Application March 22, 1950, Serial No. 151,292

19 Claims. ((31.273-126) 7 pendent arm suspended from a setting pivot cooperable with the armature of an associated relay to be locked in pendent or set condition, and released by energization of the associated relay to elevate the pin in response to a scoring action in the appurtenant game.

Another object is the provision of a setting and releasing mechanism for use with game targets, or score-indicating objects in the type of game which includes game-operated switches and electrical scoring mechanism actuated or controlled thereby, said setting and releasing mechanism comprising a relay adapted to be operated by an associated one of said switches, score and control switch means operated by the relay armature movements, a pivoted target carrier spring-driven to turn the target, for instance a bowling pin, into raised position to indicate a hit; and a latch to hold the target carrier down in a set condition by a normal condition of the relay armature.

Another object is the provision of an electromagnetic gang reset mechanism for all target or pin carriers.

Yet another object is the provision of a set of simulated bowling pins and electromagnetic setting and tripping mechanism therefor, actuated by switches operated by a playing piece.

Additional objects and aspects of novelty and utility relate to details of the construction and operation of the embodiment described hereinafter in view of the annexed drawings in which:

Fig. 1 is a fragmentary perspective of a bowling game incorporating the invention;

Fig. 2 is a top plan view of the ten-pin setting and tripping unit;

Fig. 3 is a vertical sectional detail along lines 3-3 of Fig. 2 showing one of the pin-setting and tripping relays to enlarged scale;

Fig. 5 is a vertical sectional detail, to enlarged scale, of the pin latching means in set condition, and is taken along lines 5-5 of Fig. 4;

Fig. 6 is a detail like that of Fig. 5 but showing the pin and latching means in tripped or released condition;

Fig. 7 is a perspective detail of the pin latch;

Fig. 8 is a circuit diagram.

Referring to Fig. l, a game utilizing the invention is shown to include a playing surface 12, a backbox or score panel 13, and a pin hood 14.

A playing piece or puck 11 is glided along the surface 12 to score hits on score switches, the operating arms 15 of which are situated in surface 12 beneath corresponding simulated ten pins 16.

ice.

Preferably, a curved, transparent plastic window :17 on said hood shields, said pins, and interior lighting means (not shown) is provided within the hood 14. The lower margin of said shield 17 is raised above the playing surface 12 to permit the puck to pass therebeneath.

The player seeks to hit as many score switch arms 15 as possible by skillful gliding of the puck 11; and, as a result of hits on the score switches, corresponding pins 16 are tripped or released by electromagnetic relay means to cause said pins to be pivoted from the normally lowered or set condition of Fig. l to the hit or elevated condition indicated by the dotted-line representation of pin arm 16A in Fig. 3, such scoring being indicated by illumination of lamps (not shown) behind appropriate score indicia on score panel 13A.

As seen in Figs. 3 and 4, each pin 16 is attached to a rod 16A, which, as in Fig. 5, is secured as at 16B to a channel-shaped pivot bracket 18 (Fig. 6 also) pivoted on pin 19, seated in lugs 20 (Figs. 3 and 4) of relay bracket 21. There are a plurality of said relay brackets 21 mounted on the unit plate 22, as in Fig. 2.

A channel-shaped setting bracket 24, such as shown in Fig. 7, is also mounted on each pivot pin 19 (Figs. 4 and 5) and contains within its channel the pivot bracket 18.

Spring means 25 (Figs. 4, 5, and 6) is attached as at 25A to the pin rod 16A, and anchored as at 25B to the corresponding setting bracket 24 in each pin assembly, and tends to yieldingly couple each pivot bracket and associated pin rod to the setting bracket 24.

As seen particularly in Fig. 4, a torsion spring 26 on' In the normally set or pendent condition of the pin rods 16A, as depicted in Figs. 3, 4, .and 5, each pin'rod is aligned or spotted by a stop arm 27 depending from the unit base plate 22; and the yieldable spring coupling means 25 absorbs the shock of the resetting movement of each pin rod upon being forced (by means to be described) into pendent or set condition.

Associated with each tenpin is an electromagnetic trip} ping or releasing means in the preferred form of a relay such as shown in Fig. 3, and which includes a coil 31) on bracket 21 a pivoted armature 31 to be attracted'by the coil against the eflort of its spring 32,'which spring in the condition of Figs. 3 and 5 tends to lodge the latch ing end or formation 31A in a latching notch 24X in the settingbracket 24 of the associated pin when the latter is in pendent or set ticular advantage in Fig. 5.

When any of the relay coils 30 is energized, the corresponding armature 31 is attracted toward the left as shown in dotted lines in Fig. 3, to withdraw latch end 31A from notch 24X, thereby freeing the setting bracket 24 for movement by its torsion spring 26 to elevate the associated rod 16A and its bowling pin 16. V

In Fig. 3, it will be observed that armature 31 has an oifset 31B, to whichis attached an insulating wafer 33, as at 33A, (see also Fig. 4), which wafer is slotted to receive switch blades 34 to flex the latter downwardly' for circuit-closing engagement with companion switch blades 35 when the coil 30 is energized to attract arma ture 31.

Contacts 3435 are adapted to'be'con'n'ected 'inthe score-control circuits (not shown) for thegame.

Also associated with certain of said relays (Figs. 3

and 4) are switches 38 including downwardly projecting flexible contact blades 39, the lower ends of. .each

of which are positioned in the path of eccentrically sitl atented Nov. 1, 1955- condition, as shown to paruated switch pins 40 (see detail of Fig. seated in pin holes 40A of the corresponding setting bracket (Fig. 7), said holes 40A being eccentric of the holes 19A for pivot pin 19.

Whenever any relay coil 30 is energized to release a set pin, the resulting clockwise turning of the corresponding setting bracket 24, as in Fig. 3, angularly displaces the switch pin 40 from the normally set position of Figs. 3 and 5, to the tripped position of Fig. 6, and away from a normal engagement with the lower end of said switch blade 39, to free the latter, for movement out of normal circuit-closing engagement with its companion contact 39B.

Switches 38 are normally closed when the associated ten pins are pendent or set, and are adapted to be connected in supervisory circuits (not shown) for the associated pins and scoring circuits, and acocrdingly, these switches 38 are referred to as supervisory switches.

The relay contacts 3435 are normally open when the corresponding bowling pins are set or down, whereas at this time the corresponding supervisory switches 38 are closed; and this condition of the switches is reversed when said pins are tripped up.

Means for gang resetting all tripped pins simultaneously, includes an elongated reset bar 50 (Fig. 3) slidably sealed in slots 51 (Fig. 4) in relay brackets 21.

Each reset bar 50 has an elongated slot 50A (Figs. 5 and 6) into which projects one of the end portions 40X (Fig. 4) of the eccentric resetting pin 40, which is also the operator for the supervisory switch.

In Fig. 2 it will appear that each of the four reset bars 50 there shown is common to several relay and pin setting units.

Means for actuating all resetting rods 56 simultaneously in a gang, includes (Fig. 2) a common link rod 54 engaged in the inner end portions of the several reset bars, and spring means 55 urging said link rod, and hence all reset bars 50, forward to a normal position, which corresponds for bars 50 to that illustrated in Fig. 6.

The resetting means further includes a rocker shaft 56 seated in journals 57 and provided with bell crank levers 58 and 59, the former of which engages the link rod 54, and the latter of which levers is linked to the plunger 60 of a resetting solenoid 61.

In the operation of the resetting means, it may be assumed that one or more bowling pins 16 have been hit and elevated, in which condition the associated resetting brackets 24 would be displaced by clockwise rotation from the set position of Fig. 5 to the tripped position of Fig. 6; and it will be observed that in this transition the resetting pin means 40--40X will move from one (left) side of the reset slot 50A toward the opposite (right) side of this slot.

When, as a result of certain control-circuit operations (not illustrated) the resetting solenoid 61 is energized, plunger 60 is attracted from its normal position of Fig. 2 to rock the shaft 56 through crank lever 59, and hence to retract the link bar 54 and shift all reset bars 50 (to ward the left as viewed in Fig. 6) thereby causing the righthand margins of the several reset slots 50A to engage any tripped resetting pin means 4040X and shift the same back toward set condition, that is to say, from the condition of Fig. 6 back to the condition of Fig. 5.

Such shifting of the reset bars 50 causes any trippedout reset brackets 24 to be rotated anti-clockwise a sufficient distance to permit the latching means 31A on the relay armatures to engage in their respective latching notches 24X; and one of the purposes of the resilient coupling means 25 for interconnecting the several tenpin rods 16A to their reset brackets, is to allow an overtravel for said brackets 24 when the pin rods 16A are registered against their stop brackets 27, to ensure positive latching engagement of part 31A in notch 24X.

Moreover, the yieldable connection between pin rods and reset brackets permits a latitude of operating displacement and over-travel for the several reset bars 50 to ensure positive resetting of all tripped pins through the gang operation of all bars by a single driving agency such as solenoid 61.

In the circuit shown in Fig. 8, a score switch 15X is associated with each switch-operating arm 15 on the game field 12, and hence with each bowling pin relay unit 162430.

Assuming the pins to be spotted or set, and that a player lodges the puck 11 on arm 15, score switch 15X would thereby be closed to energize the associated relay and tripping coil 30 via conductor 70, in consequence of which the latching and relay armature means 31-3113 would be attracted in the manner heretofore described, tripping the latch means and permitting the pin 16 to be elevated to the hit position.

It will be recalled that normally the supervisory switch 38 has its contacts 39-39B closed by the pin 40 on the pin setting bracket 24.

In the circuit of Fig. 8, the operating circuit for relay winding 30 is shown completed through the normally closed supervisory contacts. Thus, when the operating circuit for any relay coil 30 is closed by a score switch 15X, the said circuit will be automatically broken by opening of switch 38 to prevent further or continued energization of coil 30 by another puck or a puck which remains lodged on switch operating arm 15.

As a further incident to each tripping operation of the pin unit relays, relay contacts 34-65 are closed to establish via conductor 73 a control circuit to a master unit 74, which is operative to control and cycle the operation of the entire game, with respect to scoring, resetting, and conditioning for replay.

After the player has made a permitted number of throws of the puck 11, the control unit 74 is operative to shut off power to the game until the latter is conditioned for further play, as by operation of the usual coin control means (not shown).

In a bowling game, the player will be allowed ten frames of play, that is the pins will generally be set up ten times in each round of operation of the game, and the player will preferably be given two chances in each frame to make a strike, spare, or other score.

The resetting of the pins for each frame and round of play is under control of the master unit 74, which in turn is controlled via conductor 76 in cyclic operation by a puck switch 75 actuated by the puck in a gravitational return to the player after each permitted throw.

In the unit of Fig. 2, there are ten pin-setting relay units corresponding to the ten pins required for a bowling game; and, to avoid confusion, it is noted that there are five additional relays on the base 22 (these being the five situated around the reset shaft and adjoining solenoid 61), which are for circuit control purposes and have no pins 16.

Each resetting operation of the master unit 74 energizes the resetting solenoid 61 via conductor 69, which results in restoring any and all tripped pins to normal set condition.

The foregoing specification, in illustrating the invention as applied to a bowling game and the use of tenpins 16 as target elements, is not limitative of the intended scope of the invention, since a great variety of target devices may be substituted for pins 16 in apparatus other than a bowling game, and the scope of the invention is not intended to be limited by the illustrative embodiment, excepting as may be specifically set forth in the following claims.
