Lincoln patented the first lever grease gun to work with a full stroke operation called the Model 1242. This meant that a hand-held grease gun could generate up to 10,000 lbf/in² (70 MPa) of pressure. Operators of the unit could push grease into blocked or "frozen" fittings and the unit allowed for work in confined areas.
Grease fitting on a bearing A grease nipple on the driver's door of a 1956 VW Beetle. A grease fitting, grease nipple, Zerk fitting, grease zerk, Alemite fitting, or divit is a metal fitting used in mechanical systems to feed lubricants, usually lubricating grease, into a bearing under moderate to high pressure using a grease gun.
For parts that are inaccessible for lubrication after assembly, a dry film lubricant can be sprayed. After the solvent evaporates, the coating cures at room temperature to form a solid lubricant. Pastes are grease-like lubricants containing a high percentage of solid lubricants used for assembly and lubrication of highly loaded, slow-moving parts.
The 100 mm (4-inch) and 125 mm (5-inch) Storz couplers have been specified in NFPA 1963, Standard for Fire Hose Connections, since the 1993 edition. U.S. cities that have fire hydrants with 125 mm Storz connectors include Raleigh, NC [ 5 ] and the City of Corvallis, OR (adapter on 4-inch threaded outlet).
A grease gun (pneumatic) A grease gun is a common workshop and garage tool used for lubrication. The purpose of the grease gun is to apply lubricant through an aperture to a specific point, usually from a grease cartridge to a grease fitting or 'nipple'. The channels behind the grease nipple lead to where the lubrication is needed.
The diagram from Beard's 1897 coupler patent [1]. Janney couplers were first patented in 1873 by Eli H. Janney (U.S. patent 138,405). [2] [3] Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; [1] Beard's patents were U.S. patent 594,059 granted 23 November 1897, which then sold for approximately $50,000, and U.S. patent 624,901 ...
