.To all 'whom't't may concern: I 4 4 Be it known that I, JosnPH A. Oorrocx, a citizen of the United States, residing at Pinehurst, in the county f Dooley and State ofGeorgia, have invented a new and useful Improvement in Railway-Switches, of which the following is a specification.

This inventionrelates to railway switches and particularly to that class thereof in which thepoints lap I preferably integral with the point.

The cross-over or frog points D and-E are each in V rail.

the head of the main rails on top, whereby the use of frogs or breaks in the main track is avoided, so that the danger incident thereto is eliminated, the track when the, switchis open being continuous as to both rails -and the points being so .constru'ctedlas to lift the wheels to cause the flanges thereof to clearthe main.

tracks when the train is taking the switch.

The invention is illustratedin the accompanying drawings, in which 7 p 'Figure 1 is a plan view of the switch, open, Fig.2 is a plan view of the same, closed. Figs. 3, 4, and 5 are side Views of the various points.

-' Referringto the drawings, A indicate the continuous main line rails, and A the side track rails. The outside switch {joint B closes against the side of the main rail; andhas an incline B (see 'Fig. 5) of sufficient height to raise the wheel flange "above the head of the The inside switch point C, has a knife edge at Q which closes against the side of the main rail, and also an incline C corresponding to the incline B, to

keep the trucks level. Said point alsofhas an'inside guard 0 forming a groove for the wheel flange, espe cially so that the exit of a' track from the side truck will be guided safely to the niain line rail. This guard is clined or elevated so that when the switch is closed the heads thereof will overlie the head of the rail A, and swing to contact with a scarf or beveled joint there- 'over, forming a continuous cross-over rail of sufficient height to carry the wheelflanges over the main rail. These points are slightly different in shape, the inside point D having a slightly greater length and curve or splay than its fellow E, to bring the latter well out of "he way of the flange of" :a wheel on the main track,

, neath the rail, said bar being but when the switch is closed they meet over the track, asstated.

Suitable bed plates are provided on the ties for the points to slide on, and also, the point D has a bar d which slides in a groove f formed in the top of the frog plate F, under the rail A', which thereby serves to can work thereunder. 'The shaft has cranks 7 connected by rods 8 to the respective points, the throw of the respective cranks being appropriate to the desired movement of the points; and the respective points are;

connected to the various rails by the usual loose bolts and bars. v

'The point 13 extends a sufficient distance in advance of the point 0 to raise the wheel on its incline enough to clear the flange over the rail before the truck is shifted toward the side traek.

It will be seen that when the switch is open the main track is entirely clear, without break or frog, and free from the dangerous features incident thereto,

1. A railway switch having a pair of, ci'oss over'polhts located on opposite sides of the rail head, the-heads of said points being raised'ahd extended to close over the rail head, a plate, under the railand points, having a groove extending across under the rail, and :1 bar fixed to one of the points and slidable in the groove, undersaid rail.

2. A railway switch having" a pair of cr'ossover points I located on opposite sides of the rail head, the heads of said points being raised and extended to closeovr the raiI head, a bar fixed to one of the points, and 'extendinighe slldable thereunder for the purpose set forth. JOSEPH coPPocx.
