Patent number: 9388941Abstract: A compact lubricant injector is disclosed. The injector includes an injector body having an inlet for lubricant under pressure, an outlet, and a measuring chamber for receiving lubricant from the inlet. A piston is movable in the injector body along a first axis through a stroke in the measuring chamber for the discharge of a measured volume of lubricant from the measuring chamber and thence through the outlet. A valve is movable in the injector body along a second axis different from the first axis. The valve is responsive to pressure conditions in the inlet for operation of the injector in a cycles ending in a state for venting the injector to effect recharging of the measuring chamber involving the transmission of lubricant from the inlet to the measuring chamber. A combination of at least one such lubricant injector and a manifold is also disclosed.Type: GrantFiled: October 17, 2011Date of Patent: July 12, 2016Assignee: Lincoln Industrial CorporationInventors: Thomas M.

Publication number: 20080240944Abstract: An air-operated pump for pumping material such as oil or grease. The pump is powered by an air motor which operates to reciprocate a piston and plunger to effect a pumping action. The air motor is modular in that the air valve system is contained in a single housing fastened to the pump head. The housing is removable as a unit from the pump head to facilitate servicing of the air valve system.Type: ApplicationFiled: March 28, 2007Publication date: October 2, 2008Applicant: LINCOLN INDUSTRIAL CORPORATIONInventor: Thomas M.

Patent number: 6631787Abstract: A lubrication system for a vibratory apparatus such as a hydraulic striking device. The system includes a lubricant pump for pumping lubricant to one or more points of lubrication on the device and a drive for the pump powered in response to vibration of the device. The system includes a base for attachment to the device for vibration therewith, and a lubricant pump for pumping lubricant from a supply. The pump includes a cylinder and a plunger reciprocable in the cylinder through a stroke between a retracted position for intake of lubricant into the cylinder and a forward position for delivery of the intake from the cylinder. A weight is mounted on the base for oscillation in response to the vibration of the device, oscillation of the weight effecting reciprocation of the plunger through a stroke.Type: GrantFiled: December 5, 2000Date of Patent: October 14, 2003Assignee: Lincoln Industrial CorporationInventors: Paul G. Conley, Thomas M. Arens, Zdravko Paluncic, Andreas Schoenfeld
