Description

Press foot for sewing machines with an upwardly pivotable fabric edge stop The subject of patent 662 164 is a press foot which is subdivided several times both in the longitudinal and in the transverse direction, the individual parts of which are springy, and one of which is used to adjust the turn-up of one fabric part. serving adjustable stop carries.

It has now been found that this is important in sewing Stop on machines moving up the arm when pulling back the sewn Piece of goods is a hindrance because it results in the upward movement of the DTückerfußes the pivoting mounting of the presser foot part that carries it and is under the action of a spring is pressed against the throat plate -and thereby the sewn piece of goods on the stop Keeps hanging.

The purpose of the invention is now to avoid this disadvantage. Achieved this is due to the fact that the stop for adjusting the envelope of the one The presser foot part carrying the fabric part automatically counteracts when the D-rear foot is raised the effect of the spring from the item of goods, which usually presses it against the item of goods pivoted away.

For sewing machine presser feet with edge guides arranged on them it has already become known, the edge guide when not in use by a To pivot the hand lever upward beyond the presser foot sole, which at the same time what is achieved is that when the Ducker foot is raised, the edge guide when retracting the item of goods is not a hindrance.

This known elimination of the edge guide has opposite The object of the invention has the advantage that in this case the edge guide is automatic when lifting the presser foot swings upwards and thus a handle is spared.

The drawing shows an embodiment of the subject matter of the invention shown.

Fig. I and a show side views of a presser foot according to FIG Invention in two different positions.

The lever arm i i of the shoulder screw q. rotatable part a of subdivided presser foot, which is pressed against the item of goods by the spring 2o is up over the main part 1q. of the presser foot extended and has an inclined surface ¢ 5. On the fixed housing of the sewing machine is by screws or the like. A fixed stop 46 attached, its against the presser foot directed free end one of the inclined surface 45 correspondingly designed inclined surface 47 has. When lifting the presser foot with the, hand lever q.8 or by pressing a foot lever, the inclined surface q 5 comes to the end of the lever arm i i in sliding engagement 1141 of the inclined surface ¢ 7 of the stop q6, whereby the The presser foot part 2 is pivoted against the action of the spring 20, d. H. voti the item of goods is lifted. The stop ¢ q. can no longer stand against the throat plate move the sewing machine. and thus the withdrawal of the sewn work piece from the machine.
