To all whomfz'thmyconcerh: g

Be it known thatI, JOHN A.'VEAZEY, a citizen of the United States,' residing'at Youngstown, in the county of Mahoning and v State of 'Ohio, have invented certain new and useful Improvements in Railway Switches; and I dohereby declare the fol-' lowing to be" a full, clear,- and exact description of the invention; such as will enable others skilled in the art to which itappertains to make and use the same.

The invention has relation to railway switches which are locked both inopen or closed position, thereby preventing accidental movement of the switch'from either the opener the aclosedposition, and in accord,

ance withthe present invention, the "pri: mary object is to prevent the derailment of a train by running into an open switch,

Other objectsand advantages will be ap parent and suggestthemselve's" as the nature of the inventio'n'is understood. 1 While the drawings-illustrate an embodiment of-the invention itis to be understood that in adapting the same: to meet different conditions and rr requirements various changesin the form,- proportion and minor details-of construction may be resorted'to without departing from the nature of the invention.

Referringzto the Fi 're 1 is atop (plan view of a railway switc embodying the invention; i 5*:

Figure 2 is a verticalqtransverse. section on the line 2-2 of Figure :1; t

Figure 3 is an enlarged sectional detail view showing the relation of the parts when the switch is open,

Figure 4 1s a slmilar view showing the disposition of the parts when the switch is closed,

Figure 5 is a sectional detail on the line 5-5 of Figure 2,

Figure 6 is a sectional detail on the line 66 of Figure 2, showing in dotted lines the:1 cut away upper portion of the ties, an

meansbeing providedrwhereby the switch is- Figure 7 is a de tail Corresponding and like parts-are referred to in the following descrlption and designated in the several views of the drawings by like reference characters.

The numeral 1 designates. the rails main track and 2 the switch points, the latterv being connected for simultaneous movement by means of a tie 3. A box 4 is slidable beneath the main rails land is con nected at one end'by meansof a link 5 with] a sw1tchstand'6 disposed atone side of the track and serving asconvenient means for,

throwing the switch when it is required to operate the same by hand.- The switch point tie 3 has a. twofold slidingmov'ement, the one with the box 4' and the otherindependently of the box and automatically operable by thetra in. whereby to throw the switch from opento closed position to prevent a casualty. Locking meansv are provided hesection on the line 7-7 of Figure 2.

of the tween the switch, point tie 3 and the box 4 to cause both to-mOve ,in unison when throwing theswitch by means of the switch stand. These locking qmeans consist. of"

similar dogs 7 and .7 and a lock member 8, the latter being disposed within the box 4: to move longitudinally therewith and having an independent vertical movement. :The' dog 7 looks the switch inopenposition and the dog .7 looks the switch in closed position.

Both dogs do' not operate at, the'same'time" andwhen one is in looking position, the other is released from-the lock memberg8'.

The lock member. 8 is provided with an-openf ing-e for eachaofthedogs7 and-'7? andthe aecomp'anyingdrawings forming a part.:oi.zthe% application:I

switch point tie 3 is: provided with an opening 10-;for eachof: said dogs; keeper 11 attached to the tie 3 extends overwthe opening '10 and,;.confines 'an:--expa nsiblei helical spring 12 normally urging thegdog 7 01'7 downwaridly whereby to cause it to enter the opening 9 when in register "therewith. Expansible helical springs 13' interposed be-, tween the bottom of the box 4 and the lock member 8 normally support the latter in elevated position and. admit of its depression whereby to clear the dog 7 to admit of the automatic throwing of the switch by the train, thereby preventing a casualty from the train running into an open switch. A pin 14. extends upwardly from the bottom of ward movement of the dog so that when the member 8: is depressed, it'clears the, dog, and admits of theswitch points being automatically moved by the train. When the switch is automatically thrown by thetrain. from open to closed position, it is locked in the closed position by means of the dog 7 To facilitate the vertical movement of the lock member 8 in the bOX'il, ballbearings:

train and this vertical movement depresses the lock member-8 so as to clear the dogs 7 and'i' thereby releasing-the switch which may be automatically thrown from open position to closed position-by a flange of 1 the car wheel engaging aside of: a switch point, andwhen the switch is closed it is automatically-locked. The usual wooden ties 22'at each side of the tie 3', have portions of their upper surfaces cut away as indicated'at 23 to permit the mainrails 1 to move vertically under the weight of a train, to depress the lock member 8.

'The dog 7 looks at tie 3 to the member Sand as the latter is movable with box 1 and the latter iscoupled to the switch stand,

it follows that switch may be thrown whenrequiredeither to the open or closedposi tion by means ofthe stand 6,'the switch being locked in either position by locking the operating member of the switch stand in any usual "orfpreferred way, I i

The box '4 may be mounted in any preferred way and is directed" in its movementsby guides 20 secured to a tie let into the road-bed. Antifriction bearings 21 are interposed betweenthe guides 20' and the box 1 to reduce the friction tothe smallest amount possible. A lever 19 is mounted in aside of' the-box 4 in position to engage a dog 7" or 7 120 admit of'either dog being} operated at will independently of the train.

' What is-clair'nedis'r V 1. Ina railwayswitch, a manually operable switch member, a train operable switch member mounted to move with the manually operable member and to have a movement independent thereof, and locking means betweenthe two members and releasable by the weight of thetrain preliminary to the automaticthrowing of the switch by the train.

carried by the-switch tieand adapted to enterthe openings of said lock member,

and elements extending' upwardly from the bottom of the box to engage said dogs and limit their'downward movement to clear the lock member when the latter is depressed:
