Abstract
A handled ratchet-breaker bar tool characterized by the provision of one or two elongated pivotal handles which permit tool usage at usually remote locations. A removable knob is included for added pressure application at the job site, where the length of the assembly for such knob is adjustable. Additionally, a ratchet directional control is effectively arranged for ready operator usage. Moreover, the instant tool is easily converted to satisfy a variety of nut/bolt tightening and/or loosening requirements.
Claims2
In a tool including a base positioning an operating drive at the mid-area thereof, a pair of elongated handles pivotally mounted to and extending from said base at each end and laterally with respect to the longitudinal axis thereof, where each elongated handle is individually positionable in any one of a range of pivotal positions by structure including a spring-urged control member selectively engaging a pin with one of a plurality of cooperating notches, where said operating drive mounts extendible and rotatable knob means which serves to receive manual pressure for application against a workpiece during a use condition, and where said knob means is removable and spring-urged into a mounted position on said operating drive, said knob means including a sleeve, an elongated body received in said sleeve having a plurality of cut-outs therein, and a spring-urged pull-pin in said sleeve for selectively engaging one of said plurality of cut-outs, said elongated body including a spring-urged shaft operating a detent device in said operating drive.
In a tool including a base positioning a ratchet mechanism at the mid-area thereof, a pair of elongated handles pivotally mounted to and extending from said base at each end and laterally with respect to the longitudinal axis thereof, where each elongated handle is individually positionable in any one of a range of pivotal positions by structure including a spring-urged control member selectively engaging a pin with one of a plurality of cooperating notches, where said ratchet mechanism includes a rotatable gear presenting a square operating drive, hand operated means for selectively controlling the movement mode of said rotatable gear to be fixed, clockwise or counterclockwise in said base, and where said movement control means includes selectively and independently rotatable dowels, a toothed lever pivotally engaging said rotatable gear, and a resilient plate continually urging said toothed lever toward the location thereof which establishes the fixed mode of said rotatable gear, said dowels selectively engaging said toothed lever to limit its pivotal motion in either or both pivotal directions.
