HEIEEB FOB SEWING MACHINES.
The principal object of the present invention is to provide a sewing machine hem-' mer which in the case of round or tubular work will automatically get out of the way and permit of the comp etion of the hem and which will automatically return to its original position so that the hemmer will operate automatically to permit of the complete hemmi-ng of the edge of a round article of clothing or tubular fabric and of a com tinuation of the stitching, if desired, and will automatically return to its initial potion upon completion of the hem.
To this and other ends hereinafter set forth the invention, generally stated, comprises asectional folder arranged in advance of the sewing mechanism and of which one section is fixed and otwhich the other section is spring pressed and pivotally supported and adapted to be turned about its pivotal support tem orarily to one side of the line of feed by the action of the oncoming sewed art of the hem in order to clear 'the short olded portion of the fabric that precedes the completed hem so that the folded portion may run to and through the sewing mechanism. The invention also comprises the improvements to be present- 1y described and finally claimed.
In the following description reference will he made to the accompany ng drawin forming part hereof and in which- Figure 1 is a to or plan view 0t mochanism embodyin eatures of the invention showing the f0 der in normal position.
Fig. 2 is a similar view showing the movable section of the folder turned out of the line of feed.
Fig. 3 is an elevational view showing the inlet end of the folder, and
Fig. 4 is a. sectional view taken on the line 4-4 of Fig. 3 and showing in full and dotted lines two positions of the movable section of the folder. j
In the drawings the section 1 of the folder is fixed, for exam 1e, it is attached to or made part of a p ate 2 adapted to he attached to the table of a sewing machine, for exam 1e, through the intervention or a slot 3, an the sition of the sewing mechanism is indicate by the presser foot 4, shown in dotted lines, it being understood that in Figs. 1 and 2 the direction of the feed is from the bottom toward the top of the sheet.
The other section 5 of the folder is pivotally supported as at 6. The ivotal support 6 is shown as provided on t e end of an arm 7 that extends beyond the line of feed and is secured to the late 2. 8 is a spring hav- A ing one of its en s connected with the movable elementof the folder and the other of its ends connected with an extension 9 of the arm 7 which is connected by slot and screw adjustment 10, so that the tension of the spring can be adjusted. The spring 8 presses or pulls the pivotal element 5 of the folder into the position shown in Fig. 1 with its stop 11 against the arm 7, and this is the normal position of the section or element 5 so that normally the two elements 1 and 5 of the folder occupy such relative position that the device as a whole may be considered to be an ordinary folder and it operates like an ordinary folder in hemmrng round work until the Beginning of the original stitches approaches the sewing mechanism 4, when the sewed portion of the hem, operating 11 on the heel 12 and under the influence o the feed, turns the element 5 about the ivot 6 and into the position indicated in ig. 2 and by dotted lines in Fig. i. In this position the section or element 5 clears the part of the fabric which it has just folded and gets out of the way of the oncoming sewed portion of rio can reach the stitch forming mechanism 4:, thus completin the hem whereupon the spring 8 returns t e art or element 5 to its original position. T e heel of the element 5 .may be somewhat concave as shown in Fig. 4 for engagement with the oncoming sewed ortion of the hem, and the element 5 may provided at its inlet end with an upwardly curved toe 13, Fig. 3, which facilitates the described pivotal motion which is imparted to it in respect to clearin folded portion of the work. The spring 8 may be omitted and the folder element 5 turned by hand.
, It will be obvious to those skilled in the art to which the invention relates that modifications may he made in details of construction and arrangement-without departing from the spirit of the invention which is not limited as to those matters or otherthe wise than as the prior art and the appended.
' V the same and extending beyond the line of claims may require.
I claim: v
