Bor C. Jackson, a

I citizen of the United States, residingat Dayvletters and figur l ton, in the of Ohio, have invented certain new and use- Aful "Improvements in Electrical Checker- Boards; and :I dorvdeclare the. following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,.reference being had to. the accompanying drawings, and tothe thereon, which form a. part of thisnspecication. 9

This invention relates -3 is a diagrammatic view of the electrical connections; and Fig. 4 is a perspective view of one of the metallic checkers.

VReferring more particularly to the drawings, the board consists of a face or upper side member 1 upon which the checker spaces are arranged, and the ends of which are provided with pockets 2 formed by depressed portions 3. There is a pocket 2 for each player, and said pockets are adapted 'to be closed by hinged lids 4 for the purpose hereinafter described. The face member 1 is supported on the sides 5 and ends 6 of a box which is provided with a bottom 7, and

n which houses the electrical connections. The

common conductor 12 is provided with a source of electrical energy 13, and an indicator such as a, bell 14. The pins 10 in the nor c. mensen,` for DAYTON, omo.

"154 of which there 'is' one for each. poc et, said rings being attached on the ends of exihle connections 16. The flexible connectrons 16ers connected with the commonconductor12, byconductors 17. In the con- `ductors 17 are switches 18 adapted tothe" closed by Apins 19 mounted in the depressed portions 3. The pins 19. are adapted to be -depressed by the hinged lids 4 when said pockets 2 are adapted to be engaged by Y' al lids are lowered. The rings 15 are adapted v-' to be placed over one of the pins 10 and the flexible connections 16 are adapted to be extended or laced through said pins. This permits the lid to be lowered thereby closing the r ecjtive switch 18, as will be seen from* the rig t ofeach of Figs. l and 3. The circuits are closed on the

checker spaces

8 and 9 by metallic checkers 20 shown in Fig. 4. The metallic checkers bridge the two

members

8 and 9 of the checker spaces when placed thereon.

The operatmn of playing the game is briefly as follows: Assuming that the player at the rlght end of the board anticipates that the player at the left will move one of."

his checkers on the lower right

hand checker space

8 and 9, he thereupon connects his ring 15 with the pin 10 corresponding with that checker space as is shown diagrammatically in Fig. 3. He then laces the connection16 throughthe pins 10 and lowers the lid 4.- The lowering of the lid 4 closes the respective switch 18 and prevents his changing the selection after once made. When the lid 4 is elevated, it hides the pins 10 from the view of the other player, vconsequently it is `not known to one player what move the other player anticipates. If the left player should then move one o his checkers on said space, the electrical circuit will be completed through ductor 17, switch 18, flexible connection 16, ring 15, pin 10, individual conductor 11, checker'space portion 9, checker 20, portion 8, common conductor 12 tothebattery 13. A bell 14 will therefore be sounded. It is contemplated by the rules that a move an-v ticipated by one player and indicated by the bell 14, shall not player.

I claim, l

1. In a device of thel type specified; a checker board consisting of checker spaces forming the terminals of individual split circuits and each of which consists of two be made by the other,

the battery 13, bell 14, right cons checker s ace, electrically connected to one portiono each respective checker space; a common conductor connecting all the other portions of said checker spaces, electrical connections connected to .said common conductor and adapted to be connected with said contact points, thereby completing a circuit, and an'energizer, and an indicator in said circuit.

2. In a. device of the type specified; a checker board consistmg of checker spaces each of whichconsists of two portions adapted to be electrically bridged, a checker adapted to electrically bridge said spaces,

, two contact points for each checker space electrically connected to one portion of their respective checker spaces; a a common con-y ductor connecting all the other portions of said checker spaces; iiexibl'e electrical connections connected to said common conductor and adapted to be connected with said contact points, therebycompleting a circuit; a switch in each flexible electrical connection; and an energizer and an indicator in said circuit.

3. In a device of the type specified; a

checker board provided'with checker spaces each of which consists of two electrically conduct-ing portions, a checker constructed of conducting material and adapted to electrically connect said spaces, a `right and a left contact point for each checker space electrically connected to one portion of their respective checker spaces; a common conductor connect-ing all of the other portions of said checker spaces; fiexible electrical connections connected to said common conductor and adapted to be connected with said contact points, thereby completing a circuit; a switch in each flexible connection; means controlling access to said contact points and also controlling said switches; and an .energizer and an indicatorin said circuit 4. In adevice of the character specified, a ser-ies ofy checker spaces each consisting of two separate portions of conducting material, two oppositely arranged series of contact points electrically conducted to one side of each checker space, a common conductor electrically connected to'the other side of each checker space, said common conductor being also electrically connected with two circuit closing and opening devices, two iexible conductors connected with said circuit opening and closing devices and having contact members adapted to be electrically connected Wtit-hone of the contact points of their respective series, shutters adapted to conceal the hand while selecting the particular contact point for connection with the common circuit through one or the other of said flexible conductors, said shutter being adapted to close one or the other of said circuit closing and opening devices after such selection is made, 'and means such as a checker constructed of conducting material and adapted to be placed on any of said checker spaces to complete the circuit therethrough, and an indicator arranged in the common circuit.

In testimony whereof I aiiix my signature,'in presence of two witnesses.
