PRESSER FOOT WELT GAUGE Filed Aug. 14, 1928 Patented May 27, 193()Y JESSE E. ivns, oF DANBURY, CONNECTICUT PRESSER-FOOT WELT (SrATJ'CurE Application led August 14, 1928. Serial No. 299,506.

This invention relates to an attachment for sewing machines, particularly to a presser foot and guiding means for folding over and guiding the edge of a hat brim while itis being stitched to form a welt.

It has for an obj ect to provide an improved form of guiding means which will give a yuniform fold to the edge of the brim anc will so guide the brim as to automatically ac commodate itself to variations in the thickness of the felt and will not interfere with the proper feed of the brim.

With the foregoing and other objects in View, the invention consists in certain novel features of construction, combinations and arrangelnents of parts as will be more fully described in connection with the accompanyn ing drawing. In this drawing,

Fig. 1 is a vertical section of the outer por tion of a hat brim and the bed plate of a sewing machine taken just in front of my improved guide, and thus showing the guide in front elevation.

Fig. 2 is a side elevation looking from the left of Fig. 1 showing the hat brim and bed plate in vertical section.

Fig. 3 is a top plan view of the device.

Fig. 4 is a side` elevation of the outer guide element.

Fig. 5 is a front elevation thereof.

Fig. 6 is a side elevation of the inner guide element, and

Fig. `7 is a front elevationthereof.

In the drawing the bed plate of a sewing machine is indicated at 10, and 11 indicates the presser bar associated with the needle 12. A portion of a felt hat brim is indicated at 13 and the folded-over edge of this brim is indicated at 14. My improved guiding means comprises a body member 15 secured to the presser' bar by any suitable means, as a screw 16, and it has a horizontal foot 17 to rest on the top of the folded-over portion 11i of the brim and hold it down on the bed plate and the feed dog 18 for the proper feeding operation.

Guiding and folding means for the hat brim comprises an outer guide 19 and an inner guide 20. The outer guide has an upright wall 21 to engage the outer edge of the of the brim andfolds it over on the top of the brim into the position for stitching, as shown in Figs. 1, 2 and 3, the line of stitching being indicated at 24. This guide element has a stem portion 25 provided with an opening 26 for mounting on a screw stud 27 carried by the body 15, and this opening is suiciently larger than the screw to permit the free end of this element to move up and down. A spring 28 on this screw stud tends to force the free end downwardly and hold the curved guide 22 against the folded edge of the brimv and the lower edge of the upright wall 21 against the top of the bed plate 10.

The inner guide 2O is similarly mounted on a screw stud 29 and its stem portion 30 i has an opening 31 to receive this stud, and is of suiiiciently larger diameter to permit `this guide element to yield verticallyaagainst the action of the spring 32 on the stud. This guide element has an upright wall 33 to engage the inner edge 23 of the folded-over welt 1i of the brim after it has been folded over on top of the brim bythe curved wall 22. A notch 34 may be provided in the in- `ner guide to permit its use with an oscillating needle if desired.

1n operation the free edge of the brim is Y folded over as indicated by the curved wall no danger of the folded-over portion 1a get- `ting under the lower edge of this guide. The -free edge is, led giving therefore, always properly guida fold of uniform width throughout the entire circumference of the brim. The outer guide 19 also yields upwardly against the action of its spring 28 so that the lower edge of the upright wall 21 always rests on the top surface of the bed plate 10, and this guide, therefore, is always in position outside the outer edge of the weit, and this mounting of the guides permits the bottom wall of the foot 17 to press down on the top of the fold 14 and give the required pressure thereon for the feed doglS to function properly. Because of these yielding mounts for the guides, differences in thicknesses of the felt does not interfere with the lower edge of the outer guide 21 resting on the bed plate or the lower edge of the inner guide restin on the top surface of the brim. The gui es are, therefore, always in proper guiding position and they do not interfere with the foot giving the proper pressure on top of the brim for a uniform and proper feed. It will be obvious the device `1s very simple in construction and is easily manipulated, that it may be easily and quickly mounted-in place of the usual presser foot on the machine, and the work is always visible to the operator.

Having thus set forth thenaturev of my invention, what I claim is:

1. In a presser yfoot for use on sewing machines in sewing the turned-over welt of a hat brim, a body portion adapted to rest on the brim andpress it againstY the feed dog, an inner and an outer guide secured to said body and adapted to independently yield upward- I v, resilient means tending to force the guides downwardly, the outer guide having a curved wall to fold over the outer portion of the brim and an upright wall to engage the outer edge of the brim, and the inner guide having an upright wall to engage the inner edge of the folded-over 'portion .of the brim.

2. In a devicev of the character described, a. bodyv member having a foot to rest onthe top of a hat brim, inner and outer guides secured to said body member and adapted to movevertically independently of each other, yielding means tending to force the guides downwardly, the outer guide having a curved wall to fold over the outer portion of the brim and an upright wall to engage the edge of the brim, and the innerguide having an upright wall ,to engagethe free edge ofthe folded-over portion.

3. In a device of the character described, a body member having afoot to rest on the top of a hat brim, inner and outer guides pivotally mounted on said member to move up and down, the outer guide having an upright wall to engage the outer edge of the brimand an upwardly and inwardly curved guide wall to foldover the outer edge of the brim, the in- `ner guide having an upright wall spaced inwardly'of the outerv ing to hold` theV tions.

4: In a device of the character described,

guide, and springs tendguides in their lower posia body member having 4'a foot to press on the top of a hat brim, an outer guide mounted to yield upwaroljyf on said member and having an upwardly and inwardly curved guide wall to fold over the free edge portion of the brim and an upright wall to engage the outer edge of the brim, and an inner guide for the folded-over free edge of the brim spaced inwardly from said outer guide.

5. In a device of the character described, a body member having a foot to press on the top of a hat brim, an outer guide member having guide walls to fold over inwardly the outer edge portion of the brim, and an inner guide spaced. inwardly of the outer guide to engage the free edge of the folded-over portion of the brim.

(i. In a device of Vthe character described, a body member having a foot to press on the top of a hat brim, an outer guide having means to fold over the free edge portion of the brim, an upwardly yieldable inner guide having an upright wall to engage the inner free edge of said 'folded portion, and yieldable means tending in its lower position.

- In a device of the character described,

:x body member having a foot to press on the top of a bat brim, studs on said body member, an inner and an outer guide having openings respecli.' ly to receive said studs, springs on the studs tending to force them downwa rdly, said outer guide having walls to fold over the outer portion of the brim and to engage the free edge of the brim, and the inner guide having a guide wall for the inner free edge of the folded-over portion.

In testin'iony whereof I affix my sigi'iature.
