Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
170 words
Sewage disposal apparatus comprising: a main frame adapted to be positioned at a selected level above the surface of the ground; at least one vertically elongate and laterally narrow shank secured to and depending from the frame and adapted to penetrate the ground to a selected depth; a plow member secured to the lower end of the shank, including an axially elongate foot of substantially greater width than the shank to form a disposal tunnel beneath the surface of the ground; controllably adjustable power operated servo means to vary the cross sectional area of the foot during operation of the apparatus to vary the cross sectional area of the tunnel formed by the plow member; the shank including means defining a downwardly extending sewage discharge flow path from the vicinity of the frame to the vicinity of the plow member; and a dispensing port at the lower end of the flow path to discharge sewage into the tunnel, and a supply manifold at the upper end of the flow path.
Claim 2
Dependent Claim
170 words
Sewage disposal apparatus comprising: a main frame adapted to be positioned at a selected level above the surface of the ground; at least one vertically elongate and laterally narrow shank secured to and depending from the frame and adapted to penetrate the ground to a selected depth; a plow member secured to the lower end of the shank, including an axially elongate foot of substantially greater width than the shank to form a disposal tunnel beneath the surface of the ground; controllably adjustable power operated servo means to vary the cross sectional area of the foot during operation of the apparatus to vary the cross sectional area of the tunnel formed by the plow member; the shank including means defining a downwardly extending sewage discharge flow path from the vicinity of the frame to the vicinity of the plow member; and a dispensing port at the lower end of the flow path to discharge sewage into the tunnel, and a supply manifold at the upper end of the flow path.
Claim 3
Dependent Claim
52 words
Apparatus as claimed in claim 1 wherein: the foot includes movable members adapted to be displaced laterally in opposite directions to increase the effective cross sectional area of the foot and correspondingly enlarge the tunnel formed by the plow member; and power operated means to control the lateral displacement of the members.
Claim 4
Dependent Claim
48 words
Apparatus as claimed in claim 2 wherein: the movable members comprise wings pivotally mounted at their forward ends to the side walls of the foot to swing laterally to rearwardly divergent positions; and the power operated means is controllable to vary the degree of divergence of the wings.
Claim 5
Dependent Claim
42 words
Apparatus as claimed in claim 3 wherein: the foot has side walls that diverge downward and the wings swing upward as well as laterally to increase the down load on the plow member and assist in holding it at the desired depth.
Claim 6
Dependent Claim
33 words
Apparatus as claimed in claim 2 wherein: the power operated means comprises an expansible hydraulic servo motor extending transversely between the members and connected to both of them to force them angularly apart.
Claim 7
Dependent Claim
52 words
Apparatus as claimed in claim 5 wherein: a hydraulic power pack is mounted on the frame; and a hydraulic conduit is connected at its upper end to the power pack and extends downward within the confines of the shank with its lower end connected to the servo motor to supply fluid thereto.
Claim 8
Dependent Claim
52 words
Apparatus as claimed in claim 2 wherein: the movable members are provided at their inner sides with cam followers arranged in opposing relation; a cam is provided to be forced between the cam followers to displace the members; and the power operated means is connected to the cam to cause its movement.
Claim 9
Dependent Claim
44 words
Apparatus as claimed in claim 7 wherein: the power operated means includes a hydraulic servo motor mounted on the frame and a generally vertically extending actuator rod connected at its upper end to the servo motor and at its lower end to the cAm.
Claim 10
Dependent Claim
67 words
Apparatus as claimed in claim 2 wherein: a supply conduit is flow-connected to the manifold and to a continuous source of supply; pumping means is incorporated in the supply conduit to produce continuous flow; and a flushing conduit is flow-connected to the manifold and adapted to be connected to a source of high pressure water for flushing out the manifold and the discharge flow path on occasion.
Claim 11
Dependent Claim
130 words
Apparatus as claimed in claim 1 wherein: a tractor is provided to pull the shank and plow member forward through the ground; upper and lower links are provided and are pivotally connected at their forward portions to the tractor and at their rearward portions to a forward section of the main frame, the forward and rearward pivotal connections having substantially the same vertical spacing to define a parallelogram support for the main frame and maintain it in substantially a constant attitude at all elevations; and power operated means is provided on the tractor and connected to at least one of the links to raise and lower the rearward portion of the parallelogram support together with the main frame attached thereto while maintaining the attitude of the main frame substantially constant.
Claim 12
Dependent Claim
62 words
Apparatus as claimed in claim 10 wherein: a roller is vertically movably mounted on the rearward end of the main frame; and power operated means is mounted on the main frame and connected to the roller to vary its elevation with respect to the main frame and maintain it in pressural contact with the ground at all elevations of the main frame.
