CONSTRUCTION OF COED TIRES.
Application filed March 5, 1924'. Serial No. 697,099.
This invention relates to the construction of cord. tires, the general objectof theinvention being to stretch the fabric to a degree equal to that to which it. will be sub- 5 jected whenthe inner tube in the. completed tire is properly inflated and to permeate the fabric with rubber so that the cords: are
surrounded by rubber, thus eliminating friction, prevent stretching and renders peeling ofl of the rubber parts impossible.
Another object of. the invention is to. provide a. pair of flaps at each edge; of the fabricwhich are adapted to befolded around a. rubber strip to form the beads of the tire.
'Another object of the invention is to provide simple and effective means for stretching the fabric and forming the beads.
This invention also consists in certain other features of construction and in the combination and. arrangement of the several parts, to be hereinafter fullyklescribed, illustrated in the accompanying drawings and specifically. pointed, out in the appended claims. V
In describing my invention. in detail, refer ence will behad to the accompanying drawings wherein like characters denote like. or corresponding parts throughout the several views, and in which Figure 1 is a plan view of anapparatus constructed in accordance with this inven- 'Figure 2, is a section. on line 2-2 of Figure 4:.

Figure 11 is a section on. line 11-11 of Fi are 1. I
ignre 12 is, a section on line 155 12. of Figure. 7. i
Figure13is a fragmentary View of a por tion of the locking ring. i
In these views, 1 indicates. a supporting member which ismounted upon 'a. shaft 2. which issupported by the uprights 3. The member 1 carries-a setof hollow spokes 4E and a second set. of. hollow spokes 5,, the, second set being carried by the slides 6 whichare arranged, to slide in the member-1 and which. are provided with. arms? which have. nuts 8- thereon which engage the screw threaded. ends of the shafts, 9 rotatably mounted in the supporting member 1; and; which have pinions l0 thereon which are adapted to be engaged. by a gear 11 con 79 nected with a sliding'sleeve 12 supported by the, shaft 2 and which has a. gear 13 thereon adapted to. bemoved into mesh with a gear 1.4011 the power shaft. 1 5 by a. lever. 16. Thus the spokes 5 can be moved longi tudinally in the supporting." member when desired. The spokesfform bearings for the. shafts 17 which are provided with threaded heads. 18 on their outer ends for. engaging the threaded interiors of the hollow members 19 which are adapted to be detachably connected with the core. sections 20 and 21. As shown in F igure 12, the members 19 have their exteriors of square, shape in cross, setion, and the spokes 4 and 5 have. also square exteriors with their interiors circular to; receive the shaft 17. Beveled gears 22 are placed on the inner ends of the shafts 17 and these gears. on the. shafts in. spokes 4 are adapted to engage the teeth on one-face' of the beveled gear 23 on. the sliding sleeve 24. and the gears 22 on the, shafts in the spokes .5. are adapted to engage the teeth on one face of the. bevel gear 25 on the slid ing sleeve 26, the. sleeve 24, having av gear 27 on: its. outer end while the sleeve 26. has. a gear 28 on its outer end, these gears 27 and 2.8being arranged to be moved into'mesh with the gears 29 on the, power shaft 15. by the levers 30 and 31. I g are supported bythe parts. carried by the spokes 4; while the sections 21. are supported by the parts. carried by the spokes. 5 so that these sections 21 canbe. moved not only radially as can the. sections 20 but they can also be moved longitudinally of the supportingv member 1 and from under the sections. 20 so asto ermit these secti'ons20 to be mqved. inwarc 1 2 to their full extent, The; fi lfitins 21 are. f wedge as w Thecore. sections 20. 9 v
" to fit between the soctions and the ends of the sectionsQl have wedge-shaped pro- 'jections32' thereon for engaging recesses 33 in the ends of the sections 20 and all the sections are provided with longitudinally extending grooves 34 in one side for receiving a sectional locking ring 35 for holding curved recess formed in one of the sections Y 20 when the locking ring is given a'partial rotary movement. 7 f' locking ri'ngis held in position by'means of a screw 38 passing through an ear 39 on the sections together. I
thesections of the ring are held together V by the pins 36 andone section is. provided The abutting ends of with a curved tongue 37 for engaging a The other sect-ion of the saidsectionand'entering one of the sections 20. v The bead forming flanges 40 are connected lit ,by the brackets 41 with the interiorly screw threaded members 42 which are similar to i V the members 19. 7 These members 4-2 are engage'd' by the threaded heads of the shafts ed to'mesh with the 43 which are carried in the bearings 44 sup ported by the slides 45 in the member 1, he slides having nut parts 46 thereon which engagethe threaded portions of the shafts 47 mountedjin the member 1 and which have ".pinions 48 at theouter endswhich are adapt- I gear 49 formed with the gearjll and which is adapted to be moved into mesh with the gear 50 on the power shaft by'the lever 16. The shafts 43 have the bevel ears 51on the innerends which are designed to mesh with the teeth on the V 1 outer faces of the gears 23 and 25 when the levers .30 and 31 are moved to slide the V sleeves '24 and 26 toplace the gears 23 and 25 in mesh with the gears 51. The levers 16, 3 0 and 31 are held in their adjusted positions 7 by means of the notches 52, engagingthe keeper bar '53.
The cord fabric is provided with a pair of flaps 54 and 55 at each edge andthese flaps are foldedabout the strips 56 to form the beads of the tire and apair of rings 57 is placed on the mold to receive the inner edges of the" beads. These rings-cooperate with the bead mol'ds 40 to form the beads and after the parts have been'brought into'mold- 'ing position they are fastened together by the bolts -58so that the partially formed tire and l the. mold can be removed from the stretching v apparatus and the tireffinished in the usua1fmanner. v From the foregoingi't will be seen that by manipulating the levers 16, .30, and 31 the sections 21 ca-njbemovedinwardly and then wardly to form the beads, the locking ring 7 meshes. and when the rubber parts are built upon it it will become permeated with rub ber. The fabric iswoven several sizes sn'1all er than the'regular tire size and it is woven with a larger sized cord at the tread and reduced in size as it meets the side walls. It J is the same at both sides and its edges are provided with two flaps 101 enclosing thebead forming strips. The cord fabric is permeated with rubber before it is stretched over the mold. I
t is thought from the foregoing description that the advantages and novelfeatures of my inventionwill be readily apparent.
I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of'the appended claims.
