Abstract
Abstract Apparatus for curing a tire repair wherein an electrical heater pad is placed against the repair area on the inside of the tire, and is supported by a flat air bag which lies against the inside of the tire, and is supported by a sausage-shaped air bag. Another electrical heater pad is placed against the repair area on the outside of the tire, and is held against the tire by another flat air bag which is held against the tire by straps passing around the tire cross-section. A buckle is shown which allows the straps to be pulled up as tight as possible by hand; the bags are then inflated to hold the heater pads firmly against the tire. The repair is then cured by passing currents through the heater pads.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
193 words
Apparatus for use in curing a tire repair, comprising an inner heater pad to be applied to the inside of the tire in the area of the repair, a core to be positioned within said tire to support said inner heater pad against the inside of said tire, an outer heater pad to be applied to the outside of said tire in the area of said repair, a flexible harness to be positioned to extend through the center of said tire and around the outside of said tire in the area of said repair, said flexible harness including a plurality of straps to be positioned around said tire with the center-line of each said strap approximately radial and a buckle including an opening to admit a loop of each strap, said loops being side by side, and a pin to be inserted through said loops, the length of said pin being greater than the combined width of said straps, an inflatable bag to be positioned between said harness and said outer heater pad, means for pressurizing said inflatable bag, and means for heating said inner and outer heater pads to cure said repair.
Claim 2
Dependent Claim
193 words
Apparatus for use in curing a tire repair, comprising an inner heater pad to be applied to the inside of the tire in the area of the repair, a core to be positioned within said tire to support said inner heater pad against the inside of said tire, an outer heater pad to be applied to the outside of said tire in the area of said repair, a flexible harness to be positioned to extend through the center of said tire and around the outside of said tire in the area of said repair, said flexible harness including a plurality of straps to be positioned around said tire with the center-line of each said strap approximately radial and a buckle including an opening to admit a loop of each strap, said loops being side by side, and a pin to be inserted through said loops, the length of said pin being greater than the combined width of said straps, an inflatable bag to be positioned between said harness and said outer heater pad, means for pressurizing said inflatable bag, and means for heating said inner and outer heater pads to cure said repair.
Claim 3
Dependent Claim
27 words
Apparatus as claimed in claim 1 wherein said core includes an inflatable bag, and wherein means are provided for pressurizing said inflatable bag included in said core.
Claim 4
Dependent Claim
67 words
Apparatus as claimed in claim 2 wherein said inflatable bag included in said core is a generally flat bag to be positioned against the inner surface of said tire, and wherein said core includes a further inflatable bag which is elongate and of generally circular cross-section to be positioned within and support said generally flat bag, and wherein means are provided for pressurizing said further inflatable bag.
Claim 5
Dependent Claim
19 words
Apparatus as claimed in claim 3 wherein said core extends around only part of the circumference of said tire.
Claim 6
Independent Claim
152 words
A method for curing a tire repair comprising the steps of: applying an inner heating pad to the inside of the tire in the area of the repair; positioning a core within the tire for supporting said inner heater pad against the inside of the tire; applying an outer heater pad to the outside of the tire in the area of the repair; positioning a harness including a plurality of straps around the tire with the center line of each strap approximately radial; passing a loop of each of said straps through an opening in a buckle whereby said loops are side by side; inserting a pin through said loops, the length of said pin being greater than the combined width of the straps; positioning an inflatable bag between the harness and the outer heater pad; pressurizing the inflatable bag; and heating the inner and outer heater pads to cure the repair.
Claim 7
Independent Claim
152 words
A method for curing a tire repair comprising the steps of: applying an inner heating pad to the inside of the tire in the area of the repair; positioning a core within the tire for supporting said inner heater pad against the inside of the tire; applying an outer heater pad to the outside of the tire in the area of the repair; positioning a harness including a plurality of straps around the tire with the center line of each strap approximately radial; passing a loop of each of said straps through an opening in a buckle whereby said loops are side by side; inserting a pin through said loops, the length of said pin being greater than the combined width of the straps; positioning an inflatable bag between the harness and the outer heater pad; pressurizing the inflatable bag; and heating the inner and outer heater pads to cure the repair.
Claim 8
Dependent Claim
41 words
A method as in claim 5 further comprising the step of positioning another inflatable bag as part of said core within said tire for supporting the same and said step of pressurizing includes the step of pressurizing said additional inflatable bag.
