Abstract
Abstract A truck-mounted post driver comprises a conventional driver head disposed laterally of the truck bed and mounted for controlled tilting movement in two vertical planes parallel to and transverse to the longitudinal axis of the truck so that the head may be plumbed with respect to a vertical post. The head is carried by an adjustable frame assembly by means of which it can be positioned horizontally and vertically and retracted to a position on the truck body.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
182 words
Post-driving apparatus adapted to be mounted on a wheeled vehicle and suspended from the vehicle comprising: a vertically elongated driving device for guiding and driving a driving head into engagement with the upper end of a post in order to drive the post into the ground; a vertically elongated rigid support member disposed generally parallel to said driving device; means connecting said driving device to said support member in any of several predetermined relative positions along the length of said support member; first drive means for raising and lowering said support member; and second drive means for moving said support member and said first drive means linearly in a horizontal plane, said second drive means including generally horizontal track means adapted to be fixed to a vehicle and a floor structure riding on said track means and extensible horizontally beyond said track means, and said first drive means and said support member being pivotally mounted on said floor structure for swinging movement in a vertical plane between a position horizontally beyond said floor structure and a position directly above said floor structure.
Claim 2
Dependent Claim

Post-driving apparatus adapted to be mounted on a wheeled vehicle and suspended from the vehicle comprising: a vertically elongated driving device for guiding and driving a driving head into engagement with the upper end of a post in order to drive the post into the ground; a vertically elongated rigid support member disposed generally parallel to said driving device; means connecting said driving device to said support member in any of several predetermined relative positions along the length of said support member; first drive means for raising and lowering said support member; and second drive means for moving said support member and said first drive means linearly in a horizontal plane, said second drive means including generally horizontal track means adapted to be fixed to a vehicle and a floor structure riding on said track means and extensible horizontally beyond said track means, and said first drive means and said support member being pivotally mounted on said floor structure for swinging movement in a vertical plane between a position horizontally beyond said floor structure and a position directly above said floor structure.
Claim 3
Dependent Claim
149 words
In a post-driving apparatus of the type including a driving device for guiding and driving a driving head into engagement with the upper end of a post in order to drive the post into the ground and support means for suspending the driving device from a wheeled vehicle and for aligning the driving device with respect to the post, the improvement in the support and aligning means comprising swivel means mounting the driving device for swinging movement in first and second generally vertical planes normal to each other and two linearly extensible and retractable adjustment devices cooperating with the driving devicE for swinging the driving device in one of said planes about a first axis when both adjustment devices are extended or retracted simultaneously and for swinging the driving device in the other plane about a second axis when one adjustment device is extended and the other is retracted.
Claim 4
Dependent Claim
149 words
In a post-driving apparatus of the type including a driving device for guiding and driving a driving head into engagement with the upper end of a post in order to drive the post into the ground and support means for suspending the driving device from a wheeled vehicle and for aligning the driving device with respect to the post, the improvement in the support and aligning means comprising swivel means mounting the driving device for swinging movement in first and second generally vertical planes normal to each other and two linearly extensible and retractable adjustment devices cooperating with the driving devicE for swinging the driving device in one of said planes about a first axis when both adjustment devices are extended or retracted simultaneously and for swinging the driving device in the other plane about a second axis when one adjustment device is extended and the other is retracted.
Claim 5
Dependent Claim
50 words
Apparatus as in claim 2 wherein said adjustment devices are arranged with their longitudinal axes generally parallel to one of the axes of rotation of the driving device and wherein said adjustment devices engage the driving device on opposite sides of the other axis of rotation of the driving device.
Claim 6
Dependent Claim
53 words
Apparatus as in claim 2 wherein said adjustment devices are arranged with their longitudinal axes generally horizontal and generally parallel to one of the axes of rotation of the driving device and wherein said adjustment devices engage the driving device on opposite sides of the other axis of rotation of the driving device.
Claim 7
Dependent Claim
12 words
Apparatus as in claim 4 wherein said adjustment devices are hydraulic rams.
