Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei der unter Nr. 86157 geschützten Einrichtung wird die selbstthätige Ausschalung von Formsteinen durch federnde Formen bewirkt, die nach Entfernung des Rahmens in ihre ursprüngliche Form zurückgehen. Hierbei müssen die Formen sowohl beim Ein- als auch beim Ausschalen einzeln in die Hand genommen werden. Eine Verbesserung läfst sich dadurch erzielen, dafs man die Formen in mehr oder weniger grofser Zahl an einander hängt, wie in Fig. 5a und 5b angegeben ist, wo durch wellenförmige Biegung eines Metallstreifens eine Anzahl Formzellen gebildet werden, die zur einen Hälfte rechts, zur anderen links liegen. Die Stege 5 s der Wellen sind durchweg geradlinig angenommen; sie bilden mit den Rückenflächen r r rechte Winkel. Diese Rückenflächen aber können so gebogen sein, dafs sie beim Strecken federn (Fig. 5a), oder sie können geradlinig sein (Fig. 5b), so dafs .sie beim Durchbiegen federn. Werden im ersten Fall (Fig. 5 a) die Enden so weit zusammengedrückt, bis die Stege s s einander parallel sind, so haben die gekrümmten Rückwände r r sich wieder in eine Ebene eingestellt. Man kann in einem entsprechend grofsen Rahmen mehrere Zellenbleche zu einer Gruppe zusammenfassen (Fig. ia). Die Füllung und Ausschalung der Formen erfolgt im Falle der Fig. 5a in ähnlicher Weise, wie im Haupt-Patent angegeben. ImFaIIe der Fig. 5b sind Griffe X nöthig, an denen die Wellen nach Entfernung des Formrahmens harmonikaartig aus einander gezogen werden.In the case of the device protected under No. 86157, the automatic stripping of shaped stones is effected by resilient forms that return to their original shape after the frame has been removed. The molds have to be picked up individually both during shuttering and stripping. An improvement can be achieved by hanging the shapes on one another in more or less large numbers, as is shown in FIGS others are on the left. The ridges 5 s of the waves are assumed to be straight throughout; they form with the back surfaces rr right angles. These back surfaces, however, can be curved in such a way that they spring when they are stretched (Fig. 5a), or they can be straight (Fig. 5b) so that they spring when they are bent. If in the first case (FIG. 5 a) the ends are pressed together until the webs ss are parallel to one another, the curved rear walls rr have returned to one plane. Several cell panels can be combined into a group in a correspondingly large frame (Fig. Ia). The filling and stripping of the molds takes place in the case of FIG. 5a in a manner similar to that indicated in the main patent. In the case of FIG. 5b, handles X are required, by which the waves can be pulled apart like a harmonica after the shaped frame has been removed.
Die geformten Körper lösen sich hierdurch nicht allein von den Stegen ab, sondern werden auch von den Rückwänden des Formbleches, die sich dabei leicht krümmen, bei Seite geschoben.As a result, the shaped bodies are not only detached from the webs, but become also from the back walls of the shaped sheet, which bend slightly in the process Side pushed.
Um diese Vorrichtung bei Herstellung von Steinen aus langsam abbindendem Rohmaterial zu benutzen, wird zweckmäfsig die in Fig. 5b angegebene Form benutzt.Around this device when making stones from slowly setting raw material to use, the form indicated in Fig. 5b is expediently used.
An die Zellenwände der Formen werden leicht auswärts federnde Blechfutter b gelegt (Fig. ib, 2b, 3b, 4b und 5b), die das Insichzusammenfallen der eingegossenen und noch nicht abgebundenen Formsteine nach Entfernung der Zellenbleche verhüten. Die Abnahme dieser Blechfutter erfolgt, sobald die Steine genügend erhärtet sind. Slightly outwardly resilient sheet metal chucks b are placed on the cell walls of the molds (Fig. 1b, 2b, 3b, 4b and 5b), which prevent the cast and not yet hardened shaped stones from collapsing after the cell sheets have been removed. This sheet metal lining is removed as soon as the stones have hardened sufficiently.
