This application filed @ctober 5,

1929. Serial No. 397,711.

This application is a substitute for applicants prior application, Serial No; 151,423, filed November 29, 1926.

This invention relates to means for supporting or hanging cars from trucks of the monorail type, and more particularly to stabilizing mechanism or means for maintaining or tending to hold the trucks and cars in normal or predetermined positions with respect to each other. In other words, the present invention is intended to provide means for permitting the truck to have such universal movement with respect to the car or hanger as may be necessary for the proper operation thereof, such as when the car is passing around a curve or over vertical deviations or changes in the track or when the car is subjected to lateral swaying due to wind pressure or the like.

The principal object of this invention is to provide an improved hanger for monorail cars; while other objects are to provide resilient means tending to hold the car and truck or trucks in predetermined positions; to provide springs or equivalent yielding means tending to hold the truck in normal position with respect to the car; to provide a universal or ball and socket hanger joint between the hanger and truck; to provide a hanger having universal movement with respect to the truck and springs or the like tending to hold the hanger in normal position; and to provide such other novel features and improvements in construction as will appear more fully from the following description.

In the accompanying drawings illustrating a preferred form of my invention;

Figure 1 is a side view of a section of a monorail track shown on a curve with two cars suspended therefrom;

Figure 2 is a plan view of the apparatus shown in Figure 1;

Figure 3 is an enlarged plan view of the truck and hanger;

Figure l is a side view of the same;

Figure 5 is a cross sectional View taken on the line 5-5 of Figure 4;

Figure 6 is a sectional View taken on the line 66 of Figure 5;

Figure 7 is a sectional view taken on the line 77 of Figure 5; and

Figure 8 is a sectional view taken on the line 8-8 of Figure 5.

Some of the parts shown in these different views are illustrated diagrammatically and other parts are broken away or omitted for convenience in illustration. Each car may be supported by any desired number of hangers and trucks but as these parts are all substantially duplicates, the description will be limited to a single one.

In general, the cars 10 are provided with hangers 11 which support them from trucks 12 adapted to be supported by a rail 18. This rail is supported in any suitable manner, as by means of beams 15 which in turn are carried on any suitable track supports which are not shown as they form no part of the pres entinvention. It is readily apparent. par ticularly as shown in Figures 1 and 2, that when a monorail car or train passes around a curve, the trucks will swing or rotate with respect to the car body, about a vertical axis as the hangers are rigidly secured to the body. At the same time there is a tendency, due to centrifugal force, for the body to swing ith respect to the trucks about a horizontal axis, assuming that the truck is to remain sub stantially vertical or normal to the track. ll will also be noted that when the truclr passes over vertical curves or deformations in the track, there is a tendency for the truck to swing, with respect to the car, on a horizontal axis at substantially right angles to the car. On account of these movements, as well such other movement as may be desired be tween the truck and the hanger or car body, 1 have provided a universal joint or connection between the truck and hanger and resilient means tending to hold the truck and hanger in n'edetermined position with respect to each other.

The hanger 11 as shown particularly in Figures 5 and 8 is of substantially U-shape and is connected at its lower end with beams or frame members 16 which support the car or load. The upper end of the hanger comprises, or is secured to a post or arm 17, the lower end of which is provided with a socket -or bearing portion 18 which is preferably of spherical form and which engages with a similarly shaped spherical bearing 19 which is carried, or formed integrally with, a bracket 20 which is rigidly secured to the truck frame. This is conveniently done by bolting or riveting the bracket to cross bars or frame members 21 which are secured to the longitudinal truck beams 22. The upper surface of the socket or bearing member 18 is also preferably made curved or spherical and is engaged by cap or shroud members 23 and 24: which are secured respectively to the beams 22 and the bracket 20 and which complete the universal joint and tend to hold the hearing members together, sufficient clearance being provided to allow for the necessary movement between these parts.

The upper end of the post or arm 17 has a spherical head orball 25 which fits in a socket 26 formed in the adjacent sides of blocks 27 which fit freely in guideways 28 so that they may have bot-h lateral and longitudinal movement therein. These guide ways are formed by plates 29 and cross bars 30 which are rigidly secured to the upper longitudinal truck beamsBl, as shown in Figures 5, 6, and 8. The blocks 27 are normally held in central position in one direction by opposed coil springs 32. They are also held yieldingly in normal position in i the opposite direction by means of opposed leaf springs 33 which engage with the bars 30 and with guide strips 34: which in turn engage with the blocks 27, as shown particularly in Figure 6.

The trucks 12 are provided with track wheels 35 which are mounted in the trucks in any desired manner, and the trucks may be provided with any suitable motive power (not shown).

From this description, it will be seen that I provide a universal yielding joint or connection between thetruck and the car which will permit of any necessary or desired movement between these parts while at the same time tending to hold them or return them to normal position with respect to each other. It will of course be apparent that changes may be made in the details of construction and arrangement of the parts for adapting the mechanism for difierent uses or conditions, as for instance in the construction of freight or industrial cars as well as passenger cars, and therefore I do not wish to be limited to such details of construction or arrangement of parts, except as specified in the following claims, in which I claim:

1. The combination with a monorail truck and car hanger having a universal joint con nection therewith, of means for resiliently holding the truck and hanger in predetermined position with respect to each other.

2. The combination with a monorail truck having a spherical bearing secured thereto,

of a hanger having a substantially vertical upper portion with a socket fitting over said bearing, means tending to hold the socket in engagement with the bearing, the upper portion of the hanger having a hearing at the top thereof, and a plurality of springs interposed between said bearing and the truck frame and tending to hold the hanger in pre determined position with respect to the truck.

3. The combination with a monorail truck, of a substantially scpherical bearing secured thereto, a substantially til-shaped bracket adapted to be supported by the truck and to support a car centrally below the truck, said bracket having a socket engaging with said bearing and having an upwardly projecting arm with a substantially spherical hearing, blocks engaging with said bearing, and pairs of transverse and longitudinal springs coacting with said blocks and tending to hold the same in central position.

4. A monorail railway apparatus comp ising a piurality of trucks, each truck having a pair of wheels adapted to operate on an overhead rail, a car, hangers secured to the car and having universal joint connections with the trucks, and resilient stablizing means tending to hold the trucks and car in predetermined position with respect to each other. 7

5. A railway comprising a single supporting rail, trucks having wheels for engaging with said rail, a car, hangers secured to said car, universal joint connections between the hangers and the trucks whereby each truck is permitted a limited amount of movement in all directions with respect to the hanger, and spring means tending to hold each truck and hanger in iu'cdctermincd position with respect'to each other.

6. The combination with a truck having its wheels in alinement for a monorail track, of a hanger'having a universal connection therewith, a car supported by the hanger and resilient means tending to hold the truck in substantially normal position with respect to the car.
