Device for repair of cracked windshields

Claim 2

Apparatus for the repair of cracks in glass such as windshields utilizing repair liquid injected into said cracks, said apparatus comprising: a. a housing adapted for engaging said glass and having a passage formed therethrough for receiving said repair liquid; b. means for engaging the glass and defining a first enclosure, said means comprising a diaphragm having a first peripheral sealing lip and a second inner sealing lip defining a first area of said first enclosure therebetween; c. means for evacuating said first enclosure for producing a vacuum therein, said evacuating means being removably attached thereto; d. means for maintaining said vacuum in said first enclosure when said evacuating means is removed; e. a second enclosure defined by said inner sealing lip and completely isolated from said first enclosure, said second enclosure being in flow communication with said passage; and f. a piston, movable within said passage, for pressurizing and evacuating said second enclosure.

Claim 3

An apparatus according to claim 1 in which said first peripheral sealing lip completely surrounds the peripheral of said diaphragm.

Claim 4

An apparatus according to claim 1 in which said second enclosure is in the center of said first enclosure.

Claim 5

An aapparatus according to claim 1 in which said passage is cylindrical and extends axially from the exterior of said housing to said second area immediately surrounding said cracks.

Claim 6

An apparatus according to claim 1 in which evacuating means for said first enclosure comprises a hand pump.

Claim 7

An apparatus according to claim 1 in which means for maintaining vacuum in said first enclosure comprises a steel ball situated between a steel roll pin and an O-shaped ring in an enclosure assembly connecting a vacuum inlet and vacuum path.

Claim 8

An apparatus according to claim 1 in which said diaphragm further comprises a plurality of arcuately shaped ribs in concentrically aligned relationship with said second inner sealing lip.

Claim 9

An apparatus according to claim 7 in which said diaphrgam further comprises a first peripheral sleeve, a second central sleeve and a third side sleeve.

Claim 10

Apparatus for the repair of cracks in glass such as windshields utilizig repair liquid injected into said cracks, said apparatus comprising: a. a generally cylindrical housing adapted for engaging said glass and having a central passage formed therethrough for receiving said repair liquid; b. a base on said housing having a neck region formed therearound, said central passage extending axially from the exterior of said housing through said base; c. means for engaging the glass and defining a first enclosure, said means comprising a diaphragm encapsulating said base having a first peripheral sealing lip and a second inner sealing lip defining a first area of said first enclosure therebetween; d. means for evacuating said first enclosure for producing a vacuum therein, said evacuating means being removably attached thereto; e. a one-way valve disposed in said housing adjacent said base for one-way flow communication with said evacuating means; f. a second enclosure defined by said inner sealing lip and completely isolated from said first enclosure, said second enclosure being in flow communication with said central passage; and g. a piston movable with said central passage for pressurizing and evacuating said second enclosure.

Claim 11

Apparatus for the repair of cracks in glass such as windshields utilizig repair liquid injected into said cracks, said apparatus comprising: a. a generally cylindrical housing adapted for engaging said glass and having a central passage formed therethrough for receiving said repair liquid; b. a base on said housing having a neck region formed therearound, said central passage extending axially from the exterior of said housing through said base; c. means for engaging the glass and defining a first enclosure, said means comprising a diaphragm encapsulating said base having a first peripheral sealing lip and a second inner sealing lip defining a first area of said first enclosure therebetween; d. means for evacuating said first enclosure for producing a vacuum therein, said evacuating means being removably attached thereto; e. a one-way valve disposed in said housing adjacent said base for one-way flow communication with said evacuating means; f. a second enclosure defined by said inner sealing lip and completely isolated from said first enclosure, said second enclosure being in flow communication with said central passage; and g. a piston movable with said central passage for pressurizing and evacuating said second enclosure.

Claim 12

An apparatus according to claim 9 in which said on-way flow communication is accomplished by an enclosure assembly comprising a steel ball situated between an O-shaped ring and a steel roll pin in said enclosure assembly connecting said vacuum inlet and said vacuum path.

Claim 13

An apparatus according to claim 9 in which said circular diaphragm further comprises: a. a plurality of arcuately shaped ribs in concentrically aligned relationships about said second inner sealing lip; b. a first peripheral sleeve encircling shoulder of said base; c. a second central sleeve projecting into said central passage; and d. a third sleeve encircling said one-way valve, said third side sleeve comprises an O-shaped ring around the top of said side sleeve.
