Stahlhalter. Patentiert im Deutschen Reiche vom 26. Februar 1924 ab. Steel holder. Patented in the German Empire on February 26, 1924.

Durch das viele Arbeiten mit dem Plantransport beim An- und. Abstellen des Werkzeuges bekommen Spindel und Mutter durch ihre Abnutzung toten Gang. Dieser macht sich bei Toleranzarbeiten unliebsam bemerkbar, ganz besonders beim Gewindeschneiden; ein Schnitt wird gut, der zweite versagt, der dritte reißt den zweiten nicht geschnittenen Schnitt oder Span gleich mit heraus. Nur durch die größte Aufmerksamkeit des Drehers wird das Arbeitsstück nicht Ausschuß. Diesen Übelstand beseitigt der Erfindungsgegenstand, der wie jeder Bohr- und Gewindestahl auf dem Support befestigt wird.Because of all the work with the plan transport on arrival and. Parking the tool spindle and nut get dead gear due to their wear and tear. This is noticeable in tolerance work, especially when thread cutting; one cut is good, the second fails, the the third tears out the second uncut cut or chip at the same time. Just if the lathe operator takes the greatest care, the workpiece will not be rejected. This problem is eliminated by the subject of the invention, which, like every drill and thread steel, is attached to the support will.

Auf der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes dargestellt. Es zeigen: Abb. ι eine Vorderansicht, Abb. 2 eine Seitenansicht,The drawing shows an example of an embodiment of the subject matter of the invention shown. They show: Fig. Ι a front view, Fig. 2 a side view,

Abb. 3 einen Grundriß des Erfindungsgegenstandes, Fig. 3 is a floor plan of the subject of the invention,

Abb. 4 einen Schnitt durch ihn und Abb. S und 6 den Schaltungshebel in verschiedenen Stellungen bei an- und abgestelltem Stahl.Fig. 4 a section through him and Fig. S and 6 the shift lever in different Positions with the steel on and off.

Der Apparat besteht aus dem Stahlhaltergehäuse a, der Spindel b, Bohrstange c, Schaltungshebel d, den Anschlagstiften e1 und e" sowie den Stellmuttern /.
Der Hebel d wird bis zu dem Anschlag e1 hochgestellt, der Support in seinen Leisten so angezogen, daß er sich gerade noch bequem kurbeln läßt, und dann der erste Schnitt angestellt und durchgeschnitten. Anstatt nun
The apparatus consists of the steel holder housing a, the spindle b, boring bar c, shift lever d, the stop pins e 1 and e " and the adjusting nuts /.
The lever d is raised up to the stop e 1 , the support is tightened in its strips so that it can just be cranked comfortably, and then the first cut is made and cut. Instead of now

ίο den Support abzukurbeln, was unter allen Umständen zu unterlassen ist, legt der Dreher den Hebel ei um bis zum Anschlag e2, und der Stahl critt vom Arbeitsstück so reichlich zurück, daß während des Zurücklaufens des Supports schon der neue Span angestellt werden kann, was sehr zeitsparend ist. Die Spindel b macht hierbei eine Viertelumdrehung um ihre Achse. Es gibt demnach kein Zurückkurbeln mehr und wird auch kein toter Gang erzeugt. Der «o E reher arbeitet sicherer, schneller und bequemer; Spindel und Mutter sind immer in gespannter Stellung. Der ganze Arbeitsprozeß erleichtert sich. Ist ein Arbeitsstück naeh dem Fertigbohren gleich zu schneiden, braucht man die kleine Bohrstange nur auszuwechseln und durch die Bohrstange mit · dem Gewindestahl zu ersetzen, oder es wird nur das eine Werkzeug gegen ein anderes ausgetauscht.ίο to crank the support, which is to be omitted under all circumstances, the turner turns the lever ei to the stop e 2 , and the steel crits back from the workpiece so abundantly that the new chip can be made while the support is running back, which is very time-saving. The spindle b makes a quarter turn around its axis. There is therefore no more cranking back and no dead gear is generated. The E reher works safer, faster, and more conveniently; The spindle and nut are always in a tensioned position. The whole work process is made easier. If a work piece is to be cut in the same way as the finish boring, the small boring bar only needs to be exchanged and replaced by the boring bar with the thread bar, or just one tool is exchanged for another.
