Der Stromabnehmer nach vorliegender Erfindung setzt sich aus drei Haupttheilen zusammen, einem vom Führerstande aus einstellbaren Schleifschuh, einem drehbaren sowie axial beweglichen Ausleger und einer mit der Lokomotive fest verbundenen Rollenführung für den Ausleger.The pantograph according to the present invention consists of three main parts, a sanding pad adjustable from the driver's cab, a rotatable and axially movable boom and one with the Locomotive firmly connected roller guide for the boom.

Bei Anwendung von Mehrphasenströmen erhält jede Phase der Stromzuführung ihren eigenen Stromabnehmer.When using multiphase currents, each phase of the power supply receives its own own pantograph.

Der Stromabnehmer läfst drei Bewegungen des Schleifschuhes H zu: Erstens kann der Schleifschuh um den Zapfen Z bis zu etwa 120⁰ gedreht werden. Zweitens kann der in der Betriebsstellung lothrechte Arm A des Auslegers L L¹ aus dem Schutzgehäuse G durch eine Drehung herausgehoben werden. Drittens kann sich, wie dies durch die Anwendung der geschützt angeordneten Niederleitung bedingt ist, der Ausleger L Z,¹ in seiner Längsrichtung bis zu etwa 1 m bewegen.The current collector of the grinding shoe läfst H to three motions: first, the sanding shoe about the pin Z can be rotated up to about 120 ^0th Second, the arm A of the boom LL ¹ , which is perpendicular in the operating position, can be lifted out of the protective housing G by turning. Thirdly, as is due to the use of the protected lower line, the boom L Z, ^{1 can} move in its longitudinal direction up to about 1 m.

Der Schleifschuh H (Fig. 4 und 5), welcher von einer gewellten Kupferplatte mit einer Isolationslage gebildet wird, besitzt einen cylindrischen Ansatz mit Bohrung h; letztere ist auf dem Zapfen Z aufgeschliffen, so dafs der Schleifschuh den Strom von der Leitung auf den Zapfen Z sicher überträgt, jedoch sich auch leicht um denselben drehen kann. Nachdem der mit der Bohrung h versehene cylindrische Ansatz auf den Zapfen Z heraufgeschoben ist, wird niit Hülfe des Zwischengliedes m der Isolationskörper / durch Schrauben si an dem Ansätze befestigt, so dafs alsdann diese drei Theile zu einem festen Ganzen verbunden sind, welches sich um den Zapfen Z drehen kann. Die Drehung des Schleifschuhes H wird durch seitliche Anschläge für den Körper m begrenzt . (Fig. 6).The sanding shoe H (FIGS. 4 and 5), which is formed by a corrugated copper plate with an insulation layer, has a cylindrical attachment with a bore h; the latter is ground on the pin Z , so that the sanding shoe reliably transfers the current from the line to the pin Z , but can also easily rotate about the same. After the cylindrical attachment provided with the bore h has been pushed up onto the pin Z , the insulating body is fastened to the attachment with the aid of the intermediate member m / by screws si, so that these three parts are then connected to form a solid whole which surrounds the Pin Z can rotate. The rotation of the sanding shoe H is limited by lateral stops for the body m. (Fig. 6).

In dem Isolationskörper I ist die biegsame Welle w befestigt; dieselbe bewegt sich in einem Rohre, welches innerhalb des Auslegers bis unter die Lokomotive geführt wird, tritt alsdann aus demselben frei heraus und kann von hier mit einem Anschlufsbogen bis zum Führerstande bezw. jedem anderen Punkte der elektrischen Lokomotive verlängert und durch die Kurbel K gedreht werden (Fig. 1 und 2). Der Lokomotivführer ist demnach im Stande, den Schleifschuh H aufrecht einzustellen, wie in Fig. 4 punktirt gezeichnet, oder zum Gebrauch auf die Stromleitung herab zu lassen.The flexible shaft w is fastened in the insulating body I; the same moves in a pipe, which is guided within the boom to under the locomotive, then emerges from the same freely and can bezw from here with a connecting bend to the driver's cab. every other point of the electric locomotive can be extended and rotated by the crank K (Fig. 1 and 2). The locomotive driver is accordingly able to set the sanding shoe H upright, as shown in dotted lines in FIG. 4, or to lower it onto the power line for use.

Der Stromabnehmerarm A und der Ausleger L sind durch die Muffe M (Fig. 4 und 5)The pantograph arm A and the bracket L are through the sleeve M (Fig. 4 and 5)

Claims

tied together; in both parts both the copper line e, which ends in the pin Z, and the flexible shaft n> are routed insulated from each other and from the outer protective and supporting tube. The outer sleeve of the customer A consists of steel of oval cross-section (Fig. 8), so that it can slide unhindered in the slot Sch of the slot housing G, also easily dividing any obstacles (snow and ice). The outer sleeve of the arm L L1 consists of a double tube. The inner tube L1, which encloses the power supply line e and the flexible shaft w insulated from one another, is rotatable in the outer tube L, guided through the sliding rings g gl (Fig. 9), so that the guide is guided by means of the rod F and of the lever B (Fig. ι and 9), which is connected to L1, rotate the tube L1 and also the arm A and the latter can move in and out of the protective housing G. By virtue of the roller guide of the boom L (FIGS. 3 and 9), the arm A sliding in the slot Sch can follow unimpeded the inequalities caused by the system in the distance between the housing slot Sch and the track of the locomotive. The roller guide consists of two rings R and R1, in each of which three rollers adjustable with screw connections are now attached; In these six rollers, which are turned out according to the cylinder surface of the pipe L, the boom L moves in the axial direction. The rings R and jR1 are screwed onto a plate P which rests on a support T fastened between two axial bearings. The flexible shaft w will be able to easily follow the lateral movements of the boom without further ado. The power supply e is given a few turns in order to also be able to follow the movements of the boom without mechanical tension (Fig. 1). By means of the rod F, the current collector can both be rotated and moved in its longitudinal direction. The driver is therefore able from his position to switch the sanding shoe on and off, as well as to rotate the boom at any distance between the track and the protective housing and to adjust it in the longitudinal direction, which means that arm A is engaged and disengaged is made possible. The boom can also adjust automatically in the axial direction. Godfather τ-An Proverbs:

1. A current collector for electric railways with a working line in a protective side housing, characterized in that, while the grinding shoe (H) can be adjusted from the driver's cab, the arm (A) guided in the housing slot (Sch ) around a horizontal arm (LL ¹ ) rotatable as an axis and the boom (LL ¹ ) itself is axially displaceable for the purpose of automatically adapting the pantograph to the inequalities in the distance between the housing slot and the locomotive.

2. An embodiment of the current collector according to claim 1, in which the rotation of the grinding shoe (H) takes place by means of a flexible shaft (w) .

3. An embodiment of the current collector according to claim 1, in which the rotation of the boom (LL ¹ ) in the bearing rings (gg ¹ ) and the axial guidance of the same by a number of rollers (uu) takes place.
