To all whom, it may concern:

Be it known that I, ABRAHAM I. LEVIN, a citizen of the United States of America, residing at Far Rockaway, Q eens County,

State of New York, have invented certain new and useful Improvements in Rim Liners, of which. the following is a specifica- .tion.

This invention relates to a rim liner and in particular to one which is used onthe outer face of a metal rim felly to aflord a protection to the inner-tube.

A particular object of the invention is to provide a rubberized fabric strip which may have adhesive qualities and which is used to line the outer peripheryeof the metallic rim used on pneumatic tire wheels to prevent rusting of the rim.

A further object is to provide a liner of the character described which will adhere to the inner periphery of the tire casing or I we shoe to close the opening therein, into which the tube has been inserted so that the tube is protected not only from rubbing against the metal rim but also from creeping rela tively to the shoe in which it is encased therebyreducing wear of the tube. The adhesive side of the liner may be'applied to the rim directly.

A further object is to provide-a seal for the casing or shoe so that no dirt, grit or rust can obtain access to the tube to cause puncture or Wear thereof-.-

A further object of the invention is to provides. linerlwhich is waterproof, which will protect the tube from'rubblng or bearing on the rim which may become rusted after dampness, and which will have a tendency to prevent r elative creeping between the shoe and the rim.

A further object is to provide a liner, the ends of which will be vulcanized'together by the heat generated in the tire when the wheel is revolving; thus preventing its working loose and consequent dragging from the wheel."

In the drawings wherein one embodiment of my invention is illustrated Fig. 1 is a perspective view of my liner opened out and shows the construction of one end thereof where it passes over the valve stem when applied to a rim, showing also in dotted lines the strip when rolled up.

- Fig. 2 is a section through a tire,.and rim therefor showing the position of my rim liner in place, the section being taken to show the valve and relative location of san .liner; and, f

partial longitudinal section.

Fig. 3 is a greatly enlarged through the liner at the end thereof, which fits over the valve stem and the strip is faced with a short piece of canvas or suitable fabric 7, as illustrated in Fig. 3, the same extending beyond the opening 8 in the liner. This opening is provided to allow for the passage therethrough of the valve stem 9 which projects from the usual inner tube 10 and through the rim 11.

The facing piece 7 extends beyond the extreme end of the liner. and. exposes on the under side thereof, a portion of the adhesive surface of said piece 7. In a plying the liner the same is passed aroun the rim of the wheel with the adhesive surface up and the opening 8 therein matchin the opening in the rim. The opposite on of the liner which has been brought around the rim is insertedunder the overhanging portion of the piece 7 so that the two adhesive surfaces are together, then the tire is put on in the usual manner and the inner periphery of the shoe will rest on the adhesivesurface of the liner and will, during the running of the car become very tightly'fixed thereto. The heatgenerated by the running of the car will vulcanize the lower side of the iece 7 to the end of the liner with whichit contacts, as explained above, so that the ends of the liner will be bound firmly together and will be prevented from leaving the wheel by accident. It will be further noted that the both sides of the liner or canvas may be provided with the adhesive surface so that the liner will also adhere to the rim as well as the shoe. This adhesive substance is'of a rubbery nature and excludes moisture so that occur to the inner tube due to its rubbing on the face of the rim.

It will therefore be seen that I have provided a liner which will prevent dust and grit from entering the tire casing. It will lessen the liability of puncturing the .inner tube.

It is to be understood that the liner may be applied with the adhesive side against the rim periphery, thereby preventing moisture from getting to the rim and rusting same, which usually causes excess wear and puncture of the inner tube.

What I desire to secure by Letters Patent A rim liner consisting of a fabric band, adapted to be placed around the rim of a Wheel, .the ends of said band beingadapted to be joined and held together by an ad-- hesive substance, and one of said ends be- 20 ing reinforced.

ABRAHAM I. LEVIN.
