Application filed August 5, 1905. Serial No. 272,882.

To all whom it may concern;

Be it known that I, FRANKLIN H. SHAKES- PEARE, a citizen of the United States of America, residing in East Orange, in the county of Essex, State of New Jersey, have invented certain new and useful Improvements in Continuous-Rail Frogs and Switches, of which the following is a specification.

My invention relates to railroad-frogs, and particularly to that style known as movable-rail. frogs, in which a rail is moved transversely near the point of intersection of the rails of the diverging tracks, so as to form a continuous line of rails at such point. My invention is also applicable to switches having similarly-movable rails operated simultaneously with the rail of the frog.

The primary object of my invention is to produce the rails of the diverging tracks, whereby a continuous or unbroken rail bearing is pro-,

movement of the movable rails and to lock the same after perfect alinem'ent with the track over which the cars are to pass is attained, to obviate all necessity for the use of guard rails in connection with frogs or switches, to produce a frog or switch wherein the wearing parts can be cheaply renewed, and to produce a frog and switch in which the main parts are interchangeable with those of a frog and switch of different angle. The elimination of guard-rails, pointed frogs, and pointed switch-rails reduces the cost of construction. The general maintenance cost of railway connections and crossings will be reduced, due to the fact that with these frogs and switches it will not be necessary to keep on hand a supply of frogs of different angles for use in case of an emergency, for the main parts of these frogs and switches are interchangeable, since they are the same in shape and dimensions for varying angles of the frog, or, mother words, the main parts used in a frog of one angle may be interchanged with similar parts of a frog of a different angle or a simple, inexpensive, and substantial movable-rail frog with or without a movable-rail switch at the point ofintersection of joint of any two rails, and the same plate with those of a switch, and this is an im- I portant object of this invention.

A further object of my invention is to provide means for connecting the frog with the switch-operating mechanism and for moving and locking the same in position simultaneously with the operation of the switch from the switch-tower or elsewhere.

In the accompanying drawings, Figure 1 represents a plan view of the two intersecting rails of a frog embodying my invention. Fig. 2 represents an enlarged cross-section taken on the line 2 2 of Fig. 1. Fig. 3 represents a plan view of part of my invention, showing the arrangement of the switch-rails without the frog. Fig. 4 represents a central sectional elevation of the movable rail of the frog, showing the pivot about which the rail moves, taken on the line 4 4, Fig. 1; and Fig. 5 represents a diagrammatic view of the movable-rail switch and frog and the operating mechanism whereby they are moved simultaneously.

Referring to the drawings, especially to Fig. 1, in which the details of my invention as applied. to the frog are shown, the letters A and A denote the rails of a main track, and B the rails of a side track, and C the movable rails which in one position connect the parts of the rails A with the rails A and in another position connect with the siding-rails B.

As shown in the drawings, the rails A and B are arranged with their ends even and connected by bolts which pass through a wedgeshaped filler block U of the desired angle placed between the rails. The flanged splicebars or fish-plates W are placed on the outer side of each rail A and B, and the two plates extend beyond the ends of the rail substantially equal distances. C are placed between those extended ends of the splice-bars W which are connected by the curved bolts X, passing through holes in the end of the rail O, thereby limiting and guiding the movement of the rail and preventing longitudinal movement of the rails C. It will be noticed that these flanged splicebars are of the same style as those used at the or bar may be used on either side of the rail. It will also be seen that these bars extend to and are supported by the plate Z on the next tie, where they are firmly secured against lateral displacement.

The outer end of the rail C is supported on The ends of the rail 5 the plate Z, which has perforations or slots Z by which with the use of spikes it is secured to the tie. the segmental bolts X and the filler wedge or block U may have to be changed, but the plate Z remains the same in size and shape, although the angle may vary within certain limits. This plate Z may, however, be of a different shape and extend the entire length of the splice-bars W, thereby supporting the ends of the rails A and B and assuring equal level of the rails A, A, and B at the point of connection, or, if desired, the whole frog may be mounted on a plate, as indicated at Z, in the case of the switch, Fig. 3.

The mechanism for moving and locking the movable rails C consists of several distinct parts. Beginning with the rod K, which has preferably two diameters, the smaller of which passes through a hole in the web of the rail C, this rod is provided on each side of the opening or hole and next to the rail between the head and the base with flat bars or plates P P. O O are small wedgeshaped pieces on the outer sides of P P, through which the rod K also passes. As the rail 0 swings from one position to another the angle between the center line of the rod K and the center line of the rail C must vary by an amount equal to the frog angle. The rod K serves to move the rail C, and this variation of angle is taken care of by means of the wed eshaped pieces 0 O and the nuts M M on t e rod K, one of which abuts squarely against the Wedge-piece and holds the rail in alined position. The nutsM are adjustable, so as to hold the rail C in line with the rail A when the rod K is at the end of its stroke for any angle or width of rail. The nuts i are also adjustable to hold the rail C- in its other position in line with the rail B. these nuts M allowance should be made for lost motion in the stroke of the rod K, so that the plates P P and wedge-shaped pieces 0 0 will have sufficient play to permit the slight lengthwise motion necessary along the rail C as the angle between the rod K and rail C changes. On the opposite end of the rod K are the nuts J J, between which are helical springs S S. The sleeve H is fastened to the operating-rod L, Fig. 1, and separates the springs S S. The rod L continues to the side of the track and there connects with the rod or bar L, running along the track to the switch-tower and switch mechanism for operating the switch. By this bar the frog and switch are worked automatically on turning the switch-lever for one track or the other. Near the end of the rod L are studs Y, which pass through a slot in the plate G and serve, in combination with other means, to secure the plate to the rod. The locking means for the movable rail is also operated from the rod L. Fig. 2 shows a sectional view of the device by means of which the rail C is braced In varying the frog angle In the adjustment ofand kept in position after it has been brou ht into alinement with the rail intended. I denote circular rods or bars running along and fittin into a concave bar R, secured to the web 0% the rail, one being on each side of the rail 0. These bars I I are held in place by means of plates R, which are in turn held in place by bolts and nuts R Fig. 2. The plates R and R act as bearings for the bar I. Attached to orforming part of the bars I I are the locking-braces D D ,which serve to keep the rail in a locked position. Attached to or forming parts of the bars I I are the levers F F, which serve to turn the bar, and consequently raise or lower the locking-braces D D, as the case may be. E E are stationary brace-blocks secured to the tie or fixed by other means, one on each side of the movable rail, against which one of the braces D D bears when in locked position. The ends of the levers F F are bent as shown in Fig. 2 and are adapted to engage in the holes G of the plate G, which is moved laterally to and fro under the rail 0. These holes G are so placed and the ends of the levers F F are so bent that when the plate G is half-way between locked position the levers F F will have their bent ends in the holes G at equal distances from the rail C, and the braces D D, which are turned therewith by the rods I I, will hang equally on each side of the rail G, their ends being a little more than high enough to clear the top of the brace-blocks E E. These slots G are also cut wide enough to allow sufficient space for the ends of the levers F F to move without lateral motion of the levers F F relative to the plate G, caused by variations of the angle between the plate G and the rail 0. The tie on which the brace-blocks E E are fastened may be cut away, if necessary, to permit the sliding movement of the plate G and the levers F F. This plate G moves laterally with respect to the rail 0 and serves, through the levers F F, to operate the braces D D,.as before mentioned, in their positions against the brace-blocks E E, thus locking or unlocking the rail 0 before shifting to its other position, as the case may be. This device may be modified and strengthened by extending therod I and adding more bracerods D and brace-blocks E, as shown, on the movable rails of the switch in Fig. 3.

The central point about which the rail 0 of the frog turns may or may not be a pivot-pin. In Fig. 1 the pivot appears in dotted lines at the central point, and the rail is also shown supported by braces V, these being bent an amount equal to the frog angle and so placed as to support the rail 0 in both positions or for either track. These braces may be two 'or more in number, each bent or placed at the proper angle and mounted on a plate Z. The axial pivot-pin, which is also employed to prevent any longitudinal movement of the rail in connection with these braces or plates V, is constructed as shown in Fig. 4. A hole C is bored in the central part of the base of the rail C, extending partially through into the web. A hole of smaller diameter Z is bored into the plate Z at the corresponding point. A cylindrical pivot or pin Z of two diameters is then inserted by placing the smaller diameter in the hole Z and the rail C is placed so that the hole 0 is over the pivot Z. As the hole C is preferably bored entirely through the rail-base, there will be a small hole on each side of the web, whereby oil may be introduced around the pivotpin.

As before stated, the mechanism for operating the movable rails of the switch is almost identical with that for moving the rail of the frog, and both rails are operated by the rods L, attached to the main switch-rod L, so that one cannot be operated without the other, as shown in Fig. 5.

The rod L is attached to one arm of a bellcrank lever L secured to an adjustablymovable block L at the end of the tie. In the other arm of the bell-crank lever is a slot L, as shown in Fig. 3, through which passes a pin in the end of the rod L. By changing the position of the block L the distance between the corresponding bell-crank center and the center line of its rod L is varied, thus varying the throw of the rod L.

tact with the spring S.

The operation of my device is as follows: Assuming the switch to be in the position shown in Fig. 3 and the frog as in Fig. 1, the rods L, which are all connected with the switchrod L, are moved in the direction of the rail B through the bell-crank levers. The movement of the rod L causes the sleeve H to slide along the rod K, thus releasing the spring S and bringing the sleeve H into con- In the meantime the rod L has moved the plate G to its mid- -way position in respect to the rail C and through the lever F has raised the brace-bar D into a position high enough to clear the brace-block E and through the lever F lowered the brace-bar D only so far as to still clear the top of the brace-block E. The rail 0 is now free to move over into position in line with the rail B. The rod L continues to move. The spring S is so designed that the force necessary to cause its compression is in excess of that necessary to move the rail C from one positionto the other. The movement of the rod L is transmitted, through the sleeve H, spring S, and the nuts J, to the rod K. The nut M then moves away from the wedge O, and the nuts M come into contact with the wedge 0. Motion is thereby trans mitted to the rail C, which moves over into position in alinement with the rail B, at which point the nuts M come squarely into contact with the wedge-piece O and serve to press the rail C firmly over against the splicebars W, extending along the outside of {Ithe rail B. As the rod K cannot now move any farther in the same direction, a further movement of the rod L serves to compress the spring S and move the plate G laterally with respect to the rail 0, thus lowering the bracebar D into position against the brace-block E, and thereby locking the rail C in position of alinement.

From this description it will be seen that most of the parts are interchangeable with the parts of other switches and frogs for any degree of angle. with very slight alterations the device can be applied to three intersecting rails, as well as to the entrance of a third-rail switch, by applying the device to the rails of all three tracks at the point of entrance.
