Total Claims: 10
Claim 1
Independent Claim
334 words
An automatic call repertory device comprising a first rotatable shaft, an electric motor drivingly connected with said shaft, a plurality of second shafts rotatively solid with each other, each having mounted thereon a plurality of spaced groups of frictionly urged discs, each group including a number of alternate memory discs and separation discs, each memory disc having two diametrically opposed notches in the periphery thereof and each separation disc having a single notch in the periphery thereof, the notches in consecutive ones of said separation discs being 180* shifted with respect to each other, a third rotatable shaft drivingly connected with said first shaft, a plurality of fourth shafts rotatively solid with each other, each having a number of pawl control members thereon, a fifth rotatable shaft drivingly connected with said third shaft, dial means drivingly connected to said fifth shaft and having a stop means associated thereto, a plurality of manually depressible keys each being associated to one of said groups of discs and operatively connectable to a respective pawl control member, electric switch means inserted in the energizing circuitry of said electric motor, first cam means mounted on said third shaft, said cam means having associated thereto switching means operatively connectable to pawl control member, second cam means mounted on one of said plurality of second shafts and having associated thereto switching means operatively connectable to pawl control member and which is angularly shifted in the rotation direction of said second shaft with respect to said switching means associated to first cam means, the said angular shift being less than half the angular deviation of said dial means between the digit one position and said stop means thereof, thereby to disable said electric switch means such that the electric motor is disenergized and the device stopped to rotate when that one of said pawl control members which is associated to the selected key does not engage a notch in any of said memory discs during one half revolution of said second shafts.
