Abstract
Abstract This invention relates to a power gate and lift means which is mountable on a conventional truck bed and operable to provide (1) a power gate means which is movable under hydraulic pressure from the closed to opened condition in order to readily empty grain and the like therefrom; and (2) a lift means mounted on the tail gate area of the truck bed operable under hydraulic pressure to raise and lower a lift member for loading and unloading various articles thereon. More particularly, this invention relates to a power gate means movable in an efficient manner from the locked to the unlocked and elevated condition for speed in unloading and a power lift means operable with various lift means in order to load drums, cattle, sheep, and the like on the truck bed in a most efficient and effective manner.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
190 words
A power gate and lift means mountable on a truck bed, comprising: a. a support means secured to said truck bed, b. gate means pivotally connEcted to said support means to enclose a rear area of said truck bed and movable from opened to closed positions, c. power means connected to said support means and said gate means to raise and lower said gate means, d. said gate means having a tail gate assembly pivotally connected to actuator arms, e. said actuator arms pivotally connected to said support means and said power means, f. said tail gate assembly having anchor pin members engagable with said truck bed when in the closed position to prevent lateral movement of said tail gate assembly, and g. said actuator arms of a J-shape having a long leg extended in a horizontal plane in the closed condition and a short leg extended downwardly from said long leg whereby the connection of said short leg to said tail gate assembly is located between the top and bottom portions of said tail gate assembly, thereby preventing rearward movement of said tail gate assembly in the closed condition.
Claim 2
Dependent Claim
190 words
A power gate and lift means mountable on a truck bed, comprising: a. a support means secured to said truck bed, b. gate means pivotally connEcted to said support means to enclose a rear area of said truck bed and movable from opened to closed positions, c. power means connected to said support means and said gate means to raise and lower said gate means, d. said gate means having a tail gate assembly pivotally connected to actuator arms, e. said actuator arms pivotally connected to said support means and said power means, f. said tail gate assembly having anchor pin members engagable with said truck bed when in the closed position to prevent lateral movement of said tail gate assembly, and g. said actuator arms of a J-shape having a long leg extended in a horizontal plane in the closed condition and a short leg extended downwardly from said long leg whereby the connection of said short leg to said tail gate assembly is located between the top and bottom portions of said tail gate assembly, thereby preventing rearward movement of said tail gate assembly in the closed condition.
Claim 3
Dependent Claim
80 words
A power gate and lift means as described in claim 1, wherein: a. a lower section of said tail gate assembly is pivotal upwardly relative to said connection to said short leg in the raised condition to permit flow of material therethrough under gravity; and b. an upper portion of said tail gate assembly first contacts top rearward portions of said truck bed on movement to the closed condition to immediately pivot said tail gate assembly to the closed condition.
Claim 4
Dependent Claim
52 words
A power gate and lift means as described in claim 1, wherein: a. said tail gate assembly having a main body with opposed, upright inwardly extended edge sections to enclose the rear area of said truck bed and prevent loss of material therefrom as serving a sealing function with said truck bed.
Claim 5
Dependent Claim
48 words
A power gate and lift means as described in claim 3, wherein: a. said tail gate assembly having opposed roller members secured to said edge sections; and b. said roller members mounted in upright guide rails of said truck bed for controlled vertical movement by said power means.
Claim 6
Dependent Claim
262 words
A power gate and lift means mountable on a truck bed, comprising: a. a support means secured to said truck bed, b. gate means pivotally connected to said support means to enclose a rear area of said truck bed and movable from opened to closed positions, c. power means connected to said support means and said gate means to raise and lower and gate means, d. said gate means having a tail gate assembly pivotally connected to actuator arms, e. said actuator arms pivotally connected to said support means and said power means, f. said tail gate assembly having anchor pin members engagable with said truck bed when in closed position to prevent lateral movement of said tail gate assembly, g. said actuator arms of a J-shape having a long leg extended in a horizontal plane in the closed condition and a short leg extended downwardly from said long leg whereby the connection of said short leg to said tail gate assembly prevents lateral movement of said tail gate assembly in the closed condition, h. said power means having a piston and cylinder assembly connected to said support means and to said tail gate assembly, i. a lower section of said tail gate assembly pivotal upwardly relative to said connection to short leg in the raised condition to permit flow of material therethrough under gravity, and j. an upper portion of said tail gate assembly to first contact top rearward portions of said truck bed on movement to the closed condition to immediately pivot said tail gate assembly to the closed condition.
Claim 7
Dependent Claim
262 words
A power gate and lift means mountable on a truck bed, comprising: a. a support means secured to said truck bed, b. gate means pivotally connected to said support means to enclose a rear area of said truck bed and movable from opened to closed positions, c. power means connected to said support means and said gate means to raise and lower and gate means, d. said gate means having a tail gate assembly pivotally connected to actuator arms, e. said actuator arms pivotally connected to said support means and said power means, f. said tail gate assembly having anchor pin members engagable with said truck bed when in closed position to prevent lateral movement of said tail gate assembly, g. said actuator arms of a J-shape having a long leg extended in a horizontal plane in the closed condition and a short leg extended downwardly from said long leg whereby the connection of said short leg to said tail gate assembly prevents lateral movement of said tail gate assembly in the closed condition, h. said power means having a piston and cylinder assembly connected to said support means and to said tail gate assembly, i. a lower section of said tail gate assembly pivotal upwardly relative to said connection to short leg in the raised condition to permit flow of material therethrough under gravity, and j. an upper portion of said tail gate assembly to first contact top rearward portions of said truck bed on movement to the closed condition to immediately pivot said tail gate assembly to the closed condition.
