It provides a system wherein a main train may be interlocked with a local train to effect the transfer of passenger and/or goods, while the main train is travelling at a high speed. I
2. Description of the Prior Art It is known in the prior art that goods may be transferred between moving trains which are interlocked. For example note Barry US. Pat. No. 3,483,829. It is also known that passengers may be transferred between moving trains; note Cook US. Pat. No. 881,377.
Means for locking railroad cars .together are also known in the prior art. For example note Kennedy US. Pat. No. 3,489,101. The Baldwin US. Pat. No. 2,467,354 discloses the use of conveyor equipment to transfer logs between a loading station and a pulp mill, wherein a freight car is utilized at the loading station.
SUMMARY OF THE DISCLOSURE The prior art does not disclose however the utilization of curtain roofs to provide a closed passageway for the transfer of passengers between'moving trains, and which further insures the safety of passengers by foreclosing the possibility that passengers might remain on the passenger bridge between trains as the trains are being decoupled. 1
The prior art also does not disclose the use of wind deflectors operable while the trains are interlocked to prevent the wind factor from adversely influencing the transfer of passengers and/or goods.
The railway system according to the invention has particular utility in an environment where a train running on a main track is to be coupled or interlocked with a train running on a local line, while the two trains are in motion. This enables the main train to be run at high speeds, with goods being loadedthereon or dis charged therefrom to the local train without stopping the main train. The local lines may be spaced at desired locations along the main line. The spacing between main and local lines is so close that when trains on both lines are aligned, means on both trains interlock them for synchronized motion. Conveyer means on both trains then cause goods to be transferred along horizontal transverse paths from either the local to the main train or vice versa. After the transfer is completed, the trains are decoupled; the main trains continue on route; and the local trains are either unloaded or reloaded with goods. Thus the main trains run always at high speed with goods being loaded thereon or discharged therefrom without the delays of stops and starts for loading or unloading.
In the case of passenger trains, the use of conveyer is unnecessary. In such instances, when the trains are engaged, floors are extended laterally from the side of each train to form a bridge for passengers to cross from one trainto another. The facing sides of each train are provided with a number of folding doors which open after the bridge has been formed by the extendible floors. The bridges also are provided with curtain roofs which extend from each train and prior to disengagement of the trains extend downward to the outer edges of the extendible floors in order to assure that no passengers are left on the bridge prior to retraction of the extendable floors.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. I is a perspective'view showing a, main line interlocked with a local line to effect the transfer of goods therebetween;
FIGS. 6 and 7 show an interlocking means for the trains.
DETAILED DESCRIPTION OF THE DISCLOSURE FIG. 1 shows the railway system according to the invention wherein parallel tracks 10 and 11 respectively have trains 12 and 13 travellin'g'thereonFor purposes of explaining the invention, track l0is designated the main line, and track 11 the local line. The main line for exemplary purposes may be used for long distance runs such as coast-to-coast travel, and the local line identifies a particular location along the long distance run. A plurality of local lines are located at spaced locations along the main line. The local tracks may comprise loops 14 as shown in FIG. 2, or may be major lines which intersect each other, or trains on rails in closed loops may shuttle between two railways.
With reference to FIG. 1, let it be assumed that train 12 is travelling at a high speed along track 10 and is to be coupled with train 13 which is located on track 11. As the main train 12 travels into adjoining relationship with local train 13, the trains are automatically interv locked as shown in FIGS. 6 and 7. Train 12 includes a mechanism 20 which is ejected when trains l2 and 13 are properly aligned. When mechanism 20 is ejected, wheel 21 is propelled outwardly from 12 towards train 13, as shown in FIG. 3. With reference to FIG. 6, horizontal wheel 21 isprovided with an electrically conductive layer 22 which fits into a track on train 13. More specifically, horizontal wheel 21 is connected to train 12 with cast steel holders 23 and 24 against plate 26 with spring plates25 against plate 27 against the train bulkhead or chassis, fastened with bolts. When layer 22 on horizontal wheel 21 comes in contact with train 13, it pushes in electrically conductive rod 28 contained in bearing 29, forcing spring 30 to close an electrical circuit. At the same time, a signal is transmitted to the operator of train 12, conductive block 28 being in contact with the conductive layer 22 on the horizontal FIG. 4 shows the manner in which interconnected trains 12 and 13 may be used to transfer passengers therebetween. When the trains are in proper alignment and are interlocked extendable floors 40 and 41 are automatically extended from trains l2 and 13 respectively to form a passenger bridge therebetween. Concurrently a curtain roll 42 which is mounted on the roof of train 12 is caused to unroll and is supported by side 43 extending from the floor 41. The other extremity of train 12 and more specifically each car thereof has a complementary wall 43. The roof curtain provides a protective system to protect passengers being transferred from the environment and provide a safety feature as explained hereafter. Train 13 is provided with a similar curtain roof 45 and provides a ceiling between trains 12 and 13 when curtain roofs 42 and 45 are extended. The curtain roofs 42 and 45 are connected by conventional means such as hooks (not shown) to walls 43 and 46 respectively and are extendable therewith. When the transfer of passengers is completed between trains l2 and 13, curtain roofs 42 and 45 respectively are automatically moved to extendable floors 40 and 41. The curtain roofs are locked by conventional means such as hooks (not shown) to their respective extendable floors, and as the floors are retracted back into their respective trains prevent the possibility that passengers might be left on the passenger bridge as the floors are being retracted. When the extendable floors 40 and 41 are completely retracted and the passenger doors 48 of the trains are closed, the curtain roofs are retracted to their'roof positions. The curtain roofs may comprise a metal material and may be rolled on rollers 49 and 50 as shown in FIG. 4.
FIG. 1 shows another feature of the invention wherein retractable air direction shifters 50 and 54 may be extended from trains 12 and 13 respectively to function as a wind buffer when the passenger bridge has been extended. The trains l2 and 13 may also be provided with removable front portions 52 and 53 respectively to deflect the wind. As shown, front portions 52 and 53-are substantially triangular in shape with their front portions, relative to the direction of travel, forming the hypotenuse of the triangle in order to push oncoming air to the side thereof.
FIG. shows a conveyer system which may be utilized to transfer goods between interconnected trains 12 and 13. Both main and local train cars are equipped with horizontal transversely extending endless belts 60 driven by drive wheels 61 powered by motors 62. These belts, wheels and motors form conveyers which are reversible in direction. By selecting the direction of rotation of conveyers on both trains simultaneously, an operator can transfer goods 63 either fromthe main to the local train or vice versa as previously discussed.
The operation of the railway system according to the transfer between the trains. After transfer is completed, the curtain roofs are extended to connect with their respective floors as the latter are retracted. When the retraction is completed, the curtain roofs are retracted to their rolled up position, and the interlock between the trains is broken. The main train then continues on its run.
In the case of transferring goods between trains, the conveyer system as described with'respect to FIG. 5 is actuated after interlock to effect the desired transfer.
It is thus seen that the invention comprises an effective and efficient means oftransferring passengers and- /or goods between a main train and a local train without requiring the main train to stop or'reduce its speed. Further certain safety precautions result from the invention as described herein.
