MACHINE FOB WRAPPING minor/rams TIRES.
[M mmals January 17, 1914. SerialNo. 812,767.
To all whom it may concern: o
Be it known that I, JAMns H. COESIR, a
citizen of the United States, residing at.
Joplin, in the county of Jasper and State 5 of Missouri, have invented. a new and useful Machine for Wrapping Pneumatic Tires, of which the following is aspecifioation. i
The device forming the subject matter of this application is a tire wrapping machine, and one object of the present invention is to provide a means whereby thewrap ping may be applied to the core, 'circumfer entially, and from the sides of the core to ward the median plane thereof.
Another object of the invention is toprovide means whereby a wrapping may be applied to a core circumferentially of the core, the wrapping consistingfo'f two parts wound about the core in opposite directions ciroumferentially of the core,
Another object of the invention is to provide means whereby the circumferential movement of the applying members may be 25 reversed. a
The invention aims to provide a novel driving mechanism for the applying.-mem+ bers and to provide a novel tension means whereby the wrapping may be controlled.
It is within the scope of the invention to improve generally and to enhance the utility of, devices of that type to which the present invention appertains. 'l
With the above and other objects in view 35 which will appear as the description proceeds, the invention resides in the combination and arrangement of partsand in the details of construction hereinafter described and claimed it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope ofwhat is claimed without departing from the spirit of the invention.
In the accompanying drawings :Figure 1 shows in side elevation, a tirevvrapping machine embodying one form of the present invention; Fig.2 is a top plan of the structure shown in Fig. 1; Fig. 3 is an end elevation of the machine; Fig. l isa fragmental section taken through one of thewrapping containers or spools; Fig. 5 is a fragmental section of the core; Fig. 6 is a detail enlarged from Fig. 2 andillust-rating thetension means andthe mechanism whereby the tension is adjusted. in carrying out the invention there is'proi Specification of Letters Patent. Patented July 1916. 1
vided-a support lvhaving, a bearing 2 in which is ,j ournaled for rotation a drive shaft 3 carrying a beveled pinion 4C. The beveled pinion 4 meshes into a beveled pinion 5 secured to the periphery of a tubular 'pri:
mary shaft 6 journaled in a bearing 7 on I the support 1. A secondary shaft 8 is journaled within the primary tubular. shaft 6 and in a bearing 9 on the support 1,.the secondary shaft 8 carrying a beveled pinion 10 which meshes into the beveled pinion 1 5 on the drive shaft The invention furtherincludes a core denoted generally by the numeral 11, the core being journaled on the end of the secondary shaft 8. Although the secondary shaft 8 is mounted to rotate i in the core 11, the core, when the machine 18 111 operation, does not rotate. The core 11, therefore, maybe described as being relatively fixed, and, when the nature of the invention is better understood it will. be appreciated that the coreneed not of 'neces-' sity be supported upon the secondary shaft 8. The core 11 is a composite structure and includes a disk-like body 12 in which the shaft 8 is immediately received, the body 12 being provided at one side with an abutment flange 14 shown best in Fig. 2, the abutment flange engaging a flange ring 15 and the body receiving the flange ring 15 and another ring 16, there being a tread 17 held between the flange rings, the flange rings being connected by screws 18 or other clamping means. The periphery of the tread portion 17 of the core is convexed as indicated at 1? for a purpose which will be set forth hereinafter.
The invention includes a pair of oppositely moving applying members, one applying member taking the form of an arm 19 held upon the primary shaft firmly but adjustably by means of a clamp bolt 20 or the like. This arm 19 is provided with an extension 21 (see Fig. 2) terminating in an angularly disposed finger 22 (see Fig.
L from which projects a tubular shaft 23. 1
Journaled on the tubular shaft 23 is a wrapping container preferably ,taking the formling the movement the wrapping as ithe same is drawn off the spool 24, this tension means preferably including a U-shaped member shown in Fig. 6 and secured to the extension 21, the U-shaped member, includ- 1 ing resilient arms 27 having seats 28 lee-- tween which the wrapping passes.
A mechanism s provided for ad usting the tension means-and with this end in view, a spring bracket 29 is secured to the extension 21 and bears upon one of the arms 27 ofthe tension device, there being a screw 30 threaded into the extension 21 and having a head which bears upon the resilient bracket 29 and constrains the same to engage one arm 27 at a varying pressure.
The" other applying member takes the formof an arm 31 held firmly but adjustengaging the side face of the spool '35; The
tension device isindic'ated at 38 and'is controlled as before by a resilient'bracket 39 and an adjusting screw 40.
Mounted upon opposite side'si of the core 11 are wrapping holders, each wrapping holder comprising a grip 41, one end of which is mounted to swing in the core, the other end of which is provided with a hook '42 which cooperates with a notch 43 in the flange of the core 11. The grip 41 is held in place by means of an angular keeper 44,
' one end of which is rotatable in the core,
the other end of which overhangs the grip.
Thewrappings may be of any form and are indicated at 45. One wrapping is wound around the spool 35 and the other wrapping is wound around the spool 24. The ends of the wrappings are engaged by the grips 41 on the core 11.
In practical operation, the wrappings 45 are wound upon the spools '35 and 24 and the spools are placed on the tubular shafts '23 and 34, the spools-being held in place by the spring tongues 25-and 36. The keepers 44 are swung to one side so as to free the D grips 41, the; ends of the wrappings 45 are engaged with 'the grips, and the grips are swung into the notches 43 to hold the ends. of the wrapping 45, and: the "keepers 44 are turned so as to overhang the rips and maintain the samein position; Vhen the drive shaft 3' is rotated, the beveled pinion 4 meshing into the beveled pinions 5 andlO will rotate the shafts 6 and 8 in opposite directions, causing the arms 19 and 21 to swing in opposite directions, whereby the wrapping containers 24 and 25 will move around the periphery of the core 11 in fop-' posite directions, circumferentially of the core. By'this operation, the wrappings 45 will be applied to thecore in two series of convolutions, each series beginning adjacent one of the flange rings 1516 and continuing'toward 'the median plane of the core,
where the two series of convolutions will meet. Owing to the fact that the tread portion 17 of the core 11 is convexed as indicated at 173 the convolutions of'the re spective'series'as they are applied to the core will be crowded laterally toward the flange'rings 15 and 16, thus disposing the wrappings in compact form about the core.
Referring to Fig. 6 itwill be obvious without detailed description that the spring arms 27 maybe adjusted to regulate the tension or drag upon the wrappings 45, thus altering the tightness with which the wraps pings are applied to the core 11.
Since the drive shaft 3 may be rotated V:
'in opposite' directions, this shaft and attendant mechanisms constitute means whereby the wrapping containers or spools 35 and 24 may be simultaneously reversed, so far as I, a the direction of their orbital movements with respect to the core 11 are concerned.
The wra m 45 1s em JlO ed to'ex-ert a b pressure on the lure during the process of manufacture, the wrapping, ordinarily, constituting no part of the finished tire. V
In Fig. 5 of thedrawings, a fragment of the tire has been shown and is indicated by the reference numeral The tire is flip. pliedtothe core, the wrapping is applied to the tire and after the tire has cured sufliciently, the wrapping is removed.
Having thus described the invention, what is claimed is 1. In a, tire wrapping machine, a core having side flanges; and means for applying a wrapping uninterruptedly to the core in oppositely wound convolutions from the side flanges of the .core toward the median plane of thecore.
2. In a tire wrapping machine, a core having side-flanges; wrapping holders on the core adjacent the flanges; and a pair of applying. members. movable circumferentially of the core; the core having a con vexed tread constituting means for crowding the successive convolutions of the wrap ping laterally and toward the flanges.
3. In a tire wrapping machine, a core having side flanges; wrapping holders on 1.
the core adjacent the flanges; a pair of applying members movable. circumferentially of the core and 'in opposite directions; means for simultaneously reversing the circumferential movement of the applying members; the core having a convexed tread constituting means for crowding the successive convolutions of the Wrapping laterally and toward the flanges.
4. In a device of the class described, a support; a tubular shaft journaled in the support; a second shaft j ournaled in the tu-' bular shaft; means for driving both shafts; a disk-like core disposed transversely of the second shaft and loose on the second shaft and of greater diameter than the second shaft; arms secured to the shafts and adapted to move in opposite directions circumferentially of the core; and Wrapping holders on the arms the Wrapping on the arms ooacting with the core to prevent a rotation of the core When the shafts are rotated. y
In testimony that I claim the foregoing as my own, I' have hereto affixed my signature in the presence of two Witnesses.
