Description

Field of use:

The invention relates to an overhead line operation over the swing bridge of a mine put electric turntable, which is a general continuous game operation with accommodation for all on the model railroad layout Locomotives enabled.

Purpose:

The purpose of the invention is that an upper Line operation over the swing bridge of a swing disc is created so that a connection between the single or multiple ring locomotive shed on the one hand and the transition track or tracks on the other hand is manufactured to the turntable in the upper to incorporate line operation.

State of the art (with criticism) and sources:

According to previous knowledge of the latest catalogs of the companies
Gebr. Märklin & Cie GmbH, PO Box 860/880, 7320 Göppingen, and
Gebr. Fleischmann, P.O.Box 910 148, 8500 Nuremberg 91, is the basis, so far only one line operation is possible for turntables; the two best-known as well as other companies operating in this field lack instructions for running the overhead lines.

Achievable advantages:

The use of electric locomotives on model railroad layouts with turntable could by the additional game operation on catenary basis be increased, while the applicability of an electric turntable is expanded, which is serious in both cases Could result in increased sales.

Object of the invention:

The invention has the task that

• a) no longer just steam and diesel locomotives but also Electric locomotives transported over the turntable of the turntable and can be accommodated in the roundhouse;
• b) through the newly created system a corresponding one Contact is made with only one im Turntable area responsible transformer Upper and lower line with the same power supply.

 Solution of the task:

The object is achieved according to the invention by combining different makes on the basis of the following description ( Fig. 1 / before + Fig. 2 / after):

In order to compensate for the height difference between the electric turntable in pit construction and the M tracks on the model railroad layout, it is raised below by a wooden ring of appropriate strength and width.

In the case of 2 lattice masts (metal), a change is made in that a correspondingly long and strong screw with screw nut is used at a certain height, which is delimited at a given distance by another screw nut and at the end by a cap nut ( Fig. 3); these two repurposed masts are used diagonally on the swivel bridge of the electric turntable in pits in a precisely calculated distance from the center to the outer edge by means of holes drilled to the side from the edge ( Fig. 1 + 2 / Fig. 2 + 5); below the swing bridge, the screw threads of the masts are fastened and shortened with screw nuts.

In the case of overhead contact wires, Ver changes made by soldering as

• a) the ends are formed at right angles so that two straight lines with a curved edge are formed ( FIG. 4),
• b) 1 soldered eyelet is formed on both sides ( Fig. 4) and
• c) a specially formed for the gate wing of the ring locomotive overhead contact wire is designed as a single wire ( Fig. 4) and
• d) 3 further soldered-in eyelets are formed at the appropriate distance from the front end ( Fig. 4).

An insulated cable (wire) is soldered to the right or left of the spring plate ( Fig. 5), which is located in the middle under the two middle rails of the swing bridge ( Fig. 3 / Fig. 5) The cavity underneath the swivel bridge is led out and with another hole next to the lattice mast ( Fig. 4 / Fig. 2 + 5) inside the same up again and additionally soldered to the screw above the mast at a certain height ( Fig. 5 / Fig. 3).

In the turntable area in front of the electric turntable

• a) next to the transition track or tracks, either on the right or left, 1 converted lattice mast with a longer screw attached at a certain height is mounted using a mast foot ( Fig. 9 / Fig. 3), the mast or the masts are provided with cables ( Fig. 6 / Fig. 1 + 3);
• b) outside the ring locomotive shed, converted lattice masts at the same height are also installed by means of a mast foot next to the individual gate entrances, all masts being provided with cables ( Fig. 6 / Fig. 1 + 3;
• c) inside the ring locomotive shed, converted lattice masts are mounted at a certain height (without mast foot) behind the gate entrances and diagonally in front of the rear wall of the ring locomotive shed without cables ( Fig. 7 / Fig. 2 + 3).

Achievable advantages:

These changes provide the opportunity

• 1. during play operation, clamp the continuous overhead contact wire between the screw nut and cap nut above the converted lattice mast and thereby keep it stable ( Fig. 8 / Fig. 3),
• 2. to take over the further power supply as required, which is now also about the overhead contact wire be wrapped and advantageously by a direction of signal points can take place and
• 3. by tapping the middle rail under the turn bridge as well as the middle rail under each Track in the roundhouse a power supply to the upper to produce line, which also for the siding or the tracks on the other side behind the shoot disc edge applies.

Transitional design (end of the turntable area):

The right and left of the transition track or the -track around in front of the turntable edge worked lattice mast (with cable and mast base) takes a breaker as overhead contact wire (Cam piece) at a certain distance from the front End on, causing a separation of the routing for the overhead line operation results to at the same time for the associated signaling device to take effect.

Since the turntable area ends here, are from now on to operate 2 transformers again to and subway operation and the signaling device to put into operation.

The continuation of the routing are common Lattice masts with side brackets (outrigger) for upper cable contact wires.

Claims (1)
