Abstract
A light-duty, multi-purpose lubricant particularly formulated for use on the diverse bearing surfaces of a bicycle chain and other similar low-speed and low-temperature mechanisms operating in a dusty environment. The lubricant comprises an insoluble soap, preferably Calcium Stearate in suspension in a volatile solvent-based solution of paraffin wax and Petrolatum. After application and evaporation of the solvent the composite dry lubricant exhibits good penetration and load bearing properties without the dirt-retaining character of greases. The undissolved particles of soap combine with dirt particles to break-down portions of the lubricant into a dry flaky dust which is sloughed off the mechanism.
Claims9
A multi-functional, light duty lubricant comprising 5 to 15.5 percent per total weight of an insoluble soap in suspension in a solution of 10 to 30 percent per total weight of a soluble wax having a melting point between 45.degree. C. and 55.degree. C., 2 to 9 percent per total weight of a hydrocarbon lubricant, and 40 to 80 percent per total weight of a volatile solvent, wherein said solvent is selected from a group consisting of straight-chain hydrocarbons having 5 to 8 carbon atoms and boiling points between 35.degree. C. and 110.degree. C., and aromatic hydrocarbons,
- wherein a bond formed between said wax and said hydrocarbon lubricant is weakened by said soap to a point whereby said bond is breakable by contact of said soap with foreign dust particles.
A method for lubricating a bicycle chain which comprises contacting all areas of the chain with a mixture of 5 to 10 percent per total weight of a insoluble soap comprising a Stearate of a heavy metal selected from a group consisting of Aluminum, Barium, Calcium, Lithium, Magnesium and Zinc, in suspension in a solution comprising:
- 10 to 30 percent per total mixture weight of a wax having a melting point between 45.degree. C. and 55.degree. C.;
- 2 to 9 percent per total mixture weight of a hydrocarbon lubricant;
- and
- 40 to 80 percent per total mixture weight of a volatile solvent;
- wiping all excess mixture off said chain;
- and allowing said mixture to dry.
A multi-functional, light duty lubricant comprising 5 to 15.5 percent per total weight of Aluminum Stearate in suspension in a solution of 10 to 30 percent per total weight of paraffin wax, 2 to 9 percent per total weight of lubricating oil and 40-80 percent per total weight of Perchloroethylene.
