This invention relates to folders'for sewing machines and has for its object to provide a folder of novel construction adaptedmore particularly for use in the production of blind-stitch seams; andto provide a folder in which the material to be stitched may be inserted with the minimum of'eifort. 7
With the above and other objects in view, as will hereinafter appear, the invention 7 consists in the devices, combinations, and arrangements of parts hereinafter set forth and illustrated in the accompanying drawings of a preferred embodiment of the invention, from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art. In the accompanying drawings:
Figure 1 is a perspective view of part of a machine with my improved folder attached thereto, showing the material in a position to be acted upon by the stitch-formlng mech-' anism.
Figure 2 is a fragmentary sectional view taken through the presser-foot and throatplate of the machine showing the position of the folds when the material is presented to the stitch-forming mechanism.
' Figure 3 is a top plan ew of my improved folder.
Figure 4 is a sectional view taken substantially along the line 44 of Figure 3' and through the throat-plate of the machine.
Figure 5 is an elevation of the receiving end .3 of the folder.
Figures 6 and 7 are sectional views taken along the lines 6-6 and 7-7, respectively, of Figure 3.
Figure '8 1s a sectional view of the finished seam showing the positions of the threads.
Figure 9 is a top plan view of a modification of myimproved folder.
Figure 10 is-a view similar to Figure 4 showing the modified folder. Figure 11 is an elevation of the receiving end of the modified folder shown in Figure 9. Figures 12 and 13 are sectional views taken along the lines 12-12 and 13 -13, respectively, of Figure 9. I
As represented inthe drawings, the present invention is shown applied to the well known Singer overseaming machine, similar to that shown in Patent No..933,033, issued to A. Grieb, August 31, 1909, and known commercially as the Singer 81 (llass machine. This machine is constructedwith a bed 1; trim.- ming mechanism 2, reciprocating needle 3,
and loopers 4 and 5 which are located below the throat-plate and cooperate with the needle in the formation of the overseaming stitches.
Detachably and adjustably secured to the bed 1 by the screws6 and 7 is my improved folder which is adapted to make an S-shape fold at the edge of the material. 7 The folder comprises a work-supporting plate 8 to which is secured a slottedlip 9 and a tongue 10.
The lip 9 extends over the work-supporting 1 plate 8: and has a supportin depending wall 11 which has its lower edge 'Xedto the worksupporting plate 8. The wall 11 is inclined towards the stitch-forming mechanism from the work-receiving end to the delivery end and serves as a guide for theedge of the material as it passes through the folder. The
slot in thelip 9 is defined by the side-walls 12,
13 and 14, the wall 13 being inclined downwardlyand inwardly towardsthe delivery end of the folder (Figures 6 and 12) so that it forms the lower limb of the 8-fold and directs the lower limb of the fold to the stitchforming-mechanism so thatit will be split by theneedle. y
The tongue 10 is the plate 8 and extends up through the slot in the lip 9. The upper edge of the tongue is bent so as to extend over the lip 9 and is so formed that the-material "is forced outwardly thereby forming the upper limb of the S-shaped fold. I I
An arched strap ldhavingits ends fixed -to the lip 9 at the delivery end of the folder bridges the slot and serves as a support for the overhangingextension 9 of the lip.
Extending from the delivery end of the folder and fixed to the supporting plate 8 is a guiding member 17 which engages the outer'surface of the lowerlimb of the S shaped fold and guides it accurately to the stitch-forming mechanism. I
- Figures ,9-13, inclusive, show a modifioaalso made integral with by a tongue comprising a rectangular'conduit 20 having a slot 21. The rectangular conduit 20 is bent in the form of an arc of a circle and extends through the enlarged part of the slot iii the lip 9 withits receiving end terminating below the supporting plate 8, The folder shown in Figures 9 to 13; inclusive, lnay be used to form" the 3-,
shaped fold shb'wn in Figure 2 if desired a tape may be fed through the conduit into the upper limb'of the S-shaped fold.
To load the folder thematerial c is placed on the supporting platB and forced inwardly in the diiiection of the stitch-forming mechanism.- lVheno the; material enters the folder its leading edgeis forced up through the slot in the 11p 9 by theot'ongue 10 or 20, as the case may be. As the material "continues to mbve towards .the stitch-forming mechanism the walll? of thGSlOtllLtllE lip 9 forcesth'e material inwardly under the overhanging edge. of the tongue thereby forming the limb A (F igure 2) and the overhanging edge 15 of the tongue forces the inate'rial outwardly thereby forming theilimb B (Figure 2) of the fold; Tlie folder delivers the folded material to the presser fom 23 which 'coacts with the feed-dog Q4 tofe'e'd the work to the trim 'mi'n g mechanism 2; which trimsth'e edge a "of the material, andthence to the "stitchiforming mechanism The folded material is presented to the stitchiorining mechanism that the needle will pass through the edge pertibn a and into and out of the lower limb A at the materialm's clearly shown in Figure '2, thereby securing the edge a to the of the material by stitches which pass into and Ora M are body or the material an the same f si 'de thereof, and which covers the edge a of material, as clearlyshown in From the foregoing description considered in "connetibh with the accompanyinf drawings, the construction, and a" vantages of my improved folderwill be clearly finders'tood; It is apparent that such and "scope of the appended claims.
Having thus set forth the nature "of 'the invention, what I claim herein is V V 1, A folder adapted to makea'n s sh a-ped fold at the edge or material and comprising weir-supporting plate, a lip provided with a slot overlying said plate, and a tongue extending through said slot and overlying a portion of said lip. V I A Told'e'radapte'd to make an s-shaped fold at the edge of material and comprising a work-supporting plate, a lip overlying said plate, said lip being provided with a slot and with a depending wall which has its lower edge secured to said plate, and a tongue extending up through said slot and overlying portion of said lip.
3. A folder for sewing machines comprising a work-supporting plate, a lip overlying a portion of said plate, spaced walls 011 said lip defining a slot, a tongue secured to said plate and extending up through said slot, said tongue having its upper edge bent so as to overlie a portion of said lip.
4. A folder for sewing machines comprisinga work-supporting plate, a lip provided with a slot overlying aportion of said plate, a tongue extending through said slot and having its u )per edge overlying a portion of said lip, and a guide fixed to said plate at f the delivery end of said folder.
5. A folder adaptedtoniake an S-shaped fold in the edge of material and comprising a work-supporting plate, a lip overlying a portion of said plate, said lip being provided with spaced walls defining a slot, one of said walls being inclined downward and inward- 1y for forming-the lowerlimb of said fold, and a tongue secured to said late, said tongue having its upper edge disposed in overlying relation to the inclined wall of said lip for forming the upper limb of said fold.
6. A sewing machine including in combination, stitch-forming mechanism and a fol'der'forforming a three-ply fold in the ,edge of material andpresenting the fold to through said slot.
7. A folder for sewing machines comprising a work-supporting plate, alip provided with a slot overlying said plate, and a tongue extending through said slot and overlying a portion 01 said lip, said tongue being in the form of a conduit. Y
'8. A folder for sewing machines comprising a work-supporting plate, a lip provided with a slot overlying said plate, a conduit ex- .tending up through the plate and through the slot in the lip, said conduit serving as a tongue over which the material may be folded; 7
9; A folder for forming an S-sha-ped fold at the edge of material comprising a work- ,su'ppor'tin-g plate, a lip provided with a slot overlying said plate, and a tongue extending up through said slot and overlying a portion of said lip, said'tong'ue affording means for leading a tapeinto the upper limb of said 'S-shaped fold.
In testimony whereof I have signed my name to this specification.
