Abstract

222,440. Krupp Akt.-Ges., F. Sept. 26, 1923, [Convention date]. Drilling machines. - In a portable powerdriven drilling or like machine having a casing containing a rotary power element and a handle attached to the casing, the handle is yieldingly secured to the casing so that, on the tool encountering excessive resistance, relative motion between the two will ensue and the drive will be stopped. As applied to an electric drilling-machine the casing A, having a back centre a<1>, carries a rigid handle a<2> and a pivoted handle B, the latter being provided with a contact-piece b<3> which is engaged with a contact a<4> on the casing by a spring C. If the tool meets undue resistance the casing rotates relaytively to the handle B and breaks the circuit to the motor D, whereupon a spring pawl E secures the handle in the cut-out position. Specifications 13011/05 and 26750/05 are referred to.
