This invention relates to a gauge foot for sewing machines.

It is an object of the present invention to provide a gauge foot which is adjustable and which will still be provided with a smoothing surface extending throughout the length of the gauge which .is offset from the sewing machine foot and wherein the gauge toot does not have to be completely disassembled from the sewing machine ioot in order to adapt the same for different widths.

It is another object of the present invention to provide an adjustable gauge foot or stitching gauge including smoothing elements or" different sizes or widths which may be severally or singularly assembled upon a bar which extends from the side of the sewing machine foot and retained thereon wherein simpl devices are provided for retaining the several smoothing elements upon the bar when located beside one another and in terlocking means for preventing relative rotation of the elements with respect to one another and for maintaining a flush and continuous bottom or smoothing surface.

Other objects of the present invention are to 7 provide an adjustable stitching gauge or gauge foot for sewing machines which is of simple construction, inexpensive to manufacture and efficient in operation.

For a better understanding of the invention, 1

reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. l is a perspective view of a sewing machine foot having means thereon for the attachment thereto and the securing thereof of my adjustable stitching gauge or gauge foot.

Fig. 2 is a collective and perspective View of my gauge foot detached from the sewing machine foot.

Fig. 3 is a transverse cross-sectional view taken across the sewing machine foot and looking in plan upon the top of my adjustable gauge foot with fragments of the gauge foot broken away to show the connection of one of the elements to the guiding plate at the end of the bar.

Fig. 4 is a perspective view of a sewing machine foot with my gauge foot secured thereto and extended to a maximum width and on which a plurality of smoothing elements have been mounted.

Fig. 5 is a fragmentary and top plan view of the end of my gauge foot on which a plurality of different size elements have been assembled and broken away to show the interconnection between the elements to retain them against movement 2 relative to one another when mounted upon the auge bar.

Fig. 6 is a top plan view of one of the elements.

Fig. '7 is aside elevational view of a modified form of element which can be attached to the g uge .oar without the removal of the bar from the sewing machine foot and wherein there is a spring clip means for retaining the element in the elevated position upon the bar.

Fig. 8 is a side elevational View of a modified form of gauge element and showing a difierent type of means for retaining the gauge element on the bar.

Referring now particularly to Figs. 1, 2 and 3, I5 represents a sewing machine foot through which a needle is extended to form a stitching It. This foot 5 has a spring member l! adapted to retain my gauge foot device it within a recess i9 the top of the foot.

, My gauge foot device includes a bar 2! adjustable through the recess l9 and on the gauging end of the same is a guide plate 22 adapted to run along the edge of a sheet of material 23 or along another stitching from-which the stitching H5 is to be gauged or governed. As shown in Fig. l a wide smoothing element 24 is mounted on the bar 2! and retained flush against'the guide plate 22. i his smoothing element 24 may be of variable width and will govern the distance to which the stitching l6 is to be applied to the sheet 23 from the edge thereof. This element has an opening 25 for receiving the bar 2 l. The element also has a projection 26 adapted to be extended into a hole 21 in guide plate 22 or in holes 28 of adjacent smoothing elements assembled on the bar as shown in Figs. 4 and 5. This hole and projection arrangement will retain the smoothing elements against vertical displacement from one another and to maintain a smooth and continuous bottom smoothing surface of the several smoothing elements on the bar 2 l.

Referring now particularly to Fig. 7, there is shown a modified form of smoothing element as indicated at 3! with a bottom smoothing surface 32. The smoothing element 3| has a top slot 33 adapted to receive the bar 2| when extended into the slot from the top edge of the element 3|. Into the opening 33 is a retaining element 34 which is backed up by a spring strip 34 secured along with the retaining element 34 to the top of the smoothing element 3| by a screw 36.

In Fig. 8, there is a modified form of smoothing element in which the opening or slot is extended into the rear end of the element as indicated at 31. The rear end of the slot 31 has diverging top and bottom faces adapted to receive a V-shaped portion 38 of a spring strip 39 secured to the top of the element by a screw 4|.

It will be apparent that there has been provided a gauge foot for sewing machines which is adjustable to diflerent widths by the utilization of different size smoothing elements and wherein the smoothing elements can be applied to the supporting bar of the foot without removing the bar from the sewing machine foot and wherein there is means provided on the several elements for retaining the same on the bar against displacement.
