KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine neue Anordnung an solchen Getrieben, die aus einer feststehenden, mit Rechts- und Linksgewinde versehenen Hülse und .darin verschiebbarem, mit Gewindegang oder Zapfen versehenem Cylinder bestehen und zur Umwandlung einer Drehbewegung in eine hin- und hergehende Bewegung dienen.The invention is a new arrangement of such transmissions, which from a fixed sleeve with a right and left thread and a sliding sleeve exist with a thread or pin provided cylinder and to convert a Rotary motion serve in a reciprocating motion.
Fig. ι der beiliegenden Zeichnung zeigt die Vorrichtung im Schnitt mit abgelöstem Deckel und herausgezogenem Bolzen, während Fig. 2 einen Grundrifs des Bolzens in kleinerem Mafsstabe darstellt.Fig. Ι of the accompanying drawing shows the device in section with the cover removed and pulled out bolt, while FIG. 2 shows a basic outline of the bolt on a smaller scale represents.
In der mit Deckel α und Boden b versehenen feststellbaren, mit sich kreuzenden rechts- und linksgängigen Muttergewinden versehenen Hülse c ist ein Bolzen oder Cylinder d angeordnet, auf dessen Umfang ein in das Muttergewinde passender Ring/ sitzt. Letzterer besteht aus zwei Theilen, von denen jeder um. einen Zapfen g drehbar ist, die in entsprechend der Steigung des" Muttergewindes versetzten Löchern des Cylinders stecken.In the lockable sleeve c provided with cover α and base b and provided with intersecting right-hand and left-hand threading threads, a bolt or cylinder d is arranged, on the circumference of which a ring / is seated that fits into the nut thread. The latter consists of two parts, each of which is around. a pin g is rotatable, which are inserted into holes of the cylinder which are offset according to the pitch of the "nut thread".
Die Achse h des Cylinders d trägt eine auf ihr verschiebbare, aber nicht drehbare Riemscheibe oder ein Zahnrad, das auf der Zeichnung weggelassen ist und mittelst dessen der Cylinder in Umdrehung versetzt werden kann. Geschieht dieses im Sinne des Uhrzeigers, so nehmen die beweglichen Ringstücke f die auf der Zeichnung dargestellte Stellung ein, bei welcher der Bolzen in die Hülse hineingeschraubt wird, sich also nach abwärts bewegt. Ist der vordere Ringtheil am Boden der Hülse angekommen, so wird derselbe beim weiteren Vorschieben des Bolzens durch den Boden der Hülse zu einer Drehung um den Zapfen g veranlafst, bei welcher er in den linksgängigen Gewindegang tritt und nunmehr den Bolzen trotz der Drehung desselben im gleichen Drehungssinne nach oben, also zurückbewegt, und zwar so lange, bis der vordere Ringtheil am Deckel der Hülse angelangt ist, wo die Umkehrung des Getriebes in derselben Weise, wie am Boden, erfolgt.The axis h of the cylinder d carries a pulley or a toothed wheel which can be displaced on it, but which cannot be rotated, and which has been omitted in the drawing and by means of which the cylinder can be set in rotation. If this happens clockwise, the movable ring pieces f assume the position shown in the drawing, in which the bolt is screwed into the sleeve, ie moves downwards. If the front part of the ring has reached the bottom of the sleeve, it is caused to rotate around the pin g when the bolt is further advanced through the bottom of the sleeve, in which it enters the left-hand thread and now the bolt in spite of the rotation of the same Direction of rotation upwards, that is, moved back, until the front part of the ring has reached the cover of the case, where the gear is reversed in the same way as on the bottom.
Genau wie bei der vorbeschriebenen Rechtsdrehung des Cylinders ist die Arbeitsweise beim Linksdrehen, nur dafs dann' die Ringstücke durch das linksgängige Gewinde in die Hülse hineingeschraubt und durch das rechtsgängige Gewinde aus der Hülse herausgeschraubt werden.The mode of operation is exactly the same as with the clockwise rotation of the cylinder described above when turning to the left, only then 'the ring pieces through the left-hand thread into the Sleeve screwed in and screwed out of the sleeve through the right-hand thread will.
