SEWING-MACH Application filed September This invention relates to binder attachments for sewing machines of the kind in which a strip of material is folded and fed 1n a direction at right angles to its initial direction of feed and in which the raw edges of the bindng strip are folded over in readiness to be stitched to the material to be bound, whereby the necessity of first preparing the binding strip with its edges turned and pressed down is avoided.

Binders of this character have heretofore been proposed in which a base plate is removably secured, with capacity for adjustment, to the bed plate of the machine and supports the binder attachment which embodies a folding plate formed with an axial rib merging into a flat receiving space and having flanges formed with inwardly turned lips or wings to enclose a guide tongue cooperating with the plate whereby the binding strip may receive a W-shaped cross-section. At the extreme delivery end of the plate the flanges have been formed with inwardly and rearwardly extending tongues which extend across the adjacent end edge of the guide tongue. Such a folding plate as heretofore used has, of n cessity, been formed of such relatively thick sheet metal, in order that it may hold its shape in use, that it has not been possible to give the plate the requisite compound curvature to properly fold a binding strip with the greatest efficacy, especially if the strip is of a soft material; and wire and loops have also been provided on the delivery end of the flanges to form inwardly projecting edges therefor which are not durable and involve a manual operation which has been found difficult, requires considerable time and generally results in an unsymmetrical formation, no two wires being alike when aflixed.

The present invention seeks to avoid the impractical features hcreinbefore discussed by the provision of an outer shell member of simple construction but of sufficient strength to adequately reenforce, when assembled therewith, a folding plate formed of sutiiciently thin material that it can be given the requisite curvature. This shell member also has formed thereon, by a die, in a stamping operation small fingers bent on the delivery end which, when the device is assembled, lie in spaced relation with the ends of the forming plate and guide tongue. The flanges are bevelled at the delivery end and recede from the fingers with a gentle curvature to form what is in effect channels or guides from the INE BINDER.

grooves in the folding plate to the notch therein from whence the folded material is directed at right angles to its previous direction of travel. With the construction just described it is possible to adjust the tape backwardly in case of non-sewing.

Heretofore the base plate which supports the binder has been removably and adjustably secured to the bed plate of the machine by screws or the like and by such construction the adjustment of the guide with respect to the needle has involved considerable skill, time and labor as well as necessitating the use of tools. The present invention seeks to provide a liner adjustment of the guide with respect to the needle by what may be termed a micrometer adjustment wherein no tools are required. More particularly, the adjusting devices take the form of a pivoted lever operatively connected to the base plate eccent-rically of the pivot whereby movement of the lever about its pivot will cause movement of the base plate to or away from the needle in a lesser degree, obviously, than the movement of the lover.

The invention also has to do with a convenient method of mounting the reel from which the tape is supplied to the binder in conjunction with the binder attachment whereby both binder and reel may be handled as a unit. To this end the reel is carried upon the extremity of the adjusting lever or an extension thereof.

The invention further has for its object to provide a binder attachment which shall be practical from the standpoint of convenience, ease and cheapness in manufacture and durability in use. To this end the component ele ments of the binder are formed of stampings which may be soldered together to form an operative whole.

These and other objects of the invention and the means for their attainment will be more apparent from the following detailed description of a preferred embodiment thereof which is illustrated in the accompanying dra ings and in which:

Figure 11 is a view looking from above in Figure 10 and showing the clip of that figure.

Referring to Figures 1 and 2 the bed plate 1, of a sewing machine is adapted to be secured thereto in any convenient manner as by screws iass ng through the apertures 2. The bed plate 1 is also provided with customary aj'iertures 3 and 4 as will be understood and an eye 5 for a needle. A presser foot is indicate'cl in broken lines at 6. A base plate 7 having an upright bracket plate 8 along its edge is ordinarily secured as by a or the like to the bed plate 1. In the illustrated embodiment the bed plate is formed with a groove 9 adapted to receive a flange 10 formed on the rear or lower face of the base plate 7. The base plate 7 is also formed with an elongated aperture 11 having a recess 12 at one side thereof. Immediately above th 1* base plate there is disclosed a lever 13 pivo ally mounted upon the bed plate 1 by a screw 14 passing through the elongated aperture 11 in the base plate and threaded into a hole 15 in the bed plate of the machine. The lever also carries on its underside a lug l6 ent ring the recess 12. This lug is eccentric with respect to the pivot 14 whereby movement of the lever 13 about its pivot will cause movement of the base plate 7 with respect to the groove 9 thereby moving the base plate n arer or further away from the needle eve 5.

Carried upon the projecting bracket plate 8 is the folding device or hinder according to the present invention. The folder is formed of a plurality of component elements illustrated in Figure l throu trh ll. Directly eecured as by soldering or the like to the upright bracket plate 8 is an outer shell member indicated as a whole at 17 having a plain rear surface 18 turned slightly outwardly and rearwardly at the receiving end as at 19. At the delivery end the shell member is formed with a notch 20 and adjacent the delivery end are carried flanges 21 rounding gently outward and provided respectively with inwardly directed tongues 22. The delivery end of the flanges are bevelled from the tongues 22 to the sides of the notch 20 and terminate in fingers 23 extending into the notch portion in substantially the plane of the rear surface 18.

The folding plate shown at Figures 6 and 7 is indicated as a whole at 24. It is formed of very thin sheet metal by dies so that it may be given the proper gradations of curvature to permit it to fold even the softest of materials in a perfect manner. It is because of the light material of which it is formed that the shell member is utilized to give adequate strength and rigidity to the folding plate after it is formed. The folding plate is formed at the receiving end with a substantially flat receiving face 25 having an outwrrdly and rearwardly deflected flange 26 which, when the folding plate is assembled upon the outer shell member adapted to overlie and engage the end 19 of that member. he folding plate is formed with an axial rib 27 which merges into the receiving face 25 and is relatively high and narrow at the dclivery end and deeply notched as at 28. Adjacent the receiving end the folding plate is formed with side flanges 29 teri'ninating in wings 30 which. adjacent the receiving end, are substantially parallel with the receiving face 25 but which converge with respect to the flange 29 as the axial rib increases in height. At the delivery end the folding plate is also formed with flanges 31 which rise sharply from the axial rib to form acute angle grooves or troughs 32. The flanges 31 after diverging for an appreciable distance from the axial rib to form in general a W cross-section are turned inwardly and rearvardly as at 33, to serve as positioning means for a guide tongue hereinafter to be c escribed. Closing the notch formed by the rib 27 at the delivery end is a U-shaped flange 34 perpendicular to the plane of the paper as viewed in Fig. 6 and shown clearly in Figure 7 as extending beyond the rear marginal face of the folding plate. This flange is adapted when the folding plate and outer shell member are in assembled relation to extend within the notch 20 of the shell member and with the flange 26 facilitate the positioning of the two elements.

The guide tongue 35 is illustrated in Figures 8 and 9 and is formed at the receiving end with a substantially flat face 36 and a start feed slot 37 midway between the ends. At the delivery end the tongue is notched as at 38 to cooperate with the notch 28 of the folding plate. The tongue is curved transversely to cooperate with the axial rib of the folding plate as will be understood. It is also formed with a bevelled receiving end shown clearly in Figure 9 at 39 which receiving end is adapted to lie closely adjacent the wings and to be held against said wings by means of the clip illustrated in Figures 10 and 11. Since the tongue and folding plate are both formed of very thin sheet metal in order that hey may assume the requisite curvature, the clip all) is availed of to secure the ends together and reenforce them with the aid of solder to produce a stilt construction at the receiving end. This clip is U-shaped in crosssection as shown in Figure 11 at 41 and be tween the arms of the U-shaped portion are adapted to be received the ends 36 and wings 30. Side elements 42 are formed at the ends of the U-shaped portion to overlie and reenforce the side flanges of the folding plate as will be understood from an inspection of Figures 1 and 2. p

in the assembly of the device the folding plate and guide tongue may be first assembled, the wings 30 and serving to pos. on the tongue with respect to the axial rib. The

tongue may then be secured to the folding plate by the clip l0 and solder may also be availed of to further secure the two in operative position. The outer shell member and folding plate may then be assembled with the flange 26 overlying the edge 19 of the shell member and the flange extcndii within the notch 20, the tongues 22 overlying the wings 323 with the bevelled edges of the flanges 21 in spaced relation with respect to the delivery end of he folding plate. After the component elements of the device have been suitably secured together the rear face of the outer shell member is secured to the front face of the upright bracket member carried iih the base plate as clearly shown in Figures l and 2.

As the folding device or binder is directly carried upon the base plate and the base plate is capable of adjustment \Vlkll respect to the needle eye 5 it follows that the binder is thus readily adjustable with respect to the needle eye without necessitating the use of a screw driver or other tool in the making of the adjustn'ient.

Referring again to Figures 1 and 2 it will be observed that the lever 13 is fo aned with an extension 43 carrying a pin i l at its extremity upon which is adapted to turn a reel 45 carrying the binding tape 46.

It will thus be seen that a binder attachment has been provided which is practical from the standpoint of manufacture and use. The construction provides for a guidanre of the tape which facilitates its adjustment in a reverse direction in case of failure of the sewing device to properly secure the tape to the material to be bound. Exact adjustment of the binder with respect to the needle is also possible with the device according to the present invention in a simple, convenient and expeditious manner, while the reel carrying the tape is so mounted as to be a part of the attachment and capable of removal with the binding attachment as a unit.

It is to be understood that the various features hereinbefore enumerated are capable of independent use although mutually eontributing to the desired end and no limitation is intended in the configuration and assembly according to the foregoing description and illustrations except as indicated in the accompanying claims.

Having thus described my invention I claim 1.
