The pane 14 is solid glass which completely covers the open side 13 of the casing 10.
The disks 18 and 19 are adapted to be revolved in opposite directions to cause the openings 20 and 21 in the different shutters or disks to aline to thus allow rays Of light emanating from the lighting means or lamp to pass through alining openings as the shutters or disks revolve, whereby said rays of light will intermittently emanate from the open side of the housing or casing and through the pane 14 to provide intermittent iiashes Of light for producing a warning signal. A stationary axle or shaft for the shutters or disks [8 and 19 is denoted at 22. Said shaft 22 is .supported at its outer end upon the pane 14 and at its inner end fixedly carries a member 23 which provides the field, of the permanent magnet type, of an ordinary electric motor far actu ating the shutters or disks 18 and 19.
As disclosed, the outer end of the stationary shaft 22 has 'a reduced threaded extension 24 which passes through a threaded opening in an taxternally threaded fitting 25. A thumb nut 26 upon the threaded extension 24 and turned down against the tting rigidly fastens the axle or shaft 22 to said fitting. 'The fitting 25 freely passes through an opening 26111 arranged ccntrallyof the pane 14 and is held in stationary relation to said pane by means of annular, internally threaded washers 27 which are screwed on member 25 and engage the inner and outer surfaces of the pane 14. The member 23 providing the field of the electric motor has a central threaded opening 28 arranged upon an inner reduced threaded extension 23 of the axle or shaft 22 and. a thumb nut 30 upon said threaded extension 29 and turned down against the member 23 rigidly fastens said member to the axle or shaft 22. 7
The shutters or disks 18 and 19 may be of any. preferred material suitable to their purpose. Said shutters or disks are spaced apart slightly and are mounted upon the stationary axle or shaft 22 to be perpendicular thereto and parallel with the pane 14. As discloSed, the shutter or disk. 18 includes a hub 31 which is perpendioular to the body of the shutter or disk and extends inwardly therefrom, said hub 31 being rotatably mounted upon the axle or shaft 22 between the member 23 and an inner shoulder 32 upon said axle or shaft. The shutter or disk 19 includes a hub -33 which is perpendicular to the body ofthe shutter or disk and. extends outwardly therefrom, said hub 33 being rotatably mounted upon the axle or shaft 22 between the iitting 25 and an outer shoulder 34 upon said axle or shaft.
. The-member or field 23 includes an annular flange 35 which concentrically surrounds the hub 31 in spaced relation thereto, and the externally threaded portion of the fitting 25 which is carried by the annular threaded members 27 is in spaced relation to the hub 33 'as will be moreclear from Fig. 1.
The stationary axle or shaft 22 can be carried solely by the pane 14 as disclosed and in turn stationarily carry the member 23 or an additional support (not shown) for said member 23 can-be provided.
- The electric motor including the field 23 may also include an ordinary type of armature 36 with insulated windings 37, commutator 38 and being designated and 41. The armature is a three-pole ai'mature and the commutator is a three-segment commutator, although the structure can be varied in this regard. The armature 36 and the corrimutator 38 are fixed to rotate with the hub 31 but separated therefrom by insulation 42 and said armature and commutator are themselves separated by insulabody of the shutter or disk 10 with the hub 33,
tion 43. The brushes 39 are insulatively inounted in the member 23, as at 44, to engage the commutator in ordinary fashion and the armature issurrouncled by the annular flange 35 of said member 23.
The lead wires 40 and 41 extend from a source of electric current supply which may be the same source as that for lighting the lamp 11. When the electric circuit including said lead wires 40 and. 41 is closed, the electric motor will, obviously, be energized and the armature 36 will thus be caused to rotate to in turn rotate the hub 31 and with it the shutter or disk 18, upon the stationary axle or shaft 22.
An annular L-shape web 45, which connects the body of the shutter or disk 18 with the hub 31, is constructed to provide a bevel gear 46 which meshes with a pinion 47 fixed upon a .pin 48 carried by the stationary axle or shaft 22. An annular L-shape web49, which connects the is constructed to provide a bevel gear 50 with which the pinion 47 meshes. The L-shape web is disposed inwardly from the body of the shutter or disk 18 and, the L-shape web 49 is disposed outwardly from the body of the shutter or disk 13 to space the bevel gears 46 and 50 apart in order that these may properly engage the pinion 47. The shoulders 32 and 34 cooperate with the member 23 and the hub 31 and the fitting 25 and the hub 33, respectively, to maintain the bevel gear and the pinion in the desired relation as will be understood.
It will be evident that upon rotation of the shutter ordisk 18 by energization of the electric motor in the manner as set forth, to revolve the shutter or disk 18, the hub 31 and the bevel gear 46, said bevel gear 46 will act upon the pinion 47 to cause this to be revolved and said pinion will in turn act upon the bevel gear 50 to revolve the shutter or disk 19 and the hub 'said shutters or disks in opposite directions,
the openings in the different shutters or disks will successively aline, `as will be apparent and. allow rays of light emanating from the lighting .means or lamp 11 to pass through the alining ti' openings as the shutters or disks relatively re- Gif" duc1ng at warning signalvolve to thus intermittently emanate from the open side of the casing 10, throughthe transparent or translucent pane 14 as shown, whereby to provide intermittent flashes of light for pro- As shown, each of the spaced apart openings 20 in the inner shutter or disk 18 is provided 'sirably being of Celluloid and attached against with a colored, translucent covering member, represented 51, said covering members 51 dethe inner surface of the shutter or disk 18 by means of rivets 52- ..Each of the covering members 5l may be a different color, or all of said covering members may be the same color, or
brushes 39, ordinary lead Wires to said brushes one or a plurality may be the same color while others are of variantcolor. SIt has been found green, one yellow and one blue.
-In Fig. the arrows indicate that the shutters or disks ia and li are travelling in opposite directions. The rays of light shine through the openings in both shutters or disks and through the colored covering members when said :shutter -or disk openings totally:or partially aline. The Shutters `Or disks 'iS and is are of course composed of opaque material, metal or fibre, ,for instance, and the effect of relative rotation of the shutters or "disks in the arrangement :as disolosed is the production of eight flashes of four different colors in four different positions for each complete revolution of the shutters or disks. Other eects too innumerable to be mentioned can evidentlybe produced, as, for example, an optical eiiect of rotation, the dead portions travelling one way and the colors travelling the opposite way, etc.
-In cases where all of the coveringmembers -5i are the Same color, the intermittent flashes of light will also be a single color. By theemployment of covering members Ell having several different colors, a plurality of different colors can be flashed through the pane Hi to produce any desired and predeterminedeffect.
It will be apparent that by varying the color scheme of the covering members EI, warning signals of a variety of different colors and combinations of colors can be produce. Also, the signalling effect can be varied by altering the relative rates of speed of rotation of the shutters or disks IB and IS. As disclosed, said shutters or disks travel at equal speed in opposite directions. Obviously, the arrangement could be such that the shutters or disks will rotate at unequal rates of speed either in opposite direction or in the same direction.
In practice, when the signal is employed as an automotive vehicle stop light signal, it may be that the lamp II is normally dark, but becomes energized, together with the electric motor of the signal, when the vehicle operator depresses his brake lever to close an electric circuit, or Circuits, including the lamp li, as well as the lead wires it and 4!. Immediately upon energization of the electric motor, the shutters or disks IB and 19 commence to revolve and upon de-energization of said electric motor, said shutters or disks immediately come to rest.
It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the cope of applicant's invention, which generally stated, consists in a device capable of carrying out the objects above set forth, in the parts combinations of parts disclosed and defined in the appended claims.
