.To all wiz/om it may concern:
Be 1tu known that I, CLARK FRANCIS bien, a citlzen of the United States, residing' at .I Trenton, in the oountyl ot Mercer and State .dodeclare the 'following' to be atfull,
oi? New Jersey, have invented certain new and useful improvements in Tire-Tubes and Methods 4ot Constructingthe Same and .l clear, ,and exact description of the invention, such as will enable others skilled in the art to which .it appertains to makeandl use the i Sam.
the Iinner tubes of automobile and other l5 My invent'on'relates to improvements in tires, and .has-:tor its object to provide a heavily reinforced tube and a novel method` I of constructing the same.
' plete state, but deflated..
'views showing two moditlccl forms Fig. l is a sectional perspective showing' i the condition of the tube when inflated;
Figs. S and 9 are sectional perspective oi corrstruction;
Fig. 1() is a similar view illustrating the manner in which the .fabric vreinforcements may be located on the exterior ot' the tube rather than on the interior thereo'i and Figs. 11, lil and 13 are sectional perspectives showing still. other modifications.
.ln the manufacture of the improved tube,
` kan uncured tube l is placed upon a-mandrel tubo, between the tread and of 'the vWell known type and non-vulcaniaw able material 2 is applied to the sides ot said rim portions thereof. This material may be in strip form as Shown in the draw in the form of a powder c1- fiuid. A band 3 of processed fabric or more than one band it desired, is now applied to the rim portion of the tube 1, with its edges 5 overlapping the.nonvulcanizable material 2 as shown in "Fig This having been done, additional non-vulcanizable material applied to the fabric band 3 as illustratedy 1n Fig. 3, and a ings or it might Well be second processed fabric band 7 or more than one band it required, is then applied to the tread portion 8 of the tube, with its edges 9 overlapping the material 6 and substantially meeting each other as indicated in Fig. Il.
The structure so far described, is placed in a mold and suitably cured, after which the noinvulcauieable material y2 and (i is removed, the result being that the bands 3 and l' are secured to the tube 1 substantially throughout their widths, whereas their edges remain unsecured and overlap each other in the toi-ins ci flaps. The structure now rcmoved from the mandrel and if the rein-y forcing bands are to remain on the exterior of the tube l as shown .in Fig. l0, the ends of said tube are spliced together to complete the article. It, however, the bands in question are to be located on the interior of the tube, as irs-preferable, the structure will be stripped or turned so that the inner side becomes the outer side, before the ends of the tube are joined.
.litter completion, the tube assumes the comlition illustrated in Fig. li, and when' in tlatcd, it will be observed that the tivo sets oi flaps overlap only to a suiicient extent to protect the highly elastic sides 10 of the tube, to which sides said flaps are entirely unse" cured (sec liig. 7).
.its illustrated n Fig. 8, the flaps or edges of the tread lgiand 'i' may be joined by a web ll ci rubber or any other preferred yielding material. in the iigure 'in question, the web is shown of solid construction, Whereas Fig. 9' illustrates a somewhat 'similar web 12 having,- openings i3 so that narrow straps lll are formed between said openings to connect the flaps.
All fabric is out obliqii-ely of the Weave so that both bands 3 and 7' may yield a suitable amount `with the tube i, when the device is inflated. rlhc larger proportion of the olaf'- ticity otI the device, however, lies in the sides 10 which are free of' connection with .the fab- Iric bands. liilm'erthelcss, those sides are efy fectivtely protected and reinforccd by the overlappingl flaps.A is will be clear from my former Patent 1,135,273 of April 1b, 1915, proper cutting and application of the fabric will cause the necessary rim side contraction. and tread side expansion when inliating. This expansion and contraction is necessary since the tube is made straight and then toi-med into a ring which must adapt itseli to the casing wit-hout rinhling or creasing, thus requiring the smaller rim side diameter' caused by said rim side expansion, and the large tread side diameter allowed by the tread side expansion.
The expansion and contraction above referred to may be obtained in several ways.
First, by applying the tread fabric cut at @t5 degrees bias, it will expand under infiation. When applying the rim side fabric vif it is cut at et degress and stretched to S0 degrees or 90 degrees, it under inflation.
Second, if I cut the tread side fabric #l5 degrees bias and the rim side S0 degrees or 90 degrees bias, the tread side will expand and the rim side contract under inflation, without the necessity of stretching the rim side fabric When applying.
Third, to econornize in time and labor, if I calender the fabric with friction under tension, I stretch the fabric thedesired amount and Without extra Work.
Also, if after building the tube up on a straight mandrel, I cure it on a circular mandrel. it Will be shaped to fit the shoe or will contract casing.
In Figs. 1l, l2 and 13, I have illustrated slightly different forins Iof the invention. Fig. l1 shows the fabric 't'a on the tread side only of tube l; Fig. 12 illustrates fabric 3 on the rim side only, and Fig. l shows fabric 7* and 8b respectively, on the tread and rim sides. The edges of the fabric in each case are left free from the tube and in Fig. 13 these edges do not overlap as in Figs. 6, 7, 8, i) and l0. It is understood that the fabric in all cases will be properly cut and applied to meet the occasion.
From the foregoing, taken in connection with the accompanying drawings, it will be obvious that although the method of constructing the artieleis simple, it will produce highly effective results. Similarly, the tube may be constructed With ease and at little expense, yet its life and efficiency will be greatly prolonged by its novel construetion. The drawings illustrate the preferred forms of my invention, but I wish it understo od that Within the scope of the latter, as clanned, numerous minor changes might Well be made.
I claim:
l. The method of constructing .an inner tube for vehicles comprising the steps of applying non-vulcanizable material to the sides of an uneured tube, between the rim and tread portions thereof, applying a band of fabric to one of said portions with its edges overlying,- said non-vulcanizable inaterial, applying` additional non-vulcanizable material to the outer side of said fabric band, applying a second fabric band to the portion of the tube opposite the first named band with its edges overlapping said additional non\'ulcanizable material, and curing the entire structure.
2. The method of constructing an inner tube for rehicles comprising the steps of applying non-vulcanizable material to the sides of au uncured tube. between the rim and tread portions thereof, applying a band of fabric to one of said portions with its edges ovcrlapl'iing,- said non-vulcanizable material, and curing the entire structure.
3. A rubber inner tube having a fabric band cured on its wall and extending over approximately half the cross sectional cir cumference of the tube with its edges left free to form iiaps.
4. The combination with an inner tube for tires, of two bands of fabric secured on the tread and rim portions of said tube respectively, the edges of said bands being free of connection to the sides of the tube to render said sides highly elastic, said edges overlapping te protect said elastic sides, the edges ef one band being 'unsecured to those of the other.
5. .er structure as specific in claim Li together with yieidinp` means connecting the edges of one of said bands.
6. A rubber inner tube having a fabric band cured on its inner side and extending over approximately half the cross sectional circumference of the tube with its edges left free to form iaps.
In testimony whereof I have hereunto set my hand in the vpresence of two subscribing witnesses.
