SEWING-MACHINE HEMM'ER.

SPECIFICATION forming part of Letters Patent No. 739,210, dated September 15, 1903.

Application filed November 4. 1902. Serial No. 130,110. (No model.)

To all whom it may concern:

Be it known that I, AMANDUs J OHANN AU- GUST'OESTERREICH, a citizen of the German .Empire, residing at Hamburg, Germany, have invented certain new and useful Improvements in Sewing-Machine Hemmers, of which the following is a specification, reference being. had therein to the accompanying drawings.

In the use of sewing machine hemmers making a wide fold or hem for hemstitching it is essential that the work should be guided to the stitch-formic g devices with great accuracy, particularly where the hems run across 1 each other, as in the corners of handkerchiefs, table-cloths, &c., and the hemmers heretofore in use could not always be depended on for accurate work.

This invention has for its object to provide asewing-machinehemmeradapted formaking folds or hems of different widths and which will present the goods to the stitching devices smoothly and accurately.

In the accompanying drawings, Figure 1 is a sectional elevation of the improved hemmer in operative relation to parts of a sewingmachine, but with the movable part of the hemmer adjustable laterally for the insertion of the work. Fig. 2 is a sectionalview of the hemmer with the parts in working position. Fig. 3 is a plan view of the hemmer and a part of the work-plate of the sewing-machine, showing also the work. Fig. 4 is a side view of the hemmer looking from right of. Fig. 1,

but with the interchangeable guiding-plate removed. Fig. 5 illustrates a guiding-plate of different width from that shown in Figs.

1, 2, and'3.

Referring to the drawings, a denotes part 7 of the depending head of a sewing-machine,

tue of the slot h, through which the set-screw f passes, as will be understood.

Mounted on the plate g is a block 2', having a raised tongue 70, which serves as a guide for the left-hand edge of the hem-fold, and attached toa sliding bar 052, mounted in ways on the plate (Z, is a cap n, which when in the working position (shown by Figs. 2 and 3) em braces the tongue 7c. The sliding barm is provided with a pin 0, embraced by a forked lever p, by which the cap n may be'adjusted to the different positions shown in Figs. 1 and 2, either for the convenient insertion of the work or for the hemming operation. A detent-spring q,'attached to the lower face of the lever p and having apointed free end to enter slight indentations r in the plated, serves to hold the said lever in the difierent positions to which it may be moved.

The guiding-plate s, which serves to form the right-hand edge of the hem-fold and around whichthe fabric passing beneath the plate 9 is folded, is removably supported in the said plate g. To hold the said guidingplate 3 in place, said plate is provided with a longitudinal groove f entered by a frictionspring or spring-tongue u beneath the undercut right-hand part of the block 'L'. This construction permits a guiding-plate 8 to be removed and another interchangeable guidingplate of different width to be substitutedtherefor in making hems of different widths.

In the use of the attachment the cap 91. may be shifted to the left, as shown in Fig. 1, when the work is to be inserted, and is then shifted back to the working position. (Shown in Figs. 2 and 3.) By reference to Fig. 3 it will be seen that the hem-fold in the fabric 00 overlies the guiding-plate s and the block 21, so that the goods are so disposed that when inserting the same in the hemmer the attendant can gently press them into place with the finger instead of being required to use a pointed instrument for this purpose, as with some hemmers heretofore in use, while the construction of the device is such that the hem is guided smoothly and accurately to the stitch-forming devices of the machine.

Having thus described my invention, I

claim and desire to secure by Letters Patent of the United States- 1. A sewing-machine hemmer comprising a tongue, as k, for guiding the left-hand edge of the hem fold and a removable and inter changeable guiding-plate, as s, for the right: hand ed ge of the fold, combined with a movable cap, as n, embracing said tongue, a slide by which said cap is carried, an adj listing-lever for said slide, means for holding said leverin different positions of adjustment, and means for supporting said parts from the head of a sewing-machine and above the work-plate thereof.

2. The combination with the arm 0, of the plate d, adjustably connected therewith, the plate 9 attached to said plate d and provided with the block 1' having the guiding-tongue 7c,
