Description

  

  Zange mit auswechselbaren Formen zum Pressen von gewölbten Uhrgläsern  aus unzerbrechlichem Material.         Gegenstand    .der Erfindung ist eine Zange  mit auswechselbaren Formen, mittelst wel  cher es jedem Uhrmacher und Juwelier mög  lich ist, sich selbst gewölbte Uhrgläser von  jeder gewünschten Form und Grösse aus un  zerbrechlichem Material schnell und billig       herzustellen.     



  In der Zeichnung, welche ein Ausfüh  rungsbeispiel des Erfindungsgegenstandes  veranschaulicht, ist. in     Fig.    1 die Zange und  in     F'ig.    2 und 3 sind die auswechselbaren  Formen derselben dargestellt.  



  Die Zange ist so hergestellt, dass das vor  dere Ende des Zangenschenkels     a    eine Auf  legefläche b für -die untere Form c und das  vordere Ende des Zangenschenkels d eine  Stützfläche e für die obere Form f bildet.  Damit die Formen     c,    f beim Gebrauch der  Zange festliegen, kommt die Form c mit  einem Zapfen<I>g</I> in eine passende Vertiefung<I>k</I>  des Zangenschenkels<I>a</I> und .die Form<I>f</I> mit  einem Zapfen h in eine passende Vertiefung i  des Zangenschenkels d zu stehen.    Beim Pressen der Uhrgläser werden die  Formen c, f in die Zange eingelegt und das  unzerbrechliche Material durch Schliessen der  Zange zwischen den Formen entsprechend  gepresst.

   Die geschlossene Zange wird eine  kurze Zeit in heisses Wasser gehalten, worauf  ,das Ganze abgekühlt und das gepresste Ma  terial an den Kanten der Formen c, f be  schnitten wird. Das Uhrglas ist hierauf fer  tiggestellt.  



  Dadurch, dass die Formen c, f auswech  selbar sind, können beliebige Formen in die  Zange eingesetzt und dadurch beliebig grosse  und geformte Uhrgläser mit der Zange ge  presst werden.



  Pliers with interchangeable shapes for pressing curved watch glasses made of unbreakable material. The subject of the invention is a pair of pliers with interchangeable shapes, by means of which it is possible for every watchmaker and jeweler to make domed watch glasses of any desired shape and size from unbreakable material quickly and cheaply.



  In the drawing, which illustrates a Ausfüh approximately example of the subject invention is. in Fig. 1 the pliers and in F'ig. 2 and 3 the interchangeable forms of the same are shown.



  The pliers are manufactured in such a way that the front end of the pliers limb a forms a support surface b for the lower mold c and the front end of the pliers limb d forms a support surface e for the upper mold f. So that the shapes c, f are fixed when the pliers are used, the shape c with a pin <I> g </I> comes into a suitable recess <I> k </I> of the pliers leg <I> a </I> and .the shape <I> f </I> with a pin h to stand in a matching recess i of the pliers leg d. When pressing the watch glasses, the shapes c, f are inserted into the pliers and the unbreakable material is pressed between the shapes by closing the pliers.

   The closed pliers are held in hot water for a short time, after which the whole thing is cooled down and the pressed material is cut at the edges of the forms c, f. The watch glass is then finished.



  Because the shapes c, f are interchangeable, any shape can be inserted into the pliers, and watch glasses of any size and shape can be pressed with the pliers.
