SWITCH.

Application led August 31, 1915.

T0 all whom, t may Concern Be it known that we, EDWARD H. lDAiILKn and Morris L. Sirs CLaiR, citizens ot' the United States, residing` at Bonne T erre and Frankclay, in the county of St. Francois and State et Missouri, have invented new and useful limprominente in Switches, of which the following is a specification.

The-present invention relates to improve ients in railway construction.

ln' carrying out'our invention it is our pur` Y pose to provide a switch between the main and side lines which shall be operated by mechanism arranged upon an engine to move the switch to, say, openthe same to the main line to close the switch tothe siding, and wherein, after the train has passed the switch, will return the same to its initial position.

Ve also aim to provide a switch which is operated by mechanism connected with a train with signal device actuated by the bridle rod or an element connected with the bridle rod so that the engineer ot' an appreaching` train will be warned or can readily ascertain the position of the switch, and thus be in a position to operate the switch operating mechanism if necessary.

It is a further object of the invention to provide switch throwing means which may be automatically actuated by mechanism upon a train or which, lit-desired, may be operated by an approaching train so as not to necessitate the stopping of the train and the inconvenience ot' one ot the train hands leaving the same to actuate the switch, but which may be also operated by hand if desired, and further wherein the hand operating mechanism will not interfere with the automatic or train operating mechanism.

A further object et the invention is to provide a construction ot this character which shall be extremely simple, easily and quickly applied, cheap to manufacture, and which shall be positive and sure in operation.

lili-th the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts vset t'crth in the following specification and talling within the scopeof the appended claims.

Referring now to the drawings in detail, the numeral l designates the tracks oi `the main line, and 9; the tracks ci' the siding. 3 designates the switch rails which are ar ranged between the main line and siding, and the points ot the switch are connected by the usual bridle rod l. which, in the present instance` has pivotally secured thereto a rod extension 5, and the 'said extension has its end pivotally connected with a link G which in turn is pivotally connected with the offset end or foot. 7 ot a target rod 8. The target rod is arranged in suitable bearings provided in a switch stand 9, and the said rodliasits end whichprojects above the said switch stand provided with the usual laterally extending different colored plates which form the target 10. vWhen the switch is thrown in one direction, it will be noted that the rod 8 will be rotated to bring two of its target arms transversely of the track, these arms being each of a similar color, and

also that when the switch is thrown in an opposite direction, the second pair of target arms will be swung transversely of the track, the said second pair of arms being of a different color from that of the first mentioned target arm, and so it will, of course, be apparent to the engineer of the locomotive approaching the switch that the said switch is either in an open or a closed position. It is, of course, to be understood that if desired, at night a lantern having different colored bulls eyes may be arranged upon the rod 8 above its target arms and the dilierent eolored lenses of the bulls eyes will serve as an indicator for the engineer so that the posi-V tion of the switch may be readily ascertained, this arrangement being common in the art, an illustration thereof is not deemed necessary.

Positioned at approximately anequal distance from the switch 3 to, say the outer side of the main line and to the inner side of the switch line are trip members of aV similar construction, but indicated for distinc-` tion by the numerals 11 and 12, the trip member 11 being for the main line and the trip member 12 being for the siding. Each of the trip members is substantially Y- shaped in elevation and the angularl arms 1313 of the said Y-shaped members have upon one of their faces laterally extending ofi-set portions or flanges 141L The connecting member for the angular portions of the Y-shaped clips have each secured thereto a shaft 15, the said shafts extending below the rails of the main line and journaled in j main track 1.

Pivotally secured, as at 20, to one of the ties which project beyond the inner rail of the main line opposite the switch 3, is a fiat plate 21, the said plate resting upon at least two of the ties.v T he free end of the plate is preferably provided with an elongated slot 22 which is arranged concentric of the pivot 20,

' and this end of said plate is preferably covered by a flanged plate or housing 23, a pin 24 passing through the housing and through the slot 22 inthe said plate 21. The plate 2l which, for convenience, will hereinafter be referred to as a rest plate, has arranged upon its upper face adjacent its pivoted end vertically extending stop members 25 and 26 respectively, the same being disposed in angular relation to each other and adapted one to at all times contact with one of the edges of an arm 27 which is approximately centrally pivoted to the rest plate 21, as indicated by the numeral 28. One' oftheends, which may be termed the inner end of the pivoted arm 27 has connected thereto the offset end of the rod 19, and the second end of said arm has loosely arranged thereon a link 29, the said link being in turn pivotally secured to the longer arm of an L-shaped lever 30, and this lever is pivotally secured preferably at the juncture of its angular arms to the rest plate 21, as indicated by the numeral 31. The pivot 31 also serves as a connecting' member for a llat bracket 32, and the said bracket has one of its ends connected to a link 33 which is pivotally secured to the arm 27 adjacent the pivotal connection of the rod 19 with the said arm 27,. The bracket member 32 is approximately centrally connected by the pivot 31 to the rest plate 21 and its end, opposite that to which the link 33 is connectedv` is formed with an upstruck lip 3d. Also the lonOer armof the L-shaped lever 30 has its end formed with an upstruck lip35. The lips 34 and 35 have arranged the. aon a longitudinal adjustable member 36 the said members 36 being connected with the opposite ends of a helical spring37. The spring 37 is arranged to normally swing the lipped ends of the L-shaped lever 30 and the bracket 32 toward each other for a purpose which will presently be set forth.

The rod 18, which is connected to the shaft 15 of the trip 11 has its free end loosely secured to the L-shaped lever 30 adjacent the pivotal connection of the link 29 to the said lever.

The shorter arm of the L-shaped lever 30 has pivotiilly secured thereto, as at 39, a

bracket d() which issecured to the extension 5 of the bridle rod fl. 1t will thus be noted that when one of the trip members, say the trip 12, is contacted (in a manner Vpresently to be described) the shaft 15 of the said trip will be turned and the rod 18 will be moved longitudinally, thus swinging the arm 27 upon its pivot 28, and likewise, through the link connection between the l shaped lever and the said arm as well as the link connecticn between the bracket 32 and the said arm 2?, both of the rods 18 and 19 will bemoved in unison and the switch thrown.

It will be noted that when one of the Y- shaped or angular arms of either of the trip members contacted to swing the same to a horizontal position, the second arm of either of the said members will be arranged in a vertical position, or in a position to be again contacted to operate the. switch, as will, it

:insana-e is thought, bennderstood. The throwing Vot the switch actuates the' target. 10,.but the vsaid target may be movedor swung without interfering with the trip* members, as will 5 hereinafter be more fully set forth.

Secured to the rest plate 2l `adjacent the non-pivoted or sliding end thereot' is an oti- `:set or angular end fil'of a memberf42, the end ot' said member Vextending approximatelyA centrally over the tie-upon-which the switch stand 9 is arranged, but terminating a suitable distance away from said stand, and the free end oi the member Ll2 is termed or otherwise provided with an odset socket i3, through which passes for slidable movement, a substantially rectangular arm il, the said arm all entering the switch stand and being pivotallyv connectedto the oiii'set end 45 of a vertical, shaft-46 which is. ar- .20 `ranged.inloearings in the switch stand. The

upper end Vof ythe isha ft. e6. liassecured thereto an angular arm 4.7, and .thelsaid arm has .its ifree --end bifureated .and `ipivotally 1 secured with-in 'the said biturcatiorn:l ,as aiia.l is lever 49. fLilie .top ot' the 4switch ystand .has a projecting edge `which.y is curvedyand provided,'adjacent its ends, with .notches 50,either of said notches adapted` to receivethe lever 49 afterthe same is employed for 30 rotating the shaft i6 and for normally holding the switch either open or closed to the main line, vshould it be found desirable to operate the said switch 'bythe said lever. The numeral 51 designates a second or auxiliary operating lever which is pivoted, adjacent: one of its ends, fas at 52, to the member 42, while its lower end is pivotally connected to the arm fle. `The switch stand construction permits of the switch being 40 actuated by hand. `Theatuiliary `lever 5l being pivoted to the arm 4A awayifrom its pivotal connection 52 with. thexmember lll through themedium ot the socket 43 L' permits of the sliding of the said member 42 45 when the said lever al is swung in either' direction, such movementswinging the rest plate 2l upon its pivot `20.an`d through the connection between the said rest plate, the bridle rod .-l will swing thel switch points 3, at the same time, ihroughthe mediumiot the link 6,. connected with thev otfsetgend of the target rod will simultaneously turn the said target rod, consequently turning `the target arms. The switch points 3 `may be also directly operated `by the turning of the shaft 46 of theswitch stand through the manipulation of the lever' .49. The lever i-9 is swung in a line with the arm 48 `andis turned upon the switch stand. The offset end vl5 of the lever 46 influences the arm 4A and which arm, through fthe medium of its pivotal connection with the auxiliary lever will swing the said leverupon its pivot 52 inthe direction of the memberv 42. .This

. le5 ,provides ari gidcoimetionqbetween:thelever `5l, the arm, iflv and thev'member` e2, causing these `members to movein unison Aand consequently swing the plate-2l upon its pivot 20land throw Vthe switch points 3 `and the target arms i6. .The spring 3'? holds the parts associated with the rest plate 2l in tion and will be referred. to by like designat- .lngzcharacters,itis to be stated that the pro- 'ectino contact-.rod of the l.en ine isada )ted to be extended Sor projected inthe sideoi` :said .fei'igine from one side 'of lthe engine ufhichfis opposite the sidenpon whichthe .contactrod Vofthe cabooseor end car is projected, .so that when one oi the trip members contacted by the contact member of the car, the said trip member will not again be contacted by the member upon the said last car ot' the trai n, but the neXt or second trip member will be actuated by the mentioned contact member upon the last car to return the same to its initial position.

Arranged within the cab of the locomotive and at a suitable point in the last car or Caboose, is a lever 55, the same being connected with a transverse shaft 56 which is journaled in suitable bearings 57 upon the underframe of the vehicle. and the said shaft `has one of its ends provided with `an otfset `strap or link 6i which has its end secured to a transversely extending Contact member or rod` 62, the said contact member being journaled in suitable bearings 63 and one of the Abearings may have a-closed end or the connection between the .strap andthe said contact member may be so arrangel as to engage with one of the bearings toprevent the lateral `sliding movement oit the contact member62 in one direction, so that the same will be projected from only one side of the vehicle, for a purpose previously described. The shaft 56 is provided with an angular extension 6i to which connected a rrod having a pivotalconnection with one of the/arms of abell crank lever 66, and to the second arm of the said bell crank lever is secured a rod 67 that-.is connected with or. may :form .apart of a ,rod 68,the latter will liti dlg@ Y being pivotally connected with a bell crankmembers 01'126, and from the foregoing,

when taken in connection with the drawings, the constructioi'i and operation et the device will, it is thought, be apparent without further detailed description.
