RACE-TRACK AMUSEM ENT APPARATUS.

SPECIFICATION forming part of Letters Patent No. 726,282, dated April 28, 1903. Application filed July 18, 1902. Serial No- 1 16,033. (No model.)

To all whom it may concern:

Beit known that I, WILLARD H. GILMAN, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain "new and useful Improvements in Race Track Amusement Apparatus, of which the follow- 1ng 1s a specification.

This invention relates to race courses or,

tracks; and it has for its object to provide a course whereby two or more racers starting together may have a series ofhandicaps or impediments imposed in their paths at intervals, the handicapping or non-handicapping of theracer being a matter of uncertainty with him.

The invention consists in certain novel features of construction and arrangement for carrying out the above objects' 'and otherwise improving upon the general structure ofam usement race-tracks, substantially as h ereinafter described and claimed.

Of the accompanying drawings, Figure 1 represents a plan view of an amusement racetrack constructed in accordance with my inventlon. Fig. 2 represents a detail perspec-, t1 ve vlew thereof. Fig. 3 represents a plan v ew of one of the cars. Fig. at represents a side elevation showing a section of one of the tracks and the car thereon. Fig. 5 represents a side elevation showing the manner of restoring the cars from the end or lowest level of the track to the beginning orv highest level.

thereof. Fig. 6 represents a transverse sec- 'tional view of the track with a truck thereendless parallel tracks, four in-number in the present instance, suspended a suitable distance above the ground upon supports which, as here shown, comprise arches having uprights 21 21 and cross-beams 22 22, spanning the series -of tracks, said tracks being supported by brackets 23 23 from the crossbeams. Each trackg20'has one or more trucks 25 mounted upon it and from which is suspended a carriage or car 26 of any suitable form adapted to support one or more riders or passengers. At the bottomof each car is shown a pair of lower trucks 27, having roll;-

ers 28, mounted upon a vertical axis and adapted to bear against a running-board 29, placed at each curve of the courseparallel to the main track 20, on the outer side thereof,

and adapted to counteract the effect of oentrifugal force when the car rounds the curve.

Each truck 25 is provided with running wheels 30, resting on the upper edge of the track 20, and with safety-wheels 31, adapted to cooperate with thellower edge of' the track to prevent derailing of thecar. The track 20 has its beginning or starting=point 32 ele:

vated a suitable distance above its finishingpoint 33, as indicated in Fig. 5, so that the car being put in motion at the starting-point will run by gravity around the track to the finishingpoint. The passengers having been unloaded at the finishing-point, the empty car is then drawn'up an ipcline 34 to the starting-point by means of an endless continuously-ru'nning cable 35, having one ormore projections 36 to engage the truck of the car. The equipment of all of the tracks 20 is alike,,and at suitable intervals at correspond.

ing places on the several tracks I preferably provide a series of inclines 37 with interveniug horizontal portions 38. hen a car comes upon any one of the inclines 37, it will, it uhimpeded, receive an acceleration of speed which carries it along to the next incline. The spaces intervening between the inclines may of course be themselves slightly inclined, if desired, instead of horizontal. -At suitable points, preferably one at each incline 37, I mount suitable projections 39 upon the track, adapted to act as impediments or handicaps if encountered by the car. On each truck is mounted a strong spring 40, whose free end is normally held retracted by means of a catch 41, operated by an electromagnet 42, mounted on the truck. The spring 40 has a projection 43, adapted to have extendedcontact with the projections 39 when the free end of the spring is released from the catch 41, but adapted to have only a slight connection with the projection 3!! when said spring is engagedby its latch. The release of any spring prior to reaching one of the projections 39 will cause said spring to act as a drag against the pro- ,iection by its frictional contact therewith,

and thus impede the progress of the car. In passing against the projection 39 the released spring is reset into engagement with its catch 41.

Means for controlling the action of the electromagnets 42 are provided as follows: On each car 26 is mounted a pivotal contact-arm 44, cooperating with a series of contacts 45 45 and controlled by the passenger of the ear in a suitable manner, preferably by means of a pair of reins 46 46, attached to the ends of a cross-lever 47, connected with the contactarm 4.4. \Vires 1 2 3 4 5 0 and 7 run from the pivot of the contact-arm 44, the several contacts 45, and the terminals of the magnet 42 to a series of contact-brushes 1 2' .3' l 5 G 7', mounted upon the truck 25 and adapted to make contact with a similar number of elongated contacts 1" 2" 3 4 5" 6" 7", mounted upon the track 20. One series of said contacts is placed immediately in advance of each of the projections 39 and is connected by wires 1 2 3 4 5 6 7 witha suitable controllingstation, at which is located a battery or other source of current 49, as seen in Fig. 8, connected with the wires 6 7, and a pair of switches 50 50, connected with the wire 5 and adapted to make contact with any of the wires 1 2 3 4.

The operation is as follows: The cars 26 with the passengers therein are started side by side, at the high starting-point in the series of tracks, and run by gravity around to the finishing-point. All conditions being equal, the cars would supposedly finish at substantially the same time; but by the operation of the handicaps on some or all of the cars in vari-' ous degrees and at different points along the tracks any of the cars may be retarded in a greater-"or less degree. With the electrical arrangements, as in Fig. 8, there are on each car always two active contacts 45, upon which if the arm 44 is placed the spring 40 of the cartruck will be released, and two inactive contacts 45,which produce no effect on the sprin The arrangement of thelive and dead circuits controlled bythe switches 50is unknown to the passenger in the car, and he operates the arm 44 at random, without knowing what effect it will have. In Fig. 8 if the arm 44 should be on tlie first contact current would pass from the battery 49 through wire 6, contact 6", brush 6, wire 6 arm 44, firstcontact 45, wire 4 brush 4, contact 4", wire 4, right-hand switch 50, wire 5, contact 5. brush 5, wire 5 magnet 42, wire 7*, brush 7", contact 7", and wire 7, hack to the battery. The current can be similarly traced for the second contact,so that if the arm 44 is on either the first orsecond contacts the magnet 42 will be energized, releasing the spring 40 and retarding the car, while if said arm is on either the first or;the second contacts no release of the'spring will occur and the car will not be retarded. The arrangement of the switches 50 may, be changed at will or automatically at stated intervals, and it is evident that considerable excitement is provided, owing to the uncertainty of the results of the race between the ears on the several tracks.
