Abstract
Abstract A method and apparatus for supporting pipe employing a plurality of spaced pipe carriers driven into the ground. Each pipe carrier includes a straight rigid body formed from rod stock of rectangular, i.e., square, cross-section. The lower portion of the body is provided with opposed, rigid upwardly diverging barbs, also of rectangular, i.e., square, cross-section. The upper end portion of the body carries a rigid pipe cradle. In one embodiment, the cradle is formed by spaced, laterally projecting, brackets. In other embodiments, the cradle is curvilinear, opening upwardly or downwardly. In still other embodiments, the cradle is an annulus. The cradles and barbs are formed of the same rectangular, i.e., square, rod stock as the body. The opposed surfaces of each cradle is in the same common plane with the opposed surfaces of the body and these planes are perpendicular to the surfaces of the barbs. The cradles, radially, partially or completely circumscribe the periphery of the pipe. In one embodiment the cradle is connected to a sleeve so as to be moveable in a vertical path along the body. The method includes embedding the barbs in the unfilled dirt, by repeated stricking the upper end of pipe carrier. Then, back filling the dirt and mounting the pipe in the cradle followed by covering the pipe with fill dirt.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
92 words
Apparatus for supporting a circular pipe comprising: (a) a straight rigid body having an upper end and a lower end; (b) rigid opposed barbs protruding sidewise from said body adjacent its lower ends; and (c) a cradle carried by the upper end portion of said body, said cradle forming an opening for receiving and confining against appreciable movement therein a radial portion of a pipe; (d) the lower end portion of said body being adapted to be driven into firm ground to a position which embeds the barbs in the firm ground.
Claim 2
Dependent Claim
92 words
Apparatus for supporting a circular pipe comprising: (a) a straight rigid body having an upper end and a lower end; (b) rigid opposed barbs protruding sidewise from said body adjacent its lower ends; and (c) a cradle carried by the upper end portion of said body, said cradle forming an opening for receiving and confining against appreciable movement therein a radial portion of a pipe; (d) the lower end portion of said body being adapted to be driven into firm ground to a position which embeds the barbs in the firm ground.
Claim 3
Dependent Claim
45 words
The apparatus defined in claim 1 wherein said cradle includes a pair of parallel vertically spaced brackets, the ends of which are secured to the side of said body, for receiving said radial portion against said brackets and said upper end portion of said body.
Claim 4
Dependent Claim
19 words
The apparatus defined in claim 2 wherein said brackets project perpendicularly with respect to said barbs from said body.
Claim 5
Dependent Claim
18 words
The apparatus defined in claim 1 wherein said cradle includes a curvilinear member which partially circumscribes said pipe.
Claim 6
Dependent Claim
30 words
The apparatus defined in claim 4 wherein said curvilenear member is U-shaped and includes a semi-circular central portion and a pair of parallel sides protruding tangentially from said central portion.
Claim 7
Dependent Claim
23 words
The apparatus defined in claim 5 wherein said U-shaped member is secured by its central portion to the upper end of said body.
Claim 8
Dependent Claim
23 words
The apparatus defined in claim 5 wherein said U-shaped member is secured by one of its arms to the side of said body.
Claim 9
Dependent Claim
12 words
The apparatus defined in claim 7 wherein said U-shaped member opens upwardly.
Claim 10
Dependent Claim
12 words
The apparatus defined in claim 7 wherein said U-shaped member opens downwardly.
Claim 11
Dependent Claim
19 words
The apparatus defined in claim 1 wherein said cradle is an annulus secured to one side to said body.
Claim 12
Dependent Claim
52 words
The apparatus defined in claim 1 wherein said cradle includes an annular member having a sleeve slidably carried on said body, and a setscrew threadably received by said sleeve and projecting therethrough for engagement with the side of said body, said annular member being secured by its outer periphery to said sleeve.
Claim 13
Dependent Claim
41 words
The apparatus defined in claim 1 wherein said body is rectangular in cross-section and wherein said barbs protrude from opposite surfaces, and said cradle is secured to a third surface of said body, said cradle being disposed perpendicularly to said barbs.
Claim 14
Dependent Claim
41 words
The apparatus defined in claim 12 wherein said barbs are rectangular in cross-section and correspond in thickness to the thickness of the body so that the surfaces of said barbs are disposed in common planes with opposite surfaces of said body.
Claim 15
Dependent Claim
62 words
A process for supporting a pipe in loose dirt comprising the steps of passing vertical standards into the ground in staggered relationship along the path of the pipe so that alternate standards are disposed on opposite sides of said pipe and securing said pipe to the upper portions of said standard alternate sides thereof and thereafter covering said pipe with loose dirt.
Claim 16
Dependent Claim
62 words
A process for supporting a pipe in loose dirt comprising the steps of passing vertical standards into the ground in staggered relationship along the path of the pipe so that alternate standards are disposed on opposite sides of said pipe and securing said pipe to the upper portions of said standard alternate sides thereof and thereafter covering said pipe with loose dirt.
Claim 17
Dependent Claim
28 words
The process defined in claim 14 wherein the step of supporting the pipe from said standards includes securing said pipe by brackets to side portions of said pipes.
Claim 18
Dependent Claim
84 words
The process of supporting a pipe in loose dirt composing: (a) disposing a plurality of pipe carriers at spaced locations along the path of said pipe, each of said carriers having a rigid straight body with a barbed lower end portion and a cradle for the pipe at its upper end portion; (b) driving each of said carriers, lower end portion first, into the ground so as to embed the barbed end portion into firm dirt; and (c) installing the pipe in said cradles.
Claim 19
Dependent Claim
84 words
The process of supporting a pipe in loose dirt composing: (a) disposing a plurality of pipe carriers at spaced locations along the path of said pipe, each of said carriers having a rigid straight body with a barbed lower end portion and a cradle for the pipe at its upper end portion; (b) driving each of said carriers, lower end portion first, into the ground so as to embed the barbed end portion into firm dirt; and (c) installing the pipe in said cradles.
