Abstract
A syringe for applying adhesive resin to the junctions of tennis racket netting, comprising a cylinder and a piston and two or four coextensive tubular spray nozzles projecting from the end of the cylinder opposed to the piston. By applying the spray nozzles to the corners of a junction between two strings of netting, equal amounts of adhesive can be discharged from said spray nozzles and these drops of adhesive will combine to form a solid connection of the two strings at their point of junction.
Claims14
A syringe for applying adhesive resin to the junctions of racket netting, comprising a reservoir cylinder to contain such adhesive resin and an injecting piston to expel adhesive resin from such reservoir cylinder and at least two separate adjacent parallel tubular spray nozzles fluidically coupled with and extending from the end of the reservoir cylinder to provide simultaneous, substantially identical doses of adhesive resin therethrough to such junctions.
A syringe for applying adhesive resin to the junctions of racket netting, comprising a reservoir cylinder to contain such adhesive resin and an injecting piston to expel adhesive resin from the reservoir cylinder and four separate, adjacent, parallel, tubular spray nozzles fluidically coupled with and extending from the end of the reservoir cylinder acted upon by the injecting piston, said four spray nozzles being substantially equally spaced around the axis of said reservoir cylinder by a distance approximately corresponding to the diameter of a string of said racket netting to apply substantially identical doses of adhesive resin to such junctions.
