BINDER FORI SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 669,806, dated March l2, 1901.

Application filed November 16| 1900. b'erial No. 36,728. (No model.)

T0 all whom. it may concern,.-

Beit known that we, WALTER C. RATHBUN and FRANK B. RATHBUN, of Utica, in the county of Oneida and State of New York,have invented certain new and useful Improvements in Binders for Sewing-Machines; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accom panying drawings, and to the reference characters marked thereon, which form part of this specification.

Our invention has for its object an improvement in the combination of binders for sewing-machines, which are particularly adapted.

4L shows a plan View of the edge-guide consti-- tuting a portion of the mechanism. Fig. 5 shows an edge view of the same. Fig. 6 shows a plan view of the lower port-ion of the binder attachment, together with the device shown in Fig. 4 applied in position as shown in dotted outline. Fig. 7 shows a perspective view from the under side of the upper portion of the binder. Fig. 8 shows a cross-section of the work performed by the combination of binders.

Referring' to the reference letters and iigures in a more particular description of the device, A indicates the upper binder, which is secured on a plate-like base 2, and the same is mounted on the presser-foot stem 3 of the sewing-machine by the jointed construction shown in Figs. 2 and -that is to say, the presser-foot stem is provided with a foot-like portion, as indicated, which is received between a pair of projecting earsAA on the plate 2. Passing through the ears and the foot of the stem 3 is a pin 5, on which the plate 2 has a limited swinging movement. A spring 6 is interposed between the heel of the foot of the stem 3 and the plate 2, whereby the forward end of the binder A is thrown upward when the presser-foot is raised. The binder A is adapted to receive a strip of raw-edged binding, as d, at the opening 7 in the end of the binder, and the goods in passing through are, by means of the curved inwardly-turned converging portions 8 8 and the tongue-like portion 9 of the binder, folded inwardly, and are presented at the edge of the plate 2 in the shape of the strip, with the edges turned inwardly, as will be readilyT understood from Fig. 8, and with the edges so disposed that they will pass under the needle-openings 10 10 in the plate 2.

The lower portion ofthe binder-B is secured to the base of the machine and is provided at one end with an opening 1l, adapted to receive the strip of raw-edge binding, as b in Fig. 8, and by means of the inwardly turning and converging portions 12 l2 of this binder and the central tongue portion 13 the edges of the binding are drawn over or folded, as will be readily understood from Fig. S, and are presented at the end of the binder B in a position coinciding with the strip of binding passing through the binder A and adapted to have the stitching take place in the folded edges, as indicated in Fig. 8. In the top of the binder B there is provided a slotted opening through which a pick may be inserted for th reading the binding throughthe binder. A similar coinciding opening is also' made in the base portion of the tongue 13. The top of the binder B is closed, and thereon is mounted the edge-guide C, preferably of the angular form shown and having the vertical guiding-face 14. The guide Cis mounted on a shank or arm portion 15, which is secured to the frame of the machine by the set-screw 16. This screw may also secure the portion B of the device. The strip of goods for the lower binder Bis preferably received through a slotted opening in the table or frame, as indicated at 17, and the strip is held in extended position and some tension placed upon it by means of the plate 18, which is pivoted at 19 in fixed bearings, and the pressure is applied to the plate 18 by means of aspring 20.

As previously stated, this construction is particularly adapted for placing waistbands on overalls, and the strip of binding which passes through the lower binder B is preferably a continuous strip, while the binding passing through the upper binder A is pref- IOO 'erably of suitable lengths for the purpose. The binding-strips being threaded into the binders and the parts in readiness for operation, the edge or body of thegarment is brought into engagement with the guide C and particularly the vertical face 14 thereof. The sewing-machine then being operated, the three pieces are passed simultaneously under the needles, whereby the needle n forms the line of stitches (indicated bys in Fig. 8) passing through the inwardlyturned folded edges of the pieces a and b and through the garment. The needle n/ forms the row-of stitches 8, passing only through the folded or inwardly-turned edges of the bindings aand b.

It will be noted that the end of the tongue portion 13 of the lower binder is allowed to approach the positions of the needles as near as possible and that the plate-like portion 2 of the binder A, in connection with the tongue portion 13 of the lower binder, serves to hold and maintain the inwardlyturned edges of the bindings from the time they leave the turning and folding mechanism until they are stitched.

By means of the construction herein described We are enabled to cheaply and economically produce a binding for overalls that is strong and neatly and perfectly applied to the garment.

We do not wish to be understood that the device is only adapted or claimed for use in connection with overall-work, but is, perhaps, equally adapted for numerous other uses.

What we claim as new, and desire to secure by Letters Patent, is-

1. Thel combination in a sewing-machine binding mechanism, of a lower stationary double-edge folder, an upper movable doubleedge folder having two needle-openings located adjacent to the edges of the upper folder, and an intermediate edge-guide, substantially as set forth.

2. Inasewing-machinebindingattachment the combination of the upper binder A adapted to turn the opposite edges of a strip of binding and mounted on the plate-like portion 2 adapted to press and hold the folded edges of the binding,the lower folder B adapted to turn the edges of a binding, and the intermediate edge-guide for the goods, substantially as set forth.

3. The combination with a double-needle sewing-machine of the upper binder A adapted to fold the opposite edges of a strip of binding mounted on the plate-like base 2 having needle-openings adjacent to the delivery end of the binder, the lower binder B adapted to fold the edges of a strip of binding having its delivery end arranged under the plate 2 of the upper binder, substantially as set forth.

4. In a sewing-machine binding mechanism, the combination of an upper binder mounted on the presser-foot arranged to fold each edge of the binding-strip downwardly and inwardly, a lower folder adapted to fold both edges of its strip inwardly and upwardly, and the edge-guide arranged between the upper and lower binders, substantially as set forth.

In witness whereof we have affixed our signatures, in presence of two witnesses, this 12th day of November, 1900.
