Abstract
Abstract An adjustable fence is provided comprising cylindrical fence posts, inverted channel-shaped rails running between the posts, and vertical panels attached to the rails. The rails are attached to the fence posts by collars which can be rotated on the posts and adjusted vertically and are pivotally connected to the rails to adapt to any terrain. The panels can be attached to either side of the rails by clamps which extend upwardly into the channels of the rails, and the clamps before tightening are adjustable longitudinally of the rails, allowing the panels to be adjusted to be vertical. The clamps are of narrower width than the panels so that if desired panels at one side of the rail can be arranged in edge to edge contact with one another.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
95 words
A fence comprising longitudinal rails defining continuous longitudinally extending channels, panels that can be erected vertically, parallel to one another and transversely to the rails, and clamps for affixing the panels to the rails, the clamps being slidably engageable in the channels of the rails for adjustment of positions of the panels therealong, the clamps being of narrower width than the panels so that if desired the panels can be arranged in edge to edge contact with one another, and releasable means for securing the clamps in fixed relationship with the panels and the rails.
Claim 2
Dependent Claim
95 words
A fence comprising longitudinal rails defining continuous longitudinally extending channels, panels that can be erected vertically, parallel to one another and transversely to the rails, and clamps for affixing the panels to the rails, the clamps being slidably engageable in the channels of the rails for adjustment of positions of the panels therealong, the clamps being of narrower width than the panels so that if desired the panels can be arranged in edge to edge contact with one another, and releasable means for securing the clamps in fixed relationship with the panels and the rails.
Claim 3
Dependent Claim
38 words
A fence as claimed in claim 1, wherein the channels are defined in the underside of the rails and the clamps can extend upwardly into said channels from either side thereof to affix panels at either side thereof.
Claim 4
Dependent Claim
28 words
A fence as claimed in claim 2, wherein the channels have inturned lips embraceable by the clamps to effect said slidable engagement of the clamps with the rails.
Claim 5
Dependent Claim
34 words
A fence as claimed in claim 3, wherein the clamps comprise resilient members, and the means for securing the clamps are screws passing through the panels which can tighten the clamps against the rails.
Claim 6
Dependent Claim
42 words
A fence as claimed in claim 4, wherein the panels comprise resilient metal pans having edges that can bear against the rails and central portions through which said screws can pass to pull the resilient clamps and pans together against the rails.
Claim 7
Dependent Claim
16 words
A fence as claimed in claim 5, wherein the panels have caps at their upper ends.
Claim 8
Dependent Claim
38 words
A fence as claimed in claim 2, including cylindrical posts, and means for adjusting the rails both vertically and rotationally about the posts, said means comprising collars that can encircle the posts and are securable to the rails.
Claim 9
Dependent Claim
16 words
A fence as claimed in claim 7, wherein the collars are pivotally securable to the rails.
Claim 10
Dependent Claim
32 words
A fence as claimed in claim 8, wherein the collars are securable to the rails by pin-in-slot connections, the pins being tightenable to resist movement of the rails relative to the collars.
Claim 11
Dependent Claim
16 words
A fence as claimed in claim 9, including means for tightening the collars on the posts.
