| 摘要 | An earth perforating implement is provided wherein the effective reach of the implement into the earth beyond first and second projecting means carried on shaft means of the implement differs in order that a hole produced to an initial depth in the earth using one end of the implement can be deepened using the opposite end of the implement, the first projecting means being adapted to receive foot pressure application from the user of the implement in forming the hole to the initial depth and the second projecting means being adapted to receive foot pressure application from the user of the implement in deepening the hole from the given depth. | ||||||
| 权利要求 | 1. An earth perforating implement, comprising, first and second earth perforating members and shaft means interconnecting said earth perforating members, said first and second earth perforating members including oppositely directed first and second earth perforating ends of the implement for a hole to be produced in the earth and extended with said earth perforating ends; and first and second projecting means united with said shaft means and leading outwardly transversely of said shaft means and being spaced apart from said first and second earth perforating ends respectively and from one another having the distance of said second earth perforating end from said second projecting means approximately double the distance of said first earth perforating end from said first projecting means, for a user of the implement to apply foot pressure to said first projecting means and manually grip said second projecting means in producing a hole in the earth with said first perforating end, and for said implement inverted and inserted bringing said second earth perforating end against the bottom of the hole to have lowered said first and second projecting means by an amount represented by the depth of the hole and into accessible positions to have a user of the implement thereafter grip said first projecting means manually and apply foot pressure upon said second projecting means to deepen the hole. 2. An earth perforating implement as set forth in claim 1 wherein each of said first and second projecting means includes a pair of projecting portions leading from said shaft means and longitudinally oppositely directionally on an axis which is transverse to said shaft means. 3. An earth perforating implement as set forth in claim 2 wherein each of said first and second projecting means includes a cross member having an aperture intermediately of said pair of projecting portions of said projecting means, and said cross member accommodating said shaft means in said aperture and being secured to said shaft means. 4. An earth perforating implement as set forth in claim 1 wherein said first and second earth perforating ends of the implement are longitudinally outwardly convergent ends. 5. An earth perforating implement, comprising, shaft means and first and second longitudinally outwardly convergent oppositely directed earth perforating ends of said shaft means for a hole to be produced in the earth and extended with said convergent earth perforating ends, and first and second projecting means united with said shaft means and each of said projecting means including a pair of oppositely projecting portions leading outwardly longitudinally transversely of said shaft means, said first and second projecting means being spaced apart from said first and second convergent earth perforating ends respectively and from one another longitudinally of said shaft means having the distance of said second convergent earth perforating end from said second projecting means approximately double the distance of said first convergent earth perforAting end from said first projecting means, for a user of the implement to apply foot pressure to said projecting portions of said first projecting means and manually grip said projecting portions of said second projecting means in producing a hole in the earth with said first convergent earth perforating end, and for said implement inverted and inserted bringing said second convergent earth perforating end against the bottom of the hole to have lowered said first and second projecting means by an amount represented by the depth of the hole and into accessible positions to have a user of the implement thereafter grip said projecting portions of said first projecting means manually and apply foot pressure upon said projecting portions of said second projecting means to deepen the hole. 6. An earth perforating implement as set forth in claim 5 wherein each of said first and second projecting means includes a cross member and each of said cross members comprises one of said pairs of projecting portions and has an aperture transversely intermediately of said pair of projecting portions thereof, said cross member accommodating said shaft means in said aperture and being secured to said shaft means. |
