US Patent:

6779415, Aug 24, 2004

Filed:

Oct 10, 2001

Appl. No.:

09/975647

Inventors:

Laird B. Gogins - Salt Lake City UT 84103

International Classification:

F16H 2910

US Classification:

74124, 741255

Abstract:

A constant power mechanical transmission with seamless, ripple free, infinitely variable torque multiplying outputs comprises an input shaft and an output shaft. The input shaft is coupled to a pair of oscillating levers whereby rotation of the input shaft causes oscillation of the oscillating levers in opposite directions. The oscillating levers are linked to the output shaft with one-way clutches in order to cause rotation of the shaft upon movement of the oscillating levers. The rotational speed of the output shaft can be infinitely varied by changing the throw of the oscillating levers.

Appl. No.:

5/751952

Inventors:

Laird B. Gogins - Salt Lake City UT

Assignee:

Power-Matic Corporation - Salt Lake City UT

International Classification:

F16H 3502

US Classification:

74393

Abstract:

The variable speed transmission includes a power input drive shaft and a variable throw crank having a zero throw position aligned with the input shaft. The variable throw crank is coupled to the input shaft for rotation therewith and its eccentricity with respect to the axis of rotation of the input shaft can be varied. A control plate, also referred to as a master link, is rotatably mounted on the crank and a plurality of clutches having input and output shafts are operatively connected to the control plate through a plurality of pitman type links, whereby the control plate oscillates the input shafts of the clutches upon rotation of the power input shaft and variable throw crank of the transmission. The outputs of the clutches are connected to an output shaft for the transmission. By varying the throw of the variable throw crank the ratio between the rotary speed of the output shaft can be infinitely adjusted from zero to a maximum ratio determined by the maximum eccentricity of the variable throw crank with respect to the axis of rotation of the input shaft.

Appl. No.:

7/930928

Inventors:

Laird B. Gogins - Salt Lake City UT

International Classification:

F16H 2904

US Classification:

74117

Abstract:

A transmission for providing continuously variable speed and torque comprises a housing, an input shaft, a system of variable throw eccentrics, control means for changing eccentric throw of the variable throw eccentrics, connecting links for receiving eccentric throw from the system of variable throw eccentrics and transmitting it as reciprocal motion and removing ripple from the output, one-way clutches for receiving reciprocal motion from connecting links and transmitting it as rotational motion, and an output shaft. The control means comprise a control shaft rotatably disposed around the input shaft so that both shafts have the same rotational axis and with a fork fixed to the control shaft, a pin fixed at one end to an eccentric and engaged between the prongs of the fork, and means for rotating the control shaft with respect to the input shaft, thus changing the eccentric throw and the transmission ratio. Reversible and nonreversible hydraulic one-way clutches, means for reversing rotation of the output shaft, and means for compression braking are also within the scope of the invention.

Laird B. Gogins - Salt Lake City UT

Assignee:

Utah Transmission Corporation - Salt Lake City UT

International Classification:

F16H 2904
F16H 2910

US Classification:

74117

Abstract:

A variable transmission having an input shaft, a lobed cam slidably splined on said shaft, and a plurality of pivotedly mounted cam followers which mechanically engage the cam is disclosed. The cam follwers are connected to an output shaft through intermediation of a one-way clutch mechanism. Each cam follower includes a steerable contact member whose orientation may be modified to induce a coaxially directioned, displacing force on the cam. The displacement of the cam effects a shifting of the transmission ratio.

International Classification:

F03D 504
H02P 904

US Classification:

290 55

Abstract:

Apparatus to convert wind energy into mechanical and electrical energy including a variable pitch air-foil supported by tension guy wires on a wheeled structure constrained to move upon a continuous track. The structure includes electrical generators powered by the rotation of the structure's wheels to convert movement of the structure into electrical energy. The air-foil is supported upright on the wheeled structure, which is designed to resist upward, downward and sideways forces, to capture wind energy at a higher elevation above the ground where winds blow stronger.
