10 Claims. (Cl. 112-136) This invention relates to pleat-forming devices.

It is an object of the present invention to provide a pleat-forming device which will render the formation of pleats in garments entirely automatic.

It is another object of the present invention to provide a pleat-forming device of the above type which will facilitate and quicken the formation of pleats in garments prior to sewing the same.

It is still another object of the present in-- vention to provide a pleat-forming device of the above type which will insure accuracy in the formation of the pleat.

It is still another object of the present invention to provide a pleat-forming device which may be conveniently mounted adjacent a sewing machine and which will materially increase the production of pleated garments by the operator.

Other objects of the present invention are to provide a pleat-forming device of the above type which is of simple construction, inexpensive to manufacture, has a minimum number of parts, is easy to use and efiicient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Referring more in detail to the drawing, in which similar reference numerals identify corresponding parts through the several views, there is shown a pleat-forming device, referred to collectively as l5,and including a bracket I6 of L- shaped cross section, substantially as illustrated.

The bracket 16 consists of a horizontal base portion l1 and a vertical portion I8, the latter having a longitudinal cut-out portion l9 extending to one end thereof and a tapered portion 20 at the other end.

The base portion ll adjacent the tapered portion 20 is provided with a plurality of countersunk openings 2| permitting the bracket Hi to be secured to the top of sewing machine table 22 or other tables by means of wood screws 23, substantially as illustrated in Figs. 1 and 2. It

i will be noted that the major portion of bracket l6 extends outwardly from table 22 at an angle thereto, for a purpose which will hereinafter become clear.

The base portion I! at the end remote from the openings 2| is provided with a plurality of longitudinally spaced, internally threaded openings 24, and intermediate the openings 24 and 2| is provided with an opening 25.

The vertical portion I8 intermediate the cutout portion l9 and the base portion I! is provided with a pair of longitudinally spaced, vertically elongated openings 26 and adjacent the inner end of cut-out portion [9 with an opening 21. The vertical portion l8 below the inner end of tapered portion 20 is also provided with a pair of longitudinally spaced, internally threaded openings 28. The outer end of tapered portion 20 is cut-out, as at 29, providing an ear 30 having an opening 3|.

An elongated plate 32 is disposed alongside vertical portion l8 and is provided with openings 33 adapted to be aligned with the openings 28 in vertical portion I 8 (see Fig. 3), the plate 32 a cut-out portion 34', for a. purpose which will:

hereinafter become clear.

, One plate 35 of a hinge 36 is disposed alongside the bottom of plate 32 and is provided with openings 3? aligned with the openings 33 and 26 in the plate 32 and vertical portion 18, re spectively (see Fig. 3), the plate 35 extending the length of plate 32 in coincided relationship there with, permitting the other plate 38 of hinge 33 to be rotated upwardly into parallel relation with plate 32, as shown in Fig. 7.

The plate 38 at its outer end is provided with a cut-out portion 39 adapted to be aligned with the cut-out portion 34 of plate 32.

One plate 43 of a second hinge 4! is disposed alongside the other side of vertical portion l8 and is provided with openings 42 aligned with the. openings 33, 25 and 31 in plate 32, vertical portion I8 and plate 35, respectively (see Fig. 3) ,the plate extending the length of cut-out portion ii! in coincided relationship with vertical portion l8, permitting the other plate 43 of hinge M to be rotated upwardly into parallel relation with vertical portion Ill, as shown in Fig. 7'.

The plate 43 at its outer end is provided with a. cut-out portion 24 adapted to be aligned with the cut-out portions 34 and 39 of plates 32 and 38, respectively.

Bolts 45 are located in aligned openings 42, 33, 26 and 31 and are secured therewithin by means of nuts 46, washers 4'! being provided intermediate the heads of bolts 45 and plate 35, while washers 4B are provided intermediate the nuts 4t and plate 40.

A hearing member as is provided with openings aligned with the openings 23- in vertical portion l8, and is secured to the latter by means of screws 5| passing through the openings 50 and 28, as shown in Fig. 4.

An elongated member 52 of U-shaped cross section is provided, and is adapted to receive the top edge of plate 32 therebetween in freely spaced relationship, as shown in Fig. 3.

The top of bearing member 49 is provided with an opening 53, and is received within thev member 52, substantially as illustrated in Fig. 4, the member 52 being provided with openings 54 on each side aligned with the opening 53. A screw 55 passes through the aligned openings 53, 54 and is secured therewithin by means of a nut 56, a washer 51 being provided intermediate the nut 55 and the outer side of member 52 while a washer 58 is provided intermediate the bearing member 49 and the inner side of member 52, as shown in Fig. 4.

Thus the member 52 may be rotated down onto plate 32, as shown in Figs. 3 and 6-9, or rotated to the raised position of Figs. 1, 2 and 5, in which latter case the bottom edges of the member 52 near the rear end thereof will abut the tapered portion 20.

The member 52 at the inner end of its central or back portion is provided with an opening 59 which receives one end of a contraction spring 60, the other end of spring 60 being received in the opening 3! at the inner end of vertical portion l8 whereby to normally retain the member 52 in a raised position.

As a means of moving the member 52 down-- wardly onto plate 32 for a purpose which will hereinafter become clear, the member 52 is pro vided on each side with transversely aligned openings 6| which are also aligned vertically with the opening 25 in base portion ll. An elongated eye-bolt 62 passes upwardly through openin 25 nd is'bent at right angles to itself. as at 63; the portion 63 passing through the openings 5! and being-externally threaded whereby'to receive 15 4 thereon a nut 64. The eye 65 of eye-bolt 62 extends downwardly below the base portion IT, where it receives the end link of a chain 66. The other end of chain 66 is connected to a foot-pedal 6! hingeably mounted on a base plate 58, as shown in Fig. 2. The pedal 61 is normally retained in the raised position of Fig. 2 by means of an expansion spring 59 intermediate the former and the base plate 68, preventing tensioning of chain 36 until the pedal 6? is actually pressed down with the foot.

Thus, when the pedal 61 is pressed downwardly against the action of spring 69 by one foot of the operator seated at sewing machine table 22, the member 52 will be moved downwardly onto plate 32- against the action of spring til, as will be obvious.

The inner ends of hinge plates 38 and 43 near their top edges are provided with openings 10 which receive the ends of a spring wire H, the latterpassing through the opening 2'6: in vertical portion l8. Thus, the spring wire 1! will retain the plates 38 and 43 in normally spaced rotation from plate 32, as shown in Figs. 1-3 and 5 and 6, for a purpose which will hereinafter become clear.

As a means of limiting the upward displacement. of member 52 to a point just before the lower edges of the member come into contact with tapered portion 20, an inverted U-shaped guard i2 is provided, the latter at one end being integrally formed with a base portion 13 bent at right angles thereto, as shown in Fig. 1. This base portion 13 is provided with a pair of longitudinally spaced, elongated openings 14 adapted. to be aligned with the openings 24 in base portion l'i. Screws 15 pass downwardly through the aligned openings l4 and 24 and are secured therein by an internal thread provided on the latter, thus mounting the guard 12 on base portion ll. Washers 16 are provided intermediate the heads of screws l5 and base portion l3. By loosening the screws 15, the guard 12 may be adjusted longitudinally by means of the elongated openings 14, permitting the limitation of the up- 5 ward movement of member 52 to be adjusted, as

will be obvious. If it is desired to adjust the guard 12 longitudinally beyond the limits of openings 14', the screws F5 may be removed and inserted through the openings T4 into the adjacent pair of openings 24, as shown in Fig. 1.

It will be noted that the vertical sides of guard 12 also serve to limit the outward rotation of hinge plates 38 and 43 under the action of spring wire I l.

The upper, central portion of guard 22 is bent at right angles to itself, as at H, providing a palm rest for a hand and avoiding the presence of a sharp upper edge for the guard, as will hereinafter become clear.

In operation, the garment to be leated i8 is passed intermediate the member 52 and plate 32, in front of guard 12, as shown in Fig. 5. The member 52 is downwardly moved as shown in Fig. 6 by pressing the pedal 6'! with one foot,

providing a U-shaped pleat '19 in the material.

If only one pleat is desired, the material is grasped on both sides of cut-out portion 34 of vertical plate 32, as shown in Fig. 8 and slid 1ongitudinally out from plate 32'without raising the member 52 or pedal 61.

The manner of removing the material is also illustrated in Fig. 9.

The pleat 18 thus formed is sewn in place.

by a sewing machine 8.11 located on table. 22.

If instead of only one pleat 19, it is desired to add another pleat 8!, before removal of the material 18 from the device and while the member 52 is still retained in the down position by pedal 61, hinge plate 38 is rotated upwardly manually against the action of spring wire H through the material, as shown in Fig. 7. The material and more particularly pleats l9 and 8| are grasped then on both sides of aligned cut-out portions 34 and 39 of plates 32 and 38, respectively, and slid off the plate 32 longitudinally without releasing plate 38 or member 52, as shown in Fig. 9. The pleats l9 and BI thus formed are then sewn in place on machine 80.

If, however, it is desired to provide three equal pleats 19, 8| and 82, both hinge plates 43 and 38 are rotated upwardly through the material, as shown in Fig. 7, retaining the member 52 in the down position by pedal 61. The pleats 19, BI and 82 are then grasped between the thumb and index finger of the other hand within the aligned cut-out portions 34, 39 and M, and the material slid off the device, as shown in Fig. 9, while the member 52 and plates 38 and 43 are retained in engagement with vertical plate 32. The pleats 19, 8| and 82 thus formed are then secured in place by stitching 83 (see Figs. 10 and 11).

Thus, it is only necessary to pass the material 58 intermediate the member 52 and plate 32, step on pedal 61, rotate the hinge plates 38 and 43 together with the fingers and then grasp the pleats thus formed within the cut-out portions 34, 39 and 44, and slide the material off and stitch the pleats.

It will be noted that not only are the pleats accurately and quickly formed, but that any number of pleats may be formed from one to three without adjusting or changing the construction of the device in any way.

It should now be apparent that there has been provided a pleat-forming device which may be conveniently mounted adjacent a sewing machine and which will materially increase the accuracy and production of pleated garments by the operator.

While various changes may be made in the detailed construction, it shall be understood that such changes shall be within the spirit and scope of the invention as defined by the appended claims.
