US Patent:

50404539, Aug 20, 1991

Filed:

Sep 23, 1986

Appl. No.:

6/910626

Inventors:

Fred Eicher - Prospect KY
Charles F. Evans - Louisville KY

Assignee:

Turn Act Inc. - Jeffersontown KY

International Classification:

F01C 900

US Classification:

92122

Abstract:

The present invention provides housing member for a rotary fluid powered actuator including a cylindrical housing member having an opening in at least one end, a head member received on each open end of the housing where each head has a central aperture in generally aligned relation with the longitudinal axis of the housing, a shaft member to extend through the central aperture for rotation therein and journal means to journal the shaft in the housing adjacent each end thereof and a vane member to extend outwardly from the shaft member for rotation therewith in response to fluid pressure in the housing where the housing member includes at least one stator member, integral therewith extending radially inwardly from the sidewall of the housing and adapted to receive a seal member to provide a seal between the termination of the stator and the shaft and members extending along a portion of the length of the housing to define bolt passages, and bolt members to be received in the bolt passage where the bolt members contact the surface of the bolt passage and connect the head to the body at the end opposed to the open end.

Turn Act, Inc. - Louisville KY

International Classification:

F16D 7100

US Classification:

192143

Abstract:

A rotary actuator and a linear actuator are combined to provide an output shaft with independent linear and rotary motion. The linear actuator causes the rotary actuator to move linearly, and there is a guide which restricts the movement of the rotary actuator to linear motion and a bearing which receives the output shaft of the rotary actuator to prevent orbiting and deflection of the rotary output shaft.

Inventors:

Fred C. Eicher - Prospect KY
Charles F. Evans - Louisville KY
Gary M. Rumrill - Louisville KY

International Classification:

F16D 7100

US Classification:

192143

Abstract:

A multi directional actuator capable of moving a shaft in at least two directions independently including one linear and one rotary movement. A base plate is provided to receive a first actuator having a linearly moving shaft which is extended from and retracted into the actuator. A second actuator is connected for movement by the first actuator and where the second actuator operates an output shaft which is selectively rotated through a portion of an arc. A guide arrangement is provided to direct movement of the second actuator by the first actuator and to journal the shaft of the second actuator to prevent orbiting and deflection of the shaft of the second actuator. Limit switches can be provided to indicate end of the stroke of the linear and rotary actuators and the first and second actuators can be separated to allow use of limit stops to limit rotation of the shaft of the second actuator.

Assignee:

Turn-Act, Inc. - Louisville KY

International Classification:

B66C 110

US Classification:

294104

Abstract:

A rotary clamping device includes a rotary actuator and an L-shaped base, with a gripper device mounted on the output shaft of the rotary actuator. The construction is very simple and lightweight, so that, in the preferred embodiment, it is made up primarily of four extruded parts in addition to the actuator.

Appl. No.:

6/235533

Inventors:

Fred C. Eicher - Louisville KY
Charles F. Evans - LaGrange KY

International Classification:

F01C 900

US Classification:

92122

Abstract:

An oscillatory fluid powered motor includes a cylindrical body closed at its opposite ends by head members to define a chamber. Each head member has a central opening in aligned relationship with the longitudinal axis of the cylindrical body for receiving the opposite ends of a shaft. At least one vane is structurally associated with the shaft for rotation therewith, and extends radially of the cylindrical housing from the shaft. At least one stationary stator is attached to the interior wall of the cylindrical housing and extends radially of the housing. The cylinder heads include a bearing surface surrounding the central openings, and a ring seal concentrically disposed with and radially spaced from the central openings. The vane has a peripheral seal which sealingly contacts the bearing surface of each cylinder head, the interior wall surface of the cylindrical body and a portion of each ring seal. Similarly, the stator has a peripheral seal which sealingly contacts the bearing surface of each cylinder head, the peripheral surface of the shaft, and a portion of each ring seal.

Abstract:

An elongate elastomeric seal member including a first portion to be partially received in an elongate groove of a selected element where the groove has opposite sides and a base connecting the sides and a second portion extending outwardly from the opposite edges of the groove to sealably engage a sealing surface adjacent the element where fluid pressure is selectively applied to at least one side of the seal and where the seal, in cross section, includes a central body with first and second spaced feet extending outwardly therefrom to be received in the groove and engage the sides and base of the groove and third and fourth feet extending outwardly from the central element to slidably engage the sealing surface wherein fluid can be applied to at least one of the third and fourth feet to urge one of said third and fourth feet to sealing relation with said sealing surface.
