PNEUMATIC-TIRE PLUG.

Original No; 818,402, dated April 24,

To all whom, it mwyconeern:

Bridgeport, in the county: of Fairfieldand- State of Connecticut, have invented certain new and useful Im rovements in Pneumatic- Tire Plugs, of whic cation.

It is the objectof the invention to improve upon (plugs or closers for neumatic tires by provi 1 with a tire ng a deyice com inin an operating tool there or, which in P s itse fcontains a head forconvenienee in manipulation and means for producing an opening in a tire sufiicient to permit the closer to be inserted, which will not injure or cut the tire when in use, to form the closer itself of such shape as to insure its free passage through a" hole in the tire and to further shape the closer to conform to the shape of the tire, thus causing it to press evenly against the same at all oints.

In the accompanying drawin'gforming a part of this s ecification, similar characters of reference enote like parts in the several Figure 1 is a side elevation-of my improved;

plug complete; Fig. 2 a further side elevation of my plug, together with a'portion of a pneu-' matic tire, said in said tire; Fig. 3 a sectional plan view show' the under side of the closer; Fig. 4 a t flinal sectional elevation through the closer; Fi 5 a furthersectional lan view of the un er side of the closer simi ar to Fi 3 but having the flexible washer-remove; Fig. 6 a detached plan view of the ut be longing upon the shank; and Fig. 7 is a crosssectional view of a neumatic tire with my im roved plug attaclied thereto as in use.

iieferrin in detail to the characters of refcrence mar ed upon the drawing, A indicates the closer which, as shown, is of substantiallymember having its edges turn'ed in over the edge of the inner member e and forming an annular beadf, which is slightly broader at the corners p to better avoid wear A trans- Specification of Reislued Letters 1 atent.

verse enlarged socket g is formed centrally of the .closer toreceive a rocker in hand in a central hole of which the re need end i of the threaded shank B is rotatably mounted. A longitudinal slot is formed through the inner section 6 of t 1e closer to allow the shank B to swing forward or backward. The .stock displaced from said slot is deflected outward to form engaging hooks k to secure a flexible washer Z to the under side of the closer, as is clearly shown in the drawing. This washer is formed of rubber, .leather or other soft material, and being placed against the'under sideof the closer serves to engage the inner surface of the tirewhen the closer is shoved through the tire and set back against the inside. This washer prevents the edge of the closer from unduly wearing or cutting the tire, as is the case with some forms of metal lugs. The rockerpin h, mounted in the soc et 9 of the closer, 1s free to turn or rock therein with the swinging movement of the shank, and consequently allows either end of the said closer to be folded back against the shank and with the other end extended, as shown in Fig. 2. In this manner, the closer is inserted through the puncture or opening in the tire and is then swung back or ad usted to substantially aright angle to the shan k and clamped by the nut O. In practice, this nut is run down on the shank against the face of the tire, whereupon the said shank is turned to further draw the nut in against the tire. After said nut is forced up to form attain-tight closure, said threaded shank is bent over and broken ofl even with the face of the nut. The nut, like the-head, is provided with a -rubber or other flexible washer m, which may be cemented thereto. This washer protects the surface of the tire from wear or cutting by the edge of the nut, as is the case With the Washer under the head 'For convenience in manipulation, I provide a head n of the wire stock of the shank, which head is preferably of a triangular shape, having a sharpened end or cutter 0 which can be used for forming an opening in the tire for the closer.

As seen in Fig. -7, the under side of the closer is slightly cpnvexedto better conform to the shape of the tire and to insure its edge bearing equally on the washer which is secured uniformly against the inner side of the tire at all points.

Having thus described my invention, what tached to the nut.

I claim, and desire to secure by Letters Patent, is-

1. A pneumatic-tire plug, comprising a closer having a transverse socket therein, a

shank rotatably mounted in said rocker-pin, and a nut mounted upon said shank.

'2. A pneumatic-tire plug comprising a closer having a transverse socket therein, a rocker-pin mounted in the socket, a threaded shank pivotally mounted in the in, a nut mounted on the shank, and a fiexi le washer secured to the under side of the closer.

' 3. A pneumatic-tire plug, comprising a closer having a transverse socket therein, a rocker-pin mounted in the socket, an annular bead formed on the under sideof said closer, a flexible washer to engage the bead, hooks to securethe washerin place, a threaded shank pivotally connected to the rocker-pin, and a nut mounted upon the shank, substantially as described. r A s. v 4. A pneumatic tire plug, comprising. a

flexible was er attached to said hooks, a threaded shank pivoted to the closer, a nut upon the shank and a flexible washer atf 35 6. A pneumatic-tire plug, comprising a closer convex'ed on its under side to conform to the normal shape of a tire, a threaded shank swiveled to said closer, and a concave nutmounted on said threaded shank.

7. A device of the character described comprising a closer, a threaded shank to which the closer is connected, a nut engaging the shank, a head upon the shank for convenience in manipulation and a cutter for form- 5 ing an opening in a tire for the closer.-

8. A device of the character described, comprising a closer, a threaded shank to which-the closer is connected, a nut engaging the shank, a head for convenience in mampu- 5o lation and meansfor forming an opening in' a tire for the closer.- Signed at Bridgeport, in the county of Fat eld and State of Connecticut, this 7th day of March,- A.
