Abstract: Apparatus for transferring power from the battery of a service vehicle to the battery of a second vehicle, wherein the final connection between the batteries is made from a remote location via a radio transmitter and a receiver which is mounted in the casing of the apparatus to actuate a solenoid in response to a signal from the transmitter. The circuit between the solenoid and the receiver includes a transistor to control current through the solenoid coil and the base of the transistor is connected to the battery of the second vehicle. Cables used to attach the apparatus to the second vehicle battery are wound on a spool having an interrupted ratchet on one end thereof, the ratchet engaging a ratchet lock that pivots in one direction to hold the reel when the reel is turned in one direction to pay out the battery cables and the ratchet lock pivoting in the other direction within a ratchet wheel interruption to permit free rotation of the reel in the opposite direction for retrieval of the cables on the reel.

Abstract: An improved drain valve is disclosed for selectively sealing a conduit. The drain valve comprises a drain housing installed in a bathtub or the like, latching means threadedly coupled to the housing and a combination drain stopper and actuator coupled to the latching means. A locking member coupled to the latching means is adapted to allow the latching means to threadedly engage the drain housing, but prevent disengagement therefrom, without the use of a tool specially made to release the locking member. Upon release of the locking member by use of the tool, the latching means and combination drain stopper and actuator may be disengaged from the housing.

Abstract: Apparatus for transferring power from the battery of a service vehicle to the battery of a second vehicle, wherein the negative battery terminal of the service vehicle is connected to the frame of the service vehicle, which utilizes a spring-loaded reel for storing the jumper cables in the service vehicle and where one of the cables is permanently connected to the frame of the service vehicle and the other cable is permanently connected to the positive terminal of the battery in the service vehicle. The reel is preferably positioned in the rear of the service vehicle, whereby the vehicles may be aligned with the traffic when the apparatus is being utilized to start a stalled vehicle.
