PN EU MATIC-TIRE REPAIRER.

SPECIFICATION forming part of Letters Patent No. 650,910, dated June 5, 1900.

Application filed September 18, 1899. Serial No. 730,868. (No model.)

To all whom it may con/cern:

Be it known that I, GEORGE READING, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Pneumatic-Tire Repairer, of which the following is a specification.

My invention relates to repair-kits for repairing tires, and has for its object. to provide an improved plug and means for inserting and securing it in the tire, so that the puncture or hole will not be materially increased.

With this object in view my invention consists in the parts and combination of parts, as will be fully described hereinafter, illustrated in the accompanying drawings, and recited in the claims, all forming a part of this specification. j

In the drawings, Figure 1 is a sectional view of a tire of any approved construction, showing the manner of inserting the plug therein. Fig. 2 is a vertical longitudinal section of the plug. Fig. 3 is a top plan view of the same. Fig. 4 is a side elevation of the tool for inserting a modified form 0f plug. Fig. 5 is a vertical longitudinal section of the cement-applying receptacle. Fig. 6 is a side elevation of the tool for inserting the plug shown in Fig. 2. Fig. 7 is a side elevation of the cutter for making thesidey walls of the puncture smooth and even before inserting the plug, and Fig. 8 is a vertical 'longitudinal section of a modified form of plug.

Referring now to the drawings by referencenumerals, 8 represents the cutter for cutting the edges of the opening caused by some sharp object which has punctured the tire and has a cutting edge 9 at its lower end.

l0 represents the cement-holding receptacle, comprising the hopper-like portion l1, contracted at 12 to form a tube, which terminatesin a right-angular extension 13, pointed at its end and having a series of openings or perforations 14 at its upper edge through which the adhesive material may be forced.

15 represents the plug employed in connection with my repairkit and consists of a concavo-con Vex bottom 16, provided with a concentrically arranged upwardly projecting stem 17, on the end of which is secured a flexible cord of any desired length. Secured to or molded integral with the top edges of the bottom portion 16 is a lIiat top or cover 18, having a tubular projection 19 extending from its center in line With and of about the same diameter as the stern 17. This plug will be made of thin rubber, in order that the top and bottom portions may be brought together, as will be hereinafter explained. The stem 17 4is' preferably made longer than the distance from'the bottom to the top of the plug, s0 that its top will normally be forced over to one side, as shown in Fig. 2, out of the Way of the ipserting-tool. The tip of the stem is preferably formed tapering or Wedge-shaped for the reception of the flexible cord and also to cause it to readily enter the tubular projection 19.

The inserting-tool consists of an elongated piece of wire 20 of sufcient gage to insure rigidity, provided with an eye at one end and a right-angular roughened projection 21 upon the other.

The plug will be applied as follows: Cement being placed in the receptacle provided for that purpose the contracted portion thereof is then inserted in the opening in the tire. The right-angular extension is then turned around inside the tire while the cement is being forced through the perforations until a sufficient amount is distributed over the inner surface of the tire. The cement-receptacle is then withdrawn, and after inserting the plug by the tool described the tool is withdrawn and the projections are pulled through the opening made in the tire. When the plug is used in the form shown in Fig. 2, a sufficient amount of cement will be inserted through the tubular projection to insure the bottom and top being cemented together.

In the modified form of my kit a plug similar to the one shown in Fig. 8 will be employed, comprising the concavo-convex disks 25, having a stem 26. In inserting this form of plug a tool such as is shown in Fig. et will be used. This tool comprises a rigid mem# ber 27, reduced at one end and at the other having an elongated recess 2S to hold cement and a channel 29, through which it is forced into the tire by means of the plunger 30. Intermediate the ends .of this member are provided ears 81, to which a pivoted member 32 is secured, and the lower'ends of the two members are normally held in contact by a spring 33. Each member is provided with IOO a cut-out portion 34 for the exit of the cement, and their ends are concave to coliform to the stein of the plug.

In inserting the last-named plug the steni is grasped between the two lower concave ends of the pincers formed by pivoting these members together and inserted in the usual manner until the channel 29 is adjacent to the inner wall of the tire, when the plunger is forced down and the cement is forced through. The pincers are then withdrawn, and the plu g will adhere to the tire similar to those now in use.

In both processes the tires are inflated in the usual manner, which will have a tendency to assist the plug to remain against the wall of the same until the cement hardens.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

l. In a bicycle-tire repairer, the combina tion, with a hollow plug having a convex bottom and a iiat top, the top being provided with a centrally-located tubular projection and the bottom being provided with a stem in alinement with the projection, and of a larger diameter than the bore of the same, the upper end of the stem being tapered, of a flexible cord secured to the tip of the stem and extending through the projection, substantially as described.

2. In a bicycle-tire repair-er, the combination, with a hollow substantially-semispherical plug, the top of which is provided with a centrally-located tubular projection and the bottom is provided with a stem upon the interior in alinelneut with the projection, of a cord secured to the plug and extending through the tubular projection, and an insertion-tool, the outer end of which is provided with a handle and the inner end is bent into a laterally-extending roughened projection for engaging with the inner surface of the fiat top to rotate the plug upon the interior of the tire, substantially as described.

GEORGE READING.
