The desired security is achieved by »that dea? Lid of the conventional cylindrical grinder is provided with a rigid projection (extension) which contains at its end a push button, can be set with the aid of which at right on geeetatem cover of the electric motor in operation "Per approach can glued to the lid a piece" blasted in »cast-on or otherwise fastened. If the cover is missing or not correctly attached, the motor cannot be switched on. How the new safety device works is described on the basis of the drawings.

The coffee grinder Ια usual cylindrical shape "consists of aas a lower part 1 and a bowl-shaped a lid 2 », the cylindrical outer wall of which is attached a rigid attachment 5 * which is preferably in the form of a lobe or a Has tongue and ends in a small cylindrical housing 4 open on the inside. Axial to the cylindrical surface " At the end, the housing wall 11 has a bore 12 “through dl © a push button 5 with collar 6 and with extension cup ea 7 inserted into the housing opening 14 is Washer 8 with hole 9 is used once?

When the cover 2 is properly attached to the lower part 1, the push button 5 with its central longitudinal axis is exactly coaxial with the circular opening 15 in the outer wall of the lower part 1, so that when the button 5 is pressed it penetrates the opening 15 and only one after the electrical pressure contact 16 shown with cracks closes in such a way that the motor is switched on and the fly blades are set in motion. As long as the push button 5 does not come to exactly in front of the opening 15 when the cover is properly closed, »it is not possible to switch on the coffee grinder ·
