HONOLULU, TERRITORY OF GAME mmcAtron' I Application filed January as, 1927. Serial No. 164,246.
This invention relates to indicating devices and more specifically to indicators adapted for use at football games.
As is commonly known, in playing the game of football of the present day, the team carrying the ball is allotted four plays in which to advance the ball tenyards. The
' playing field is marked with transversely exanother ten It is the duty of the referee to keep count this application' Fig. 2 is a transverse section taken later tending lines spaced at ten yard intervals. The termination of each play is called a down, and linesmen are utilized for the purpose of more or less accurately determining and indicating the yardage gained on each playor downy If the necessary total of ten yards is not gained in the four downs the ball passes to the opposing team. If the ten yards is gained however, the teamcarrying the ball retains possession thereof, and 1s allowed four more downs in which to gain yards. J
of the number of downs, whilethe linesmen are measuring the aggregate yardage and,
during very exciting games, disputes often arise as to the number of the down just played, the umpire, the referee and the linesmen deciding the pointbetween them, thereby materially delaying the game. 7
Many thousands of spectators customarily view the football games of the present day, and a very large majority of them are vitally interested in the number of the, downlast played or to be played. After each down the linesmen place a staff along the edge of the field in line with the position of the ball,'and the spectators are thereby advised as tothe necessary yardage to be made Without sacrifice of the ball, but have no means of being positively informed as to the numberofthe down.
The object of the present invention is the provision of means whereby to'indicate to the ofiicials of the game, and to the spectators in all parts of the field, the number lofthe down last played or to be played. 4
Other objects of the invention will be made apparent in thefollowing specifications when taken in connection with the accompanying part thereof.

Fig. 3 is a side plan view, with one side of the casing and the proximate indicating cylinder-removed, and, i
Fig. 4 is a perspective view of a guard used to cover a portion of the gear-teeth carried by the indicating cylinders. Now referring specifically to the drawings, in. which like reference characters indicate like parts throughoutthe severalviews, A is a housing, preferably of. rectangular formation and formed of sheet metal,and B, C, D and E are tubular cylinders axially rotatable within the housing A, it being noted that each cylinder is mounted on a shaft extend; ing therethrough, the shafts being indicated by b, 0, d and 6. Each of the'shafts preferably extends through bearing platesl and 2 provided with a track for anti-friction vrollers, as best shown in Fig. 3, nuts 3 and 4 being provided at the protruding ends of the shafts, as illustrated. Each of the cylinders 13,0," D and E :is
provided on itsrlowerrsurface with a spur gear 5, preferablycut'from a hard fiber disk,
thete'eth 6 of thegears 5 extending laterally beyond the body of the'cylinder and intermeshing with, the teeth on the gear 5 of the adjacent cylinders, whereby rotation of one cylinder will cause an oppositely directed rotation of the adjacent cylinder, as'will be understood.
Each side face of the casing A is provided with an opening or cut-away portion 7, about 5% inches wide, through which the rounded wall of the cylindersmay project, as illustrated, and each cylinder sequentially carries on its quarter faces, the numbers 1, 2, 3 and 4. It is to beunderstood however that, if cylinders B and D are rotating in one direction, the cylinders C and E are rotating in the opposite direction, and consequently,
since itis desired that the 'samenumbers 4, while on the eylindersC and E will run reversely, or from 4' to '1. u 1 1 As here shown, cylinder B is the master cylinder,the shaft bythereof being fixed to the gear 5, and extending. downwardly through the floor of the housing A, and terminating in an offset portion8, carrying an operating handle 9. Thehousing A is centrally provided on its bottom surface with a staff 19 carrying a pointed. metallic lowen no a end 11,adapted for insertion into the ground.
- The "staff 10 is of a length such that, when the lower end 11 rests upon or in the ground, the housing A isabove' the head ofthe ordinary linesman Who carries the device. 12 extends laterally from the staff 10, the
outer end of said bracket forming a: bearing for the shaft 1) of the cylinder Directly above the outer end of the bracket 12'and'su'pported thereby, isa smaller indicator 13 fixed upo the s a t 1- he n icat 13 is p erably of cylindrical configuration and carries on its outer, surface the numbers 1, 2, 3 and 4 arranged inthe order ofthe numerals carried by the master cylinder B. Since the indicator 13 is rotatable with the shaft 6,
which, in turn rotates'yyith the cylinder B, it
fe lows th t, W h'th numb rs r ng as above set forth, When-the number 2, for instance, is exposed through the opening 7 on the cylinder B, thesame number will be facin in the sarnev d irection on the indicator 13.
