between the said slots'12, each slat be ing slipped downwardly with its lower edge between fingers 10F and theadjacent face of thepost so that its lower slots 12 are slidably engaged on h rizonta y registering fingers of each" post Ipro- Cit adjacent posts, until the lower edge 11E of the slat comes to rest at the bottom parts of said fingers'while each said finger projects through and upwardly of a pair of the lower slots of the slat, the upper part of the finger bearing lightly against the main outer face of the slat above said pair of slots, see Fig. 2. The opposite longitudinal edge portions of each slat are identical and therefore either edge may be turned down to engage or'be engaged by fingers 10F as just described. A continuous fence of unlimited length may be made by overlapping end parts of theslats until their slots are alined vertically and slipped down on the fingers of a post as described (see right side of Fig. 1).

-Wher'e joining and overlapped slat ends are mounted it is obvious that there are two thicknesses'ofsheet' metal (as in Fig. 2) retained bythe fingers 10F, but at the end of a fence there willbe only one thickness which would mean that at said ends the fingers retain the single "thickness comparatively loosely but this condition is readily overcome by simply hammering the fingers toward the face of the post' until each said finger bears tightly against the slat or may be slightly impressed thereinby the hammering action.

In Fig. 8 the ridges 0r ribs 11B are terminated short of the end of the slat as at 11R and ashort rib as 11R may be formed as a continuation to the end as at 11R, ornear said end, projections such as 11P may be formed in the rnetal,leaving a plain transverse surface across. the slat, which surface is slipped between the post 10 and finger 10F, the latter indicated in dotted lines. This construction prevents end slippage without providing slots 12. v

For efliciency in manufacture, the fingers 10F are punched from the metal in each face flange of a post, being connected to the. flange at its. lower end as described, the finger being thus integral and spaced from and parallel to the said face as shown. Said fingersv may be separate pieces suitably fixed. on the flange (not shown) by welding or riveting but these variations would of course be simply mechanical expedients. a V

The fence may be set up as described, either in a vertical or angular plane, the best conditionhaving been'fo'und to put it up at an angle about 23 degrees from the vertical, about as in Figs. 2 and 3. In many cases, the character of soil} and subsoil is such that there .is ample rigidity of'the posts but where conditions require it I provide brace rods 14, preferably of round bar iron, each arranged to detachably engagefthe post in, spaced relation to the groundand extend thence downwardly and angularly from the post to the ground level, the lower end of each brace comprising ,preferablyfaloop' or eyel iE resting flat on the ground and'i'n the) eye of. which is insertible dow'nwardlyzan anchor pin 15 tapered" to be driven into the ground, said pin having a head 15H preferably with an aperture for the purpose of facilitating removal of the pin from the ground. The upper end of these braces may be formed in various ways, for example, to engage in an aperture 16 provided in the face flange or other flange of a post and between fingers 10F.

In the form of brace shown in Fig. 2 its upper end is of elongated Z-shape, the extremity of which 14X is inserted in an aperture 16 and bears against the face flange, below which its adjacent bent part is within said aperture and below the aperture part llX bears against the opposite side of the flange and thence the main integral arm extends diagonally to its lower terminus. In the modified forms shown in Figs. 6 and 7 the upper brace end, as in Fig. 6, is an outwardly opening -shaped member hooked into aperture 16, the extreme end 14D projecting downwardly. In Fig. 7 the engaging end comprises an upwardly opening V-shaped member hooked into aperture 16 with the extreme end 14E projecting upwardly from the flange. The construction providing an aperture engaging hook on the upper end of each brace is variable for satisfactory holding and removability only when the lower brace end is free, no particular construction being favored except the form shown in Fig. 2. It is sufficient if any form-of removable hook is used embodying a bent end positively but removably engaging the aperture 16, and preferably if it has shoulder portions bearing against one or opposite faces of the flange to prevent rattling. As a further brace modification Fig. 9 illustrates the upper end of a brace 14 bent in a horizontal plane to conform to the shape of the post, as at 148, to grasp the post as shown, thus eliminating the aperture 16.

In Fig. 3 the dotted lines 17 indicate a drift of snow asit forms in front of thistype of fence. If the fence is mounted as shown, in parallel, spaced relation to a road 18, the fence will not clog with snow, the slats causing wiudblown snow to deflect in a Whirlpool effect and the snow is actually stopped and piled up-in spaced relation to the fence,.about as shown. a

My invention has now been fully disclosed andits. simplicity of construction and erectionwill bereadily understood.
