Abstract A method and apparatus for sealing and reinflating a dead tennis ball. A latex sealant with asbestos fibers suspended therein is injected into the tennis ball by means of a needle and a hypodermic syringe. The syringe is then disconnected from the needle and the needle is connected to a pressurizing device such as a hand pump. After pressurizing the tennis ball to approximately 15 pounds per square inch, the needle is removed from the tennis ball and the tennis ball is rotated to insure an even coating of the sealant on the inside thereof. The tennis ball is then immersed in water to determine any points through which air may be leaking from the ball. These points are then rotated to the bottom of the tennis ball to insure that sufficient sealant will stop the air leaking from the tennis ball. By the time the sealant takes effect, the pressure inside the tennis ball is approximately nine pounds per square inch. The tennis ball is then cleaned and dried.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
An apparatus for sealing and reinflating a dead ball, said apparatus comprises: a sealant; a hollow needle having a sharpened end for penetrating the wall of said ball; means detachably connectable to said needle for injecting said sealant through said hollow needle into said ball; a source of pressurized air; a conduit having one end thereto connected to said source of pressurized air; means for detachably connecting the other end of said conduit to said hollow needle after said injecting means has been detached therefrom so that said ball may be pressurized by said source of pressurized air through said hollow needle after said sealant has been injected into said ball.
Claim 2
Independent Claim
111 words
An apparatus for sealing and reinflating a dead ball, said apparatus comprises: a sealant; a hollow needle having a sharpened end for penetrating the wall of said ball; means detachably connectable to said needle for injecting said sealant through said hollow needle into said ball; a source of pressurized air; a conduit having one end thereto connected to said source of pressurized air; means for detachably connecting the other end of said conduit to said hollow needle after said injecting means has been detached therefrom so that said ball may be pressurized by said source of pressurized air through said hollow needle after said sealant has been injected into said ball.
Claim 3
Dependent Claim
19 words
The apparatus as recited in claim 1 wherein said injecting means is a syringe connectable to said hollow needle.
Claim 4
Dependent Claim
48 words
The apparatus as recited in claim 2 wherein said source of pressurized air is a pump for reinflating said ball so that pressure inside said ball is approximately 9 pounds per square inch upon said stopping of said leaks by said sealant, said ball being a tennis ball
Claim 5
Dependent Claim
24 words
The apparatus as recited in claim 2 further comprises metering means for measuring the pressure inside said tennis ball before removing said hollow needle.
Claim 6
Dependent Claim
47 words
The apparatus as recited in claim 4 further comprises a fluid for submerging said tennis ball to determine the point of leaks therein so that said leaks may be coated with said sealant by rotating the point of said leaks to the bottom of said tennis ball.
Claim 7
Dependent Claim
20 words
The apparatus as recited in claim 1 wherein said sealant is a latex substance with an asbestos fiber suspended therein.
