Patent ES-8104035-A1 (ES)
Title: Motor driven hand tool, especially combination tool for home-workers.
IPC: B25F3/00
Filed: 1980-08-08
Abstract: A reversing switch, controlling the direction of rotation of the working spindle of a combination motor-driven hand tool, displaces a rack rod in a direction parallel to the axis of the spindle to provide an interlock both with a percussion boring feature and with provisions for seating attachments on the chuck sleeve of the tool, such as a circular saw. When the percussion boring feature is put into operative position, the rack rod is caused to prevent moving the reversing switch from right-hand rotation to left-hand rotation. When the switch is set for left-hand rotation, the seating surface of the chuck sleeve locks to prevent mounting an attachment and, at the same time, the percussion boring mechanism is blocked in an out-of-service position.
