Abstract: The flat tire repair kit at present on the market contains band rubbers, a tube of super glue and a needle. It is very troublesome to repair a flat tire because the flat tire has to be removed from wheel before it can be repaired by the repair kit on market. Besides it is very hard to insert the band rubbers into nail hole with needle. The present invented barrel formed screw or barrel formed nail can repair flat tire while it is still on wheel. After applying super glue to the present invented barrel formed screw or barrel formed nail user can screw or hammer it into nail hole on flat tire while it is still on wheel. The form of barrel formed screw or barrel formed nail prevents it from coming loose. The submitted picture demonstrates only one of the possible drive design, which is a cross-shape. Barrel formed screw or barrel formed nail can be used temporarily to repair a flat tire before the nail hole can be repaired by a machinist at auto body shop.

Abstract: A repair apparatus for tire punctures is operable upon a damaged tubeless tire in situ and includes a hollow probe initially containing a rubber boot disposed in a collapsed condition but subsequently automatically unfolding when urged into the tire interior by a plunger rod in the probe. A stem integral with a circular main body of the rubber boot is connected to the plunger rod by a flexible tether that serves to retain the unfolded boot juxtaposed the puncture point inside the tire while a drive rod forces a measured amount of rubber bonding fluid through the probe to sealingly secure the boot. Alignment and retention of the probe and drive rod is facilitated by a mounting unit secured to the tire by adjustable attachment elements clampingly engaging the rim of the wheel mounting the tire while threads on the probe and drive rod cooperate with tapped bores in the mounting unit to permit controlled advancement and retraction of the probe and drive rod.

There is provided a tool having a handle portion and adjoining slender shank portion for forcibly inserting the plug into a puncture.

Abstract: A repaired elastomer article having a cut or crack entirely therethrough. A treating agent is located about the cut portion on the inner surface of the article and an amine curable polymer or prepolymer layer resides over said treating agent. A cured elastomeric patch resides over said curable polymer. Since the amine curable polymer cures at ambient temperatures, the repair of the elastomer article can occur on site. The invention is especially useful in the repair of tires.

Abstract: A repaired elastomer article has a hollow in a non-reinforced portion of the article. A cured preformed plug resides within the hollow and is adhered to the article through an amine curable polymer or prepolymer. The amine polymer or prepolymer is curable at ambient temperature. The preformed plug is made of a material which is compatible with the elastomer of the article. The preformed plug material desirably has a lower modulus than the elastomer of the article and hence exhibits good physical properties such as enhanced longevity of the repair, good wear and the like. Since the amine curable polymer or prepolymer cures at ambient temperatures, the repair of the elastomer article can occur in situ. The invention is especially useful in the repair of tires.

When the shank portion is forcibly engaged with a puncture, the sealing rings individually radially compress and locally conform to the size and shape of the puncture thereby providing multiple sealing members with the puncture. Additional sealing is provided by an auxiliary sealing ring on the head portion of the closure which is adhesively bonded to the inner surface of the tire, adjacent to the puncture. Tool attaching means are provided on the closure for forcibly engaging the closure with the puncture.

Abstract: A tool tip is inserted from the inside of the tire into a hole in a tire crown by turning the tool tip as it is pressed against the tire. The tool tip is mounted on a hollow tool having a cylindrical insert receiving chamber. An insert is pushed by a plunger out of the receiving chamber in the hollow tool through a tapered portion into a compression chamber in the tool tip. The compression chamber has a diameter smaller than the diameter of the insert so that when the insert is ejected from the hollow tool it will expand to fill the hole in the tire. The insert is also tapered to engage the tapered portion between the receiving and compression chambers. The plunger has a plunger head with a substantially flat pushing surface and knurled edges which the operator can manually grip and push.

Abstract: The repair of a reinforced elastomer article having a hollow therein relates to utilizing an amine curable polymer or prepolymer and a cured elastomer patch. The hollow in the elastomer, which can extend either partially or completely through the article, is filled with a gum rubber which is thereafter cured by conventional means, such as with spotters. The area beneath the now filled hollow is coated with a treating agent, followed by the amine curable polymer or prepolymer and a cured patch. The polymer is then cured at room temperature. One area of use is in the repair of tires.

Abstract: A tire repair patch having at least one ply package enveloped by an unvulcanized base cushion gum layer and an unvulcanized top cushion gum layer joined at the edges of the ply package. The overlapping plies of reinforcing cords in the ply package are coated with rubber and are at least partially vulcanized prior to assembly of the patch to increase the strength of the patch and decrease the curing time upon application to a tire.The patch is made by coating the plies with rubber, laying the plies one on top of the other to form the ply package, heating the package to cure the rubber coating and then positioning the ply package between the unvulcanized cushion gum layers. An unvulcanized intermediate cushion gum layer may be positioned between two ply packages where there is more than one ply package in the patch.

Abstract: A repair construction and method are disclosed for repairing a damaged portion in the wall of a tire. A patch is installed over the damaged portion on the inside of the tire, and the inside of the tire is pressurized to force the patch into the damaged portion, preferably in a concave shape. The remainder of the plug area then is filled on the outside of the patch with a suitable plug material, and the plug material and patch are then cured while the patch is maintained in position at least partially within the damaged portion. This construction and repair method eliminates bulging on the exterior of the tire after the repair is completed.

Abstract: A tire sidewall repair patch having overlapping plies of reinforcing cords positioned in the patch. An inner margin of the patch has a concave edge which conforms generally to the shape of a bead portion of a tire. The side edges are connected to a generally convex outer edge to reduce edge pulling. The reinforcing cords are concentrated in the central portion adapted to cover the tire injury. Flexibility of the side portions at the inner margin is provided by reducing the number of plies extending into the side portions.

Abstract: An inside repair for tubeless tires is provided wherein a measured amount of an air (or moisture) curing elastomeric adhesive is applied to the cleaned and primed inner surface of the tire over the puncture hole, a porous path is placed over the adhesive and the adhesive is then forced into the puncture hole by use of a cup-shaped tool lined with a release material. After the material has cured sufficiently to form a substantial skin, the tire is inflated. Thereafter, the repair cures fully with the tire in the strained condition of inflation. The elastomer is of low durometer and is compatible for adhesion to rubber.

Abstract: A tire repair patch having overlapping plies of reinforcing cords, a base cushion gum layer and an intermediate cushion gum layer positioned between at least two of the plies.
