RAILWAY SWITCH.

Application filed August 25, 1926. Serial No. 131,347.

The present invention relates to fittings for railway switches having special features which make them particularly well adapted to that type known in the art as slip switches and movable point frogs.

Among the objects of the invention is a construction in which the switch points are more strongly reinforced and maintained against displacement than in the present constructions.

Another object is the provision of means by which adjustments for wear, and fit may be more easily and efliciently made.

A third object is to provide a switch bar that will better resist the rolling or turning of a switch point away from the stock rail.

And a fourth object is to provide a switch circuit controller that will detect any such rolling action of the switch points.

Other objects will readily occur to those skilled in the art upon reference to the fol lowing description and accompanying drawings, in which- Fig. 1 is a plan view of a rail, switch point and the attached parts;

Fig. 2 is a side elevation of the same;

Fig. 3 is an end view of the same with the rail in section;

Fig. 1 is a section on line 4% of Fig. 2;

Figs. 5, 6 and 7 are perspective views of certain details,

In the drawings a conventional rail and switch point are shown at 10 and 11 respectively as carried upon ties, one of which is shown at 12, with the usual tie plate shown at 13. As is customary, the point 11 is formed of a rail having its head planed tapering to a point and having one side of its flange planed so that it will rest upon 4 the flange of rail 10 when the point 11 is in the position shown in Fig. 3, for example.

On account of the small section of the end portion of switch point 11, it is necessary that it does not extend substantially beyond the tie plate. The switch point is therefore provided with an extension in the form of a reinforcing plate 15, which extension permits the attachment of the switch bar or tie rod 16 beyond the point.

The reinforcing plate and double half hearing clip 15 consists of a flat upright plate adapted to fit on the web on top of the base portion of the point 11 and has its lower edge provided with an inclined flange 20. Near the ends of the plate are formed two vertically arranged half bearings 21 and immediately below the bearings the flange 20 is extended as at 22 to form a rest for the switch bar. This plate 15 is bolted securely to the point 11, with a port-ion extending beyond the latter, which portion carries one of the half bearings 21.

The switch bar or tie rod 16 in the present construction consists of a bar extending across the track below the rail lever and has its ends turned up as at 25 with a round vertically arranged bearing end 26 offset from the part 25 so that a shoulder 27 is formed directly below the bearing part 26.

The bar 16 is of such length that the end 26.

fits into half-bearing 21 with the shoulder 27 resting upon the flange extension 22 which in turn rests upon the flange of point 11. When the bar end is in place the bearmg cap 30 (see Fig. 7) is bolted on. As shown, the cap 30 is provided with pilot lugs 31 adapted to cooperate with corresponding notches 32 in the half bearings 21 to maintain the alignment of the parts 21 and 30 of the bearing. As shown most clearly in Figs. 3 and 4, the lugs 31 and notches 32 are preferably provided with their upper sides inclined to provide a cam action to force the cap 30 downwardly when the parts are bolted together and the bearing parts are so made that their initial adjust-- ment provides for taking up for wear.

One of the features of this construction is that the bolts 33 and nuts 34:, securing the bearing cap 30, together with the inclined contacting surfaces of flanges 22 of member 15, the flange of the switch point, and shoulder 27 on tie rod 16, furnish means for adjusting the vertical bearings 26 both horizontally and vertically. Moving the bearing cap 30 toward the switch point 11 by means of the bolts 33 and nuts 34 forces the shoulder 27 up on the flange 22 and the latter up on the point flange while the horizontal looseness in bearing 26 is being taken up. Obviously, loosenin the units 34 will produce a corresponding loosening both vertically and horizontally,

As indicated in Fig. 1, the half bearing 21 may be a separate piece from the plate 15 and in this figure the part 21 indicates such a separate part.

In Fig. 4: also is shown the connection of a circuit controller connection bar 4:0 which consists of a suitable bar having its end bent up and having an eye 41 which may be secured to the back of plate 15 by one of the bolts serving to hold the hearing together.

Fig. 5 shows a plate 15 having only, one bearing half 21 for use where the.

struction that more strongly resists the tend- I ency for the point to roll or turn from the rail '10. Another advantage is that the plates 15 (Fig. 6) are universal and may be used on either point merely by reversing Having now describedthe invention and 111g a flange, a reinforcing plate, also flanged,

the preferred form of embodiment thereof, it is to be understood that the said invention is not to be limitedto the specific de tails herein described and illustrated but only by the scope of the claims which follow.

I claim 1. In a railway switch, a switch point provlded with a reinforcing plate extending beyond the tip of said point, a vertically by said plate, atie rod formed with a vertical bearing end adapted to operate in the plate carriedbearing and provided with a slopin shoulder beneath .said bearing end, said shoulder adapted to rest on said sloping flangewhen the bearing parts are in operating relation, and a bearing cap adapted to "be secured to said plate over the said hearing end of the tie rod.

3. In a railway switch having a switch point, a tie rod, and a vertically arranged bearing for one end ofithe latter carried by said point, means for simultaneously adjusting said bearing vertically and horizontally.

it. In a railway switch, a switch point havand adapted to be secured to the web of said point and to be supported upon the point flange, and a tie rod having a vertical bearing connection with said plate and adapted to rest upon the flange thereof.

5. In a railway switch, a switch'point havinga flange, a reinforcing plate, also flanged,

and adapted to be secured to the web of said point and to be supported upon the point flange, said flanges sloping away from the said Web, and a'tie rod having a vertical bearing connection with-said plateand having a sloping shoulder adapted to rest upon the flange of said plate whereby movement of said rod horizontally towardsaid point also causes it to move upward.
