  • Patent number: 10307036
    Abstract: A warewash machine arm mechanism includes a liquid supply shaft assembly including a rotatable sleeve bearing mounted thereon, and an arm assembly including an elongated interior liquid flow space along an arm body and one or more liquid ejection orifices. The arm assembly is releasably mounted to the supply shaft assembly via a latch mechanism of the arm assembly that engages the rotatable sleeve bearing such that the arm assembly rotates with the rotatable sleeve bearing during ejection of liquid from the liquid ejection orifices.

  • Patent number: 6669544
    Abstract: A protective hood (1) for a right-angle grinder having a tightening device, which has a tightening band (4) firmly connected to the protective hood (1) for a right-angle grinder, the two ends (5, 6) of the tightening band being embodied as a first and second eyelet (7, 8), so that they form a first and second abutment (9, 10) and can be connected to one another under tension by means of at least two tightening elements, the first tightening element being a tightening lever (2), which with its first end (15) can be supported in the first eyelet (7) pivotably about a first axis (9a) and which can be brought into a first position in which the tightening device is not tightened, and into a second position in which the tightening device is tightened, becomes capable of being produced at less expense with still high quality by providing that the second tightening element is a spring (3), which can be connected movably to the tightening lever (2), the spring (3) being pivotably supported about a second axis (11) in

  • Patent number: 6669542
    Abstract: An angle grinder with a housing 2 can be produced more economically by providing that it has a mounting shell 3, a cap shell 4, and an insert part 1 between these two shells. The insert part 1 is equipped with a first fixation device 10 and a second fixation device 11 for fixation between the mounting shell 3 and the cap shell 4, and it has a spindle locking receptacle 12 and spindle bearing receptacle 13. The mounting shell 3 has a first fixation means 30, which is engaged by the first fixation device 10 of the insert part 1. The cap shell 4 has a second fixation means 40, which engages the fixation device 10 of the insert part 1. The insert part 1 also has a second fixation device 11, which can be brought into engagement with suitable means on the mounting shell 3 and the cap shell 4.
