Arrangement for automatic working data set-up for driving implements
First Claim
1. An arrangement for automatic working data set-up particular to each type of tool bit for driving implements adapted to various types of exchangeable tool bits, said arrangement comprising;
- (A) data markings formed on said tool bits indicative of each type of tool bit, said data markings being arranged on a shank of each tool bit in the region serving for retention and actuating connection with the driving implement and distributed around a circumference of said tool bit;
(B) a marking read-out device built into a tool bit receptacle of the driving implement rigidly mounted to a housing of the implement, said read-out device being aligned with the data markings when the tool bit is inserted into the driving implement, said marking read-out device generating an electric signal corresponding to a sequence of the data markings on the circumference of the shank, when there, is relative motion between the tool bit and the housing; and
(C) an electronic evaluation arrangement for receiving the electric signal, said electronic evaluation arrangement generating appropriate adjustment orders for adjusting a drive unit of the driving implement for appropriate working parameters of the tool bit.

Abstract
Single or multi-track data markings are provided on the shank of a tool bit between a torque transmission region at one end and a working region proper for automatic working data set-up of a driving implement for exchangeable tool bits. The data markings consist of a sequence of notch-like depressions and lands, which are scanned by inductive proximity switch sensors. In case of multi-track codings, one track is used for clock timing. In case of single track codings, an rpm transmitter signal is used as a clock time signal during the information decoding in order to obtain an unequivocal identification signal. Signal evaluation occurs in a microprocessor with at least two counter register combinations, which alternately, in the sequence of the sensor signal, count the pulses of the time clock signal. The respective combination contents are compared in an evaluation unit of the microprocessor with prestored table values. In this way, appropriate driving parameters for each type of tool bit are made available for the motor drive.
