FURMAN D. SPEAR, OF NEW YORK, N. Y., ASSIGNOR 'IO ARMSPEAR MANUFACTURING- COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW YORK.
Tojdll who ifz't may concern Be, it known that I, FURMAN D. SPEAK, a
\ citizen of the United States of America, re-
siding at New York city, county and State of New York, have invented a newand useful'Tralfic- Signal, of which the following is a specification.
invention relates to a newa-nd useful traffic signal, the object being to provide a signal equally'useful and availablefor day -or night service and which in its preferred form by light, shape, color and word, gives the desired signal indication to go, or stop. I
- In the'accompanying drawings:
1 Figure l is a side elevation of the complete device on a small scale and broken away at the center.
Fig. 2 is a similar view of the same parts in a different position. Fig. 3 is a horizontal section on the line 33 of Fig. 1.
Fig. 4 is a sectional view of a lens detached.
1 represents the base of a suitable lantern having two sets of diametrically opposed red and green lens sectors.
the'red'sectors, while 3 3 represent the green sectors. These lens sectors are preferably of the spheroidal type designed to:
project an intense' beam of substantial height, although it is not essential to the invention that any particular form of lens be employed. Bisecting the green lenses 3-3 are twosemaphore plates or arms 44 carrled .by the lantern. Bi-secting' thered lenses 2-2 are two semaphore blades, plates -or arms 5 5. Between the several lenses I preferably locate guard plates 6+6. The semaphore arms are all radial to the vertical axis of the lantern. 7 is the head of the lantern. The, lantern may be illuminated by an oil lamp or an electric ,lamp or any other illuminant, as desired. 8 is a pedestal which supports the lantern and its associated parts. This pedestal 8 is rotatably mounted "in a suitable base or standard i9. 10 is a handle on the pedestal 8 by which the lantern audits associated guard lates and semaphore arms are'pref-; erablyrbraced by stiff horizontal rings 11-110 The semaphore'arms it are of a dif-" ploye' d-nfor the [at intersecting thereto and it ferentcolor, and preferably of a d-iflerent shape and size, from the arms'5. I The arms 4 should correspond in color to the lenses 2,

while the arms 5 should correspond in color to the lenses 3. If red is to designate. the danger signal, the lenses 2 and the plates 4 should be colored red. If green is to designate the safety signal the lenses 3 and the arms 5 should be colored green. The semaphore arms 4 ma words Stop, While the semaphore arms a may bear the wordsfGo. ,By placing the lantern in substantially the same horizontal furthermore bear theplane with the semaphore arms 4 and 5 the light from the lantern illuminates the arms so that the words and shape may be .observed, the color the lens or glass.
By the use of this apparatus the officer in charge of traffic conditions at two cross roads may turn the signal so as to indicate'with definiteness, either in the day time or in the night time, over which road vehicles shall have the right of way; i
The signal may be detachabl'y connected to the top of the pedestal by any suitable no part of the lenses 33 will be visible to signal being furnished by v shown in Fig. 1,.
the one approaching. So also, whenthe signal is turned degrees, or to the position shown in Fig. 2, the guard plates will hide the lenses 2-2 so that only the desired warning light will be exposed to the one approaching thereby avoiding all possibility of "confusion. These guard plates are not essential to my invention in its broadest aspect.
It should be understood that I use the term .lens in a broad enough sense to include any class, .or the like. While I prefer to use what are now the conventional colors to denote danger and safety, namely, red I do ,not intend to While my invention, as shown in the drawings, is of particular utility as emroads, its utility is not limited may be employed in many purposes of. traffic signaling.
other connections for signaling purposes, traffic and otherwise, and the special'method of mounting, supporting and operating the same may be modified at will.
What I claim is: j
1. Ina traific signal of the character described, a lantern having two sets of lenses of different colors, one set being arranged in a plane at right angles to the other set, one set of oppositely arranged semaphore arms carried by said lantern and bisecting the lenses of one set, and another set of dif ferentlyshaped oppositely arranged semaphore arms bisecting the lenses of the other set, and a rotatable support for said signal.
2. In a traflic signal of the character described, a lantern having two sets of lenses of different colors, one, set being arranged in a plane at right angles to the other set,
two oppositely arranged semaphore arms carried by said lantern and bisecting the lenses of one set, and two other oppositely arranged semaphore arms bisecting the lenses of the other set, guard plates be tween said lenses extending outwardly fromthe lantern, and a rotatable support for said signal.
3. In a 'trafiic signal of the character de y scribed, a lantern having two sets of lenses of different colors, one set .being arranged in a plane at right angles to the other set, two oppositely arranged semaphore arms carried by said lantern and bisecting the lenses of scribed, a lantern having two'sets of lenses of different colors, one set being arranged in oppositely arranged semaphore arms carried 'by said lantern and bisecting'the lenses of one set, and-two other oppositely arranged semaphore arms bisecting the lenses of the other set.
-5. Ina trafiic signal of the character described, a lantern having two sets of lenses of different colors, one set being arranged in a plane at right angles to the other set, two oppositely arranged semaphore arms carried a plane at right angles to the other set, two
bysaid lantern and bisecting the lenses of v one set, and, two'other oppositely arranged semaphore arms bisecting the lenses of the other set, said lenses and arms being in substantially the same horizontal plane.
