Abstract
Abstract This invention is directed to an apparatus and method for repairing pock marks and bullseyes in glass such as a windshield and such as plate glass. The apparatus comprises essentially an adapter, a syringe and a polymerizable resin. The adapter is attached to the glass over the pock mark or bullseye. The syringe with the polymerizable resin is positioned in the adapter and the polymerizable resin forced into the pock mark or bullseye.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
161 words
An apparatus for injecting a liquid repair material into a crack in glass, said apparatus comprising: a. an adapter; b. said adapter having a first end and a second end; c. said adapter having a large circular recess in said first end and a small circular recess in said second end; d. said large circular recess and said small circular recess uniting to form a passageway and to define a shoulder at their junction; e. a syringe having a barrel, a tip and a movable plunger in said barrel and said liquid repair material being in said barrel; f. said tip of said syringe being in said small circular recess and bearing against said adapter to be positioned in said adapter and juxtapositioned to said second end for allowing said liquid repair material to flow from said syringe and from said tip to said glass; and, g. a bonding means for bonding said second end of said adapter to said glass.
Claim 2
Independent Claim
161 words
An apparatus for injecting a liquid repair material into a crack in glass, said apparatus comprising: a. an adapter; b. said adapter having a first end and a second end; c. said adapter having a large circular recess in said first end and a small circular recess in said second end; d. said large circular recess and said small circular recess uniting to form a passageway and to define a shoulder at their junction; e. a syringe having a barrel, a tip and a movable plunger in said barrel and said liquid repair material being in said barrel; f. said tip of said syringe being in said small circular recess and bearing against said adapter to be positioned in said adapter and juxtapositioned to said second end for allowing said liquid repair material to flow from said syringe and from said tip to said glass; and, g. a bonding means for bonding said second end of said adapter to said glass.
Claim 3
Dependent Claim
26 words
An apparatus according to claim 1, said apparatus comprising: a. the end of said tip of said syringe extending to said second end of said adapter.
Claim 4
Dependent Claim
13 words
An apparatus according to claim 1 and comprising: a. said adapter being deformable.
Claim 5
Independent Claim
260 words
A method for injecting a liquid repair material into a crack in glass, said method comprising: a. positioning an adapter over said crack in said glass; b. said adapter having a first end and a second end; c. said adapter having a large circular recess in said first end and a small circular recess in said second end; d. said large circular recess and said small circular recess uniting to form a passageway and to define a shoulder at their junction; e. bonding said second end of said adapter to said glass with a bonding means with said small circular recess of said adapter positioned over said crack in said glass; f. positioning in said passageway a syringe having a barrel, a tip and a movable plunger in said barrel and said liquid repair material being in said barrel with said tip of said syringe being in said small circular recess and bearing against said adapter to be positioned in said adapter and juxtapositioned to said second end for allowing said liquid repair material to flow from said syringe and from said adapter to said glass; g. bonding said adapter to said glass with a bonding means to prevent the flow of said liquid repair material between said adapter and said glass and also to prevent the flow of gas from outside said adapter to said crack in said glass; and, h. moving said plunger in said barrel to force said liquid repair material to flow through said tip and through said adapter and to said crack in said glass.
Claim 6
Independent Claim
260 words
A method for injecting a liquid repair material into a crack in glass, said method comprising: a. positioning an adapter over said crack in said glass; b. said adapter having a first end and a second end; c. said adapter having a large circular recess in said first end and a small circular recess in said second end; d. said large circular recess and said small circular recess uniting to form a passageway and to define a shoulder at their junction; e. bonding said second end of said adapter to said glass with a bonding means with said small circular recess of said adapter positioned over said crack in said glass; f. positioning in said passageway a syringe having a barrel, a tip and a movable plunger in said barrel and said liquid repair material being in said barrel with said tip of said syringe being in said small circular recess and bearing against said adapter to be positioned in said adapter and juxtapositioned to said second end for allowing said liquid repair material to flow from said syringe and from said adapter to said glass; g. bonding said adapter to said glass with a bonding means to prevent the flow of said liquid repair material between said adapter and said glass and also to prevent the flow of gas from outside said adapter to said crack in said glass; and, h. moving said plunger in said barrel to force said liquid repair material to flow through said tip and through said adapter and to said crack in said glass.
Claim 7
Dependent Claim
25 words

Claim 8
Dependent Claim
15 words
A method according to claim 4 and comprising: a removing said adapter from said glass.
Claim 9
Dependent Claim
46 words
A method according to claim 4 and comprising: a. removing said adapter from the vicinity of said crack of glass and from said glass; and, b. finishing said glass in the area of said crack of glass and said repair material to present a finished appearance.
