HENRYA. RUDD, OF BARBERTON, OHIO, AssIGNoR 0F ONE-HALF TO MICHAEL PABIDON, OF BARBER'ION, OHIO.

rNEuMATIc-rtnr. SHOE.

To all whom it may] concern:

Be'it known'that I, HENRY A. 'RUDD, a

citizen of the United States, residing at Barberton, in the county of Summit and' State of-Ohio, have inventednew and useful Improvements in Pneumatic-Tire Shoes, of

'which the following is a' specification.

tions thereof.

- The object of the invention is to provide an improved core adapted for incorporation within the bead of a pneumatic-tire-shoe which will strengthen the 'same and serve as a means for spacing the cords from wh ch a tire-shoe may be'constructed.

I It is contemplated as a further object'that the device'is especially applicable for use in a tire-shoe wherein the strength-giving properties of the shoe comprise one or more layers of cord to form what is commonly known as a cord-tire. 7 Another object of the invention is to provide a core for beads for use in pneumatic-tire-shoes provided with a pair of antrated in the accompanying drawings which form a part hereof wherein is shown the preferred embodiment of the invention, but

it is to be understood that changes, vari ations and modifications can be resorted to which come within-the scope of the matter hereinafter claimed.

In the drawings in which similar reference numerals indicate like parts in the different figures, Figure 1, is ,a transverse sectional view of the bead-portion of atire shoe embodying this invention. Fig. 2, is a side elevation of a bead-core embodying this invention. Fig. 3, is a perspective view of the core shown in Fig. 2, and Fig. 4;, is a 1 7 Specification of Letters Patent.

"view partially in section andpartially in side elevationof so much of the bead portion of apneumatic-tire-shoe as will illusp trate the present invention.

The core which formsthe subject matter of this invention compr ses two annularly formed members or'rings 1 and 2 provided with registering openings through which are extended clamping or holding members, such ,for instance as rivets 3. The inner faces ofthe two members" land 2 are provided with teeth or notches fl providing between themspaces 5 for a purpose to be later described Interposed between the two'members :1 and 2 is a body member of fibrous materialsuch 'as'cloth 6 which may be arranged in'successive layers "or otherwise but preferably so fashioned as to be wedge-shaped in cross section asshow'n in Figs. 1' and 3. This cloth will ordinarily be impregnated with a vulcanizable gum portions of the tire-shoe when the shoe is 4% constitute retaining means for the cords 7 compound so as to adhere to the 'cord vulcanized. The notches between the teethv of which the body portion of the tire-shoe foutwardly to the tread as shown in Fig. 4,

but of course, usually at an angle 'approximating 45 degrees to the longitudinal line of the shoe to form -a single layer. The convolution's of cords 7 about the core formedby the members 1,2, and 6 will form the base or nucleus of'thehead of thetire- 5 about which other head material. may be employed as shown in Fig. 1.. By mak: 1

ing the members 1 and 2" of relatively .thin material and clamping them against the fibrous material 6 which is relatively thin and containing a vulcanizable material tlie two layers of cords forming the body portion of the tire .will be bro gh closely together and the cords or members whichform the strength-giving properties of the tire will unite with the fibrous members 6' during. vulcanization and hence no gaps or. openings will exist between the two layers ,of cords outside of the reinforcing core members 1 and 2 and all portions; of the body of the shoe will hence be intimately united which would not be true if the interposed layer of material 6 was not employed.

In ordinary practice if a reinforcement or core is provided'in the bead portion of the shoe and strength-giving cords are arranged as shown in Fig. 4 the portions of the cords immediately outside of the core will always remain in'spa'ced relation thereby providing an air space, which prevents adhesion or close contact of the two layers of the body portion of the'shoe. The space between the two layers immediately outside of the core is a source'of weakness which is entirely eliminated by the. use of a core forming the present invention, the interposed strip .of fibrous material 6 serving to fill this space and affording means to which the two layers of cords are intimately united during vulin-extensible bands adapted to be connected by transversely-extending members and an interposed fibrous band extend ng in a c1rcumferential direction only between them,

and held in position thereby.

3. A reinforcement adapted to e incorporated in the bead portion of a pneumatictire-shoe comprising a pair of metallic rings between which is interposed an outwardly projecting ring of fibrous material impreg nated with a vulcanizable compound, and fastening means extending between said metallic bands for holding said fibrous band in position.

4. A reinforcement for pneumatic-tireshoe beads comprising a pair of ring-shaped metallic bands, an interposed annular band of'tfibrous material impregnated with a vulcaii'izable compound, clamping means extending between said metallic bands for clamping said bands against said fibrous band.

5. A reinforcing core for a bead of a pneumatic-tire-shoe comprising two ringshaped bands of inextensible material and a band of fibrous material interposed between them and projecting outwardly therefrom, means extending through said bands for holding them in assembled relation.

6. A reinforcing core for a head of a 'pneumatic-tire-shoe, comprising two ringshaped bands of inextensible material, a band of fibrous material interposed between them and projecting outwardly therefrom and means extending through said bands for holding them in assembled relation, the inner faces of said inextensible bands provided with a circumferentially-extending series of notches. 1

7. A reinforcing core for use in connec} tion with a bead of a pneuinatic-tire shoe which comprises two inextensible' bands at ranged in spaced relation, an interposed band of fibrous material, means for clamp-v ing said inextensible bands on said fibrous band, said inextensible bands each provided on their inner faces with a circumferentially-extending series of notches.

8. A reinforcing core for use in. connec-.

bead portion thereof a pair of annularlyfashioned reinforcing elements of inextensible material, an annular band of fibrous material wider than said elements interposed between them, and coupling means for clamping said elements against opposite faces of said fibrous band.

In testimony whereof I have hereunto set my hand.
