Tire Breaker App~icator This invention relates to a tire breaker applicator and, more particularly, to a tire breaker applicator for applying breakers of a radial ply tire to a breaker building drum or to a radial ply tire carcass.
In applying breakers to a breaker building drum or to a radial ply carcass, it is necessary that the breakers be accurately positioned on the drum or carcass. Due to manufacturing conditions the breaker will have small 10 variations in width, for example, one-sixteenth to one- -eighth inch. The breaker applicator should be capable of accurately positioning the breaker on the drum and yet allow the operator to splice the ends together. Prior breaker applicators have not provided the desired accurate 15 positioning of such slightly irregular breaker fabric on the drum while allowing the operator to splice the breaker after it is on the drum.
It is an object of the invention to provide a new and improved tire breaker applicator which avoids one or more 20 of the above-mentioned disadvantages of prior breaker appli- -cators.
It is another object of the invention to provide a new and improved tire breaker applicator which accurately positions a tire breaker on a drum.
It is another object of the invention to provide a new and improved tire breaker applicator which allows the operator to cut the breaker fabric.
In accordance with the present invention, a tire 1 .~.i breaker applicator comprises means for centering a tire breaker supplied thereto comprising trays having entrance and exits ends and having lateral walls for guiding the breaker, the trays being laterally displaceable by the edges of the breaker by equal amounts from a fixed longi-tudinal center line and the trays having a smaller distance between the lateral walls thereof at the exit end than at the entrance end thereof. me applicator also includes means for extending the tire breaker centering means to the vicinity o~ a br~aker building surface and for retracting the tire breaker centerlng meanæ.
For a better understanding of the pre~ent invention, tog~ther with other and further obJects thereof, reference is made to the following description taken in connection with the accompanying drawings, and its scope will be pointed out in the appended claims.

The applicator also includes an extension spring 23 (see Figs. 6 and a) attached to one of the tray~ 12a by means of attachment to a slida~le mounting sleeve 24 attached to the tray 12a. The 1~ sleeve 24 is also attached to the rack 21. The extension spring 24 is also attached to ~ne of the laterally fixed guide means 19 for positioning the tray 12a against one of the edges of the breaker for centering the breaker. me tray 12b is attached to a slidable sleeve 52 which is also attached to the rack 20.
Referring to Figs. 1, 4 and 6 of the drawings, the applicator includes means for extending the tire breaker centerlng means 11 to thc vicinity of a breaker building sur-face and for retracting the tire breaker centering means 11.
me means forextendingand retracting the breaker centering means comprises a cyli~der 30 having a displaceable piston rod 31 attached by member 32 (see Fig. 4) to longitudlnally dis-placeable guide rods 18, 19 supporting the centering means llo The applicator includes a pair of centerlng means for centering a pair of tire breakers and a pair of means for ex-tanding and retracting the pair of centering means. The second centering means lla is fiimilar to the first centering means 11 and the second means 18a, l9a, 30a~ 31a, 32a for extending and retracting the second centering means is similar to the first means for extending and retracting the f~rst c~ntering means.
As represented in Figo 3, the pair of means ~or ex-

5 -tending and retracting the pair of centering means sequentially extend the pair of centering means to substantially the same point ad~acent the breaker build-ing surface 33. The centering means pre~erably extend to within three inches o~ the surface 33 of the breaker building drum.
Referring to Fig. 1, a drive roller 34 driveæ
breaker fabric 35 to the centering means ll over platform rollers 36 and feed rollers 37. A second breaker fabric 35a is driven by roller 34a over platform rollers 36a and feed rollers 37a to the centering means lla. As represented in Fig. 2, the centering means 11 is extended by displacement of the piston rod 31. As represented ln Fig. 3, the centering means lla i5 extended to substantially the same point as the extended position of the centering meanR 11, represented in broken line construction, while the centering means 11 is in lts retracted position represented in solid line construction.
Referring now to Figs. 4 and 5, there i9 represented means for alternately locking and releasing the piston rods 31 and 31a. A grooved clamp 40~ represented in section in Fig. 1, mounted on a slidable rod 41 actuated by cylinder 42, is represented in ~ig~ 4 ln a release position. A slidable rod 43 actuated by the cylinder 42 supports a grooved clamp 44, represented in section in Fig. 1 and represented in a lock position in Fig. 4. me clamp 40 in releas~ position allows nut 45 on plston rod 31 to move freely, allowing the piston rod 31 to extend in response to air pressure. At the same t~me, the nut 45a is clamped to the nut 46a (Fig.l) on the cylinder 30a, locking the piston rod 31a ln retracted posltion.
.
As represented in Fig. 5, with the cylinder 42 in its alternate operating position, the clamp 40 clamps the nut 45 on piston rod 31 to the nut 46 on cy-linder 30 (Fig. 1), locking the piston rod 31 in re-tracted position. me clamp 44 in release position allows nut 45a on piston rod 31a to move freely, allowing the piston rod 31 to extend in response to air pressure. A
conventional limit switch 49 is actuated by clamp 44.
Referring now to Figs. 6, 7, 8, and 9 when the centering means 11 i8 extended and the fabric 35 passes through the entrance end of the centering means 11 to the exit end, the longitudinal edges of the fabric 35 press against the lateral walls 15, 16 of the trays 12a, 12b separating the trays by equ~l amounts from the loneitudinal center line 17 due to the operatio~ of the racks 20, 21, pinlon 22 and spring 23, and thereby centering the breaker fabric. It will be understood that the sleeves 51, 52 are slidable on suitable bearings 55 on support rods 53, 54 between rods 18, 19. Due to the tapering of the trays 12a, 12b, if the breaker fabric 35 is of uniform width, the breaker fabric will be under greater compression at the exit end of the trays, which provide accurate centerlng and positionlng. If the breaker fabrlc has a sllghtly wider edge irregularity, due to the wlder entrance end of the trays, the fabric can enter the trays and become slightly compressed during passage through the trays which will provide accurate centering ~nd positioning. mus, the tapering of the trays allows the applicato~to accept a slightly lrregular breaker fabric.
After the breaker fabric is applied to the drwm with 33~
the assistance of an operator,the operator may then cut the fabric with a knife across the tray through slots provided in the lateral walls 15 and 16 (See Fig. ll)and 1hen the applicator may be retracted. This method will prevent the now loose end of the breaker to fall on to the starting end below in an irregular fashion.
It should be understood that a minimum width fabric is represented in Fig. 8 and that this fabric is sufficiently wide to cause a slight spacing between sleeve segments 51, 52 to allow centering of the fabric to be accomplished. Referring to Figs. 10 and 11, a maximum width fabric is represented and this fabric is sufficiently narrow to cause a slight spacing between sleeve segments 51, 52 and the members attached to rods 18, 19 to allow centering to be accomplished. Ordinarily, a breaker fabric of intermediate width is utilized.
While there has been described what is at present believed to be the preferred embodiment of this invention, it will be obvious to those skilled in the art that various changes and modifications may be made therein without de-parting from the invention, and it is, therefore, aimed to cover all such changes and modifications as fall within the true spirit and scope of the invention.
Referring to Fig. 1, a drive roller 34 driveæ
breaker fabric 35 to the centering means ll over platform rollers 36 and feed rollers 37. A second breaker fabric 35a is driven by roller 34a over platform rollers 36a and feed rollers 37a to the centering means lla. As represented in Fig. 2, the centering means 11 is extended by displacement of the piston rod 31. As represented ln Fig. 3, the centering means lla i5 extended to substantially the same point as the extended position of the centering meanR 11, represented in broken line construction, while the centering means 11 is in lts retracted position represented in solid line construction.
Referring now to Figs. 4 and 5, there i9 represented means for alternately locking and releasing the piston rods 31 and 31a. A grooved clamp 40~ represented in section in Fig. 1, mounted on a slidable rod 41 actuated by cylinder 42, is represented in ~ig~ 4 ln a release position. A slidable rod 43 actuated by the cylinder 42 supports a grooved clamp 44, represented in section in Fig. 1 and represented in a lock position in Fig. 4. me clamp 40 in releas~ position allows nut 45 on plston rod 31 to move freely, allowing the piston rod 31 to extend in response to air pressure. At the same t~me, the nut 45a is clamped to the nut 46a (Fig.l) on the cylinder 30a, locking the piston rod 31a ln retracted posltion.
.
As represented in Fig. 5, with the cylinder 42 in its alternate operating position, the clamp 40 clamps the nut 45 on piston rod 31 to the nut 46 on cy-linder 30 (Fig. 1), locking the piston rod 31 in re-tracted position. me clamp 44 in release position allows nut 45a on piston rod 31a to move freely, allowing the piston rod 31 to extend in response to air pressure. A
conventional limit switch 49 is actuated by clamp 44.
Referring now to Figs. 6, 7, 8, and 9 when the centering means 11 i8 extended and the fabric 35 passes through the entrance end of the centering means 11 to the exit end, the longitudinal edges of the fabric 35 press against the lateral walls 15, 16 of the trays 12a, 12b separating the trays by equ~l amounts from the loneitudinal center line 17 due to the operatio~ of the racks 20, 21, pinlon 22 and spring 23, and thereby centering the breaker fabric. It will be understood that the sleeves 51, 52 are slidable on suitable bearings 55 on support rods 53, 54 between rods 18, 19. Due to the tapering of the trays 12a, 12b, if the breaker fabric 35 is of uniform width, the breaker fabric will be under greater compression at the exit end of the trays, which provide accurate centerlng and positionlng. If the breaker fabrlc has a sllghtly wider edge irregularity, due to the wlder entrance end of the trays, the fabric can enter the trays and become slightly compressed during passage through the trays which will provide accurate centering ~nd positioning. mus, the tapering of the trays allows the applicato~to accept a slightly lrregular breaker fabric.
After the breaker fabric is applied to the drwm with 33~
the assistance of an operator,the operator may then cut the fabric with a knife across the tray through slots provided in the lateral walls 15 and 16 (See Fig. ll)and 1hen the applicator may be retracted. This method will prevent the now loose end of the breaker to fall on to the starting end below in an irregular fashion.
It should be understood that a minimum width fabric is represented in Fig. 8 and that this fabric is sufficiently wide to cause a slight spacing between sleeve segments 51, 52 to allow centering of the fabric to be accomplished. Referring to Figs. 10 and 11, a maximum width fabric is represented and this fabric is sufficiently narrow to cause a slight spacing between sleeve segments 51, 52 and the members attached to rods 18, 19 to allow centering to be accomplished. Ordinarily, a breaker fabric of intermediate width is utilized.
While there has been described what is at present believed to be the preferred embodiment of this invention, it will be obvious to those skilled in the art that various changes and modifications may be made therein without de-parting from the invention, and it is, therefore, aimed to cover all such changes and modifications as fall within the true spirit and scope of the invention.
