The main 2 machines that Herman Hollerith invented for the 1890 US census were a manually fed electromechanical card tabulator (for counting items punched on the cards) and a manually fed electromechanical card sorter connected to the tabulator by a cable (for separating cars into categories for later processing on other tabulator/sorter machines to extract more specific information).
To support these machines he also invented a manually operated pantograph card punch, to allow a person to transfer the data from the paper census form to a punchcard.
