Abstract: A hacksaw with an improved mechanism for adjusting the tension on the blade. The mechanism includes a lever for vertically moving a rod to pivot a rocker arm to place tension on the rocker arm-held blade. The rod has a manually rotatable cross-member provided at its lower end. The rocker arm has a transversely extending seating groove provided on the lower surface of its rear portion to receive the cross-member and to retain it therein against rotational movement. The cross-member is rotatable by the user to provide a positive and replicable blade-tensioning means which is free from infinite adjustment-caused creep.

Abstract: An improved portable cassette recorder for use in an imprinter or the like, the recorder being adapted to process fan-folded transaction log sheets or the like. Each sheet incorporates a plurality of transaction data entry blocks disposed along the length thereof and a plurality of registration holes respectively associated with the data entry blocks. The recorder includes a sensing pin mechanism which senses the registration holes in the log sheets to ensure that each data entry block is in registry with the recorder imprinting station. In order to advance the log sheet from one entry block to the next, the sensing pin is first lowered beneath the log sheet and awaits the next registration hole. When it arrives, the pin is urged upwardly through the hole. At the same time, a brake engaging mechanism is actuated to brake the take-up spool and thus maintain the data entry blocks in registry with the imprinting station.

The recorder includes a sensing pin mechanism which senses registration holes in the log sheets to ensure that data entry blocks in the log sheet are in registry with the recorder imprinting station. In order to advance the log sheet from one entry block to the next, the sensing pin is first lowered beneath the log sheet and awaits the next registration hole, the pin being so shaped as to ensure positioning thereof beneath the log sheet. When the next registration hole arrives, the pin is urged upwardly through the hole. At the same time, a brake engaging mechanism is actuated to brake the take-up spool through a bell crank and push rod mechanism and thus maintain the data entry blocks in registry with the imprinting station.

Abstract: A variable amount imprinter and a portable transaction-log recorder usable therewith, the imprinter having a pivotally mounted head assembly, upon which is mounted a roller platen assembly for effecting imprinting. Two interlocks are provided to prevent closing of the head assembly until (a) a tray for a printing plate such as a credit card has been latched in place in the recorder and (b) at least one preselected item of the variable amount data has been set to a non-zero value. Releasable latching means lock the head in its closed position until the imprinting stroke of the roller platen assembly has been completed, at which time the head is automatically returned to its open position.Means responsive to movement of the roller platen assembly during the imprinting stroke reset the variable amount data to zero after it has been imprinted. Means are also provided for centralizing the digit wheels of the variable amount assembly prior to the imprinting thereof.

Abstract: An improved apparatus for the recording of credit card transactions at point of sale, and for reporting said transactions to a central accounting and processing activity. The instant invention includes a self contained, compact, portable and lightweight cassette-like transaction log recorder which is adapted to be releasably and operatively engageable with an imprinter mechanism. The recorder contains both an external duplicate sales ticket and an internal continuous form log sheet for the sequential recording of individual transactions at the time various data is applied to successive sales tickets. The recorder is also provided with external receiving means for receiving the customer's credit card at a receiving station, means for translating the card from the receiving station to an imprinting station, means for latching the card immovably at the imprinting station to an external removing station.
