PATENTAMT.PATENT OFFICE.
Die Herstellung von faconnirten, am Rande abgeschliffenen, facettirten Spiegeln wurde bisher hauptsächlich von Hand vorgenommen, während mit vorliegender Copirfacettirmaschine derartige Spiegel automatisch hergestellt werden sollen.The production of faceted mirrors, ground on the edge, facetted mirrors has hitherto been used mainly done by hand, while with the present Copirfacettirmaschine such Mirrors are to be produced automatically.
Die Facettirmaschine besteht aus einem Fundamentrahmen F, welcher einen Klemmbügel K trägt. In diesem ist das in einen Cylinder H auslaufende Querstück Q drehbar befestigt, in dessen' verticaler Bohrung der Support S mit seinem cylindrischen Ansatz verschiebbar angeordnet ist.The faceting machine consists of a foundation frame F, which carries a clamping bracket K. In this the cross piece Q running out into a cylinder H is rotatably fastened, in the vertical bore of which the support S with its cylindrical extension is displaceably arranged.
Dieser bildet die Lagerung für die Welle W mit Schnecke J, die eine darüber lagernde Querwelle W1 mittelst des Schneckenrades S1 in langsame Drehung versetzt, sobald die Welle W durch das Kettenrad K1 und Kette von einem auf der Schleifsteinwelle sitzenden Kettenrad K2 angetrieben wird. Die Welle W1 trägt ferner eine auswechselbare Schablone L beliebiger Form, in vorliegendem Falle oval angenommen, welche durch eine Büchse mit dem Schneckenrad S1" fest verbunden, aber auswechselbar ist.This forms the bearing for the shaft W with worm J, which sets an overlying cross shaft W 1 into slow rotation by means of the worm wheel S 1 as soon as the shaft W is driven by the chain wheel K 1 and chain from a chain wheel K 2 sitting on the grindstone shaft will. The shaft W 1 also carries an exchangeable template L of any shape, assumed to be oval in the present case, which is firmly connected to the worm wheel S 1 ″ by a bushing, but is exchangeable.
Diese Schablone steht mit der Führungsrolle R in Berührung, welche in einem mit Gewinde versehenen einstellbaren Bügel B befestigt ist, der seine Lagerung ebenfalls in dem Querstück Q besitzt, so dafs bei Drehung des Apparates um die Hülse H die Function der Schablone unbeeinflufst bleibt.This template is in contact with the guide roller R , which is fastened in an adjustable bracket B provided with a thread, which is also mounted in the crosspiece Q, so that when the apparatus is rotated around the sleeve H, the function of the template remains unaffected.
Diese besteht darin, dafs die Drehung der Welle W1 unter Einwirkung dieser Schablone L den Support S heben und senken kann, so dafs die Form der Schablone L für den Gang des Glases G, welches mittelst der Einspannvorrichtung E mit der Welle W1 verbunden ist, mafsgebend ist bezw. ein regelrechtes Copiren eintritt.This consists in the fact that the rotation of the shaft W 1 under the action of this template L can raise and lower the support S , so that the shape of the template L for the passage of the glass G, which is connected to the shaft W 1 by means of the clamping device E , mafsgend is resp. a proper copying occurs.
Die zum Einspannen des Glases G dienende Vorrichtung E besteht, wie aus Fig. 1 und 5 ersichtlich, aus einem sechsarmigen Stern, dessen einzelne Arme runden Querschnitt zeigen und an welchem die Klauen M verschiebbar gelagert sind und mittelst der Stellschrauben L und Keile 6 in jeder beliebigen Lage festgehalten werden können.The device E used to clamp the glass G consists, as can be seen from FIGS. 1 and 5, of a six-armed star, the individual arms of which show a round cross-section and on which the claws M are slidably mounted and by means of the adjusting screws L and wedges 6 in each can be held in any position.
Die Klauen M sowohl, als auch die mittlere Nabe N sind mit Gummi belegt, um eine weiche Lagerung des Glases, welches mittelst der Feder F von aufsen angedrückt wird, zu gestatten.The claws M as well as the central hub N are covered with rubber in order to allow a soft mounting of the glass, which is pressed on from the outside by means of the spring F.
Das Schneckenrad S1 ist auf der Welle W1 nicht fest, sondern mittelst Nuth und Feder befestigt, so dafs letztere durch die einstellbare Druckvorrichtung D und Gegengewicht C mit der Einspannvorrichtung E und dem Glas G vorwärts bewegt und das Glas beliebig stark an den Schleifstein angeprefst werden kann.The worm wheel S 1 is not fixed on the shaft W 1 , but is fastened by means of a keyway and spring, so that the latter is moved forward by the adjustable pressure device D and counterweight C with the clamping device E and the glass G and the glass is pressed against the grindstone as much as desired can be.
Behufs Einstellung der Facettenschräge ist, wie schon oben erwähnt, der ganze Apparat mit dem Querstück Q. und der Hülse H in dem Klemmbügel K drehbar angeordnet.As already mentioned above, the entire apparatus with the crosspiece Q. and the sleeve H is rotatably arranged in the clamping bracket K for the purpose of setting the bevel of the facet.
Der Schleifstein J1 , welcher laut Zeichnung rechtwinkelig zur Glasebene bewegt wird, kann auch irgendeine andere Drehrichtung bezw. Lagerung erhalten, in welchem Falle der Antrieb der Welle W nicht direct von der Schleifsteinachse, sondern von einem Vorgelege aus erfolgt.The grindstone J 1 , which is moved at right angles to the plane of the glass according to the drawing, can BEZW any other direction of rotation. Storage received, in which case the drive of the shaft W does not take place directly from the grindstone axis, but from a back gear.
Die Arbeitsweise geschieht wie folgt: Angenommen, ein ovales Glas gelange zur Bearbeitung, so wird dasselbe mittelst der Einspann-The procedure is as follows: Assuming an oval glass is processed, so the same is achieved by means of the
vorrichtung E, Fig. ι, an dem Apparat derartig befestigt, dafs seine Achsen sich genau mit denjenigen der ovalen Schablone L decken.Device E, Fig. ι, attached to the apparatus in such a way that its axes coincide exactly with those of the oval template L.
Diese Befestigung geschieht vermittelst der an dem sechsarmigen Stern befindlichen Klauen M mit Gummiauflage und der Feder F, welche mittelst Bügelschraube von vorn das Glas anprefst. This fastening is done by means of the claw M with rubber pad on the six-armed star and the spring F, which presses the glass from the front by means of a U-bolt.
Sobald nun mittelst der Riemscheibe der Schleifstein in Rotation gebracht wird, überträgt sich dessen Drehung durch die Kettenrollen K und Kx , Welle' W, Schnecke J und Schneckenrad S1 auf die Welle Wj, welche nun das Glas in eine langsame, rotirende Bewegung versetzt.As soon as the grinding stone is brought into rotation by means of the pulley, its rotation is transmitted through the chain rollers K and K x , shaft ' W, worm J and worm wheel S 1 to the shaft Wj, which now sets the glass in a slow, rotating motion .
Gleichzeitig bewegt sie aber auch die ovale Schablone L, welche sich auf der Rolle R führt, so dafs ein Heben und Senken des Supports S nebst seinem cylindrischen Ansatz in dem Querstück Q erfolgt (Fig. 4).At the same time, however, it also moves the oval template L, which is guided on the roller R , so that the support S is raised and lowered along with its cylindrical attachment in the crosspiece Q (FIG. 4).
Es gelangen daher alle Punkte des unrunden, in vorliegendem Falle ovalen Glases gleichmäfsig zur Anlage an den Schleifstein, wobei sie durch die Druckvorrichtung D mit den Schrauben D1 und D2 und das Gegengewicht C beliebig stark angeprefst werden.Therefore, all points of the non-round, in the present case oval, glass come to rest evenly on the grindstone, whereby they can be pressed as hard as desired by the pressure device D with the screws D 1 and D 2 and the counterweight C.
Die gewünschte Tiefe der Facette wird durch Einstellung der Stellschraube D2 erzielt. Um eine bestimmte Facettenschräge zu erhalten, hat man nur nöthig, das Querstück Q mittelst der Hülse H in dem Klemmbügel K beliebig vor- oder rückwärts geneigt einzustellen.The desired depth of the facet is achieved by adjusting the adjusting screw D 2 . In order to obtain a certain bevel of the facet, it is only necessary to adjust the crosspiece Q by means of the sleeve H in the clamping bracket K at any angle forwards or backwards.
Je nach der Gröfse der Gläser, welche im Falle der concentrischen Form alle mit der gleichen Schablone bearbeitet werden können, stellt man die Rolle R mittelst des mit Gewinde versehenen Bügels B beliebig hoch oder tief ein.Depending on the size of the glasses, which in the case of the concentric shape can all be processed with the same template, the roller R can be set as high or low as desired by means of the threaded bracket B.
