My invention relates, generally, to transporta- The above-mentioned copending application describes a transportation system in which two or more continuous, parallel platforms or trains are provided, one of which operates continuously at a high average speed, but not a constant speed, while the speed of the other platform varies in cycles between standstill, or a very slow speed, and a maximum speed which is equal to the minimum speed of the high-speed platform. Passengers are permitted to board the slowspeed platform while it is at a standstill. It is then accelerated while the high-speed platform is decelerated and when the two trains reach substantially the same speed, they run at substantially the same speed for a definite time to permit the interchanging of passengers between the two platforms. The highspeed platform is then ac celerated to its maximum speed and the slowspeed platform is deceierated to its minimum speed. at which it remains for a definite period to permit the loading and unloading of passcngers. The slow-speed platform is than accelerated and the cycle of operation is repeated. as described in my copending application, Serial No. 612,014.

An object of my invention, generally stated is to provide means for propelling the vehicles of a continuous transportation system which shall be simple and efficient in operation and which may be economically manufactured and installed.

A more specific object of my invention is to provide for propelling the vehicles of a continuous transportation system by stationary motors mounted independently of the vehicles.

Another object of my invention is to provide for transmitting the power of the propelling motors to the vehicles of a continuous transpor- According to my invention, the vehicles of a continuous train are propelled by an adhesive or roller drive which comprises a flanged rail fas- (Cl. l0425) tened to the under side of a fixed axle on each platform and two vertical shaft rollers, one on each side of the web of the flanged rail. The rollers drive the rail through adhesion developed by air pressure applied to roller bearings beneath the driving rollers. The shafts which drive the rollers are geared to vertical shaft motors located in pits underneath the track. The motors are mounted on trunnions, permitting them to move laterally a small amount as the driving rail on the drive varies its position. Each motor unit, consisting of two or four motors, is assembled complete and mounted on a truck in order that the complete unit may be quickly removed from its position beneath the track without interfering with the operation of the train.

For a fuller understanding of the nature and scope of my invention, reference may be had to the following detailed description, taken in conjunction with the accompanying drawings, in which:

Figs. 7' and 8 are plan and sectional views, respectively, showing the manner of coupling the cars together and of attaching the driving rail to the axle of a car;

Figs. 9, 10, 11 and 12 are enlarged views showing details of the construction of the coupling device.

Referring to the drawings, and particularly to Figs. 1 to 4, inclusive, the reference numeral til designates a continuous platform or train which moves continuously at a high average speed, but not at a constant speed, and the reference numeral ll designates a transfer or slow-speed platform, the speed of which varies in cycles between standstill, or a very slow speed, and the minimum speed of the high-speed platform. The cycle of operation and the manner of controlling the operation of the trains by means of control apparatus I2, shown in Fig. 2, are fully described in my copending application Serial No. 612,014 and, therefore, will not be described in detail in this application.

The high speed or carrying platform Iii may preferably consist of a continuous train of enclosed cars l3, provided with seats it, or it may be constructed in any other desired form. The slow-speed or transfer platform 5 i may consist of a continuous train of open vehicles 86, as the passengers remain on this platform only during a short interval when transferring to and from the high-speed train. Theslow-speed platform is provided with a guard railing IE5 for the protection of the passengers and a plurality of posts I! to assist the passengers in supporting themselves during the acceleration of the train. The cars are provided with doors which are automatically opened at the proper time to permit the transfer of passengers, as described in my copending application Serial No. 612,014.

As shown in Fig. 2, the cars are mounted upon axles l8 having wheels it which run on roller bearings. Each car is provided with only one axle which is under one end of the car; the other end of the car is carried on the axle end of the next car, as shown in Fig. 5. A T-rail 24, which is fastened to the under side of the axles on each car, runs between pairs of rollers 22 which are driven by electric motors disposed in pits underneath the tracks.

The rollers 22 are mounted upon vertical shafts and drive the rail 2| through adhesion developed by air pressure applied to ball or roller hearings on the shafts beneath the driving rollers. The propelling motors are located in driving stations which may be spaced at suitable intervals throughout the entire system in accordance with the power required to operate the platforms. Inasmuch as the equipment in all stations is the same, that in one station only will be described.

The shaft of each roller 22 of a pair of rollers that drive the high-speed platform ill is geared to two vertical shaft motors 21-; which are mounted upon a base plate 25, as shown in Figs. 2 and 1. The same base contains bearings for the motors and for the driving shaft. A gear case 25 is bolted underneath the base plate. The gears run in oil which may be circulated through the roller bearings in the base.

The motors are mounted on trunnions 26, thereby permitting them to move laterally a small amount as the driving rail 2i varies its position. The trunnion supports are mounted upon a truck frame 2? which is provided with wheels 28. A complete motor unit consisting of four motors for the high-speed platform, or two motors for the slow-speed platform, may be readily rolled out of place in case of a fault in one of the motors and another unit connected in its place. When the unit is in the proper position underneath the track the truck frame 21' may be raised by means of jack screws 29 to a position in which the rollers 22 will engage the rail 2! and then blocked in place by beams 3i, as shown in Fig. 4. or by any other suitable means.

In order that sufiicient adhesion may be maintained between the rollers 22 and the rail 2! to drive the cars without slippage, the rollers are firmly held against the rail by means of air pressure. A large roller or ball bearing 32 is mounted upon each shaftunderneath the driving roller. An air cylinder 33 is mounted upon each bearing and each cylinder contains a piston 35 which is connected to the bearing on the shaft of the opassesseposite roller 01 each pair. By applying air pressure to the pistons in the cylinders the rollers 22 may be firmly pressed against the rail 2| to pre vent slipping of the rollers on the rail. If it is necessary to remove one of the driving units the air pressure may be quickly released to disengage the rollers from the rail 2|, the bars 3| may then be removed and the truck 21 lowered by means of the screws 29.

As shown in Figs. 3 and 4, tie rods 35 are also connected between the bearings 32 and the walls of the station in which the motors are located in order to overcome the reaction of the roller drive and prevent longitudinal movementof the driving rollers.

In the illustrated embodiment of the invention, a driving unit for the slow-speed platform II is similar to one for the high-speed platform except that only two motors 36 are provided in each unit in place of four. fore, geared to only one motor. The motors are mounted upon a truck 27, in the same general manner as the motors of the high-speed unit, by means of trunnions 26. The truck may be raised and lowered by jack screws 29, as previously described. The driving rollers 22 are compressed against the T-rail by air pressure in a similar manner as the rollers of the high-speed unit. the shafts of the rollers being provided with ball or roller bearings 32 and air cylinders 33.

As shown in Figs. 5 and 7, each car or section of the platforms has only one axle, which is fixed. and two wheels, each running on its own roller bearings. The axle is under one end oi the car and the other end is supported by the axle end 1 of the next car. One end of the body of each car is mounted on an axle 8| by means of cllip tical springs 32 and the other end is pivotally supported on the end of the next car in a manner to permit free movement in both a vertical and a horizontal direction, thereby permitting the cars to readily negotiate curves or uneven places in the track. It will be noted that the cars may be readily disconnected by lifting the end of the car to raise the coupling member or hook 38 out of the pocket 39 in which it rests.

As previously stated, the cars or platforms are driven through a T-rail 2| which is secured to the underside of the axles 4|. The rail ii is divided into sections which are the same length as the cars. One end of each section of the rail is attached to the axle of the car and the other end is supported on the end of the rail on the next car in much the same manner as the body of the car is supported. Referring to Fig. 8 it will be seen that the ends of each rail section are cut at an angle of approximately 45 degrees in order to make continuous contact with the driving rollers.

As shown, particularly in Figs. 9 to 12, inclusive, a rail coupling comprises a ball and socket joint 33, the parts of which are carried in a casting id which may move a small amount relative to a container casting 55 which is securely fastened to one end of a section of the driving rail 28. A pin 46, which fits into the ball 43, is secured in a casting 61 which is fastened to the other end of a rail section. Accordingly, one end of each rail section is carried by the casting 35, which is attached to the axle 4 i, and the other end is carried by the casting 41 and the pin 56,

which fits into the ball of the ball and socket joint on the next rail, as shown in the drawings.

In order to support the one end of the rail in case the end of the car is lifted out of place to disconnect it from the train or to prevent the Each driving roller is, thererail from dropping in case the coupling bros-ills, a supporting member ill, Fig. ll, elite up werdly from the casting ll to the body of the car. As shown, the lower portion of the member M passes through a pocket so in the casting ill and the upper end is fastened to time our coupling member.

In order to permit the distance between the supports for the couplings to be adjusted with e view to adjusting tile lengiil of the core to moire the length of the train equal to ibe length of the track and also to provide resiliency in the driving system, a plurality of loci springs Eli are inter posed between the cestirlg 3%, which carries the ball i3, and the container casting fil as shown in Figs. 16) and 12, in c manner to permit the costlog it to move slightly with respect to the costing :35.

As shown, the casting cs is provided with en upwardly-extending projection which is disposed between the leaves oi lube springs 55 which,

are retained in the container ousting Gil by is cover plate 53. The casting so is, therefore, permitted to slide back and forth a, limited amount because of the flexibility oi the springs bi. if it is necessary to very the length of the cars, in order to make the length of the train equal to thot of the truck, one or more spring leaves may be transferred from one side to the other oi the projection '62 in order to increase or decrease time length of the train,

Referring particularly to Figs. ill and 12, it will be seen that the axle ll oi the car is retained in position in a pocket oil in the costing es by means of a cover plate 55 end a plurality of edjusteble set screws 55 which are provided with loch cuts 57. In order to dessrlen the noise sud also to allow ileiubility, insulating cushions lib, composed of rubber or other resilient material, are interposccl between the axle and the retaining cups in which the heads of the screws 5% are rested, as shown in Fig. 12. A ill is mso iriterposed between the cover plate curl the top oi the axle (it. For this -:ler power is transmitted from the rail ill to rho axles curl practically no vibration or noise is transmitted be the car bodies.

As shown in Figs. 8, the axle ll is held at right angles to the rail 36 by means of e, yoke which comprises two rods 32. One end of each rod is connected to one of wheel bearings and the oiber curls are connected to the rub at er. The rods may be adjusted to correct the po= sition of the sxie with respect to the rail 20.

While I have illustrated my transportation systerm as being adapted for use in subways, it will be readily understood that it may be easily constructed on the surface, or it may run overhead. between or through the tall buildings in our large cities, fumisl a, means of quiclrly and safely transporting a. large number of people over any desired distance, thereby relieving the present congested condition on our city streets.

From the foregoing description, it is evident that l have provided a, transportation system which is simple and economical in operation and which has a greater capacity than any of the present systems. The continuous transportation systemherelu described mey'bc operated safely and quietly, and it provides a convenient means s of transporting a large number of passengers luv-H5130, oi the invention may be made without departing from the spirit and scope thereof. it is intended that all matter contained in the above dewriptlou or shown in the accompanying drawings shall be interpreted as illustrative and not in a, limiting sense.
