Appicaton filed I une 1515.

To aZZ whom it may concern:

Be it known that l, SEYMOUR A. Rouse,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful improvements in Armored Liners for Pneumatic Tires; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to armored reliners for insertion into pneumatic tires, and the primary object of the invention is to pro# vide an armored liner, which is practically puncture-proof, and one which is rendered practically puncture-proof by insertion of a plurality of connected metallic disks within the tread section thereof, for preventing nails, or other foreign articles from penetrating through the inflatable inner tube of the tire, and also for eliminating the liability of blow-outs.

lAnother object of this invention is to connect the disks which are inserted or embedded in the liner, in relatively spaced relation to veach other for facilitating the forming or building up of the liner, and further to copperize the disks so that they ma;7 be securely attached to the rubber and fabric portions of the reliner by vulcanizfinother object of this invention i, to em- `boss the disks so as to prevent them from slipping or shifting out of their proper positions should the vulcanizing be imperfect.

Vith the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fullydescribed, illustrated in the accompanyinfr drawings and ciailned.

- In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like or corresponding parts throughout the several views, and in which Figure l is a cross sectional view through a tire shoe, showing the liner inserted therein,

Fig. l() is a cross sectional view of the disks shown in Fig. 9.

Referring more particularly to the draw-- ings, l designates the completed liner, as an entirety, which is shaped to fit the interior of a tire shoe of ordinary construction. rlhe reliner is adapted for being cemented within the shoe, Vas indicated at 2 in Fig. l of the drawings, for protecting the inner inflatable tube 3. The reliner l is armored for preventing the puncturing of the inner in flatable tube 3, by means of a plurality of disks 5. The disks are formed in sheets and extend about the entire circumference of the reliner, being held in relatively spaced relation to each other by means of tongues ,6. The reliner l has two Asheets of disks ``einbedded therein, which .are spaced from each other, and the disks are positioned for overlapping each other, for forming substantially a solid metallic casing within the reliner, thereby reinforcing the tire and rotecting the tube 3 against puncture, boww outsor the like.

in Fig. of the drawings, a sheet disks is shown, wherein the central row 8 of the disks are tied or connected longitudinally of the sheets, by tongues 9. The side rows i0, l1. 12 and 13 of the disks are connected to the central row 8, hv laterally exten/ding tongues lli and '15. lThe disks in the side rows l0, il, i2 and 13, are connected for forming laterally extending connected rows of disks, which `facilitate the bending of the sheet of disks -for conforming to the-configuration of the tire, and also add to the esiliency of the sheet` of disks during the o erationY of the" |The disks in the outermost side rowce'l and 'i3 are narrower than the disks in the side rows 10 and il, and the latter disks are tio narrower thanthe disks inthe central row S, the disks gradually decreasing in width as they extend outwardly from the central row ofl disks.

In Fig. 5 of the drawings, a slightly modified form of the sheet of disks is shown, wherein the two central rows 16 and 17 are tied or connected longitiulinally of the sheet by tongues 18 and 19. The side rows of the sheet illustrated in Fig. 5, are tied or connected to the two central rows 1G and 17 by hiterally extending tongues 20, and the outermost side rows are connected to the side rows 21 and 22, which are connet ed to the central rows 16 and 17, by tongues The disks in the outermost row are narrower than the disks in the rows 21 and 2Q, which latter disks are also narrower than the disks in the central rows 1G and 17, as shown in Fig. G.

1n Figs. 9 and 10 a modified form of the embossed disks is shown, which illustrates the disks having an emboss formed thereon in circular formation.

In Fig. 7 of the drawings,.still another modified form of the disk sheet is shown, wherein all. of the disks are tied or connected both longitudinally and laterally of the sheet, by tongues and in which all of the disks are of a uniform width.

ln all of the modified forms, the disks are embossed in any suitable manner, as is shown at so as to lirevent the slipping,r about or shifting of the disks, should the vulcanizing of the tire be imperfect.

rlfhc disks are also copperized, for rendering` them. susceptible lo the vulcanizing uc- 'tion of the rubber and impregnated fabric used in. the construction of the tire shoe.

In forming the armored liner, for a pneumatic tire, a sheet of impregnated fabric, indicated at 35, in Fig. 3 of the drawings, is placed upon a tablelorother support,anda sheet of rubber 35 is placed upon the upper surface of the impregnated fabric 2&5, after pochi` 's ol air to escape. after which they are again rolled or subiecteil to pressur" for forcing the air out of the indentamous formed in the disks, by embossing them, and also yfor properly positioning the various sheets in engagement with each other. -After the various sheets hare been rolled or pres ,ed together, they are vulcanized, which causes all of the sheets to adhere one tothe other, and forni the complete liner 1. The liner is inserted in the interior of the tire Q, and cemented to the inner wall 0f the shoe, as clearly shown in Fig. 1 of the drawings.

By connecting' the disks, the handling thereof, for embossing, copperizing and for properly placing themupon the opposite sides of the sheet 31 of rubber, is greatly fa'- cilitated, and the bosses on the. disks prevent their shifting or slipping, in case the vulcanizing is iniperfcct, as has been previously stated.

lhile in the foregoing, and in the drawings, only two sheets of disks have been shown, it is to be understood that any number of sheets of; disks desired may be eruploycd, and a corresponding number of sheets of rubber for forming the tire.

In placing the sheets and 33 upon the rubber sheets, the disks are disposed in overlapping positions with respect to leach other, so as to form substantially a solid sheet of metal within the tire shoe.

ln Fig. S of the drawings, a modified use of the liner is shown. In this view, an ordinary shoe for a pneumatic tire is employed, which includes a tread section l0, and a protector 41, which is placed between the outer surface of the inner casing i2 and the inner surface of the tread section 40.

The protector -ll is armored for preventing the puncturing of the inner inflatable tube, and is constructed in accordance with the manner set forth for constructing the relincjr 1.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction of the improved armor tire, and the method of assembling or constructing the armor tire will be readily apparent kto those skilled in the art to which this invention appertains and, while in theforegoing description, the principle of the operation of this invention has been described, together with various features of construction, it is to be understood that certain minor features of construction, or the method of operation, may be altered to suit practical conditions, provided such alterations are comprehended within the scope of what is claimed.
