  • Patent number: 4108456
    Abstract: A lawn mower handle mounting wherein a mower has a handle attached thereto and the handle includes two end portions pivotally mounted to the mower. A projection extends on the mower adjacent the pivot axis of the handle and the handle can slide over the projection to be disposed therebelow and the handle is spring-biased to be retained underneath the projection. A rib extends underneath the projection at an angle to engage the upper edge of the handle, and a block extends below the handle so that the handle is secure and snug between the rib and the block, as urged thereagainst by the spring action mentioned. A pivot pin interconnects the handle and the mower and allows the handle to be sprung from underneath the projection and free thereof so that the handle can be pivoted upwardly relative to the mower, when desired.

  • Patent number: 4108120
    Abstract: A governor control for an internal combustion engine of the type wherein air is blown in the operation of the engine to move an air vane connected with the throttle plate for throttling the engine. An operator-controlled handle is movably mounted and interconnects with the air vane through a spring and a flexible cable, all for placing spring tension on the air vane to resist the blowing by the engine and thus govern the engine's speed. A movable stop member is operative on the handle and is spring urged so that the handle can be set in normal engine speed positions and thus cause the engine to run slow or fast, and the handle can also be set in an overriding and spring-urged position to cause the engine to run faster and the spring will automatically return the handle to the fast engine speed position when the operator releases the handle.
