KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die bekannten Knopflochscheeren leiden alle an dem Nachtheil .einer unvollkommenen Stellvorrichtung, da diese sich während des Gebrauches leicht verstellt, bald abnutzt und so schwer auszubessern ist, dafs meistens durch die Kosten dafür der Werth der ganzen Scheere überstiegen wird. Auch bei der unter Nr. 58099 patentirten Knopflochscheere ist eine Unverstellbarkeit beim Gebrauch nicht gewährleistet.The well-known buttonhole scissors all suffer from the disadvantage .einer imperfect adjusting device, since they are in use during use slightly misplaced, soon worn out and so difficult to repair that it is mostly done through the cost of it will exceed the value of the whole scissors. Also with the one under No. 58099 patented buttonhole scissors cannot be adjusted during use.
Zur Beseitigung dieser Uebelstände besteht bei der neuen, in Fig. 1 bis 4 dargestellten Knopflochscheere die Stellvorrichtung einfach aus einer Schraube B (Fig. 3), welche in dem einen geschlitzten Schenkel A der Scheere verschiebbar ist. Diese Schraube besitzt eine birnenförmige Mutter b, führt sich im Schlitz a des Schenkels A (Fig. 2) mittelst ihres kantigen Bolzentheiles bl undrehbar und legt sich mit ihrem Kopf b2 aufsen gegen den Schenkel A an. Schenkel A ist auf der Innenseite mit Riffeln oder Zähnen versehen, in welche die Mutter b nach erfolgtem Anziehen eingreift, sich dadurch an beliebiger Stelle des Schenkels A feststellt und somit ein verschieden weites Schliefsen der Scheerenblätter gestattet (s. z. B.To eliminate these inconveniences, in the new buttonhole scissors shown in FIGS. 1 to 4, the adjusting device simply consists of a screw B (FIG. 3) which can be displaced in one of the slotted legs A of the scissors. This screw has a pear-shaped nut b, is guided in the slot a of the leg A (FIG. 2) by means of its angular bolt part b l in a non-rotatable manner and its head b 2 rests against the leg A on the outside. Leg A is provided with grooves or teeth on the inside, in which the nut b engages after tightening, thereby locking itself at any point on leg A and thus allowing the scissor blades to close at different distances (see e.g.
Fig. 4)·Fig. 4)
Die Schraube B kann nach Vorstehendem sich während des Gebrauchs der Scheere nicht verstellen und somit auch nicht ein Schneiden ungleichmäfsiger Knopflöcher zulassen. Ebenso läfst sich nach Lösen der Mutter b die ganze Schraube B (nach eventuell erfolgter Abnutzung derselben) leicht aus der Scheere herausnehmen und beliebig oft durch eine neue derartige, käuflich gehaltene Schraube ersetzen, ohne an der Scheere selbst irgend welche Reparaturen vornehmen zu müssen.According to the foregoing, the screw B cannot be adjusted while the scissors are in use and therefore cannot allow the cutting of uneven buttonholes. Likewise, after loosening the nut b, the entire screw B can be easily removed from the scissors (after any wear and tear) and replaced as often as desired with a new, commercially available screw without having to make any repairs to the scissors itself.
