Der durch Patent Nr. 71626 nebst Zusatz-Patent Nr. 75355 geschützte Stickrahmen ist daselbst in der Anwendung bei einer Nähmaschine mit senkrecht arbeitenden Nadeln beschrieben, es nimmt also der Rahmen waagrechte Lage ein.The embroidery hoop protected by patent no. 71626 together with additional patent no. 75355 is described there in the application of a sewing machine with vertically working needles, so the frame assumes a horizontal position.

Durch den vorliegenden Zusatz soll die Anwendbarkeit des Rahmens in der Art erweitert werden, dafs derselbe auch in senkrechter Lage, d. h. in Verbindung mit einer Maschine, deren Nadeln in waagrechter Lage sticken, brauchbar wird. Die hierzu nöthigen besonderen Einrichtungen sind in Nachfolgendem beschrieben und auf den beiliegenden Zeichnungen in einem Beispiel veranschaulicht.The present addition is intended to extend the applicability of the framework in the manner become, that it is also in a vertical position, i.e. H. in connection with a machine whose Embroider needles in a horizontal position, becomes useful. The special facilities necessary for this are described below and illustrated in an example in the accompanying drawings.

Wie insbesondere Fig. 2 ersehen läfst, wird der Stickrahmen α α, auf welchen, wie in Fig. 5 und 6 punktirt angedeutet, der zu bestickende Stoff X mittelst der Walzen b b gespannt wird, durch Flantschstücke c c und Schrauben an den mit dem Storchschnabel zusammenhängenden Träger dBd befestigt, so dafs er leicht davon abgenommen werden kann.In particular Fig. 2 läfst seen, the embroidery frame is α α, on which, as shown in Fig. 5 and 6 indicated dotted, of the rolls by means of fabric to be embroidered X is bb tensioned cc by Flantschstücke and contiguous screws on the pantograph Carrier dBd attached so that it can be easily removed from it.

Der Stickrahmenträger ist vor der Stichplatte A A angeordnet und setzt sich zusammen aus zwei Schienen d d, welche in nachbeschriebener Weise an das Lineal B des Storchschnabels angeschlossen sind; er führt sich mittelst senkrechter Walzen e e (Fig. 2, 5 und 6) zwischen im Gestell waagrecht gelagerten Walzenpaaren ff so dafs ihm Bewegungsfreiheit in allen Richtungen gesichert ist.The embroidery frame carrier is arranged in front of the needle plate AA and is composed of two rails dd, which are connected to the ruler B of the cranesbill in the manner described below; it is guided by means of vertical rollers ee (FIGS. 2, 5 and 6) between pairs of rollers ff mounted horizontally in the frame so that freedom of movement is secured in all directions.

Um die Lage des Stickrahmens bezüglich der Nadeln in der Höhen- und Seitenrichtung beliebig regeln und nach Vollendung einer Bestickungszone die Arbeit für das Besticken einer folgenden Zone leicht wieder aufnehmen zu können, ist die Verbindung zwischen Lineal B und Schienen d d vermittelst Gleitstücke m (s. die Einzelansichten Fig. 3) hergestellt, welche Verschiebung der Schienen d unter rechtem Winkel zum Lineal B gestatten. Die Feststellung der Schiene d in der neuen Lage geschieht mittelst Druckschrauben. Um die Einstellung zu erleichtern, sind sowohl die Schienen ei, wie das Lineal B mit Millimetertheilung versehen. Aehnliche, auf am Gestell befestigten Schienen ο sich führende Gleitstücke m¹ m^l ermöglichen, den Rahmen am Ort festzuhalten, währenddem man die Schrauben der Gleitstücke m m behufs der Rahmenverstellung löst.In order to adjust the position of the embroidery hoop with respect to the needles in the vertical and lateral direction as required and to be able to easily resume work for embroidering a subsequent zone after completion of an embroidery zone, the connection between ruler B and rails dd is made by sliding pieces m (see Fig. the individual views Fig. 3) produced, which allow displacement of the rails d at right angles to the ruler B. The fixing of the rail d in the new position is done by means of pressure screws. In order to facilitate the adjustment, both the rails ei and the ruler B are provided with millimeter divisions. Similar to fixed to the frame rails, leading sliders ο m ¹ m ^l allow to hold the frame in place, one during which the screws of the sliders mm solves behufs the frame adjustment.

Claims

the rail t carrying the needles χ is suspended at the ends by means of joints (FIGS. 5 and 6), so that it can be folded back with the needles, as indicated by the arrow in FIG. 5, and then the frame α α can be pulled out upwards .

Any other suitable means can be used to balance the weight of the frame and the fabric stretched on it. The related device illustrated in FIGS. 1, 4 and 5 consists in that a flexible metal band g guided over a roller i is fastened at one end to a transverse rail h connecting the rails dd at the bottom and an adjustable weight ρ is attached to the free end . In order to keep the displaceability of the frame free of any hindrance, the axis k of the roller i is supported in the grooves of two loose disks /, the pins of which are fastened in the machine frame.

In order to communicate the parallel movements to the ruler B, the device described in the additional patent no. 75355 is preferably used, consisting of two disks QQ ¹ coupled to one another by a metal band q , one of which is driven by the cranesbill ruler η, and with which the ruler B is connected by short, equally long and parallel arms rr.

From the foregoing it can be inferred that the above is perpendicular arranged embroidery frames with parallel guides that are used to stretch the to be embroidered according to the required dimensions, as well as that it can easily be obtained from his wearer can be released, which enables him to carry out the covering to lay flat on a table or according to the progress of the embroidery to adjust.

'Sponsorship τ claim:

An embroidery frame with parallel guide for sewing machines protected by patent no. 71626 type, provided with the same behufs vertical arrangement of parallel operations with the protected in patent no. 75355 means embroidery frame in the horizontal position of the needles of the embroidery frame carrier (d), with which the actual embroidery frame (ab) is connected in an easily detachable manner, lies vertically behind the needle plate (A) and is adjustably connected to the cranesbill ruler (B) by means of sliding pieces (m) .
