Specification of Letters Patent.

Patented May 28, 1907.

Application filed April 3, 1907. Serial No. 366,223.

T at whom it may concern:

Be it known that JOHN M. GREIST, deceased, late a citizen of the United States, and a resident of New Haven, county of New Haven, and State of Connecticut, did invent certain new and useful Improvements in Sewing-Machine Hemmers, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to sewing machine hemmers of that class in which certain parts are made laterally adjustable so that the hemmers are adapted to form hems of different widths; and the invention has for its object to provide an adjustable hemmer, of simple construction, in which the parts are so arranged that the work, in making hems of any desired width, can be accurately and con-. veniently guided to the needle of the machine.

In the accompanying drawings, Figures 1 and 2 are plan views of the improved hemmer with the parts differently adjusted in the two views, and Figs. 3 and 4 are front views with the parts adjusted as in Figs. 1 and 2, respectively. Fig. 5 is a side view and Fig. 6 a bottom view of the improved hemmer.

Referring to the drawings, 12 denotes a presser-foot having a shank 13 for attaching said presser-foot and the hemmer supported thereby to the resser-bar of the sewing machine. Riveted or otherwise suitably secured to the presserfoot 12 is aplate 14 having downturned lips 15 embracing the presser-foot and having a forwardly extending finger 16 the front end of which projects laterally and is bent over upward to form a hooked lip or guide 17 from which extends rearwardly in the line of the feed of the work, or approximately so, a stationary finger 18. Another member or arm 19, fixed to said presser-foot and preferably formed separate from said plate 14, is extended laterally to serve as a support for the sliding adjustable part of the hemmer, said part or arm 19 having a slot 20 which is preferably formed slightly diagonal to the direction in which the work is passed through the hemmer.

The adjustable part of the hemmer comprises a sliding plate 21 having a slot 22 receiving a stud or pin 23 mounted on the finger 16, said stud or pin being suitably threaded for the reception of a set-nut 2 1 by which the sliding plate 21 and the parts connected therewith or carried thereby may be secured in any desired position of adjustment. The plate 21 has a neck portion 25 fitting in the slot 20 of the plate or part 19, so that the said sliding plate 21 is guided in its lateral adjustments or movements by said slot 20 as also by the stud or pin 23. Below the neck 25 and integral therewith is a curved guide 26 from which extends laterally the work-supporting arm 27. The guide 26 is preferably provided at its bottom with the inwardly projecting lug 34. At its right end the sliding plate 21 is curved dovmward at 28, and extended forward to form a finger 29 to which finger is pivotally attached a link 30 the right hand end of which is curved upward to form a hooked lip or guide 31 which is preferably about the size of the stationary hooked lip or guide 17 before referred to, the said hooked lip or guide 31 being connected by a swinging link 32 with the forward end of the finger 18, said links being thus jointed together at 35, and being also jointed to the adjustable finger 29 and to the stationary or fixed finger 18, respectively.

The plate or part 19 is turned down at its left hand end to form a hooked lip or guide 33. This hooked lip or guide 33 and the upwardly turned hooked lip or 'guide 17 form, together, and in co-operation with the curved guide 26 and the lip or guide 31,- what may be termed the scroll part of the hemmer which turns over and in the edge of a piece of goods to form the hem, and the finger 18 extending forward from the lip or guide 17 to or past the lip or guide 33 serves partly as the tongue of the hemmer.

Whenthe parts are in the position of adjustment shown in Figs. 2 and 1, for forming narrow hems, the lip or guide 31 on the link 30 is brought into register or alinement with the lip or guide 17, and forms practically a forward continuation of said lip or guide 17. In this position of the parts the swinging link 32 overlies both of said lips or guides 17 and 31 so that it supplements the finger 18 as the tongue part of the hemmer. When, however, the hemmer is adjusted for wider hems,

as in Figs. 1 and 3, the swinging link 32 is moved to the right, so that said link 32 and the finger 18 together with the li or guide 31 serve as a widened-out tongue or the hemmer. In other words, the swinging links 30 and 32, the lip 31 on the former, and the finger 18, taken together, form what may properly be termed an expansible and contractible tongue for the adjustable hemmer; so that whatever may be the position of adjustment of the sliding plate 21 and the parts carried thereby the said tongue, over which the section of cloth forming the hem is folded, will properly support the work in making hems of different widths. fore avoids the objection to some forms of adjustable hemmers heretofore in use and in connection with which interchangeable tongues of different widths were required to properly support the work in making hems of different widths.

From the foregoing it will be seen that the improved hemmer comprises two stationary or fixed co-operating and-oppositely turned and oppositely faced hooked lips or guides 17 and 33, the former of which is provided with the stationary or fixed forwardly extending finger or tongue 18, said improved hemmer also comprising the adjustable turning-over guide 26 and the adjustable hooked lip or guide 31 'co-operating with said turning-over guide 26 in supporting the work, particularly when the device is adjusted for wide hems; and it will also be seen that the improved hemmer further comprises an expansible and contractible tongue comprising one stationary part, to wit, the finger 18, and two adjustable parts, to wit, the swinging link 30 with its lip or guide 31, and the swinging link 32.

It will therefore be understood that this invention provides a simple and compact adjustable hemmer having an expanding and contracting tongue, and the whole device, being mostly stamped out of sheet metal, is capable of being manufactured at little cost, while it is convenient and efiicient in use.

Having thus described the said invention we claim:

1. An adjustable sewing machine hemmer comprising two oppositely facing, sta tionary or fixed edge-turning lips or guides, two parts or members on each of which one of said lips or guides is formed, and an expansible and contractible tongue comprising one stationary or fixed part and two adjustable or movable parts.
