RAILWAY-SWITCH.

Specification of Letters Patent.

Patented July 25, 1916.

To all LU/00m it mag concern:

Be it known that I, RAY W. DAVrs, a citizen of the United States, residing at Brownsville, in the county of Fayette and State of Pennsylvania, have invented new and useful Improvements in Railway- Switches of which the following is a specification.

The present invention relates to improvements in railway switches and the primary object of the invention is to produce a device of this character which will provide a positive guide for the wheels of the rolling stock and obviate the shock and jar usually incident to the wheels of a train passing over a switch and frog.

Another object of the invention is to produce a device of this character whereby the employment of guard rails is not required and the dangers of derailment frequently occasioned by the springing or loosening of the guard rail, entirely obviated.

A still. further object is to provide a single switch point arranged between two main rails, and provided with means whereby the same may be thrown in locked engagement with either of said rails.

The invent-ion further consists in the con structiom combination and arrangement of parts set forth in the following specification and falling within the scope of the ap pended claims.

In the drawings: Figure 1 is a plan view of a switch constructedin accordance with the present invention, Fig. 2 is a transverse sectional view on the line 2'2 of Fig. 1, Fig. 3 is a similar sectional view on the line of Fig. 1, Fig. 4 is an enlarged detail sectional view approximately on the line i lof Fig. 1, Fig. 5 is a sectional view approximately on the line. 55 of Fig. 4, Fig. 6 is a side elevation of the frog and the switch point attached thereto, Fig. 7 is a similar view looking toward the opposite side of the frog and switch point, Fig. Sis a detail perspective view'of one of the sections comprising the pin supporting member, Fig.9 is a perspective view of the pin, Fig. 10 is a perspective view of one of the bearing plates for the tie, Fig. 11 is a perspective view of the locking rod, Fig. 12 is a side elevation of a modified form of frog and means for connecting the switch point to the frog, Fig. 13 is a perspective view of the frog, Fig. 14 is a perspective view of the switch point, Fig. 15 is a perspective view of the spring connecting plate between the frog and switch point provided with U shaped lateral extensions forming stops, Fig. 16 is a plan view of a switch constructed in accordance with my invention provided with a trailing rail, and'Fig. 17 is a side elevation of the trailing rail connected with the switch point. F ig. 18 is a detail perspective view of the mechanism employed for-operating the switch points and the locking rod.

In the drawings the numeral 1 designates two straight rails of a track.

Alining with the rails 1 are angular-1y disposed rails 2. A frog 3 is disposed centrally or intermediate of the angular rails 2 and a switch point 4 is connected with the frog and normally lies centrally between the rails of the track, in a position to be thrown into contact with either of the angular rails 2at their points of abutment with the main rails 1. Rails 5 are secured or arranged parallel with the angular sides of the frog 3, and the rails 5 are each arranged in proper spaced parallel alinement with the respective rails 2, so that the track between one of the rails 2' and one of the rails 5 is a continuation of the main track, and the track providedbythe second rail 2 and the second rail 5 may be considered a side track.

The numerals 6 indicate the ties upon which the rails rest. ranged upon their upper faces metal wear or hearing plates 7, and the plates 7 which underlie'the switch point have centrally arranged longitudinally extending ribs or enlargements 8.

The ribs 8 permit of the shanks of wood screws 9 contacting with the longitudinal edges of the plates 7, after the said screws have been driven in the ties 6, and also arranging the heads of the wood screws'over the plates below the ribsso as not to interfere with the free movement of the switch point 4. The plates between the rails 1 and the. angular railshave attached thereto or These ties have an integrally formed therewith upstanding flanges or brackets effectively support or provide abutments for the switch point to prevent the tilting of the same by the pressure of the flanges of the wheels of the rolling stock thereon. All of the plates, at the switch, are provided with brackets 11 which engage with the outer faces of the rails, and the plates upon the ties which support the frog rails 5 have brackets 12 arranged thereon which may contact with both the inner and outer faces of the said rails.

The frog may be formed from two angular members, as shown in Fig. 1 of the drawings, one of the said members having a tongue 13 that is received within a groove 14 upon the opposite and co-acting member. The frog, as well as the heel of the switch, rests upon a flat plate 15 which is secured to the ties and the ties may be provided with depressions to receive the plate to allow the plate to lie flush with the upper faces of the ties.

Arranged upon the opposite sides of the frog, between the head and base flange thereof, are spring bars 16, said bars having inwardly extending portions or tongues which contactwith the opposite faces of the web of the switch point and extend a sufficient distance from the frog to normally sustain the point 4 centrally between the rails 1.

' tending portions 21 which "are adapted to The spring bars are connected to both the point and to the frog through the medium of bolts 17, and the tongues of the springs which lie against the opposite sides of the frog are provided with elongated openings 18 which are partially covered by the heads of the bolts 17. I

If desired, one of the plates 16 may be rigidly secured to one side of the frog, its end or portion engaging with the point having elongated openings which are partially closed by the heads of the securing bolts, while the second bar is rigidly secured to the opposite face of the switch point and movably connected with the opposite faces of thefrog, (see Fig. 7). Secured to the opposite sides of'the switch point, at a suitable distance from the end thereof, are the elongated head portions 19 of a pin supporting member. The pin supporting member comprises two similar sections, having reduced sides or stems 20 which depend centrally from their heads 19 and are arranged 1 in suitable openings or notches in the base flange of the frog point. The sides 20 are provided with semi-circular inwardly exabut to provide the member with a collar or sleeve 26 and the upper edges of the said sleeve areformed with alining notches providing pockets 22 for laterally extending,

arms 23 provided upon the upper end or head of a pin 24. The outer ends of laterally extending arms 23 are provided with flanges I 25 which are adapted to abut With the P posite sides of the collar formed by the members 21, and the slots or depressions in the upper portions of said members are of a combined width to agree with that of the arms 28. The sleeve 26 has its pockets 22 covered by plates 27 which are integrally formed upon the upper inner faces of the sides 20 of the heads 19 and which serve as a top for the socket of the sleeve. Arranged within the sleeve 26 and surrounding the pin 24 is a washer 28, and the pin projects a suitable distance below the sleeve and below the washer and is adapted to be re depression 33 formed in the upper face of the tie upon which the said plate is arranged. The plate as well as the connecting member 82 of the yoke are provided with registering openings through which pass a pin 34 that pivotally secures the bar 30 to'the tie. The bar 30 between its pivot 84 and its elongated opening 29 is provided with a plurality of spaced openings 35 any one of which being adapted to receive a pivot pin 36 which passes through one of the bifurcated ends of the link 37. The opposite end of the link 37 is also bifurcated and is provided with openings for the reception ofa pivot pin 38 which also passes through one of a plurality of openings provided in the offset end'40 of a bent lever 41. The end 40 of the lever is received within the yoke of the plate 7 and is pivposition with relation to the longitudinal arm of the said lever. The rod has its free end preferably offset and provided with an.

eye or opening 47 through which passes a pin 48 formed upon one end of a lever arm 49. This lever arm is connected with the operatingrnember or throw arm 50 provided upon a switch stand 51,:

It should be stated that the pin 24 is provided with an elongated slot 52, through which is passed a key in the nature of a cotter pin 53, the said pin being arranged below the bar 30 and the said bar engaging the u-nderface of the sleeve sustains the washer 28 within the sleeve 26. By swinging the throw arm in one direction, it will be noted that the switch point will be forced toward either of the rails 1 to open either the main or the side line, and the said switch point bearing upon the ribs 8 of the plates 7 will be afforded a free movement in either direction, while the brackets 11 contacting with the sides of the said switch point effectively prevent the turning of the said point and brace the same when engaged by the wheels of the rolling stock.

It is desirable that the switch be locked in either of its swung positions, and to accomplish this I provide a locking member in the nature of a rod or bar 56 which has its opposite ends reduced and received in boxes 57 which are secured to the base of the outer main rails by bolts or rivets passing through the flanges of the said main rails. The rod 56 is provided with diametrically opposite lugs 58 and 59 respectively, the inner or opposite edges of the said lugs being angular, as indicated by the numerals 60 and 61 respectively, and normally the lugs 58 and 59 are sustained in a horizontal position and out of contact with the switch point. One of the reduced ends of the rod is extended beyond its bearing box and is provided with an angular portion or arm 62 which terminates in a finger 62 and this finger is rotated by the throw arm 50. By such an arrangement it will be noted that the throw arm is operated to swing the switch point before the member 56 is rotated to bring either of its lugs 58 or 59 into contacting engagement with the switch point, and further that by providing the lugs 58 and 59 with the angular faces 60 and 61 respectively, the said switch point may ride over the lugs, should the member 56 be prematurely turned. A

satisfactory mechanism for operating the,

switch points and the locking rod 56 is shown in Fig. 18 of the drawings. The throw arm 50 is secured to a shaft a, which extends laterally through the switch stand 51 and which has its end provided with a mutilated gear wheel 5. The wheel i) meshes with a toothed wheel 0 and the said wheel 0 meshes with a similar toothed wheel (Z having a shaft connected with the finger 62 of the member 56. Secured upon the shaft a is a mutilated beveled tooth wheel 0 that is engaged by a beveled tooth wheel 9 arranged upon a vertical shaft 00 mounted in suitable hearings in the switch stand, and to this shaft :0 is secured the lever arm or link 4,-9 that is connected to the rocker lever.

The plate 7 upon which the end of the switch point swings is not provided with inner brackets, but the same has secured thereto outer brackets 65 which engage with the base flanges of the rails.

The base flanges of the main rails are provided with openings and spikes or preferably headed wood screws are passed through the openings and forced in the ties. This arrangement effectively prevents the creeping of the rails and holds the same properly spaced. Similar wood screws are passed through openings in the main rails and enter the tie upon which the yoke is arranged. Further, if desired, anchor members maybe passed through these ties, the said anchor members, designated by the numerals 67, and indicated by the dotted lines, entering the roadbed, so the rails will be prevented from moving upon the ties and the ties will be prevented from moving upon the roadbed during the operation of the switch throwing mechanism.

In Figs. 12 to 15 I have illustrated a frog 68 which is formed from a single casting, the same having its reduced end provided with a horizontal centrally arranged tongue 69 which is adapted to receive ears 70 and 71 provided upon the head and base flange at the enlarged end of a switch point 72, a pivot 73 connecting the switch point with the frog. The web of the switch point is provided with spaced openings, and if desired, centering spring members, similar to the spring bars or plates 16 may be provided but in the present instance I have also arranged upon the opposite longitudinal sides or webs of the points 62 a spring plate 74: having openings which correspond with the openings in the web of the point 7 The members 74 are bent to provide substantially U-shaped lateral extensions 75 and 76 respectively, and these extensions are adapted to contact with the inner faces of the rails when the switch point 72 has been thrown to open either the main line or the side line, and so it will be noted that by providing the plates 7 1 the brackets between the tracks upon the plates 7 are dispensed with.

In track, construction it is frequently found that portions of the roadbed where it is more desirable to place a switch are not of sufiioient width or do not contain enough ground or territory to permit of the laying of a switch of the ordinary construction-and consequently the switch must be placed at another and less desirable location. It is a purpose of this invention to provide for such exigencies and so, at a desired point in the roadbed and as illustrated in Figs. 16 and 17 of the drawings I provide one of the rails of the main track 160 with along angular or slightly curved rail 101, which provides on of the rails of the side line 102.

The frog 103 is necessarily located a comparatively great distance away from the connection of the rail 101 with one of the rails of the main track 100, and consequently a switch point of a great length would ordinarily be employed. The length of such a switch point would render the same dangerous to trailio and undesirable, as the same would be liable to twisting, buckling or turning and its operation could not be positive or dependable. Connected with the'heel of the frog 103 is what I term a trailing rail 104, the same being preferably secured to the frog through the medium of bars or plates 105 upon the sides or webs of both the trailing rail and frog and secured to the said members by bolts 106 which pass through suitableopenings in both the frog and trail ing rail. Arranged at the end of the trailing rail 101 is the switch point 107, and the c said switch point is connected with the trailing rail through the medium of comparatively heavy angle or splice bars 108 which contact with the underfaces of the head and with the base flanges of both the switch point and trailing rail and hug the webs of said switch point and trailing rails. The splice bars are secured to the trailing rail and switch point by bolts 109 passing through openingsin the webs of said point and trailing rail. The connections or joints between the frog and trailing rail and the point and trailing rail are practically rigid to effectively prevent the turning or buckling of either of said members 104 or 107.

The ties 110 upon which the rails as well as the switch are supported, are provided with the metal wear or bearing plates 111, similar to the plates 7, the said plates being provided with central longitudinally extending ribs 112 which form bearings for the trailing rail and switch point, the wear plates being secured to the ties through the medium of wood screws 113 which contact with the edges of the plates and have their heads resting upon the upper faces of the said plates below the upper surface of the ribs 112. The plates have their outer portions adjacent their ends provided with brackets 114 which may be integrally formed with the said plates and may be secured thereto, and the said brackets engage with the base flanges of the outer rails, and

" if desired, the same may be shaped to overlie the said base flanges and contact with the webs of the said outer rails. The rails 115 indicate stop lugs or brackets which are also provided upon the ribs of the wear plates 111, these brackets or lugs 115 being arranged to'the opposite sides of the switch point and trailing rail and adapted to be contacted by the same and to serve as abutments for the said members to retain the .same in alinement with either the rails of and to support the said memberspin such.

position to prevent any liability of the turning or buckling of the trailing rail and switch point. It will be obvious that by providing the switch point with the trailing rail and connecting the trailing rail with the frog, as above described the said members will yield or give sufficiently at the joints to conform to the curvature of the rail 101 with outin anywise weakening the said members, and also that when the members are thrown to close the siding the same will be perfectly straight and in registering alinement with the said main rails to close the gap between the said main rails.

From the above description, taken in connection with the accompanying drawings, the simplicity of the device as well as the advantages thereof will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains withp p out further detailed description.

Having thus described the invention, what I claim is: I I p c 1. A switch including two spaced rails and angular rails connected therewith, a frog between the angular rails, rails connected with the frog and arranged in alinement with the angular rails, a switch point connected with the frog, means for operating the switch point to bring the same against either of the main rails, spring means for normally sustaining the switch point intermediate of the rails, means for mvinging the point, and means for locking the point when thrown in either direction.
