THOMAS O. DEVLIN, OF PUEBLO, COLORADO.

AUTOMATIC POOL-REGISTER.

SPECIFICATION forming part of Letters Patent No. 409,937, dated August 27, 1889. Application filed January 8, 1889. Serial No. 295,810. (No model.)

To @ZZ whom it may concern'.-

Be it known that I, THOMAS C. DEVLIN, residing at Pueblo, county of Pueblo, and State of Colorado, have invented a new and Improved Automatic Fool-Register, of which the following is a full, clear, and exact description.

A The object of my invention is to provide ar device for automatically registering the number of balls pocketed by each player in the game of pool without the necessity of taking the balls out of the pocket, and the time, trouble, and danger of dropping and breaking them incident to handling the same.

Its object is also to automatically keep a correct tally or count of the game, so that the proprietor may not be imposed upon by the players.

For accomplishing these objects my invention consists in an electrical register of pecuhar construction to be placed against the wall of the pool-room in an elevated position in full view of the players, where each player may observe his own score with that of the others, and with which electrical register there is connected a battery-circuit extending to the pool-table and having a circuit-breaker placed in a trough leading from the pockets of the pool-table, so that each ball as it is pocketed will alternately close and open the circuit and thus effect its own count on the register, as will be hereinafter fully described.

Figure l is a front elevation of the entire apparatus. Fig. 2 is a rear elevation of the lower part of the same, on alarger scale, with parts broken away. Fig. 3 is a vertical section through the line a: 0c of Fig. 2, looking in the direction of the arrow. Fig. 4 is a hori- Zontal section through line y y of Fig. 2. Fig. 5 is a front view of the device shown in Fig. 4, looking in the direction of the arrow; and Fig. 6 is a diagram of the circuits.

In the drawings, Fig. l, A A are two upright hollow columns, mounted upon a base B and connected at the top by a shelf B. Extending in horizontal direction from one column A to the other A', and parallel with each other, are a series of shelves C, which correspond in number to the number of players that may engage in the game. Each one of these series of shelves has a number set opposite to it on column A, (see Fig. 1,) and each shelf has a number of balls O -eight altogether, as shown, or as many as may constitute enough to win the game. These series ot' balls are arranged upon the left-hand side of the shelves and remain stationary.

D are a series of sliding shutters, which slide or roll by means of triction-rollers on metal iianges a at the front edges of the shelves, Figs. 3 and l. These shutters lie directly in front of the balls and obscure the same, but have a range of movement from a position in front of the balls, where they hide the balls, to a position on the right, which exposes the balls. These shutters, by automatic mechanism hereinafter described, are arranged to move to one side and expose one ball on the shelf for each ball that is pocketed by the player. For this purpose the back of each shutter is provided with a rack or toothed bar I), extending from one end to the other. This rack-bar engages a toothed wheel c, Figs. 2, 3, and 4, turning loosely upon a vertical shaft E,which passes through the middle of each shelf. This wheel has a drum or hub c on its lower side and a ratchet-wheel c2 on its upper side. Around the drum is wound a cord c3, whi' h passes over a fixed pulley c* in the rear, and is attached to a weight c5, which serves to rotate the toothed wheel and slide the shutter away from its position in front of the balls. Instead of this weight and cord a coiled spring' may be located in the drum below the wheel. This toothed wheel is held against rotation by a horizontal detent d, Fig. 4, which is pivoted to an upright bar F in rear of the register and which detent is held bya spring d against one of the teeth of the ratchet on the upper surface of the wheel c. This detent is constructed as the armature to a magnet G, and when this magnet attracts the armature the latter is drawn away from the ratchet-wheel for an instant, and the ratchet and toothed wheel, responding to the strain of the weight, rotates one tooth and moves the shutter a sufficient distance to eX- pose one ball.

Each shutter is provided with a set of devices corresponding to those just described, and each magnet for each shutter (see Figs. l and G) has one wire ealeading to a switclb board H and connecting with a separate inn IOO sulated contact-plate e c2 e c4 c5 e6 e7 e8, arranged thereon in circular series. The othel` wires of the magnet lead to the automatic` battery extends to a central shaft J of the switch-board, and is electrically connected to the swinging key or crank K, whose platinumv face may be turned upon any one of the contact-plates e to e8.

T is a section of the trough which carries the balls from the pocket-s of the pool-table to f any suitable receptacle to receive them. In the bottom of this trough is a hinged section t, held up by a spring t. This sectiont is electrically connected to one circuit-wire g, and a bracket t2 is connected to the other circuit-wire g. lVhenever one of the balls pocketed by a player runs down the trough, it for an instant depresses section t and closes contact between it and bracket t2, thus transmitting an electrical impulse through any one of the magnets, according to the position of the lever K on the switch-board. When the switch-lever is on plate e', the magnet No. l is in circuit for automatic action from the passage of the balls in the trough, and magnet No. l registers the score of the first player by exposing the saine number of balls in the first row there are balls made by this player. When the next player takes his turn, the key-lever is swung over to the next plate of the switch-board and the circuit is thereby established through the magnet No. 2 for the second row of balls, and so on.

After the game has been played the shutters are slid back again over the balls preparatory to commencing a new game. To do this a vertical bar L, Figs. 5 and et, is arranged in front of the shelves and in the same plane with the shutters, and this bar is made to travel from right to left and to strike against the ends of all of the shutters and force them simultaneously back over the balls, so asto hide them from view. To accomplish this the vertical bar L is attached to a horizontal bar L', that slides in a groove t' in the middle shelf. These bars are drawn to the right by a cordj, Figs. l and 2, which passes'over a pulley j and is attached to a weight, and are drawn to the left by a cord 7c, Figs. 4 and l, which passes around a grooved pulley M, journaled in the hollow left-hand column A of the register. One turn of this pulley takes upsuflioient of the cord to close all the shutters, which is effected by a crank-handle N, attached to the pulley-shaft. On this shaft, just inrear of the pulley, is a tappet-arm Z, Fig. 2, which as the pulley is rotated strikes a lug m on avertical sliding bar n. This bar is normally Iheld down by a spiral spring o, and its upper end carries a tooth p, that when raised engages a tooth on aratchet-wheel q and turns this ratchet-wheel one notch. This ratchet-wheel is fast on a shaft which extends through the casing and carries anindex-hand r, Fig. 1, that traverses a dial s and at each movement registers for the benefit of the proprietor the game that has just been played. After the game has been played then a single turn of the crank-handle N serves to effect the resetting of the shutters in front of the balls, and the tappet-arm Z on the crankshaft also lifts the lug m on the sliding vertical bar n, and this by turning the ratchetwheel above moves the index-hand and reg-4 isters the game. Froni this construction and arrangement of parts it will be seen that 1t 1s impossible at the close of one game to go to 'the next without first registering the game,

so that the proprietor of the table cannot be imposed upon by the reporting of a smaller number of games than have been played.

In the construction of the case of the register the space at P. between the columns A A and the shelves and base B is utilized for the batteries that are employed. The right-hand portion of the shelves into which the shutters slide is covered bya screen constructed as a blackboard R for memoranda or independent counting. The players switches are at the right-hand upper corner. The proprietors register is at the left-hand upper corner, both being surmounted by vases or suitable ornaments, while a mirrorR is arranged between, thus making a very useful and or namental piece of furniture, in which the count is surely and automa-ticallyeifected without fraud, without danger of dropping and breaking the balls, and without prejudice to the interests of the proprietor.

I prefer to use on the shelves balls of the same size and appearance as the pool-balls as counters; but painted gures, blocks, or

IOO

other counters may be substituted for said balls on the shelves.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

1. An automatic pool-register consisting of an electric circuit and attery, an inclined trough or way for the balls having a movable plate orbar in the same for making and break- 4ing said circuit by the passage of the balls, a

series of counters for the different players, an electro-magnetic adjusting device for the counter, and an electric switch for throwing the circuit through any one of the electromagnetic adjusting devices, substantially as described.

2. In a pool-register, the combination, with a series of shelves, of a series of balls or counters arranged thereon, a series of shutters arranged in front of the same, and adj usting devices for removing the shutters from their position in front of the ball, consisting of a rack-bar on the back of the shutter, a toothed wheel engaging the same and provided with a ratchetand a hub, a cord and pulley actuating the hub, and an electro-inagnet and detent-armature engaging the ratchet, as described.
