To all whom it may concern:

Be it known that we, JOHN F. BERGEN, a citizen of the Republic of Lithuania,,'residing in Brookl n, in the county of-Kings and State of Nzw York, and JACOB Mmoos, a citizen of the Re ublic of Poland, residing in Brookl n, in t e county of Kings an State of ew York, have invented certain new and useful Improvements in Binder Attachments for Sewing-Machines, of which the following is a s cification. This invention re ates to improvements in binders of the type usually designated as combination right angle binders, by means of which the strip of material is folded and fed in a direction atright angles to its ini- An object of the invention is the provision of an improved binder of the character described, simple in construction, inexpensive to manufacture and effective and durable in use to accomplish the purposes set forth.

Other objects of the invention are to simplify the construction of the binder and to provide 'a removable guide-tongue for facilitating the starting of the binding'strip, and simplifying the construction of the device and making more economical its manufacture.

Other objects of the invention will appear as the description roceeds, and while herein minute details of the invention are disclosed, the invention is not limited to these, since many and various changes may be made without departing from the scope of the invention as claimed.

In the accompanying drawings showing by way of example one of many possible embodiments, of the invention,

Figure l is a'front elevation of the binder.

Fig. 2 is a bottom view;

Fig. 3 is an end view;

Fig. 4 shows a section taken on the line 4-4 of Fig. 2, parts being omitted;

Fi 5 is a perspective view of the tongue, the ront face thereof being shown uppermost;

Fig. 6 is a perspective view showin the rear face thereof uppermost Figi is a perspective view of the main folding plate of the binder and its support,

tiall flat rearwardly tial' direction of feed, and inwhich the raw of the tongue the open front face being shown uppermost, the guide-tongue being removed;

Fig. 8 shows a section on the line 8-8 of F 1g. 1 and Fig. 9 is a fragmental pers ectilvei' view of the delivery end of the fol ing p a e.

Abase plate 10 formed with an upright bracket plate 11 on its front edge. A folding late 12 is'secured on the forward face of said bracket plate 11 approximately in they plane thereof and formed at its receivin end with a substaneveled receiving face (shown in bottom plan in 1 Fig. 2) is mounted on the machine bed and 14 Fig. 7) substantially the width of the bindin strip 15, (Figs. 1 and 2). The front face ,0 saidfolding plate is formed with an axial rib 16, highest and narrowest and deeply notched, as at 17, (Fig. 9) at its del1very end, and gradually merging into said receiving face 14. Said late 12,-. is also formed with converging sid e flanges 18 extendlng from end to end of the side edges of the folding plate and cooperating with said r1b to form grooves or troughs 20 (Fig. 4). Sa1d plate 12 is provided near its ends with inwardly and rearwardly folded deliveryend lips 21 (Fig. 7) and receiving-end lips 22 extending to near the ribs 16,;the receiving-end lips 22 bein bent to be nested in and slightl spaced rom said troughs 20.

Wire-end loops 25- (Figs. 7 and 9) are provided on the delivery end of said flanges thereby to form inwardly projecting edges for the delivery end of the flan es.

A friction uide-tongue 27 ig. 5) frontwardly beve ed at the receiving end as at 28 and deeply notched as at 29 at the delivery end is disposed within the folding plate (Fig. 1) conforming approximately to the shape of said rib 16 and contacted by and held near said rib by said

lips

21 and 22. Said tongue is axially slotted to provide a start-feed slot 30 for starting the feeding of the binding strip.

Said tongue is rovided at its receiving end with outwar ly, backwardly and inwardly curved side wings 32 (Figs. 5 and 6) received between said flanges 18 and under the receiving-end lips 22 to form with said flat face 14 an approximately rectangular vertical throat 33 (Fig. 8) merging into an approximately W-shaped passage at said receiving-end lips 22.

Before starting the feeding of the strip, the tongue 27 is removed by drawing it out 55 in operative holding position by material from under the

lips

21 and 22. Ihe end of the strip is then placed in the folding plate, and the tongue replaced. A pin or the like may be thrust through the slot 30 to force the strip along until it is in position. to feed properly.

In the operation, the binding strip 15, with I its .raw edges, is passed in the direction of the ing up the middle of the strip, while the part about half way between the middle arrow of Fig. 1', into the throat 33 at the delivery end thereof, whereupon the strip is convexed frontwardl centrally )of its width by reason offthe rontwardly curved rib 16. At the same time the edges of thestrip are turned up by the flanges 18 as the latter converge. ,As the stip further'passes into the folding plate, the strip receives a W-shaped cross section, the raw edges of the strip contacting the lips 21,the rib 16 holdthe top and bottom of the work 35 (Fig. 2)

which is fed across the bed plate of the machine in the direction of the arrow of Eig. 2, in the usual manner, the usual feeding 85 mechanism of the machine drawing the work,

together with the facing or binding strip 15 under the presser o manner. p

The binding strip '15 is, during its movement in one direction, folded with its raw edges turned over away from each other, but that subsequently the bindin strip is turned outside-in to bring these fol ed-in edges opposed to each other, one above the. other, with the strip in position to be folded over the edge'of the work 35 with one side thereof on top of the work and the other underneath thereof so that the necessity of first folding the edges of the strip before feeding the same to the folder is done away with.
