In der Gelenkbänderfabrikation ist es bekanntlich erforderlich, die sichtbar bleibenden Theile des Gelenkbandes (einer Fitsche), das sind der Rücken der Dornhülse und die Knöpfe, blank zu bearbeiten, um dadurch ein besseres Haften der Farbe auf denselben zu ermöglichen. Nun erfordert aber gerade das Schleifen des Rückens der Dornhülse viele geübte und deshalb auch theure Arbeitskräfte, so dafs gerade hierdurch der Herstellungspreis der Thürenbänder bedeutend erhöht wird.In the manufacture of wrist ligaments, it is well known that those that remain visible are necessary Parts of the ligament (a Fitsche), that is the back of the thorn sleeve and the buttons, to be processed blank in order to enable the paint to adhere better to the same. But the grinding of the back of the mandrel sleeve requires a lot of practiced and therefore also expensive labor, so that precisely because of this the production price of the door hinges is increased significantly.

Vorliegende Erfindung bezweckt nun, eine Maschine zu schaffen, die diese Arbeit vollständig selbsttätig verrichtet und die zu ihrer Bedienung nur einer sehr billigen Arbeitskraft bedarf.The present invention now aims to provide a machine that can do this job completely done automatically and only a very cheap worker to operate them requirement.

Dieser Zweck wird erreicht durch die auf beiliegender Zeichnung dargestellte Maschine. Es ist:This purpose is achieved by the machine shown in the accompanying drawing. It is:

Die wesentlichen Theile der Maschine sind auf und unter einer Tischplatte A montirt, welche in der Mitte mit einem fast ganz durchgehenden Längsschlitz B von ziemlicher Breite versehen ist.The essential parts of the machine are mounted on and under a table top A , which is provided in the middle with an almost completely continuous longitudinal slot B of considerable width.

Dieser Schlitz B wird nach oben durch zwei auf dem Tisch A befestigte Platten C fast vollständig abgedeckt, so dafs diese nur einen schmalen Schlitz D zwischen sich lassen. In diesen Schlitz D werden die zu schleifenden Fitschen hineingelegt, und zwar so, dafs die Hülse oberhalb des Tisches gehalten ist, der Lappen aber in den Schlitz B frei hinabhängt. Die Platten C sind auf der Tischplatte A einstellbar so befestigt, dafs der Schlitz D immer der Dicke des Fitschenlappens entsprechend verbreitert oder verengt werden kann.This slot B is almost completely covered at the top by two plates C fastened to the table A , so that these only leave a narrow slot D between them. The slits to be ground are placed in this slot D in such a way that the sleeve is held above the table, but the cloth hangs freely down into the slot B. The plates C are adjustably attached to the table top A in such a way that the slot D can always be widened or narrowed according to the thickness of the flap.

In dem Schlitz B bewegt sich eine Gelenkkette ohne Ende E, die über zwei Kettenräder .Fund F¹ läuft, deren Achsen G und G¹ je an einem Ende des Tisches A gelagert sind. Die Achse G ist fest gelagert und vermittelst Schneckenrades und Schnecke von der Hauptantriebswelle H aus angetrieben. Die Achse G¹ kann aber mittelst in Schwalbenschwanzführung gehaltener Lager in der Tischplatte A verstellt werden, um so die Kette E nach Bedarf anspannen zu können.In the slot B moves a link chain without end E, which runs over two chain wheels .Fund F ¹ , the axes G and G ^{1 are} each mounted at one end of the table A. The axis G is firmly mounted and driven by the main drive shaft H by means of a worm wheel and worm. The axis G ¹ can, however, be adjusted by means of bearings held in a dovetail guide in the table top A in order to be able to tighten the chain E as required.

Die Kette E unterscheidet sich von einer gewöhnlichen Gelenkkette dadurch, dafs die äufseren Platten nach oben hin einen Ansatz J haben mit Bohrung zum Durchstecken eines Bolzens K, der an einer Seite einen verlängerten Kopf L besitzt.The chain E differs from an ordinary articulated chain in that the outer plates have an extension J at the top with a hole for inserting a bolt K, which has an elongated head L on one side.

Die beschriebene Lagerung der Kettenräder mit ihren Achsen ist nun so getroffen, dafs bei der Bewegung der Kette E durch den Schlitz B der Kopf L des Bolzens K inThe described mounting of the chain wheels with their axes is such that when the chain E moves through the slot B, the head L of the bolt K in

at a suitable distance from the plates C along under the slot D, so that when the chain is moved, the fitsche inserted in the slot D is pushed away from the head L , the sleeve sliding on the table.

The bolts can of course always be in the chain at a distance corresponding to the relevant Fitschen length can be used.

The following con 'now acts on the mandrel sleeve sliding along the table struirte and shown in Fig. 4 a grinding device.

Screwed to a semi-circular, on the table A bracket M is screwed at an inclination of about 45 ⁰ to the horizontal, a storage rack N, but so, that this angle may be varies, for which purpose at both sides in the bracket M, a slit O is provided so that the frame N can be attached to the right or left as required.

An axis P with an emery disk Q seated on it is mounted in this storage rack and is set in rotation by means of the drive disk R from a special transmission.

This grinding device is mounted on table A in such a way that the rotating emery disk, which has an edge shaped to match the curvature of the Fitschen sleeve, grinds one side of the back of the sleeve as the Fitsche moves through the table, so that the disk is always slightly above the Reaches over the middle of the back of the case (Fig. 4)

The bearing shells of the axis P are adjustable in the frame N by means of screws S and are elastically fastened by means of springs T , the former to be able to readjust the emery disk according to the wear, the latter to avoid excessive wear in the event of any unevenness on the Fitschenhülsen to be ground .

Two such grinding devices are arranged on the table top in such a way that one of them grinds the Fitsche from the right and the other from the left. In order to be able to mount these parts on the plate A , openings U and U ^{1 are} provided in the same, into which one side of the storage rack engages.

The way this machine works is self evident from the description above.

At one end of the machine, the pockets are inserted into the slot D by hand. Then the machine automatically transports them in the slot D along to the other end of the machine by means of the chain E. In this way the backs of the fitschenhülsen are first sanded on the linen side by a rotating emery disc and then on the other by a second. Since the two sanding disks always reach over the middle of the back of the case, a shoulder cannot be sanded here.

So they arrive at the other end of the machine, sanded smooth, and fall there out automatically into a container placed underneath.
