PACKAGE.

Specification of Letters Patent.

Patented May 6, 1919.

Application filed August 30, 1917. Serial No. 189,013.

To all whom it may concern 7 Be it known that \VILLTAM M. WHEILDON, a citizen of the United States. and a resident of Ashland, in the county of Middlesex and Commonwealth of Massachusetts, has invented an Improvement in Packages, of which the following description, in connection with the accompanying drawings, is a specification. like characters on the drawings representing like parts.

This invention relates to packages, and in particular to that form of package wherein an article is inclosed in a helical wrapping of strip material. usually paper, and the object is to provide a cheap and easily applied form of wrapping which will be exceedingly strong and wear resisting.

My invention will be best understood by reference to the following description taken in connection with the accompanying drawings, wherein- Figure 1 is a side elevation of a tire partially inclosed in a wrapping embodying my improvements Fig. 2 is a view on an enlarged scale of a portion of the wrapped tire with parts broken away and some of the convolutions of the wrapping unwound more clearly to show the construction:

Fig. 3 is a detail in circumferential section taken at the inner circumference or bead portion of the tire. The thickness of the wrapping is necessarily greatly eiaggerated in this figure and gives the whole a 85 roughness and the parts an irregularity of appearance which would not be apparent in practice.

In the embodiment. of the invention chosen for purposes of illustration, the

wrapping is applied to an annular article and in particular to a tire, and for conveniencc in description I shall refer specifically to a tire herein. The tire 5 is covered by a paper strip wrapped helically around the same, and I have herein shown the use of two paper strips. The strip 7 is shown in red and the second strip 9 is applied over the strip 7. breaking joint with the same. Preferably the adjacent spires or convolutions of the 0 strip 7 are disposed in non-overlapping relation at the tread of the tire. Herein (Fig. 2) the edges substantially abut at the tread. and to compensate for the difference in circumference between the tread and bead por- 66 tions of the tire, the convolutions will overlap at the beads as seen in Fig. 3. The second strip 9 is conveniently a sealing strip, and may be provided with an adhesive coating 11 so that it may seal together the edges of adjacent convolutions of the wrapping strip 7. A wrapping of the kind described may be conveniently applied by the improved form of machine shown in a jointapplication of myself and Edward H. Angier. Serial No. 153.992,- filed March 10. 1917. I prefer to utilize the covering embodying two strips because it is possible to work with greater speed than in the case of a single strip. and because the production of a sealed package is facilitated, since the application of adhesive or the moistening thereof. whether to the strip 9 or its edges or the edges of the strip 7, is as it were balanced so that stretching of the paper consequent on the moistening thereof does not introduce any difficulty in the process of its application.

In order to reinforce the package so that it will be more durable and less likely to be broken through spreading of the tire beads when the tire undergoes shock, I provide for reinforcing the same with a reinforcing strand incorporated in the joints of the helical wrapping. In the present instance I have shown two funicular reinforcements in the form of cords 13 and 15, which parallel respectively the edges of the strips 7 in such position as to be overlaid by the sealing strip 9. I prefer to utilize two cords, as shown. in order to equalize the tension of application. These cords may be conveniently applied in the operation of wrapping the tire by providing suitablesupplies of cord on the wrapping shuttle and proper guides of fair-leaders for guiding the ends to the joints between the wrapping strips. It will be understood that the strip 7 and its cords are wrapped on about a turn in advance of the sealing strip 9. which follows after and seals together adjacent edges of the strip 7, and which in the operation will cover the cords disposed adjacent those edges and incorporate them in the joint. If desired, he cords may be coated with a suitable adhesive in the operation of applying them to the tire.

Referring to Fig. 2, 7 and 7" represent adjacent convolutions of the wrapping strip, the convolution 7 overlapping the convolution 7" at the interior circumference of the tire. At 13 and 15 are shown those portions of the cords pertaining to the convolution 7 and at 13 and 15 the next turn of the cords pertaining to the convolution 7. It will be,noted that at the tread of the-tire the cords 15 and 13 are together in position to be covered and incorporated in the sealed joint by the wrapping strip. In Fig. 3 the position of parts at the inner circumference of the tire is shown. The convolution orspire 7 has the turns or spires of the cords 13 and 15 paralleling itsedges. The turn of the strip 7 in the present instance overlaps the edge of the strip 7*, and its associated cord 15, and the turn 7 has on the exterior thereof the turns of cord 13 and 15*. A turn 9 of the sealing strip secures together the overlapping edges of the turns 7 and 7 and also incloses the turn of the cord 13".

' I am aware that it has been proposed to wrap annular articles with a helical strip and also to apply a cord around the wrapping which would, as it were, tie it down, but this I do not claim. My invention contemplates the incorporation of the reinforcements in the joints between the turns of the wrappin and in particular the provision of a sea ed package having reinforced joints. It is now customary to wrap tires with paper strips consisting of two thicknesses having longitudinal reinforcing threads interposed therebetween. Obviously a double quantity of material is used and it is material which must be specially prepared beforehand. In accordance with my present invention, ordinary paper strip may be utilized, and the reinforcement incorporated without additional expenditure of time at the same time that the wrapping is put on the tire.

As will be readily understood from the showing at the right of Fig. 2 and in Fig. 3, if the wrapping is pressed down about the article the strips may be locked over the reinforcing cords to form a mechanical joint which, independently of the adhesive securing together adjacent convolutions, desirably reinforces the package and prevents relative shifting and displacement of the turns of wrapping strip.

Having described in detail a single embodiment of my invention, what I claim as new and desire to secure by Letters Pat-' ent is l. A package comprising an article and a wrapping inclosin the same in a plurality of helical convolutions-overlapping and adwrapping strip helically encircling the same,

strands paralleling the edges thereof and a second helical strip breaking joint with the first and overlying the edges thereof and said strands.

4. A package comprising an article, a wrapping strip helically encircling the same, strands paralleling the edges thereof and a second helical strip breaking joint with the first and overlying the edges thereof and said strands, the overlapping parts being adhesively secured together.

5. A package comprising an article, a pair ofhelical wrapping strips encircling the same, breaking joint and with their edges joined and a funicular reinforcement incorporated in the joint.

6. A package comprising an article and a wrapping encircling the same in a plurality of convolutions having overlapping edges joined together and a funicular reinforcement at the joint.

7. A- package comprising an annular article, a wrapping strip helically encircling the same, the edges of the convolutions thereof lying in non-overlapping relation at the greater circumference of the article, a second helical strip having convolutions breaking joint with those of the first, overlying said edges and secured thereto and a funicular reinforcement in the joint between said strips.

8. A package comprising an article and wrapping inclosing the same in a plurality of helical convolutions having lapping edges and a strandv along the underlying edge, the overlying edge interlocking with said strand.

9. ,A package comprising an article and wrapping inclosing the same and comprising a helically applied strip having strands along its edges and a second strip breaking joint with the first and interlocking with said strands.

In testimony whereof, I have signed my name to this specification.

WILLIAM M. WHEILDON.
