located outside of the main track rails. A feathered switch piece 6 is pivoted as at 7 to the switch rail 3, and its free end is adapted when it is in closed position to abut against the inner side of the main track rail 1.

bridge switch piece 8 is pivoted as at 9 to the switch rail 5, and is provided with a head flange 8, as most clearly shown in Figure 7 which is adapted to overlie the main track rail 2 when this switch piece is in closed position. The switch pieces 6 and 8 are connected together by a bar 10 through the medium of which they can be moved into closed or opened position and secured in either one of such positions. 'The switch bar 10 is connected to the switch pieces ,6 and 8 by lugs 11 carried by the switch pieces, brackets 12 secured to the switch bar and provided with openings i or the reception of the lugs, and bolts 13 which pivotally connect the lugs to the brackets.

A frog 1 1, which is adapted to be mounted upon either of the main rails 1 and 2 so as to permit the switch'to be arranged at either side oi the main track, is of elongated rectangularlormation and provided in its under side with main track rail receiving grooves 15 and 16. The grooves 15 and 16 intersect and are arranged at an angle to the longitudinal median line of the frog 14. The groove 15 permits the frog 14L to be mounted upon the main track rail 2 when the switch is arranged as shown in Figure 1, and the groove 16 permits the frog to be mounted upon the main track rail 1 when the switch is to be arranged at the opposite side of the main track. Due to the angular an rangement or the grooves 15 and 16 with respect to its longitudinal median line, the frog 14 occupies an angular position with respect to the main track rail upon which it 1s mounted.

The frog 1 1 is provided at its ends with dove-tail extensions 17 one of which contacts with the inner side and the other with the outer side-of the web. of the main track rail upon which the frog is mounted. To permit them to pass beneath and contact with the under sides of the head 01 the main track rail upon which the frog is mounted, the extensions 17 are offset downwardly from the upper side of the frog. The frog 14, is secured in place by the eX- tensions 17 and set screws 18 which latter have threaded en agement with the frog and engage the web of the main track rail and webs of the switch rails and t. i

In its upper side, the frog 14 is provided with wheel flange receiving grooves 19 and which intersect and are arranged at an angle to the longitudinal median line of the frog. The groove 19 alines with the inner sides of the heads of the switch rails 3 and 4, and the groove 20 alines with the inner sides of the heads of the main track rails 2. The frog 14 is provided at its upper side and in alinement with the grooves 19 and 20 with depressed seats 21, 22, 23 and 24 the purpose will presently appear.

The uppersides of the switch rails 3, 4 and 5 and main track rails 1 and 2 are located in the same horizontal plane, and the upper side of the frog 14 occupies a plane located above the rails. Bridge rails 25 and 26 overlie the main track rails 2 and are secured thereto and to the frog 14. A bridge 27 overlies the switch rail 3 and a bridge rail 28 overlies the switch rail 4, and are secured to these switch rails and to the frog 14. The bridge rails 25, 26, 27 and 28 incline upwardly in the direction 01 the frog 14, and are of similar formation in cross section, each having a head 29 overlying the main track rails and switch rails and having their adjacent ends positioned on the seats 21, 22, 23 and 24 ot the frog 14. The adjacent ends of the heads 29 are provided with dowel pins 30 fitting in openings 31 in the seats of the frog 14. The bridge rails 25, 26, 27 and 28 also have vertical portions or webs 32 which contact with the sides of the heads of the main track and switch rails, and ribs or base flanges 33 which contact with the webs of the main track and switch rails. The bridge rails 25, 26, 27 and 28 are secured to the main track and switch rails and frog 14 by bolts 34. The bridge rails 25 and 26 carry the train over the frog 14 when the switch is opened, and the bridge switch piece 3 bridge rails 27 and 28, and frog 14, carry the train over the main track rail 2 when the switch is closed.

The temporary installation (it the switch has been described and is illustrated in the drawings. When it is desired to effect a permanentinstallation oi the switch, the bridge rails 25, 26, 27 and 28 are omitted and the frog 14 is inserted in one oi the main track rails 'l and 2 in inverted position to present the grooves 15 and 16 uppermost "for the reception of the wheel flanges o1 the train. To permit of this installation of the frog 14, one of the main track rails 1 and 2 is cut away for the reception of the frog and the frog is secured to the main track rail sections by the extensions 17 and bolts 18. In this installation of the switch, one of the grooves 15 and 16 will register with the inner sides of the heads of the switch rails 3 and 4 and the other with the inner side of the head of the main track rail to which the frog 14 is secured.

From the foregoing and accompanying drawings, it will be seen that the switch embodies a construction which will enable it to be installed at either side of the main track and which will enable it to be in stalled permanently or temporarily. The frog 14 may be readily and firmly secured upon one of the main track rails when it is desired to effect the temporary installation of the switch or within a cut out portion of one of the main track rails when it is desired to effect the permanent installation of the switch. The manner in which the bridge rails 25, 26, 27 and 28 are secured to the frog l4 and to the main track and switch rails prevents them from having any relative movement with respect to the parts to which they are secured. The frog 14 is held against vertical movement with respect to the main track rail and switch rails to which it is secured by means of its extensions 17 which in addition to contacting with the under sides of the heads of these rails also contact with the base flanges and webs thereof.

The ties are especially adapted for supporting the switch rails and the main track rails at the point of installationof the switch. Each of these ties is provided adjacent its ends with upper recesses 36 for the reception of the rail bases and rail clamps 37. The tie is provided with flanges 38 and the clamps 3'7 with flanges 39 which contact with the rail bases. The clamps 37 are provided with side portions 40 of reduced thickness which occupy horizontal grooves 41 formed in the tie 35 and communicating with the recesses 36. The vertical walls of the grooves 41' and the adjacent vertical edges of the clamp portions 40 are inclined transversely of the tie 35, and the clamp portions 40 are provided with slots 42 which are arranged in parallel relation to said inclined walls and. Bolts 43 pass through the tie35 and slots 42 to secure the clamps 37 to the tie. The manner in which the clamps 37 are securet to the tie 35 is such that they move in the direction of the rails when driven transversely in one direction with respect to the tie and such that they move away from the rails when they are driven trz'msverscly in the opposite direction with respect to the tie. It will thus be seen that the rails can be readily and firmly secured to the tie and readily released therefrom. The clamps 37 are held in rail. retaining position by bolts 44 which pass through openings 45 in the clamps and openings 46 in the tie To permit the clamps 37 to be swung tree of the rails, the vertical walls of the grooves 41 h zrve portions thereof inclined as shown at 4 It should be understood that the drawings are merely illustrative and do not pretend Ill) to give exact proportions. Furthermore, the said drawings are illustrative of a pre ferred construction, it being my expectation that v rious changes and modifications may be made without departing from the spirit and scope of my invention.
