ANDREW G. SHERK, OF NEWARK, NEW JERSEY.

PLEASURE-RAILWAY.

To all whom it may concern:

Be it known that 1, ANDREW G. SHERK, a citizen of the United States, residing at Newark, in the county oil Essex and State of New Jersey, have invented certain lmprovements in Pleasure-Railways, of which the following is a specification.

This invention relates to that class of railways in which a car having a truck constantly traveling forward on parallel tracks is provided with a body portion adapted to rotate or to be rotated at predetermined intervals.

The objects of the invention are to secure an improved construction of means for rotating the body portion of such a car; to secure stability and safety and to gradually impart to the body of the car its rotary motion 5 to provide locking means for holding the car againstinadvertent rotation to provide operating means for simultaneously releasing said locking means and rotating the can-and to obtain other advantages and results as may be brought out in the following description.

Referring to the accompanying drawings, in which like numerals of reference indicate the same parts in the several figures, Figure 1 is a front elevation oi a car embodying my improvements, with the track in cross-section, and Fig. 2 is a plan of the same; Fig. 3 is a vertical longitudinal section of the car taken on line 3, 3, Fig. 2, and looking in the direction indicated by the arrow; Fig. 4 is a plan view of certain mechanism for locking the car body against rotating, and Figs. 5 and 6 are side and front views, respectively, of the same; Fig. 7 shows in side elevation a modified construction of friction wheel, and Fig. 8 illustrates in side elevation a modified form of friction board; Fig. 9 is a diagrammatic plan oi a section of the track illustrating the disposition of the friction boards.

1n said drawings, 10 indicates a car of my improved construction, and 11 a depressed track of usual construction for the same. Said car comprises an upper body portion 12 and a lower truck 18, said truck having at its-opposite side edges, near the front and rear, brackets'14 in which are hinged arms 15 carrying outwardly and downwardly facing traction wheels 16 and 17, respectively. These brackets, arms and wheels are of ordinary and well-known construction, so that the truck of the car travels along the track 11 as is usual in such railways.

The body 12 is adapted to receive the passengers, and is rotatably mounted upon the truck 13 by a central king bolt 18 or other equivalent means. The said body is preferably circular in form, as shown, and is provided with seats oll any suitable kind, as indicated at 19. Radially outward from the said king bolt 18, the body 12 rests at its under surface upon rollers mounted in the platheld level while at the same time permitted to rotate i'reely. Ol' these said rollers, some, as marked with reference numeral 20, serve only to support the body of the car, extending only slightly if at all below the platform 21 oil the truck. Two of the rollers, however, marked 22, are ol' larger diameter, so as to be pivoted in brackets 23 upon the bottom ol the platform 21 and extend a considerable distance beneath said platform, as well as reaching upwardly through it into engagement with the car body 12. These two rollers 22 are arranged in planes extending longitudinally ol the car and at opposite sides thereol' midway olI its length, preferably. The car body 12 is thus adapted to rotate upon its king pin 18, il' either ol the rollers 22 revolves, and in either direction according to which roller is turned. Furthermore, it will be noted that the said rollers 22 have smooth peripheries, as opposed to gear wheels or star wheels, and thus motion is transmitted by them to the car body to turn the same, frictionally, and not positively. By this means, the car body 12 is not started rotating with a suddenness and vshock which is both disagreeable and dangerous, but the rollers and body portion will slip at their point oi engagement until the body part has approximated the speedoi the rollers. The rotation of the car body is thus started or produced gradually and evenly. ln order to rotate the said rollers 22, one at a time, so as to cause the car body 12 to revolve, the same are adapted to have brought into engagement with their lower edges certain portions oi the track or surface over which the car is traveling, so that the irictional retardation will cause the roller to rotate. ln the drawings, 1 have shown this accomplished by iloor ol' the track and extending longitudinally thereo'l'. These Afriction boards are located at those points along the track where it is desired to have the car turn, and are form oi the truck, and thus the said body is means oi' friction boards 24, raised from the pendent of the truck of the car.

given length according to the duration of turning desired. The boards project sulficiently above the track to engage the rollers 22 with just enough friction, and the direction in which the car is to be turned by a given friction board is determined by the side of the track at which the friction board is placed. The ends of the friction boards are preferably beveled or inclined as at 123, to insure their gradual engagement with the rollers 22, and thus further avoid sudden shock to the car in starting its rotation.

Under some conditions, friction rollersv25 may be pivoted in boxes 26 which are slidably and resiliently supported in the brackets 27 by springs 28, as illustrated in Fig. 7,

and thus the friction roller allowed a certain.

amount of movement to adjust itself inde- Adjustability of the engagement of the rollers with the friction boards may further be secured by supporting said friction boards upon springs, as shown in Fig. 8. Here 29 illustrates a friction board having pins or feet 30 passing downward through perforated guide strips 31, 32, and having on themselves nuts 33 which can bescrewed up or down. Betweenl each of these nuts and a fixed stop, as the guide strip 32, is arranged a spiral spring 34 upon the pin 30 and which tends normally to hold the friction board upward, while not preventing its slight depression if necessary when the friction roller of the car engages it. Obviously, by this construction, the friction board can be adjusted up and down without disturbing the tension of the supporting springs 34.

At such times as the car isvnot rotated by the friction boards described, it is desirable tolock it against rotation, since it might inadvertently turn in al dangerous manner at times, as for instance onv a sharp curve or on an incline, because of the unequal distribution of the weight ofv passengers around the center. My invention therefore includes means for locking the car against rotation when desired, and such means are automatic in any suitable way so that when the car is not in engagement with the friction board it will be locked against turning. The particular locking means of that type which I have shown inthe drawings comprise gripping arms 35, 35 suitably curved to grasp between themselves the king bolt 18 and being provided thereat with friction surfaces 36. These arms lie horizontally upon the platform 21 of the truck, fulcrumed upon'a common pivot 37 thereon at the rear of the king bolt, and having their forward ends extending substantially parallel toward the front of the car as at 137, 137.r These ends 137 are slotted to receive a horizontal guide bar38 hxed upon the truck in brackets 39", and between said brackets andr arms are spiral springs 40 which normally force the arms toward each other or into locking engagement with the king bolt. The car body is thus normally held in xed position with respect to its truck. For releasing the said brake arms 35, their ends 137 are provided with links 41, 4l which extend upward toward each other, after the manner of togglelevers, and are connected to the end of a lever 42 pivoted upon the forward end of the car truck platform, as at 43 and longitudinally of the same. The extremeV forward end of this lever 42 reaches down over the edge of theY truck platform and is provided with a friction wheel 44, so that when engaged by the track or a portion thereof the forward end of the lever will be raised, its rear end depressed and the toggle lever links 41 extended to force the gripping arms 35 `apart to release the king bolt. Preferably tripping strips 45 are arranged upon the track after the manner of the friction boards 2'4 to engage the said friction roller 44 of the lever 42 at proper times and elevate the same. lie in the' middle of the track, between the two rows of friction boards, and obviously their length and disposition relative to the said friction boards is such as to disengage the brake means simultaneously with the engagement of the rotating means and to release the brake means as the rollers leave the friction boards.

It will be noted that the car body 12 during its rotation is steadied and held against lateral displacement by rollers 46 horizontally disposed upon vertical posts 47 on the truck 13 and which rollers bear against the sides` of the car body. A very strong' and safe construction of the car is thus obtained,

so that its different movements may all takev place without risk or danger.
