PRESSUREFEET FOR VERTlCAL-NEEDLE EMBROIDERY MACHINES.

Application filed April 8, 1925, Serial No. 21,542, and in Germany May 22, 1924.

hly intention relates to embroidery 1nachines ot the sewing machine type; more especially it relates to the provision of a double presse1--toot "for embroidery machines of said type. i t

lVith machines of the type mentioned which operate with oscillating or laterally "vibrating needles, and with two Presser-feet which can be thrown into and out of work engaging position independently of one another, a bread; in the thread is caused easily by the thread coming from the needle being caught in the space between the two pres i feet when the needle is being moved laterally, the thread being then subjected to excessive strain. i

The object of my invention is to overcome that drawback and I attain that object, firstly,

by letting the slot which must be provided in one of the presser-plates extend into a tongue projecting forth laterally in the direction of the other presser-plate whereby it is rendered possible to form for the thread a guide-slot which is closed all-around; and secondly, by providing in the other presserplate a recess adapted to receive the tongue provided on the first presscr-plate, as men tioned.

My invention is illustrated diagrammatically and by way of example, in the accompanying drawings in which Figures 1 and 2 are front-views of the two pressenfeet, detached from the presser rods;vFigure 3 is a plan of both presseu'feet, which here are shown side by side, as near one another as possible; Figures l and 5 are side-views of the two presser-feet, one being shown from the lelthand side, the other from the righthand side: and Figure 6 is a view similar to Fig. 3 and shows a modification of the feet, as is all more fully described hereinafter.

l-leterriug to Figures L5. each ot the two ]In-esse1-.t'eet is provided with a presser-plate 1i and 1 respectively, which is bent upwardly at its free end 2, and with a fastening plato- S, the rear face of which IS provided with ribs l by which the proper horizontal position of the presser-plate on the resser-rod is ensured in every vertical position of each presser-foot on its respective rod.

The two presser-feet can be thrown into, and out of, work engaging position independ= ently of one another. They are required in all cases in which it may be desired to con nect by a fancy-stitch two fabric-edges loouted at some distance from one another. It

is in such cases necessary to adjust the two lalsric-sdges independently of one another,

, and to re-adjust them while the sewing pro-t that plate itself. :The bottomtacc of the 1,

tongue lies a little higher than the bottom face of that plate so that the tongue presses upon the tabric not as strongly as does the said plate, whereby it resultsthat after the other resser-plate (1') has been lifted, the fabricpart lying below it can be shifted. easily in spite of the tongue 5 extending over it. v v

The presser-toot is, furthermore, provided with a comparatively very long slot- 6 located lransversely with respect to thedireetion of feed of the fabric, one half of this slot lying in the press'er-plate l proper andbthe other half lying in the tongue 5. The thread can travel along to and fro in the slot 6 when the needle is moved laterally, there beingnowno opportunity to get entangled, whereby the drawback mentioned in the introductory part of this specification is completely obviated.

Corresponding to the laterally projecting tongue 5 of the presser-plate 1, the pressen plate 1 is provided with a recess of such size that the tongue 5 can be received therein when the two Presser-plates are located closcprovement described can be modified in various ways without departing from the gist of the invention. One such modification is illustrated inFig. 6, in which the threadguiding slot is provided in a separate member 50 carried by an arm 51 extending forth from a vertical rod 52; the slotted member 50 extends in to slots 7 and 7 0 provided in the two resser-plates. The rod52 may be adjusted the bottom-feces of the said press-er vertically independently of the resser-feet rods, or may be connectedwith one or-the other thereof.
