Application filed April 2, 1910. Serial No. 552.947.

17 0 all LP/L07 it may concern Be it known that LFRAXK S. lVoonni-nm, a citizen of the United States. residing at Bridgeport, in the county of Fair-field and State of Connecticut, have invented certain new and useful Improvements in Guides for Sewing-Machines, of which the following is ment or article to be trimmed. and to this end the invention comprises multiple guiding elements arranged in such relationship that the seam-receiving edge of the trimming will be constantly held in contact with its edgeguiding element.

In the manufacture of certain classes of producti us it is frequently necessary to apply the trimmings in patterns of irregular design, which requires the manual manipulation of the article, thus making a ditlicult operation for an inexperienced operator; and when itis also necessary to mannally guide the trimming, the skill necessary to effect the required quantity and quality of production is attained only by long con tinued practice. The employment of the means herein disclosed is intended to materially lessen these (liiliculties and save a substantial portion of th time which the operator would otherwisen'eqnire to become proficient in handling the? work.

For some productions 'it is desirable to position the fabrics in abutting relationship and secure them by a line of zigzag stitchas are deemed necessary for a proper under standing of the application of the invention have been illustrated.

ing, while in other cases it is desirable to. overlap the edges of the. fabrics and secure' As the application oi the invention to the ()l'(1lIlt1l sewing machine foreilecting single lines of stitching -will be evident from an understanding of the present drawings, it has not been thought necessary to illustrate such form of machine. i

lel'erringto the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated, Figure .1 is a reduced perspective view of one form conunercidl zigzag or overseaming machine equipped with the improved mechanism. Fig? 2 is a full size plan view of the main guide shown in Fig. 1. Fig. 3 is a viewin elevation of the dclivery' end oi. the mainguide. Fig. dis a perspective view of the supplemental or bracket; arm guide. i I

having its seam edge arranged at an angle to the line of seam formation. 2 a bracket arm which carries at oncend the said baseplate and at its opposite end is frietionally secured by screw 3-and spring washer 4 .to a bracket the latter being adjnstably secured by a screw (5 to the bed-plate ot' thesewing machine, a stop 7 adjustably secured by screws 8 to the arm 2 acting to limit the swinging movements oi said base-plate in the direction-of the feed of the material.

9 represents an adjustable outer edgeguide secured by screws 10 to the seam edge of the base-plate 1. The base-plate 1 isprovided with vertirally-arranged brackets 11. 1), Hand l-t. the inner walls 25 and 96 of 'the braekets'll and '13 acting as edge-guides for the trimming strip. In the bracket 11 are secured the inner ends of the guide rods or guiding elements If) and 16 inclined at ditlerent angles from a horizontal plane. and in the bracket 13 is seeured'one end of the horizontally arranged guide rod or guid ing element 17, the opposite end of the latter rod being. secured in the bracket. 14 and the outer-ends of tlierods 15 and 16 being secured in the bracket 12. 6

To facilitate the delivery of the trimming from the supplv to the main guiding device. there is provided a suppltaiici'ital guide ltiadjustably secured bv screw 19 to the guide standard 20, which latter is secured by a suitable screw (not shown) to the upper surface of the sewing machine bracket arm as shown in Fig. 1, a supply spoolQl being suitably mounted on a rod 22 secured in a ,base 23, said base being conveniently positioned upon the commonly-employed sewing machine table or stand, at the rear of the sewing machine.

In the operation of the device, supposing it is desired to guide the adjoining edges of the materials in abutting relationship, the edge guide 9 ig adjusted to the position illustrated in the drawings where it acts to guide the edge of the material to which the trimming is to be applied. The trimming 2 is passed from the supply through the gu de 18, under the guide bar 17, over theguide bar 16 and out beneath the bar 15, wlth its inner or abutting edge in contact with the inner walls 25 and 26 of the brackets 11 and or body portion of the material; also that if the roductions requiredwmly an overlap P f the adjoining edges, the guide 9 could be dispensed withanrl the edge of the main or body portion of the material brought into guiding contactwitldthe edge 27 of said base-plate. To meet the requirements of manufacturers generally, the fmain guiding device is furnished with or without the guide 9 and with or without the bracket 11 eX- tended downward to the lower surface of the base-plate 1.
