Vorliegende Erfindung bezieht sich auf eine Doppellampe mit Umschaltvorrichtung. Die Lampe enthält zwei völlig von einander getrennte Regelungswerke.The present invention relates to a double lamp with a switching device. the The lamp contains two completely separate sets of rules.

Auf die Laufwerke aa_x (Fig. 1) wirken die beiden einspuligen Elektromagnete b b_l , von denen der letztere in der Zeichnung theilweise verdeckt erscheint, mittels der zugehörigen Anker und der Zugstange c C₁ ein. Es könnten jedoch auch beide Laufwerke von einem gemeinschaftlichen Magneten beeinflufst werden. Zu jedem Laufwerk gehört ein. Paar beweglicher Kohlenhalter. Die beiden Laufwerke stehen in Verbindung mit der Umschaltvorrichtung, von der sie wechselseitig beeinflufst werden. Diese Vorrichtung besteht, wie aus den Fig. 2a, 2b und 2c ersichtlich ist, aus dem Umschalthebel d, der zwei Anschlagzungen e e_Y trägt, die je nach der Stellung des Hebels d das eine oder das andere Laufwerk festhalten bezw. freigeben, sowie dem umschlagbaren Hebel f, der unter dem Einflufs der beiden Zugstangen g g_x und der Blattfeder h steht.The two single-coil electromagnets bb _l , of which the latter appears partially covered in the drawing, act on the drives aa _x (Fig. 1) by means of the associated armature and the pull rod c C ₁ . However, both drives could also be influenced by a common magnet. Each drive has a. Pair of movable charcoal holders. The two drives are connected to the switching device, by which they are mutually influenced. This device consists, as shown in FIGS. 2a, 2b and 2c it is apparent d of the switching lever, the two stop tongues ee _Y carries BEZW hold the d according to the position of the lever one or the other drive. release, as well as the reversible lever f, which is under the influence of the two tie rods gg _x and the leaf spring h .

Der Vorgang beim Umschalten ist folgender: Sobald das eine Kohlenpaar nahezu abgebrannt ist,, legt sich der zugehörige obere Kohlenhalter auf einen Bund der entsprechenden Zugstange und nimmt dadurch den umschlagbaren Hebel f mit, wobei der Excenterdaumen η die auf der Feder h sitzende Rolle i so weit anhebt, bis dieselbe über seinen Todtpunkt'hinweg ist, in welchem Zeitpunkt der durch die Spannung der Feder h erfolgende Rückgang der Rolle den Daumen bezw. den Hebel f in die Endlage drückt, wobei die beiden Zugstangen dieser Bewegung folgen, und der Hebel d plötzlich von der einen, äufsersten Lage in die andere gedrückt wird,, dabei das eine Laufwerk freigebend, das andere festhaltend.The process when switching is as follows: As soon as the one pair of coals has almost burned down, the associated upper coal holder lies on a collar of the corresponding pull rod and thereby takes the reversible lever f with it, with the eccentric thumb η the roller i sitting on the spring h raises far, until the same is over his Todtpunkt'hinweg, at which point in time the decrease of the role taking place by the tension of the spring h the thumb resp. pushes the lever f into the end position, the two tie rods following this movement, and the lever d is suddenly pushed from the one, outermost position to the other, releasing one drive while holding the other.

An Hand von Fig. 1 kann man sich diesen Vorgang leicht veranschaulichen. Das Kohlenpaar I ist nahezu abgebrannt, der obere Kohlenhalter t hat sich auf den Bund k der Zug^ stange g gelegt und dieselbe schon so weit mitgenommen, dafs die Rolle i bereits den Todtpunkt des Excenterdaumens erreicht^ hat; es fehlt also nur noch eine geringe Bewegung des oberen Kohlenhalters t und der Hebel f wird umschlagen, den Hebel d hierbei mitnehmen und somit, das Laufwerk α_λ frei machen. Dieses setzt sich durch das Gewicht des oberen Kohlenhälters in Bewegung, bis das Kohlenpaar II auf einander stöfst und der neue Lichtbogen gebildet ist. Gleichzeitig .erlischt der bisherige Bogen und das Kohlenpaar I wird durch die Anschlagzunge e festgehalten, so dafs die Kohlen nicht wieder in Berührung kommen können. Ganz derselbe Vorgang wird sich abspielen, wenn das Paar II abgebrannt und das Paar I inzwischen erneuert worden ist.This process can easily be illustrated with reference to FIG. 1. The coal pair I has almost burned down, the upper coal holder t has placed itself on the collar k of the pull rod g and has already taken it with it so far that the roller i has already reached the dead point of the eccentric thumb; So there is only a slight movement of the upper carbon holder t missing and the lever f will turn over, taking the lever d with it and thus freeing the drive α _λ. This is set in motion by the weight of the upper coal holder until the pair of coals II collide and the new arc is formed. At the same time, the previous bow is extinguished and the pair of coals I is held in place by the stop tongue e so that the coals cannot come into contact again. The same process will take place if pair II burned down and pair I has been renewed in the meantime.

Der umschlagbare Hebel f ist aber kein unbedingt nothwendiger Theil der neuen Anordnung. Es kommt die Umschaltung auch ohne diesen Hebel zu Stande, wenn die beiden Zugstangen unmittelbar auf den Schalthebel d einwirken. Es ist dann aber nöthig, dafs die beiden Anschlagzungen so eingestellt werden, dafs die eine ihr Laufwerk losläfst, wenn die andere im Begriff ist, das zugehörige Laufwerk festzuhalten. Da diese genaue Einstellung in der Praxis Schwierigkeiten macht, so ist es er-The reversible lever f , however, is not an absolutely necessary part of the new arrangement. Switching takes place even without this lever when the two tie rods act directly on the shift lever d . It is then necessary, however, that the two stop tongues are set in such a way that one releases its drive when the other is about to hold the associated drive. Since this exact setting causes difficulties in practice, it is

Claims

It is necessary to quickly bring the shift lever into its end positions, for which purpose the reversible lever is used. As much is known, other double-coal lamps have the disadvantage that both coals are burned out before the coals are changed and that both coals must always be renewed at the same time. The present innovation, on the other hand, allows each pair of coals to be renewed individually and thereby has the advantage that each pair of coals burns down to the last stump. Arc lamps with this innovation can therefore be operated in different ways; Either each pair of coal is renewed for itself or both coal pairs are renewed at the same time, depending on whether one wants to save more coal or more work. Instead of generally saving on work, one can also intend to generate more light by choosing the coal diameter smaller and still achieving a normal burning time by doubling the coals. In Figs. 3, 4 and 5 some other embodiments of this device are shown. In Fig. 3, instead of the leaf spring h, a helical spring m with a slightly different lever device is arranged. In Fig. 4, instead of the spring, a turning weight 0 is arranged and in Fig. 5 the weight 0 does not act on a lever provided with two special stop tongues, but with the aid of a push rod u on the two common ones used in the control arranged tongues, as can be seen from the schematic drawing. In place of the weight ο springs can be used here, in place of the drives also other inhibiting mechanisms, even friction couplings, and instead of the tie rod collars k Ar1 protruding parts of the chain roller or the chain can be used. The shift lever can also be moved electrically, as shown in FIGS. 6, 7, 8 and 9. In Fig. 6, the upper carbon holders are provided with contacts ^ p1, which lie on the power circuit pieces q qx attached to the rods of the lamp, whereby one of the coils / T1 is switched on each time. In the position of the coal holder assumed in FIG. 6, the coil r is switched on and the core s has been drawn in, whereby the lever d has been switched over and the second drive has been released. If the pair I is replaced before the pair of coals II has completely burned down, the gear lever d could play freely and thus come into a wrong position, for example due to vibrations. To prevent this, the lever f is provided with a turning weight 0, which holds it in every end position. In Fig. 7, instead of this weight, the spring m is arranged for the same purpose. In Fig. 8 the armature iron of the switchover magnet strikes the iron of the core directly, so that the remanent magnetism secures the lever in its end position. FIG. 9 again shows, like FIG. 5, the reversible lever f in connection with a pull rod u, which moves the two usual stop tongues for switching. In a similar way, various embodiments of the same basic idea can be found; B. the arranged in Fig. 5 and 9 levers% ^ 1 are combined into one lever. The lamps with this innovation can be designed as secondary as well as differential lamps and can be operated with any type of current. '■ Pateντ claims:
