To all whom it may concern:

Be it known that l, CHARLES E. ENNIS, a citizen ofthe United States. residing at Trinidad, county of Las Animas, State of Colorado, have invented certain new and useful Improvements in Raibvaytlrosing Frogs of which the t'olhnving is a specification, reference being bad therein to the accompanying drawing. a

This invention relates'to a railway crossing frog and particularly to a structure embodymg a swing rail movable from alinentent with one track rail into alinemcnt with another at an angle thereto.

the invention has for an object to irovide a novel and improved construction of swinging frog rails and of means for locking them in shifted position which means are adapted to be operated by connections with an interlocking switch mechanism.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof detined by the appended claims.

In the drawing-"-Figure l is a plan of the invention applied; Fig. 2 is a vertical section of line of Fig. l; and Fig. 3 is a similar section of line 3- 3 of Fig. 1.

Like numerals of reference. refer to like parts in the several figures ot' the drawing.

The numeral 10 designates the bed plate of the crossing which is suitably supported and provided with extensions 11 disposed beneath the ends oi the lived rails 12. This bed plate. may be formed in sections it desired to facilitate storage and transportation thereof. The fixed rails 12 are secured to the bed plate by means of the angle bars 13, bolted to each of the parts in the usual man ner. 'l'hese plates are formed with an extended portion 14 adapted to lie beneath an end of the swing rails 15. 'l'hese'swing rails are mounted upon a circle plate 16 by means of the angle bars 17 bolted to each of the parts, while the circle plate is sur- .rouuded by an annular plate (37 bolted to. the

bed plate It} as shown in Fig. 2. The circle plate has secured thereto :1. depending bolt 18 passing through the bed plate It) and secured againstvertical movement thereon by a nut; 19.

For the purpose of moving the swing rails from the position shown by full lines in big. 1 to that' indicated by dotted lines therein, these rails have secured thereto Specification of Letters Patent. Application filed November 8, 1909.

brackets 20 from which pivoted links 21 extend to a lever bar 22 which is provided with a lateral arm 23 pivotally connected by links 24 to a shifting connection 25. These parts are similar at opposite ends of the bed plate and are connected to secure the necessary 0p iosite directions of operation by means o pit-men 26 extending to a ivoted lever 27 disposed centrally of the be plate. The shifting connection at one end is con nected to an operating rod 28 extending to an interlocking mechanism or other means for moving the parts.

For the purpose of locking the swing rails in their shifted positions, I have pro ided at each end thereof latch 'lretes 30 disposed upon the opposite sides of the rails and properly apcrtured at 31 cooperate with latch bolts movably mounted upon the bed plate. One set of these bolts is shown at each end of Fig. l and oomprises the bolts 32 ad: ted to enter a casin 33 within which one oi' the plates 30 carried by the swing rail travels when that rail is in alinement with the fixed rail. These bolts 32 are operated by means of crank levers 34 connected to a cross bar 35 which is provided at each end with crank levers 36 one of which is pivotally connected to the operating rod 31' for the bolts while the other is connected to the auxiliary operating rod 3b extending to the, opposite. end of the crossing. At: this end both the operating rod 3? and the auxiliary rod 38 are connected by crank levers 35) to the cross rod It) from which motion is transmitted by the crank lever 34 to the bolts 3:2 as before described. Both the operating rod 37 and the auxiliary rod :58 are pivotally connected to crank levers 4! which actuate the bolts 42 disposed in casings 43 upon the extensions It by which the swing rails may be secured in their shifted position as shown by dotted lilies in Fig. 1. I

l'lxtending between the operating rod 37 and toe auxiliary rod 38 is a cross bar 45 connected to each thereof by a pivoted crank lever 46. This bar has pivoted thereto a lever 47 having a bolt 48 operating in a casing 45) and also with a lever 50 having a bolt 51 operating in the said casing tolock the swing bars upon the bed plate when in shifted positions. The lever 50 is connected by a. lever 52 with the cross rod 45 before described. similar construction til (Fig. 3 m

is used at each side of the crossing. The 'oed plate is provided with a support 53 over which the inner ends of the swing rails lie when shifted to the dotted line position shown in Fig. 1.

At each side of the bed plate a latch casing 55 is secured thereto and has cooperatmounted therein. One of these bolts on each side is connected b a .lcver 5? to the operating rods 37 and 3t re spcctively, while the other bolt is provided with a similar lever 57 cmnxected by a link 58 to the rock lever 55) pivoted to the operating rods. The bolts 56 cooperate with the latch plates 30 carried by the swing rails to hold them in alinement as shown by full.

In the operation of the inventio: it will be seen that the swing rails of the crossing are held in full line position shown in Fig. l by the bolts 32 and 56. When it desired to swin the rails for alinelncnt with a cross' track, they are first released through the operating rod 37 and then shifted through the connection 28 to the dotted line posiiion shown in Fig. 1, after which the latch mechanism is again operated so that the bolts -12. 48 and 51 will respectively engage the latch plates 30 carried by the swing rails to hold them in shifted position so that the crossing is perfectly safe for the movement of a train at full speed thereover without jar or wear to any of the parts. The locking m chanism may be so connected as to open d d-ailing devices upon the tracks opposite to that with which die swing rails arc alinmi. This structure is mounted so that the swing rails may be readily shifted to prevent interferonce from snow or ice-and when in alinewant, are supported at their opposite ends. The operating parts of the mechani m here shown may be properly covered to prevent it from injury or inlerfenence under any conditions.

The invention presents a simple, -cllicicnt and economically constructed railway crossing frog adapted to be operated in connection with an interlocking plant or to be applied to an ordinary crossing conned ions.
