The object of this invention is to provide means for indicating when a player commits what is termeda technical foul in the game of bowling, by allowing his or her 6 foot to extend, over and beyond the foul line while any portion of the ,foot rests on the alleyway. Various devices have been designed for accomplishing this result, but they have been found impracticable {or use,

because they are not dependable" and freuently are actuated by the ball which is t rown by the player instead of being operated by the foot, My invention overcomes these objections and provides a simple, in-

expensive and effective device .for accomplishing the desired results.

In the accompanying drawing forming part of this specification, Figure 1. is a plan of a detail of a bowling alley near the players and; Fig. 2 is a section'of a detail taken upon the line X X ofFigure 1; Fig. 3isasection of a detailltaken upon the line Y-Y of Figure 2, and Figure: 4, is a diagram illustrating the electric circuit 'employed. I f p g It is customaryfto employ a foul line near the players end of a bowling alley, and according to the rules and regulations adopted by=players, to penalize, a player, whosteps over said line when throwing a ball, and when an portion of the; foot rests uponthe alley. y invention provides a device, which is placed in the floor of the alley and runwayson the foulline- ,or in proximity thereto, but which is made to operate .so as to indicate automaticallyfbya signal when a player encroachesfu'pon the line sufficiently to become penalized. An ob'ection in the use of .contactdevices',]is that t eball when thrown frequentl comes into contact with the foul line, an operates the indicater when not desired. To overcome this objection, I provide a plurality'iof contact points or spots, contact with oneVof-which 45 is insuflicient to operate thesignal, it becomingnecessary to depresstwo or more of the points in order to cfi'ectthe signal. These points are placed near enough together. so that the foot will operate them, but owing to the curvature of the periphery of the bowling ball, it is impossible for the ball to actuate more than one of the ints at a time, which will not cause the signal to operate.

posed in alinement with the foul'line. strip D can be of suitable color, so as to the foul line and each of the of the strip 1 the ball is which i is sli that various designs embodying the principles employed can be used. A' ind1cate's a plate, which is mortised into and across the surface of the floor, dividin the alley way proper B from the runwa C said plate being set with its surface ush with the surface of said floor to which it is secured by means of the screws 2 or-other suitable means. This plate is formed with a channel '3, extending longitudinal] thereof, in which a strip 'D'made'of rub r, composition, wood or other suitable material is placed, having a series of openings 4 dis- The mark plainly openings 4 s designed to receive the head end of a bushin 5 made'of metal or other suitable materi containing a push piece .in the formof a contact ball 6, the periphery of which pro'ects slightly above the surface and 7 containing the ball. The bushing is form with a seat 7 in its upperend against which grossed firmly by a plunger 8, ably supported to move vertically the passage 9 within the bushing, said plunger being urged upwardly by a spring switch arm 10, which'is formed with a curved end 11, pressing upwardly against a convex surface 12 on t plunger. The body of the switch arm 10 s secured firmly to the body of the plate A, which is set in the mortise groove 3'. The bushing 5 is provided with a circular shoulder 13 seated in the body of the plate A, over which the strip D is positioned to clamp the'bushing firml down in place in the body of the plate. e several contact devices, such as described are of similar construction, and are positioned in a row with the balls 6 upon the foul line. The position in which these contact devices are laced can be varied, and it is not essentia that they be in exact alinement, "it being obvious that they can be staggered or arranged in the end of the Ibushin e lower end of the 'be connected by wiring in any any manner desired, so long as the contact devices are made so that it requires the operation of two or more to efiect the o e r+ ation of the signal, which is employe in conjunction therewith. It will be apparent, that should a layer step'on'any of e contact devices, e alls 6 are depressed, causing the switch arms 10 to be moved downwardly within the groove 14 in the plate A. The corresponding groove 25 below plate A in floor C is designed to contain a pair of bus- bars 15 and 16 acting as conductors for electric current, which is employed from a suitable source such as a batte 17 for o rsting a visual signal 18. T ese busars are so arated by a strip of insulating material 1 said bars being fastened together as a unit by means to be hereinafter described. In the construction shown the switch arms 10- are electrically connected through plate A when the latter is made out of metal. When said plate is made out of insulating material the switch arms 10 can well known manner or through the metallic parts of the mechanism.

Below the free end of each switch arm 10, the head of a contactbolt 20 is spaced, whereby when the balls '6 are depressed the switch arms are forced into connection with the heads of the bolts 20 for the purpose of clos' an electric circuit 22 assing throu the bus-bars, signal and attery. The bolts 20 are arranged in series below the ends of the switch arms 10 and every alternate bolt makes connection with one bus-bar while the adjacent bolt or bolts make connection with the other bus-bar, thereby necessitating two switch arms to be dep simultaneousl into connection with the terminal bolts fore the si al is energized. The bolts are turns into threaded engagement with the bus-bars, and the ones which ass through the busbar 15 and enter the ar 16 serve to clamp the bars with the intervening insulatin strip 19 together. The terminal bolts, whic clamp the terminal bars together are insulated from the bar 15 b insulating material 23. The ends of the us-bars are connected to the ends of the circuit 22, such as by binding screws 24;

In operation should the player happen to m on the foul line two or more of the s will be depressed, causing the corresponding switch arms 10 to be pressed into contact with the heads of the terminal bolts, thus closing a circuit through the signal 18 and indicatin that the layer has exceeded the rules of t e game an committed a technical foul. A technical foul is one in which a player encroaches upon the alley wayJ from the run way more than is permitted y the rules of the e. The si aling device is not opera when the wling ball is thrown by the player and rolled over the foul line; The source of electric energy may be in the form of the battery as illustrated or may be derived from any power circuit or suitable source of electrical current. The signal may be of any form desired, the lamp illustrated being one form of visual signal, which can be employed. Any sound producing signal or other suit able signal maybe used when desired. The apparatus may also be modified, and changed in construction, and need not be used with an electrical aptgaratus, the broad principle involved being e employment of a signal actuating device, in whlch it is necessary to actuate more than one actuating device on the foul line before the signal is operated, leaving the bowling ball which is used by the player free to actuate one .of said devices without affecting the signal.

The device can be constructed with the push elements distributed over any distance across the floor formin the 'alle and run ways or the device can be placed wherever desired, either in the alley way proper or run way proper; Its width may also be varied or the device as a whole can be applied to other uses than with bowling alley wa s.

n accordance with the atent statutes I have described the princip es of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the construction shown is onlillustrative and that the invention can carried out by other means and ap lied to uses other than those above set fort within the scope of the following claims:
