The picket-fence of the present invention is formed of relatively thin-walled metallic tubing (preferably steel tubing) of rectangular cross-section. The vertical posts and pickets are of square cross-section. The horizontal rails are of oblong rectangular cross-section, with the major dimension of the cross-section being horizontal and the minor 7 dimension of the crosssection being vertical. The posts are provided with upper and lower oblong rectangular holes at the levels where the upper and lower rails are to be located; such holes being of a size which will receive. the outer surfaces of the rails with a neat working clearance, or with picket is inserted into the picket-receiving hole of the rail, the spring-tang will be depressed until its free end a clearance just sufficient to permit the insertion of the 7 ends of the rails into the posts without undue frictional interference. The ends of the rails are provided with a pair of spring-tangs pressed out from one of the walls thereof, with the ends of the tangs facing each other and spaced from each other a distance approximately equal to or slightly greater than the thickness of the wall of the tubular post, so that when the end of the rail is inserted into the rail-receiving hole in the post, the outboard spring-tang will be depressed momentarily until the wall of the post along the edge of the hole therein passes such tang and has its outer surface disposed against the end of the'inboard tang; whereupon the rail becomes locked to the post with the wall of the post between the two spaced-apart ends of the pair of locking tangs.

In one embodiment of the invention, the pickets terminate within the upper and lower rails, and the railentering ends of such rail-terminating pickets are snaplocked to the rail by spring-tangs described hereinafter.

In the rail-terminating-picket embodiment of the in-.

vention, the lower wall of the upper rail and the upper wall of the lower rail are provided with vertically aligned rectangular picket-receiving holes matching the outer dimensions of the pickets. T hepickets are provided with single springtangs pressed outwardly from the end portions of the wall thereofland with the free ends of such tangs facing away from the ends of the pickets, and with the distance between the end of the picket and the free end of the spring-tang being approximately the same as or slightly less than the interior v'ertical dimension of the rail, so that when the end of the hinge-post.

passes the wall of the rail, whereupon the spring-tang snaps back into its original position and the picket is therefrom to a slight extent and disposed adjacent to the upper and/or lower walls of the rails, so as to lock the pickets in place in relation to. the rails. Such slight beads or ribs can be formed by means of a simple manuallyoperable tool inserted into the free open end of the picket to a depth corresponding to the desired location of the rail, such tool having upper and lower pairs of opposed tube-expanding projections, so that by turning the tool a quarter of a turn or so (or perhaps a half a turn), by means of an external handle, the walls of the picket are forced outwardly to a slight extent to form slight ribs or beads which interlock with the upper and/or lower walls of the rail.

DESCRIPTION The picket fence of the present invention includes tubular line-posts 31 at suitably spaced intervals (as, for instance, 6 feet or so apart), corner posts 32, a gatehinge-post 33 and a gate-latch-post 34, and upper and lower rails 35 and 36 (respectively) between successive line-posts 31 and between the corner-post 32 and the line-posts nearest thereto and between the gate-hingepost 33 and the line-post 31 nearest thereto and between the gate-latch-post 34 and the line-post 31 nearest thereto. Vertically disposed tubular pickets 37 extend between upper and lower rails 35 and 36. The gate, designated generally by the numeral 38, is formed of the gate-hinge-stile 39, the gate-latch-stile 40, and an upper gaterail 41 and a lower gate-rail 42 and gatepickets 43 between the gate-rails 41 & 42.

The line-posts 31 and the corner-posts 32 and the gate-posts 33 & 34 and the gate-stiles 39 & 40 are preferably formed of square welded steel tubing of suitable size, as, for instance, a 2 inch or so square tubing having a wall-thickness of about 0.035 inch to 0.060 inch (more or less). The rails 35, 36, 41, & 42 may be formed of welded steel tubing or of lock-seam steel tubing of oblong rectangular cross-section of suitable size, as, for instance, with its horizontally disposed major outer cross-section dimension being an inch and a quarter or so and with its vertically disposed minor dimension being three quarters of an inch or so. If these rails are formed of welded steel tubing then the wall thickness thereof may be about 0.035 inch to 0.060 inch (more or less), while if they are formed of lockseam tubing then the wall-thickness thereof may be of the general order of about 0.025 inch, more or less.

If'the horizontally disposed major dimension of the cross-section of the rail is an inch and a quarter or so, then the pickets 37 & 43 are preferably one half-inch square lock-seam tubing having a wall-thickness of the general order of 0.015 inch to 0.025 inch. The pickets are preferably lock-seam tubing.

The line-posts shown in FIGS. 1,'3 & 5 are provided with pairs of opposite rail-receiving holes 44 near the tops thereof and similar pairs of opposite rail-receiving holes 44 near the "bottoms thereof, for receiving the ends of the upper and lowerrails 35 & 36,.respectively,

as. indicated in FIG. 3. The rail-receiving holes 44 are of oblong rectangular shape corresponding to a crosssection of the rails, with their dimensions such as to accomodate the outer dimensions of the rails 35 & 36 with just sufficient working clearance to permit the insertion thereinto of the ends of said rails without undue friction or resistance, except for the need to depress the outboard spring-tangs at the ends of the rails when such ends are pushed into the holes 44 until the ends of the inboard tangs 46 of the rails abut against the outer surfaces 47 of the walls 48 of the post, as indicated in FIG. 3;- at which point the outboard tangs 45 spring back into their open position so that the walls 48 of the posts adjacent the rail-receiving holes are disposed and locked between the facing ends of the spring-tangs45 & 46, thereby locking the ends of the rails to the post. The aforementioned depression of the outboard tangs is aided or augmented by a slight temporary inward deflection of the tang-carrying portions of the rail when the end of the rail is pushed into the rail-receiving hole of the post.

Similar rail-receiving holes 49 are provided in the gate-hinge-post 33 and in the gate-latch-post 34 as indicated in FIGS. 6 & 9. Similar rail-receiving holes 50 are provided in the facing walls of the gate-hinge-stile 39 and the gate-latch-stile 40, as indicated inFIGS. 7 & 8. The two gate-posts 33 & 34 are also provided with similar spacer-receiving holes 51 in their ground-embedded or concrete-embedded lower ends thereof (as indicated in FIGS. l-C, 6 & 9), through which the tubular spacerrail 52 is ended. The spacer 52 has pairs of holes 53 at its opposite ends, flanking the respective gate-posts, into which holes headed pins or bolts or threadless headed members 54 are inserted for holding the lower embedded ends of the gate-posts in the desired spaced relationship to each other, to accommodate the gate 38.

The corner-post 32 is provided with similar upper and lower rail-receiving holes 56 in the wall 58 thereof and with like upper and lower rail-receiving holes 57 in the wall 59 thereof which is at a right angle to the wall 58. The rail-receiving holes 57 8t 58 are off-set from the vertical center-lines of the respective walls S8 8L 59, so that the inner ends 60 & 61 of the two rails 35 clear each other and do not obstruct or interfere with each other, as shown particularly in FIGS. 2 & 2-A.

The rails 35 & 36 and 41 & 42 have pairs of oppo sitely facing spring-tangs 45 & 46 pressed outwardly from their upper and lower walls near the. ends thereof, as indicated in FIGS. 2, Z-A, 3, l0, l2, l3, l4 & 15 for locking the ends of the rails to the posts 31, 32, 33 8t 34 and to the stiles 39 & 40, in the manner indicated particularly in FIGS. 2, 2-A & 3 and described hereinabove.

The pickets 37 & 43 may be provided with pairs of opposite and outwardly flared spring-tangs 62, with their ends facing away from the ends of the pickets, so that when the ends of the pickets are inserted into the picket-receiving holes 63 of the rails (35 8t 36 and 41 & 42), the springdangs will be collapsed or deflected until their free ends 64 have passed the wall of the rail and then snap out again against the inner surface of the wall of the rail. thereby to lock the pickets to the rails as indicated in FIGS. 2 6t 3. Such deflection of the tangs 62 is aided or augmented by a slight temporary inward deflection of the tang-carrying portions of the picket when the end of the picket is pushed into the picketreceiving hole of the rail.

In FIGS. 20 & 21 an alternative form ofpicket'to-rail locking construction is shown. in which a piercing punch 65 is quickly projected through the wall 66 near the end of the picket, in the direction of the arrow 67, untilits slanted end 68 presses a spring-tang 69 outwardly from the opposite wall 70 of the picket. as indicated in FIG. 20. The pickets with this alternative tang construction are inserted into the picket-receiving holes 63 of the upper and lower rails in the manner indicated in FIG. 21, with the free ends of the springtang's 69 engaging against the inner surface of the horizontal walls of the rails as shown in FIG. 21.

In FIGS. 22, 23 & 24, an alternative form of picketto-rail locking construction is shown, in which a picketreceiving hole 63 is provided in each of the two horizontal walls of the upper and lower rails (35, 36, 41 & 42) as indicated in FIGS. 22 & 23, and the ends of the pickets are projected or telescoped through both upper and lower holes 63, with the free ends 71 of the pickets extending a suitable distance beyond the rail, as indicated in FIGS. 22, 23 & 25.

Slight arcuate upper and lower ribs 72 & 73 are then pressed outwardly from opposite walls 74 & 75 of the picket (FIGS. 23 & 24), by means of a tool designated generally by the numeral 76. The tool 76 may be a flat L-shaped piece of steel having a handle-portion 77 and a picket-entering portion 78 provided with opposite upper and lower wall-deforming projections 79 & 80. The distance between the outer ends of the opposite projections 79 as well as the distance between the outer ends of the opposite projections 80) are less than the interior diagonal dimension of the picket but suitably greater than the distance between the inner parallel wall-surfaces 81 & 82 of the picket (FIG. 24), so that the end 78 of the tool 76 may be inserted into the free end of the picket across the diagonal thereof, as indicated in FIG. 24, and then turned 90, so that the pairs of upper and lower projections 79 & 80 sweep across the interior of wall-surfaces 81 & 82 and deform the walls 74 & 75 by pressing the slight ribs or bead-like projections 72 & 73 outwardly therefrom, adjacent to the upper and lower horizontal walls of the rail, thereby locking the picket to the rail in the manner indicated in FIGS. 23 & 24. Opposite spacer-arms 91 extend from the stem 92 of the tool 76 and overlap and bear against thefree end of the picket, so as to spacethe wall-deforming projections 79 & 80 of the tool a predetermined distance from the free end of the picket as in dicated in FIG. 23.

The picket-to-rail locking construction shown in FIG. 22 differs from that shown in FIGS. 23 & 24, in that the outwardly-pressed ribs 83 & 84 flank the outer surfaces of the upper and lower walls of the rail exteriorly thereof (instead of being disposed interiorly thereof as in FIG. 23). The upper & lower rib-forming projections of the end 78 of the tool 76 are spaced apart further, to form the ribs or bead-like projections 83 & 84. After the tool 76 has been turned 90, its end 78 is again disposed diagonally of the picket, so that it can be removed therefrom.

The line-posts 31, the corner-posts 32, the gate-posts 33 8t 34 and the gate-stiles 39 & 40 are provided with suitable square plastic caps 85, as indicated in FIGS. 2 8t 3 (preferably of the same color as the paint or other coating or finish of the posts). The caps 85 have a square tubularlower portion 86 telescoping into the upper ends of the posts with a pressdit or being cemented thcreinto by any suitable cement such as an epoxy cement or the like. Slight horizontal flanges 87 extend outwardly from the caps 85 and overlap the free ends of the walls of the. posts.

In the alternative construction indicated in FIGS. 22, 23 8t 24, in which the free ends 71 of the pickets extend beyond the rails, similar square plastic caps 88 are provided, having tubular portions 89 telescoped into the free ends of the pickets and having similar overlapping flanges 90, and being similarly press-fitted and/or cemented into the free ends of the pickets.

In F IGS. 24, & 26, a picket-spacer jig 93 is shown.

The jig 93 is suitably formed of a sheet metal of suitable rigidity and hardness, and.includes the vertical spacerv of panel 94 and upper and lower horizontal panels 95 & 96 extending therefrom, which panels are spaced apart from each other a distance such as will neatly straddle the rain (35 or 41) as indicated in FIG. 25. The upper panel 95 as well as the lower panel 96 are each of a generally Ushaped formation, with the legs 97 of the upper U-shaped panel and the legs 98 of the lower U-shaped panel neatly straddling the picket, as indicated particularly in FIG. 25. A vertical picket-to-rail spacer-member 99 extends upwardly from the base of the U-shaped upper panel 95, and has a horizontal projection 100 at the upper end thereof which overlaps and bears against the upper end of the picket (as indicated in FIGS. 24 & 25), thereby fixing the length or the extent of the projection of the picket beyond the rail (as indicated in FIG. 25).

In FIGS. 27, 28 & 29 l have shown a modified embodiment of the rail-to-post locking construction, and in FIGS. & 31 I have shown a similar picket-to-rail locking construction.

In the rail-to-post locking construction illustrated by FIGS. 27, 28 & 29, the rail-receiving hole 101 in the post (31 or 32) is provided with a pair of opposite (upper and lower) short inwardly-slanted locking tangs or projections. The end of the rail (35, 36, 41, 42) is provided with corresponding upper and lower tang receiving holes or projection-receiving holes 103, and inwardly-pressed inclined tang-leading or projectionleading portions 104. When the end of the rail is pushed into the rail-receiving hole 101 in the manner indicated in FIGS. 27 & 29, the short tangs or projections 102 ride up on the tang-leading inclines 104 and deflect inwardly ,the upper and lower walls of the rail just sufficiently to permit the tans or projections 101 to reach and snap into the tang-receiving holes 103, whereupon the upper and lower walls of the end of the rail return to their original positions, with the rail locked to the post in a manner indicated in FIG. 29.

A similar locking construction may be provided for locking the picketto the rail in a similar manner, .as indicated in FIGS. 30 & 31. Thus, the picket-receiving hole 106 in the rail (35, 36, 41 & 42) has similar inwardly extending and inwardly-slanted locking prongs or projections 107, and the end ofthe picket has similar prong-receiving or projection-receiving holes 108 and prong-leading inclined portions 109, as indicated in FIGS. 30 & 31.
