Application filed August 3,

Be itv known that-I, EUGENE W. VO EL, a

citizen of the United States,-residing at Oak. Park, .in thecounty of Cook and State of Illinois, have invented certain new'and use ful Improvements in Highway Signaling Apparatus, of which'the following isa specification. Y i l My invention relates to an automatic slgnaling apparatusdesigned to be placed at the intersection of a highway with a railroad track to give. warning of the approach of trains, or on a 'highway or street at the approach to-a draw or lift bridge to advise the public of the opening of the bridge, or in other analogous situations. Devices of this type are commonlyca'lle'd highway signals and are used most frequently at the intersection of a roadway orstreet with arailroad track. The preferred form of apparatus embodying my invention is shown and will be described herein as located at and particularly designed for the intersection of a street or-roadway witha' railroad track.

The invention contemplates providing a signaling apparatus comprising a flag with the word Danger or other suitable legend imprinted or displayed thereon, which is carried by a flag-pole projected out laterally over the highwayfrom its support, prefer ably in'a'normal'ly horizontal position, although the position mightbe oblique, if desired, and automatically vibrated or waved up and down on theapproach of a train. In addition, one or more illuminated signals are provided, electric lamps, for example, which are lighted during the period that the fiag vibrates, the lamps preferably giving out a series of flashes. The apparatus is also provided, preferably, with a hell or other audible signal which is kept in operation during the signaling period. The particular bell mechanism which I. have shown for producing the audi-le signal to accompany the waving of the flag is claimed herein only in combination with the other features'of the apparatusgthehell mechanism, per 86, being described Landclaimed in -my application Serial No. 839363, fSignal bell for railroad 1 service, filed May 18,1914.

' 'I:he invention .hontcmplates, further, pro- 1 yidlng the apparatus with an electric motor;

for driving all of the movingparts. The invention contemplates, additionally, the provision of a spring or other suitable counterbalancing device for the inner end of the flag-pole whereby this end of the pole may.

be made short without putting too much of 'a load onthe motor. As an alternative construction'I provide two flags operated by i the same motor and arranged so that one counter-balances the other. T The lnvention provides, furthermore, an

arrangement by which the cam mechanism for vibrating or waving the flag cannot back up the motor when the current is cut off.

The object of theinvention. is to provide highway signaling apparatus havingthe improved features above. adverted to and consisting of the new and improved constructions, arrangements and devices "to be hereinafter described and claimed.

The invention is illustrated in a preferred embodiment in the accompanying drawings, wherein- Figure-1 is an elevation of the apparatus viewed as one would see it from the highway inapproaching the railroad track; I

Fig. 11, a fragmentary sectional elevation illustrating the modification above referred to, in which there are two flags in counterpoised relation.

Like characters of reference designate like parts in the several figures of the drawings.

By referring to Fig. 10 the relationship and operation of the principal elements of the invention as applied to a highway signal will be readily understood. A designates a flag which is waved or vibrated in a vertical plane by a cam B rotated through a reducing train of gears by a motor C. D is a bell having a rocking clapper E which is brought against the bell by a weight F that is ntermittently raised and released by a snail cam G driven from motor C. H designates an electric lamp carried by the flag A, and J a stationary, lamp. Either one or both of these may be employed The lamps are on a circuit K which is a shunt from the motor circuit L. Current is supplied from the generator M. N is a cam wheel driven from the motor C which makes and breaks the light circuit by efi'ecting a separation of contact 0 and P. As the lamps will ordinarily be lighted only atnight, the lamp circuit is provided with a switch Q.

The motor, and when desired, the lamps, are supplied with current automatically on the approach of a train by any suitable a paratus employed for the operation of automatic railroad signals. I have shown 'for this purpose a track circuit system. The track R is divided by insulation into two blocks 7*, r, the insulation between the two blocks being substantially at the highway S. T, T, designate the track batteries and I an interlocking relay of conventional type. On the approach of a train from the left, the left-hand magnet of the relay drops its armature closing the circuit through the generator and motor. When the train passes over upon the block 1" the left-hand magnet picks up its armature and breaks the circuit, stopping the operation of the'signaling apparatus. The armature of the right-hand magnet is held up when a train passes from west to east on the block 1*, as is well understood by those familiar with this type of apparatus. The operation of the interlocking relay is reversed but with the same effect when a train approaches a highway from east' to west.

I will now describe the mechanical construction of the signaling apparatus of my invention.

The flag and the mechanism for moving it.

25 designates a casing having a socket 26 for mounting it on a pole 27. The danger flag A is supported on a tubular stand or tion roller 32 which bearings formed in against which bears flag-pole 28 formed with gudgeons 29 mounted in bearings 30 in a housing 31 formed on the outside ofthe casing 25. The inner end of the flag-pole carries an anti-fricbears against the cam a shaft 3 3 turning in a bracket member '34 (Fig. 8) secured to one side wall of the casing 25. The bracket member has a platform 35 supporting the motor C. The shaft 33 has fixed thereon a gear wheel 36 driven from a pinion 37 on the armature shaft of motor C through a train of reducing gears 38, 39, 40, 41.

In order to lighten the load on the motor which would otherwise be considerable, in view of the fact that the inner end of the flag-pole 28 against which the'cam B operates is much shorter than the outer end, the leverage of which is further increased by the weight of fla A, I rovide a counterbalance for the shorten of the pole constructed, preferably, as follows: A coiled spring 42 surrounds and is anchored at one extremity 43 to a shaft 44 mounted in bearing blocks 45 on the side wall of the casing 25. The other end of the spring is attached at 46 to one of the bearing blocks 45. The shaft 44 has a squared end 47 for a disk 48 having a grooved perimeter formed with a series of circumferentially arranged perforations 49. The short end of the pole 28 is securedto the disk 48 by a link and pin 51, the latter being passed through one pair ofperforations 49 after the spring 42 has been put under torsional strain by the application of a wrench to the squared end 47 of shaft 44. The adjustment of the link 50 on the disk 48 will, of course, depend upon the weight of the outer end of the flag which the spring 42 is intended to counterpoise.

In order to prevent the weight of the flag and the cam B from backing up motor C if the mechanism were stopped withthe parts 110 in a position making this possible, I provide the shaft 33 with a ratchet wheel 52 a dog 53 pivoted between lugs 54 on the bracket member 34.

Instead of having a single flag counter- 115 poised as above described, it will be possible to provide two flags. A, A, as shown in Fig. 11, projecting from opposite sides of the casing 25' and driven by a pair of oppositely arranged cams B. B aflixcd to the 120 same shaft 33 and driven by the motor as above described. With an arrangement such as this one flag will be up While the other is down, so that one counter-balances the other.

The bell.

The bell D is supported on a standard 55 on the top of casing 25, the clapper E, which is in the form of a bell crank, being pivoted at 56 on the standard 55. The clapper is 131 B which is fixed to connected by a pivoted link 57 with an ope ating rod 58 to which is secured a weight 59.

The lower end of the rod 58 carries an anti? friction roller 60 which bears upon the snail cam G. v The latter is on the same shaft ,61 with a gear wheel 62 meshingjwith a gear wheel 39. An elastic pad 63 is arranged on period.

. the electric lam p H which, as shown in Figs.

the top of casing 25 to receive the weight 59; The cam G,revolved by motor C, raises the weight and then releases the'same. The Weight throws the clapper against the'bell.

The light signclsf The casing 25 is preferably formed with.

light openings, for example, one in each side, which are provided'wit h lenses 63. The

electric lampd is arranged withinthe cas mg so as to pro ect beams'of light through the lenses 63. (which may be suitably colored, if desired), during the signaling I also preferably providethe flag itself with'one or more lights, for example, with 1 and 2, is arranged at the outer end of the flag-pole 28 in a spherical casing 64 which is providedIwith-lenses 65. The 'wires ofthe light circuit Kextend through the tubular portionpffthe flagpole into the casing 25.

Preferably the light signals are of the flashingtype. To this end an interrupter is provided for the light circuitwhich is operated from motor C. iKeyed tofishaft 33 is a metal disk 66,130 whicl1-is-secured,"by

' 7 screws the'fi'ber-cam wheelN having on its perimeter thesteel cams 68 which operate against a..roller-,. 69-. (Figs. 5 and 6 attachedf to a spring membfer. 70. anchored at oneend 71 to thebracket member 3a and carrying at its opposite end a carbon contact block 72 which, is brought against a carbon block ",tion, Therefore 'I do not wish to be understood as llmlllll'lg the invention to such par- 73 secured to a terminal plate 7:4 havinga binding post 75 for the light circuit wire,
