The invention relates to a novel method and apparatus for resurfacing lacrosse balls effecting extended life of the balls, uniform size, and elimination of surface waste.
The invention most closely corresponds with USPTO Class 15/28 wherein Class 15 relates to brushing, scrubbing and general cleaning, and sub-class 28 includes a method for grinding a roll, roller, shaft including a spliced shaft, ball, sphere, or piston.
The invention comprises a novel method and apparatus whereby lacrosse balls can be resurfaced using a method of abrading which removes a very small amount of surface material, retains the spherical shape, evacuates abraded waste, and the ball remains in compliance with national lacrosse regulations.
The inventive apparatus contains an electric motor within a hollow receptacle outfitted with an inverted abrasive disc. When the inventive method is applied, the disc speed is faster at the outer edge than towards the center. Thus, the ball will spin from the center of the disc to the outer edge, while very slowly rotating the same way as the disc. The ball movement in diametric direction and at differing speed provides even abrasion and allows the ball to retain its original shape.
The inventive method utilizes a random orbit motion which keeps the side spin on the balls slower. Being barred from gaining too much momentum due to the random action of the motor drive unit, the balls will not tend to bounce or hop. Rather a constant grind action results, and thus a more even removal of surface material is achieved. This is important to retain the ball's shape and regulation size parameters.
The abrasive disc is inverted to take advantage of gravity and centrifugal force of the balls being abraded. Pursuant to the spinning action, the ball will be driven outward, rotating slowly with the disc yet oppositely spinning as the surface is gently abraded. In this way, a minute amount of surface material is removed, and the ball's spherical proportions are retained.
The typical Lacrosse ball utilizing this apparatus and method may be resurfaced approximately thirty (30) times each and still remain in comportment with regulations regarding lacrosse balls in competition.
The sole prior art lacrosse ball resurfacer uses a large “bucket” and claims to resurface multiple balls in a single cycle. This, however, is not ideal as the balls bounce erratically as they are ejected off the abrading surface, and will not be as resultantly uniform as in the inventive method. Additionally, the inventive sanding disc is removable with a Velcro-like attachment and does not have to be heated or pried off as with the prior art ball resurfacers.
In the inventive method, abraded material is evacuated into removable and reusable dust receptacles. Prior art does not provide this important feature as the abraded material contains a variety of plastics and chemicals and is harmful when breathed. Regardless of where the inventive method and apparatus is applied, indoors or out, it is safe for the user as no contaminants will be airborne.
The inventive apparatus is offered in sizes ranging from 4 inches in diameter to 12 inches in diameter for user choice on how many balls to process at a time, and can resurface multiple balls per cycle while retaining the regulation size and shape. Volume of ball load is the main difference in the sizes.
The invention is described in further detail by reference to three drawings sufficient in detail to describe the invention in which:

The resurfacer is powered by a 220 volt motor encased in the base of the resurfacer's cylinder 90 and operates applying random orbit motion. A power cord 100 is required, but alternate forms of power would be obvious embodiments. The inventive method utilizes a random orbit motion to keeps the side spin on the balls slower. Being barred from gaining too much momentum due to the random action of the motor drive unit, the balls will not tend to bounce or hop. When a ball being abraded bounces within the chamber, an uneven amount of material is abraded and the ball will lose its shape. This is important as the game is regulated in most areas of the world, and the balls are inspected.

Thus, the ball will spin from the center of the disc to the outer edge, while very slowly rotating the same way as the disc.

The inventive ball resurfacer is a vast improvement over any forms of prior art in the industry and solves a long felt need of not only properly resizing the balls during resurfacing operations, but to eliminate the abraded material in a safe manner.
