vTo fall whom 'it .may concern:

.j Be' it ,known that I, WILHELM itizen of the Unite-d States, residingin the-` vio Jas-PER, a

orough of Manhattan, in the city, county,

'and State of New York, have invented new and useful Improvements in' Straw-Hat.- Sewing Machines, of which a speciiication.

4This invention relates to straw hat sewing' machines, and particularly to a 'combined pressenfoot and gage to facilitate sewing together the straw braid from which straw hats'ar'e const-ructed, valthough it is also applicable to sewing cords, braidsand other construction and j-eiiicie'nt -in operation,v `'whereby the stitching Awill always be in a lstraight line near the marginal edges of the trimmings to hats of either straw vor telt.'

.It is theebject of 4the invention to provide an improved-.sewing machine attachment 'ot this'. character, which is cheap in hat and succeeding row of braid, with such edges maintained'in rm engagement and 'av tight stitch assured.`

In the drawing accompanying and forming apart of this specification, Figure 1 is a perspective view of a Willcox & Gribbs sewing machine with4 my improved attachment applied thereto. 'Y 30 Fig. 2 is a perspective view ot my improved attachment. Fig. 3 is a side elevation of the presser toot.

'Fig 4 is a `perspective view of the gage member; and Fig. 5 is a the ladjusting screw.

Similar characters of reference designate like'parts tliroughouttl-re ditterent views of perspective view of the drawing.

In the embodiment of my. invention .illus- '.ftiated in the drawing, I have shown the same. applied to a sewing machine of the.

Willcox & Gibbs type to be used in conneCtion with a. gage 6 adjustably connected to the table 7 by. a screw 8 passing through a 1 'slot in the gage, said screw also securing a guide rod 9 having a hooked xend passing .through and extending beyond the guideA ,an'ge of the gage t3, below which guide rod,

thel braid passes. `The gage Gis adjusted a rotatable stud '10 having a ltnurled 6.o.

head and upon which stud is mounted a pinion 11 to mesh withrack teeth 12 on the gage 6- The presser f screw 'threadedend of the presser-foot b a r slot- 15' in which engages the shouldered and the following isy foot comprisesavshanlr por;4 'tion 'g1-3" having a dang/e 14 provided with a 16 to which itl is secured by .a nut. 17. The presser .bar ot the .usual construction pro-l vided with the usual means to raise and lower the same and limit the downward lmovement, a spring yiel-dingly maintaining it in its lov'verposition.- The tootproper I8 is curved upwardly at the forward end and pivotally connected to the shank 13 at the rear, end, as shown at 19,' by providing s lot ina rearwardly extending portion ot the shank and passing a pivot pin through such portions of the' shank' and foot. Y this construction, thefoot is permitted vto have an upl and down oscillatory morement parallel with the presser. bar. `Fiirther more, it will be noted that as thus. con'- structed the rear portion of the toot will always'be in substantially the same'plane,

evenvfhen it is moved to the dotted line, 'position shown in Fig. 3, the' rear portion not' being forced down when the forward.

end moves up, thereby clamping the article being'sewed between the stitch lplate and foot interfering with the proper feeding thereof `by Vthe .feeding mechanism. The

forward end of -the foot is normally forced downward and maintained away from the shank by a spring 2O one end 'of which en. gages' in a recess or socket inthe. bottom ofthe shank and the other end bearing' against the top o-the foot. A guide pin '2l connected to the foot slidably engages in an aperture or recess in the shanl, said pin prevent-ing any sidewise canting movement 'of the foot. v v v .A gage (designated in a general way by IG) to guide the edge of. the hatbeing sewed, and regulating the positionof thestitching i' shank 13, and is adjusted and vInaintajined its adjusted positions by a set screw '26 having screw threaded engagement with the shank and provided with a lmurled'head Q7 to facilitate the screwing thereof into and v6.5, the foot with a projection to engage in leo out of the shank. The screw engages in slot formed in the gage by the body 'of the shaped portion 28, which portion lalso ear- .ries one of the pins '24, and'is provided with a pair of annular shoulders 29,80 to form an' annular groove or recess inwhich the body and projecting portion 28 of the gageengages,an'd as the screw is screwed into and out of theshank it carries the gage- Wltll lt; l

In the4 operation of .sewing braid together to form a straw hat, let it be assumed that a p rt-ion of a hat has been formed,V as shown at a, (Fig.4 1,)1 andadditional braid is to be sewed thereto to finishA the hat, the said braid being indicated at b. The outer edgeof -the portion ofthe hat is run up against the side ofthe gage G passing'over the lip 23 and'beneath the presser foot and needle. The braid or that part being sewed to the already formed part of the hat is passed under 'the 'guide rod 9 with one edge bearing against the guide flange of thefgage 6, vand the other edge of the braid passing beneath the edge ofthe' gage G and under the edge'4 'of the hat. so vthat the needle will stitch through .both the formed portion of the hatandbraid. .By providing the gage with the lip ,Q3 and curving the foot up as shown the proper feeding vof the formed portionl of the hat ybelow the presser foot is assured, the

`pressure of the spring COron vthe presser foot will always maint-ain the hat and braid' in iirm engagement assuring a tight stitch, the

s'aidfoot readily giving or moving up to compensate for any unevenness in the thicknessof the braidL but still maintain the hat and braidin firm engagement and in no way interfering with the proper feeding thereof as the machine is operated;

It will be observed thatby rot-ating theadjusting stud 10 the gagel 6 may be readily moved toward or away from the stitch plate for differentwidths ofbraid, and that the Variations may be resorted to within the scope'of my invent-ion.

Having' thus described my invention, I

claim: y si y 1.-'In a straw hat sewing machine,'the

'combination with the presser-bar, of a presser-foot having a shank portion whereby it is 'detachably secured to the' presserbar, and the foot pivotally connected *to-'the shank at the rear end; a spring to normally force the foot downward awayfroin the shank; a guidepin carried lby thefoot to slidably engage in an aperture' in the bot'` toin ofthe shankto prevent sidewise movement of the'foot; and a guide adjustably carried by the shank of the foot.

In a straw hat sewing machine, the combination with ythe presser-bar, of a y presser-foot having a shank whereby it isdetachably secured to the presser bar, thefoot portion piyotally connected lto the. shank at the rear en d and curved upwardly at the forward free end; a 'spring to normally force the foot downward away from'l the-v shank; a guide pin carried bythe foot to slidably engage. in an aperture in the shank to prevent sidewise movement of thefoot: and a gage adjustably .carried by the shank of the foot. safid gage 'extending beyond'the forward end of the foot and provided with a laterally projecting lip located in a plane .below the foot and curved reversely to'the .curvature of the foot, substantially as and.

for `thepu1pose specified.
