ELECTRIC FIELD GAM E.

SPECIFICATION forming part of Letters Patent No. 737,257, dated August 25, 1903.

' Application filed March 26, 1902. Serial No. 99,990. (No model.)

To aZZ whom it may concern:

Be it known that I, GERARDO MAJNO,geI1tle man, a subject of the King of'Italy, residing at 9 Via S. Andrea, Milan, Italy, have invented new and useful Improvements in Electric Field Games; and I do hereby declare the. following to be a full, clear, and exact de-' scription of the invention, such aswill enable others skilled in the art to which it appertains to make and use the same.

electric field games.

ing a preferably closed shape. Each car is fitted with a seat having the form of an ani-..

mal, preferably .a horse, and the person mounted on the back of the horse is with the aid of the electrical contrivances put at his disposal or worked by the attendants enabled to cause the artificial horse to imitate the movements of a living animal, so as to transform the whole arrangement into a race ground for electric steeplechase.

The invention is shown by the accompany I mal circumstances.

the resistance-coils 23 flows through the fielding drawings, of which Figure 1 is a perspective view of the Whole: arrangements Fig. 2 is a side elevation of a: car with the horse-shaped seat. Fig. 3 is a plan of thecar. Fig. 4 is a detail view of the connectionbetweenthe artificial horse and the post projecting upward from the car. Fig. 5 is a diagrammatic sketch of the electrical contrivances. .7

lis the race-ground, in which as many slots 2 2 2 are provided as there are cars to be run, such slots being traversed bytheposts 1O, connecting each car with the corresponding seat or artificial horse, and-therefore being arranged on a line standing vertically above the geometrical axis of each track. The motion is imparted to the car by means of an electric motor 3, receiving the current from the bar or Wire 4, laid down incorresp'ondence with the geometrical axis of the track 5 5, through abrush 53,,sliding along sai'd'bar or wire 4. The driving wheels 6 receive the motion from the motor through a couple of pulleys 7 9. The return of the current takes place through the rails 5 and the earth, as is usually the case with overhead-trolley railways.- The means by which the different shown at 23.

tained within the body of the horse, the parts located within the post 10, (between the lines 1 to wand y y,) and the parts mounted on .the

car below the line y y. The current entering from 4 proceeds through 11 12 13 14 15 16 1.7 18 to the rheostatic controller, whose contacts are shown at 19 20 21 22, and the resistance-coils, divided into four sections, -are The lever 25 18, fulcrumed at' ,117, is pulled by the spring 24 in the direction l;of the arrow and normally closes the circuit ja't 19, when'all the sections but one of the resistance-coils 23 will be out of circuit and gthe speed will reach its maximum value under normalconditions. :to simulate that the rider, spurring up his :horse, pushes it forward with a violentrush .a stud at 26 must be resorted to in order to Should it be desired close the circuit along 26 27 28 '29, when the whole of the resistance-coils will be short-circuited and the armature of the motor attain a still greater speed than possible under nor- The current on leaving magnet 30-of the seriesrwound motor 3,-then proceeds through the winding o'fits armature, 'and' discharges to earth" through the rails 5.

The: rheostatie controller lever 25' 18 .is

worked'by the rider with the aid of the reins 31, entering the body of the horsethroughits mouth,"turning around the small pulleys. 32 33.34, and connected with an eye at the: :end 25 of the aforesaid lever. It will be Ieasily j understood that by reining up more and more resistance coils are inserted'a'nd the speed correspondingly.reduced, while when left to itself the horse will run at full speedi. e.,

the maximum speed under normal circumstancesthe circuit being closed at contact 19 by means of the lever 25 18, acted upon by tomatically at a given point of the path by causing the lever 1-37 to turn from the position shown in full lines to that shown in dotted lines,when the motor-circuit will be interrupted and the brake-coil circuit closed through 4 11 37 38 36 5.

The direction in which the horse is run may be reversed by means of the bipolar switch 39 i.e., causing the circuit to be closed through the contacts 42 43, instead of through the contacts 40 41, as shown in full lines, Fig. 5. The horse, resting on the saddle 44, Figs. 2 and 4, which allows of a certain degree of lateral oscillation, is mounted on a spindle 45, which is capable of receiving a to-and-fro movement along the axis of the tubular post 10. During the normal running the spindle 45, as well as the horse, are in their undermost position; but they may be raised and brought to their uppermost position (shown in Fig. 2) by means of the rope 46, turning around the guide-pulleys 47 and 48 and winding itself around the pulley 49, which is loosely mounted on the axis of the driving-wheels 6, but may be made fast thereto by means of the electromagnetic clutch 50, Fig. The magnetizing-coil of said clutch is shown at 51, Fig. 5. Its circuit may be either interrupted or closed by means of the switch 52, which is provided with two contacts and turns about ninety degrees on dashing against obstacles at predetermined points of the path. Vhen the circuit of the coil 51, which was formerly interrupted, gets abruptly closed, clutch 50 will at once engage with pulley 49 and the horse will suddenly jump up, simulating the leap over the hedge. ()n the circuit of coil 51 being interrupted again the weight of the horse will return it in its undermost position.

It will be understood that the revolution of the switch 52 upon its axis by the contact of either of its projecting arms with an obstaole on the ground may be utilized in many ways to open or close the shunt-circuit on which the magnetizing-coil 51 is included.

Having now described my invention and the manner in which the same is to be performed, what I claim is 1. An electric game consisting of a raceground with tracks situated below the same on which electrically-driven cars run, such cars carrying posts which go through slots provided for in the raceground and carry horse-shaped seats for the rider who has at his disposal means for controlling the speed by acting on the reins and means within the supports of the seats for giving vertical toand-fro movement to the seats.

2. An electric game consisting of a raceground with tracks situated below the same on which electrically-driven cars run, such cars carrying posts which go through slots provided for in the raceground and carry horse-shaped seats for the rider in combination with an arrangement as hereinbefore described under the control of reins carried by said seat and according to which the horse, when left to itself, runs full speed.

An electric game consisting of a raceground with tracks situated below the same on which electrically-driven cars ,run, such cars carrying posts which go through slots horse-shaped seats for the rider in combination with means as hereinbefore described for obtaining a rush as if the horse had been spurred by his rider.

4. An electric game consisting of a racegro'und with tracks situated below the same on which electrically-driven cars run, such cars carrying posts which go through slots provided for in the race-ground and carry horse-shaped seats for the rider, vertical sliciable supports for said seats, an oscillating connection for each seat on said slidable sup port in combination with means as hereinbefore described for interrupting the circuit of the motor and actuating a brake.

5. An electric game consisting of a raceground with tracks situated below the same on which electrically-driven cars run, such cars carrying posts which go through slots provided for in the race-ground and carry horse-shaped seats for the rider and a vertical slidable spindle and tubular support for each seat to allow vertical to-and-fro movement of the seat in combination with means as hereinbefore described for causing the horse to suddenly jump up simulating the leap over the hedge.

In witness whereof I have hereunto set my hand in presence of two witnesses.
