Abstract: Rather than engage the grooves of a cartridge's splined hub by means of fingers attached to a reel motor shaft, the present invention uses a mechanical coupler mounted on the motor shaft which contacts the spline lands at two places and locks the mechanical coupler position by insertion of a spring loaded tongue into one of the grooves of the spline. This groove is angularly located midway between the lands which contact the mechanical coupler, effecting a "three point" engagement of the mechanical coupler with the hub. The land contacting surfaces and the tongue are chamfered to facilitate engaging the hub for slight off-axial misalignment of the hub and mechanical coupler. The spring loaded tongue forces the spline contacting surfaces of the mechanical coupler into a "zero clearance" fit with the contacted lands of the spline, providing an intimate and backlash free connection between the hub and driving motor.

Abstract: A quick safety release for bull ropes and bare back riggings. One ring on the bull rope is held to the release device by a first ring latch which is pivoted to a release frame. A pivoted spring-loaded latch arm which in its normal position is perpendicular to the ring latch holds the ring latch in position preventing it from rotating about its pivot. A release line or cord is connected to the latch arm. When the bull rider pulls the release line the latch arm is pulled away from the ring latch permitting it to come unlatched from the ring of the bull rope.
