UNITED STATES PATENT orr cn.
JUAN rumcnr Y MARTI, or unease, seam.
To all whom it may concern.
Be it known that I, JUAN Mnncnr, 1' Mann, a subject of the King of Spain, residing at Tarresa, Spain, have invented certain new and useful Improvements in Woven Wrappers for Tires; and I do hereby dcclarethe following to be a full, clear, and exact description ofthe' invention, such as will enable others skilled in the art to which it appcrtains to make and use the The wheels of bicycles, fllllOlllQbllt-BS and other vehicles are usually provided with pneumatic tires-having an air chamber more or less well protected by covers of rubber alone or of rubber combined with sheets of cotton cloth, or by wrappers of cloth cut from the piece and formed in the shapc which corresponds to the section of the tire,
and having numerous corrugations at both sides. In other vehiclesvthere are also employed rubber tires very often without a protecting ring or wrapper at all, or tires of solid rubber which are covered with wrappers of cotton cloth or other material. ln'all these cases, when the wrappers are heated due to speeding, the several cloths -soon become disjointed 01' separated from each other and finally so worn that the wra )per is quickly destroyed.
The new or improved tirewrap ers which constitute. the object of this ap; liention, consist in circular wrappers or rings so made of cloth while in the loom that the havea circular form and shape corresponc ing to the section of the tire over which they lit; and therefore in completing them it is only necessary to join the ends and to insert the wires or the ribbons which. form the heels. p
On the drawing annexed to this specification is represented a section of a reinforced cloth tire covcrwoven into a sin le piece of fabric, showing on an enlarged scale the warp and woof threads.
The section of the wrapper may be considered as divided in )ortions or zones; a central zone a and two ateral zones 1) and c,
it being necessary, when weaving the cover that the central zone a be woven with a circumference having a lesser diameter than the lateral zones 1;, c, as only in this way it is possible that the finished wrappers take a U shape and a circular form corresponding tothe tire, withoutforming wrinkles or corrugations. To this'end, the Warp threads Specification of Letters Patent. Patented Doc. 14, 1909. Application filed September 4, 1907. Serial No. 391,749. I
, 0, m, n, are disposed on independent boloms or spools, each of them having a brake. Thereby it is possible to impart a different length or development to all of the threads comb tightens the weft threads Q, r, s, t, andthen it closes again when the comb moves backward; while the cloth is held in place till the comb moves forward again. The
mouth of these pineers is proportional in shape to the section of the woven cloth; if the latter is of uniform thickness, the pincers are to be straight, but if it is thicker at the middle than at the sides, the pincere mouth is to be greater at the center than at the sides. The cloth on issuin from said pincers has the pro or shape of the tire, as the threads have a different tension and produce a greater amount of cloth at the center than at the sides. Owing to the proper proportionality of these elements, it is possible to give to the central portion of the wrapper the development properly corresponding to the reater circumference of the tire; and the ateral. parts have also the development corresponding to the circumferences progressively decreasing in diameter.
After weaving, the wrapper is cut to the length which corresponds to the diameter of the tire and the ends are joined together either by sewing them or interlacing them so that the cloth be tapered, as aforesaid. Finally, wires are secured to the edges, either by sewing, or by folding the edges.
The wrapnbr may be woven of the same thickness throughout its whole section, or it may be thicker at its central zone, that is to say, at the part which is in contact with the ground, in order to give to this zone a greater. resistance and consequently to 111- crease the durability of the wrapper as shown in the drawing. I
The increased thickness of the central zone of thewrapper is obtained by insertin through the corresponding central part 0 the comb a greater number of threads namely one, two, three, four or more threads, according to the thickness that the wrapper must have"; and through the lateral parts of the comb corresponding to the lateral zones of the Wrapper, a smaller number of threads or even a single thread is inserted.
In this way itis possible to cause the thickness to progressively decrease from the middle to the sides,-as shown.
. For Weaving the wrapper, I employ that number of weft threads u, o, and of warp threads is, Z, which may be found necessary to produce the desired thickness of the wrapper and to produce the reinforced part a.
The several cloths are interwoven to each other as above except at the parts near the edges, where the cloths g, and h, are separated from each other. The inner cloth 9 is represented somewhat longer than the outer one it, but it is obvious that cloth g could be shorter than the cloth it without any feature being altered. Thus it vwill be seen by the manufacture of a tire ofthe character described, that when the central part wears through one cloth (the outer one for example) there will be still beneath it other remaining cloths forming a very compact and resistant fabric.
, Havingthus described my invention and in What manner the same is to be performed, I declare that what I claim as new and de- SII'G to secure by Letters Patent, is
1. A substantially U shaped tire cover of a v continuous Woven fabric, having a woven reinforcing ply overlying the tread portion of the cover and thereby thickening the same, and having cloths g and h at one eX- tremity of the cover, substantially as described.
ing' a greater amount of cloth at the center,
or tread portion, than at the sides, and provided at one of its edges with means for securing said cover to the tire, consisting of woven cloths one of which is longer thanthe other, substantially as described.
, l. A substantially U shaped tire cover composed of a continuous woven fabric having a plurality of Woven reinforcing plies overlying the tread portion, and fastening means at its edges, consisting of a plurality of woven cloths two of. which are longer than the others, substantially as described.
In testimony whereof, I afiix my signature, in presence of two Witnesses.
