This invention relates to road guards.

Referring to the accompanying drawings:

Figure 1 is a brokenand compacted side view of the preferred form of the invention.

Figure 2 is an enlarged top view of this preferred form.

Figure 3 is a sectional view taken from the line III-III in Figure 1.

Figures 4 through 13 are views similar to that of Figure 2 but showing various possible modifications of the preferred form.

More specifically, Figures 1 through 3 show a road guard which includes a series of upstanding posts I. The end ones of these postsmount turnbuckles 2 which carry sheaves 3 around which endless wire ropes l are bent. These wire ropes extend transversely past all of the posts excepting the end ones, and the latter are braced against the pull of these ropes by means of anchorage bars 5 which connect with turnbuckles 6. The functions of these various turnbuckles lapping, the outer end portion 3 having aseries.

of parallel longitudinal slots l extending backward from a line near the free edge in a circumferential direction to a distance sufllcient to permit the free play of the cables therein. The ears 9' are bent in at the ends of the slots to provide bearing surfaces for the cables. when the cable bears inwardly (toward the post) against either or both of these ears, it will press them and the corresponding portion of the loop inward while sliding freely thereon.

The bracket is fastened to the post at its inner central portion by bolts II. The cables 4 in the slots l0 bear also against the inner end 8 of the inner portion of the bracket. A pin l2 passes between the cables and the outer end portion 9 of the bracket so as to hold the cables firmly against the inner end portion 8.

When a car strikes the guard, say at the'point X (Figure 2), the cables are bent in as indicated in dotted lines. The free ends of thebracket I are bent into the positions shown in dotted. lines,

collapsing or coiling further about each other.

Since the cables are free to slide longitudinally, they themselves take practically all the'longitudinal stress. Therefore, the resultant pressure PATENT 'OFFICE on the bracket is in the transverse direction indicated by the arrow Y. This transverse force is taken up by the coil spring action of the bracket.

The invention is applicable to road guards of various other kinds. The guard rail may consist of the wire cable or rope illustrated in Figures 1, 2 and 3, or it may be made of flat' strips, woven wire fabric, or other material. The transversely reacting spring bracket may also be made 10 of various other materials than the fiat spring metal illustrated and may be made in loops or other shapes as square, elliptical, cylindrical, etc. So also the fastening means may be varied by the substitution of various types of clamps, clips, bolts or the like, for those above described.

With the above in mind, some of the various possible modifications of the invention are illustrated by the drawings and will now be described.

It might be mentioned at this point that the form of post is entirely immaterial. In Figures 1 through 3 the posts are illustrated as being made from rail sections. However, in the various modifications which are to be disclosed the posts are shown as being made of wood.

Figure 4 shows a post IS, a piece of flat metal formed into a cylindrical loop with its respective ends overlapped at one side, as at l6, and a bolt 2| which passes completely through both sides of the loop formed by the piece 20. A wire rope 22 extends past this post l9, and the piece 20 is provided with a circumferential slot in which this rope 22 is retained by means of a pin 23 in much the same manner as was disclosed in the preferred form of the invention.

Figure 5 shows a post to which a piece of flat metal 3| is circumferentially mounted by means of a bolt 32 that extends radially completely therethrough. The ends 26 of this piece 3| are turned inwardly and ride against the bolt 32. A wire rope 33 extends transversely past the post 30' and is passed through a slot in the piece 3] in thesame manner as was the case in the modification illustrated by Figure 4.

Figure 6 shows a post 34 to which a piece of flat metal 35 is fastened by means of a bolt 36. The ends of this piece 35 are turned inwardly and their respectively opposite faces placed in contact with each other inwardly, as at 35. A wire rope 31 is mounted by this piece 35 in the same manner as in the case of the form shown by Figures 4 and 5.

Figure '7 shows a post 38 which mounts an endless flat metal loop 39 by means of a bolt 40,

and a wire rope 4| is mounted by this loop 33 in RHSSUED the same manner as in the case of Figures 4 and 5.

Figure 8 shows a post 42 to which an endless loop 43 of fiat metal is fastened by means of a bolt 44. This loop is characterized in that it has a portion 45 that is opposite the post 42 and which is sharply looped out from the rest. This portion 45 is slotted, and a wire rope 46 is passed through the slot and retained in position by means of a pin 41.

Figure 9 shows a post 48 to which a piece of flat metal 49 is transversely fastened by means of a bolt 50. The ends 5| and 52 of this piece are overlapped at a position opposite the post 48,

and the outer end 52 is looped sharply outwardly and -slotted, a wire rope 53 being passed through the slot and retained in position by means of a pin 54.

In Figure 10 a new form of the invention is encountered. In this a post 55 has a loop of flat metal 56 fastened transversely to it, the ends of this piece 56 being arranged on either of the sides of the post 55 and there fastened by means of a bolt 51. This piece 56 is appropriately slotted so as to mount a wire rope 58 that is retained in position by means of a pin 59.

Figure 11 illustrates a modification that is much like that described above. Either side of apost 60 mounts two pieces of flat metal 6| and 62 which cooperate to form a loop and which are respectively fastened to the sides of the post 66 by means of a single bolt 63. The respective ends of these pieces 6| and 62 overlap and are slotted, a wire rope 64 being retained in the slot by means of a pin 65.

Figure 12 shows a post 66 to one side of which a pieceof fiat metal 61 is fastened by means of a bolt 68. This piece is curledaround to form a cylindrical loop that contacts the front of the post 66, the portion of this piece opposite the post 66 being slotted so as to mount a wire rope 69 in the same manner as has'been described.

In Figure 13 a post 10 is characterized by having its front face curved, and a piece of fiat metal II is bent into the form of a cylindrical loop and fastened transversely to this curved face by means of a bolt 12. A wire rope 'I3 is mounted by this piece H in the same manner as has been described in connection with the modification illustrated by Figure 11.
