Abstract: A connector for making connections to the post of an automotive lead-acid battery is disclosed. The connector includes a body portion having a pair of bifurcated ring portions each defining a circular opening therethrough, and a locking ring portion, also defining a circular opening therethrough with a pair of lugs affixed to the locking ring. The circular openings of each are designed to slip over and surround the battery post and when the locking ring is turned by means of the lugs, the lugs come into contact with the ring portions of the body causing the three rings to cut into the battery post around its total circumference by cam action and to lock in position by friction.

Abstract: Disclosed is a carburetor which regulates the supply of fuel and air in response to the vacuum pressure conditions in the mixing chamber between a downstream butterfly throttle valve and an upstream butterfly air valve. Liquid fuel is supplied to the mixing chamber through a nozzle with a number of small orifices and its delivery is controlled by a fuel supply valve operated by the air valve shaft. The air valve and fuel supply valve are operated in unison by a vacuum responsive actuator connected to the mixing chamber and adapted to adjust the air flow through the air valve in response to mixing chamber vacuum pressure. A second vacuum responsive actuator connected to the intake manifold is used to enrichen or lean the fuel mixture ratio in response to engine demand by bleeding air into the fuel supply line between the fuel valve and nozzle.
