Abstract
A rake system and method may include a framework, a chain, an elongated rail, a support arm, and an engagement feature. The elongated rail may be pivotably connected to the framework. The support arm may be connected to the elongated rail at a first point and may be pivotably connected to the framework at a second point. The engagement feature may be connected to the support arm and may be configured to engage the chain. The rake system may be configured to discard debris.
Claims28
A rake system, comprising:
- a framework;
- a chain configured to traverse over a vertical range;
- an elongated rail pivotably connected to a first support arm and a second support arm;
- the first support arm connected to the elongated rail at a first point and pivotably connected to the framework at a second point disposed within the vertical range of the chain;
- the second support arm connected to the elongated rail at a third point spaced from the first point and pivotally connected to the framework at a fourth point disposed within the vertical range of the chain and spaced from the second point;
- a guide device comprising a roller, guide, or a contour member connected to the elongated rail and configured to engage the chain;
- and
- wherein the rake system is configured to discard debris.

A rake system, comprising:
- a framework comprising a top and a bottom, the framework spanning a framework vertical range between the top and the bottom of the framework;
- a chain configured to traverse over a chain vertical range, the chain vertical range spanning a distance less than the framework vertical range;
- an elongated rail pivotably connected to a first support arm and a second support arm;
- the first support arm connected to the elongated rail at a first point and pivotably connected to the framework at a second point disposed within the chain vertical range;
- the second support arm connected to the elongated rail at a third point spaced from the first point and pivotally connected to the framework at a fourth point disposed within the chain vertical range and spaced from the second point;
- a guide device connected to the elongated rail and configured to engage the chain;
- and
- wherein the rake system is configured to remove debris from a waterway.

A rake system, comprising:
- a frame;
- a chain configured to traverse over a chain vertical range;
- a first upper support arm connected to an elongated rail at a first point and pivotably connected to the frame at a second point;
- the elongated rail is pivotably connected to the first upper support arm;
- a second lower support arm pivotably connected to the elongated rail at a third point and pivotally connected to the frame at a fourth point displaced from the second point, the second point and fourth point arranged vertically with respect to a ground level when the rake system is installed, the second and fourth points being disposed within the chain vertical range;
- and
- a guide device comprising a roller, a guide, or a contour member located at an end of the elongated rail, the guide device is operable to engage the chain;
- wherein the rake system is configured such that the chain is operable to move to a flexed position.
