Abstract
Abstract An apparatus for boring horizontally extending holes at shallow depths beneath the surface of the earth having a frame detachably connected to the bucket of a backhoe. The frame is rigidly connected to the bucket for movement thereby and includes a coupling and drive unit which is detachably mounted within the frame so that the coupling and drive unit can be reversed to push or pull an auger connected thereto in opposite directions relative to the bucket.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
157 words
A boring apparatus having a rotatably driven auger for use in combination with a bucket pivotly attached to a movable boom of a vehicular means, comprising: (a) an open upstanding frame means including a pair of spaced upright members and an upper bucket attaching means; (b) means for detachably connecting said upper bucket attaching means to the bucket with said pair of spaced upright members extending outwardly of the bucket; (c) a mounting plate extending between said pair of upright members; (d) means for removably affixing said mounting plate to said pair of spaced upright members whereby said mounting plate can be installed in one of two positions; (e) coupling means affixed to said mounting plate; and (f) power drive means affixed to said mounting plate for rotatingly driving said coupling means whereby said mounting plate can be installed to operate the auger for producing a bore hole in either axial direction with respect to the bucket.
Claim 2
Dependent Claim
157 words
A boring apparatus having a rotatably driven auger for use in combination with a bucket pivotly attached to a movable boom of a vehicular means, comprising: (a) an open upstanding frame means including a pair of spaced upright members and an upper bucket attaching means; (b) means for detachably connecting said upper bucket attaching means to the bucket with said pair of spaced upright members extending outwardly of the bucket; (c) a mounting plate extending between said pair of upright members; (d) means for removably affixing said mounting plate to said pair of spaced upright members whereby said mounting plate can be installed in one of two positions; (e) coupling means affixed to said mounting plate; and (f) power drive means affixed to said mounting plate for rotatingly driving said coupling means whereby said mounting plate can be installed to operate the auger for producing a bore hole in either axial direction with respect to the bucket.
Claim 3
Dependent Claim
92 words
The invention defined in claim 1 wherein said upper bucket attaching means comprises a generally U-shaped member fixedly secured to the upper ends of said pair of upright members and having abutment means extending along one marginal edge engageable with cooperating abutment surfaces on the bucket and a rod extending through aligned apertures provided in said U-shaped member and the bucket for securing the engagement of said abutment means with the cooperating surfaces of the bucket whereby said open upstanding frame means is rigidly held against the outer surface of the bucket.
Claim 4
Dependent Claim
100 words
The invention defined in claim 1 wherein said upper bucket attaching means comprises a flat plate engageable with an outer surface of the bucket and fixedly secured to the upper end of said pair of upright members, hook means pivotally mounted on one edge of said flat plate and engageable with the cutting edge of the bucket and adjustable tie means affixed to and extending between the opposite ends of said flat plate and the pivotal end of the bucket whereby said flat plate of said open upstanding frame means is rigidly held against the outer surface of the bucket.
Claim 5
Dependent Claim
76 words
The invention defined in claim 3 wherein said adjustable tie means comprises a chain secured to the corners of said flat plate, an eye bracket including an elongated threaded member pivotally attached to the pivotal end of the bucket and through which said chain passes and nut means for drawing said eye bracket toward the pivotal connection of the bucket for tensioning said chain whereby said flat plate is drawn into rigid engagement with the bucket.
Claim 6
Dependent Claim
31 words
The invention defined in claim 1 wherein said open upstanding frame means includes a lower surface engaging skid fixedly secured to the lower ends of said pair of spaced upright members.
Claim 7
Dependent Claim
45 words
The invention defined in claim 1 wherein said means for removably affixing said mounting plate to said pair of spaced upright members comprises vertically disposed guideways affixed to the opposed inner surfaces of said upright members for receiving opposed vertically edges of said mounting plate.
Claim 8
Dependent Claim
60 words
The invention defined in claim 1 wherein said means for removably affixing said mounting plate to said pair of spaced upright members comprises a pair of vertically spaced horizontally extending bars affixed to the inner surfaces of said upright members and said mounting plate includes at least two vertical similarly spaced, depending hook members engageable with said horizontally extending bars.
