PEARL J, WENTWORTH, OF FORT THOMAS, KENTUCKY.

METHOD OR PROCESS OF LAYING AND SECURING SOLES TO UPPERS.

Application filed June 8, 1917.

To all whom it may concern Be it known that I, PEARL J. VVnN'rwoRTH, a citizen of the United States, a resident of Fort Thomas, in the county of Campbell and State of Kentucky, have invented new and useful Improvements in Methods or Processes of Laying and Securing Soles to Uppers, of which the follow ing is a specification.

My invention relates to improvements in the method or process of laying and securing soles to uppers, the principal object being a simple and effective process of pressing an outsole of an upper with an adhesive therebetween, the pressure being continued a sufficient length of time to enable the adhesive to set.

Another object is the provision of such a process wherein an elastic band is utilized by wrapping the same about the sole and upper so as to afford a continuous pressure over the sole so as to accomplish the leveling of the same, and also to hold it against the upper until the adhesive, which has been placed therebetween, sets.

To the accomplishment of the foregoing and such other objects as may hereinafter appear, my invention consists in the various steps and operations hereinafter described, and thensought to be defined in the appended claims, reference being had to the accompanying drawing forming a part hereof, and which illustrates the various steps or stages of my new process or method, it being understood that these may be varied in practice within the scope of the claims without digressing from my inventive idea.

In the drawings,

Figure 1 represents a bottom perspective view of a lasted upper, with the heel and sole applied thereto, and being held in position by means of an elastic band, which has been wrapped therearound;

Fig. 2 is a similar view of a slightly dif ferent form of shoe, and

Fig. 3 is a similar view to Fig. 2, the elastic band only being partially wrapped around the shoe.

In carrying out my process, I utilize the last 1 on which the upper 2 is lasted. This upper may be of any standard form and construction. On this lasted upper is applied the outsole 3 which may or may not have the heel 4, depending upon the character of shoe being made. This outsole 3 Specification of Letters Patent.

is placed in position on top of the lasted upper with a suitable coating of adhesive or adhesive material, placed therebetween.

In order to permit this adhesive to set so as to properly secure the outsole on the lasted upper, and also to lay and level the out sole on the lasted upper, it is necessary tr, apply pressure thereto, and to continue this pressure until the adhesive has set, when the outsole will be accurately leveled and effectively secured to the lasted upper.

I apply this pressure preferably by means of an elastic band, this being preferable in the form of an elastic fabric webbing, although it is to be understood that other forms of suitable elastic material may be utilized. The preferred manner of applying this elastic band is perhaps best illustrated in Fig. 3. One end is tacked or otherwise secured as at 5 to the heel portion of the upper and the band is then placed along the top of the sole as at 6, and then around the edge portion of the ball and toe as at 7 and 8 so as to engage both the sole and the upper of this part of the shoe. The band is then turned over the bottom of the shoe near the shank as at 9 and brought entirely around the upper as at 10-, this spiral being continued and the band wrapped around the toe as at 11, the

wrapping continuing as at 12 and 13 in a spiral manner to the shoe until the other end is secured to the last as at 14.

as seen in both Figs. 1 and 2, it is obvious that the elastic band practically covers the entire area of the outsole and holds the same with a yielding pressure, securely against the upper. Due to this yielding pressure the sole is leveled to the lasted upper so that it conforms exactly to the shape of the last. This pressure is also of sufficient strength to securely hold the sole to the upper while the adhesive is setting. When this adhesive sets, the elastic band may be removed and the shoe is complete. The length of time necessary for the adhesive to set, depends upon the characteristics thereof, it being preferable, of course, to use a quick setting adhesive in the interests of expediency.

What I claim is:

1. A method or process of laying and securing soles to uppers, including providing a lasted upper, placing an outsole thereon with an adhesive therebetween, and wrapping an elastic member about the sole and upper beginning at the heel portion of the upper, extending along the sole and around the edge of the ball and toe portion of the sole so as to engage both the sole and upper, then around the entire lasted shoe and over the toe portion thereof and thence spirally around the lasted shoe to the rear end thereof, so as to apply a continuing pressure. 7

2. A method or process of laying and securing soles to uppers, including providing a lasted upper, placing an outsole thereon With an adhesive therebetween and applying a continuing pressure to the sole by means of a member Wrapped around the sole and upper with portions of said member extending substantially cross-Wise of the sole and another portion extending substantially lengthwise of the sole.
