Abstract

1346537 Drilling machines METABOWERKE KG CLOSS RAUCH & SCHNIZLER 19 July 1972 [9 Aug 1971] 33703/72 Heading B3C [Also in Division B4] A tool for use as a drill, or a screwdriver, comprises a spindle 2 rotatable by an electric motor (not shown) in one sense or the reverse sense depending on the condition of an electric switch (not shown). With sleeve 8 cammed to the illustrated position by eccentric 10 on a rotatable shaft 11, a toothed ring 5 fast with the spindle will be prevented from being moved rearwardly into engagement with a second toothed ring 6 secured in the housing 1 upon the tool being pressed against a workpiece. The teeth on the rings have the form illustrated in Fig. 3, and the angle a is not greater than 65 degrees, and preferably 45 degrees. Thus with the tool conditioned as shown and used as a drill (i.e. with a drill bit attached to the spindle and with the spindle rotated in the one sense), it will perform pure rotary drilling. Rotating knob 14 through 180 degrees will allow the rings to engage when the spindle is forced rearwardly into the housing 1 against the force of spring 20; thus in this condition the tool with a drill bit will perform rotary percussive drilling and the flanks 31 of the teeth on the rotary ring 5 will be the leading flanks and will ride up flanks 31 of the teeth on the stationary ring 6. When used for screwing in and unscrewing, the spindle is rotated in the one sense and the reverse sense respectively, and the rings 5, 6 are prevented from engaging. Should the rings engage during unscrewing, jamming will not occur since the teeth will ride over each other due to the inclination of the flanks 32.
