| 41 | Load sensing gearbox | US365816 | 1989-06-14 | US4979603A | 1990-12-25 | Graham Wheatland |
| A universal load sensing gearbox integrating a safety mechanism for use, for instance, with motor driven closures, such as garage doors, barriers and gates, includes a housing which encases a worm slidably mounted on an input shaft and adapted for rotation therewith. The input shaft is connected with the motor driving the closure. The worm is engaged with a worm gear which is mounted on an output shaft which is connected with the closure. Dished washers are provided generally around the input shaft at both ends of the worm to urge the worm in a central meshed engagement with the worm gear. A motion transmission device is provided on the worm and is adapted to slide therewith to detect a longitudinal movement thereof and to transmit this movement to an actuating device which is adapted to stop and/or reverse the motor. Therefore, sufficient resistance to the rotation of the output shaft resulting, for example, from the closure encountering an object pressure, causes the worm to be displaced along the input shaft against the dished washers along with the transmission device. A sufficient movement of the transmission device causes the actuating device to trip a limit switch which triggers the stoppage and/or reversing of the motor. The load sensing gearbox is also intended for agricultural applications using reducing gearboxes, for actuating aircraft wing flaps, for conveyer belts, etc. | ||||||
| 42 | Overload protection | US887066 | 1986-07-17 | US4763768A | 1988-08-16 | Heinz Flaig; Heinz Hasselmann |
| A bi-directionally effective overload protection device for a rotation machine part includes two coaxially arranged, mutually juxtaposed ring discs frictionally connected to a machine; a gear disc with outer gearing and inwardly directed flange means circumscribes the ring discs; a plurality of springs hold said gear disc normally in particular position in relation to the ring discs, permitting the gear disc to rotate relative to the ring discs upon occurrence of an overload in either directional rotation; a dual switching ring having an inner and an outer ring portion is connected to the second ring disc through resilient bar or leaf spring portions of the switching ring; actuator ramps on the outer and inner ring portions cooperate with axially extending cams on the gear disc so that either the inner or the outer ring is axially shifted on overload in one or the other direction; switches are arranged in relation to the inner and outer ring portion for being actuated by the particular one that is axially shifted on occurrence of overload. | ||||||
| 43 | Rotation paddle bin level indicator | US849410 | 1977-11-07 | US4147906A | 1979-04-03 | Walter E. Levine |
| Apparatus for indicating the level of flowable material in a storage bin comprising a motor rotatably suspended by a spring within a protective enclosure and a drive shaft coupled by a ball-and-detent clutch to a paddle disposed within the bin to engage material therein. When the material reaches the level of the paddle, the drag on the paddle causes the motor to rotate eccentrically within the enclosure and thereby to activate switches disposed within the enclosure radially of the motor housing. A spring returns the motor to the switch-deactivated position when the material level decreases and the consequent drag is removed from the paddle. | ||||||
| 44 | Material level indicator sensor | US38060873 | 1973-07-19 | US3818159A | 1974-06-18 | EVANS A; RANDOLPH C |
| A level sensing apparatus of the kind comprising a sensing switch actuated by a rotating paddle, with a cam drive connection between the drive motor and the sensing paddle which protects the drive motor from stalling or jamming in either normal or abnormal operation of the level sensing apparatus; the cam drive connection allows continuing unobstructed rotation of the drive motor shaft, when the sensing paddle is blocked, in the event of a failure of the sensing switch.

| 45 | Overload indicator | US3718792D | 1972-05-12 | US3718792A | 1973-02-27 | STAGNER J |
| An overload indicator for a cargo handling vehicle, such as a truck, trailer, or the like, having a chassis mounting a cargo receiver and supported on wheel axles by springs which yield under the cargo weight with resultant lowering of the chassis toward the axles. The indicator has two separate parts to be attached to one axle and the chassis, respectively, in such a way that the chassis part lowers into contact with the axle part to actuate an overload signal upon loading of the vehicle to a predetermined cargo weight. The indicator is adjustable to vary the cargo weight at which the overload signal is actuated and is designated to avoid damage to the indicator in the event of deflection of the vehicle springs beyond the point at which the chassis part initially engages the axle part due to continued loading of the vehicle or bouncing of the vehicle chassis and axle in travel.

| 60 | Emergency stop system of a hybrid excavator | JP2013520627 | 2010-07-21 | JP2013536333A | 2013-09-19 | ジユン キム; ウィチョル キム; ドンウク チェ |
| An emergency stop system for a hybrid excavator is provided, which includes an emergency switch and an emergency stop unit. In a normal operation state, a power supply that is applied from a power supply unit is provided to a hybrid controller and an engine controller, while when the emergency switch is pressed, the input power supply is intercepted to effectively stop the operation of the hybrid system in the case where equipment abnormality or an emergency situation occurs. Also, when the emergency switch is pressed, the power supply is applied to an emergency alarm unit and an energy discharge unit to notify an operator and neighboring persons of the equipment abnormality and emergency situation occurrence, and a hybrid power source vanishes completely. | ||||||
