Still another object of the invention is to provide in a car of the class described improved guide mechanism which is adapted to'cooperate with aguide rail on the track to hold the car against lateral movement.

A still further object of the invention is to provide an improved driving device for the car, this driving'device being adapted to cooperate with' a driving chain.

Still another object of the invention is to provide an improved general arrangement of parts whereby the guide mechanism the driving device and thesafety device are lo cated in improved relationship.

A further object of the invention is to provide an improved combinational relationship between a car embodying the invention and a track of peculiar type adapted to cooperate with the car.

Still furtherobjects of the invention will be apparent from the following specification and claims. 7

In the accompanying drawings, I have shown certain embodiments of the invention which have been selected for purposes of illustration, but it will be understood that the drawings are not to be construed as defining or limiting the scope of the invention, the claims forming a part of the specification being relied upon for that purpose.

It will further be understood that the track structure which is shown in part does not of itself constitute a part of the present 1 invention, this track structure forming the subjectanatter of my copending application for coaster track structure filed Jan. 16, 1926, Serial No. 81,733..

Of the drawings:

Figure 1 is aplan view of a train of coaster cars embodying the invention, the body superstructure being omitted for the sake of simplicity;

Fig. 2 is a side view of one of the cars;

Fig. 3 is an end view of one of the cars and a transverse section of the track;

Fig. 4 is an enlarged plan view of the chassis of one of the cars, the superstructure being omitted for the sake of clearness Fig. 5 is a side view of the chassis shown in Fig. 4, some of the parts being broken away to show other parts more clearly;

Fig. 6 is a transverse sectional view taken along the line 6+6 of Fig. 4;

Fig. 7 is a fragmentary plan View showing parts of the driving and connecting mechanism for two adjacent cars;

Fig. 8 is a side view, partly in section, of the parts shown in Fig. 7 and Figs. 9 and l0 are views similar respectively to Figs. 2 and 3, but showing an alternate embodiment of the invention.

Figure 1 represents a train of cars 1, 1, and 2, 2, embodying the invention, four of such cars being shown. It will be understood that all of the cars are or may be of the same construction. Preferably, however, I prefer to provide each alternate car, that is, the cars 1, 1 as shown, with driving and safety devices which will be hereinafter more fully described. For the sake of economyfand simplicity, these devices may be omitted from the remaining cars 2, 2.

Each of the carscomprises two sections 3 and 4 which are relatively movable about a central longitudinal axis. The sections 3 and 4 are provided respectively with main supporting wheels 5, 5, and 6, 6. The two sections are provided respectivelv with seats 7, 7, and with protective hand rails 8, 8. Inasmuch as the two sections 3 and 4 are relatively movable about a central longitudinalI axis. it will be apparent that the car is well adapted to accommodate itself to variations in the inclinations of the respective rails such as are to be found in coaster railways, particularly at points where there are changes in the track curvature.

The details of construction of the car chassis are more clearly shown in Figs. 4:, 5 and 6. As already stated, the chassis is particularly adapted to be constructed entirely of metal, and the preferred metallic construction will now be described in detail. It will be apparent that the two sections 3 and 4. of the car are of substantially the same construction except for the fact that they are reversed.

Each or" the sections 3 and 1 comprises a rectangular framework which preferably includes longitudinal side members 9, 9, and transverse members and 11. These members may be structural steel sections, such as channel bars, and they may be suitably connected together at the corners by means of angle bars 12, 12. Preferably a third transve'se member 13 is provided adjacent the member 10, and short longitudinal members 1 1, 1 1, are provided extending between the members 11 and 13.

Secured to the respective members 9 and 1e at the two sides of the frame are bearing brackets 15, 15, for themain wheels. These brackets are suitably secured in place, as for instance by means of the bolts 16, 16. Suit-' aoly located in transverse holes in each of the brackets 15 is a bearing pin 17 on which rotatably mounted one of the car-supporting wheels 5-5 and 66. Preferably and shown in Figs. l to (3, these wheels are or the plain unlianged type.

Extending longitudinally between the transverse members 11 and 13 and secured thereto are bolsters 19, 19. Secured to these bolsters are bearing brackets 20 and 21, which are similar in construction but which are oppositely located with respect to the bolsters. These brackets 20 and 21 are provided with recesses adapted respectively to partly receive guide wheels 22 and 23. Vertical bearing pins 24, 2a, are provided for these wheels, these bearing pins being seated in suitable apertures in the bracket.

In Fig. 6, l have shown the chassis in the position which it assumes on the track. It will be seen that rails 25, 25, are provided for supporting the main wheels 55 and 6-6 and that a guide rail 26 is provided for engaging the guide wheels 22 and 23. The guide rail 23 preferably comprises two parallel planks or two series of superposed bars 2", 27, secured to central supporting bars 28. it earing strips 29, 29, may be provided to contact with the wheels 23 and 24. It will be seen that the wheels 23 and 2 in cooperation with the guide rail serve to hold the car in proper relation to the track and to prevent it from moving laterally with re spect thereto.

F or connecting together the two main sections 3 and 4: of the chassis, there is provided a longitudinal bar or heavy tube 30 which is of circular cross section and which extends the entire length of the car. This bar extends through suitable apertures formed in the transverse members 10, 1O, 13, 13, and i '11 1 Pretera ly as shown more clearly in Fig. 3, bearing blocks 31, 32 and 33, are provided at the respective transverse bars 10, 13 and 11, these blocks being provided with suitable apertures through which the bar 30 extends. The bearing blocks for one of the sections, as for instance the section 1, are secured to the bar 30, by suitable means, as for instance set screws Located between the central bearing blocks 31, 31, and surrounding the bar 30 is a washer 34 which serves to hold the blocks 31, 31, and the transverse members 10, 10, in spaced relation. Secured to the ends of the bar 30, preferably by icing threaded thereon, are collars or nuts 35 and 36 which abut against the respective end bearing blocks 33, 33. Taper pins 35, 36, may be provided for preventing the two collars 35 and 36 from turning.

From the foregoing description it will be seen that the bar 30 serves to connect the two main sections oil the frame but at the same time permits them to turn relatively to each other about the axis oi the bar. The washer serves to maintain a proper spacing between the two frame sections and also serves as a thrust hearing when relative movement takes place. The two collars or nuts 35 and 36 serve to prevent the two frame sections from being longitudinally separated.

In order that the cars may be suitably driven by means of a chain, 1 provide them, or at least some of them, with driving de-v vices adapted to engage a chain. As shown in Figs. to 6, a collar 37 is splined on the bar 30 and carries a pivoted dog or sprag 38 which is adapted to be engaged by one of the shoulders of a chain. Preferably a pipe 39 surrounds the bar 30 and serves as a spacing member between the collar 37 and the transverse member 13. A. heavy coil spring d0 surrounds the rod 30 and is interposed. between the transverse member 11 and the collar 37. It will be seen that when the sprag 38 engaged by the chain, the driving of the car is etlected through the spring which thus serves as a shock absorber to prevent any undue shock when the sprag first engages the chain.

As a safety device to prevent backward movement of the car in case of accident of any kind, I provide a dog or sprag 41 which is secured to the transverse member 11 adjacent the bar 30. This safety sprag 11 is adapted to engage a suitable toothed detent device which is arranged in suitable position along the track.

For the purpose of carrying the guideway for the actuating chain and for also carrying the safety detent device, I preferably provide a member 42 which forms a iamega m part of the guide rail 26. This member 42 is preferablyin. the form of a plank which overlies the supportingbars 28i and the longitudinal guide bars 27, 27 Preferably this projects laterally in: the form of ledges at both. sides of the bars 27, 27. These lateral projecting ledges have the additional advantage of serving as a safety means to engage the guide wheels 22 and 23 to prevent the car from jumping the track or tipping. over sideways in case of any emergency.

As shown in Fig. 6, the plank: 42 carries a channel. bar 43 whichser-ves as a guide for a drive chain .44.. The plank 42 also carries .twoanglebars 45,45, so placed as to form a channel, betweenv which ektend transverse bolts .orpins 46 which serve assafety devices adapted to. be engaged by the safety sprag 41.

It is desirabletohave the connecting bar for the two main sections of the car chassis located at the center of the car. Inasmuch as the guiderail is used to supi port both the chain guide 43 and the safety retaining devices 45,145, and 46, 46,.the said guide ;rail is preferably. located a short distance to=one side of the center of the track, as :clearly shown in Fig. 6. The bolsters 19, 19, are correspondingly located so as to bring the guide wheels 22 and 23 into proper relation with the guide rail.

In order thatseveral, cars may be connected together to form a train, as shown in Fig. 1, I provide suitable coupling'devices. As shown in detail in Fig. 8, the nut is formed as a part of a ball socket 47, this socket being completed by a cap 48 held in place by bolts 49. A ball 50 fits this socket and this ball is carried by a stem 51 which is threaded into the end of the tube 30 of the next adjacent car. It will be seen that the coupling described permits adjacent cars to move relatively to each other in any direction. Any tube 30 can turn about its aXis relatively to the next adjacent tube and thus the cars can accommodate themselves to varying transverse inclinations of the track.

lVhen several cars are connected as shown, each alternate car may be provided with driving devices adapted to engage the drive chain; Preferably the distance from car to car is a multiple of the distance from shoulder to shoulder on the drive chain. In order to insure a gradual pickup of the load and a proper distribution thereof, the front car is preferably provided with a washer 52 and a corresponding shorter spacer 39 as shown in Fig. 4.' This construction displaces the sprag 38 toward the rear. The next driving car is provided with. a thinner washer 53' and a corresponding shorter spacer 39 as shown in Figs. 7 and 8. The third driving car (not shown) do'esnot have any washer corresponding to 52 or .53. The result is that the'front car 7 picks up the load first, thelo'ad coming on.

the second car on'lyafter the spring 40 of the first car has been compressed. The load comes on thethird car only after the springs of the first and second cars have been compressed. This construction. not only insuresthe: gradual picking up of the load, but in case of anyinaccuracy of construction. ofthe cars or of the chain it insures that at least apart of the'load will be taken by the front car.

In Figs. 9 and,10 I haveshown a construction whichissomewhat different from thatshown in the other views, the guide rail 26 and the corresponding guide wheels being omitted. The main wheels 5 and-6 are flanged, and the car is thus guided by the engagement ofthese flanges with the inner faces of the main. rails 25, 25. In order'toprovide a safety means to prevent the car from jumping the. track, each of the two girders is provided with an inward projection 54 which is adapted to'cooperate with downward projecting hooks 55, 55, secured to the car chassislVhat' I claim is:
