T 0 all whom it may concern.

Be it known that I, Jonn E. CHALMAN, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certainnew and useful Improvements in Binders for Sewing- Machines, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

The invention relates to new and useful improvements in binders for sewing machines, and more particularly to a binder which is adapted to invert the binding strip as it is led to the stitching mechanism, and known in the art as an English binder.

Binding strips are often previously folded before they are passed into the binder, and then formed into rolls. These folded strips do not run in uniform widths. An object of the present invention is to provide a binder having means which may be quickly ad- 7 justed so as to adapt the binder for strips of slightly varying widths.

It is sometimes desirable to stitch the binding strip to the fabric so that one face of the fabric will be overlapped to a greater IIII tit

extent than the other, and a further object of the invention is to provide a binder which may be quickly adjusted so that the binding strip as it is inverted may be directed to the fabric being bound in such a manner that one face of the fabric will be overlapped to a greater extent than the other.

These and other objects will in part'be obvious and will in part be hereinafter more fully disclosed.

In the drawings, which show by way of illustration one embodiment of the invention:-

Figure 1 is a plan view showing a portion of the cloth plate of a sewing machine having my improved binder attached thereto, and the position of the binder relative to the needle of a stitching mechanism;

Fig. 2 is a sectional view through the binder on the line 2-2 of Fig. 1;

Fig. 3 is a perspective view showing the binder with the guides detached;

Fig. t is a front view of a portion of the binder with the guides adjusted for positioning the edges of the binding strip so that the fabric is overlapped to the same extent on both faces thereof;

Fig. 5 is a similar view, but showing the wall 9. The turned-down li guides adjusted so that the binding strip W111 overlap the fabric to a greater extent on the under face thereof;

Fig. 6 is a detail, showing in section a strip of fabric with the folded binding strip attached thereto; and

Fig. 7 is a detail showing a small section of the folded binding strip as it is rolled. he improved binder is shown applied in Fig 1 of the drawings to a sewing machine having a work support 1, the binder indicated at 2 being secured to a bracket 3 by clamping screws 4l4. The needle of the sewln machine is indicated at 5, and the direction of feed is indicated by the arrow in this figure. i

til

The improved binder consists of a body portion 6 which has a recess or guiding slot 7 extending from end to end'thereof. The outer face of the binder is slotted at 8 to facilitate the insertion of the binding strip through the binder. At the delivery end of the hinder the recess or guiding slot is shaped so as to form substantially U-shaped guidlng walls 9 and 10, one ofwhich is located within the other, see Fig. 3. The extreme edge of the inner guiding wall 9 lies in a plane which is substantially at forty-five degrees to the line of feed and to the longitudinal axis of the binder. The bindin strip is led through the, binding slot 7 an is lnverted over the extreme edge of the this guiding finger .and into threaded openings 17--17 in the body of the binder. The gulding finger 14: is turned down at its extreme end, as at 18. This end 18 of the guiding finger lies in front of the cut-away portion 12 and extends substantially to the of the finger is wide and will cross the incllned end of the guiding wall 9 in all positions of adjustment and serves as a guide for the upper ed e of the bindin strlp.

t the lower si e of the binder there is also a guiding finger 19 which is secured to the binder by screws 20 passing through ict lllltt elongated slots 21 in this guiding finger 19 and into the body of the binder. This guiding finger has an upwardly turned lip or end 22 which extends into the cut-away portion indicated at 13 and to a point close to the under face of the guiding wall 9. This turned-up lip 22 extends across the inclined end of the guiding wall 9 .and serves as a guide for the under edge of the binding strip.

It will be apparent that these guidin fingers 14 and 19 may beindependently a justed. If they are set so that their ends 18 and 22 are in the same vertical plane, then the guiding strip as it leaves the binder will be guided to the fabric so that the opposite faces of the material will be overlapped to the same extent.

In Fig. 6 of the drawings, I have shown a fabric F having my folded binding strip indicated at B applied thereto. This binding strip is folded previously to being passed to the binder, as indicated in Fig. 7 of the drawings, where the in-turned edges are shown at Z) and b. The folded binding strips vary somewhat as to width. The bindermay be quickly adjusted to accommodate these varying widths by loosening the screws 15 and 20 and shifting the guide fingers. When it is desired to overlap one face of the fabric to a greater extent than the other by the binding strip, then one guiding finger is shifted in or out relative to the other. In Fig. 5 of the drawings, I have shown the guiding fingers shifted so that the upper edge of the binding strip will overlap the fabric to a less extent than the lower edge of the binding strip.

It is obvious that minor changes in the details of construction and the arrangement of parts may be made without departing from the spirit of this invention, as set forth in the appended claims.

Having thus described the invention, what is claimed as new is 2-- 1. A binder including in combination a body portion having a guiding slot for folding a binding strip, the delivery end of said binder having inclined edges disposed so as to invert said binding strip as it is led to the stitching mechanism and guiding fingers adjustable longitudinally of the binder, said guiding fingers having wide ends positioned so as to cross the inclined edges in all adjusted positions, whereby the binding strip will be engaged and the respective edges thereof guided at its inverting point.

2. A binder including in combination a body portion having a guiding slot for a folded binding strip, said body portion at its delivery end having U-shaped guiding walls, the inner wall being cut at an angle to the longitudinal axis of the binder so that said strip may be inverted as it is led to the stitching mechanism, the upper wall of said binder being cut away adjacent the delivery end thereof, and guiding fingers carried by the binder and adjustable longitudinally thereof, each guiding finger having its end bent so as to extend to a point adjacent the inner guiding wall .and serve as a guide for the respective edges of the binding strip.

In testimony whereof I aflix my si nature.
