Abstract
Abstract The invention comprises a substantially hook-like materials gate including a moldboard wall, a collector wall and materials wall disposed distally at one of the terminal ends on the materials engaging side of a moldboard of a commonly known motor patrol, and a materials diverter carried between the moldboard and the moldboard wall of the materials gate. The materials gate may be operable to be selectively raised and lowered relative to the moldboard of the motor patrol in response to fluid or air under pressure supplied from a suitable source by means such as hydraulic or pneumatic cylinders.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
In earth moving apparatus including a moldboard operable at an angle with respect to the direction of travel of said apparatus and having a concave earth engaging surface and earth cutting blades, the combination of a substantially hook-like gate portion having a substantially flat moldboard wall mounted on said earth engaging surface distally from one of the terminal ends of said earth moving apparatus, an upstanding collector wall issuing outwardly at an angle from said moldboard wall, an upstanding materials retaining wall issuing from said collector wall and being disposed substantially rectilinearly with the direction of travel of said earth moving apparatus; an upstanding materials diverter at the terminal end of said gate portion opposite said materials retaining wall being suitably fastened to said moldboard, said materials diverter including an outwardly projecting upstanding wall having a terminal edge conforming to and contiguous with said concave earth engaging surface of said moldboard of said earth moving apparatus; and means mounting said gate portion to said moldboard of said earth moving apparatus.
Claim 2
Dependent Claim
170 words
In earth moving apparatus including a moldboard operable at an angle with respect to the direction of travel of said apparatus and having a concave earth engaging surface and earth cutting blades, the combination of a substantially hook-like gate portion having a substantially flat moldboard wall mounted on said earth engaging surface distally from one of the terminal ends of said earth moving apparatus, an upstanding collector wall issuing outwardly at an angle from said moldboard wall, an upstanding materials retaining wall issuing from said collector wall and being disposed substantially rectilinearly with the direction of travel of said earth moving apparatus; an upstanding materials diverter at the terminal end of said gate portion opposite said materials retaining wall being suitably fastened to said moldboard, said materials diverter including an outwardly projecting upstanding wall having a terminal edge conforming to and contiguous with said concave earth engaging surface of said moldboard of said earth moving apparatus; and means mounting said gate portion to said moldboard of said earth moving apparatus.
Claim 3
Dependent Claim
170 words
In earth moving apparatus including a moldboard operable at an angle with respect to the direction of travel of said apparatus and having a concave earth engaging surface and earth cutting blades, the combination of a substantially hook-like gate portion having a substantially flat moldboard wall mounted on said earth engaging surface distally from one of the terminal ends of said earth moving apparatus, an upstanding collector wall issuing outwardly at an angle from said moldboard wall, an upstanding materials retaining wall issuing from said collector wall and being disposed substantially rectilinearly with the direction of travel of said earth moving apparatus; an upstanding materials diverter at the terminal end of said gate portion opposite said materials retaining wall being suitably fastened to said moldboard, said materials diverter including an outwardly projecting upstanding wall having a terminal edge conforming to and contiguous with said concave earth engaging surface of said moldboard of said earth moving apparatus; and means mounting said gate portion to said moldboard of said earth moving apparatus.
Claim 4
Dependent Claim
170 words
In earth moving apparatus including a moldboard operable at an angle with respect to the direction of travel of said apparatus and having a concave earth engaging surface and earth cutting blades, the combination of a substantially hook-like gate portion having a substantially flat moldboard wall mounted on said earth engaging surface distally from one of the terminal ends of said earth moving apparatus, an upstanding collector wall issuing outwardly at an angle from said moldboard wall, an upstanding materials retaining wall issuing from said collector wall and being disposed substantially rectilinearly with the direction of travel of said earth moving apparatus; an upstanding materials diverter at the terminal end of said gate portion opposite said materials retaining wall being suitably fastened to said moldboard, said materials diverter including an outwardly projecting upstanding wall having a terminal edge conforming to and contiguous with said concave earth engaging surface of said moldboard of said earth moving apparatus; and means mounting said gate portion to said moldboard of said earth moving apparatus.
Claim 5
Dependent Claim
44 words
The apparatus of claim 1 in which said diverter includes an upstanding deflector portion issuing rearwardly at an angle from said diverter; said moldboard wall of said gate portion being slidably carried between said diverter portion and said moldboard of said earth moving apparatus.
Claim 6
Dependent Claim
20 words
The apparatus of claim 2 including means operable to selectively raise and lower said gate portion relative to said moldboard.
