To all whom t may concern:

Be it known that I, OSCAR BROWN, a citizen of the United States, residing at Lula, in the county ofHall and State of Georgia, have invented new and useful'lmprovements in Highway-Crossing Signals, of which the following is aspecication. f The object of the invention is to provide a relatively simpleand comparatively inexpensive grade crossing signaling device adapted for operation by approaching trains of which the'wheels are adaptedby Acontact with a trip, suitably located, to cause such operation of the signal as to serve as a warning to pedestrians and drivers following the cross road, sufficiently in advance of the train to avoid the accidents which are common to railway grade crossings, and with this object in view the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings, it being understood that changes in the form, and proportion may be resorted to, within the scope of the appended claim, without departing from the princi les involved.

In t e drawings:

Figure 1 is a plan view of a signaling apparatus applied in the operative position to\ a section of railway tracks, and indicating in intersecting relation therewith a grade crossing or highway.

Fig. 2 is a side view of the same.

Fig. 3 is a `detail side view showing the visual signaling standard turned to the position to which it is moved by contact of the train wheels with the trip.

Fig. 4L is a detail sectional view to show the relation between the crossV arms by which the visual signal is operated and by which the portable signal is sounded.

Fig. 5 is a detail view of the trip showingtrack rails and holding a signaling flag 13 or other visual signaling device which is normally held extended transversely over Specification of Letters Patent.

the line of the track but which is adapted to be turned to a position extending across the intersecting highway 10, so as to give a warning signal -to a pedestrian or driver approaching on the latter, and to this end said standard-is provided with a spindle 14 mounted in a suitable bearing 15 ina boxing o'r housing 16 supported by or secured in a permanentmanner tothe cross ties of the roadi Connected with the spindle of the standard is a return spring 16 adapted to hold the standard usngly in vits'normal or face position while connected to the standard at a convenient distance above the level of the tie is a cross arm 17 from which extends a tension rod or wire 18 adapted to be carried along the track parallel with and preferably close to one of the rails for attachment to and operation by a trip 19 which should be located for example about 300 ft., or more from the crossing. In the construction illustrated, this trip consists of the spindle 2O mounted in a suitable bearing which may be formed in the rail as shown at 21, from one end of which depends an arm 22 for connection as by suitable cushioning springs 23 with the tension rod or wire, and a trip arm 24 preferably provided with an anti-friction roll 25 which is arranged in such a relation to the tread of the rail as to be engaged by the flange of a passing entire wheel.

Connected with the trip is a return spring 27 or the equivalent thereof for normally holdingr the same in its position with the contact roll in the path of a wheel flange and adapted to return the trip promptly to said position upon the release by a wheel, the vibratory movement of the trip caused by the successive contacts of succeeding wheels with thel trip roller serving through mon at grade crossings.

Conveniently located, either-iin or lon the n casing or housing as shown in the drawing is a signal bellor gong 28 adjacent to which is located a pivotal lever 29 forming a ham- Vibrated said arm comes incontact with the cam and *thus actuates the hammer or lever to sound the bell. This methodof signaling serves to supplement the visual signal'in attracting the attention of an approaching pedestrian or driver andunder normal circumstances insures the checking 'of progress in time toavoid the accidents which' are com- It will be obvious that suchan apparatus as described canbe applied to a railway atl a minimum costboth as to installation and maintenance, inasmuch as thereis no com- Y plioated mechanism to get out of order or which may possibly -be interfered vwith by accumulations of snow and ice and the like.

Y Having thus described my invention what I claim asnew is':+'

A railway crossing signalingdevice havinga Vbase,a standard revolubly mounted upon the base and provided withV a lateral signaling arm and a depending spindle, a spring connected with said spindle for yield'- ingly holding the-standard in its normal position, a cross arm carried by the standard, a trip arm having a roller `arranged in the pathpofwheels traversing the track rails, yielding means for vholding said trip; in its 'normall position7 connections between said ,trip and the cross arm of the standard and having cushioning spring attachmentto the latter, and an audible signaling meanscarried by theibaseand'having anoperating arm movable-in YaY plane perpendicular to and provided with-acam arranged in the path of movement of vsaid cross arm;V
