ROLLEE-GQAST ER RUNNING GEAR.

Application filed June 14,

To /I'ZZ whom it may concern I lie it known that l, Cirnis'rizin' it. i our, citizen of the United i rKiEllt 2 Brooklyn in the county of Kings and New York, have invented c tain new and useful Improvements in Roller- Coaster Running Gears of which the following is a specification.

The invention relates to roller coaster rijinni g gears of the class in which'the cars e arranged to run by gravity over a track comprising a series of horizontally and vertically curved sections. the former giving centrifugal or outward thrusts upon the cars and the latter downvi'ard and upward movements, the chief attraction or popularity in rides of this kind residing in the sei'isations or thrills occasioned by the velocity of the several movements.

The object of the present invention is to provide a suitably constructed running gear or combination of wheels and track structure to safely support the cars upon the track whereby a substantially increased velocity may be made both in the outward swinging action of the cars and the downivard and upward falling and rising movements thereof.

It further object is to provide means an.- tomatically controlled by the running gear for maintaining a substantially unifor trip-period for the several trains of cars running over the track at the same time, thus overcoming the common tendency of relative speed variation occasioned either by differences in load or in running gear construction.

A further object is to provide means for more effectively stabilizing the cars in their normal rapidly changing paths of movement by applying resistance directly at the points of greatest loads or thrusts.

A further object is to provide a track structure in connection with the car running gear whereby the latter may be covered or protected throughout its movements, and at the loading and unloading section of the track the gear may be partially uncovered to afford means for operating the car gates; the construction and operation of said gates being fully shown and described in my co-pending application, Serial No. 561,091, filed May 15, 1922.

For further comprehension of the invention, and of the obfects and advantages thereof, reference is ad. to the following 1922. Serial No. 568,185.

description and accompanying drawings, and to the appendedclaims in which the various features of the invention aremore particularly pointed out.

Figure 1 of the drawings is a plan view of the track structure formed in accordance with the present invention and showing more particularly the loading and unloadin portion of the track section.

Tigure 2 is a transverse section of the track structure taken along the broken lines 2-2, Fig. 1.

FigureB is a side elevation of a carshown in connection with the running gear and foot-treadle for operating the gates.

Figure at is an end view of the car shownon larger scale, partially in section, and in connection with the running gear and track structure.

Figure 5 is a detail side view of the wheel-frame with the wheels mounted thereon.

Figure 6 is a plan view of the latter.

Figure 7 is a transverse section of the wheel-frame along the broken line ,'?-7, Fig. 5, the wheels being shown in position.

As indicated in the drawings numeral 10 indicates a car-body, provided along its lower side edges with the corner binding an les 11, extending the full length of the car and around the forward curved portion thereof. Fixed to the opposite sidewalls of the car are the wheel-frames 12, having bottom flanges 13 adapted to engage the corner binders 11 and receive the weight of the car in connection with fastening bolts passing through the holes 14% of the frames, the latter comprisinga back plate or member 1.5, from which projects a guard flange or yoke 16. Traction or gravity wheels 17 are mounted on said frames within the yoke by means of the studs 18 provided with a reduced end 19 having threaded engagement with the back member 15, The wheels are loosely mounted on the studs in any apface comprising a curved plate 27 detachablv {retained in position by the screws 28;

(lo-operating with the several wheels is a track structure provided with main track plates 29 adapted to be engaged by the gravity wheels 17, the structure also being provided at opposite sides of the car with up right parts 30 and 32, the former parts being adjacent the rear side of the car and extending over the entire course of the main track and provided throughout its full length with the side thrust plates 31 adapted to be engaged by the upper level friction wheels 23. Also, withtbe exception of a portion around the loading and unloading station, the upright parts 32, adjacent the front or operating side of the car, extend over the entire course and are provided the full length thereof with the side thrust plates adapted to be engaged bythe upper level friction wheels 23. Adjacently disposed above the latter friction wheels at opposite sides of the car are upper level 'platfornis 34 extending the full length of the respective upright parts 30 and 32, and covering the wheel-frames 12, as clearly shown in' Fig. 4. The loading and unloading station comprises a low level platform 35 disposed with a curved outer edge adjacent the front or operating side of the cars, and extending on a downward grade betweenthe opposite ends, indicated at the points 36, ofthe upper level platform Fixed to the outer edge of this platform is a correspondingly curved side thrust plate 37 adapted to be engaged by the lower friction wheels 26, the lower thrust plate 37 being preferably disposed in vertical alinement with the upper thrust plates 33.

In the operation of the cars around the low-level or operating platform 85, the op-- posite side thrust plates 31 and 37' are engaged by their respective friction wheels to maintain the lateral position of the cars upon the ,traclgthe said position being held throughout the remainder of the track by the friction wheels 23 engaging the opposite upper sidethrust plates 31 and The relatively low position of the operating platform affords access for operating the gates of the several ears or trains by means of thefoot-treadle 38, which, in this position of the track, is ,uncovered and free to be operated by an ,attendant. For operating convenience, a running board 39 is fixed to the carbetweenthe wheehframes 12, below the foot-treadle 38, and substantially on a levelwith the operating platform The ends {of the running-board are provided with anchor-plates 5L0 connected by the screws 4-1, a d the anchor-plates in turn are secured to, t he upper side of the hubs 24; of the wheelby the studs 25 and nutsftQ, the lattell thelstu by thescrewed. As thus arranged platform. The

elnp covered by the washer 43 fixed to an attendant may eadily stand upon either the running-board or the opeiatg plat form or pass from one to the other in manually advancing the cars, operating the foot-treadle, or col ccting fares. i s the cars enter upon the operating platform in the direction shown by the arrow, they are brought to rest by suitably arranged braln ing mechanism, not shown, and. the gates are then opened for discharging the pas sengers. Upon reloading, the gates are locked and the train manually at vancedto thus avoid operating confusion, the speed controlling friction surfaces are provided upon the several wheel-frames. Under ordinary conditions in which the cars are left free to run over the tracks by gravity alone, it is found in practice that some trains or cars will make the trip over the several dips and rises more quickly than others, the more rapidly moving ones lifting themselves un der centrifugal action considerably off the track-plates at such points along the line, For overcoming this accelerated movement of the cars th friction surfaces are arranged to eng a as lower surface of the superposed p iorms and act thereby under the lifting action of the car to frictionally arrest the inc"ease of speed, the pee fr tional resis at the desired on the car and the bottom surface of the platforms also :"zcrveto prevent articles such as vi'ez iring apparel or bundles that may,' fall or be rnischicvously' thrown out of the car 'lroin landing among: the running gear and tracks and inter ering with the regular operation of the train. Also, the provisionof the guard or yoke ill upon the wheel-frame 12, not only prevents miscellaneous articles from becoming an tangled among the enclosed wheels, but also confines and overcomes the scattering lubricating oils applied upon the bearingsof the wheels or of the rainwater picked up by the latter. Furthermore the arrangement of the wheel-frames upon the cars serves to directly receive the operating lateral thrusts thereof and transmit them to the fixed side thrust plates.
