Description:

This invention relates to overhead railways of that type embodying a stationary monorail supporting structure and cars suspended therefrom.

More particularly, the present invention relates to overhead railways of that type in which the monorail supporting structure includes a row of towers, each carrying an upper cross arm, from the ends of which are suspended a pair of monorails, and wherein monorail cars suspended from the respective monorails are adapted to travel on the latter in opposite directions.

An object of the present invention is to provide, in an overhead railway of the above kind, an improved monorail supporting structure.

Another object of the present invention is to provide, in an overhead railway of the above kind, improved traction and driving means for suspending the monorail cars from the respective monorails so as to effectively guide the cars around curves without undue lateral swaying and without the use of additional guiding means between the towers and the bottoms of the respective cars.

Still another object of the present invention is to provide improved guiding and traction means of the above kind that includes front and rear swivelled six-wheeled trucks for each monorail car, each truck including forward horizontal guide wheels engaging opposite sides of the monorail above the bottom flanges of the latter, and front and rear suspension or traction wheels riding on the upper surfaces of said bottom flanges of the monorail.

Still another object of the present invention is to provide suspension and driving means for a monorail car wherein the swivelled trucks have laterally swingable mounts for the front guiding and traction wheels and for the rear traction and driving wheels thereof, and wherein manually operable means is positionable at the outer side of any desired one of the mounts for swinging it laterally outward to facilitate repair or changing of tires and other repair work thereon.

Other objects and features of the invention will become apparent from the following description when considered in connection with the accompanying drawings, and the invention consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the drawings and claims.

In the drawings, wherein like reference characters indicate corresponding parts throughout the several views: Figure 1 is a fragmentary side elevational view of a rail supporting structure and cars suspended therefrom in accordance with the present invention.

Figure 2 is an enlarged transverse sectional view thereof taken substantially on line 2-2 of Figure 6 1.

Figure 3 is a fragmentary enlarged side elevational view of the car and adjacent parts of the supporting structure shown in Figure 1.

Figure 4 is a top plan view of the construction shown in Figure 3.

Figure 5 is an enlarged fragmentary transverse section taken substantially on line 5-5 of Figure 3, and illustrating one of the wheel mounts of the rear driving and supporting wheels of the rear truck of the car shifted to outwardly swung position for convenient repair or replacement of the tire of the associated wheel by means of a wheel mount swinging device installed and constructed in accordance with the present invention. Figure 6 is a side elevational view of the wheel mount swinging device per se, drawn on an enlarged scale.

Referring in detail to the drawings, the present railway includes a row of towers 5, each carrying an upper cross arm 6, to the ends of which are secured the adjacent portions of longitudinal flexible supporting elements 7 that extend between corresponding ends of the cross arms 6 in downwardly arched or curved shape as shown in Figure 1 from each tower to the next, and that may consist of a pair of cables 8 disposed side by side and suitably secured at 9 to the undersides of the ends of the cross arms 6. Cables 10 are looped over the supporting elements 8 at suitable intervals along the length of the latter between the towers and attached to the elements 8 by welding or the like. The lower ends of the looped cables 10 are suitably anchored to lateral flanges or ears I provided on the upper edges of monorails 12 that have bottom flanges 13. The monorails are thus flexibly suspended by the cables 10 from the supporting elements 8, and said cables 10 may be suitably interbraced by cross brace elements 14 between adjacent ones of the same to restrain the monorails against longitudinal movement. Lateral swaying of the monorails is prevented by means of rigid arms 15 projecting laterally from the towers 5 and anchored to certain of the ears 11 of the monorails. At opposite sides of the vertical webs or members of the monorails 12, the said vertical webs or members are provided with insert strips 16 of hard wear-resisting metal on which horizontal guide wheels of the car suspension means are adapted to ride, as will later be described. Similar inserts 16a are provided in the upper surfaces of the flanges 13 of each monorail on which are adapted to ride the traction and driving wheels of the car suspension and guiding means, as will also be made more clearly apparent.

As illustrated more clearly in Figure 2, a car A is adapted to travel on one of the monorails in one direction at one side of the row of towers, while another car A' is adapted to travel on the other monorail at the opposite side of the row 1 of towers, thereby providing for two-way traffic.

Each car includes a body of elongated form suspended from the associated monorail by means of front and rear swivelled trucks T and T', respectively, of generally similar form and construction. Each of the trucks includes a longitudinal member 17 having cross members 18 at the opposite ends thereof and provided intermediate the ends of the same with a hub It that is rotatably mounted upon a spindle 20 fixed to and projecting upwardly from the top of the associated car. The hub 19 turns on the spindle 20 to permit swivelling of the truck about a vertical axis so that the trucks may turn for convenience in negotiating curves or turns in the monorail. Rigid with and projecting upwardly from the ends of the crossed members 18 of each truck are the lower sections 21 of front and rear wheel mounts that include laterally swinging upper sections 22 hinged at their lower ends to the lower sections 21 as at 23. The swinging sections 22 have inwardly projecting shafts 24 on the inner end portions of which are mounted the vertical traction wheels 25, and the adjacent ends of the mount sections 21 and 22 have aligned apertures as at 26 to receive removable pins by means of which the sections are releasably retained in aligned relation, with the associated wheels 25 engaging the inserts 16a in the upper surfaces of the bottom flanges 13 of the monorail. By removing the pins at 26, the upper sections 22 of the wheel mounts may be swung laterally outwardly to facilitate change of tires of the wheels 25 or repair of parts of the mounts in an obvious manner.

As shown in Figures 3 and 4, the front wheel mounts of the trucks have forwardly projecting arms 27 on the laterally swinging upper sections 22 thereof, and journaled on the forward ends of these arms 21 are horizontal guiding wheels 28 that ride on the inserts t6 of the vertical webs of the monorails. Also, the shafts 24 of the rear laterally swinging wheel mount sections 22 of the rear truck T' constitute the drive shafts of electric motors 29 that are fixed on the associated mount sections 22 and that may be suitably controlled from the driver's seat in the forward end of the associated car A or A'. Thus, the rear wheels 25 of the rear truck T' are utilized to drive the car for effecting travel thereof along the monorail, and any suitable braking means may be provided for bringing the car to a stop wherever desired.

Means is provided for facilitating lateral outward swinging of the upper sections 22 of the respective wheel mounts, and such means consist of a supporting post 30 having a winding drum 31 journaled in the upper end thereof and provided with an operating crank 32, a flexible member or cable 33 being adapted to be wound on the drum 31 and provided at its free end with a hook 34 engageable in an aperture 35 of the sections 22 of the wheel mounts. In order that the means for swinging the upper sections of the wheel mounts 22 may be selectively utilized with respect to each swinging section 22 of said wheel mounts, the car A or A' is provided in the top with a socket as at 36, at the outer side of each wheel mount, adapted to removably receive the lower end portion of the post 30. The upper portion of the post 30 is inclined upwardly and outwardly so as to position the drum 31 outwardly of the associated mount section 22. Thus, when the mount swinging means is positioned outwardL0 ly of any mount, the hook 34 may be engaged in the aperture 35 of the section 22 thereof, and upon rotating the crank 32 in a proper direction, the cable 33 may be wound on the drum 31 to swing the adjacent mount section 22 outwardly to the position shown in Figure 5. When in this section, the desired repairing or tire-changing jobs may be readily accomplished.

It will be apparent that the present invention contemplates the provision of guiding and supporting wheels for the cars which are equipped with pneumatic tires so as to provide for shockfree travel, convenient and effective means being provided whereby the tires may be conveniently changed or repaired. When any wheel mount is swung outwardly, as shown in Figure 5, the remaining wheel mounts will serve to effectively suspend the car while tire repairing or changing, and the like, is being accomplished.

From the foregoing description, it is believed that the construction and operation, as well as the advantages of the present invention, will be readily understood and appreciated by those skilled in the art.

It will be apparent that I have provided a simple and efficient means for carrying out the stated objects of the invention.
