BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a device for the propulsion of a tumbler body and, more particularly, to a device for the propulsion of a tumbler body in the shape of an oloid.
2. History of the Related Art
CH-patent 500 000 describes a device for the generation of a tumbling motion. This device consists of a body that Paul Schatz, in his book "Rhythmusforschung und Technik," (Stuttgart 1975), refers to as an "oloid." This oloid, according to CH-A1 500 000, is driven by a conveyor belt which carries the oloid. This drive was not very popular in practical applications, because it requires a perfectly shaped oloid and no slip during the rolling of the oloid. Guide rollers, which are commonly used on drum-shaped rolling elements, cannot be used with the shape of the oloid. Even though it has, much like a cylinder, a straight contact line on one plane, the angle of this contact line changes in an oscillatory manner with respect to the direction of travel. Therefore, the invention never became successful. This is not the case with the solution presented in CH-patent 216 760 in which a hollow body, executing a tumbling motion, is part of a half Bricard chain. This solution has been successful in the market employing various designs and different means of propulsion. But it has the tremendous disadvantage that prevents the construction of a mixer based on the oloid or inversion principle with a capacity of one or more cubic meters. This disadvantage is caused by the high mass forces occurring during operation that constantly change in size and direction. These mass forces require extremely large components and, thus, represent extreme challenges to the base of such a machine.
The purpose of this invention is the creation of a drive for an oloid body that overcomes these disadvantages and is also suited for oloids with large dimensions.
SUMMARY OF THE INVENTION
The present invention relates to a device for the propulsion of a tumbler body. More particularly, one aspect of the invention comprises a device for the propulsion of a tumbler body in the shape of an oloid characterized by a shaft attached to this tumbler body exhibiting the direction and position of its longitudinal axis. Means are provided to guide and drive the trace points of the axis of the shaft through two parallel planes on each side of the tumbler body and defining its direction of movement on oval paths, with the movements of the trace points of the axis of the shaft through the two planes in the same rotating direction but basically against each other. The tumbler body is also positioned on a passively driven base.
In another aspect, the above described invention includes the device described above wherein the means necessary to guide the trace points of the axis of the shaft with the two parallel planes on oval paths consist in the fact that an oval guiding rail is present in both planes and that this rail is connected to a frame by at least four spring attachments which allow for a vertical movement. A carriage is attached to each guiding rail that can travel along these guiding rails and each carriage consisting of a frame carrying at least two guiding wheels is responsible for the friction-type and positive connection with the guiding rail, and a rotary joint on the frame, whose rotary axis is perpendicular to the tangent at the guiding rail and lies in its plane with its rotary part being a plate rotating by means of a rotary joint carrying a crossbeam parallel to the direction of the tangent at the guiding rail. The invention is further characterized by the presence of a guiding element in which the shaft can execute longitudinal and rotary motions and that can be swivelled around the mentioned crossbeam at the plate. The dimensions of the guiding rail, carriage with rotary joint, plate, and guiding element are designed so that the trace points of the axis of the shaft describe the intended oval curve in the planes when the tumbler body is moved by its base. Each carriage is conne
