Abstract: A module for selectively deploying a reciprocable tool, such as a hole punch, which is reciprocated by a press. The module includes a housing which is attached to the ram of the press. The housing retains a reciprocable tool within a bore for movement between an extended position and a retracted position. The reciprocable tool is connected to the housing by means of a telescopic linkage comprising a cone clutch having resilient fingers that selectively grip a pin. The housing includes a conical surface which engages beveled portions of the resilient fingers holding them in a closed position. A spring biases the cone clutch to its closed or gripping position unless air pressure is supplied to an air chamber which counteracts the biasing force of the spring to open the resilient fingers. When the resilient fingers are open, a shifting means comprising a spring, or alternatively a solenoid, is effective to shift the pin between an extended position and a retracted position within the cone clutch.

Abstract: A punching device for punching coded key cards and the like comprising a plurality of punches, each of which is selectively movable in respective guide. Balls of ferromagnetic material are positionable in a first punching position and a second passive position. Solenoids with movable cores are arranged to selectively move the balls between the first and second positions.

Abstract: An apparatus for punching of symbols into template material with a punching tool. The punching tool has punching pins selectable by corresponding selector means. An operating mechanism, after selection of the punching pins by the corresponding selector means presses the punching pins through the template material in a grid arrangement characteristic of each symbol to be punched into the template material. The punching tool has several parallel rows of punching pins, of different punch sizes for punching of symbols in different sizes of lettering and/or types of lettering. The selector means selects and operates the punching pins of only one punching row, in any desired combination for punching of symbols according to a straight-line dot grid.

Abstract: A combination paper tape punch and reader having a bi-directional stepping tape transport controlled by a continuously oscillating magnetically activated pawl. A further improvement is a punch interposer geometry allowing for easy removal of the punch and die. A single motor and timing signal is used for both punch and reader tape transports.

Abstract: In a tape punching device, punching needle selection takes place by means of selector strips slidably mounted in a rocking arm and engaged by armatures of selector magnets at their rear ends in the vicinity of the rocking axis of the rocking arm. The rocking arm and selector magnets are mounted in a separate case which is insertable in a main housing containing a continuously rotatable main shaft with an eccentric engageable by an open fork at the front end of the rocking arm. The main housing also contains a feeding mechanism alternatively usable for forward feed and back-space through 180.degree. displacement of a pulse supplied to a feeding magnet.

Abstract: Actuator for use with a push-button keyboard in which the keys are arranged in an array of intersecting rows and columns. A single solenoid is provided for each row and column, and means operated by the solenoids causes the key to be depressed at the intersection of a row or column for which the solenoids are energized.

Abstract: The deflection of a subterranean tunnel is measured with a rod-like, self-contained instrument that is adapted to be inserted into a radially extending bore of the tunnel adjacent an end of the tunnel where the tunnel is being dug. One end of the instrument is anchored at the end of the bore remote from the tunnel wall, while the other end of the intrument is anchored adjacent the end of the wall in proximity to the tunnel wall. The two ends of the instrument are linearly displaceable relative to each other; the displacement is measured by a transducer means mounted on the instrument. Included in the instrument is a data storage means including a paper tape recorder periodically responsive to a parallel binary signal indicative of the measured displacement.

Abstract: A punch device for coding cards, tapes and the like comprises a pivotably mounted spring biased punch lever, and a punch member for punching a code into a program card or the like movably mounted on one end of the punch lever. An oscillatable yoke is connected to the punch lever through a hammer lever. A rotating eccentric drive rotatably mounted in the yoke continuously oscillates the yoke. An electromagnetically actuable pawl is reciprocably movable against a spring biased trigger lever for pivoting the trigger lever into a position between an end of the hammer lever and the end of the punch lever in which the punch member is movably mounted. When the trigger lever is moved by the pawl between the hammer lever and punch lever, the oscillation of the yoke by the eccentric drive upwardly moves the punch member into a punch position.

Abstract: A mechanism for achieving a precisely-timed intermittent operation includes an oscillating drive having continuously repeating oscillating cycles during which an output member of the oscillating drive oscillates back and forth between opposed dead center positions. A driven structure which has an input portion is provided for producing a predetermined intermittent operation. A motion-transmitting member has an operating position situated in the path of movement of the output member of the oscillating drive to be moved thereby, the input portion of the driven structure being situated in the path along which the motion-transmitting member is moved by the output member so that when the latter is in its operating positon a drive is transmitted from the output member through the motion-transmitting member to the driven structure to operate the latter. This motion-transmitting member has a retracted, rest position beyond the path of movement of the output member.

Abstract: A tape punch machine in which, to assure accurate and reliable tape movement, a stepping motor for feeding the tape receives two pulses for each spacing increment of the tape. The punches are selected by interposers which are not released if the same punch function is to be repeated in successive cycles of the machine.

Abstract: A selectively operable interposer mechanism for positioning bars, or the like, in a card selector or coder. Each interposer includes an interposer blade of magnetically responsive material disposed in a longitudinal slot of a nonmagnetic platen. A bar is disposed in each slot and is adapted to be pushed by the interposer blade acting through a rolling disc disposed in the slot between the blade and bar. Disposed directly above each interposer blade is a solenoid coil effective, when engaged, to pivot the associated interposer blade into contact with a permanent magnet which captures the interposer blade. A pusher assembly including the permanent magnet is operative to displace each captured interposer blade and the associated bar longitudinally along their respective slots from a rest position to a displaced position. After a coding or sorting operation, the pusher assembly returns the bars and interposers to their initial rest position.

Abstract: A tape punch machine in which several subassemblies are arranged for accurate adjustment and easy detachment; to assure accurate and reliable tape movement a stepping motor for feeding the tape receives two pulses for each spacing increment of the tape. The punches are selected by interposers which are not released if the same punch function is to be repeated in successive cycles of the machine.
