Definitions

  • This invention relates to sewing machine attachments and more particularly to means for securing the attachments to a sewing machine.
  • attach ments such as hemmers, sewing gauges and seam guides.
  • attachments are only intermittently used. For example, during themorning an operator may be solely. interested in sewing in the hemsof garments while in the. afternoon the same operator may devote her time to seaming the garments. Therefore, in the morning it is necessary to attach the hemmer to the sewing machine and in the afternoon it is necessary to replace the hemmer ,with a seam guide Most present day attachments are secured to the machine by means of screws or similar fastenings.
  • attachment-securing operations appear to be simple, it has been found that very often operators find them troublesome and often require the assistance of a supervisor to reset and realign the attachments each time they are used.
  • the lining up of the attachments requires measuring devices and the securing of the attachments requires special screws, lever and other types of tools. Therefore, such lining up and securing operations are time consuming and lower overall production eificiency.
  • sewing machine attachment means for attachinent to the bed plate of a sewing machine comprising a throat plate having a needle hole and accommodating aperture means formed therein, and guide I tis another object of this aspect of the invention to provide a material guide which does not require a measuring device for setting different seam widths.
  • a material guide for attachment to the bed plate of a sewing machine.
  • the material guide comprises a throat plate having a conventional needle hole.
  • a plurality of pairs of accommodating means are disposed in the throat plate.
  • the pairs of accommodating means are parallel to each other and spaced at different distances from the needle hole.
  • an edge guide means having at least one guide edge and a base.
  • a pair of engaging means extends from the base to engage one of the pairs of accommodating means in the throat plate.
  • Another feature of this aspect of the invention is the incorporation of a magnet in the edge guide means so that it is a simple matter to attach it to the outer iron casing of the sewing machine when not in use. Therefore, the guide means is readily available and the operator does not have to grope through her parts drawer to find it.
  • a removable attachment holder apparatus for a sewing machine which includes a throat plate having a plurality of apertures.
  • An attachment-holding means is further provided having engaging means extending from its base for locking accommodation with the plurality of apertures in the throat plate.
  • Means on the attachment holding means are provided to anchor an attachment to a sewing machine.
  • a feature of the attachment-holding means is the provision of a handle and a handle holder means.
  • the handle supports a sewing machine attachment and the handle holder means is lockingly accommodated by the throat plate.
  • a keyed dovetail engagement is provided between the handle and the handle holder means to prevent the movements of the handle.

  • Figure 10 is a side view of the handle of Figure 9;
  • Figure 11 shows a bottom view of the handle of Figure 9.
  • Figure 12 is a sectional view taken along the line 12-12 of Figure 9.
  • a material guide 10 having edge guide means 12 and throat plate 14 is shown disposed in the conventional bedplate 16 of a sewing machine.
  • the throat plate 14 as shown in Figure 2, has a conventional needle aperture or hole 18 and a conventional feed dog opening 20.
  • Conventional guide lines 21A to 21N with fractional markings are disposed in the throat plate 14 for indicating spacing from the guide lines 21A to 21N to the center of the needle aperture 18.
  • Disposed in the throat plate 14 are a plurality of equispaced pairs of accommodating means or apertures 22A and 23A and B, and 24A and B.
  • the pairs of apertures 22A and B to 24A and B are parallel to each other and are at predetermined distances from the needle aperture 18.
  • a line joining the centers of apertures 22A and 22B is parallel to a line joining the centers of apertures 23A and 23B which is parallel to a line joining the centers of apertures 24A and 243.
  • Each of the pairs of apertures is at a predetermined distance from the needle aperture 18.
  • the spacing from the needle aperture 18 is determined by considering the width of the edge guide means 12 (Fig. 1). For example, when the edge guide means 12 is accommodated by the apertures 22A and 22B as is hereinafter fully described, the distance between the side 26 of the edge guide means 12 and the needle aperture 18 is, for example, one-quarter inch. Thus, with the edge guide means 12 in this position, the mate? rial guide means 10 will permit the sewing of one-quarter inch seams.
  • the spacing between the aperture 22A and 23A may also be one-quarter inch and similarly the spacing between the aperture 23A and the aperture 24A may also be one-quarter inch. Therefore, by engaging the edge guide means 12 in one of the plurality of apertures it is possible to provide a guide for seams differing in one-quarter inch increments.
  • Throat plate 14 is also provided with holes 27A and 27B which accept screws 29A and 29B for securing the throat plate 14 to the bedplate 16.
  • Figures 3 and 4 show the edge guide means 12 in greater detail.
  • the guide means 12 has a pair of parallel sides 26 and 28.
  • Extending from the base 30 of the edge guide means 12 are a pair of engaging means or studs 32 and 34. Studs 32' and 34 are spaced from each other and so shaped to "register with the apertures 22A and'22B to 24A and 24B of the throat plate of Figure 2.
  • FIG. 5 shows various embodiments of a typical stud 32A which may be employed with a corresponding aperture 22.
  • studs 32 and 34 are of resilient material and are provided with respective lateral projections 36 and 38.
  • the outside diameter of the lateral projections 36 and 38 is slightly greater than the inside diameter of the apertures 22A and 223 to 24A and 24B, to provide a locking accommodation of the studs 32 and 34 by the apertures 22A and 228, for example.
  • Recesses 39 and 40 are disposed in the ends of the edge guide means 12 to facilitate grasping it when the edge guide means 12 is to be removed.
  • the studs 32 and 34 are positioned closer to the side 26 than the side 28 (see Figure 4).
  • the spacing from one of the sides of the edge guide means 12 to the needle aperture 18 is different than the spacing from the other side of the edge guide means 12 to the needle aperture 18 when the edge guide means 12 is reversed degrees in the same pair of apertures.
  • a wider seam may be sewn than when the side 28 is nearer the needle aperture 18 when using the same pair of apertures (see Figure 1).
  • the number of possible seam widths is doubled.
  • the orientation of the studs 32 and 34 in the base 30 is such to permit seam width increments on one-eighth of an inch by re versing the side of the edge guide means in relation to the needle aperture 18 in the various pairs of apertures in the throat plate 14.
  • a knurled feeler 42 disposed near one end of the edge guide means 12 provides a simple indication as to which of the sides, 26 or 28, is closer to the needle aperture 18. For example, if the knurled feeler 42 is close to the operator, then the operator knows that the usable width increments are one-quarter, one-half, or three-quarters of an inch, and if the knurled feeler is positioned remote from the operator, the usable width increments are oneeighth, three-eighths, or five-eighths of an inch.
  • Another feature of this embodiment of the invention is a magnet 44 positioned in the top of the edge guide means 12.
  • FIG 6 shows a removable attachment-holder 50 in accordance with another embodiment of the invention.
  • the removable attachment-holder 50 comprises the throat plate 14 which lockingly engages the holder plate 52 to which is secured a handle 54 which carries a conventional sewing machine attachment such as the hemmer 56.
  • the throat plate 14 is identical to the throat plate 14 of Figures 1 and 2.
  • the holder plate 52 as shown in Figure 7, is a substantially T-shaped member. Studs 58, 59, 60 and 61, which are similar to the studs 32 and 34 of the edge guide 12 of Figure 3, extend from the bottom face of the crossbar portion 65 of the holder plate 52.
  • Studs 58 to 61 are oriented to register with two pairs of the apertures 22A and 22B to 24A and 24B, of the throat plate 14 as shown in Figure 2.
  • holder plate 52 may be rapidly and easily secured to, or removed from engagement with the throat plate 14.
  • the stem portion 67 of holder plate 52 is shaped to be the tenon of a dovetail joint (see Fig. 8).
  • the hole 64 which is countersunk square shaped accommodates a square-head screw 63 which cooperates with nut 74 to secure a sewing machine attachment as is hereinafter more fully described.
  • the combination of the holder plate 52 and the throat plate 14 as shown in Figure 6, may be used to hold conventional sewing machine attachments. However, as shown in Figure 6, this combination is used to support the handle 54 which carries a conventional sewing machine attachment such as the hemmer 56.
  • Handle 54 is substantially an L-shaped member with a slot 66 in the base portion 68 of the L. Slot 66 is provided to accommodate the screw 63 which is accepted by hole 64 of the holder plate 52 ( Figures 6, 7 and 8).
  • a pair of holes 70 and 72 countersunk square-shaped to accept square-head screws in the handle 54 permit the securing of the conventional sewing machine attachment such as hemmer 56 to the handle 54
  • the bottom face of base portion 68 of the handle 54 in the region of the slot 66 has a dovetail groove 69 acting as the mortise for the dovetailed tenon of the stem portion 67 of the holder plate 52.
  • the dovetail joint is so constructed to provide a continuous surface along the bottom face of handle 54 and and the top face of holder plate 52. Thus, handle surface 79 will be flush with the bed plate 16 of the sewing machine.
  • Holder plate 52 is lockingly engaged by positioning the studs 58 to 61 over the appropriate apertures 22A and 22B to 24A and 24B and by applying a slight downward pressure.
  • Handle 54 carrying the appropriate attachment such as hemmer 56 is secured to holder plate 52 by sliding dovetail groove 69 over the stem portion 67.
  • nut 74 is tightened on screw 63 to firmly anchor handle 54 to holder'plate 52. .Thus, the hemmer 56 is properly positioned and ready for use.
