Abstract
Abstract An apparatus for depositing a gelled liquid below the surface of the soil having a plurality of earth-penetrating tools each having a gelled liquid depositing conduit and a bypass conduit attached to the rearward side of the tools terminating below the soil surface. A series of pipes and valves connect containers of gelled liquid, water and inert gas under pressure to the conduits and are positioned so as to withdraw a gel obstruction from a depositing conduit, with a venturilike sucking action by passing water through the bypass line associated herewith, thereby depositing the withdrawn obstruction below the soil surface.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
279 words
An apparatus suitable for depositing a liquid below the surface of the earth comprising: a. a plurality of earthworking tools adapted for penetration of the surface of the earth; b. a first container adapted to hold a volume of water; c. a second container adapted to hold a volume of a liquid; d. a third container adapted to hold a volume of an inert gas under pressure; e. a first gas conduit with a shutoff valve therein connecting said third container with said first container at a point above the level of the liquid therein; f. a second gas conduit with a shutoff valve therein connecting said gas container with said second container at its upper portion; g. a first liquid conduit having a pair of shutoff valves therein connecting said first container with said second container at their lower portions; h. a liquid-dispensing conduit and a liquid bypass conduit mounted in pairs rearwardly on said earthworking tools having one end thereof terminating above and proximate the lower end of said earthworking tool, each of said dispensing conduits having a shutoff valve therein positioned above a constricting orifice therein and each of said bypass conduits having a shutoff valve therein, each of said pairs of dispensing bypass conduits being connected above the shutoff valve in the bypass conduit and between the shutoff valve and the orifice in the dispensing conduit, with one end of each of said dispensing conduits being connected above the shutoff valve therein with said first liquid conduit between said pair of shutoff valves therein, said tools and said containers being mounted to support means and adapted to be employed in conjunction with transport means therefor.
Claim 2
Independent Claim
279 words
An apparatus suitable for depositing a liquid below the surface of the earth comprising: a. a plurality of earthworking tools adapted for penetration of the surface of the earth; b. a first container adapted to hold a volume of water; c. a second container adapted to hold a volume of a liquid; d. a third container adapted to hold a volume of an inert gas under pressure; e. a first gas conduit with a shutoff valve therein connecting said third container with said first container at a point above the level of the liquid therein; f. a second gas conduit with a shutoff valve therein connecting said gas container with said second container at its upper portion; g. a first liquid conduit having a pair of shutoff valves therein connecting said first container with said second container at their lower portions; h. a liquid-dispensing conduit and a liquid bypass conduit mounted in pairs rearwardly on said earthworking tools having one end thereof terminating above and proximate the lower end of said earthworking tool, each of said dispensing conduits having a shutoff valve therein positioned above a constricting orifice therein and each of said bypass conduits having a shutoff valve therein, each of said pairs of dispensing bypass conduits being connected above the shutoff valve in the bypass conduit and between the shutoff valve and the orifice in the dispensing conduit, with one end of each of said dispensing conduits being connected above the shutoff valve therein with said first liquid conduit between said pair of shutoff valves therein, said tools and said containers being mounted to support means and adapted to be employed in conjunction with transport means therefor.
Claim 3
Dependent Claim
24 words
An apparatus according to claim 1 having bed-forming plates mounted to support means and positioned rearwardly and transversely to each of said earthworking tools.
Claim 4
Dependent Claim
38 words
Apparatus according to claim 2, having a pair of frustoconical bed-compacting rollers adjustably mounted to said plate support means rearwardly with respect to said bed-forming plates and having a cylindrical bed-forming roller mounted behind said frustoconical bed-compacting rollers.
Claim 5
Dependent Claim
23 words
Apparatus according to claim 1 having a second gas conduit with a shutoff valve therein connecting said third container with said liquid conduit.
