    Abstract: A hose connector having a tubular body has improved barb means thereon for retaining a hose on the body of the connector. The barb means comprises a plurality of small barbs arranged in dual tapering sets. The first set of barbs increases in size from an end of the tubular body to an intermediate portion thereof at one mean slope, and the second set of barbs increases in size, moving from the intermediate portion toward the opposite end of the body, at a larger mean slope. The barbs provide a very tight interference fit with the hose, but yet permit the hose to be manually installed on the body of the connector.

    Abstract: A torque transmitting and controlling device is disclosed, wherein at least one fluid motor having a low stall torque is connected to one end of a shaft and is adapted to apply a predetermined low torque to one of a pair of threaded members connected to the other end of the shaft. At least one other fluid motor is connected to the shaft through an overrunning clutch so that the first motor is prevented from driving the second fluid motor during the low torque applying operation. When fluid under pressure is supplied thereto, the second fluid motor rotates the shaft an additional number of degrees to develop a desired tension in one or the other of the threaded members. A cam carried by one of the rotatable parts of the device actuates a valve in the fluid circuit of the device to shut off the flow of fluid to the second fluid motor after the shaft has rotated the additional number of degrees. At the completion of the torquing and tensioning operation, the device automatically applies a mark to structure adjacent the threaded members to indicate that the members have been tensioned. During or after disengagement of the device from the threaded members, an automatically or manually actuated valve in the fluid circuit of the device causes the first fluid motor or a separate fluid motor to rotate the shaft in a direction opposite from the direction of rotation thereof during the torquing operation until a pair of stops respectively carried by one of the parts of the overrunning clutch and the supporting frame of the device engage each other. The spacing between the two stops is adjustable to permit adjustment of the final tension obtained in one or the other of the threaded members.
