LEOPOLD KATZENSTEIN in NEW-YORK. Stopf büchsendichtung.LEOPOLD KATZENSTEIN in NEW YORK. Stuffing box seal.

Patentirt im Deutschen Reiche vom al. Dezember 1897 ab.Patented in the German Empire by al. December 1897.

Der Gegenstand der vorliegenden Erfindung bezieht sich auf Metalldichtungen, und zwar bezweckt er, eine Dichtung herzustellen, welche alle Schwingungen der unter hohem Dampfund Gasdruck stehenden Kolben- und Schieberstange aufnimmt und welche ohne irgend welche Zerlegung der Stangentheile sowie ohne grofse Zeitverschwendung eingesetzt und ebenso gut aus der Stopfbüchse herausgenommen werden kann.The subject matter of the present invention relates to metal gaskets, namely its aim is to produce a seal that will absorb all the vibrations of the high steam and Gas pressure standing piston and slide rod receives and which without any dismantling of the rod parts and without great waste of time and can be removed from the stuffing box just as easily can.

In beiliegender Zeichnung ist der Erfindungsgegenstand veranschaulicht, und zwar zeigt The subject of the invention is illustrated in the accompanying drawing, namely shows

Fig. 10 die neue Dichtung in einer mit gewöhnlichem Büchsendeckel versehenen Stopfbüchse. 10 shows the new seal in a stuffing box provided with a conventional box cover.

A ist die Kolben- oder Schieberstange, B die Stopfbüchse mit besonderem Flantsch. In Fig. ι ist ein gewöhnlicher Büchsendeckel C angeordnet, welcher vermittelst der Schrauben a mit dem Flantsch der Stopfbüchse unter Einschiebung irgend einer Packung b verbunden ist. A is the piston or slide rod, B the stuffing box with a special flange. In Fig. Ι an ordinary box cover C is arranged, which is connected by means of the screws a to the flange of the stuffing box with insertion of any package b .

Bei der in Fig. 10 gezeigten Anordnung ist ebenfalls ein Büchsendeckel C gegen die Stopfbüchse geschraubt, jedoch liegt sein Flantsch nicht direct auf jenen der Stopfbüchse auf, sondern beide befinden sich in einigem Abstand von einander.In the arrangement shown in Fig. 10, a can cover C is also against the Stuffing box screwed on, but its flange does not lie directly on that of the stuffing box but both are at some distance from each other.

Für die Anwendung der vorliegenden Dichtung ist es ganz gleich, welche Art der Verbindung der Stopfbüchse mit dem Stopfbüchsendeckel angewendet wird. Die eigentliche Abdichtung besteht aus mehreren Theilen. Die beiden Büchsenhälften sind mit einander passend verbunden. Der Theil d (Fig. 3 und 10) ist zur Aufnahme der Zwischenscheiben ρ (Fig. ι, 6 und 7) mit Rinnen d^l versehen und aufserdem sind Stifte d~ (Fig. 3) in die Rinnen eingesetzt, welche in die Zwischenscheiben eingreifen und so die Drehung der letzteren in der Büchse verhindern. Der Büchsentheil ist mit einem zweitheiligen Deckel f versehen (Fig. 1). Sowohl Büchse wie Deckel sind mit Stiften und entsprechenden Bohrungen versehen, um eine gegenseitige Bewegung zu verhindern. For the application of the present seal, it does not matter what type of connection between the stuffing box and the stuffing box cover is used. The actual seal consists of several parts. The two halves of the sleeve are connected to one another in a matching manner. The part d (Fig. 3 and 10) is provided with grooves d ^l for receiving the intermediate disks ρ (Fig. Ι, 6 and 7), and pins d ~ (Fig. 3) are inserted into the grooves, which are inserted into the intermediate disks intervene and thus prevent the latter from rotating in the sleeve. The rifle part is provided with a two-part cover f (Fig. 1). Both can and cover are provided with pins and corresponding holes to prevent mutual movement.

Die Anordnung der Dichtungsringe in derThe arrangement of the sealing rings in the

Claims

Bushing, as well as the manner in which it acts on the piston and slide rod the following:

The actual sealing ring g (Fig. 1 and 10) consists, as can be seen in the section (Fig. 2), of two rings mounted one inside the other, each of which consists of three parts (sectors) 1, 2, 3 respectively. 4, 5, 6, and both rings are so joined together that the joints of the sectors of one ring do not coincide with those of the other ring, but, as shown in Fig. 2, the joints of the outer ring 1, 2 . ^ come to lie between the joints of the inner ring 4, 5, 6, and vice versa. A pin 7 (Fig. 2) of the section 1 of the ring g occurs between the sectors 4, 5 of the inner ring and thus prevents the rotation of the latter in the outer ring.

These parts forming the seal, just described, are, in order to firmly enclose the piston or slide rod A , spanned with an endless spiral spring II (FIGS. 1 and 10). The best way of connecting the ends of this coil spring / 2 is shown in Fig. 9, with a small coil spring piece / 'connected to the ends of the spring h . However, any other type of connection of the spring ends can also be used.

A pad j (Fig. 1) in the form of a band is inserted between the spring and the sealing ring, which is made of soft metal, in order to prevent the spiral spring h from cutting into the metal. This insert also prevents steam from penetrating between the individual rings.

The rings gk I and m are completely identical to one another, with the exception of one side of the rings / and m, which, as shown in FIG. 1, are bevelled to accommodate a pressure ring η. To the latter, • the pressure ring has η specifies the coil spring to press 0. m laterally from each other the purpose of the rings Z and; so that the whole ring system is zusammengeprefst.

The intermediate disks ρ , which consist of two parts and are inserted between the sealing rings g 1 and km , are provided with a recess q (Fig. 7) into which one of the pins d ¹ (Fig. 3) enters and so, as already said, one Displacement or rotation of the discs on the piston or slide rod is avoided. The grommets have ρ in the Nuthen ^l d of d Stopfbüchsentheils a small clearance. Once <mn of the pressure ring is pressed η, egg 'the seal rings sliding sideways, namely the rings / and m against the washers ρ ρ back and this g slowly against the seal rings and k; so that Sämmtliche in this way while working vibrations of Piston or slide rod are added.

If the pressure ring η is to be omitted, there is no need for clearance in the grooves d ^l for the washers ρ . Behind the last ring, between this and the cover C respectively. C ¹ secondary rings made of soft metal are also arranged. In the drawing (Fig. 1 and 10) a two-part beveled ring r made of white metal (Fig. 4 and 5) and a second ring s (Fig. 1, 8 and 10) are indicated, the latter of which on the wall of the stuffing box rests and the ends of the inclined ring r receives, the former, on the other hand, is intended to receive the ends of the conical stuffing box cover f .

Patent-Α ν Proverbs:

ι. Stuffing box seal, characterized by two sets of split rings g I and A-MZ, each set of which consists of split rings arranged one inside the other, in such a way that the parts of both sets are separated simultaneously in the direction of the rod by the steam pressure , but are enclosed by a resilient band or a helical spring h in order to secure the seal in a known manner.

2. Embodiment of the stuffing box seal identified in claim 1, in which between two rings provided with beveled edges / m a V-shaped cross-section, surrounded by a helical spring ο, pressure ring η is placed, which pulls the divided rings against the housing end faces pushes each other.
