Abstract
A spray head adapted for directing an aerosol lubricant onto the wear points of a drive chain, such as a motorcycle chain. The spray head is designed to receive a supply tube connectable to the outlet port of an aerosol can. The spray head includes a recessed portion having a pair of concave cavities each having a fluid outlet for dispensing lubricant directly onto the lateral link plates of the chain, and a central protrusion having a planar guide surface adapted for travelling over the upper surfaces of the chain rollers.
Claims9
A spray head for directing lubricant onto a drive chain having a plurality of rollers and a plurality of lateral plates for linking said rollers together, said spray head comprising:
- (a) a solid body having a recess formed in a bottom portion thereof for receiving said chain, wherein said recess is defined by opposed end walls and a bottom wall extending between said end walls, said bottom wall comprising a guide surface projecting downwardly from a central portion of said body for slidingly engaging said rollers and first and second upwardly concave surfaces extending between said guide surface and an adjacent end wall, said first and second concave surfaces defining respective first and second cavities on opposite sides of said guide surface;
- (b) an inlet formed in said body for removably receiving one end of a conduit connectable to the outlet port of an aerosol can;
- (c) a first outlet formed on said first concave surface for dispensing lubricant into said first cavity;
- (d) a second outlet formed on said second concave surface for dispensing lubricant into said second cavity;
- and
- (e) fluid delivery means within said body for delivering lubricant from said inlet to said first and second outlets such that the decrease in fluid pressure between said inlet and said first and second outlets is substantially equal.
A spray head for directing lubricant onto a drive chain having a plurality of rollers and a plurality of lateral plates for linking said rollers together, said spray head comprising:
- (a) a solid body having a recess formed in a bottom portion thereof for receiving said chain, wherein said recess is defined by opposed end walls and a bottom wall extending between said end walls, said bottom wall comprising a central portion projecting downwardly for slidingly engaging said rollers and first and second lateral portions defining first and second cavities on opposite sides of said central portion between said central portion and an adjacent end wall;
- (b) an inlet formed in said body for removably receiving one end of a conduit connectable to the outlet port of an aerosol can;
- (c) a first outlet formed on said first lateral portion for dispensing lubricant into said first cavity;
- (d) a second outlet formed on said second lateral portion for dispensing lubricant into said second cavity;
- and
- (e) fluid conduit means within said body for delivering lubricant from said inlet to said first and second outlets, wherein said conduit means is configured such that the decrease in fluid pressure between said inlet and said first and second outlets is substantially equal,
- wherein said first and second outlets are spaced above said lateral link plates when said central portion contacts an upper portion of said chain rollers.
