Abstract: A device comprises a sheet bearing informational material relating to a rotary brush and includes a threaded rod fastened to one edge of the advertising material. The opposite end of the rod is secured into a threaded opening provided in the tool for connection with a threaded shaft of a driving apparatus in such a manner that the sheet of advertising material is erect when the brush is positioned on its working face.

Abstract: A guidance device for drilling panels having a supporting element capable of being fixed on two panels and of receiving a guidance element provided with drill bushes in two different positions for the drilling of an edge of a first panel and for the drilling of a face of a second panel near one of its edges in its face adjacent to the first panel in order to form an L-shaped assembly secured together by dowels received in the drilled holes. The device also positions drill holes in the panels for forming a T-shaped assembly.

Abstract: The invention relates to a case for displaying and storing electric tools such as a mini-drill and the case also contains a shelf (38) for displaying and supporting accessories (14) usable with the mini-drill (12), together with a compartment on the back of the case for receiving a source of electric energy such as rechargeable or non-rechargeable batteries suitable for feeding electric power to the mini-drill.

Abstract: A jig for locating holes to be drilled in two panels (P1, P2), in particular wood panels, for assembling the panels at right angles to each other by means of dowels (82) lodged in the holes. The jig comprises a housing (10) having two perpendicular branches (14, 16) each of which slidably receives a corresponding plate having a drilling bush (32, 34) passing therethrough, and means (68) for moving the two plates in synchronism with one another as a function of the thickness of the panels.

Abstract: A sanding head providing for the extraction of dust produced during sanding, and comprising a shaft casing, a shaft rotatably mounted in the casing and capable of being driven by motor means, a circular backing plate of a ventilated type, which is connected to one end of the shaft, said circular backing plate being provided in its front face with ventilating grooves and having in its center a hollow cylindrical element, which has a closed front end and which is provided, adjacent its closed front end, with lateral windows communicating the inside of the hollow cylindrical element with the ventilating grooves, and a means for detachably fixing an abrasive disk to the closed front end of the hollow cylindrical element. The hollow cylindrical element of the plate is rotatably mounted in the shaft casing at one end thereof, whereas the shaft is rotatably mounted only at the other end of the casing.

Abstract: A sanding apparatus comprising a grooved circular backing plate adapted to be detachably secured to one end of a rotatably driven hollow shaft and supporting an abrasive-coated paper disc formed with a plurality of through holes communicating with grooves formed in the front face of the backing plate, a hollow cylindrical member forming an extension of the hollow shaft and protruding in a recessed central portion of the front face of the backing plate through a central hole thereof, a free space being provided between the central portions of the backing plate and abrasive-coated paper disc, respectively, around the hollow cylindrical member in which radial orifices are formed for allowing said free space to communicate with the interior of said member and of the hollow shaft coupled to suction means.
