To all whom t may concern:

, Be it known that I, WILLIAM W. MCCLUNG,

a citizen of the United States, residing at Butler, in the county of Butler and State of Pennsylvania, have invented a new and use# ful Switch, of which the following is a specication. f v Y This invention relates' to railway-switches,

i and has for its object to provide'a switch which is automatically moved to open and closed positions by the passage of a train and which may also be operated manually inde'- *A further object of the invention is to provide an auxiliary operating device'forming a part vof the train-operated mechanism to assist in effecting the throwing ofthe switch.

A further obj ect of the invention is to provide an auxiliary trip for automatically closing the switch should the latter be accidentally left open.A l

A further object of the invention is to provide a switch-stand movable laterally with the switch through the medium of an offset z5 bar orcam and to which are operatively connected the train-operated trips. 'l A still rfurther. object is toprovide main and auxiliary locking means for retaining the manually-operated switch-lever in vertical position. l 'l With these and other objects in view the linvention consists in thel construction and novel combination and arrangement of parts hereinafter fully discribed, illustratedin the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes inform, proportions, and minor details of construction may be resorted to without departing from the principle orV sacriiicing any ofthe advantages of this invention'.

.In the accompanying drawings, forming a part of this specication,Figure 1 is a top` plan view of a railway-switch constructed in accordance with my invention, showing in full lines the switch in closed position andl in y dotted lines the switch in open position.

Fig. 2 is an enlarged transverse sectional view taken on the line 2 24 of Fig. 1. Fig. 3 is a top plan view, partly in section, of the baseplate, cam-bar, and a portion ofthe connecting-rod. Fig. 4 is a detail perspective v iew of a portion ofthe manually-operated switchlever. Fig. 5 is a perspective view of a portion of the traineoperating mechanism detached. .Fig. 6 is a slide elevation of4 the' movableswitch-rails 7 and 8, connected by braces 9', all ofA which are of common vor approved lorm, and therefore may be varied considerably without aecting the spirit of the present invention. l

Extending transversely beneath the main rails between two of theV cross-ties 10 is a switch bar.v 11, `mounted for longitudinal movement on rollers 12 and to which is rigidly secured a plate 13. The plate 13 is provided with oppositely-disposedv threaded arms on which are mounted adjustable collars 14, the bifurcated ends of which slidably engage loops or eyes 15, securedto the adjacent side Afaces of the switch-points, being retained in engagement therewith by screws or similar fastening devices 16.`

Secured to the cross-ties` 1() at one side of the ltrack is a bearing-plate 17, provided with a plurality of sets of vertically-disposed rollers 18 journaled in suitable supportingbrackets 19 and between which is mounted for sliding movement a bar 20, having a terminal upturned lip 21. Spaced from the bar 2() is a short horizontally-disposed bar 22,

having secured to or formed lntegral therewith a segment or rack 23, formed with space notches or recesses 24. Pivoted at 24 to the central portion of the bar 22 is a hand-operated lever 25, ,to which is connected a rod 26,

which passes through an eye or opening in the lip 21 and is secured to the adjacent end of the switch-bar, as shown. Mounted for vertical movement on the lever 25 is a sliding collar 27, normally held in engagement with the locking-recesses 24 by -a coll-spring 27 and movable to released position by an auxiliary handle 28, pivotally connected to the collar through the medium of a rod 29. The

IOO

' recess 32 the lever is free to be swung pivot 24l 4to move the switch to either open lever 25 and collar 27 are formed with openings 30, adapted to register with each other when the collar is in engagement with the recesses 24 to permit the insertion of a lock or other suitable fastening device, so as to prevent an unauthorized person from operating the switch. Pivotally mounted on the bar 20 is a pawl 31, which engages a recess 32 in the rod 26 and serves as an auxiliary means Jfor locking the lever 25 in upright position. It will thus be seen that when the lever 25 is unlocked and the pawl disengaged fromthe on the or closed position, the bar 2() remaining relatively stationary during the movement of said lever.

Secured to the plate 17 on each side of the bar 20 are brackets 33, spaced at unequal distances from the adjacent longitudinal edge ofthe plate and in which are journaled rollers 34, which form bearings for a cam-bar 35. The cam-bar 35 is provided with an intermediate offset portion 36, adapted to engage a pair of rollers 37, j ournaled between the bars 20 and 22, so that when the cam-bar is moved longitudinally it will shift the bar 20 and switch-bar 1 1 laterally ofthe rails, and thereby eifect the drawing of the switch independently of the hand-operated lever 25. Pivoted to one end ofthe cam-bar 35 is a rod 38, to which is pivotally connected a train-actuated trip 39, having one end thereof bifurcated to form a pair of curved divergent arms 4() for engagement by a tappet 41, operated from the engineers cab. The trip is pivotally mounted Jfor lateralmovement at 42 between parallel supporting-plates 43, secured in any suitable manner to the adjacent cross-ties, and pivoted at 44 to the bifurcated end of the trip is a rod 44, which is in turn pivoted at 45 to an auxiliary or safety trip 45, mounted between similar plates 46 and preferably provided with a single contactarm, as shown. Pivoted to the opposite end of the cam-bar 35 is a rod 46', to which is pivoted at 47 one end of a lever 48, the latter being pivoted between supporting-plates 49, as shown at 50, and connected, through the medium of a wire or cable 51, to the pivot 44 of the trip 39.

Secured to the inner end of the lever 48 by the pivot-pin 52 is a rod 53, the opposite end of which is pivoted at 54 to one end of a trip 55, similar in construction to the trip 39 and to the bifurcated end of which is connected a wire or cable 56, which serves to connect said trip, through the medium of the rod 46, with the cam-bar 35. The cables 51 and 56 are preferably provided with turnbuckles 57 to take up any slack in said cables. It will thus be seen that when the trip 39 is moved to the dotted position shown in Fig. 1 of the drawings by engagement with the tappet 41 it will exert a longitudinal pull on the cam-bar 35, and thereby cause the latter to shift the switch-bar 11 and automatically move the switch to open position to permit the train to enter the siding and at the same time move the trip 55 to the dotted position shown, so that when the train enters the siding the tappet will also engage the trip 55 and automatically close said switch to permit the passage of any subsequent express-trains. When the train leaves the siding through the switch, the tappet 41 will engage the trip 55, causing the latter to operate the cam-bar to open the switch, and after the train clears said switch the trip 39 by engagement with said tappet will automatically close the same. Should the engineer when leaving the siding fail 'For any reason to operate the trip 39, the operating-arm of the auxiliary or safety trip 46 will be left in the position shown by dotted lines in Fig. 1, so that the engineer of subsequent through-train may readily close the switch in advance of the same by operating the tappet so as to prevent danger of side-tracking the train.

The tappet 41 is preferably mounted on the tender of the engine and operated from the cab of the latter by means of a hand-lever 5S, to which is pivoted a rod 59, mounted for sliding movement in a sleeve or collar 60 and to which is connected a rod 61. Pivoted to the rod 60 is a bell-crank lever 62, connected through the medium of a link 63 with the tappet 41', the latter being slidably mounted 'for vertical movement in brackets 64 and provided with a terminal roller 65 to prevent undue friction between said tappet and the tripping devices.

Secured to the rod59 is a transverse )in 66, which engages oppositely-disposed slots in the collar 60, and interposed between the pin and aterminal lange 67 on said collar is a coilspring 18, which allows 'for any longitudinal movement between the tender and cab without aliiecting the tappet.

As a means for insuring the positive throwing of the switch should the trips 39 and 55 fail to operate properly there is provided an auxiliary tripping device, preferably in the form of a tread-bar 69, mounted for swinging movement on rocker-arms 70 at a point adjacent one side of one of the main rails 5 and movable to operative position by engagement with the tread of the car-wheels. A rod 71 connects the bar 69 with the adjacent end of the lever 48, so that should the trips fail to operate or only partially throw the switch the wheels of the car will depress the bar and through the medium o'l the rod 71 effect the positive closing or opening movement of said switch.

From the foregoing description it is thought that the construction and operation ot the device will be readily understood by those skilled in the art, and -further description thereof is deemed unnecessary.
