TUBE SEWING AND TURNING' MACHINE.

To all whom it may concern:

Be it known that I, JOSEPH Pennant, a citizen ot' the United States, residing at Versailles, in the county of Morgan and State ot Missouri, have invcuted'new and useful Improvements in Tube Sewing and Turning Machines, ot' which the following is a specification.

This invention relates to new and useful improvements in apparatus for sewing and turning tubular bagging at'ter the meeting edges are brought together and stitched and aiiords a simple and eflicient automatic v.means whereby the tubing, the seam of which is stitched by a machine, may be drawn through the ring or ellipse and held by means of a suitable stretcher mechanism, after which it is wound upon a reel.

The invention comprises Various details of construction and combinations and arrangements of parts which will be hereinafter fully `described and then specifically defined in the appended claims.

My invention is illustrated in the accom-4 panyingidrawings, in which Figure l is a perspective View of the ap# paratns embodying the .features of my invention. Fig. 2 is an enlarged detail perspective view of the ring or disk through which the tubular fabric after having been stitched is drawn and the stretcher arm. Fig. 3 is a top plan view of one form of stretcher arm. Fig. 1l is a View iu elevation showing a modified form of the stretcher bar in which spiral springs are utilized in connection with the telescoping sleeve carrying a wheel for engaging the seam after -having been sewed. Fig. 5 is a detail perspective view ot an idler mechanism -to cause the belt to draw taut and insure the tubing beingwound properly upon the reel, and Fig. 6 is a sectional view on line 6--6 of Fig. 5.

Reference now being had to the details of the drawings by letter, A designates a table to the edge of which is tastened, as at B', a rigid rod B which preferably is curved over the top of the table as shown, and thence extends forward to a location, preferably slightly beyond the end of the table and terminates in a ring or disk C, which ring may be flattened or oi' any desired shape and preferably rounded upon the bearing edges a ainst which the tubing draws 1n a manner nich will be hereinafterfully described.

over the top of the table to a suitable locai tion. Fastened to the bar E is a block F and to which a resilient stretcher armG is fixed, said arm being spaced apart :trom the bar E a short distance, preferably one inch for ordinary work, and at the end ot said arm G is journaled a wheel Il, the circumterence of which is grooved and adapted to receive the seam of the tubing after the latter has been turned. A. wheel K, preferably with a convexed edge, is journaled in the free curved end of the bar or rod ll and provided for the purpose of causing the tubing to be drawn taut as it is wound upon the reel, which will be presently described.

An adjusting member, designated by letter I, is )rovidcd with two apertures, one designate( by letter L :for the reception of the bar E and the other the resilient arm G, as shown clearly in Fig. 2 and all'ordiug means whereby, as said member is moved toward the free end of the rod E, said stretcher arm may be drawn toward the bar or rod E to regulate the tension ot' the wheel carried thereby against the seam ot' the tubing. A slight depression, designated by let ter J, preferably of a depth suilicient to receive the scam ol the tubing, is lormedin the ring or ellipse for the purpose oi receiving the seam and guiding the tubing therein as the latter is being turned.

sev

lVound upon a reel L which is vertically l disposed and journaled at its lower end upon the table and its upper end in a bracket arm L is the cloth or fabric N from which the tubing is to be formed. Said reel may be positioned at any suitable location, preterably as illustrated, the two edges ot' the cloth .being drawn togetlier, one edge passing hand or any suitable nuehanisni.

bracket plat-es M upon-the table are the rollers O, between which the folded tubing` passes, being frictionally drawn or fed .tor-

ward by saidrollers. Said folded tubing passes between the rollers U, thence extends to and winds about the reel R journaled in suitable bearings in the [standards l. A pulley R is tixod to the spindle ot the reel and abelt R2 passes about the pulleyv R and also one part of the double pulley R3 journaled upon the standard l and power is applied to the pulley It through the inediuin of the belt O3 which turns about a pulley Rl upon the sewin` machine, asshown clearly in Fig. l of the drawings'7 power being applied to the pulley upon the. sewing machine-"through the medium of the vertically disposed belting interposed between therollersl O and the reel it is an idler Q, the spindle ends of which are `iournaled in the.spring-pressed blocks Q2 movable wi thin the standards Q3. rising from the table. A pulley Q" is fixed to and moved with the spring-pressed block Q2 and bears against the belt- 03.

.ln Fig. si. oiC the drawings, l have shown a slight modification ot the invention in which a spiral spring 5 ls attached to the Astretcher bar or rod 'l and S designates a sleeve telescoping within the lateral exten-` sion ot the stretcher bar and having jourvnaled therein the grooved wheel t3, thus at 'tording a slightly modified means for holding the wheel securely against the seam. Said spiral spring should be ot' such a strength as will Vtirinly stretch thefabrie to hold the same taut and 'without its being torn. lVhere a less tension is required upon delicate fabric, lighter springs may beeinployed for regulating the pressure bearing against the saine.

The operation of my invention will be readily understood and is as follows:-'l`he cloth or other vit'abric. to be converted into tubing is placed upon the reel L, the two loi'igitudinal edges o they cloth brought together, one edge passing over and the other edge passing` under the rod B which terminates in a ringv or disk C, then under the arm olf the sewing machine and stitched together, the two edges being held and guided by the Atte1 i 'portion of the tubing' has been stitched, it is drawn over the ring or ellipse C, through the latter and over the ends of the stretcher bar and gspring;` and ted between the rollers O which serve to :feed the cloth for stitching and also for reeling' up after the. tubing has been stitched. the rollers draw the `tub ing:v rearward.' the edges of the cloth are brought underneath `the sewing machine and stitched; and`v as` the tubing' passes over the' marginal edge ofthe ring, it is turned outside in, the seam dr 'wing through the offset formed inthe ringffaiithby the provision of l the stretcher arms, the necessary tension may bel applied to the 'seam 'and also at a' location (.l-iainetrically opposite to hold the tubing taut, the latter being guided by a grooved' pulley in the resilient stretcher arin. ln the evenil olf there being slack in the tubing behind the rollers the idler Q will serve to hold the same taut and to cause the tubing to wind smoothly upon the reel R.

It' desired to sew `tnbings of different diameters, bars having rings of the desired diameter may be employed and also lreels and rollers of corresponding size.

Frein the foregoing, itwill be noted that, by the provision of an apparatus as shown and described, a simple and eilicient n'ieans is a'ti'orded whereby' tubing may be formed and automatically reversed andwound upon suitable reels or, it desired, may be fed to printing machines or presses for further op eration, after which. the tubing' may be eut into suitable .length and bottoms sewed.
