' SEWING-MACHINE ATTACHMENT.

Application filed. June 12, 1922. Serial No. 567,697.

To all whom it may concern:

Be it known that I, BENJAMAN C. PENN, a citizen of the United States, residing at Greenville, in the county of VVashing-ton and State of. Mississippi, have invented a.

new and useful Sewing-Machine Attachment, of which the following is aspecifica tion.

This invention relates to sewing machine attachments, and more particularly to guides to be used to gauge the distance between rows when a number of rows of stitching is to be made.

The object of the invention is to provide a device of this character for attachment to the presser foot bar of a sewing machine to be used when running successive rows of stitching to space them uniform distances apart, and which may be adjusted to vary the space between the rows.

Vl ith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings 2 Figure 1 represents a perspective view of a part of a sewing machine head, and a presser bar showing the attachment constituting this invention applied thereto, the needle bar being omitted.

Fig. 2 is a detail perspective view of the adjusting rod detached, and

Fig. 3 is a longitudinal section through the rod supporting means.

In the embodiment illustrated, a portion of a sewing machine head is shown at 1, which may be of any type or form, and which carries a needle bar (not shown), and a presser bar 2 which latter carries at its lower end an ordinary presser foot 3 de tachably mounted on the bar.

The gauge or guide constituting this in vention comprises ahead 5 adapted to be slidably and detachably mounted on the presser bar 2, being here shown in the form of a split ring having laterally extending arms 6 and 7 with registering bores formed therein and extending at right angles to the bore which receives the presser foot. A bolt 8 is mounted in these arms with the head 9 thereof abutting the outer face of one of them as is shown. clearly in Fig. 3. This bolt 8 has the threaded portion thereof projecting beyond the arm 7 and is equipped with a tightening nut 10 having a knurled head 11 to facilitate the turning thereof. The bolt 8 has a longitudinally extending slot 12 formed intermediate the ends thereof, through which the adjusting rod 15 is designed to extend, as will be hereinafter more fully described. A washer 13 is arranged on the bolt between the nut 10 and the adjusting rod 15.

The adjusting rod or gauge bar 15 is here shown in the form of a heavy wire of any described or suitable length slidably mounted in the slot 12 of the bolt 8, and which is designed to be clamped between the outer face of the arm 7 and the washer 13 when the nut is tightened up. The bar 15 has an elbow-shaped arm 16 extending laterally from one end thereof, the member 18 of said arm extending substantially at right angles to the member 17 and having its terminal bent upwardly and inwardly to form. an eye as shown at 19, to avoid all possibility of said terminal hooking in and tearing the fabric of the goods in connection with which the device is to be used.

This attachment is especially designed for regulating or gauging the distance between rows of stitching, although obviousl', it may be used to gauge the distance between tucks or to gauge the width of hems.

In the use of the attachment, the head 5 is clamped to the presser bar 2 in the position shown in Fig. 1, with the rod 15 extending transversely through the slot 12 in the bolt 8, whereby said rod is positioned horizontally with the elbow-shaped arm 16 thereof depending from one end with the member 18 of said arm arranged to overlie the row of stitching which is first formed and from which it is designed to space another row to be made. It is of course understood that the rod 15 may be adjusted in the bolt 8 to position the arm 16 toward or away from the presser foot to vary the distance between the rows of stitching.

lit is also to be understood that the rod 15 may be used as shown in Fig. 1, or it may be removed from the bolt and reversed with the arm 16 located on the opposite side of the presser bar if desired, according to the way in which the operator holds the goods being stitched.

This attachment may be used in connection with any form of sewing machine having a presser foot bar, the clamping arms 6 and 7 adapting the head 5 to fit bars of different sizes.

I claim:

1. An attachment of the class described comprising a head to be*slidaibly mounted on a presser bar of a sewing machine and having laterally extending clamping arms, a bolt mounted in said arms and having an aperture extending transversely therethrough a rod mounted for longitudinal adjustment in said aperture and a clamping nut carried by the bolt to clamp said rod between it and one of said arms.

2. An attachment of the class described comprising ahead in the form of a split ring having arms extending laterally from the split ends thereof, said arms being apertured with the apertures extending at right angles to the axis 01? the opening in the head, a bolt extending through the apertures in said arms and longitudinally slotted beyond the arms, a clamping nut carried by said bolt and a rod adapted to extend through the slotted bolt and he clamped between the nut and one of said arms said rod having a laterally extending gauge member.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two Witnesses.
