Patent number: 8052402Abstract: A hand operated pump for generating negative and positive air pressure. The pump includes a pump body having a pump cylinder and a piston mounted for reciprocation in the cylinder. A selector valve communicates with the cylinder and is moveable between a positive-pressure position and a negative-pressure position. The arrangement is such that operation of an actuator to move the piston through a power stroke when the selector valve is in its negative-pressure position causes the pump to generate negative pressure at an outlet of the pump, and operation of the actuator to move the piston through a power stroke when the selector valve is in its positive-pressure position causes the pump to generate positive pressure at the outlet of the pump. A method of operating such a pump is also disclosed.Type: GrantFiled: October 20, 2008Date of Patent: November 8, 2011Assignee: Lincoln Industrial CorporationInventors: Scott A. Sanders, Ayzik Grach

Publication number: 20100294808Abstract: An improved follower packing unit for a grease gun is disclosed. The unit includes a hollow annular body of elastomeric material having a front wall, an annular side wall and a rear wall defining a cavity in the body. Rigid front and back structural supports rigidly support the front and rear walls of the elastomeric seal. The elastomeric seal and the front and back structural supports are fastened together to prevent separation and to form a unitary follower structure movable as a unit on a follower rod. The annular side wall of the elastomeric seal is resiliently deformable under pressure in a radial direction for sealing tightly against an interior surface of the barrel of the grease gun or against the interior surface of a tubular cartridge loaded in the barrel of the gun.Type: ApplicationFiled: May 22, 2009Publication date: November 25, 2010Applicant: LINCOLN INDUSTRIAL CORPORATIONInventors: Canlong He, Paul G.
