Patent number: 7713111Abstract: A device for supplying water to a cutting wheel of a hand-held cut-off machine has a water-conducting line and a valve arrangement arranged in the line. The valve arrangement has a shut-off valve for controlling the water flow flowing through the line. The shut-off valve is actuated as a function of an operating signal of the cut-off machine such that in operation of the cut-off machine the water flow through the line is released by the shut-off valve. The shut-off valve interrupts the water flow through the line when the operating signal is absent.Type: GrantFiled: January 13, 2006Date of Patent: May 11, 2010Assignee: Andreas Stihl AG & Co.

Patent number: 7591378Abstract: A manually guided apparatus for collecting objects, especially fruits and nuts, including a pick-up drum rotatably mounted in the drum chamber of a housing. The drum is disposed approximately transverse to the direction of operation, and is rotationally driven by a drive unit. The housing has a wall section extending over the width of the drum approximately at the level of the outer diameter thereof. A ground support is disposed in the region of ends of the drum. A collection channel provides communication for picked-up objects between the drum chamber and a collection receptacle for receiving the objects. The wall section of the housing and the drum cooperate with one another such that objects are accelerated along the wall section toward the collection channel and are ejected out of the drum chamber along a trajectory into the collection receptacle. A handle is operatively connected to the housing for moving the housing in the direction of operation.Type: GrantFiled: February 8, 2006Date of Patent: September 22, 2009Assignee: Andreas Stihl AG & Co.
