5 Claims.

The invention relates to the game of football and more particularly it is an object of the inmention to provide a device for indicating the downs in a football game.

As is well known, in the past few years it has been becomin increasingly opular to play the game of football at night; Professional teams as well as the football teams of educational institutions are finding it possible to draw larger crowds at night games.

As is also well known, it has been the custom in both night and day football games for a linesman to indicate the downs during the progress of a football game by means of a short pole having a square box at its upper end. One end of the pole is rested upon the ground and as the game progresses, the box is rotated for alternately disposing. differently numbered sides of the. box facing the players: and: officials. By reading the number so displayed, the players and officials are able to ascertain. which down is about to be pl yed.

While these numbered. boxes have been sucoessful in the past for daylight football, they have been extremely difficult to see from the grandstand at night. A particular disadvantage has been thatin. the prior practice the down numbers have not been visible to the audience because the lineslnan usually stands between the down-box and the. audience and further because the proper number has always been disposed toward the playing field only.

It is therefore an object of the invention to provide a down indicator which is visible to the audience as well as to the players and officials. It isalso an object of the invention to provide an illuminated down indicator for greater visibility at night.

Another object at the invention is to provide a down indicator employing a row oi spaced apart lights, the latter being. more easily distinguished when the indicator is viewed ata distanc than would be possible if only the numbers of the downs were themselves illuminated.

Another object of the invention is to provide a down indicator as described. having lights oi variegated colors each indicating a different down.

A-iurther object of the invention: resides in the provision of a down indicator having a row of spaced. apart lights whiehare shielded from one another so that they do not tend to seem blurred together when viewed at a distance.

Yet a further object of the invention resides in the provision of a down indicator as described employing batteries and being of such a construction that the latter may be easily replaced at desired times.

A particular object of the invention resides in the provision of a down indicator as described which is substantially waterproof so that it is not affected by rain during use.

Still another object of the invention resides in the provision of a down indicator as described which adds to the attractiveness of night foot ball games as well as facilitating the understanding of the game by the spectators.

A further object of the invention resides in the provision of a down indicator employing a plurality of lights, further havin convenient means for switching the latter on and off;

Yet another object resides in the provision of a down indicator as described which is strong and durable in construction, reliable and efficient in operation, and economical in its manu facture and maintenance.

Other and still further objects and advantages of the invention will become apparent from the following detailed description thereof.

In the drawings:

Figure 1 is a pers ective View of the down in- 5 dicator of the invention shown in the upright position of use;

Figure 2 is a frontal elevation of the m:id-sectiori of the new device with its front door-panel removed, the view being taken by removing that panel shown in. Figure 1 which displays the nu- 5 of appearance and for providing a pointed lower end for convenient insertion into the surface of the ground so that when: desired,- the lower end of the standard may be rammed into the ground for maintaining the standard upright without other support.

At the pper end of the standard I0, a plurality of light sources, or lamps i4, I6, I8 and 20 are provided. The latter are spaced apart and are disposed in a row one above another and in alignment with the standard it.

The lights I4, I6, I8 and 20 are preferably four in number for indicating the four downs or chances of the side possessing the ball to advance the ball I yards in order to retain possession of the ball.

The lights are preferably each of a different color so that they are more readily distinguished by the audience. Each light preferably comprises a shield or base 22. The bases 22 are each of hemispherical shape and contain a socket and electric light bulb. The shields 22 are opaque so that the light rays emanating from the bulb contained in each of the bases is shielded from intermingling with the light from the next lower bulb at the source of such light rays, or adjacent the down indicator.

The bases 22 are disposed with their open sides disposed upwardly, as shown in Figure 1, or transversely of the standard I0. An outwardly flared flange 24 surrounds the upper end of each of the bases 22. The flanges 24 are provided with'circular grooves on their inner side for receiving a translucent dome 26.

The domes 2B are each of a different color as previously described and are firmly held by the flanges 24 in a water-tight manner so that rain cannot enter between the domes 26 and the flanges 24. If desired, the domes 26 can bemade of colorless and transparent material and the bulbs contained therein can be colored.

The lights I4, I6, I8 and 20 are maintained equidistantly spaced apart above the standard I 0 by means of a plurality of elongated frame members 30, preferably three in number. The frame members 30 are disposed in parallelism extending upwardly and in parallelism with the standard I0. At their lower ends, the frame members 30 are welded to and are equidistantly spaced about the circumference of the flange 24 of the lamp or light source I4.

The standards 30 are each welded to each one of the other flanges 24 in similar manner. At their upper ends, the frame members30 extend upwardly past the upper light source 20 a short distance. The upper ends of the frame members so are bent inwardly toward a center and are there welded or otherwise secured together, as best shown at 36.

Each of the light bulbs in the sockets or bases the terminal buttons 95 and I04 by frame members 30 and enter an aperture 43 in the upper end of the hollow standard I0, travelling downwardly through the latter as best shown in Figure 2. At their lower ends the terminal wires 42 emerge from the standard I0 through an aperture 44 in the standard, the aperture 44 is disposed on the inside of a display member or number-box generally indicated at 50 in all figures.

The number-box 50 is preferably four-sided having a square top 52. The edges of the top 52 are down turned and are soldered or otherwise secured to three

side panels

56, 58 and '60. The other or forward edge of the top 52 is dis 4 posed forwardly toward a door panel 62 of the box 50. The said forward edge of the top 52 is doubled back upon itself, as best shown in Figure 2, for finishing the edge.

The top 52 is provided with a row of spaced apart apertures extending in parallelism and spaced inwardly from the door panel 62. The said apertures are for the purpose of receiving a plurality of switches having bases shown at 66, 68, I0 and I2.

The switches are four in number and are each provided with a throw lever I4, I6, I8 and 80, respectively. Each of the switches is provided with two terminals 84, one terminal 84 of each being attached to the lower terminal end of one of the wires 42, which latter extend into the aperture 44.

The ther terminal 84 of each of the switches is interconnected with a like terminal on each of the other switches by means of a wire 86. The wire 86 in turn extends downwardly in front of the back side 58 of the box 50. The wire 86 is insulated from the back side 58 by an insulation panel 88 which latter is formed of a flat sheet of insulating material extending in parallelism with the back side 58. 1 i

The wire- 86 extends downwardly between the insulation panel 88 and a terminal button board 90, which latter is also formed of insulating material and extends in parallelism with the back 58, being disposed/forwardly of the wire 86 and of the insulating panel v88.

At its lower end, the wire 86 extends to and is interconnected with a wire 92 which intercom nects a pair of spaced apart terminal buttons 95 which latter extend through the terminal button board and are disposed extending outwardly therefrom toward the interior of the box 50.

The terminal buttons 96 are spaced apart on opposite sides of the box 50 and are disposed equidistantly spaced upwardly from the bottom I00 of the box.

The button board 90 is also provided with a second pair of buttons I 04 which latter are similarly equidistantly spaced upwardly from the bottom I 00 with respect to each other. The buttons I04 also extend through the button board 90 toward the interior of the box 50. Any suitable means, not shown, may be employed for securing the button board 90 and insulation panel 88 to the rearward side 58 of the box 50.

The purpose f the buttons 96 and I00 is to make contact with two similar pairs of buttons I06 and I08 which latter form the terminals of a pair of batteries H0 and H2.

The batteries I I0 and I I2 are preferably of the common dry cell type and rest upon the bottom I00 of the box 50, being held in place against means of a push-bar I20.

The push-bar I20 i elongated and is provided with an aperture at its center of a size for the reception of a bolt I22 which latter is suitably secured at one of its ends to the standard In at a point disposed between the batteries II 0 and H2. The bolt I22 extends forwardly toward the door panel 62 and at a right angle with respect to the standard I0.

The bolt I22 is provided with a wing nut I24 thereon for the purpose of bearing against the push-bar I20 to maintain the batteries I I0 and I I2 in position. I

A wire I30 is secured to each of the terminals I04 between the terminal board 50 and the insu lation panel 88, The wire I30 is in turn secured to a wire I32 whichfextends upwardly from the wire {30 and through an aperture I34 in the terminal board 90.

The upper end of the wire I32, then is secured to the standard ID for grounding the wire I34 and placing the latter in electrical connection with the grounded wire ti! of each of the light sources I4, I6, I8 and 23. l l

The bottom member lilii of the box 50 is provi-ded with a plurality of upturned edges Mi! which are welded or otherwise suitably secured to the

sides

56, 58 and SI]. The forward edge of the bottom It!) is turned upwardly and doubled back upon itself to form a finished edge M2, as best shown in Figure 3. The sides 56 and Gil of the box are turned inwardly at their forward ends for short uniform distances to provide parts of a vertically disposed track I50.

A pair of elongated track members I52 are provided and are constructed of a right angular shape in cross section for disposing one arm thereof spaced apart from and in oppositely disposed parallelism with one of the tracks I56. The other arm of the track members I52 is disposed between and secured to the upturned edge MU of the bottom I69 and the adjacent side 55 or 50 respectively of the box 50.

The outside of the box 50 is provided with the numbers 1 to 4 extending sequentially about the sides 56, 5S and 60 and the door panel 62.

The top 52 of the box 50 is provided with the numbers 1 to 4 placed adjacent each of the switches M, 15, I8 and Bil in sequential order.

In use at a night football game, a linesman will hold the standard ID at the edge of the playing field and opposite the position of the ball. Prior to the first of four downs, the operator will throw the switch lever M and illuminate the lowermost of the lights I4, the upper lights being oiT.

Prior to a second down, the operator will then throw the switch lever 16 so that the lights I4 and it will be on. Prior to the third and fourth downs, the

switches

78 and 80 will be respectively thrown and a resultant colorful lighting display will add to the attraction of the football game.

Simultaneously with the throwing of each of the switches, the operator will rotate the standard Ii] about its axis for displaying the proper numeral it!) for indicating a down to those spectators sitting near enough to see the numerals.

Since the levers M, I6, '53 and 853 are disposed in a row, the operator may quickly throw all levers at once for shutting off all lights after a fourth down. This may easily be done by a single motion of the hand, the switches being spaced apart so as to extend no greater distance than the length of the average mans palm.

At a time when it is necessary to remove the batteries I!!! and H2 for replacement, the door panel 62 may be slid upwardly between the tracks I50 and the track members I52 and removed from the box. The box will then be as shown in Figure 2. The wing nut I24 may then be loosened and the push-bar I 2t and the batteries H0 and H2 removed and replaced by fresh batteries.

The door panel 62 may be provided at its upper end with an inwardly turned flange extending in parallelism therewith and extending a desired short distance across the top 52 of the box 50 to prevent rain from entering the box 50.

It will be seen that this invention has provided a down indicator particularly adapted to add to the understanding and attractiveness of night football games; and of durable, economical and substantially waterproof construction.

From the foregoing description, it is thought to be obvious that a down indicator constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification including variations in the shape and size of the parts, without departing from the principles and spirit thereof and for this reason, I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as claimed.
