Description
Handradreibungskupplung für Nähmaschinen o. dgl. Gegenstand der Erfindung ist eine Reibungskupplung für Handräder von Nähmaschinen o. dgl., bestehend aus einer auf einen Teil ihrer Länge an diametral gegenüberliegenden Stellen in axialer Richtung aufgeschlitzten zylindrischen Kappe als einem Kupplungsteil, einem in die Kappe mit geringem Zwischenraum hineinragenden Zylinder als anderem Kupplungsteil und ,einem aüi dem Mantel der Kappe unter Spannung liegenden Schraubenfederring, der zum Kuppeln von dem nichtgespaltenen Teil der Kappe auf den gespaltenen gerollt wird.Handwheel friction clutch for sewing machines or the like. The subject of the invention is a friction clutch for handwheels of sewing machines or the like, consisting of one for part of its length at diametrically opposite points in the axial direction Direction slit cylindrical cap as a coupling part, one in the Cap with a small gap protruding cylinder as another coupling part and, a helical spring washer which is under tension on the shell of the cap, which is rolled from the non-split part of the cap to the split one for coupling will.
Schraubenfederringe lassen sich auf einer zylindrischer. Fläche äußerst leicht hin und her rollen, wobei sie auf die sie tragende Fläche einen mehr als sechsfachen Druck ihrer eigenen Spannung ausüben. Diese neue Erkenntnis wird hier zur Herausbildung,einer Kupplung für Nähmaschinen nutzbar gemacht. Bekanntlich bestehen solche Kupplungen in einfachster Form bisher aus .einer Druckschraube, die die zu verbindenden .Teile mit Hilfe einer Zwischenlegscheibe gegeneiüanderpreßt. Zur Betätigung gehören immer zwei Hände. Wendet man die neue Kupplung an, so. kann man die Betätigung mit einer Hand und ohne Kraftaufwendung vornehmen, während das Anziehen der bekannten Druckschraube für Frauenhände mitunter ziemlich anstrengend ist. Auf der Zeichnung ist der Erfindungsgegenstand in einem Ausführungsbeispiel.veranschaulicht.Coil spring washers can be found on a cylindrical. Area extremely Roll slightly back and forth, placing more than one on the surface that supports them exert sixfold pressure of their own tension. This new knowledge is here made usable for the formation of a clutch for sewing machines. As is well known, exist such couplings in the simplest form so far from .einer pressure screw that the to The connecting parts are pressed against one another with the help of an washer. For actuation always belong to two hands. If you use the new clutch, so. one can do the actuation Do it with one hand and without the use of force while tightening the familiar Pressure screw is sometimes quite exhausting for women's hands. On the drawing is the subject matter of the invention in an exemplary embodiment.
Die Nähmaschinenwelle io trägt am Ende die gespaltene Kappe 12 als die eine Kupplungshälfte, die die Nabe i i des Triebrades der Maschine als andere Kupplungshälfte umfaßt. Ein Schraubenfederring 13 ist auf der Kappe 12 verrollbar. Er wird durch ,einen Kniehebel i q. verrollt, der bei 15 an das Maschinengestell angelenkt ist.,The sewing machine shaft io carries at the end the split cap 12 as the one coupling half which comprises the hub ii of the drive wheel of the machine as the other coupling half. A helical spring ring 13 can be rolled on the cap 12. He is by, a toggle lever i q. rolled, which is hinged to the machine frame at 15.,
