Abstract
Abstract An electromechanical telephone dialer for connection to a conventional telephone system including a dial switchboard matrix having a plurality of columns each with 10 openings, one each of the telephone number digits. A contact strip is secured adjacent each column. An input board has a contact button for each opening, with depressions extending the contact button passed the associated strip. A carriage moves a leaf spring contact over each column to complete the circuit from the depressed button to the strip. A similar interlock board is mounted in stacked relation and has a common switch for each column actuated by the aligned buttons. The circuit boards and a stripping switch are interconnected to sequentially scan each of the columns, with the first column scanned until the appropriate character related contact means is engaged. The carriage is spring reset and coupled to actuate the dialing means. The cycle continues until the last number in the final column is transmitted. A drum timer is connected to initiate a code transmitting cycle, transmit a message, if desired, over the telephone lines and then reset the apparatus.

An automatic call transmitting apparatus for transmission over a telephone line system employing a plurality of unique signals established in sequence for dialing between a transmitting station and a select one of a plurality of receiving stations, each receiving station having a unique multiple call code including a plurality of code character positions with each element selectively including said unique signals, comprising a circuit altering matrix including a plurality of groups of individual circuit altering means, one for each call code character position for coded actuation in accordance with the several elements in said telephone call system to permit insertion of the selected one, scanning means for sequentially scanning each of said plurality of switch means for each of said call code elements in proper sequence, and dialing signal means actuated in accordance with said scanning means to establish the signals on the telephone line connection means in accordance with the code characters, a second circuit altering matrix including a plurality of groups of individual circuit altering means, one for each call code character position in said telephone call system, stepping means forming a part of said scanning means and connecting said scanning means into circuit through said second matrix for sequentially scanning each of saiid first and second matrix, said first and second matrix being secured to a pair of stacked boards, each matrix includes a switch column with said first matrix having a plurality of individual switch means one for each call code character, said columns being located in adjacent parallel arrangement, said second matrix including a common switch means for each column, each of said columns including switch control openings aligned with each individual switch means, selection means adapted to be passed through said openings to enable an aligned individual switch means and the common switch means, said scanning means including a switch actuator mounted to move over said columns and having contact means responsive to engagement with a selection means to activate the corresponding switch means.
Claim 3
Dependent Claim
54 words
The automatic call transmitting apparatus of claim 1 wherein said scanning means includes a stepping switch means for successively connecting the corresponding columns of said first and second matrix into circuit, and drive means for said stepping switch means including a start means and a step means connected in circuit through said second matrix.
Claim 4
Dependent Claim
87 words
The automatic call transmitting apparatus of claim 1 having a motor, a linear drive means coupled to said motor and said actuator, said dialing signal means including a driven switch means actuated to transmit a call signal to a remote station, a constant rate return means coupled to said actuator and driven switch means to return them to an initial position, and stop means responsive to activation of an individual switch means by the scanning means to release the dialing means and thereby dial the corresponding code.
Claim 5
Dependent Claim
53 words
