PH. SCHEIDIG in FÜRTH. Spannzange.PH. SCHEIDIG in FÜRTH. Collet.
Patentirt im Deutschen Reiche vom 15. October 1878 ab.Patented in the German Empire on October 15, 1878.
Die bei Gold-, Silber- und Metallschlägereien bisher eingeführte und verwendete Spannzange, Fig. i, litt an folgenden Mängeln:The collet, which has been introduced and used in gold, silver and metal beating shops so far, Fig. I, suffered from the following defects:
1. Durch den Fufs q hatte dieselbe einen äufserst unbequemen und unsicheren Auflagepunkt, Hält z. B. der Arbeitende mit der rechten Hand die Holzzange η zum Auslegen der Goldblätter u, so ist bei beschränktem Platze ein stetes Anstofsen an den Halter op unvermeidlich.1. Due to the foot q it had an extremely uncomfortable and unsafe point of support. If, for example, the worker uses the wooden tongs η with his right hand to lay out the gold leaves u, constant contact with the holder op is inevitable when space is limited.
2. Die Vorderzange r liegt gleichfalls nicht waagerecht auf dem Tische, infolge dessen war das erforderliche spitze Anspannen der Form s ν unmöglich.2. The front pliers r also does not lie horizontally on the table, as a result of which the necessary pointed clamping of the form s ν was impossible.
Vorzüge der neuen Spannzange, Fig. 3 bis 8, sind:Advantages of the new collet, Fig. 3 to 8, are:
1. Ein Arbeiter hatte bei Anwendung der bisherigen Zange einen Tischraum von 100 cm nöthig, während durch die neue Construction 30 cm erspart werden.1. When using the previous pliers, a worker had a table space of 100 cm necessary, while the new construction saves 30 cm.
2. War beim Leeren der Form j· die alte Zange t stets sichtbar, so ist die neue, Fig. 3, vollständig verdeckt und ein Anstofsen an die Zange unmöglich geworden.2. While the old pliers t was always visible when the mold j was emptied, the new one, FIG. 3, is completely covered and it has become impossible to touch the pliers.
3. Die Form ί liegt auf dem Tische in flach auf und läfst sich durch h befestigen, und zwar parallel anspannen vermittelst des Armes ik, der an einer verstellbaren auf- und niedergehenden Säule b sich befindet.3. The mold is situated on the table in ί flat on and läfst be attached by h, and brace in parallel by means of the arm ik, the b on an adjustable up and down previous column is located.
4. In der Säule b befindet sich eine Nuth c, in welcher sich ein innerhalb der Hülse g angebrachter und der Länge nach durchlaufender Zahn / befindet. Dieser Zahn verhindert die Drehung des Bolzens b und des Armes a h, wodurch die Einspannung der Form zwischen m und h stets in parallelen Flächen erfolgt.4. In the column b there is a groove c in which there is a tooth / which is attached inside the sleeve g and which extends lengthwise. This tooth prevents the rotation of the bolt b and the arm ah, whereby the clamping of the mold between m and h always takes place in parallel surfaces.
5. Ein Ausspringen, welches bisher durch Umschlagen der Form» vorkam, wodurch nicht selten die Blättchen zu Boden fielen, beschädigt oder selbst unbrauchbar wurden, ist beseitigt.5. A jumping out, which up to now has occurred by changing the form », whereby not seldom the leaves fell to the ground, were damaged or even became unusable, is eliminated.
6. Die Säule b mit dem Arme ah läuft in einer Hülse g, die wiederum ihre Befestigung auf dem Tische m durch ein Metallplättchen e hat, das mit zwei Schrauben / gehalten wird.6. The column b with the arm ah runs in a sleeve g, which in turn has its attachment to the table m by a metal plate e , which is held with two screws /.
7. Die Goldblätter, die oft in der Gröfse der Häutchen geschlagen sind, lassen sich bei der alten Manier r, ohne die hintere Ecke abzureifsen, nicht ausleeren; dagegen können bei dem neuen Apparat die Goldblättchen frei herausgenommen werden, was ein nicht zu unterschätzender Vortheil für Grofsgold ist.7. The gold leaves that are often beaten in the magnitude of the cuticle can be in the old style r, abzureifsen without the rear corner, not empty; on the other hand, with the new apparatus, the gold leaves can be freely removed, which is an advantage for Grofsgold that should not be underestimated.
Eine Modification der beschriebenen Spannzange stellt Fig. 6 bis 8 dar. Die Spannzange ab c d0 wird durch das Gehäuse gη und die Platte h geführt.A modification of the described collet is shown in FIGS. 6 to 8. The collet from c d0 is guided through the housing gη and the plate h .
Die Säule α b hat bei c eine Schraube mit Mutter e, welche das Anspannen der Volutfeder f gestattet.The column α b has a screw with nut e at c , which allows the volute spring f to be tightened.
Wird nun mit der linken Hand die Säule abc mit dem Arme d in die Höhe gezogen, so bewirkt die Spiralfeder f, welche ca. 12 kg Druck ausübt, dafs die Form / durch den Arm d festgespannt wird. If the column abc is now pulled up with the arm d with the left hand, the spiral spring f, which exerts about 12 kg of pressure, causes the form / to be tightened by the arm d.
Die Zange in ihrer gegenwärtigen Gestalt ist aus Eisen, Stahl und anderem Metall gefertigt.The forceps in their current form are made of iron, steel, and other metals.
