Abstract: The protective casing includes a system of telescopic tubes (26 and 27) that cover a pair of telescopic tubular elements (13 and 14) connecting two universal joints (9 and 11) on a transmission shaft. The inner telescopic tube (26) is fitted with a grease nipple (35) that is connected via a tube (39) to a chamber formed by a bushing (41) and a sealing ring (63). A suitable lubricant can be injected into the chamber, from the exterior, via the grease nipple (35), so that the telescopic tubular elements (13 and 14) can be kept lubricated without this requiring the transmission being uncoupled.

Abstract: A compact hoist with a central hoist housing and an enclosed transmission located opposite a motor. The output shaft, of the motor, is guided coaxially through a transmission output shaft that is hollow and supports a sprocket wheel, or similar device, and receives power from the transmission. The hoist is particularly easy and economical to assemble, service and repair, and is flexible when in use. In a preferred embodiment, the motor shaft is mounted in a transmission cover opposite the motor and the transmission-output shaft is mounted, on one side in the wall of the hoist housing, and on the other side in an end plate of the motor. That configuration makes the invention particularly suitable for automatic assembly.

The locking pin (29) can easily be released from the exterior, and the protective casing remains stationary while the yoke is rotating.

Abstract: A fishing reel is formed of a spool, a drag mechanism, a transmission which transmits rotation of the spool to the drag mechanism, and a one-way transmission mechanism mounted on the transmission for transmitting drive to the drag mechanism only when the spool rotates in a fishing line unwinding direction. The fishing reel also has a transmission switching mechanism capable of establishing a condition in which power transmission between the spool and the drag mechanism is broken.

Abstract: A positioning spring for a triplan universal joint has a body with a first and second end. Arms to retain bearings extend from each end of the body. A resilient finger, between the arms on the body, secures the spring to a trunnion and positions the bearing with respect to the trunnion.

Abstract: A tripod constant velocity universal joint having an annular outer member, an inner member and three multiple component rollers. The interior surface of the outer member has three longitudinal lobes forming opposing pairs of parallel longitudinal guideways which are engaged by the multiple component rollers. The inner member is centrally positioned within the outer member and has three trunnions extending radially into the three longitudinal lobes. A multiple component roller is pivotally attached to each of the trunnions. Each multiple component roller has oppositely disposed pairs of elongated rollers, each of which engages an adjacent guideway that corresponds to its trunnion. The axis of rotation of the elongated rollers is substantially perpendicular to its adjacent guideway. Each elongated roller is mounted such that it can be axially displaced along its axis of rotation.

Abstract: A ball-type universal joint provides three concentric, relatively movable spherical elements that resists both compressive and extensive forces. An outer shell carries a first shaft and defines a medial chamber comprising more than half a hemisphere with a releasably fastenable outer portion to allow access. A medial shell carried in the outer shell chamber defines a spherical chamber comprising more than half a hemisphere with a releasably fastenable outer portion to allow access. An inner spherical ball carries a second shaft and is carried within the chamber defined in the medial shell. A plurality of ball bearings carried in indentations in the outer surface of the medial shell communicate with elongate slots defined in the interior surface of the outer shell to allow angulated motion of the outer and medial shells but prevent rotary motion.

Abstract: A fishing reel of the multiplier type has a frame and a shaft extending through the frame and carrying a rotatable line spool. A clutch member is mounted on the shaft to be shifted between a coupling position, in which it engages the line spool for rotating it, and a neutral position, in which it is disengaged from the spool. A mounting plate carried by the frame has a plurality of mounting pins parallel to the shaft. The mounting plate carries on these pins a clutch mechanism having a yoke in which the clutch member is rotatably mounted and which is displaceably mounted on two of the mounting pins for shifting the clutch member between its two positions. A spring presses the yoke in such a direction that the clutch member is urged towards its coupling position. A link arm is pivotally mounted at one end on one of the mounting pins and has at its other end a pivot pin on which a U-shaped member is pivotally mounted. The link arm is pivotable by a trigger.
