UNITED STATES PATENT 0 7 JOHN R. wyarnor PRINCETON, KENTUCKY.

RAILROAD SWITCH.

Application filed November 22, 1924. Serial No. 751,539.

To all whom it may] concern:

Be it known that I, J GEN R. WYATT, a citizen of the United States, residing at Princeton, in the county of Caldwell and State provide switch-rails with beveled flanges so of Kentucky, haveinvented certain new and useful Improvements in Railroad Switches, of which the following is a specification.

This invention relates to improvements in railroad switches and locking means for a rock-shaft having thereon dogs for engagement with switch-point rails, of the type shown by my Letters Patent No. 848,421, dated March 26, 1907; and the invention forming the subject matter of this improvement consists in certain changes in the construction, arrangement, and combination of parts, as will. be hereinafter set forth. and

pointed out in the claims, and the object of my invention is to provide a manually operated lock for. holding the rockshaft in nonmovable position with the dogs thereon held below plane of the switch-point rails, and

when so locked not to interfere with the Operation ofa throw-bar which is connected with a switch-stand.

' The invention also provides'a' spring actuated rock-bar having thereon dogs which are spring actuated in one direction with means for limiting the rotary movement of the Y rook-bar.

points, the rook-bar having between one of" a pair of hangers a spring for moving the rock-bar in a direction to position the dogs for engagement with the switch-points, the rock-bar having between the hangers at-. tached to the opposite fixed rail a stop memrocks hand-lever 9 thatis pivoted to a horizontally ber, whereby rotative movement of the bar will be restricted.

A further object of my invention is to provide a construction andmeans whereby the dogs on the rock-bar will first exert an up ward pressure against the under side oftheswitch pointrails prior to contact with thethe spring being to hold the crank 11 raised,

flanges of-the fixed rails.

A further object of my invention is to pro-- vide the rock-bar witliflanged collars for engagement with the outer hangers of the fixed rails to hold the rock bar against lateral movement in the hangers and to provide for a sliding connection between one of the collars and the rocking-bar of the switch-stand, the other collar serving :as a

member of a lock for holding the rock-bar against rotative movement withthe dogs below the plane of theswitch-rails.

A further-object of my invention is to that theymay ride upon the flanges of the fixed rails and when so positioned the points will be on the same plane as the head of the fixed rail. I

Means for attaining the several objects of my invention are illustrated in the accompanying drawings, in connection with a switch-stand as shown in'iny prior patent Fig. 2, is a transverse section on the line 2-2, Fig. 1.

Fig. 3, is a detail section taken vertically on. theline 38, Fig. 1.

Fig. 4, is a detail section taken vertically on the line H, of Fig. 1. j

Fig. 5, is a side elevation and section, the section being taken on the line 55 of Fig. 4:. Fig. 6, is a plan view of the end portion of one of the switch-point rails.

Fig. 7, is aplan view of the other switchpoint rail; and v Fig. 8, is a side elevation partly in section of the switch-stand, which is preferably used to operate the rock-bar and throw the switch-points or rails.

The switch-stand shown by Figures 1 and 8 of the drawings is substantially the same as illustrated in my previously mentioned patent, and when it is desired to move the switch-points or rails from I the position shown by Figure l ofthe drawings, which show the main track open for trailic. When it is desired to move the switch-points the movable head of the switch-stand is swung upward so that its upper end will engage and and rail engaging, dogs or lugs in'engagement withthe movable switch-points, and when the rod is depressed .to position the dogs or lugs below the plane of the switch-.

points or movable rails. The lever 9 having v been raised to a horizontal position is moved to turn the now unlocked head of the switchsta-nd a quarter turn the head carrying with it the signal and throw-bar rod 14 by which the switch-points are moved.

The rock-shaft 12 carries collars which are located on opposite sides of an apertured hanger through which said shaft is passed and has a limited play in the hanger. The end of rock-shaft is key shaped or rectangular to enter a square socket 15, formedina collar 16 having a flange 17, the collar being fastened seciu'ely'to the end of a rock-shaft 20.

The throw-bar 18 is connected to the crank end of the vertical rod 14, being held in engagement therewith by a cotter or other pin, the opposite end of the throw-bar 18 is held in pivotal engagement with a bar 19 that is attached to the switch-point rails, preferably by means of a bolt and nut. llhe means for connecting the throw bar 18 with the bar 19, and the rock-shaft 12 with the rock-shaft 20, is preferred as it admits of ready separation of the parts in setting up and taking down or away the switch stand, and further the construction admits of the use of a lock for holding the rock-shafts inoperative when desired with the dogs on one of said rock-shafts in position below the plane of the base of the rails of the way, without interfering with theoperation of the lever of the switch-stand or the movement of. the switch points.

The locking means in simple form consist in providing the rock-shaft 20 on its end opposite to the collar 16 with a flanged collar 21 the same having therethrough an aperture which is adapted to be brought in register with an aperture through a hanger 22 secured to one of the outer rails. \Vhen the apertures are in register a pin 23 is passed through the apertures and the rockshaft 20 will be held against rotation with the switch point engaging lugs 24 belowt-he plane of the base of the rails, and in an inoperative position. A. spring 25 which encircles the rock-shaft between the hangers 26 attached to the fixed rail that is nearest to the switch-stand, the tendency of this spring 25, being to turn therock-sha'ft 20 to elevate the dogs or lugs 24: that are attached thereto. hen the lock is in use it will not in any way interfere with the throwing or operation ofthe switch rails by the lever 9, which moves the turning head of the switch stand, the vertical rod 1 1 and throwbars 18 and 19, the latter being attached to 'theswitch points or movable track points.

The two fixed

rails

27 and 28 of the way have bolted or otherwise secured thereto, between the switch supporting ties for the switch stand, similar han ers 22 and 80 which maintain the rock-shaft 20, that is of sufficient length to extend beyond the outer hangers for attachment thereto of the fixtures or collars, and between the hangers 22, the rock shatt-20 has rigidly attached thereto a sleeve 31 that has a projection 32 for engagement with the underside of the base of the rail 27 to limit the rotation of the rock-shaft 20 and prevent movement of the lugs or dogs 24 beyond a vertical position or set by the action of the springs 13 and 25, to hold the movable rails in locked position, as shown by Figs. 1 and 3 of the drawings.

The flange of the base portion of the switch-point rail 34- is cutaway or recessed as shown at 35, to provide a clearance for the inner hanger attached to the rail 28, also to provide a flat surface against which the side edge of the dog may abut when elevated. The switch point 33 is also cut away to form a clearance for the inner hanger of the fixed rail 27, and the undersides of the switch point rails are beveled as shown, the bevels 36, formed by cutting away the under faces ofthe switch point rails, permit the rails to ride upon theinner flanges of the fixed rails so the treads of the rails will be on the same horizontal when in contact.

It will be noted that bymy invention I provide a double lock for the main rails of the way, one of the locking or holding means being the throw bar 14L which is moved by the lever 9 to position its bent end in line with bar 18 that is pivoted to the bar 19 that is secured to the switch points, the second lock being the rock-shaft 20, which carries the dogs or lugs 24; that are moved upward to engage and lock the switch points, and are further held in a raisedposition by the spring 18, on the switch-stand and by a spring 25 that is attached to the rock shaft 20, thespring 25 being partially housed between the hangers 30. It will also be noted that a collar 81 on the rock-shaft 20, which collar has a projection 32 which serves to limit the movement of the rock-shaft 20, when'the dogs 24-. are in raised position, and that an auxiliary lock comprising a collar having a flange with an aperture therethrough for the passage of a pin or bolt, or other means that engages with a fixed hanger may be used to lock the rock bar having thereon the dogs, with said dogs held out of operative position, so as to admitof the switch being thrown to either position with the rock-shaft and the dogs being held in non-operative position. 7'
