SAMUEL SINGER M M ATTORNEYS United States Patent 3,140,093 BALL GAME WITH PROJECTOR AND AUTOMATIC BALL SUPPLYING AND BACKING MEANS Samuel Singer, 2133 Judah St., San Francisco, Calif. Filed Nov. 13, 1961, Ser. No. 151,614 9 Claims. (Cl. 273-11) The present invention relates to improvements in an apparatus for playing a game and more particularly to an apparatus for playing simulated pocket billiards or pool game.

Pool is a popular and entertaining game which has been enjoyed by many players. The game is generally played on a fiat playing surface on which balls are provided. The game has many variations, most of which involve knocking a playing ball into a pocket with an aimed cue ball.

The game of the present invention also contains these characteristics, but differs from conventional pool in a number of ways. For example, means other than a cue stick is used to propel the aimed cue balls, and ordinarily a plurality of cue balls are used. Instead of a cue, the present invention preferably utilizes a spring-loaded plunger similar to that used in pin-ball or bagatelle games. In addition, the plunger of this invention is mounted so as to provide an aimed propulsion.

Accordingly, it is seen that popular features of two well known and well liked games are combined into a novel game which is adapted to be embodied in a single apparatus. Other minor variations from the obvious counterparts and additional valuable features will be apparent as the description proceeds.

It is a primary object of this invention to provide an apparatus for playing a game which simulates conventional pool and which also contains mechanical devices that provide a pin-ball type shooter and other mechanical devices designed to render the set-up and motions of the machine automatic.

Another object of the invention is to provide an apparatus of the character described which may be coin operated.

A further object of this invention is to provide an apparatus for playing a game using cue balls and playing balls that separates the two classes of balls after they have been played and holds them at their respective stations until ready for use in another game.

Still another object of the invention is to provide an apparatus for playing a game which places one one ball at a time in shooting position in a player-operated shooter.

A still further object of the invention is to provide a game of the character described in which pool balls are placed in a triangular formation by a mechanical racking procedure at the proper position of the playing surface.

Yet another object of the invention is to program the various mechanical functions of the game to provide automatic sequential operation of the various components.

Further objects and advantages of my invention will be apparent as the specification progresses, and the new and useful features of my apparatus for playing a game will be fully defined in the claims attached hereto.

The game of the invention is played on a table similar to a pool table having a rectangular playing surface, re-

that has a handle at one end which the player pulls back 3,140,093 Patented July 7, 1964 to load the spring and propel the ball on release of the handle. Thus control of the propelling force is within the skill of the player. In addition the shooter is mounted so as to be aimed by the player to control the direction of the cue ball. In this way, the player tries to knock the playing balls into the pockets or accomplish any other type shot that is desirable according to the rules of the game.

The actual game played may vary considerably, and the apparatus is capable of many different games or variations of any particular game. For example, points may be scored simply by knocking playing balls into the holes or pockets, and points may be scored or subtracted by knocking or playing a cue ball into a pocket. In addi tion, dilferent credits can be given for knocking balls into pockets of varying diificulty or credit may be given or required for called bank shots and the like.

The game is particularly suited for coin operation and may be placed in any public place where amusement machines are likely to be played by the general public. The game is also suited for use by one or any number of players competing for high scores, that is, either a high score per se or a competitive high score.

The preferred form of my invention is illustrated in the accompanying drawings forming part of this application, in which:

FIGURE 1 is a plan view of a typical apparatus for playing the game of the invention, with portions broken away to illustrate internal parts;

FIGURE 8, a partial sectional elevation taken in the plane of line 8-8 of FIGURE 7; and

FIGURE 9 is a schematic view illustrating a control system utilized for automatic operation of the apparatus shown in FIGURES 1 through 8.

While I have shown only the preferred forms of my invention, it should be understood that various changes or modifications may be made within the scope of the claims attached hereto without departing from the spirit of the invention.

Referring to the drawings in detail, it is seen that this invention includes a table 11 having a rectangular playing surface 12, whereon a game of pool or similar game may be played. The playing surface 12 is defined by upwardly extending cushions 13 having a resilient edge 14. Holes, or pockets 16 are provided in the playing surface and are recessed in the cushions. Preferably, the pockets are positioned at the corners of the rectangle and midway of its long sides. It can be seen that the table thus described is similar to the geometry of a standard pool table.

A shooter 17 is pivotally mounted at the front end of the table midway of one of the short sides of the rectangle. In actual play, one balls are shot from the shooter at the pool balls. The usual plays of pool may be practiced, such as rebounding a ball olf the cushions into other balls, or the pocket. If all goes well the ball or balls will fall into one of the pockets 16.

7 Below the playing surface and running in communication with the pockets is a pair of inclined troughs 18 CD which also serve as a classifier 19 and as passages through which the balls roll. The troughs, as best seen in FIG- URE 4, are generally U shaped, with the U being constructed to form an upper trough 21 and a lower trough 22, the troughs being separated by shoulders 23 in side walls 24 of troughs 18.

In the embodiment illustrated, the classifier 19 is constructed to classify or separate balls of different diameters. Thus cue balls 26 are of a larger diameter than playing balls 27, and cue balls 26 are held in the upper trough 21 while playing, or pool balls 27 drop down into the lower trough 22.

The classifier therefore has a U-shaped channel having upper walls spaced apart a distance larger than the diameter of the cue balls, and'lower side walls spaced apart a distance smaller than the diameter of the cue balls but larger than the diameter of the playing balls. However, other forms or types of size classifiers could be used without departing from the spirit of the invention. In its broad form, for example, the invention could use balls of the same diameter, but of different weight and utilize a classifier adapted to separate balls of different weights.

Although different types of classifiers could be used, it is an important feature that a classifier is used to provide automatic operation of the apparatus. The classifier illustrated is preferred because of its simple construction and reliability of operation.

As best seen in FIGURE 2, the bottom of upper trough 21 as defined by shoulders 23 is inclined toward the front of the table and leads to a first receiving station 28 where the cue balls are collected under the playing surface of the table near the shooter 17. Similarly the lower trough 22 has a bottom 29 which is inclined toward the back of the table in communication with a second receiving station 31 where the playing balls are collected.

In order to transfer the cue balls from the first receiving station 28 to the shooter in position to be played, there is provided an elevator 32, see FIGURES and 6. The elevator includes an elevator shaft 33 having an opening 34 communicating with the receiving station 28, thereby permitting a cue ball to roll into the elevator shaft. An elevator platform 36 is slidable within the shaft and extends around a solenoid 37. Solenoid 37 is capable of pulling the platform 36 down against the force of a compression spring 38 when actuated by pressure switch 39, see FIGURE 9.

In operation, after a cue ball has been shot, pressure switch 39 is closed allowing solenoid 37 to pull down the platform 36. A cue ball then rolls into the shaft 33 through opening 34, which opens pressure switch 39 by pressure-sensitive means on the platform (not shown), thus closing the circuit that actuates the solenoid. The solenoid then allows the spring 38 to push the platform and ball up to the shooting position, while the sides of the platform close opening 34 and prevent entry of another cue ball.

Journaled at the top of the elevator shaft 33 is a semicircular housing 41 carrying the shooter 17, which is preferably of the spring plunger type. As best seen in FIGURES 1 and 2, the shooter comprises a pin or plunger 42 within a spring 43 and having a handle 44 at one end. The spring and pin are housed in a tube 46 with the assembly arranged so that the spring compresses as the handle 44 is drawn back, and the'spring drives the pin forward within the tube 46 when the handle is released. In this way, the forwardly advancing pin strikes a cue ball in shooting position and propels it out onto the playing surface.

It is seen that the spring-loaded pin or plunger drives the ball according to the compressive force supplied by the player. In addition, the shooter 17 is pivotally mounted, as shown in FIGURE 1, and the player can position the shooter in any position between the positions shown'in phantom. In this way the player supplies the aim as well as the speed imparted to the cue ball.

In the embodiment shown in the drawings, it is seen that cue balls feed into the elevator through opening 34 from two directions at the receiving station 28. To keep the balls from jamming in front of the opening 34, a gate 47 is provided, see FIGURE 6, whereby only one side of the receiving station is open when there are any balls on the other side of opening 34. This is accomplished by a pressure switch 48 which actuates a gate solenoid 49 when no balls are on the switch to cause it to open. The pressure switch is long enough so that it will not actuate the solenoid while there are any balls in any position on the switch side of the gate.

After all of the cue balls have been shot from the shooter, the game is completed. In order to begin another game, the cue balls are returned to their receiving station and the playing balls are racked up. Usually balls remain on the playing surface of the table at the completion of the game, and these balls are first removed and sent through the classifier and to their respective receiving stations.

Removal of the balls is accomplished by pulling the playing surface 12 of the table downward as shown in phantom in FIGURE 2 so that the balls will roll into troughs 18 at the front of the table. The playing surface is pulled down by a solenoid 51 against the force of spring 50 which normally supports the surface in a level position. This clears the playing surface and causes all of the balls to roll into the receiving stations where the cue balls are ready to be fed into the elevator and the playing balls are ready to be conveyed into a racking device. The solenoid is then deactivated, and the spring returns the playing surface to its normal position.

As seen in FIGURES 2, 3 and 4, the playing balls in receiving station 31' are in a position behind the playing surface of the table under an extension 52 of the surface and adjacent to a vertical conveyor 53 mounted within the extension. In operation, the conveyor conveys the pool balls or playing balls 27 from the receiving station to a rack 54 on extension 52.

The conveyor comprises a pair of chains 56 riding on sprockets 57, and having pins 58 extending into conveyorway 59 housed in housing 61 and back plate 62. The chains are driven by motor 63 through one of the sprockets. As the pool balls fall through opening 64 in housing 61, the pins 58 form seats which push the ball up above the playing surface and out through opening 66 into a triangular rack member 67.

The rack is carried on the rear cushion by means of brackets 68, as shown in FIGURE 1. The rear cushion is supported by L-shaped arms 69, see FIGURES 1 and 7. Each arm extends below the playing surface where it is pivotally carried by pin 71 extending from chain 72. A roller 73 extends from the distal end of arm 69, and rides in groove 74 to keep arm 69 in a vertical position at all times.

Chain 72 is driven by motor 76, see FIGURE 8, through a gear reducer 77 and one of the sprockets 78. The chain moves the arm and the cushion and rack attached thereto through a flat ellipse, substantially as defined by arrows 79. In this way the racked balls will be deposited in front of the rear cushion 13 in playing position, as shown in phantom in FIGURE 1.

As best seen in FIGURES 3 and 4, the second receiving station 31 that receives the playing balls as they leave the playing surface of the table is adjacent to the conveyor 53 with the balls going from the station to the conveyor through hole 81. As shown in the drawing, balls travel toward the hole from opposite directions. In order to keep the balls from interfering with each other, gate 82 is provided to hold the balls on one side whenever balls are present on the other side. The gate is controlled by solenoid 83 which closes the gate when balls are on pressure switch 84, and opens it when no balls are on the switch.

Although both receiving stations have the cue balls and playing balls coming from opposite directions to the elevator and conveyor respectively, it is also possible to classify either or both types of balls into a single channel that directs them through the corresponding receiving station from one direction. In such cases, gates 47 and 82 may be eliminated.

The apparatus is particularly adapted to be coin operated through a control box 86, see FIGURE 9, because the operating parts are electrically activated and are contained in a closed housing 87 below the table, see FIGURE 2. In such a situation, control box 86 preferably will also contain a conventional counter (not shown) to count the number of cue balls played and stop operation when play has run out. Another coin is then required to activate the control box.

Referring particularly to FIGURE 9, it is seen that the control box 86 activates the various solenoids. As the game is started, the playing surface is first tilted by activation of solenoid 51 which is on for a timed period. At the end of the period, spring 50 returns the playing surface to its normal position, and the timer then provides current to line 88. Activation of line 88 causes the motor 63 to drive the conveyor 53 and operate gate 82 and gate solenoid 83 so that all of the playing balls are delivered to the rack.

As the balls are delivered to the rack, they tend to roll toward the front of the rack until the front is filled. Then the balls are directed to the side corners by a raised portion at 89 on the extension of the table. In this way, the entire rack is filled. As each ball finds its place, it comes to rest over a pressure switch 91, see FIGURES 2 and 9. When all of the switches 91 are closed, motor 76 is activated and it begins to drive the rack forward. As the rack goes forward, switches 91 open, but switch 92 closes to keep the motor 76 energized. Switch 92 is held open, by rear cushion 13 when the cushion is in normal position, but as the cushion is moved forward along with the rack, the switch closes and keeps motor 76 operating until the cushion and rack move through their elliptical path shown by arrows 79 and the cushion is brought back down on switch 92. Motor 76 is then shut otf.

After the balls have been racked up, the timer then activates line 93 and deactivates line 88. Line 93 remains activated until a counter within the control box 86 receives a fixed number of impulses through line 94 with each impulse corresponding to action of pressure switch 39. Switch 39 opens each time a cue ball is shot so it is seen that one complete game is controlled automatically with the control box being shut off on completion of the programmed number of shots.

In the embodiment shown, ten playing balls are used along with ten cue balls. However, other numbers of balls and other modifications of the game may be made as desired, and still provide a game having a high amusement value with automatic operation of the moving parts.
