Sprechmaschine mit mehreren Phonogrammträgern.Speaking machine with several phonogram carriers.

Patentiert im Deutschen Reiche vom 5. Juni 1913 ab.Patented in the German Empire on June 5, 1913.

. Die Erfindung bezieht sich auf Sprechmaschinen mit mehreren Phonogrammträgern und mehreren zwangläufig miteinander verbundenen und in derselben Richtung schwingenden Schallarmen und besteht darin, daß zur Führung der Schallarme zwangläufig miteinander verbundene Kronräder mit einer Reihe von Lagern (Aussparungen) dienen, in die die Schallarme gelegt werden können. Diese Einrichtung ermöglicht die Abspielung beliebig langer Stücke schon mit zwei Schallarmen und mit zwei Phonogrammen in der Weise, daß man, während der eine Schallarm spielt, den anderen aus der Aussparung seines Kronrades aushebt, den Phonogrammträger wechselt, und dann den Schallarm in die folgende Aussparung des Kronrades einlegt, wodurch er von selbst wieder auf den Anfang des neuen Phonogramms eingestellt ist.. The invention relates to speaking machines with several phonogram carriers and several inevitably interconnected and oscillating in the same direction Low noise and consists in the fact that to guide the sound arms inevitably with each other connected crown wheels with a number of bearings (recesses) are used in which the Noise arms can be placed. This facility enables playback as desired long pieces already with two sound arms and with two phonograms in the way, that while one is playing the sound arm, the other is out of the recess of his crown wheel lifts out, changes the phonogram carrier, and then the sound arm in the following one Recess of the crown wheel inserts, making it back to the beginning of the new one by itself Phonogram is set.

Auf einer Spielplatte wandert der Schallstift den Spiralen entsprechend, von einem Punkte α nach einem Punkte b zwischen dem möglichen Anfangspunkt und Endpunkt der Spirale. Während dieser Zeitspanne bewegt sich die Achse, welche den Schalltrichter und die Schalldose trägt, um einen Winkel α. Wenn man zwei Plattenteller, die die Spielplatten tragen, derart kuppelt, daß sie mit einer gleichmäßigen Geschwindigkeit sich drehen, kann man das Wandern der einen Schalldose dazu ausnutzen, um nach einem Winkel a' die Schalldose der zweiten Platte in eine solche Lage zu bringen, daß ihr Schallstift gerade auf den Punkt a', der den Anfang der Aufzeichnung der zweiten Platte darstellt, fällt und auf diese Weise die Aufzeichnung der ersten Platte gewissermaßen fortgesetzt wird. Durch denselben Antrieb wird der zweite Schallarm den ersten rückwärts um einen Winkel af = λ zurückführen, und zwar zu einem Punkte, wo die erste Nadel auf einen Punkt a" fallen kann, sobald die zweite Platte bei V angelangt ist. Der Punkt a" tritt an Stelle des Punktes a. Auf "diese Weise wird gewissermaßen die Aufzeichnung der ersten Platte durch eine dritte Platte ersetzt und die der zweiten Platte fortgesetzt. Fährt man auf diese Weise weiter fort, so kann man abwechselnd die Platten ändern, wobei jedesmal der wirksame Schallstift den andern derart mitnehmen wird, daß er ihn an den Anfangspunkt der neuen Platte heranführt. Es ist begreiflich, daß diese Wirkung ins Unendliche fortgesetzt werden kann. Es sind nun gewisse Einzelheiten zu beobachten, um praktisch diese Grundidee verwerten zu können.On a playing plate, the sound pen moves according to the spirals, from a point α to a point b between the possible starting point and the end point of the spiral. During this period of time, the axis that carries the horn and the sound box moves through an angle α. If two turntables, which carry the playing discs, are coupled in such a way that they rotate at a constant speed, the wandering of one sound box can be used to bring the sound box of the second plate into such a position after an angle a ' that its sound pen just falls on point a ', which represents the beginning of the recording of the second disk, and in this way the recording of the first disk is, as it were, continued. By the same drive, the second sonic arm will guide the first backwards by an angle af = λ to a point where the first needle can fall onto a point a " as soon as the second plate has reached V. The point a" occurs instead of point a. In this way, as it were, the recording of the first disk is replaced by a third disk and that of the second disk is continued. that it leads him to the starting point of the new record. It is understandable that this effect can be continued indefinitely. Certain details must now be observed in order to be able to utilize this basic idea in practice.

Es ist bereits erwähnt worden, daß die Plattenteller 1,1' Spielplatten tragen, die in demselben Sinne mit einer vollständig gleichen Geschwindigkeit sich bewegen. Die PlattenIt has already been mentioned that the turntables carry 1.1 'playing discs which are in move in the same sense at an entirely equal speed. The plates

2, 2' werden unter Zuhilfenahme von Stiften2, 2 'are made with the help of pens

3, 3' mitgenommen, welche sie innerhalb von3, 3 'taken, which they within

Claims

Grooves 4, 4 'reach through. The position of the end of the grooves 4, 4 'is chosen such that when the left sound pen is at b , the right one is just at a' and vice versa.

On the support knee 5 of the horn are two completely identical crown-like wheels 6, 6 'provided with notches 7, 7', which are coupled to one another by a gear wheel 8 are so that they can rotate evenly and influence each other.

In the drawings, ten notches are provided on each wheel. You are to it intended to accommodate the sound arms 9, 9 '.

When the sonic arm 9 has completed its work path (FIG. 1), it has previously been taken along in the direction of arrow y. Here, the wheel 6 has taken the wheel 6 'in the direction of the arrow y' . This movement was followed by the sonic arm 0 /. While it was initially in position c ', it has gradually been brought into position a' , the angle a! = α is. During this adjustment, it is carried by a thumb 10 'which slides on a guide 11'. As a result, his sonic pen was lowered directly to point a ' at the moment when the first sonic pen had reached b . At this moment (Fig. 1) the first game board is played and the second comes into effect without interruption.

Now you lift the arm 9 and insert it into the notch 7, which is located located on line c. The second arm 9 'influences the movement of the first in completely the same way.

While the second board is playing, the first is lifted off. For this purpose, a pawl 12 (FIG. 4) frees a lever 13 so that the axis 14 of the turntable can be lifted. Instead of the plate 2, a plate is inserted, the pawl 12 is returned to its original position and the pin 3 is allowed to fall into the notch 4 with the aid of a brake 15. You let the plate run, and. just at the moment when the second sound pen is in V (end of the second plate), the first tip falls smoothly into α (beginning of the third plate) etc.

If you let this phonograph run synchronously with a cinematograph, you can make a talking film of unlimited length. If, for example, images are projected by the cinematograph during a rotation of the first plate η , one becomes when the surface of the plate

in η sectors - and the point a with

coincides with the appearance of the first picture, an absolutely certain coincidence of the Appearance of the η images with the η points of the first spiral. Because the speed of the plate is constant, the η following images are from the second spiral accompanied etc. For each sector, approximately the first two thirds of the appearing and the last third coincide with the darkening caused by the Sluggishness of the eye is not perceived. It will therefore be possible to click each picture of the plate and to be repeated on all subsequent plates. This is accompanied by the projects an image with great accuracy and throughout its duration, like no matter how long it is achieved. If a picture is spoiled, the film can be cut up, and for example omit η images. A groove will be provided by adding the sonic pen is passed around a spiral, causing the speaking apparatus to pull the tape will catch up again. Individual safety measures can still be taken.

The first two or three turns of the sound curve can be known, for example Kind of wider to ensure better guidance for the sonic pen. The first and last turns can also be empty, and one could use an automatic device provide by which the sonic pen is automatically raised at the end of each plate would be.
