ARMOR-RELINER FOR TIRES.

Specification of Letters Patent.

Application filed April 14, 1920. Serial No. 373,895.

To (ZZZ whom it may concern.

Be it known that we, SEYMOUR A. Rouse and Hans C. S'roonEL, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain n w and useful Improvements in jrrmor-ltelinersfor Tires; and we 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 w iich it appertains to make and use the same.

This invention relates to new and useful improvements in armor reliners for tires of the character described, illustrated, and claimed in U. S. Letters Patent all-1,227,673 and has for one of its objects the provision of means for preventing the connecting tongues of the disks from becoming separated or detached from the disks when broken, thereby obviating the danger ofthe tongues working through the inner liner and puncturing the inner tube. V

Another object of this invention is the provision of disks arranged in spaced parallel rowsand one row of disks are 0011- nected longitudinally of the device and the other disks connected transversely to each other and connected laterally to the first named row of disks so as to make the second named disks very pliable laterally and will TGlllllil them to be straightened laterally if they are not straight when punched or made from a sheet of metal. with uneven edges:

further obiect of this invention is the provision of di. they assembled in an inner liner, each disk i be supported at its center as well a its corners by the disks thereunder, so as to obviate bending ofthe disks first in one direction and. then in the otl ieii', during the use of the device, which has proven disadvantageous owing to the fact that the disks when unsupported at their centers will soon become broken owing to the metal becoming crystallized from the constant bending back and forth of the disks at their centers.

A still further object of. thisin'vention is the provision of an armor reliner for tires of the above statedcharacter,*which shall be simple, durable and eilicient, and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain ts of such shape that when.

novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of our invention, reference is to be had to the follow- 1 g description and accompanying drawings, in which- Figure 1 is a transverse sectional view illustrating a tire with an armor reliner within the same and overlying the inner tube and constructed in accordance with our invention,

Fig. 2 is a fragmentary plan viewillustrating one of the armor plates or members and the manner of connecting the various disks together, 1

Fig. 3 is a similar view illustrating a pair of armor members or plates arranged one over the other and showing how the outer rows of disks can have lateral movement in relation to the center or main row of disks,

Fig. l is a detail View drawn on an en larged scale, illustrating the specific construction of the tongues for connecting the disks together,

Fig. 5 is a fragmentary plan View, illustrating another form ofarmor member or plate,

Fig. 6 is a similar view illustrating a pair of said armor members 01' plates arranged one over the other.

Referring in detail to the drawing, the numeral 1 indicates a tire or shoe of ordinary construction which has arranged therein the inner tube 2 that. is inflated to support the shoe 1. The invention which is an improvement over the patent heretofore referred to is arranged between the inner tube and the shoe for the purpose of preventing the inner tube from being punctured and also obviating blow-outs of said shoe. The inner liner 3' consists of pliesof uncured rubber impregnated cotton fabric 2 which are placed one on the other and stretched over a core so asto fit. an inflated tube. A pair of'armor members or plates 3 are covered with layers of rubber 4:" and also a layerof rubber 5 is placed between the plates 3' and said plates and layers of rubher are positioned on the lies of fabric 2 and covered by a layer of fabric .6 and then subjected by a vulcanizing process to cause the layers or plies of fabric and rubber to adhere to each other about the armor constructed from steel or similar material andeach consists of a plurality of substantially rectangular or square disks l arranged in parallel rows. Themain rows of disks are connected together longitudinally by tongues 6, while the other rows of disks are connected transversely by tongues 7 and also connected laterally to the main rows '5 of the disks bytongues 8, so that'the outer rows of disks are free to have lateral movement in relation toeach other and in relation tothe main row, which will permit said rows of disks to'adjust themselves to a straight edge. This is very essential in that it is almost impossible to secure sheet steel cut with straight edges and the disks being of square or rectangular shape, also will when asseme bled more readily form a straight edge which is not as readily obtainable by circular or oval disks as in the patentreferred to.

The tongues each decrease in width'to- V ward their centers so as to make the weakest points of thetongues at their medial por tions and in casethey break during the use of the device,,the' ends of the tongues'will remain integral with the disks, thereby obviating any danger of loose or small particles of steel within the inner liner which would'be very disadvantageous in that the small particles of steel would be liable to puncture the inner tube 2. p j

When arranging the armor plates or members one above the other, the main row .of disks 5 which are connected longitudinally are arranged an even distance upon each side of the center of the' tread of a tire and the disks'of the outer armorplateor member closes the spaces between the disks of the inner armor plate or member.- When the plates or members are "so assembled or arranged in relation to each other, the upper rectangular or square disks rest upon the inner disks of the inner armor plate or memher and are supported at their centers as well as at their corners by said disks so as to prevent the disks from being bent first in one direction and then in the other which would cause said disks to become broken owing tothe steel becoming crystali-zed by' such movement. p

By'having the disks rectangularor square givesthem agreater bearing surface on each other than itis possible to obtain with other shapes of disks, and avoids the weakness caused by punching so much of the, material are not sufficiently supported.

Such slight overlapping causes these edges frequently to break off forming loose particles that do much more harm to the rubber and covering than larger pieces when broken, besides too much of the centers of therdisks Referring to Figs. 5 and 6' which illustratev another form of our invention, the disks 9 are arranged in diagonal, andparallel rows and the disksof each row are connectedby tongues 10 similar in construction to the tongues of our other form of invention. The diagonal rows of disks are. connected bytongues 11 to form armor plates or members which are placed one over the other. The disks 9 are rectangular in shape and when'the armor plates or members constructed from said disks are placed one over the other, the corners of the disks are supported by-the disks thereunder and also the spaces between said disks are closed.

VVhilewe-haVe shown and described the preferred embodiment of our invention, it

will be understood that minor changes in construction, combination, and arrangement of parts maybe made without departing from the spirit and scope of the invention as claimed. 7 I 7 Having thus described our invention, what we claim is z.-

1. Annrmor for tires comprising a pad, plates embedded in said pad and each ineluding rows of square disks, tongues connecting some of said disks longitudinally, tongues connecting other of said disks transversely, said tongues having their medial portions reduced ,in width so that when broken they will breakattheir medial portions andQremain attached to the disks.

2. An armor for tires comprising a pad,

plates embedded in said pad and each in clud ng rows of square disks, tongues connecting the disks of each'row, and tongues connecting some of the disks of one row to the disks of the adjacent ,rows, said tongues having their medial portions reduced.

In testimony whereof we afiix our signa- BoB'r. W. Weren't, MYRTLEPATTE neon.
