Säulengestell für kinematographische Vorführungsapparate.Column frame for cinematographic demonstration apparatus.

Patentiert im Deutschen Reiche vom 15. April 1924 ab.Patented in the German Empire on April 15, 1924.

Die bekannten Säulengestelle für kinematographische Vorführungsapparate bestehen meistejis aus einem oder zwei Gußstücken, wobei gewöhnlich der Fuß des Gestelles und die Säule aus einem Stück gegossen sind.Most of the known pedestals for cinematographic projection apparatus exist from one or two castings, usually the base of the frame and the column are cast in one piece.

Diese Konstruktion hat den Nachteil, daß das Gewicht des Gestelles erheblich wird, weil bekanntlich bei Herstellung von Gußstücken aus Festigkeitsgründen wie auch aus hüttentechnischen Gründen unter eine gewisseThis construction has the disadvantage that the weight of the frame is considerable, because as is well known in the production of castings for reasons of strength as well as from metallurgical reasons under a certain amount

Wandstärke nicht gegangen werden kann. Weiterhin hat aber das bekannte Säulengestell den Nachteil, daß bei Versand der Maschine außer dem großen Gewicht der Raumbedarf infolge der an die Grundplatte fest angegossenen Säule ein ziemlich großer ist.Wall thickness can not be gone. However, the well-known column frame continues to exist the disadvantage that, in addition to the great weight, the space required when shipping the machine due to the column firmly cast on the base plate, it is quite a large one.

Die Erfindung betrifft nun ein Säulengestell, welches nicht nur obige Nachteile vermeidet, sondern gleichzeitig ein leichtes Auseinandernehmen des Stativs gewährleistet.The invention now relates to a column frame, which not only avoids the above disadvantages, but at the same time makes it easy to dismantle of the tripod guaranteed.

Hierzu kennzeichnet sich der Erfindungsgegenstand dadurch, daß die Säule aus einem Blechformstück besteht, welches zwischen dem Fuß- und dem Kopfstück durch eine Zugschraube gehalten wird.For this purpose, the subject matter of the invention is characterized in that the column consists of a Sheet metal fitting is made, which is between the foot and the head piece by a tension screw is held.

In der Zeichnung ist der Längsschnitt einer beispielsweisen Ausführungsform wiedergegeben In the drawing, the longitudinal section of an exemplary embodiment is shown

Das neue "Säulengestell besteht aus dem ao Säulenfuß 1, dem Säulenmittelstück 2, und dem Säulenkopi 3. Säulenfuß 1 sowie Säulenkopf 3 sind zweckmäßigerweise aus Guß hergestellt, während das verhältnismäßig einfache Säulenmittelstück 2 aus dünnwandigem Bleclimaterial bestehtThe new "pillar frame consists of the ao pillar base 1, the pillar center piece 2, and the column head 3. Column foot 1 and column head 3 are expediently made of cast made, while the relatively simple column center piece 2 made of thin-walled Sheet metal material is made

Der Zusammenhalt der drei vorgenannten Teile erfolgt durch eine einzige Zugschraube 4, welche im Säulenfuß r und im Säulenkopf 3 so angeordnet ist, daß mit Hilfe von Muttern 5, 6 sich der Säulenkopf 3 fest gegen den Säulenfuß 1 und das Säulenmittelstück 2 zusammenziehen läßt. Nach Lösen der Mutter s oder 6 ist das gesamte Gestell in der denkbar einfachsten Weise auseinandernehmbar. The three parts mentioned above are held together by a single tension screw 4, which is arranged in the column base r and in the column head 3 that with the help of nuts 5, 6, the column head 3 is firmly against the column base 1 and the column center section 2 pulls together. After loosening the nut s or 6, the entire frame is in the Can be dismantled in the simplest possible way.

Der innere Hohlraum 7 des Säulenstativs kann in bekannter Weise zur Unterbringung von elektrischen Zubehörteilen, wie Ausschalter 8 für die Lampe des Projektionsapparates, Regulieranlasser 9 für den Antriebsmotor des kinematographischen Vorführungsapparates, elektrischen Zubehörteilen für die Stillstandseinrichtung, etwa nötigen elektrischen Meßinstrumenten eines Transformators 10, sowie· des Antreibmotors ausgenutzt werden.The inner cavity 7 of the column stand can be accommodated in a known manner of electrical accessories, such as switch 8 for the lamp of the projector, Regulating starter 9 for the drive motor of the cinematographic demonstration apparatus, electrical accessories for the standstill device, any necessary electrical measuring instruments a transformer 10, as well as · the drive motor can be used.
