Serial No. 467,862.

T 0 all whom it may concern:

Be it known that I, DOCK A. I'IALL, a citizen of the United States, residing at Greer, in the county of Greenville, State of South Carolina, have invented certain new and useful Improvements in Railway-Gates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to a railway gate and more particularly to the class of automatic ally operated railway gates.

The primary object of the invention is the provision of an automatic railway gate in which the same is normally positioned dircctly across the path or bed of the track and is adapted to be actuated upon the travel of a passing train to move said gate from its normal position to a position to obstruct or close the roadway intersecting the track bed.

Another object of the invention is the provision of an automatic railway gate comprising gates arranged at opposite sides of a trackand fixed to vertical spiral members, depressible track sections arranged in the track and resting upon a bridge piece en gaging the spiral members and spring resetting means disposed below the bridge piece, the said gates being normally disposed across the track bed and upon the travel of a railway train over the track and said depressiblc rail sections will be lowered to cause the rotation of the spiral members so as to swing the gates in a position to obstruct or close a highway or road intersecting the said track.

The invention consists in these and other novel features of construction which will be hereinafter more fully described, illustrated in the accompanying drawings which disclose the preferred form of embodiment of the invention and brought out in the appended claims. It is to be understood however, that changes, variations and modi- 'fications may be made such as come )roperly within the scope of the appended claims without departing from the spirit of the invention..

In the drawings: Figure 1 is a top plan view of a railway track embodying the in vention. Fig. 2 is a front elevation. Fig. 3 is a side elevation. Fig. 4 is a similar View with the gates in a shifted position to obstruct or close a road or highway intersecting the track. Fig. 5 is a sectional view on the line 55 of Fig. 3.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

In carrying the invention into practice there is provided certain details of construction and arrangement of parts to be located in and form part of the railway track. At any point where it is desired to locate a gate of this character specified as upon the division line separating a field from the road or highway there is located a series of trans versely disposed sleepers or beams 5 upon which are mounted and secured in any preferred manner longitudinal beams or bars 6 which are disposed in the same plane or parallel with the rails 7 of the track bed which latter rails have their ends terminating a considerable distance removed from each other.

At a central point between the ends of a track rail 7 is a transverse horizontally disposed supporting beam 8 the ends of which project laterally a considerable distance to opposite sides of the track bed and rising from the said supporting beam 8 at opposite sides of the railway track are brackets 9 having upper and lower inwardly directed bearings 10 in which are journaled the ends of vertically disposed spiral members 11 to which are fixedly connected gates 12 the latter normally disposed across the path of the track or track bed.

In the gap between the ends of the track rails 7 are disposed oppositely inclined displaceable rail sections 13, the inner ends of which intorfit each other and are pivoted as at 1 1 to form a hinge connection and the outer ends of the said rail sections 1.3 interfit the ends of the rails 7 and are pivoted as at 15 to form hinge connections with the same.

Immediately below the inner pivoted ends of the rail sections 13 is a bridge piece 16 the latter having its opposite ends provided with notches 17 to engage the spiral members 11 and thus cause the turning of the latter when the rail sections 13 are depressed by a train traveling over the said rail sections and upon the track. The said rail sections 13 are united by cross tie rods 18 which latter prevent lateral displacement of the sections upon the traveling of a train thcrcover.

At opposite sides of the bridge piece 16 and to the outside of the tracks are disposed guide rods 19 which latter are arranged in parallelism with the longitudinal sleepers and are fixed to the cross sleepers or beams 5 and slidably engaging these guide rods 19 are the ends 20 of upwardly bowed flat springs 21 which are in the form of plates and upon which latter the bridge piece 16 has its bearing. It is obvious that these springs 21 normally hold the inner pivoted ends of the displaceable rail sections 13 elevated.

Rising vertically from the supporting beam 8 and passing through suitable openings contained in the flat springs 21 and cross bridge piece 16 are pins 22, the latter having at their free ends nuts to form stops 23 in the path of the vertical movement of the bridge piece 16 so as to limit the said vertical movement thereof. Surrounding the pins 22 are vertically disposed coiled resetting springs 24 the latter having their upper ends bearing against the underface of the bowed springs 21 and their opposite ends bearing against the upper face of the supporting beam 8, and these resetting springs are adapted to act upon the parts to return the gates to their normal position across the track bed after being swung to a position to close a highway or road by the passage of a train over the displaceable track sections.

On the bridge piece 16 and surrounding the spiral members 11 are cuffs or collars 25 having square sockets 26 which normally receive squared portions 27 on the spiral members to maintain the gates from being accidentally pushed open from their position across the tracks.

WVhat is claimed is- 1. In a railway gate of the class described, a pair of normally elevated displaceable rail sections arranged in a railway track, a bridge piece upon which the rail sections rest guide rods disposed at opposite sides of the track and in parallelism therewith, vertically disposed brackets, rotary spiral members ournaled vertically in the brackets and actuated by the bridge piece, gates fixed to said spiral members, bowed spring members disposed immediately below the bridge piece and slidably engaging the guide rods, stop means for limiting the vertical movement of the bridge piece, and spring resetting means acting upon the bowed spring members.

2. In a railway gate, the combination with a railway track having a gap therein, of displaceable normally elevated rail sections pivotally connected at their inner ends and pivotally connected at their outer ends to the track, vertical brackets disposed at opposite sides of the track, vertically disposed spiral members journaled in said brackets, gates carried by said spiral members and normally intersecting the path of the track, bowed spring members, means supporting said bowed spring members to allow free movement of the opposite ends thereof, cross tie rods uniting the displaceable sections, a bridge piece arranged directly below the inner pivoted ends of the rail sections and having notches in opposite extremities thereof to engage the spiral members to actuate the same upon the lowering of the rail sections, and yieldable resetting means acting upon the bowed spring members to return the rail sections to normal elevated position.

3. In a railway gate, the combination with a railway track having a gap therein, of displaceable normally elevated rail sections pivotally connected at their inner ends and pivotally connected at their outer ends to the track, vertical brackets disposed at opposite sides of the track, vertically disposed spiral members journaled in said brackets, gates carried by said spiral members and normally intersecting the path of the track, bowed spring members, means supporting said bowed spring members to allow free movement of the opposite ends thereof, cross tie rods uniting the displaceable sections, a bridge piece arranged directly below the inner pivoted ends of the rail sections and having notches in opposite extremities thereof to engage the spiral members to actuate the same upon the lowering of the rail sections, yieldable resetting means acting upon the bowed spring members to return the rail sections to normal elevated position, and stop means for limiting the movement of the bridge piece in one direction.

In testimony whereof, I aflix my signature, in presence of two witnesses.

DOCK A. HALL.
