TIRE-SHOE a Specification of Letters Patent.

v Application-filed November 4, 19 18. Serial No. 260,979.

This invention relates to new and useful improvements in a tire shoe. I

The object of the invention is to provide a shoe of the character described which is designed to be placed around the inner tube of a pneumatic tire opposite a blow-out, or a-weak place in the casing, so as to strengthen the casing and prevent the inner tube from being burst or blown-out.

Another object of the invention resides in the provision of a shoe of the character described which may be securely fastened around the inner tube before it is placed in the casing, and which will be securely held in position against slippage or displacement.

A further feature of the invention resides in the provision of a flexible detachable strip forming a part of the shoe and interposed between the inner tube, and the free edges of the shoe, which prevents the tube from becoming pinched between said free edges, and includes means for securing said flexible detachable strip in position.

With the above and other objects in view, the invention has particular relation to certain novel features of construction, arrangement of parts, and use, an example of which is given in this specification, and illustrated in the accompanying drawings, wherein:

Figure 1, is a side elevation of the shoe.

Fig. 2, is a view of the inner side thereof.

Fig. 3, is a transverse sectional view of a tire casing and tube showing the shoe within the casing, and

Fig. 4, is a plan view of a flexible material employed.

Referring now more particularly to the drawings wherein like numerals of reference designate similar parts in each of the figures, the numeral 1, refers to a pneumatic tire casing, having the inner inflatable tube 2 therein. In case a blow-out 3, occurs, in.

the casing, or it becomes otherwise weakened at any particular place, the shoe 4 is fitted around the tube which is then placed in the casing so as to bring the shoe opposite said blowout. This shoe is formed of strong rubberized fabric, or other strong flexible material, and its free edges are provided with eyelets 5, to receive the lace 6, by means of which the free edges of the shoe are laced together around the tube from end to end. For the purpose of protecting the tube against coming in' contact with the lace 6, or becoming pinched between the free edges of the shoe, I have interposed between said tube and the lace a long strip of flexible detachable material, preferably rubberized fabric, built up of a plurality of plies as 7,

8 and 9, each ply being somewhat narrower than the preceding one, as shown in Figs. 3 and l, and the lace passes between said plies 8 and 9 at a sufficient number of points to secure the strip in position, as is also shown in Fig. 3. The tire may be then placed upon the rim and completely inflated. The shoe is thus held firmly in position and will not work circumferentially around the casing and the protecting detachable strip interposed between the inner tube and the lacing is held securely in position. It is obvious that a shoe similar to this may be placed over a. blowout and laced onto the casing to strengthen the weakened part. In case this is done, the flexible strip is not used.

What I claim is:

In a device of the characterdescribed, the

combination with an outer casing and an Patented Apr. 1, 1919.

inner inflatable tube, of a shoe formed of flexible material and fitted Within the casing, and surrounding said tube, each of the free edges of the shoe being provided with perforations, a protecting strip formed of layers of flexible mateiial, fitted between said inner tube and the free edges of said shoe, each layer being narrower than the HENRY E.
