Abstract
Abstract Line or cable laying apparatus for underground placement of lines characterized by a plurality of channel-shaped elements defining guide chutes separably coupled in a nested or piggy-back arrangement. Each superposed guide chute forms a gate member for an underlying chute. The elements of the assembly feature a can construction which facilitates the ready operation of the gate members. This last feature enables a quick and direct access to any underlying chute to separate a line therefrom, as and when required, without need for a cutting of the line.

Claim 7
Dependent Claim
59 words
A line guide according to claim 4, wherein said last named closing means is another gate member formed to provide a further chute member and wherein means close said further chute member to the rear thereof to provide therewith a third enclosed line guide passage in a separated and spaced relation to said first and second line guide passages.
Claim 8
Dependent Claim
62 words
A line guide according to claim 5, and wherein said means closing said further chute member is a removable gate member, wherein the first said chute member and said removable gate members align with one another and form a unitary device having separable parts providing access to said chutes for a lifting out of guided lines through exposed open rear edges thereof.
Claim 9
Dependent Claim
87 words
A line guide according to claim 4, wherein said chute members have approximately vertically disposing upper line-in openings and approximately horizontally disposing lower line-out openings, said gate member having a portion formed on a radius to facilitate guiding of line elements through said first chute member from the line-in opening to the line-out opening, said portion of said gate member enforcing a separation of lines in said first and second chute members and having a dimension to establish a selected vertical spacing between guided lines emerging therefrom.
Claim 10
Dependent Claim
46 words
A line guide according to claim 4, wherein the first said chute member has a channel-like configuration, said gate member interfitting with to close an open side of the said first chute member and having longitudinally spaced apart locations of connection to said first chute member.
Claim 11
Dependent Claim
87 words
A line layer according to claim 8, wherein said gate member received in a closing relation to the open side of the first said chute member has means to bear on and embrace opposing side walls thereof to prevent spreading thereof, the said side walls of said chute member having recess means pivotally accommodating said bearing and embracing means, and interengageable means on said gate member and said chute member utilizing relative pivotal motion therebetween to force said bearing and embracing means out of said recess means.
Claim 12
Dependent Claim
277 words
A line guide for use in a line layer providing a blade adapted to mount a line guide in a connected following relation to said blade, said line guide including a first chute member mounting rearwardly of said blade to be in a substantially linear following relation thereto, said first chute member having a channel-like configuration providing an upper line-in and a lower line-out opening, a closed edge of said first chute member facing forwardly toward said blade and an open edge facing rearwardly, and a plurality of gate members aligning in a piggy-back relation to said first chute member and to one another, at least a first one of said gate members having a wall portion substantially to close the open edge of said first chute member and to define therein a first substantially enclosed line guide passage, and having further a chute forming portion of channel-like configuration providing a second chute member the closed edge of which is defined by said wall portion, said second chute member being open at an edge oppositely of said wall portion, and another of said gate members substantially closing said open edge of the said first one of said gate members to define therein a second substantially enclosed line guide passage in a spaced separated relation to the first, said second chute member having line-in and line-out openings at opposite ends thereof for passage of line means therethrough separate from line means accommodated in said first chute member, said gate members being removable for access to line means in said line guide passages selectively to lift out from and to re-install lines through open edes of said chute members.
Claim 13
Dependent Claim

A line guide for use in a line layer providing a blade adapted to mount a line guide in a connected following relation to said blade, said line guide including a first chute member mounting rearwardly of said blade to be in a substantially linear following relation thereto, said first chute member having a channel-like configuration providing an upper line-in and a lower line-out opening, a closed edge of said first chute member facing forwardly toward said blade and an open edge facing rearwardly, and a plurality of gate members aligning in a piggy-back relation to said first chute member and to one another, at least a first one of said gate members having a wall portion substantially to close the open edge of said first chute member and to define therein a first substantially enclosed line guide passage, and having further a chute forming portion of channel-like configuration providing a second chute member the closed edge of which is defined by said wall portion, said second chute member being open at an edge oppositely of said wall portion, and another of said gate members substantially closing said open edge of the said first one of said gate members to define therein a second substantially enclosed line guide passage in a spaced separated relation to the first, said second chute member having line-in and line-out openings at opposite ends thereof for passage of line means therethrough separate from line means accommodated in said first chute member, said gate members being removable for access to line means in said line guide passages selectively to lift out from and to re-install lines through open edes of said chute members.
Claim 14
Dependent Claim
54 words
A line guide according to claim 10, wherein the first said chute member and said gate members are configured in complementary relation to define first and second line guide passages in an in-line relation with portions formed on a radius to present line-out openings which are in a substantially vertically superposed and spaced relation.
Claim 15
Dependent Claim
170 words
