Abstract
Abstract An improved vibrodriver for sinking a vertically elongated element of substantially uniform horizontal cross-section into or extracting such an element from the ground. The element is one of a plurality of like elements arranged side-by-side along a straight or curved line. The vibrodriver includes at least one pair of eccentrics with each eccentric or a portion thereof situated on a different side of the element. The vibrodriver has a waist which is narrower than the width of an element along the line; beyond the waist and toward its lateral ends the vibrodriver has at least one portion of each side thereof which is wider than the width of an element, thereby enabling the vibrodriver to be of relatively short horizontal length perpendicular to said line and yet to exert a substantial vertical vibratory force during the sinking or extraction of an element juxtaposed to at least one other element.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
193 words
In combination, a vibrodriver for sinking or extracting a vertically elongated element of substantially uniform horizontal cross-section into or from the ground, said element being one of plural such elements arrayed in a line, said vibrodriver comprising at least three parallel eccentrics, means mounting said eccentrics for rotation about horizontal axes, at least two eccentrics or portion thereof being situated on a different sides of said element, means releasably clamping said vibrodriver on said element, so that said element is a clamped element, and means to rotate said eccentrics, whereby said clamped element is vibratorily sunk into or extracted from the ground, said clamped element having a maximum width along said line of elements, said at least two eccentrics or portion thereof having enlarged effective width dimensions exceeding the corresponding effective width dimension of a third of said eccentrics, said enlarged effective width dimensions being accommodated at zones spaced laterally from the clamped element, said vibrodriver being narrower than said clamped element at the zone adjacent said clamped element so that the vibrodriver has increased power due to the enlarged effective width dimensions yet will be clear of elements adjacent the clamped element.
Claim 2
Dependent Claim
193 words
In combination, a vibrodriver for sinking or extracting a vertically elongated element of substantially uniform horizontal cross-section into or from the ground, said element being one of plural such elements arrayed in a line, said vibrodriver comprising at least three parallel eccentrics, means mounting said eccentrics for rotation about horizontal axes, at least two eccentrics or portion thereof being situated on a different sides of said element, means releasably clamping said vibrodriver on said element, so that said element is a clamped element, and means to rotate said eccentrics, whereby said clamped element is vibratorily sunk into or extracted from the ground, said clamped element having a maximum width along said line of elements, said at least two eccentrics or portion thereof having enlarged effective width dimensions exceeding the corresponding effective width dimension of a third of said eccentrics, said enlarged effective width dimensions being accommodated at zones spaced laterally from the clamped element, said vibrodriver being narrower than said clamped element at the zone adjacent said clamped element so that the vibrodriver has increased power due to the enlarged effective width dimensions yet will be clear of elements adjacent the clamped element.
Claim 3
Dependent Claim
41 words
The combination of claim 1, in which the axes of rotation of said plurality of eccentrics are parallel with said line, and in which a pair of outer eccentrics is provided that are longer than the width of the clamped element.
Claim 4
Dependent Claim
22 words
The combination of claim 2, in which each of the two outer eccentrics is composed of a plurality of coaxial separate sections.
Claim 5
Dependent Claim
46 words
The combination of claim 3, in which a pair of inner eccentrics is provided and in which each of the separate sections of the outer eccentrics are substantially the same as the inner eccentrics, the inner eccentrics being confined within the width of the clamped element.
Claim 6
Dependent Claim
47 words
The combination of claim 3, in which each of the separate sections is each mounted on a different sleeve, the sleeves of the different sections of an outer eccentric being synchronized and aligned by a solid shaft which extends through and rotates with all of the sleeves.
Claim 7
Dependent Claim
26 words
The combination of claim 5, in which the sleeves are internally axially grooved, and the solid shaft has an external axial projection received in said groove.
Claim 8
Dependent Claim
46 words
The combination of claim 1, in which the axes of rotation of the eccentrics are perpendicular to said line and the effective diameters of rotation of the at least two eccentrics at zones spaced from said line are greater than the width of the clamped element.
Claim 9
Dependent Claim
28 words
The combination of claim 7, in which the eccentrics at least two have outer parts with effective diameters of rotation greater than the width of the clamped element.
