Abstract
Abstract A device for driving ground rods of the type to be mounted on a suitable carriage or vehicle. A boom to engage ground rods as the rods are driven is attached to an adjustable horizonal beam. The adjustable horizonal beam interconnects the boom with a vertical cylinder attached to a base. The base interlocks the entire device to the bed or frame of the carriage. The movement of the horizonal beam and rotation of the vertical cylinder combined as a means of positioning the boom relative to the carriage. Attached to the boom is a hydraulically driven impact hammer for power driving the ground rods. The boom is pivotally mounted on the horizonal beam so that the boom may be carried in a substantially horizonal position while in transit and rotated to a vertical position when in use. Also included is a vertical adjustment means mounted on the beam so that the boom may be adjusted vertically to engage with the ground or supporting surface on which the vehicle rests.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
190 words
A device for driving ground rods designed to be mounted on a mobile chassis, said device comprising: base means to mount said device on the chassis, boom means including guide means to operatively engage said ground rod to retain the position of said ground rod relative to said boom means, positioning means including longitudinal positioning means and pivotal positioning means interconnecting said boom means to said base means to operatively position said boom means in the horizontal plane relative to a supporting surface, driving means attached to said boom means and arranged to drive said ground rod when said ground rod is operatively positioned relative to said boom means, control means for actuating said positioning means and said driving means and locking means to fix the position of said boom means relative to said positioning means when said boom means is operatively positioned, said driving means operatively attached to said boom means and aligned with the upper extremity of said ground rod whereby said driving means operatively engages said ground rod to drive said ground rod vertically downward into a supporting surface when said device is operatively positioned and actuated.
Claim 2
Independent Claim
190 words
A device for driving ground rods designed to be mounted on a mobile chassis, said device comprising: base means to mount said device on the chassis, boom means including guide means to operatively engage said ground rod to retain the position of said ground rod relative to said boom means, positioning means including longitudinal positioning means and pivotal positioning means interconnecting said boom means to said base means to operatively position said boom means in the horizontal plane relative to a supporting surface, driving means attached to said boom means and arranged to drive said ground rod when said ground rod is operatively positioned relative to said boom means, control means for actuating said positioning means and said driving means and locking means to fix the position of said boom means relative to said positioning means when said boom means is operatively positioned, said driving means operatively attached to said boom means and aligned with the upper extremity of said ground rod whereby said driving means operatively engages said ground rod to drive said ground rod vertically downward into a supporting surface when said device is operatively positioned and actuated.
Claim 3
Dependent Claim
43 words
A device as in claim 1 wherein said positioning means further includes vertical positioning means interconnecting said boom means and said longitudinal positioning means to operatively position said boom means and said driving means in the vertical plane relative to the supporting surface.
Claim 4
Dependent Claim
54 words
A device as in claim 1 wherein said pivotal positioning means comprises a vertically disposed cylindrical member pivotally mounted on said base such that said boom means and said longitudinal positioning means may be rotated in an arc about said pivotal positioning means to operatively position said boom means relative to said supporting surface.
Claim 5
Dependent Claim
29 words
A device as in claim 1 wherein said locking means comprises a locking lever arranged on said boom means to cooperatively engage a locking post on said positioning means.
Claim 6
Dependent Claim
65 words
A device as in claim 1 wherein said boom means is pivotally connected to said positioning means and mounted on said positioning means in relation to said chassis such that the longitudinal axis of said boom means may be adjusted from a substantially parallel position relative to said chassis during transit to a substantially vertical position relative to said chassis during operation of said device.
Claim 7
Dependent Claim
69 words
A device as in claim 5 wherein said boom means includes a stabilizing means comprising a substantially flat plate attached perpendicularly to the lower extreme of said boom and plurality of spikes arranged parallel to each other and mounted on said plate whereby said stabilizing means engages the supporting surface thereby preventing movement of said boom means relative to said supporting surface when said boom means is operatively positioned.
Claim 8
Dependent Claim
101 words
A device as in claim 1 wherein said guide means comprise a plurality of spring loaded members interconnected to said boom means by substantially U-shaped frame, said spring loaded members arranged in cooperative working relation to both said boom means and said driving means such that movement of said driving means along said boom means will cause said spring loaded members to rotate in the direction of travel of said driving means, whereby passage of said driving means is allowed, said spring loaded members positioned to return to original position relative to said boom means after passage of said driving means.
Claim 9
Dependent Claim
41 words
A device as in claiM 7 wherein said spring loaded members include apertures formed in said members to engage said ground rods such that the longitudinal axis of said boom means when said ground rods are operatively engaged by said device.
Claim 10
Dependent Claim
21 words
A device as in claim 1 wherein said longitudinal positioning means operatively interconnects said pivotal positioning means and said boom means.
Claim 11
Dependent Claim
36 words
A device as in claim 9 wherein said boom means comprises an I-beam and said driving means includes a hammer slide operatively mounted on said I-beam to position said driving means relative to said ground rods.
Claim 12
Dependent Claim
62 words
A device as in claim 9 wherein said longitudinal positioning means comprises a horizontal member connected to said boom means, said horizontal member movably mounted on said pivotal positioning means such that movement of said horizontal member means relative to said pivotal positioning means will cause a corresponding change in the relative positions of said pivotal positioning means and said boom means.
