Description

Spannvorrichtung für die Tastenhebelfedern von Schreibmaschinen. Die Erfindung bezieht sich auf eine Spannvorrichtung für die Tastenhebelfedern von Schreibmaschinen, bei der die Federn in einen gemeinsamen, verstellbaren Halber eingehängt sind-, und besteht darin, daß an dem Halter eine Schiene mit Zacken angeordnet ist, ih. denen die Einhängelöcher für die Federn in verschiedenen Höhen angebracht sind. Durch diese Ausbildung ist es möglich, die Schraubenfedern der verschieden langen Tastenhebel vollkommen gleich zu machen und alle auf einmal in bestimmtem Ausmaße verschieden stark anzuspannen, so daß durch das Anspannen einer Feder auch alle übrigen die jeweils zweckmäßige Spannung erhalten. In der Zeichnung ist die Erfindung veranschaulicht, und zwar zeigt: Abb. t eine Seitenansicht und Abb. z .die Oberansicht.Clamping device for the key lever springs of typewriters. the The invention relates to a tensioning device for the key lever springs of typewriters, in which the springs are suspended in a common, adjustable half, and consists in that a rail with prongs is arranged on the holder, ih. where the suspension holes for the springs are made at different heights. This training makes it possible to use the coil springs of different lengths To make key levers completely the same and all at once to a certain extent to tension differently, so that by tensioning one spring also all the rest of the time, get the appropriate voltage. In the drawing is the invention Illustrates, namely: Fig. t shows a side view and Fig. z. The top view.

Werden beispielsweise vier Reihen hintereinander angeordneter Tasten an einer Schreibmaschine angenommen, so sind je vier nebeneänanderliegende Tastenhebel. verschieden lang. Die unteren Enden der vier zugehörigen Federn. c sind in Löchern c' eingehängt, welche in den zugehörigen Zacken d' einer sich quer zu den Tastenhebeln unter demselben erstraekkenden Schiene d verschieden hochangebracht sind. Diese Schiene ist zwischen zwei Flacheisen einsgelegt und mit denselben zu einem Stücke (Halter) verbunden, das in bekannter Weise durch die Schrauben a, b auf- und abwärts bewegt werden kann.If, for example, four rows of keys arranged one behind the other are assumed on a typewriter, there are four key levers lying next to one another. different length. The lower ends of the four associated springs. c are hooked into holes c 'which are made differently high in the associated prongs d' of a transverse to the key levers under the same straight rail d. This rail is inserted between two flat irons and connected to the same to form a piece (holder) that can be moved up and down in a known manner by means of the screws a, b.

Alit der Einstellung der Spannung einer Feder c erfolgt demnach gleichzeitig auch die Einstellung der Spannung aller übrigen Federn auf entsprechende Höhe.The adjustment of the tension of a spring c therefore takes place at the same time also the adjustment of the tension of all other springs to the appropriate level.
