| 221 | Engine controller | US745754 | 1991-08-16 | US5113825A | 1992-05-19 | Keiichi Takahashi |
| An engine controller which is arranged to operate a governor through an actuator which is controllable either by an accelerator lever in an operator's station or by radio control. First and second levers are rotatably mounted on a shaft, and are biased respectively by a spring to turn in one direction. The first lever is connected to the governor by a wire in such a manner as to increase the engine speed when turned in a direction reverse to the biased direction. The second lever is connected to the accelerator lever by a second wire in such a manner as to rotate in the reverse direction when the accelerator lever is operated in the direction of acceleration. A pulley is mounted on the shaft, and a third lever is securely fixed to the pulley. The pulley is connected to the actuator by a third wire such that the pulley is rotated according to the rotation of the actuator. A rod is securely fixed to the first lever to transmit the reverse rotations of the second and third levers to the first lever. | ||||||
| 222 | Valve actuator differential worm planetary gear drive | US390551 | 1989-08-07 | US4994001A | 1991-02-19 | Ivan E. Wilkinson; Charles L. Hylton; R. Gregory Pence |
| A valve actuator differential worm planetary gear drive provides forward or reverse motion to a valve stem, from an input from either a motor-driven worm or a handwheel drive worm, by using a plurality of planet gears to send motion to the sun gear. If the preference is to have the motor drive the valve primarily, the manual worm stays locked and the motor worm acts as a planetary arm. When it is desired to move the valve by hand, the motor gear is fixed and rotation of the handwheel worm gear transmits the power through the ring gear and the planet gears to the drive sleeve. | ||||||
| 223 | Digitally incremented linear actuator | US303450 | 1989-01-27 | US4964311A | 1990-10-23 | Mathew G. Boissevain |
| A linear actuator having an actuator member driven in a linear direction by a lever mechanism pivotally coupled thereto which is in turn driven by a plurality of on/off linear drivers. Driving the linear drivers through varying stroke distances provides a sequence of discrete actuator steps. By providing an interconnected simple lever mechanism a discrete set of 2.sup.n steps may be provided for n drive positions and n on/off linear drivers. The linear actuator thus provides simple integration with a digital control system and precise positive discrete steps of linear actuation. | ||||||
| 224 | Trim linkage | US782863 | 1985-10-02 | US4649767A | 1987-03-17 | Dale Banas |
| A mechanical proportioning trim execution device in the general configuration of a four-bar linkage including input and output levers coupled by a connecting link, with the input lever having its length determined by a movable pivot automatically adjusted by a gear motor to produce the trim function. The movable pivot advances or retracts along a path which is highly skewed to the line of the input lever in a manner such that the path is perpendicular to the connecting link at zero input displacement for minimum trim effect and is parallel to the connecting link at full input displacement for maximum trim effect. | ||||||
| 225 | Push pull multiplier linkage | US667992 | 1984-11-05 | US4608880A | 1986-09-02 | Andrew Gahura; Graham M. Platt |
| A mechanical multiplier (25) in a fuel control for a gas turbine engine has a first track member (26) mounted for lateral movement and a first axially movable displacement member (34) connected to the first track member. A second track member (42) is mounted adjacent the first track member for pivoting movement about an axis (52). A follower assembly (54) operatively interconnects the track members and has rollers (120,122) respectively received in the tracks of the first and second track members. A second displacement member (55) is connected to the follower assembly for movement generally perpendicular to the direction of lateral movement of the first track member. The second displacement member is connected to the output piston (65) of a pressure transducer (66) which senses compressor discharge pressure; and the first displacement member is operatively connected to a fuel metering valve (100). The angular position of the second track member with respect to the first track member represents a set ratio (W/P) of fuel flow (W) to compressor discharge pressure (P). | ||||||
| 226 | Dual-rate control assembly | US500430 | 1983-06-02 | US4553448A | 1985-11-19 | Stephen A. Youngers; Robert G. Draney |
| An improved control assembly is disclosed which is particularly suited for embodiment as a so-called mono stick control for a material handling implement. The control assembly includes a lever support member adapted to be pivotally mounted on an associated implement, and which carries a first control lever adapted to pivot with respect to the support member about a first pivot axis. The support member further carries a second control lever which is adapted for pivotal movement about a second axis parallel to and spaced from the first axis. Notably, the second control lever is operatively interconnected with the first control lever such that relatively large angular movement of the second lever results in a relatively lesser angular movement of the first control lever, with the second lever then acting to prevent movement of the first lever back into its neutral position. By this arrangement, a device operatively connected for control with the first lever can be controlled at two rates, thus permitting normal control by manipulation of the first lever, and relatively fine control by manipulation of the second lever. | ||||||
| 227 | Rotary drive transmission mechanism especially for motor vehicles | US373271 | 1982-04-29 | US4499787A | 1985-02-19 | Rolf Leistner; Herbert Becker |
| An adjustment drive apparatus particularly for motor vehicles having coaxial rotatably supported driving and driven members with a helical spring which is braced against the inner circumferential surface of a hollow cylindrical element coaxial with these members operating to effect drive transmission therebetween. One of the members has a first claw or driver connection member rigidly affixed thereto, the claw member pressing against one of the ends of the helical spring to effect an extension or enlargement of the spring when relative rotation occurs between the spring and the claw member. The hollow cylindrical element within which the helical spring is located is affixed for rotation with the other of the driving and driven members. An auxiliary driving member is provided which, when activated, will cause the spring to be disengaged so that the driven member may be rotated through the auxiliary driving member. | ||||||
| 228 | Lever mechanism | US377215 | 1982-05-11 | US4478104A | 1984-10-23 | Ronald C. Page; Derek J. Smith |
| A lever mechanism (10) suitably, amongst other uses, for use in the control of tractor draft links (22) from a location remote from the tractor operators station.The lever mechanism includes an operating member (40), a support (43) relative to which said operating member is displaceable (Z), a lever (42) pivotally mounted on the support about a pivot axis (44) which is also translationally moveable (X), a first formation (56) on the lever, a second formation (57) on the operating member, and bias means (53) acting to translationally move the lever on its axis (44) away from the second formation (57) to hold the first and second formations (56,57) disengaged when the lever is released. The operating member is displaceable in a given direction (Z) relative to the support (43) by translational movement (X) of the lever (42) on its moveable axis (44) against the bias (53) to bring the first and second formations (56,57) into engagement followed by pivotting (Y) of the lever relative to the support with the first and second formations engaged.When used to control tractor draft links the lever mechanism forms part of the draft link control system and is connected with the remainder of the system via operating member (40). | ||||||
