SAFETY DEVICE'FOB ROLLER COASTERS.

Application filed may 26,

v To all whom it may concern:

State of New York, have invented certain new and useful Improvements in. Safety Devices for Roller Coasters, of which the fol lowing is specification.

The invention relates to safety devices for roller coasters in which a series of cars power up a main inclined section of an end less track from which point they are adapted to run by gravity over track sections comprising a plurality of down grades, dips and risers. i

The general object of the present invention is to provide means by which the movement of the cars or trains running bygravity under separated headway may be automatically controlled or intercepted to avoid collisions.

More particularly the invention has for an object the provision of means whereby the accidental backward movement of a car or train on one section of the track will cause the interception of movement of a train on a preceding track section, and will shut off the power and temporarily prevent further advancement of succeeding trains.

The invention also includes certain details of construction and arrangement of parts hereinafter set forth.

For further comprehension of the invention, and of the objects and advantages thereof, reference is had to the following description and accompanying drawings, and to the appended claims in which the various features of the invention are'more particularly pointed out.

As indicated by the drawings the track is arranged in the general form of a loop in aplurality of sections, beginning its lowermost level atthepower receiving point 10, and extending upwardly to form a main. incline or riser 11 to an extreme upper level 12, from which point the track extends in a downward grade to form substantially a horizontally extending curved section 13, continuing in a dip or downward, incline 14., whereit merges into a curved section 15, thence into a riser 16 to the point .17, where itbeginsa second downward slope toform a curved tracksection 18; from which latter point the track continues its. general downward descent by a series of well known dips and rises, not shown, to its; lowermost curved level indicated at 19, thelatter level serving as a receiving and sending section for the cars and an operating station, forg controlling the movements thereof; the friction devices disposed along the track. For elevating the cars; up the incline 11, an endless chain 20 is provided andarranged to run over aseriesofidlers 21, 22, 23, 24

and driven by thechain wheel 25 which in turn is driven. by the :pulley 26,belt from the pulley 28 on the electric motor 29,tlie operating vcurrent for the'latteiq being controlled from the switch handleBl) arranged to be opened, as indicated inv dotted lines, by the lever 31 conveniently mounted adj acent the motoronthe upright 32.

The upper curve track sections 13 are suitably supported on the structureindicated.

at 33,-which also carries the friction plates conveniently spaced with respect to the track and adapted to be. engaged icy correspondingly spaced shoes 73arranged'0n the bottom surface of the cars.- The friction; plates are supported through blocking35 upon the track structure in afyielding manner by bolts, 36, passing. through the structure, and provided with springs 37 and so arranged as tov exert a. downward thrush;

I upon the plates. For operating. the friction plates a series of cam levers 38 are provided and pivoted to the track structure at 39,. the upper or plate engaging ends thereof being cam shapedor eccentrically arranged With respect to their pivot points, while the lower ends of the levers are pivotally connected together in pairs by the connection rods 40; and for operating each of the said pairs of connected cam levers 38, a bellcrank lever 41 is provided,' the latter being pivotally mounted by a vertical pin 42, fixed in the bracket '43, con-w veniently carried by the track structure. A connecting rod 44 connects one end of the bell-crank lever to the jointly connected pair of cam levers While the opposite arms, of

i the bellcrank levers are jointly connected together by the rods 45, as shown in Fig. 1. At one end of the series of bell-crank levers the direction of operating movement is changed from a substantially horizontal path to avertical one by means of a connection rod'46 engaging a bell-crank lever 47, the latter being pivotally mounted on a horizontal axis and adapted by its move ment in opposite directions to jointly operate the series of cam levers 38 in a similar inanner. I

For operating the above friction device as an emergency brake, a Weight 48 is employed and provided at its upper end with an eye rod 49, in Which is'connected a shackle outer end of the bell-crank lever 47 in such manner as to afford a slaclr condition of l1l16 0&blQ While the Weightis supported by the'hook 51. To the free end of the detent arm 55 is secured an operating line 58 which passes over an idler Wheel 59 and is adapted to raise the outer end of the detent arm and thereby release the carrier rod 52, al-' lovving the latter to turn about its pivotal point and drop the Weight 48, theforce of vvhlch acting through the cable 57 and lever 47 serves to raise the yielding friction plates 34 a sufficient amount to afford a full frictional or bra-king engagementupon the 55 ter toa complete stop.

F ixed upon the supporting members '60 shoes of the moving cars andbring the latand 61 ofthe inclined riser section 16, is a safety device adapted to operate through the line 58 to release the Weight and set the emergency brake. As shown in the detail plan v1eW,Eig. 6, and-in the partial sectional elevatloml ig. 7, the safety device comprises a block orcase 62 having an elongated reces's 63 and a slot 64 extending through said er'ativei ha ides? case, the recess being shaped to loosely receive an elongated tongue 65 of variable Width. In its normal position as shown the forward or upper end of the tongue is raised above the upper surface of the case Where it engages as a stop the forward end Wall 66 of the recess, Which engagement is normally maintained by the flexible line 67 passing over the sheave Wheel 68 rotatably mounted the block. 7 At its lower or rearward end the tongue is formed for a distance in a relatively narrow Width which gradually increases to form a shoulder or bend 69 about Which the tongue is adapted to rock as a pivotalpoint, the lower or nan rovv end of the tongue engaging the up Wardly inclined bottom Wall 70 of the re; cess. At its upper end the line (57 is fixed to'the narrow loWer end of the tongue and at its lower end theline is provided With a Weight 71 adapted to exert a force tending to hold the lower or narrow end of the tongue against the inclined Wall 70 and the upper end of the ton; 2;ucagainst the stop Wall 66 and above the upper surface of the case, the latter being provided With a cover plate TQ'arranged to cover a section of the recess and to limit the upward movement of the tongue. During the ordinary run ning movementof the cars over the track,

one of the car-shoes 73 engages the'up Wardly projecting tongue member 65 and downwardly-forces the same about its pivotal point 69 and into the recess, the other parts of the safety device remaining inop- In the normal movement of the cars over the dip section 14 of the track, the velocity obtained therebyis sufficient to carry the carsvvcll over the relatively shorter and flatter riser section 16 and along the descend in grade 18; but in the event of an unforeseen obstruction or disarrangement of any of the parts thereof tending to cause addi tlonal IfIlCtlO-Il resistance to the running movement of'the cars, resulting in the arrest of their forward movement before reaching the top of the riser section and a backward movement thereof, then the rear end of the car-shoe 78 will in their back- Ward movement engage the upper projecting end of the tongue65. In this latter en gagement the tongue will be forced to slide lengthwise along the recess 63 and below the cover plate 72 and against the resistance of the connected Weight 71; the lower or narrow end of the tongue being upwardly forced over the inclined bottom Irv-all '20 and into engagement With the upper end of the lever 74 pivotally mounted in the bracket 75, fixed to the adjacent track-support 6].. In its engagement by the tongue, the upper end of the lever 74 is adapted to move in the slot 64, While its opposite or lower end is connected to the line 58 and serves to ing chain and thus prevent c advancement otthe cars along: the track.

in cars over the ll hile the inoveinen. intercepted by the above-c "encv brake, operating from the riion plates n1 o't said aiso l emei agency station adjacent the levelot This hand lever is formed 7 I e a ranged with inflexible connecleading through aconveniently arrang i ll spondingl shaped leve "friction device. Upon the arm '77 is'lixed a Wear-plate S73 adapted to the gradm ated teeth formed in "the plate 82 hired to the standard "T8, andbv the adjustment of the he plate corresponding adjustments may be made through the connection rods to raise and lower the friction plates relatively to the cars to effect on the latter a variable degree of frictional resistance, and thereby control their rate of movement along the track. Also pivotally carried by the standard 78 is a second hand lever 83 having an arm 8 iconnected to the line 85, leading to an idler or sheave Wheel corresponding to and lateral y position-ed with respect to the idler wheel 59, and froznwhich point the line led and made "fast to the end of the detent arm 05. As thus connected the hand lever 85% may at any time be operated to release the Weight and the emergency 0'5 the line 58. v

In the general running operation of the cars aronn" thetrack with respect to the se ral safety devices, a loaded'train co1n need at the operating or receiving station along the dovrn grade lower level of the l riction plates 3t engaging hand lever 7T,located it and pivotally mounted the outer end of which is verBll to the corre- 1' 4i? connected to the,

The interception or accidental stoppage of a train during its gravity nioveinent up the riser section 16 may be due to various causes, as displace ment of trackor car parts, or ot carelessness or toolery on the part of the passengers.

For the further operative control of the cars, the track maybe provided at' desired terruption of the service, that the detached parts may be speedily replaced intothe normalivorking position withdittle or no "loss of time. H 3
