To all er1/wm t may concern.'

Be it known that I, FRANK Fnnron, a citizen of the nUnited States, and resident of Akron, Ohio, have invented certain new `and useful Improvements in inner Tubes for Pneumatic Tires, of which the follow.

tieularly for use in connection with motorva simple and effective means by which the overlapping ends may be readily connected and disconnected and which means will be located wholly between the juxtaposed faces of said ends leaving the exterior of Athe tube entirely free from any projection,

as it has been found in practice that any fastening vmeans which offers a projection or ridge, and especially ifvsuch projection be of a hard and non-yieldingcharacter,

produces a detrimental effect on the tire similar to a wrinkle or fold in the fabric.

The invention includes the novel arrangement and features of construction hereinafter described and particularly de fined by the `appendI d claims, an embodiment of the invention being illustrated in the accomlmnying drawing, in which,

Figure l is a side elevation of a tube einbodying my invention, the same bcinrshown inflated but with the ends detached Fig. 2 is a similar' view showing the ends ijverlapped and connected. Fig. 3 is a perspective detail showing the overlapping ends as they appear when deflated and in rendiness to be connected.

Referring by reference characters to these 'vulcanized to the tube.

drawings the letter A designates the usuall preferably form the divided portion atv a point remote or spaced from the valve stem and these divided or separated ends are flattened or closed in a suitable manner as by vulcanizing the opposing walls together for a portion of their length, as indicated at' C, these ends are brought together and overlapped after the tube has been placed within the outer case or shoe, and in order to hold them together without producing any bulge, ridge or projection upon the cuter surface and without interfering with the resiliency of the tire at the point of overlap, 'l provide fastening` means located wholly between the overlapping portions.

in the forni shown inv the drawings such fastening means take the form of detach-- able fasteners 'of the ball and socket or Srlfwe fastener type, as indicated at B3, ln ci to secure these fasteners vin' position l preferalily first secure them to strips of fibrous material, indicated at B, which fibrous strips are afterward cemented or llfhen the ends are to be connected, it is only necessary to place one end into overlapping position upon the other end with the'respective fasteners in alineincnt and snu p them together and when thus eoniiected, it will be seen, us shown in Fig. 2, that the tube is free from any external projection which would have va detrimental effect upon the easing.

Havingr thus described my invention what lclaim is:

l. An inner tube for inflatable tires having end portions with the walls vulcanized together to form fiat closed ends, said flattened ends overlapping each other and having smooth continuous exterior surfaces, and separable fasteners, the parts of which are carried respectively wholly by theljugtaposed faces of said overlapping' portions.-

2. An inner tube for inflatable tires having end portions with the walls vulcanized togethey," to form fia-; olosec ends, said ends overappmg @zich oth@ with the dosed pari', o oooh and extendmg beyond and overlying the natabe part of the adjoining and Wtnesses operating part secured to the na'table por cion of the tubo. 10-
