SPECIFICATION forming part of Letters Patent No. 646,962, dated. April 10, 1900. Application led February 5, 1900. Serial No. 3,984. (No specimens.)

To a/ZZ whom it may concern.'

Beit known that l, RICHARD Dovn, a citizen of the nited States, residing in Westville, in the county of Gloucester and State of New Jersey, have invented certain new and useful Improvements in Methods ofv Forming Sacks for Suspensory Bandages, of which the following is a specification.

My invention has relation to a method of forming sacks for use in suspensory bandages, and in such connection it relates to the various steps constituting such a method.

The principal object of my invention is to provide a method of forming seamless sacks of requisite shape for use in suspensory bandages and to this end myinvention primarily consists of a method comprising the following steps: first, in forming a sheet or blank of knit or woven fabric; second, doubling said sheet or blank and stitching or otherwise uniting the sides to form a tube; third, drawing in the lower end of the tube until the unseamed side approaches the seamed side of the tube to form a bag or sack; fourth, stretching the bag or sack thus-formed over a suitable Shaper or former and fixing the form of the same under heat and pressure; and, finally, cutting the formed bag or sack on aline parallel with its seamed edge and binding the two edges thus formed and the neck-or top opening of the bag or sack.

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in whichm Figure l is a side elevational view of the blank or sheet from which the bag or sack is to be formed. Fig. 2 is a side elevational view of the sheet folded and having its edges united to form a tube. Fig. 3 is asimilar View of the tube after its lower end has been drawn in to form a bag or sack. Fig. 4; is a similar.

view of the bag or sack stretched over the shaper or former, and Fig. 5 is a perspective view of the finished article.

In carrying out my method a sheet or blank a of elastic knit or woven fabric is first formed. The textile sheet or blank a is then folded and its edges a'az united, as at a3, by stitching or other means to form a tube.

A drawing-string a4 is worked in the lower edge of the blank a, and a similar drawingstring a5 is also preferablyworked in the upper edge of said blank. After the tube has been formed the lower edges of the tube are drawn inward by means of the string d4 until the unseamed side a approaches the seamed side a3, as illustrated in Fig. Si. The

bag or sack thus formed is then stretched over a Shaper or former b and under heat and pressure is fixed into required shape. l/Vhen placed on the former, the tucked-in end @Gis smoothed out into a regular curve a7, and the untucked portion a8 of the end is drawn around until it is in alinement with the edge a3 of the tube. The upper edge of the sack during the shaping on the former is drawn upward in an oblique line 0.9, as indicated in Fig. 4.

After being formed on the shaper the bag or sack is cut along a line parallel with the seamed edge a3 and also on aline sulbstan tially at right angles to the oblique upper edges of the sack. The edges thus formed parallel with the seam a? are afterward bound with a band of non-elastic material, as indicated at din Fig. 5, and the inclined upper e lges are also bound, as indicated at d. The portions cl2 formed by cutting at right angles to the inclined upper edges are preferably left unbound. The binding d and d prevents the return of the elastic fabric to its original shape. Y

The sack thus formed possesses many advantages, among which may be enumerated the following: It has no seam and readily retains its shape. Itis easily formed and adapts itself to the parts to be supported wit-hout chaing or irritation.

Having thus described the nature and 0bject of my invention, what I claim as new, and desire to secure by Letters Patent, is-- l. The herein-described method of forming sacks for suspensory bandages,which consists in first forming a blank of suitable elastic teX- tile material; second, uniting the edges of said blank to form a tube third, drawing in the lower edge of said tube to form a bag or sack; fourth, stretching the bag or sack thus formed upon a Shaper or former and fixing the shape thus formed under heat and pressure, and

ICO

cutting the formed bag orsack on a line parallel with the seained edge; and Iinally, binding the edges thus formed with a non-elastic binding, substantially as and for the purposes described.

In testimony whereof I have hereunto set my signature in the presence of tWo subscribing witnesses.

RICHARD DOVE.
