To all when: it may concern:

Be it known thatiI, WILLIAM C. Srnvnns, a citizen of the United States, and a resident of the city of Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Wrapping-Machines; and I do hereby decl are that the following is a full, clear, and exact deseri tion of the same, reference being had to t 1e accompanying drawin s, and to the numbers of reference marked t ereon, which form' a part of this specification.

This invention relates more particularliy to a machine for spirally wrapping or wm ing a covering strip, such as paper, about annular bodies, for example, automobile tires, and coded wire and the like, or,of course, to afford a spirally wound wrapping about polished pipe, rods, or any other object capable of receiving such a wrapping. lcretofore, practically all, or a large part of such wrapping, has been done by hand, and, in conse name, the expense for such wrapping has won unnecessarily la rge,-a nd the wrappings have not been applied with such uniformity as to present a pleasing appearance, nor sniliciently well so that the wrapping would remain long in place. Those articles so wrapped, have soon become exposed by the slipping of the wrapping material, thus presenting a very unsightly appian'anw, and, what is more serious, permitting injury to the contents of the packil e.

'lhc object'of this invention is to afford a wrapping machine adapted for operation at hi h speed, to wrap annular objects with en )Stllllllilli uniformity, and to ap ly a continuous s irally wound covering t iereon.

It is a so an object of the invention to afford an exceedingly simple and compact device for the purpose specified, having a large range of adjustment, to adapt the machine for wrap )ing annular bodies of different sizes, and in which the utmost facility for the insertion of the bodyto be wrapped, and the removal of the same from themachine after the wrapping, is attained.

it is also an object of the invention to provide means for positively supporting, and for rotating the body to be wrapped, and for adjusting said supporting and rotating means relatively to each other and the wrapping mechanism.

It IS an object of the invention also to afford an annular shuttle, having a reel of wrapping material mounted thereon, and

' means for rotating said shuttle through the eye of the annular body to be wrapped,

while simultaneously rotating said annular body.

he invention embraces other important objects, as more fully hereinafter set forth. lhe invention (in a preferred form) is illustrated in the drawings, and hereinafter more fully'deseribed.

In the drawings: Figure 1 is a side elevation pf a device embed ing my invention, showing the annular bad y to be wrapped, in dotted lines. Fig. 2 is a central, transverse section thereof, with parts in elevation. Fig. 3 is an enlarged, sectional view, taken on line 3-3 of ig. 2, and with the belt pulleys shown in elevation. Fi 4 is an enlarged face view of the annu ar shuttle and i216 mechanisms carried thereon. Fig. 5 is an edge view of the same. Fi 6 is a section on-line- 6-6 of Fi 4. lg. 7 is a fragmentary detail, part y in section, of a part of the. shuttle. Fig. 8 is an elevation of shuttle locking means. Fig. 9 is a delivery QItLGlBVittiOIl-Of the folding nozzle. Fig. 10 is--"' front face view thereof. Fig. 11 is an enlarged face'view of the reel carrier. Fig. 12 is an enlarged, sectional view of the front adjustable guide pulley. Fig. 13 is a sectional view, with parts 1n elevation, of the upper or rear gui e and driving pulley for the shuttle.

As shown in the drawings: 1, indicates a relatively low base or table, supported upon a suitable frame or legs 2, and having a central longitudinal slot therethrough. Journaled transversely of said table on the top thereof, is a driving shaft 3, having at the outer end thereof, a tight and a loose belt 7 is rigidly b0 ted to said table with the arms of the crescent directed upwardly and outwardly, or forwardly, as shown in Fig. 1.

Ri idly secured on said shaft 3, is a belt pu ley 7 having a peripheral flange 8, pro- ]ectin circumferentially on each face thereof, ,a 'ording a grooved )eriphery for the belt 9. Journaled longitudinally of the table on each side of sald belt pulley 7, in

, bearings 10 and 11, are shafts 12 and 13,

trained a sprocket chain 20, which also is trained about a sprocket wheel 21, journaled on the shaft 12, and integrally, or otherwise rigidly connected with the worm gear 22,

:also rotatably journalcd on said shaft and in mesh with a worm 23, on the shaft 3, so

that the rotation of said shaft 3, by means of its tight belt pulley, acts through the medium of said Worm and worm gear and sprocket wheels and chain, to rotate the rooved feed or advancing rollers 18. lileans are provided for adjusting said feed or advmuring rolls relatively to cachother. For this purpose, as shown, a downwardly directed arm 24, is provided on each of said sleeves 14, and carried on the lower end of each is a nut 25, through which extends a screw shaft 26, pivotally mounted in a s'uitable bearing 27, therefor, secured upon the table 1, rotation of one of said screw shafts acting on the nut 25, to swing the correspending advancing or feed roll outwardly or inwardly, dependent upon the direction of rotation, thus enabling either or both of said advancin and feed rolls to be adjusted to the most efficient position for supporting and rotating or advancing the object to be wrapped. Outward adjustment of said feed rolls obviously permits the supported object to be supported somewhat lower in the machine, while inward adjustment of the feed rolls supports said articles higher in the machine. Rotation of the shafts l2 and 13, because of the ecentric mounting thereof,

serves also to vary the tension on the corresponding'sprocket chain 20. Mounted on said rooved driving pulley 7, with its flat periphery fitting i the groove in the periphery of said iving pulley, is the annular shuttle 28, which is thus mounted transverselv of the tire or other body to be wrapped.

Extending through the forward arm of the crescent frame 6, at its extremity, is a shaft'29, provided on the inner side of the frame with a collar 30, to bear against the face of the frame and at its outer end provided with a nut 31, or-other means for rigidly securing the same from movement in the frame. Eccentrically connected with said shaft 29, at its inner end, or that 0p 0- sitethe nut 31, is a wrist pin 32, on which is journaled a peripherally flanged pulley 33, which may be constructed in any suitable manner, or, as shown in Fig. 12, laid up in part of sections of friction pa r or other suitable material 34. Said fl iiilged alley is held in place on the wrist pin 32, iy means of suitable nuts or other releasable means 35. The other or rear arm of said crescent frame 6, at its extremity, is longitudinally slotted as shown in Fi 13, and extending through the slot is a ho t 36,

provided with a head 37, which bears against one side of said arm, while suitable nuts 38, as shown in Fig; 13, engage the other side thereof to clamp said bolt rigidly in adjusted position. A stud shaft 39, in-

tegral with said bolt, projects outwardly from the head thereof, and journaled on said stud shaft is a, grooved belt pulley 40. Said grooved; pulleys 31 and 40, receive the periphery of the annular shuttle 28, in the grooved facesv thereof, while said shuttle is supported on the grooved driving pulley 7, thus engagin said shuttle at three points,

at substantially equal distances apart, and

permitting the shuttle to rotate freely therewith and therebetween. A belt 9, trained ,about the grooved driving pulley 7, and the grooved pulley t0, also engages the periphery of the shuttle-28, for the entire distance between thepulley 7, and said pulley 40, thereby acting to rotate said shuttle. V A hinged section 41, is provided in said shuttle to permit the opening thereof for the insertion or removal of the article to'be wrapped. As shown, said hinged section is pivotally engaged at one end on the end of the shuttle member 28, by means of a pin 42, and at the other end is provided with a. projection 43 on both sides theerof, adapted to receive the web 44, of the shuttle therebetween. A pin 45, extends transversely v through said projections, and is adapted to seat in aninclined'notch 46,115 shown in Figs. 4, 6, and 7, in the other end of said shuttle member, thus-insuring a. true periphcryfor the shuttle under all conditions when the hinged section is closed, as shown in Figs. 4 and ,7. Means are provided for locking said hinged section in closed position. For this purpose, as shown, a notch in the shuttle 28, indicated at X,'in Fig. 7. is provided at the inner periphery thereof. and pivotally supported by means of a bolt 47, extending radially from the. inner side into said hinged section 41, of the shuttle is a swinging dctent 48. having a finger 49. adapted to engage in said notch. The elongated tail 50, of said detent extends oppositely from said finger around the inner periphery of said hinged segment. and pivotally mounted thereon is a lever 51, one end Lill in a suitable notch or recess in said iinge spring 53, engages the free end of said lever 51, and acts to hold the same normally in locking position, as shown in Fig. 4. hen it is desired to release the hinged section, the tail of the lever is pressed downwardly to the tail 50, of the detent, thus releasing the locking end of the lever, whereupon the ever may be swung laterally, carryirgg the finger 49, thereon out of the notch and permitting the shuttle to he opened. Mounted on the face of said shuttle at the side opposite the cresceut frame 6, ahd diametrically opposite the hinged section of the shuttle is an inwardly and laterally inclining stud shaft 54, and provided, as shown, with a face plate or co lar 55, rigidly secured thereon. Said stud shaft extends upwardly through the collar or hub 56, of said collar or face plate, as shown in Figs. 4 and 11.

Said hub is of a diameter to fit in the here or core in a paper reel 57, having the paper or other wrapping material) 58, wound t ereon, as shown in Figs. 1, 2, 4, 5 and 11, and secured on the upper end of said huh, and extending peripherally, but eccentrically around the same, are e rings 59, each at its free end provided wit an outwardl extending and slightlv inwardly incline projection 60, adapted when the reel of wrap- )ing material is pressed thereover, to spring inwardly to permit the reel to receive the hub therethrough with said springs engaging over the outer face of the reel to hold the same from displacement and afford tension. Mounted upon a bracket 61, pivotally and obliquely secured upon the face of said reel, is an edge turning or folding device 62, comprising a sheet or plate of metal bent to afford a tapering nozzle 63, comprising an narrow fold, an outer inner and relativel lip 64, integral with the wider fold, and a outer fold, and turned over the inner. The opposite. end of said nozzle is wider and.

flaring to receive the paper and other material therein, as shown in Figs. 4 and 5. Said nozzle is secured on the bracket 61, in any suitable manner, with the tapered end thereof directed outwardly and adjacent said tapered end, and set in the face 'of the shuttle, is a stud shaft (i5,that is ap )roximately parallel with the stud shaft 54. Journaled on said stud shaft, is a roller (36,

or, if preferred, the stud shaft may be providcd merely with, a rounded or convex face over which the paper, or other wrapping material, may. be drawn to set the fold therein and to direct .the strip suitably to the article to be wrapped.

Mounted upon the table at the rear of the shuttle, and rigidly secured in a bracket (37, is a standard (38, and adjustably secured on said standard in any suitable manner, is a yoke 69, having journalcd between its arms and against which t 0 top of the tire, or other annular body to be wrapped, rests,

and travels during the wrapping operation.

The operation is as follows: The machine is first adjusted to the size of the annular bodies to be wrapped, and this is accomplished by adjusting the advancing or feed- 1ng rollers 18, inwardly or outwardly toward the shuttle by means of the screw shafts 26. The yoke 69, carrying the roller 70, is then adjusted upwardly or downwardly on the standard, and outwardly or inwardly, as required, to properly support the top of the annular body, as indicated in dotted lines in Fig. 1. f not previously satisfactorily adjusted, the grooved rollers 33 and 40, are adjusted to bear upon the periphery of. the shuttle, and together with the grooved pulley 7, afford three points of contact and support for the shuttle, between which the same is rotated, said shuttle, of course, havin frictional engagement with the grooved riving pulley 7, the grooved roller 40, and one run of the belt between .may rotate through the eye of the other.

The driving belt now being shifted to the tight pulley, the shuttle is rotated at a rela tively high rate of speed, while the tire is rotated by means of the advancing rolls 18, at a suflicient rate to give the desired lead for the material wound upon the tire or coil, while the paper or other wrapping material, is drawn from the reel through the folding nozzle 62, around the'guide arm or roll 66, and thence, by the rotation of the shuttle, is wound about the tire. The operation continues until the annular body is fully wound or covered, the driving belt is then shifted to the loose pulley, the machine stopping almost instantly, the shuttle again opened, and the annular body removed and another inserted, whereupon the operation is repeated. When it is desired to replenish or to renew the paper reel, the extended ends 60, of the retaining springs on the hub 56, are pressed inwardly, thus permitting the core of the reel to be removed and another reel or roll of paper to be inserted thereon.

Details of the construction may. of course, be varied through a wide range. I have, however, shown and described but a preferred form of my invention, although numerous details of construction and operation will readily suggest themselves. I

therefore do not purposev limiting the patent granted on this application, otherwise. than necessitated by the prior art.
