Description
Sprechmaschine. Zusatz zum Patent qoxr78. Durch das Patent .40117 8 ist an einer Sprechmaschine mit federnd aufgehängtem Motor und Schnurantrieb 'das Merkmal geschützt, daß die Schnur über Zwischenrollen geführt ist und gleichzeitig eines der Aufhängeorgane des Motors bildet. Bei der Ausführungsform nach dem Hauptpateat laufen die Zwischenrollen in Lagern, die starr an der Decke des Sprechmaschinengehäuses befestigt sind. Es ist zwar in. der Beschreibung des Hauptpatents bereits darauf hingewiesen worden, daß die Leitrollen auch federnd gelagert werden können. Hierbei ergibt sich aber die Schwierigkeit, daB wegen der in der Schnur auftretenden Zugkräfte die Anhängung der Leitrollen an Federn allein nicht angeht. Werden aber beispielsweise -an der Gehäusedecke angebrachte Führungen benützt, in denen die Lager der Rollen sich auf und nieder bewegen können, so bilden die starren Führungen wie-'der ein. geeignetes Mittel zur Fortleitung der Geräusche.Talking machine. Addition to the qoxr78 patent. The patent .40117 8 protects the feature on a speaking machine with a spring-mounted motor and cord drive that the cord is guided over intermediate rollers and at the same time forms one of the suspension elements of the motor. In the embodiment according to the main patent, the intermediate rollers run in bearings that are rigidly attached to the ceiling of the speaking machine housing. It has already been pointed out in the description of the main patent that the guide rollers can also be resiliently mounted. Here, however, the difficulty arises that because of the tensile forces occurring in the cord, the attachment of the guide rollers to springs alone is not an issue. However, if, for example , guides attached to the housing cover are used in which the bearings of the rollers can move up and down, the rigid guides form a new one. suitable means for the propagation of the noises.
Nach der Erfindung-ist nun die angegebene Schwierigkeit dadurch überwunden, daB die Lager der Leitrollen einerseits an der Gehäusedecke mittels Federn aufgehängt, an, dererseits durch Arme gegen den Motorrahmen oder den Motor abgestützt sind.According to the invention, the stated difficulty has now been overcome by that the Bearings of the guide rollers on the one hand on the housing cover by means of Springs suspended on, in turn, by arms against the engine frame or the engine are supported.
Auf der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform veranschaulicht, und zwar zeigen Abb. i denselben von der Seite und Abb. z von oben gesehen.The subject of the invention is shown in an exemplary manner in the drawing Embodiment illustrated, namely Fig. I show the same from the side and Fig.z seen from above.
Die Lager o der Rollen, i sind hier am Ende einer Gabel p angeordnet, deren beide Arme sich mit Hilfe von Gelenken r auf den Motorrahmen b stützen. Die in der Schnur wirksam werdenden Zugkräfte werden also von der Gabel aufgenommen. Das freie Ende der Gabel ist an der Gehäusedecke h mit Hilfe der Feder s aufgehängt.The bearings o of the rollers, i are arranged here at the end of a fork p, the two arms of which are supported on the motor frame b with the aid of joints r. the Tensile forces that take effect in the cord are thus absorbed by the fork. The free end of the fork is suspended from the housing cover h with the aid of the spring s.
Infolge dieser Anordnung ist eine starre Verbindung zwischen dem Gehäuse und irgendeinem Getriebeteil nicht mehr vorhanden, und die übertragung von Motorgeräuschen ist daher, soweit es nur möglich ist, beseitigt. Zwischen der Feder s und der Schnur f voll- zieht sich dauernd ein Ausfleich der Spannungen, wobei die Gabel p um ihre Drehzapfen r geringe Schwingungen ausführt.As a result of this arrangement, there is no longer a rigid connection between the housing and any transmission part, and the transmission of engine noise is therefore eliminated as far as possible. S between the spring and the line f fully runs permanently on Ausfleich the voltages, the p fork about its pivot r vibrate executes.
