Specification of Letters Patent.

Patented Jan. 16, 1917.

T 0 all whom it may concern Be it known that I, PHILIP TOMANEK, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Binders, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention has for its object to provide a sewing machine binder of which the scroll-guide is formed in two yieldingly connected sections which can readily adjust themselves to varying thicknesses of work or to cross seams therein. This has been accomplished, in the preferred form of the present improvement, by the provision of two superposed scroll-guide sections whose delivery ends are held in yielding relation, the one being pivoted to the other and main tained in operative relation therewith by means of a spring carried by the pivotal pin. In order to insure a positive alinement of the superposed scroll-guide sections, the support for the one is provided with an aperture adapted to receive a guide-arm carried by the other. Near the receiving end of the scroll-guide sections there is provided a vertical edge-guide which insures the proper presentation of the material to the bindertape and prevents it from displacing the latter within the scrollguide.

In the accompanying drawings Figure 1 is a perspective view of the binder,'Fig. 2 is a side elevation thereof, Fig. 3 is an end elevation of the binder, Figs. 4 and 5 are per spective views of the lower scroll-guide section and supporting plate, Fig. 6 is a perspective view of the upper scrollguide section with its depending guide-arm and threaded pivotal pin, and Fig. 7 is a detail view of the nut for the pivotal-pin of the upper scroll-guide section.

As represented herein, the binder is mounted on a base 1 having the usual slot 2 for a fastening screw for rigidly securing the same to a sewing machine bed-plate. The base is provided with an upturned lip 3 which is apertured at 4 to receive the hold ing screws 5 entering the carrier-block 6 to which is rigidly secured, by soldering or otherwise, the lower scroll-guide section 7 The carrier-block 6 has a forwardly extending projection 8 which insures the proper guiding of the bodyfabric and binding to the stitch-forming mechanism. The loosening of the holding screws 5 permits adjustment of the carrier-block 6 and with it the lower scroll-guide section with respect to the stitch-forming mechanism in the direction of feed. In alinement with the inner guide tongue 9 of the lower scroll-guide section 7 is a fabric-supporting plate 10 which sustains the body fabric entering between the scroll-guide sections.

The lower scroll-guide section 7 has its portion 11 adjacent the receiving end apertured at 12 to receive a pivotal-pin 13 carried by the upper scroll-guide section 14. As will be observed, the pivotalor hingepin 18 projects from the outer convex face of the scroll-guide section 14 and is arranged crosswise of the binder-channel formed by the upper and lower scroll-guide sections. The pivotal-pin is screw-threaded to receive the nut 15 which has a reduced portion 16 forming an arbor for a coiled spring 17 having an arm 18 resting upon the top of the scroll-guide section 14, and another arm 18 resting against the end of the block 6. The upper scroll-guide section 14 is provided near the delivery end with a steady arm 19 adapted to enter the-guideaperture 20 in the carrier-block 6 to insure the proper register of the delivery ends of the scroll-guide sections, particularly when they are separated in passing cross-seams.

The binder, as thus described, obviously provides by means of the upper and lower overlapping members 9 and 14 a refiexly curved or U-shaped tape-guiding channel, laterally closed at the receiving end and gradually contracted from its receiving to its delivery end with overlapping members extending at the delivery end in the same direction from the intermediate portion or bottom of the channel crosswise of the length of the binder.

As represented in Fig. 3, the outer members of the scroll-guide sections 7 and 14 are overlapped to aiiord a continuous guiding wall for the convex face of the tape while the concave face of the tape is confined in position by means of the lips 21 and 22 extending, respectively, upwardly from the lower section 7 and downwardly from the upper section 14, being spaced from the overlapping walls of these sections to afford the tape-channel. These lips substantially close the channel at the receiving end and afford an edge-guide for the bodyfabric while an opening is provided between the said lips at the delivery end of the binder to enable the edge of the body-fabric to assume contact relation with the embracing binding-tape as they emerge from the binder to receive the stitching and to afford access to the channel for inserting the binding tape preparatory to a binding and stitching operation. The lips 21 and 22 also prevent the body-fabric from crowding the binding into either the upper or lower guide-channel and thus insure a uniform product with an equal amount of binding visible upon both the upper and the under side.

Adjustably attached to the base 1, by means of the fastening screw 23, is avertical tape-guide 24 through which the bindin is fed to the scroll-guides.

aving thus set forth the nature of the invention, what I claim herein is 1. A sewing machine binder composed of relatively movable sections together forming a U-shapcd channel, a hinge connection between said sections comprising a pivotal pin sustained by the outer convex face of one of said sections and disposed externally to and crosswise of said channel and in a line intermediate the overlapping walls thereof,

and a spring for maintaining said sections yieldingly in normal relation.

2. In a sewing machine binder, a baseplate, a scroll-guide comprising two yieldingly connected sections mounted thereon adjustably lengthwise of the binder, said sections together forming a tape-channel having overlapping members with closed outer extremities and having an opening between them communicating with the intermediate portion of the channel, a fabric-supporting plate rigidly attached to one of said sections, and an edge-guide affording a closure for said channel adjacent its receiving end.

3. In a sewing machine binder, in combination with a base-plate having a guide aperture, a scroll-guide comprising two pivotally connected sections of which one is mounted on said base-plate, a steady-arm arranged transversely to the pivotal connection and carried by the other of said sections and adapted to enter the guide-aperture of the base-plate, and means for maintaining said sections in yielding relation.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

PHILIP TOMANEK.
