Application July 5, 1956, Serial No. 595,886 8 Claims. (Cl. 273-1022) This invention pertains to a target device, and more particularly to a target device at which balls or similar objects may be projected or thrown and the accuracy of the h t upon the target recorded in -a suitable manner.

It is an object of the invention to provide a target device useful either for actual training purposes, or one which may serve simply for amusement or entertainment. Wh le the basic concept of the invention is applicable to various games of skill involving the striking of a target by an object, it is particularly suitable for providing a baseball pitching target device which indicates the accuracy of the pitcher.

It is accordingly a further object of the invention to provide a device which can be used in simulating the pitching of a baseball from a pitchers box to home plate on a regulation baseball field, and to record temporarily for the player the result of his pitch in order to give him a visual indication of how accurate the pitch was.

In brief, a preferred embodiment of a device constructed in accordance with the invention comprises a tiltable target member or drum suitably supported upon a base or standard. The drum is positioned at a predetermined distance from the thrower or pitcher, with an end facing the latter, and it is the object of the game to throw a baseball at, and to strike the center of, the target marking or bullseye on the face of the drum. Depending upon the accuracy with which the thrower strikes the target; that is, the nearness to the bullseye with which he strikes the drum, the latter is caused to tip or tilt about a central axis or about rectangularly related central axes. The amount of rotational displacement about an axis is inversely proportional to the accuracy of the throw, that is, the less accurate the throw, the more the target tilts. In order to provide a recording of the result of each throw, the device includes an indicator system, comprising tell-lights which register in accordance with the amount of tilt of the device. Manual means for extinguishing the lights is provided so that after each throw and recording or noting of the score obtained, the indicator system may be cleared for recording the result of the next throw.

A game device constructed in accordance with the present invention is characterized by relatively simple mechanical construction, but at the same time affords excellent accuracy in recording the results of the hit upon the target. The device is exceptionally rugged and little or no adjustment of it is required once it has been properly set up. With all this, the device is one which can be constructed at low cost, yet provides excellent operation and real enjoyment for persons using it. It is easily adapted for use indoors or outdoors and while having great appeal as an amusement device, as mentioned previously, it may also be used with good effect as a training device for baseball pitching practice. Thus the device may be so set up at the regulation distance from the pitcher, and may be positioned at such a level, as to compel a player to pitch a ball in much the same manner as that actually required of a pitcher in attempting to get the ball across home plate and within the strike zone in a regular game.

'Various other objects of the invention will become apparent from the following description and accompanying drawings in which certain modes of carrying out the present invention are described and shown for illustrative purposes.

Figs. 13, 14, 15 and 16 are sectional views on lines 1313, 14-14, 1515, and 1616 respectively, in Fig. 12; and

Fig. 17 is a schematic diagram of the electrical circuit for the indicator system employed in connection with the target device shown in Figs. 9 through 12.

A relatively simple form of the game device constructed in accordance with the present invention adapted for use as a baseballtarget, is illustrated in Figs. 1 and 2 of the drawings. As there seen, the device comprises a drum 20 having a central axle or rock shaft 22 which is supported horizontally in a simple frame structure 24. The latter is composed of suitable piping 26 and an adjustable cross brace 28 forming a pair of A-frames. Each of these frames is mounted on a wooden base 30, and each leg of the frames is joined to the respectively opposite leg of the other by a tie 32. Suitable pillow blocks or bearings 34 are secured to the top member 35 of each A-frame, and rock shaft 22 is rotatably carried in these hearings at either side of drum 204. Thus the drum may be freely tipped or tilted about its central horizontal axis. In order to make the drum normally assume a position in which its end faces are substantially vertical, a counter-weight 36 is secured as shown to one side of the drum.

The face of the target drum is covered by a suitably stretched flexible membrane 38 on which is centrally painted a bullseye 40. A soft rubber ring 41 covers the rim of the drum to prevent damage to it if struck by a ball, as well as to prevent cutting of the ball. Similar protection to other exposed parts of the device, including the frame structure, is preferably employed. A pitcher, standing at a suitable distance from the target device, throws a baseball at the target, attempting to hit the bullseye 40. on the line of rock shaft 22, there will of course be little or no rocking or tilting of the target drum; however, if the ball strikes the target at some point above or below this axis, the drum will tilt or rock accordingly.

along The amount of tipping will be proportional to the dis- If the ball strikes the target substantially tarrce from the axis at which the ball strikes the target. Therefore in order to provide 'an indication of the accuracy of the throw, the game device incorporates indicator means 42, as seen in Fig. 1, which registers ascore in accordance with the amount -of tipping "of the drum about its horizontal axis.

'The indicator-device '42 comprises a set of four panels 44 whichare translucent and bear scoring indicia thereon. In the present instance such scoring indicia comprises the numerals 4," 3, '2, and 'l. Cubicles located behind each of these panels each contain an electric light which illuminates its respective panel to indicate a score and the illumination of these tell-lights is controlled by means of a cam-operated switch assembly '46 mounted on the frame 24. A portion .of rock shaft 22 projects outwardly beyond the frame as seen in Fig. 1, and has fastened to it suitable cams which cooperate with respective switches Zinhssem'bly .46 to cause illumination of the appropriatepanels-44 of theindicator device. Connection between the switch assembly 46 and the indicator 42 .is provided by ,a suitable electrical cable 48.

The cam-operated switch assembly 46 is .shown ;in greater detail in Figs. 3 and .4 of the .drawing. .Asseen in'Figs. '2 and 3, it is protected from :bein-ghit bya ball by a rubber sheathed guard 49. -..In Fig. 1, .the guard has been omitted forpurposes of clarity. This guard and the switch assembly are carried on a mounting bracket or plate 50 which is conveniently secured to the underside of the upperA-frame member 35 by the same bolts .52 which secure the bearing :block 34. Plate Stl supports four snap-action switches54, 56, 58 :andtheach of which-issecure'd to-the plate by an angle 62. Each of these switchesis provided with a roller type plunger 64 which projects .from the respective switch housings toward the center ofshaft 22. These plungers are spring biased to their extended positions .but are depressed by engagement of a cam lobe. For this purpose, there .is mounted in spaced relation on shaft 22 four collars 66, 68, 70 and 72. These are held in position on the shaft by suitable set screws which permit them-to be adjusted angularly about the shaft as wellas longitudinally thereof. Each of these collars carries cam means :which cooperate, respectively, with theplungerst64ioftrespective switch units 54, 56, 58 .and60.

As seen in Figs. through 7, 'the cam.means provided on-collars 66, 68, and 70 compromise sets of studs or pins .74, eachset comprising two :angularly spaced pins which, in the neutral .or home position of the target drum,.are :disposed atequal rotative distances from the line drawn between plungers 64 and the center of shaft 22. In the case of collar 72, the cam means carried by the collar comprisesa block "76 (seeFig. 3) which has a central depression corresponding with the contour of the roller on plunger 64 of switch unit 60. As will be apparent from the foregoing, rotation 'of-shaft 22 in either direction from neutral position will first cause cam'block 76 to depressplunger-64 of switch unit 69, thereby actuating that switchto-closed-condition. "-Further angular displacement of shaft 22 will next cause one of the studs'on collar'70 to actuate the plunger of switch unit 58, as seen in Fig. 7. Still further rocking of shaft 22 will cause actuation of the respective plungers of switches 56 and 54 successively, as seen in Figs. 6 and 5, respectively.

.As previously mentioned, the switch assembly 46 is connected to indicator 42 by a suitable multiconductor cable 48 and the tell-lights-in the indicator are illuminated in accordance with actuation of the severalswitches. The electrical circuit by which this is accomplished is shown diagrammatically in Fig. 8. As there seen, electrical power is supplied through power .mains 80 and a double pole 'disconnectswitch 82 to a step=down transformer 84. This latter supplies low voltage power for the indicator circuit. Housed within the indicator 42 is a relay panel comprising a set of'four latching type relays 86, 88, 9t), and 92, each one of which is associated with a tell-light 4, 96, 98 and 100, respectively. These are conventional relays, such as Model SIBXX manufactured by Struthers-Dunn, Inc, Pitman, N. Y. Each carries a set of normally open double pole single throw switch contacts, relay 86 having contacts 102, 104; relay 83 having contacts 166, 1%; relay having contacts 110, 112; and relay @Zhaving contacts 114, 116. Upon energizing the respective closing coil RC1, RC2, RC3 or RC4 of each relay, the contacts are closed and mechanically latched in this condition; energization of the respective unlatching coil 1C1, LC2, LC3, or LC4 trips the latch and allows the contacts to spring back to normally open position again. The tell-lights are those indicated previously which illuminate the respective indienter and are controlled by the relay contacts. Also associated with-each of the relays, being located in'the circuit of the respective relay closing coils, is one of the switch units 54, 56, 58 or 60 actuated by the ranking of shaft'22. The indicatorcircuit also includes a manually operated tell-light clearing or extinguishing switch 118.

When the game device is .in use, the power disconnect switch 82 is first closed to energize the step-down transformer 84. This places the indicator :system in condition for operation, but nothing occurs until the target has been struck by a baseball. Assuming that a ball strikes the target so as to cause a slight rocking movement just sufiiciently to depress the plunger 64 and close switch 6t electrical power is then supplied tooperating coil RC4 of relay .92 through the hot" lead 120, switch 118, lead 122 and switch 6% to one side of RC4, and through the common return or lead 124 to the other side of RC4. Energizationof this operating coil causes contacts 116, 114 to be closed and latched in the circuit-closing position. Closing of contacts 116 immediately completes a circuit to tell-light 100, illuminating this light, through leads C120, manual switch 118, leads 126 and 128 to .one side of the light, and throughlead 130 and common return 124 to the -.other. The tolllight stays .lit, due to the ,latching of relay 92, even though the target drum returns to home positionaiter the impact of the hit. The score indicated for such a hit is therefore 54 and this continues .to register until the player or another person depresses :the manual clearing switch 118. ,This action completes the circuit 10 the latch releasing coil ,LC4 ,,of .relay "92 through leads 120 and 132to one side of ,thecoil, and throughleads 134, v124, to ,the other side. Thereupon the switch contacts 116 are again openedandtell-light .100 is extinguished. In the case of relay -92, the companion set of contacts 114 isnot used.

Assuming that a hit upon the target is somewhat farther away from center than in the previous example, the target and shaft 22 will rock a greater distance :and this will cause the respective plungers 6410f switches 60 and 58 to closethose respective switches :momentarily. Closing of switch '60 illuminates :tell-light as .just described, and the closing of switch158 will likewise illuminate tellelight 98, through closing of contacts 1120f relay 90 in similar fashion. In this;c ase ;also,-the companioncontacts ,110 of relay- 90 complete .acircuit to the hot side of operatingcoil RC4 of relay ,92 through lead 136. This is a feed-back circuit -to assure that the preceding tell-light in the;lighted ,in case the first switch, normally operating that tell-light, :wasv actuated so rapidly as to fail to causelatching of the respective relay in its operated position.

The indicator system now shows tell-1ights;10.0 and 98 :both illuminated. In the simple form of indicating system :here employed, the player will understand that the score which he;receiv es for his hit is thelower of the two-numbers registered on theindicator.

It will be apparent from the foregoing that hits upon the target at successively greater distances from the central axis will cause greater swinging movement of the target about the axis and will therefore operate more of the switches in assembly 46 in succession. In such case the indicator 42 will register successively lower scores. Each time a score has been noted, it is then extinguished by depressing the manual switch 118 to clear the indicator for'the next throw.

As previously mentioned, the foregoing target device represents a very simple arrangement embodying the invention. Such a unit is readily constructed at extremely low cost and yet affords a very entertaining device. It will be obvious, however, that this very simple form of device has certain limitations which, for some purposes, may be undesirable. Chief among these is the fact that while it is capable of indicating the accuracy of the throw in respect to elevation, it cannot register the deviation of a throw in azimuth. It is relatively easy, however to adapt the foregoing device to overcome this limitation, as is illustrated in Figs. 9 through 12 of the drawings.

Basically, the modified form of the target device shown in these figures is closely similar to that previously described, the chief difference being that the mounting for the target drum includes means for permitting angular displacement about a vertical axis, as well as about a horizontal axis, and for indicating the deviation of a hit from that vertical axis.

As in the previous example, a target drum 220 is mounted upon a horizontal shaft 222, the latter being carried adjacent its ends in bearings 223 to permit free movement of the drum about the axis of shaft 222. A pipe frame 224 supports the bearings substantially as before, but in this case frame 224 is carried centrally upon the upper end of a vertical shaft 226. The latter in turn is journaled in upper and lower bearings 227, 228 (see Fig. 12) which are retained in a vertical housing or sleeve 229. In this manner the drum is provided with a gimbal mounting, permitting it to swing about either a horizontal or a vertical axis or both.

The vertical housing 229 is secured to a base or platform 230 to mount it in upright position. 'At its lower end, shaft 226 is reduced to provide a shoulder 231 which rests upon the inner race of bearing 228. As seen in Fig. 12, bearing 228 is seated in a recessin a plug or block 232 at the lower end of the housing 229. Bearing 228 thus acts as a thrust bearing for the load on shaft 226. Bearing 227 at the upper end of the housing is retained therein by means of a collar 233 held in the housing by suitable set screws.

In addition to the upper bearing within the upper end of housing 229 there is provided a pair of flat spiral springs 234, 236. One end of each of these is secured by screws 238 to the interior of the housing 229, while the other end is secured within a slot or recess 240 in shaft 226. Springs 234, 236, are wound in opposite directions, and each opposes the action of the other upon rotation of the shaft, thereby yieldingly resisting the rotation of the shaft in either direction and serving to return the shaft to a fixed or home position.

At the left hand end of shaft 222, as viewed in Fig. 9, a cylindrical housing 242 is fastened to frame 224 by means of a bracket 244. Within this housing there is a set of counter-acting flat coil springs, similar to springs 234, 236, just described, which engage shaft 222 and resiliently retain it in, or return it to, a fixed position corresponding to the home position of the target drum in respect to the horizontal axis. Housing 242 also serves a further purpose namely, that of being a counter weight to offset the weight of switch assembly 246 at the right hand of the shaft, so that the target device isbalanced about the vertical axis.

The modified target device again includes a switch assembly 246 which is identical in all respects with assembly '6 46 shown in Figs. 1, 3 and 4. Also, a visual indicator device 248, similar to indicator 42, is connected to the switch assembly by a multiconductor cable 249. This switch assembly functions, just as in the previous example, to indicate the angular displacement of the target by a ball striking above or below the horizontal axis.

In addition to the foregoing switch assembly 246, the device shown in Figs. 9 to 12 includes a second, similar assembly 250 located adjacent the lower end of shaft 226. A portion of the lower end of housing 229 is cut away to expose the shaft thereat, and cams on the exposed section of the shaft cooperate with this switch assembly to cause actuation of the latter in accordance with the extent or amount of rotation of this shaft about its vertical axis. To this end switch assembly 250 is supported by a bracket 252 secured to base 230. The switch assembly comprises four plunger-actuated switch units 254, 256, 258 and 260, and these are operated by respectively cooperating cam means on collars 262, 264, 266, and 263 which are secured to shaft 226. As seen in Figs. 13 through 16, the cam means provided is identical with that previously shown and described in connection with Figs. 3 and 5 through 7. A cable 270 makes connection between the lower switchassembly and the visual indicator 248.

As an optional refinement, the target device here illustrated includes a single, plunger-actuated switch unit 272, identical with each of the individual switch units previously mentioned, unit 272 being held by a clamp 274 on horizontal shaft 222 within drum 220. This is illustrated in Fig. 11 from which it will be seen that the switch is held by the clamp so as to cause the roller 276 of its plunger 278 .to lie just behind the membrane 280 of the dnum in the area corresponding to the bullseye. A ball striking the target on absolute dead center, both in respect to the vertical and horizontal axes, will obviously not cause the drum to tip. No indication would thus be registered on the visual indicator 248, but by providing the supplemental switch 272 just described, the local defiection of the membrane, upon being hit by a ball, will cause actuationof the switch. As will presently be explained, this switch is so connected to the indicator circuit as to provide a means of recording a hit on dead center.

While it would be entirely possible and perhaps even desirable in some cases to use separate visual indicators for registering tilting movement of the target drum about its horizontal and its vertical axes, the present embodiment incorporates a single indicator which provides a composite registration of the accuracy of the hit with respect to both the vertical and horizontal axes of the target. The electrical control circuit diagram for such an indicating system is shown in Fig. 17. As will be seen, this circuit differs from that shown in Fig. 8 only by the addition of switches 254, 256, 258, and 260, which are connected in parallel, respectively, with switches 54, 56, 58 and 60, and by the addition of the supplemental switch 272 which is also connected in parallel with switches 60 and 260.

Since the functioning of this circuit is the same in all material respects as that previously described in connection with Fig. 8, it will not be necessary to go into any great detail on it here. It is believed sufiicient merely to point out that by reason of the pairing of switches, whereby one actuated by a given degree or amount of movement of the target about one axis is connected in electrical parallel with another actuated by a similar degree or amount of movement of the target about the other axis, results in the registering of a composite score. Thus, for example, where a ball strikes the target directly on the horizontal axis, for which a score of 4 would normally be received, but at some distance from the vertical axis, for example, corresponding to a score of 2 in respect to that axis, then the net score for that throw will be the smaller figure, namely 2. It will be seen that in such a case, the indicator will have the numbers 4, 3 and 2 all illuminated, in the circuit design shown in the ac- .a' companying diagram, and the player will vknow that the smallest number illuminated represents his score.

In the case of a direct :hit at the .center of :the .bullseye, thereby closing switch 272, just the number 4 will be :lighted. The same result is obtained if a ball strikes the target so nearly on centeras to cause .actuationof either or both of switches 60 and/or 260, but no others. If desired, provision may easily be made whereby a hitdead center, i.e,.one causing actuation of switch 1272 only, may causea separate indication, either'visual or aural, to be energized. As will be obvious to those skilled in the art, this can be conveniently done by disconnecting lead 282 from itsconnection to switches'60 and 260, and running it instead to-a separate light, bell or similar device 'toigive a momentary indication.

,Many other modifications of the indicating system will be apparent from the foregoing description. As has already been suggested, separate indicator devices may be employed for each switch assembly; also, quite easy by making a small change in the relay circuits-shown in Figs. 8 and '13 to have the cam-operated switches effect extinguishment of the tell-light previously lighted by a preceding switch in the sequence of operation, whereby the indicator will show only the last or smallest score registered.

Modifications in the mechanical construction of :the target device will also be apparent, as the frame or standard specifically disclosed here for purposesof illustration is intentionally simplified. Yet a unitconstructed exactly as shown has proven entirely practicalzand has the decided virtue of being rugged and able to Withstand considerable abuse without adverse effect uponits operation. Moreover it is relatively economical to.construct. Mention may also be made of various other :means for resiliently biasing the target in its home or neutral position. For example, regular extension springs connected between the lower edges of the drumandmembers of the'frame 24 or 224 may be substituted for the means shown to maintain the drum normallyerect in respect to rotation about its horizontal axis, and similar means may be employed to position the target .in its vertical axis.

The foregoing embodiments of theinventionare, therefore, to be considered in all respects as illustrative and not restrictive, and all changes coming within the meaning and equivalency range of the appended claims are accordingly intended to be embraced therein.
