SEWING-MACHlNE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 569,773, dated October 20, 1896.

Application filed February 26, 1896. Serial No. 580,808. (No model.)

To all 1071,0721, it Ill-U4] concern.-

Be it known that 1, JAMES WALKER SI- MoNs, a citizen of the United States, residing at Port Chester, in the county of \Vestchester and State of New York, have invented certain new and useful Improvements in Sewing- .Machine Attachments, of which the following is a specification.

This invention relates to attachments for sewing-machines, and particularly to what are known as fold-gages.

The object of my invention is to overcome the defects inherent in constructions now known to me and to provide a fold-gage having a vertical adjustment preferably on the face-plate or head of the sewing-machine frame, although it may be located on any other convenient part of the frame, and comprising a long stem or body to be adjustably fitted in a clamp of suitable construction on said head and two right-angular bent portions at its operative end, one of said bent portions serving to smooth out wrinkles, cc. from the material and the other operating as the fold-gage proper.

In the drawings accompanying and form ing part of this specification, Figure 1 is a perspective View of part of a sewing-machine frame, showing the fold-gage in position thereon. Fig. 2 is a plan View of the clamp by which the fold-gage is adjustably supported. Fig. 3 is a detail view of the guide for the stem of the fold-gage, a portion of the frame being shown in section. Fig. 4 is a perspective view of one of the interchangeable fold-gages; and Fig. 5 is a sectional view showing how the gage operates with the usual hemmer, which may be substituted for the resser-foot shown in Fig. 1.

Similar characters designate like parts in all the figures of the drawings.

The numeral 1 represents the usual head part of the frame of a sewing-machine, 2 the needle-bar, and 3 the presser-bar of such machine.

The numeral 4. represents the improved fo1d-gage, comprising a long stem or exten sion at, a right-angular bent portion 4 and another portion 4:, bent at right angles to the part 4 The numeral 5 represents a clamp having a stem 5 secured by a screw or other fastening device 6 to the head of the machine and also having a thickened split portion 5 perforated at to receive the stem of the foldgage, said perforation being large enough to accommodate different sizes of gages having stems of varying diameters. A screw 7 is provided which bears against the gage, and another screw 8 is employed for adjusting the jaws of the clamp, and by means of these screws the fold-gage is fixedly secured in position. An additional clamping and guiding means for the stem of the fold-gage is shown, consisting of a bracket 9, secured to the ma chine-head or face-plate by a screw 10, said bracket being provided with two perforated ears or lips 9, through which the stem passes. The perforations in said ears are shown as somewhat larger than necessary to lit the stem of the fold-gage in position for the purpose of guiding and holding fold-gages having stems of different diameters. The screw 10 engages with a thread or nut in bracket 9 and passes loosely through the head or front plate of the machine, thereby serving two purposesone of clamping the bracket to said head or front plate and the other of securin g the fold-gage above the lower clamp 5, so that said gage will be fixedly held in the desired adjusted position to suit the thick ness of the material being sewed. The point of screw 10 bears on that portion of stem r located between the arms of the bracket, and

hence tends to slightly deflect or bend the same betweensaid arms, thereby holding said stem fixedly in posit-ion above the lower clamp and rendering the fold-gage secure against displacement.

lVhile the guiding and holding bracket is shown as located about midway the faceplate, yet, as is obvious, it may be placed near the top of said plate or at any other convenient point thereon either above or below the clamp 5. It is also obvious that other forms of clamps and guides maybe employed for guiding and holding the fold-gage in position at two different points on the machinehead without departing from my invention.

At Fig. 4 is shown a fold-gage of greater dimensions than that represented in Fig. 1, and it is to be understood that a series of interchangeable fold-gages are to be provided to suit'any width of fold desired.

In Fig. 5 is represented a common form of hemmin g presser-foot 11, which may be placed on. the resser-bar as a substitute for the Presser-foot shown in Fig. 1, if deemed necessary or advisable. The hemming prcsserfoot is provided with the usual needle-hole, curling-finger 12, passage-Way 13, and solid separator 15, and other common features unnecessary to mention, and with a shank 16, corresponding with that of the other presserfeet of the machine on which the attachment is to be used, and this may be any type of sewing-machine.

At 17 is represented the cloth orother material being sewed, 17 representing the fold thereof.

A fold-gage to suit the fold or hem desired having been placed in position, the cloth or other material is placed under the presserfoot and a fold of the desired width is turned over the effective portions 4 and 4 of said gage. The presser-foot is then lowered and the material is passed beneath the needle and is stitched in the usual manner, the part 4 of the gage serving to guide the fold and the part 4 to level and smooth the material on the plate of "the machine as it passes beneath the needle.

Having thus described my invention, What I claim, and desire to secure by Letters Patout, is

1. The combination witha sewing-machine, of two guiding devices detachably connected to said machine at points one above the other; and a fold-gage vertically adjustable in said guiding devices.

2. The combination with a sewing-machine head, of a fold-gage having a relatively long stem; and clamping means for said stem, located at different points on the head, whereby the device is maintained in vertical alinement. 1

3. A fold-gage comprising an elongated vertical bar bent at its lower end to form two right-angular portions, one extending transversely to the elongated bar and the other extending transversely to said elongated bar and to its other angular portion.

at. The combination with a sewing-machine head, of a perforated split clamp attached to said head; a pair of clamping devices carried by said clamp; a fold-gage having a perpendicular stem extending through said perforation and secured therein by said clamping devices; and a second clamp also secured to the head and engaging the stem at another point in the length thereof.
