Abstract
Abstract Vibratory thrust is generated by a rotating crankshaft and controlled orbital movement of a single weight pivoted to the crankpin of the crankshaft. As the crankshaft rotates the center of gravity of the weight moves back and forth on a vector through the crankshaft axis. The direction of the vector is adjustable within a substantial angular range about the crankshaft axis.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
146 words
A vibration generator comprising, a housing; a crankshaft having a journal and a crankpin within said housing; bearing means in said housing supporting said crankshaft journal for rotation on a horizontal axis; a weight member eccentrically connected with said crankpin in rotatable relation thereto; a pinion in axial alignment with said crankpin non-rotatably secured to said weight member; an internal ring gear in mesh with said pinion mounted in a rotatively fixed position within said housing coaxially with said crankshaft journal; a pair of circular collars non-rotatably connected, respectively, to opposite sides of said weight member in axial alignment with said crankpin; and a pair of annular guide tracks in cooperative engagement with said collars mounted in said housing coaxially with said crankshaft journal, the outside diameter of each of said collars being half as large as the inside diameter of the guide track cooperating therewith.
Claim 2
Dependent Claim
146 words
A vibration generator comprising, a housing; a crankshaft having a journal and a crankpin within said housing; bearing means in said housing supporting said crankshaft journal for rotation on a horizontal axis; a weight member eccentrically connected with said crankpin in rotatable relation thereto; a pinion in axial alignment with said crankpin non-rotatably secured to said weight member; an internal ring gear in mesh with said pinion mounted in a rotatively fixed position within said housing coaxially with said crankshaft journal; a pair of circular collars non-rotatably connected, respectively, to opposite sides of said weight member in axial alignment with said crankpin; and a pair of annular guide tracks in cooperative engagement with said collars mounted in said housing coaxially with said crankshaft journal, the outside diameter of each of said collars being half as large as the inside diameter of the guide track cooperating therewith.
Claim 3
Dependent Claim
126 words
A vibration generator comprising a housing; a crank member having a journal portion mounted in an end wall of said housing for rotation on a horizontal axis and a crank pin within said housing spaced radially from the axis of said journal portion; a weight member eccentrically connected with said crank pin in rotatable relation thereto; an internal ring gear mounted in said housing coaxially with said journal portion of said crank member; peripheral load transmitting means securing said ring gear against rotation relative to said housing; a pinion non-rotatably connected with said weight member coaxially with said crank pin and in mesh with said ring gear; and radial load transmitting means operatively interposed between said weight member and said housing independently of said crank member.
Claim 4
Dependent Claim
126 words
A vibration generator comprising a housing; a crank member having a journal portion mounted in an end wall of said housing for rotation on a horizontal axis and a crank pin within said housing spaced radially from the axis of said journal portion; a weight member eccentrically connected with said crank pin in rotatable relation thereto; an internal ring gear mounted in said housing coaxially with said journal portion of said crank member; peripheral load transmitting means securing said ring gear against rotation relative to said housing; a pinion non-rotatably connected with said weight member coaxially with said crank pin and in mesh with said ring gear; and radial load transmitting means operatively interposed between said weight member and said housing independently of said crank member.
Claim 5
Dependent Claim
34 words
A vibration generator as set forth in claim 2 wherein said peripheral load transmitting means are adjustable so as to selectively secure said ring gear in different rotatively adjusted positions relative to said housing.
