Abstract
Abstract A lever gudgeon and connector block between earth-contacting mechanism and the lifting arms of a prime mover permits the earth-contacting mechanism to be pivoted at different angles both horizontally and vertically to such lifting arms for performing various operations without moving the prime mover, which block extends between the lifting arms providing a lever with extensive mechanical advantage and, also, permits horizontal, diagonal, and vertical pivoting of the earth-contacting equipment as attachments to the lifting arms without binding or impingement thereof.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
189 words
An assembly with a pair of lifter arms of a prime mover comprising: a. connector block means includes a reinforced rectangular tube having its ends rigidly secured adjacent the ends of said lifter arms; b. a triangular tube rigidly secured to an outward facing side of said rectangular tube inclusive of depending horizontal pivot means for a lever gudgeon extending forwardly of said triangular tube to mate with said lever gudgeon And arranged with said horizontal pivot means in a substantially parallel position to the ground when said lifter arms are resting on or near the ground; c. a lever gudgeon mounted on said horizontal pivot means, said lever gudgeon including vertical pivot means for supporting earth-contacting means; d. first actuator means pivotally connected between said lever gudgeon and said lifter arms for pivoting said lever gudgeon about said horizontal pivot means thereby pivoting said vertical pivot means and a carried earth-contacting means through a vertically disposed arc; e. second actuating means mounted between said earth-contacting means and said lifter arms for moving carried earth-contacting means through a horizontal arc; and f. earth-contacting means carried by said lever gudgeon.

An assembly with a pair of lifter arms of a prime mover comprising: a. connector block means includes a reinforced rectangular tube having its ends rigidly secured adjacent the ends of said lifter arms; b. a triangular tube rigidly secured to an outward facing side of said rectangular tube inclusive of depending horizontal pivot means for a lever gudgeon extending forwardly of said triangular tube to mate with said lever gudgeon And arranged with said horizontal pivot means in a substantially parallel position to the ground when said lifter arms are resting on or near the ground; c. a lever gudgeon mounted on said horizontal pivot means, said lever gudgeon including vertical pivot means for supporting earth-contacting means; d. first actuator means pivotally connected between said lever gudgeon and said lifter arms for pivoting said lever gudgeon about said horizontal pivot means thereby pivoting said vertical pivot means and a carried earth-contacting means through a vertically disposed arc; e. second actuating means mounted between said earth-contacting means and said lifter arms for moving carried earth-contacting means through a horizontal arc; and f. earth-contacting means carried by said lever gudgeon.
Claim 3
Dependent Claim
18 words
An assembly according to claim 1 wherein said horizontal pivot means is a pair of spaced-apart apertured plates.
Claim 4
Dependent Claim
266 words
An assembly with a pair of lifter arms of a prime mover comprising: a. connector block means rigidly secured adjacent the ends of said lifter arms inclusive of horizontal pivot means for a lever gudgeon extending forwardly of said connector block means, said connector block means arranged with said horizontal pivot means in a substantially parallel position to the ground when said lifter arms are resting on or near the ground; b. a lever gudgeon mounted on said horizontal pivot means, said lever gudgeon including vertical pivot means for supporting earth-contacting means for pivotal movement about said vertical pivot means; c. idler arms pivotally mounted on said connector block; d. a pair of pivot levers pivotally mounted on said lifter arms; e. a connecting rod assembly connected between said idler arms on said connector block and said pivot levers; f. first actuator means pivotally connected between said lever gudgeon and said idler arms on said connector block for pivoting said lever gudgeon about said horizontal pivot means thereby pivoting said vertical pivot means and carried earth contacting means through a vertical arc; g. second actuating means mounted between said earth-contacting means and said prime mover lifter arms for moving carried earth-contacting means through a horizontal arc; and h. earth-contacting means carried by said lever gudgeon on said vertical pivot means so that said earth-contacting means swings through a generally horizontal arc and so that the connected combination of pivot levers, lifter arms, idler arms and connecting rod provide a pantograph for leveling said lever gudgeon and carried earth-contacting means on raising and lowering said lifter arms.
