TROLLEY AMUSEMENT.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed January 17,1906. $erial No- 296.496.

i is a specification.

My invention relates to an improvement in trolley amusement devices, having for its object the production of an interesting and sensational ride which passengers may take for recreation in parks, at exhibitions or fairs, on outing trips, and elsewhere.

The leading idea of the .invention is to thrill those who ride with exciting and unusual experiences, due to the rapid flight of a freely moving car down along a spiral course, the car being lifted from the starting point to the top of the spiral prior to the descent, and after said descent it automatically returns to the starting point.

The invention consists essentially in a spiral track, a suitable structure for supporting it, and various appurtenances and adjunctive mechanisms, whereby the general effect and. purpose of the apparatus is attained; and the invention furthermore consists in the construction, arrangement and combination of parts, substantially as will be hereinafter described and claimed.

In the accompanying drawing illustrating my invention: Figure 1 is a side elevation of my improved trolley amusement device. Fig. 2 is a top plan view. Fig. 2 shows one of the cable supports of Fi 2. enlarged partial side view of the spiral track and the structure for supporting it. Fig. 4 is an cnl arged sectional detail view of the mechanism whereby the passenger-carrying car is supported on the track.

Fig. 14 is a side view of a brake device for stopping the car at the proper point where it is to be loaded with passengers. Fig. 15 is a detail of one of the clamps. Fig. 16 shows the attachment of the clip to the cable.

Similar numerals of reference designate corresponding parts throughout the differentfigures of the drawing.

1' denotes a central stationary upright column; its lower end rests on a plate 2, see Fig. 3, supported by some suitable foundation 4; the column 1 is constituted of sections secured together at the joints by means of couplings 8, see Fig. 11, each coupling having flanged halves which are firmly secured to the column sections, and are fastened together by bolts 11 passing through openings 9, one end of the bolt being screw-threaded and provided with a nut 12, and the other having a collar formed thereon and provided with an eye. On the upper end of the col umn 1 is a cap 24, preferably like a half of one of the couplings 8. The bottom plate 2 is provided. with sockets to receive brace rods 3, which reach from the column 1 and extend, preferably, in a downward inclined direction to a series of foundations 5, located at convenient distances from the column 1, and sufficiently embedded in the ground to give a firm anchorage. These foundations 5 are provided with sockets to receive the ends of the rods 3 and also with perforated ribs 6 that are engaged by the lower ends of brace rods or cables 7 which lead upwardly and are connected to the eye-bolts 11, see Figs. 3 and 11. Some of the brace rods or cables 7 which extend upwardly from the foundations 5 are attached to the cap 24. There may be as many of these rods 7 as de sired, and obviously as many of'the foundations 5 as may be suitable, as also of the braces 3.

On the central column 1 is a series of clamps 15 having sockets for holding horizontal arms 14 that carry brackets 21 for supporting a spiral track 13. Track 13 descends from near the top of column 1 to near the bottom in a course of gradually increasing diameter, the degree of inclination of the path depending upon circumstances and the speed which it is desired. to impart to the car, it being obvious that the purpose of the. track is to furnish a descending spiral path down which cipal parts of the structure that upholds this track, the latter is disposed symmetrically around it so that it serves as the vertical axis of the spiral, and hence the clamps 15 are caused to rigidly embrace this column 1, as shown in Figs. 9 and 15. Clamp 15 consists of a split ring, which is preferably'ribbed for the sake of strength and is open at the split to a greater or less extent, the two ends being clamped together by means of a bolt 16, which can be tightened up whenever desired, if by chance the clamp should ever work loose at all. Each arm 14 is carried by a socket on clamp 15 and supports at its outer end a vertical bracket 21, which is bolted to the track 13. On the upper end of the bracket 21 is a perforated lug or ear 23 that receives the lower end of a brace rod 18 having on the lower end thereof a nut 20. The upper end of rod 18 is fastened by means of a bolt 19 to a collar 17 which is clamped to the column 1. The braces 18 thus connect with and support the outer ends of the arms 14, and the nut 20 permits the length of this supporting connection to be regulated and adjusted as may be required. These clamp collars 17 which carry the braces 18 are interspersed, at convenient distances, on the column 1 among or between the clamps 15 which carry the horizontal arms 14.

It will be understood that from the outer end of each arm'14 there leads upward oneof the inclined braces 18, and that consequently in the make up of the structure for sustaining the spiral track, there is a multiplicity of rods, braces, arms and other parts, but they are all so related to each other and relatively disposed in such an effective way that they co-operate and strengthen each other and provide a structure without any weak spots, but amply strong to up-hold the track 13 and enable it to have the requisite stiffness'to permit the travel thereover of the succession of grooved wheels with which the cars are provided. Each bracket 21 is preferably ribbed on the vertical side as shown in Fig. 4 for the sake of strength, although I do not wish to be restricted to any particular form thereof. The track rail 13 is a comparatively thin, vertical plate which is attached sidewise to the bracket 21 by bolts 26 along a line between the upper and lower edges so that the upper edge may enter the grooves in the periphery ofthe wheels of the cars, while the lower edge is free and allows wheels or rollers 62 and 72 to play against both sides, and rollers 63 against the bottom edge of the same, said wheels or rollers being suitably carried by the same frames in which the grooved pulleys 53 are journaled. The working edge of the track 13 on which the pulleys roll is stiffened by means of a suitable strip 66 see Fig. 4, which is secured thereto in any suitable manner.

Before describing the'cars and the means whereby they are enabled to roll. on the track, I will explain other parts of the apparatus. The spiral track of which I have just spoken leads downwardly from a considerable height, say 50 or feet or more from the ground, down to a point, say 15 or 20 feet from the ground. It is necessary to provide means for lifting the car to the top of the spiral so that it may be at the proper place to start on its circuitous course. This means consists of aninclined cable 32 leading from a loading station or terminal at 66, which may have any suitable construction and arrangement, upwardly to a point near the top of the column 1, as shown generally in Fig. 1 and in the enlarged detail view of Fig. 7. The stationary inclined cable 32 at the loading station is suitably guided by rollers or pulleys, and connects at 67 with a horizontal track 68 in lieu of which track a cable may be used if desired, and from this track 68 another track or cable 33 leads horizontally, with ups and downs, or undulations, and easy ascents and descents, on supports 36, passing in its course'through a tunnel 34 and connecting finally with the lower end of the track 13. The inclined cable 32 connects with the upper end of the track 13 by a stationary connection or casting 27, which is suitably recessed or bored to allow the end of the cable 32 to pass into it, as shown in Fig. 7. The cable is fastened to the connection 27, preferably by one or more U-bolts 69, or some other securing devices, and the end of the cable'whichemerges from the casting on the other side may be bent around some stationary object or fastened firmly so that the cable 32 cannot be withdrawn from the casting 27. Thus it will be seen that the car wheels which ride upon the cable 32 will pass with ease-therefrom onto the connection 27 and thence to the track 13, the latter being firmly attached to the connection 27 as shown in Fig. 7. The connection 27, see Figs. 7 and 8, is supported by hangers 30 and 31 from depending arms 29 and 28, which project horizontally from the column 1 and are provided with clamping sleeves 29 and 28, which embrace the column and are firmly clamped thereto.

Parallel to the inclined stationary cable 32- is a moving endless cable 43 which, at its up per end, passes around a sheave 44 rotatable on'the column 1, andat the lower end around a sheave 39 in the loading station, on a vertical shaft 41 actuated by a gearing 40, a drivewheel 38 and an electric or other motor 37.

The endless cable 43, just before it reaches the sheave 39 is deflected from an inclined to a horizontal position by means of idler pulleys 70. Contiguous to the upper sheave 44, at one side, is a pair of idlers 45, 45, supported by bracket 48 carried .by a clamp 49 which embraces the column 1, and has its parts firmly secured. together by means of bolts 50, and at the other side of the sheave 44 is another pair of idler pulleys 46, 46 carried by a bracket 47, similarly supported. from the column 1. These idler pulleys serve to support the endless cable 43 and direct it surely around the sheave 44. The object of this endless cable is to carry the cars from the loading station to the top of the spiral track. Hence, the cable is provided at in tervals of a few feet, say twenty or thirty feet, with projecting clips that engage certain parts of the framework of the car in order that the car may be moved upward, said clips being so fixed as to be automatically disengageable from the car at the proper time when the car leaves the cable and is received by the descending spiral.

The cars used in this device may vary widely in their form and structure. They .are designed to carry a convenient number of passengers and ordinarily will consist of a passenger compartment over which is a canopy. One of these cars is indicated in Fig. 5, at 10, where it is seen that there are two roller frames 52, each having two rollers 53, and from said frame the canopy 71. of the car 10 is hung. One of the frames 52 is shown in enlarged detail in Fig. 4. The wheels 53 are grooved so as to roll on the track 13 and on the cables 32 and 33. The frames 52 are shaped in some suitable manner so that they may carry anti-friction rollers to bear against the lower part of the track 13. Re-

ferring to Fig. 4 it will be seen that said frame 52 has a pair of horizontal rollers 62, suitably journaled to bear against one side of the track 13, and a pair of rollers 72 to bear against the opposite side of the track 13, while one or more rollers 63 is journaled to bear against the under edge of track 13, thus friction is diminished and. the easy motion of the frames along the side of the track is promoted. Referring to Fig. 5 it will be seen that the car 10 is moving in the direction indicated by the arrow, and that the rear frame 52 differs slightly in construction from the forward frame, because in practice I find it most convenient that the clips 60 should engage the rear instead of the forward. frame. Accordingly, the rear frame, or both frames, if desired, is provided with a ledge or surface against which the clip 60 bears. 58, 58 des ignate two dogs provided with springs 59, said dogs being pivoted to the rear side 61 and being normally held by the springs in a position where their edges come close to each other without ineeting, space enough being left for the shank of the clip 60 to move loosely between the dogs, but not enough to allow the head 60 of clip to be withdrawn therethrough. The clips 60 are shown in de tail in Fig. 16, where it is seen that a clamp 7 3 surrounds the cable 43 and has its ends bolted to the shank of the clip 60 by rivets or bolts 74. Referring to Figs. 4 and 5, it will be seen that when the car 10 is in the proper position, one of the clips 60 will pass into the open space with its shank loosely between the dogs 58, and the head 60" will bear against the forward ledge or partitiqn at the point 76, and while so bearing will carry the frame 52 and the car along with it. The fact that the springs 59 hold the dogs 58 with their edges in close proximity to each other, prevents the clip from being released sidewise from the frame 52. When, however, the car reaches the top of the spiral and comes alongside of the upper sheave 44, the peripheral flanges of said sheave will enter the spaces at both sides of the curved surface 76, as indicated in Fig. 4, and the continued movement of the car will cause the dogs 58 to strike against these flanges on sheave 44 and turn them on their pivots, holding them in the deflected position here shown long enough for the clip 60 to be withdrawn from frame 52. The two frames 52, 52 are swiveled at their lower ends on bolt 57, 57 which are shaped with eyes and engaged by rods 55, 55 that are connected to the canopy 71 of the car. The swiveled connection with the wheel frames is for the purpose of allowing these frames to travel easily around curves, while the loose joint between the bolts 57 and the rods 55 and between the rods 55 and the canopy 71, is to permit of such swinging or centrifugal motion. as may occur during the rapid movement of the car. The two bolts 57 are spaced and held rigidly with relation to each other by means of a horizontal connection 54, shown in Fig. 5. Referring 'to Fig. 4, it will be seen that these bolts 57 pass loosely through perforations in the bottom part of the frame 52 and are screw-threaded at the upper end for the retention of a nut andby these means the frame 52 easily swings on the bolt 57 if the latter is held stationary with relation thereto.

I have already described the method of connecting the upper end of the stationary cable 32 to the top portion of the spiral track 13 by using a connecting casting 27 which receives the cable 32 through a hole therein. and allows the said cable to be firmly aflixed thereto. Inasmuch as the course over which the cars travel consists in part of a cable-way and in part of a track or rail, I find it necessary to provide means at other points in addilower end of the inclined cable 32 at 67, Where it connects with the track 68; also at the other end of the track 68, where it connects with the cable 33. I may say that this connection of the cable with the track may in each case be made in any suitable way, but preferably I shall utilize means similar to that already described at the top of the column 1 in connection with the casting 27. It should here be remarked that a cable and a rail can interchangeably be used for the travel of the car wheels, and although in de scribing and illustrating one specimen of my trolley amusement, I have indicated a rigid rail or track at one place and a flexible cable at another, yet I do not wish to be absolutely restricted thereto, but desire the liberty of employing either a cable or a rail in any part I of the circuitous path along which the car travels, and hence the matter of connecting the cable portions with the rail portions of this course is one which is susceptible of the use of a very wide variety of means.

The tunnel 34 through which the car passes is indicated in Fig. 1 as surrounding a portion of the cable 33 which leads from the lower end of the spiral back to the loading station and which carries the car back over it, after it has made the spiral descent, to the point where the passengers are unloaded from the car and a new lot admitted. This tunnel will prove to be an interesting feature in. a ride made up of extraordinary and sensational experiences. Inside of the tunnel I propose to use any suitable scenery 35, or to produce such scenic effects as may be best employed to enliven the travelers. Electrical appliances may be made use of for this purpose, and inside at various points in the tunnel may be arranged suitable wiring and incandescent lamps and other devices, together with means for producing cloud and other effects, and these electrical means may be operated automatically by the passing car, suitable circuit closers and openers being utilized. It is unnecessary to illustrate this automatic means herein or to describe the same in detail, as any well known electrical device for accomplishing the same result may be made use of.

The wheels 53 may, if desired, be provided with ratchets 64 engaged by pawls 65, which latter are pivoted. to the frames 52 in such a position that they may engage the teeth of the ratchet. These ratchets prevent reverse motion of the Wheels when the car is moving up the inclined cable 32 and serve as safety devices. In Fig. 14 I have represented a brake device consisting of an elongated shoe 77, adapted to be engaged by the wheels 53, belonging to the car. A lever, or several levers, three or more 78, pivoted at 79, below the platform 80 are employed to operate the shoe 77, said levers connecting with the shoe by means of links 81. The spring devices 82, whose tension is regulable, bear against the levers 78 and keep them in the position where the shoe 77 is so located that when the car reaches the limit of its travel toward the loading station, it will be automatically acted upon by the brake. This is one way of arranging the brake, though I do not desire to be restricted thereto. The platform 80 is preferably arranged in connection with the loading station 66, and the levers 78 are conveniently placed so that they may be laid hold of by the attendant at that point. In case the devices are arranged as shown in Fig. 15 and the brake is an automatic one, the attendant will, of course, move one of the levers in the direction of the arrow when he wishes to release the car and allow it to go forward. Manifold other forms of brake may be substituted, if desired.

The operation of the trolley amusement will be fully evident from the foregoing description of the construction and arrangement of the various parts. The car, after being loaded. at the station 66, will be moved by hand until it reaches a point at the beginning of the inclined cable 32, where one of the clips 60 will pass into the rear wheel-carrying frame 52 and come into contact with the curved surface 76 on the front ledge or partition of said frame, and this contact or grasping of the car by the clip will, inasmuch as the cable 43 is an endless moving cable, carry the car upward gradually but surely to the top of the spiral track, where the clip will be automatically disengaged from the car through the contact of the dogs 58 with the sheave 44 and the consequent opening of the dogs. As soon as this release of the car from the lifting clip 60 occurs, the car will begin its descent along the spiral rail or track 13, moving faster or slower, according to the inclination of the rail which will be properly adjusted to attain the end in view, and proceeding to the bottom of the spiral, giving to the passengers a rapid flight and the pleasurable experiences attendant thereon. From the lower end of the spiral track the car will pass to the cable 33 rushing through the tunnel 34 and again reaching the loading station.

Manifold changes in the precise construction and arrangement of the parts may be made, and I do not desire to be confined to the particulars of the embodiment herein exemplified, inasmuch as my ideas are broad, and I desire complete protection thereon and the liberty of so modifying and re-arranging the features and elements of my improvements as may be found necessary in order to secure to me the advantages to be derived from the use of the invention.

At the lower end of the endless cable Which lifts the car I can, if desired, employ means for adjusting the position of the lower sheave so as to tighten the cable. Also any suitable means for making the stationary cable tight and taking up slack may be utilized. In or der to steady the central column and in fact the whole structure guy ropes or cables may be used extending from the top of the column to suitable fastenings at a distance and these will protect the column against lateral strain. Referring again to the casting or connection 27 it will be noted that the upper edge is preferably made rounding or round pointed to Fit more easily into the grooved wheels of the car and it has a thinner edge below simi lar to the lower edge of the track 13 in order to fit the safety rollers of the car. The upper edge of connection 27 is horizontal from a point opposite the column, forward and back for a distance of about double the space between the wheels of the car so that the wheels may be on a level when the clip is being disengaged by the large upper sheave wheel. 14. Beyond this point the upper edge slants rapidly in order to give the car accelerated speed at the start and to cause the rail to run under the cables on the returnside.

Alongside of the track 13 and the sheave 44 I find itconvenient to use sometimes an extra flange or guard rail 22, the object of which is to prevent the sheave from pushing the car wheels outwardly from the column, said rail 22 acting like any ordinary guard rail.

Having thus described. my invention, what I claim as new and desire to secure by Let ters Patent, is
