PLAIT-FOLDER FOR SEWING-MACHINES.
Specification of Letters Patent.
Patented July 14, 1914.
Application filed January 21, 1907. Serial No. 353,285.
To all whom it may concern Be it known that I, Josnrr-r H. DE NIKE, a citizen of the United States, residing at Albany, in the county of Albany, State of New York, have invented certain new and useful Improvements in Plait-Folders for Sewing-Machines, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of reference marked thereon.
My invention relates to new and useful improvements in plait folders for sewing machines, and has for its object to provide a box plait folder which is simple in construction and which is also capable of adj ustment so that various widths of box p-laits may be formed.
My invention consists in the novel parts and arrangements hereinafter shown and described.
In the present embodiment of my invention, which is illustrated in the accompanying drawings: Figure 1 is a front elevation of a sewing machine with my improvement applied thereto, certain parts being sectioned in order to more clearly show the manner of folding the fabric. Fig. 2 is a top plan view of the work support with my attachment applied thereto, certain parts of the machine being broken away for the sake of clearness. Fig. 3 is a view similar to Fig. 2, with the fabric to be folded placed in the folder. Fig. l is a sectional side view of the folding attachment. Fig. 5 is a detail perspective view of the folding attachment, the parts being detached and separated in order to more clearly show the construction and the relation of the said parts. Fig. 6 is a perspective view of the box plait formed upon my improved attachment.
In the accompanying drawings, the bed plate 1 is of the usual construction and overhanging the same is the usual supporting arm 2 for the needles. The needle bar?) recipro-cates in suitable bearings l, 4' formed at the end of the overhanging arm 2. The needle bar 3 carries suitably spaced needles 5, 5. The needle bar is reciprocated by the usual needle lever 6, which is connected by a link 7 to a lug 8 mounted on the needle bar. The presser bar 9 carries a presser foot 10 atits lower end, which cooperates with the feed dog 11, in holding the fabric while the same is being stitched and in feeding the fabric through the machine.
All of the above parts are of the usual construction, and will not therefore, require further description.
The fabric is folded to form a box plait by suitable complemental folding and guidmg fingers which extend within the box plait and operate to determine the width of the said plait. In the present embodiment of my invention, these fingers l2 and 13 (see Figs. 2 and 5) are supported upon a bracket or base plate 14, rigidly secured to the work support. Said bracket 14 as clearly shown in Figs. 2 and 8, is composed of two arms-l5 and 16 which are adjustably secured to the work support 1 by means of screws, 17, 17 and slots 18, 18. These arms and 16 approach each other as they extend from the work support and at their outer ends are united and together form a support for the fingers 12 and 13 and the means for adjusting the same.
The support for the fingers 12 and 13 consists of two spaced plates 19 and 20, the lower one of which is secured to the bracket 14. These plates 19 and 20 are formed integral at one end and are separated at the other end by a block 21. Sliding in the space between the plates 19 and 20, is a block 22 which has a horizontally extending opening 23. An adjusting screw 24:, extends through an opening formed in the portion of the plate connecting the plates 19 and 20 and has one end thereof threaded to engage a corresponding thread in the opening 23 in the sliding block. The adjusting screw 24 has a reduced portion 25 which engages a lug 26 on the supporting bracket, whereby the adjusting screw is held from longitudinal movement. It will be apparent therefore, that when said adjusting screw is turned either the one way or the other, that the sliding block 22 is moved in a direction longitudinally of the plates 19 and 20. The fingers 12 and 13 are provided with openings 27 and 28, respectively, which edge of the fingers 12' and 13 beyond the end engage a stud 29 on the plate 19. This stud 29 serves as apivotal support for the fingers 12 and 13. The finger 12 is also provided with a rectangular opening 30, which is located in the finger a short distance forward of its pivotal support. This opening 30, is inclined to the longitudinal axis of the,
finger. The finger 13 is provided with a sim ilar rectangular opening 31, which is dis posed the same distance from its pivotal sup port as the opening 30 in the finger 13. This rectangular opening 31 in the finger 13 is however, arranged so as to incline to the longitudinal axis of-said finger in a direction opposite to the inclination of the rectangular opening 30. Tile sliding block 22 is provided with a stud 32, which extends up through the rectangular openings 30 and 31.
The fingers 12 and 13 are superposed one upon the other as above noted and extend to a position adjacent the stitching point of the machine. The finger 12 has a projection 33 extending from its forward end and in line with its'folding edge, while the finger 13 has a similar projection 34 extending from its opposite edge. When the finger 12 is superposed uponthe finger 13, the projections 33 and 34 form a cut away portion in the forward end of the box plait former, which receives the forward end of the presser foot; The object of extending the folding of'the presser foot is sothat the folded fabric may be held properly positioned practically until the same is engaged. by the needles. The fingers 12 and 13 are provided with transfer slots 35 and 36 respectively. These slots register with one another and a suitable screw 37 passing through the said slots into the plate 19'may be used to look the fingers 1.2 and 13in their adjusted positions.
-The manner of adjusting the fingers 12 and 13 will be obvious from the above description. When the adjusting screw 24' is turned" in one direction, the sliding block 22 is moved longitudinally of the said fingers 12 and 13 and as the stud 32 moves with the said block, said stud will engage the sides of the inclined slots 30' and 31 and cause the fingers 12 and 13 to be swung on their pivotal stud 29 and be thereby adjusted at an angle to each otherand the line of seam formation. This movement of the fingers 12 and 13 causes the ends of said fingers adjacent the needles to be moved closer together or farther apart, thus causing a wider or a narrower fold in the fabric. It is necessary however, to fold the fabric underneath the plate former, made by the fingers 12 and 13, and this is accomplished in the present embodiment of my invention by the folding blades 38 and 39, which are suspended above thework support or bed plate of the sewing machine. In order to provide a suitable support for the folding blades, 1 have provided a bracket 40 which is secured to the head of the machine bysuitable screws 41 41. This bracket 40 extends outwardly {from the head of the machineand bent jaround to a position infront' of the needles. Said bracket 40- carries supporting arms 42 and 43 which, are shown in the drawing as formed integral, and are secured to the bracket40 by screws 4-4 44. This blade-38 .is provided with an upwardly and out- 'wardly extending shank 45 which is secured lto the supporting arm 42 by suitable screws 46. Thefolding blade 39 has an outwardly and upwardly extending shank 47 which is secured to the supporting arm 43 by screws 48. The arms 42 and 43 extend outwardly from each other and are thus spaced so that the fingers 12 and 13 together with the fab-' ric folded over the same may pass between .said arms. The folding blades 38 and 39 however, extendunderneath the folding fingers 12 and 13 so as to fold the fabric en.- fgaged thereby around the fingers 12 and 13 as-clearly shown in Figs. 1 and 3.
I It will be noted that the folding blades 33 and 39 are spaced a less distance from each other than the needles 5, 5. It will also be noted: that these folding blades 38 and 39 are so disposed relative to the needles that the folds in the fabric formed around the blades 38 and 39 will pass between the of the folding blades relative to the needles is to bring the folded edges of the fabric underneath the box pl'ait'between the two needles so that the said edges will be secured by the stitchingthus forming and fixing the box plait.
The manner of operating my device will be apparent from the above description. The
isfed from'the fingers 12 and 13, and as it is moved into the machine, it is drawn around 'under the folding blades 38 and 39. These blades 38 and 39 are tapered-outwardly at their receiving end, in order to all'ow'the fabric to be easily fed into the folder. The fabric which is folded around the folding'blades 38 and 39, is drawn underneath said blades, and as said blades 33 and 39 are supported by the head of the machine, said fabric may pass freely under. these blades; As clearly shown in Fig. 6, the folded edges of the fabric passingfrom the folding blades are stitched and thus secured :to the body fabric. When a wider plait is .fdesired; the adjusting screw is turned so as lto spread the fingers 12 and 13. narrower plait is desired, the adjusting jscrew is turned in the opposite direction ithus drawing the fingers together.
needles 5, 5. The object of this disposition.
.fabric F in-which a box plait is-to be formed It will be noted that the controlling screw 2% for adjusting the members 12 and 13 is mounted at the end of the bracket and that therefore, the same is in a position where it may be operated without removing the fabric which is be plaited from the ma chine. This is an extremely important feature especially where material having stripes is being plaited for it is often desired to adjust. the material after the same is in the machine to properly locate the stripe in the plait. Again it will. be noted that the members 45 and at? are slotted so that by loosening the screws t and f8 said members may be adjusted laterally. The purpose of this adjustment is to locate the fold underneath the plait properly relative to the needles. With this adjustment the fold in the fabric may be located relative to the needle so that the needle will pass through the fold close to the edge and thus all unnecessary Waste in making; the box plait is avoided.
From lfig. t, it will be noted that the b *acket 14: for supporting tile central plait forming members projects outwardly from the machine and that the said members are carried by said bracket so that the forward end of said members projects over the bed plate and are in fact suspended above the work support or bed plate. It will thus be seen that the plait supporting members and the cooperatingplait folding members are all susoended above the work support leaving said support entirely free for the movement of the fabric.
Instead of supporting the bracket from the upper edge of the work plate, it is obvious that said bracket may be supported from the framework underneath the work support or even from the bench on which the machine is mounted. Therefore, in the claims where I have used the term work support, I do not intend that said claims shall be limited to the cloth plate on which the work rests.
While in the present structure I have shown both the members 33 and 34 as being moved together, it will be noted that l. may provide means for moving one of said members independently of the other. The purpose of such adjustment would be to properly position a stripe so as to properly locate the same, with respect to the ofv the box plait.
It will be obvious that many changes in the construction herein described may be made wi hout departing from the spirit of my invention.
Having" thus particularly described my invention, what I claim as new and desire to 3 secure by Letters Patent is l. A box plait folder for sewing machines, includmg in combination plait forming members, means for simultaneously ad usting said plait-forming members for different sized plaits, means for supporting said plait forming members from the work support of the machine, and folding members cooperating With the plait forming members, and means for supporting the folding members from the head of the machine; substantially as described.
