Abstract: An electrical submersible well pump assembly has shaft couplings. One of the couplings has a lower hub that rotates in unison with the motor shaft and an upper hub that rotates in unison with the pump shaft. A helical spring clutch engages both hubs when the motor shaft is being driven by the motor. Ceasing driving rotation of the motor shaft causes the spring clutch to disengage from the upper hub, enabling the pump shaft to rotate the upper hub without rotating the lower hub.

Abstract: A spring casing of a starter device of an internal combustion engine has a base body provided with a spring receptacle. A cover plate is provided to cover at least partially the spring receptacle. A connecting device is provided that connects the cover plate and the base body to each other. The connecting device secures the cover plate against a movement relative to the base body in a direction of a center axis of the spring casing. The connecting device only has a first part that is a component of the base body and a second part that is a component of the cover plate and has no further parts. A starter device with such a spring casing is provided.

Abstract: A specialty nut and specialty ratchet driver device used to start an internal combustion engine, each with an integrated one direction clutch, designed to be an attachment for a commercially available battery operated drill/driver gun. The specialty ratchet driver with an integrated one direction clutch is inserted into the driver receptacle of the socket placed over the nut on the crank shaft of the engine. One end of a drive shaft is inserted into the one direction clutch portion of the specialty ratchet driver device and the other end of the drive shaft is inserted into the chuck of a battery operated drill/driver gun. The torque of the drill/driver gun turns the crank shaft of the engine with sufficient force to initiate starting of the engine. The one direction clutch then allows the engine to turn faster than the drill/driver so as not to impede the engine start up.

Abstract: The present invention relates to the field of power tool devices, and more specifically, to a gasoline engine starting relay and a method of starting a gasoline engine. The small two-stroke or four-stroke gasoline engine starting relay comprises a housing, a power transfer end assembly, a power output end assembly, wherein the housing is provided with a device tube slot which has holes on both sides, namely a power transfer end hole and a power output end hole respectively, and which is mated with the power transfer end assembly and the power output end assembly. It can significantly improve and resolve the starting performance of a gasoline engine, and avoid difficulty in the hand-pulled starting so that the starting effect on a gasoline engine with large emissions for female workers, who may find difficulty in hand-pulled starting, is extremely obvious.

Abstract: A device designed to be a fixture for a commercially available battery operated drill/driver gun to start an internal combustion engine such as a model airplane engine by pressing the device onto the nose cone of the engine. The portion of the device which comes into contact with the nose cone of the engine is a cylinder connected to a shaft with a one way clutch. A rubber or silicone adapter is inserted into the cylinder attached to the shaft; the adaptor cone of the engine fits into the rubber or silicone adapter on the device.

Abstract: A lawn mower includes an internal combustion engine, a rotary tool driven by the internal combustion engine, an electric motor coupled to the internal combustion engine and configured to start the internal combustion engine, a receiving port mounted to the internal combustion engine, an energy storage device configured to be selectively inserted into and removed from the receiving port without tools, a first user interface, and a second user interface, wherein the electric motor starts the internal combustion engine upon actuation of the first user interface and the second user interface.

Abstract: In order to provide a handheld work machine that does not require expensive start circuitry for the critical start-up phase of the combustion engine, and in which nevertheless the required constant supply voltage for the engine is present in order to achieve optimum starting behavior, a handheld work machine is provided with at least one combustion engine which in operation requires a supply voltage, and with a voltage generator that supplies a generator voltage that depends on the rotary speed of the combustion engine, which generator voltage is used to generate the supply voltage, wherein the handheld work machine is electrically connected to an additional voltage source that prior to starting the combustion engine provides the required supply voltage that at this point in time is not yet present.

Abstract: The invention provides a system for providing power assisted starting for a variety of gasoline engine devices. In one embodiment, a device comprises a drill having a chuck, a hex shank socket extension coupled to the chuck and a tube. The tube has two dowel pins and the tube is coupled to the drill such that the tube encircles the hex shank socket extension. The tube is configured to couple to an anchor device configured around the hex nut of a bolt securing a flywheel of a gasoline engine.

Abstract: An electric starter apparatus and method with three-stage gearing and method for starting an internal combustion engine. The apparatus includes a starter assembly, a first gear, a second gear, a third gear, a fourth gear and an engine shaft. The starter assembly includes an electric starter motor and a starter motor shaft communicating with the starter motor. The starter motor shaft is rotatable in response to energizing of the starter motor. The first gear is attached to the starter motor shaft for rotation therewith. The second gear engages the first gear, the third gear engages the second gear, and the fourth gear engages the third gear. The fourth gear is attached to the engine shaft for communicating with an internal combustion engine. The engine is started by energizing the starter motor to rotate the starter motor shaft, the gears, and the engine shaft. The arrangement of gears enables the use of a low-torque/high-rpm electric starter motor in combination with a nickel-cadmium battery.

Abstract: A gasoline-fueled lawn mower has a pull rope that extends from the lawn mower engine and is attached to a pulley. An electrically powered starter motor is brought into engagement with the pulley, so that actuation of the starter motor causes the rope to be drawn out of the lawn mower engine, so as to start the engine. When the engine starts, the starter motor is disengaged, allowing the pull rope to be at least partly retracted into the engine. The pulley and the starter motor are preferably mounted on cross bars extending between portions of the lawn mower handle, the starter motor being mounted so as to slide along the cross bars. The invention also includes a kit for modifying a lawn mower to include a power-assisted starting mechanism.

Abstract: A tool fixture for enabling a mechanic to manually rotate an internal combustion engine which comprises an assembly of components which is placed inside a starter motor housing. The assembled combination of the starter motor housing with the present invention is then attached to the engine's bell housing where the starter motor would normally reside. The gear teeth of the engine flywheel engages a gear fixedly mounted on a first end of a rotatable shaft of the present invention. A nut is fixedly mounted on a second end of the rotatable shaft which is accessible to a mechanic's wrench so that torque may appropriately be applied to the rotatable shaft which accordingly permits the fly wheel to be rotated slowly to any desired position as may be required so as to facilitate for the tuning and other adjustment procedures to be performed upon the engine.

Abstract: A miniature-engine starter has a starter wheel (1) with a starter rim (2) that engages tangentially a flywheel rim (3) of a flywheel (4) of a miniature engine (5). The starter wheel is rotatable on a starter axle (9) that can be situated parallel to an axis of the flywheel and thereby starter-actuate the miniature engine. The starter axle is on a starter bracket (17) which can be hand-held or fastener-attached to an engine platform (6) to which the miniature engine is attached. The starter wheel has a transmission (7, 8, 13) to which a motorized rotator (22) is engaged for rotation while the starter rim is held firmly but removably against the flywheel for rotation to start the miniature engine. The starter rim can be rubberlike to engage grip indentations (19) or can have starter gear teeth (21) to mate with flywheel gear teeth (20).
