ALBERT RON'I'KE, OF BRIDGEPOR'I, CONNECTICUT, ASSIGNOB, TO THE SINGER MANU- FACTURING COMPANY, A CORPORATION OF NEW JERSEY.

GUIDE FOR SEW INGr-MAGHINES.

Specification of Letters Patent.

Patented Apr. 16, 1912.

To all whom it may concern:

Be it known that I, ALBERT RONTKE, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Guides for Sewing-Machines, of which the following is a specification, reference being had therein to the accompanying drawings:

This invention relates to improvements in edge guides for sewing machines, and has to do particularly with the class of devices used in connection with the stitching of mens linen collars.

The primary object of the invention is to provide improved means for edge stitching and securing the collar band to the turned down or body portion of the collar, and to this end edge guides having adjustments in transverse planes are provided, thus permitting the use of a permanently secured under edge guide and an upper guide which is maintained in the same plane as the permanently secured edge guide, whether for edge stitching or band attaching.

In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure 1 is a view in perspective of the improved device, showing the guides adjusted to their positions for edge stitching. Fig. 2 is a view similar to Fig. 1, showing the guides adjusted to their positions for band attaching. Fig. 3 is a view in perspective of the base-plate, permanently secured edgeguide plate and the stop for registering the adjustably mounted intermediate edge-guide and fabric separator. Fig. 4 is a detail perspective view of the slide or carrier upon which the intermediate edgeguide and fabric separator is adjust-ably mounted. Fig. 5 is a detail perspective view of the intermediate edge-guide and fabric separator.

1 represents the base-plate of the attachment which is secured in any suitable manner to the bed-plate of a sewing machine, 2 the stationary edge guide plate provided with the edge-guide 3 and secured by

screws

4 and 5, 5 to the base-plate 1. A yieldingly mounted overhanging edge guide 6 is provided with a guide carrier 7, the latter secured at its rear end (in the present instance, by brazing) to a spring metal plate tively.

8 which in turn is secured by the

screws

5, 5 to the upper side of the plate 2, said guides 3 and 6 comprising a two-part edge-guide.

9 represents the intermediate edge-guide and fabric separator provided with the edge-guide 10 and cam portion 11, said edge guide and fabric separator being adjustably secured by screws 12 to the forward end of a carrier 13 which is mounted to slide in a groove 14: formed in the base-plate 1 and frictionally held against accident-a1 movement by the screw 15, washer 16 and spring 17, in acommon manner.

18 represents a stop adjustably secured by screws 19 to the base-plate 1, said stop acting to arrest the backward movement of the carrier 13, the limit of movement of said carrier in the opposite direction being governed by the screw 15 contacting with the wall 20 of the slot 21 formed in the baseplate 1. i

In the operation of the device, supposing it -to be employed in connectionwith the stitching of collars, the carrier 13 is first adjusted to the position shown in Fig. 1, thus causing the several guides to effect a single edge-guide against which the collar band is guided while its free edge and when the stitching operation has reached the point at which the unstitched edge of the body or turned down portion of the collar is to be inserted, the intermediate ide 9 is adjusted to the position shown 1n Fig. 2, with its free end inserted between the plies comprising the collar band, the edges of the upper and lower plies of the band being guided by the edge guides 6 and 3, respec- At this point in the operation the body portion of the collar is positioned in the slot 22 with its unstitched edge in contact with the edge-guide 10, the adjustment of the guide 9 through the cam portion 11 having raised the edge-guide 6 sufliciently to allow said body portion to pass between the guides 3 and 6. At the completion of the stitching of the body portion of the collar to the band, the intermediate guide is withdrawn to its first mentioned position and the seam completed, said seam including sufficient of the free edge seam of the band to permit of the adjustment of the guide 9 after it has passed out of guiding relationship with said body portion.

is being stitched,-
