Description
Durch Patent 8o2 9oi ist eine Verbindung für Luttenenden bekanntgeworden, bestehend aus einem Blechband. das mit Wülsten in konforme Wulstringe der Lutten eingreift und mit einem Filzstreifen den Stoß der Luttenenden ülserdeckt. Die Besonderheit jener Verbindung besteht darin, daß auf dem Blechband quer zwei Paare von seinen En(len fortgebogene Krampen angeordnet sind. Das Außenpaar dieser Krampen dient zur vorübergehenden Aufnahme einer Schraubzwinge, die das Blechband zusammenzieht. Das Innenpaar der Krampen dient zum Verschluß durch ein aufgeschohenes Keilschloß.A connection for duct ends has become known through patent 8o2 9oi, consisting of a sheet metal strip. that with beads in conformal bead rings of the ducts engages and covers the joint of the duct ends with a felt strip. The peculiarity that connection consists in the fact that two pairs of his En (len bent staples are arranged. The outer pair of these staples is used For the temporary inclusion of a screw clamp that pulls the sheet metal strip together. The inner pair of staples is used to close with an open wedge lock.
Diese Verbindung wird dadurch befestigt, daß die Schraubzwinge auf das äußere Paar aufgesetzt wird und durch Andrehen das Blechband so weit zusammenzieht, daß das Keilschloß auf die entsprechenden, nahe aneinander geführten Innenkrampen aufgeschoben und dort durch Schlag, mit einem Hammer oder dergleichen in seinen richtigen Sitz gebracht werden kann.This connection is secured by opening the screw clamp the outer pair is put on and by turning pulls the sheet metal strip together so far, that the wedge lock on the corresponding, closely led inner clamps postponed and there by blow, with a hammer or the like in his correct fit can be brought.
Diese Verbindung setzt daher voraus, daß der Bergmann in seinem Gezähekasten eine Schraubzwinge mit sich führt, die dem Sonderzweck dient, diese Luttenenden miteinander zu verbinden. Dies wird als ein Nachteil der all sich recht brauchbaren Verbindung angesehen.This connection therefore presupposes that the miner is in his tack box carries a screw clamp with it, which serves the special purpose, these pipe ends to connect with each other. This is considered to be a disadvantage of all of them being quite usable Connection viewed.
Hier setzt die Erfindung ein. Sie besteht darin, daß das Blechband für die Verbindung durch entsprechende Vorbehandlung mit Spannung nach innen ausgebildet ist, so daß es sich bereitwillig in die Verschlußstellung an die Luttenenden legen läßt. Ferner sind auf (lern derart vorbehandelten Blechband nur noch zwei von seinen Enden fortgebogene Krampen angeordnet. Diese liegen sehr nahe an den Stoßkanten des Blechbandes. Das bisher notwendige zweite Paar Krampen, welches außenliegend zur :\ufnahme einer Schraubzwinge dient, ist fortgefallen, ebenso wie die Schraubzwinge selbst. Der Fortfall der außenliegenden Krampen vereinfacht das Blechband entsprechend, während der Fortfall der Schraubzwinge praktisch eine erhebliche Bedeutung hat.This is where the invention comes in. It consists in the sheet metal strip designed for the connection by appropriate pretreatment with tension inwards is so that it willingly put itself in the closed position on the ends of the duct leaves. Furthermore, only two of his Ends bent staples arranged. These are very close to the abutting edges of the sheet metal strip. The previously necessary second pair of staples, the one on the outside is used to hold a screw clamp has been omitted, as has the screw clamp itself. The elimination of the external staples simplifies the sheet metal strip accordingly, while the elimination of the screw clamp is of considerable practical importance.
Nunmehr dient zum Zusammenziehen und zum `'erscliluß des Blechbandes nur noch einKeilschloß. Dieses Keilschloß ist wesentlich enger als bisher üblich, seine Keilform ist schlanker. Vorteilhaft,ist, daß (las Keilschloß ein wenig nach außen gewölbt ist, so (laß es eine gewisse, wenn auch nur geringe I-'e(lerl:i-aft hat. Die Krampen sind konisch ausgebildet. Ihre Keilform entspricht derjenigen des aufgeschobenen Keilschlosses. Für die Praxis des 13ergbaties hat sich ergeben, daß die etwas größere t,nd auch etwas dickere Ausbildung des Keilschlosses vorteilhaft ist, weil man auf diese Weise das Keilschloß unter Tage deutlicher erkennt und leichter 'handhaben kann.Now serves to pull together and to close the sheet metal strip just a wedge lock. This wedge lock is much tighter than usual, its wedge shape is slimmer. It is advantageous that (read the wedge lock a little is arched on the outside, so (let it be a certain, if only slight, I-'e (lerl: i-aft Has. The staples are conical. Their wedge shape corresponds to that of the postponed wedge lock. For the practice of the 13ergbaties it has emerged that the somewhat larger t, nd also somewhat thicker design of the wedge lock is advantageous is because in this way the wedge lock can be seen more clearly and more easily underground 'can handle.
Die neue Verbindung für Luttenenden besteht also darin, daß an einem mit Spannung nach innen ausgebildeten Blechband quer, nahe der Berührungskanten ein Paar von den Enden fortgebogene Krampen angeordnet ist, deren Kanten keilförmig zur Aufnahme eines entsprechend konischen Keilschlosses ausgebildet sind. Nach einer Verbesserung der Erfindung ist das Keilschloß in seinem Oberteil gewölbt und in der Querrichtung ein wenig federnd.The new connection for pipe ends is that on one with tension inwards formed sheet metal strip transversely, near the contact edges a pair of staples bent away from the ends is arranged, the edges of which are wedge-shaped are designed to accommodate a correspondingly conical wedge lock. After a Improvement of the invention, the wedge lock is arched in its upper part and in the transverse direction a little springy.
Die neue Erfindung ist in der Zeichnung schaubildlich dargestellt. \-Ian erkennt, daß auf den Luttenenden i und 2 ein Verbindungsband 3 angeordnet ist. Dies trägt in der Nähe seiner Stoßkanten ,4 Blechformstücke 3 und 6, deren vordere Enden von den Stoßstellen fortgebogene Krampen; und 8 tragen. Ersichtlich verlaufen diese Krampen keilförmig. Ihr Abstand ist an der linken Seitenkante weiter als an der rechten. Entsprechend keilförmig ist das Keilschloß q ausgebildet. Es ist ferner zu erkennen, daß der Steg io zu den Keilflanken dieses Schlosses aufwärts gewölbt ausgebildet ist. Hierdurch besteht eine gewisse Federkraft.The new invention is shown diagrammatically in the drawing. \ -Ian recognizes that a connecting band 3 is arranged on the duct ends i and 2 is. This carries in the vicinity of its abutting edges, 4 sheet metal fittings 3 and 6, their front ends bent away from the joints; and 8 wear. Obvious these cramps run in a wedge shape. Their distance is wider on the left side edge than on the right. The wedge lock q is correspondingly wedge-shaped. It it can also be seen that the web io up to the wedge flanks of this lock is arched. This creates a certain spring force.
Sollen zwei Luttenenden i ttnd 2 miteinander verbunden werden, so wird ein Band 3 aufgelegt, zu dessen Andichtung der innett vertiefte Mittelteil dient. Zusätzlich dichtet dies Band auch deshalb an, weil es mit Spannung nach innen ausgebildet ist. Die Krampen 7 und 8 stellen in bequemer Lage einander gegenüber, so (laß infolge der starken Keilform und Länge der Krampen ohne weiteres sichtbar ist, in welche Richtung der Keil 9 aufgeschoben -,werden muß. 1-eicht ersichtlich ist in der Abbildung, daß die Breite des Keilschlosses am linken Ende ungefähr doppelt so groß ist wie der Abstand der tiefsten Krampenstellen voneinander auf der rechten Seite des zu befestigenden Bandes.If two duct ends i ttnd 2 are to be connected to one another, so a tape 3 is placed, to seal the innett recessed middle part serves. In addition, this tape also seals because it is tensioned inwards is trained. The staples 7 and 8 are conveniently opposite each other, so (because of the strong wedge shape and length of the staples, make it readily visible is the direction in which the wedge 9 is pushed - must be. 1-not visible is in the figure that the width of the wedge lock at the left end is approximately double is as great as the distance between the deepest cramp spots on the right Side of the tape to be attached.
Mit Hilfe des neuen Bandes und seines Verschlusses wird die Verbindung von L uttenenden wesentlich vereinfacht.With the help of the new strap and its fastener, the connection is made considerably simplified of ring ends.
