Specification of Letters Patent.

Patented July 21, 1908 To all whom it may concern."

Be it known that I, Ji nns L. BAILEY, a citizen of the United States, and a resident of St. Augustine, in the county of St. John and State of Florida, have invented a new and Im roved Switch, of which the following is a. ful clear, and exact description. i

This invention relates to switches, and more articularly to railroad switches having moveu 1e switch points, and a swinging switch rail or frog.

An object of the invention is to provide a simple, strong and efhc1ent switch lor use in connection with railway lines and the like,

which has movable switch points, and a swinging switch rail or frog which can be locked in a plurality of positions, from the switch stend.

A further object of the invention is to arovide a switch of the class described, in w rich the swinging rail or frog can be operated from the switch stand, and at the same time locked in a plurality of positions from the switch stand.

A still further object of the invention is to provide a switch of the class described in which the swinging rail or frog is locked or clamped in position to avoid pounding, hammering and excessive wear when a train is.

passing over the switch.

Another object of the invention is to provide a switch of the class describedwhich includes a dereiling device operable from the prevent rolling stockfrom passing from a siding over the switch, when the letter is closed, that is, when the switch is arranged to permit a train to move along the main track without passing on to the siding.

The invention consists in the construction and combination of parts to be more fully particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this s ecification,

' inwhich similar characters ofre erence indicate corresponding parts in all the views, and in which Figure 1 is e plan view of the switch of my invention, showing the swinging rail or frog in different ositions in full and dottedlines Fig. 2 is an enlarged plan view of a portion of the switch showing 1n detail the swinging rail or frog; Fig. 3 is an enlarged side elevation sh0w ing one end of the swinging. rail or frog; Fig.

Fig: 11 IS :1 Ian view showing the derailing device and t e mechanism for operating the same.

Before proceeding to a. more detailed explanation of my invention it should he clearly understood thzit when the term "closed is used with reference to the switch, it is intended to signify thereby that the switch is so arranged that e train can travel along the main track without entering the siding. When the term open is used with reference to the switch it is ineant thet the switch is so .arranged that a train will pass from the main track to the siding, and from the siding to the main track. The dereiling device which I employ is of service 'in. preventing rolling stock from accidentally passing from the siding to the ms-int'rsck when the switch is closed, and thereby doing in'ury to the swinging rail or frog. When t e switch is open, the dersiling device must of course be inoperative, and to avoid the necessity for specially operating the dersiling mechanism 1 provide means for, actuating it from the switch stand itself.

My invention resides, primarily, in the arrangeinent of the swinging rail, the provi sion of the derailing device, the construction and the arrangement of the lnechenisinfor simultaneously throwing and locking the frog and operating the derailing device, endin the arrangement of the details of construction to carry outthis particular purpose.

Referring more particularly to the drawings, 12-12'-represent the usual cross-ties or sleepers of wood or any other suitable material. The track and other rails are secured to the ties in any preferred or common manner, for example, as is ordinarily done, by

The outer msin'tmck'rsil l 3 is continuous, while the inner main track rail 14 has a gap in which is arranged a, swinging rail or frog 15, as will appear more clearly hereinafter. The switchv oint 16 is located between the main track rails and has one end I carried by a chair-17 which also supports the innermein rail 14st one end 0 the gap.

end of the inner siding rail 21. siding rail 22 merges with 16 by means of the usual cross rods 19.

The inner main rail is formed into a further switch point 18 joined rigidly with the point A chair 20 similar to the chair 17 carries the end of the main rail at the end of the gap opposite to the chair 17, and similarly carries the The outer the inner main rail 14 in the-usual manner. The switch points 16 and 18 are operated from the switch stand 23 by means of a suitable connecting mechanism 24 in the usual manner. The switch stand is mounted upon certain extended ties, and comprises a base 25 having a target standard 26, a locking lever 27 and a ground weight lever 28. The latter, at the end, has the usual weight'29. The levers 27 and 28 are ivoted upon a pin or shank 30 extend ng aterally from the switch stand.

A base 31 fashioned from cast iron or other suitable material is mounted upon a tie 12 near the center of the gap in the inner main rail 14. The base 31 has an upwardly disposed seat 32 preferably-of circular crosssectionand formed to receive a correspondingly formed socket 33. The seat and the socket have registering openings therethrough in which is arranged a pivot bolt 34 having its head 35 countersunk in a suitably extended portion of the opening in the socket. A nut 36 serves to secure the bolt in position and the parts together] The base 31 is laterally extended and is secured to the tie by means of bolts, rivets or spikes, or in any other convenient manner. The socket 33 has formed upon the upper face thereof, railclamps37 by means of which the swinging rail or frog is secured to the socket.

. Bolts 38 arranged in suitable registering openings of the clam s and the frog serve to secure the latter fir y in place. The socket embraces the seat at the sides thereof and has its lower rim resting upon the base,

thereby pfeventing dirt or other material from wor ing its way between the bearing surfaces.

At each end of the frog 15 are mounted brackets 39 having clam ing members 40 arjranged at each side of t e frog, and secured in position by means of bolts 41. The brackets 39 have shelf extensions 42 projecting underneath the chairs 17 and 20. The latter, at the upper faces have rail clamps 43 arranged to engage at each side of the ends of bolts 44 located in registerin openings of the clamps and the rails, to ho d the .latter in position. The

and attached to a rod 47.

chairs are spiked or otherwise firmly secured .to the ties which carry them.

' Each of the shelf extensions 42 has bearings 45 in which is movably' mounted a pin- The latter has one end bifurcated Each of the'lat- .ter has pivoted at one enda bell crank lever 48 mounted upon a support 49 carried by certain of the ties. adjacent to the switch stand has the armremote from the arm connected with the rod 47, joined by means of a throw rod 50 with the end of the ground weight lever 28. The same arm of the bell crank lever 48 is connected by means of a link 51 with the arm of the other bell crank lever remote from the other rod 47. Each of the pintles 46 between the bearings 45 has a cam locking member 52 rigid therewith. When the ground weight lever 28 israis'ed, the rod 50 is operated to swing the'bell crank levers 48, and these, in turn, by means of the rods 47, swing the frog upon its ivoting base. In this way, the frog can e disposed to close or open the switch. The arrangement is such that when the ground weight lever is actuated to operate the frog it at the same time correspondingly operates the switch points 16 and 18 through the connecting mechanism 24.

Each of the rods 47 has an opening 53 in which is loosely arranged the end. 54 of an arm 55. The latter has its opposite end pivoted in a slot 56 of a lock rod 57. The latter switch stand. When the lever 27 is swung in one direction or the other, the lockrod is correspondingly actuated, and serves to rotate the rods 47 by means of the arms 55. The

rotation of the rods 47 correspondingly swings the cam locking members 52 into position between lugs 58 formed at the under sides of the chairs 17 and 20, or out from between the lugs. 'It will be understood that when the locking members are operatively arranged, the frame is-locked in position andcannot be displaced from that position withof the lever 27 and the intermediate con necting parts.

The locking members 52 are preferably The bell crank lever 48 is pivoted to the end of the lever 27 of the out releasing the locking members by means nearly circular in form and are eccentrically mounted upon the pintles 46.v Each of them has a portion cut away to form a key-way, so when the locking members are disposed in certain positions they can pass underneath the lugs to permit the frog to be operated.

When the locking members are swung into a locking position, they engage, furthermore,

at the under side of the chairs and effect a cam-like action which draws the ends of the frog firmly into position upon the chairs. In

this way the frog is securelylocked in position, and rattling and hammering of the same is obviated together with the wear of the parts, incident thereto.

Anypreferred or common form of derailing device can be used in connection with my switch. The derailing device shown in Fig.

11 is merely used as an example, and includes a derailing rail 59 integral with the outer siding rail 22, and outwardly disposed,

so that when the derailing point 60 is out of engagen ent'with the rail 22, a .car, in travelsea-e70 mg along the siding will be displaced from the falls by the rail 59. A support 61 is carified hy,ties b2 and has pivotally mounted thereupon a bell crank 'lev'erl62, connected by means of a rod 63, with a bell crank lever 48. A link 64 connects the bell crank lever 62 with the derailing point 60. The arrangement is such that when the switch is into contact with the frog to displace or oth- When the switch stand is 'erwise injure it. operated to open the switch,.the derailing device is simultaneously o erated through the rod .63, the bell crank ever 62 and the link 64, so that the derailing point 60 is lock rod 57.

.swung inward against the rail 22 to'permit a car to pass fiom the siding to the main track without derailment.

To enable the rods 47 to turn freely, they pivoted heads 50" by means of which the rods are connected to the bell crank levers 48. Between the switch stand and the rods 47, the rod 50 and the lock rod 57 have joints 51 and 57 respectively, to permit the full rods 47 transversely of the rod 50 and the Having thus described myv invention, I claim as new, and desire to secure by Letters Patent:
