Abstract
Abstract An elongated beam member is arranged for attachment at its front end to a forward portion of a vehicle. A telescoping support arm is arranged for pivotal connection at one of its ends to the vehicle and at its other end to the beam member. Such arm has powered telescoping length adjustment by an internal fluid operated cylinder. The rearward end of the elongated beam member pivotally supports a plow blade carrier and a cable guide chute, together with a vibrator on the plow blade carrier. Power means such as fluid operated cylinders are utilized to raise and lower the beam member, to raise and lower the plow blade, to adjust the beam member on a longitudinal axis, and to adjust the longitudinal pivotal alignment between the plow blade carrier and the beam member. Warning and vehicle shut-off means are employed to prevent damage to the cable being laid in the event such cable is subjected to too much tension.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
212 words
A cable-laying vehicle comprising a. a longitudinal frame supported on movable means, b. an elongated main frame, c. a plow blade carrier mounted on the rear end of said main frame, d. a plow blade supported by said carrier, e. a cable guide shoe supported by said carrier, f. cable feed means on said vehicle for feeding cable to said guide shoe, g. first universal joint means arranged to connect the forward end of said main frame with a front portion of the vehicle at one side, h. a laterally extending support arm on said vehicle, i. said arm comprising a rigid tubular base portion telescopically receiving a rigid tubular extension in guided relation and a double acting fluid operated cylinder interconnected between said base portion and said extension interiorly thereof and arranged to vary the length of said support arm, j. second universal joint means at one end of said support arm connecting said end to a rearward point on said main frame, k. and means at the other end of said support arm arranged to connect said other end to a rearward point of said vehicle, l. said support arm in its length adjustment being capable of positioning said main frame selected distances at the rear away from said vehicle.
Claim 2
Dependent Claim
212 words

Claim 3
Dependent Claim
62 words
The cable laying vehicle of claim 1 including universal joint means on each side of said vehicle wherein said main frame is arranged to be connected on either side of said vehicle, said second universal joint means being movable from one side of said main frame to the other to accommodate mounting of the latter on said either side of said vehicle.
Claim 4
Dependent Claim
91 words
The cable laying vehicle of claim 1 wherein said vehicle comprises a crawler type tractor and has side track frames, said first universal joint means being connected to a forward portion on said track frames, and a double acting fluid operated cylinder arranged to be connected at one of its ends to said vehicle below the connection of said other end of the arm with the vehicle and connected at its other end to said arm whereby upon actuation of the said cylinder it can raise or lower said main frame.
Claim 5
Dependent Claim
49 words
The cable laying vehicle of claim 1 wherein said vehicle comprises a road grader having a tiltable moldboard guide and support frame, said first universal joint being connected to a forward point on said road grader, and means securing said support arm to said moldboard guide and support frame.
Claim 6
Dependent Claim
99 words
The cable laying vehicle of claim 1 including cable supply means on said vehicle cable guide means on said vehicle between said cable supply means and said cable guide shoe, said cable guide means including a resiliently supported arm arranged in a normal cable feeding operation to project outwardly at a sElected angle but to be pulled downwardly by the cable in the event an abnormal tension acts on said cable in a cable feeding operation, and signal means in the path of said arm actuated in a selected downward position of said arm to emit a warning signal.
Claim 7
Dependent Claim
49 words
The cable laying vehicle of claim 5 including link means connected between said arm and engine control means and arranged in a selected downward pivoted position of said arm past the position at which the signal is actuated to move the engine control means to an engine shut-off position.
Claim 8
Dependent Claim
109 words
The cable laying vehicle of claim 1 including cable supply means on said vehicle, cable guide means on said vehicle between said cable supply means and said cable guide shoe, said cable guide means including a resiliently supported arm arranged in a normal cable feeding operation to project outwardly at a selected angle but to be pulled downwardly by the cable in the event an abnormal tension acts on said cable in a cable feeding operation, and link means connected between said arm and engine control means and arranged in a selected downward pivoted position of said arm to move the engine control means to an engine shut-off position.
