1'0- all whom) it may concern.- 7

Be it known that I, CLARENCE E. KLING, a citizen of the United States, and a resident of Harrisburg, in the county of Dauphin and.

State of Pennsylvania, have invented a new and Improved Railway-Switch, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide position-until the entire train has passed upon the siding, whereupon the switch will be antomatically returned to its position for the main line, the operation being the same when a train is to pass from a siding to the main line, with the exception that the operation at such time is entirely automatic.

The invention consists in the novel construction and combination of the several parts, as

' will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a diagrammatic plan View of the improved switch mechanism. Fig. 2 is a side elevation of the outer rail-of the siding, show-- 4 and 4 are views similar to Figs. 3 and 3 illustrating the positions of the parts when the train is about to pass from the siding to the main track. Fig.- 5 is a horizontal section through the rails and connections shown in Fig. 4, and Fig. 5 is a horizontal section through the rails and connected parts shown in Fig. i. Fig. 6 is a side elevation of a part of the main rail from the opposite side of the track and showing the positions of the parts when a train is to pass from the main track to the siding. Fig. 6 is a continuation of Fig. 6, showing the position of the parts of the switch at the siding, the track being viewed from the same direction as in Fig. 6. Fig. 7

is a plan view of the parts shown in Fig. 6,

andFig. 7 is a plan view of the parts shown in Fig. 6*. I

' A represents a portion of the main track, the rails whereof are designated as 10 and 11.

B represents a siding which connects with the main track, the rails of the siding being designated as 12 and 13.

G represents the switch-points, which are shown in position to leave the main track open.

C represents the bridge-rail in the main track leading to the siding, and C the fixed point or frog which is usually employed in connection with a bridge-rail;

At the right-hand side of the main track A, adjacent to the outer rail 11 and at any desired distance from the switch-points C, a lever 14 is fulcrumed, usually at its center, by means of a suitable pin 15, properly supported, as is shown in Figs. 1 and 7 and a connecting-rod 16 is pivoted to the outer end of the lever 14 and is likewise pivoted to an elbow-lever l7, suitably fulcrumed at a point adjacent to the said rail 11 of the main track. This elbow-lever 17 is connected by a link 18 with a second elbow-lever 19, as is also shown in Figs. 1 and 7 I At the right-hand side of the main track A, at that part where the switch-points C are located, a rocking plate 20 is fulcrumed at or about the center, and the said rockin plate adjacent to what may be termed its inner end is provided with a stud 21, which extends upward from the plate, and when the stud 21 is in operative position, to be hereinafter described, said stud is brought opposite a peripherally grooved and horizontallyto an elbow or bell-crank lever 25, which is opposite that portion of the main track which is opposite that portion of the siding B that connects with the said main track, and another connecting-rod 26 is pivotally attached to the elbow-lever 25. This latter connecting-rod 26, as is shown in Fig. 1 and partially so in Fig. 7 extends beneath the rails of the IIO main track and the rails of the siding to a connection with an elbow-lever 27, which is suitably pivoted adjacent to the outerrail 13 of the siding B, as is shown in Figs. 1 and 5.

An arched trip-lever D is located at the right-hand side of. the main track A or at the outer face of the rail 11 of said track, as is best indicated in Fig. 1 and, as is shown particularly in Fig. 6, this arched trip-lever D consists of two links 28 and 28, the link 28 being preferably shorter than the link 28. The link 28 is nearest the operating-lever 14 and is pivoted, by means of a suitable pin 29, to the outer face of the said main rail 11, and the two links 28 and 28 are pivotally connected by a pin 30. The link 28, which extends in direction of the switch, is provided at its free end with a longitudinal slot 31, and a pin 32 is passed through this slot 31 into the outer face of the main rail 11, as is shown in said Figs. 1 and 6, so that the members of the arched trip-lever D may be carried down straight or parallel with the rails adjacent to-j junction with the member a of the said slide 34 a connecting-bar is employed, constructed in two pivotally- connectingsections 36 and 37, (best shown in Fig. 1,) the two sections being connected by a pivot-pin 38. The section 36 of this divided connecting-bar is pivotally attached to the member a of the slide 34, while the other member 37 of the same connecting-bar is pivotally attached to a bellcrank lever 39, pivoted upon a suitable support adjacent to the main rail 11, where the switch-points O are located, as also best shown in Fig. 1. The membered connecting-bar thus described passes between the stud 21 on the rocking or revoluble plate 20 and the aforesaid grooved guide-pulley 22, and when the members of this divided and pivotallyunited connecting-rod are straightened the action is brought about by the rocking of the said plate 20 in a manner which will bring the stud 21 of the plate against the member 37 of the said connecting-rod and will carry the said member to an engagement with the grooved surface of the friction-pulley 22, as is shown in Fig.7. At such time the two sections a and a of the slide 34 are made to abut, or practically so, as is shown in Fig. 7, and when the members 36 and 37 of the divided connecting-rod are at angles to each other, as shown in Fig. 1, the members of the arched trip-lever D may be carried down parallel with the rail 11 without interfering with the section a of the slide. In fact, dividing the slide 34 admits of lost motion at the arched lever-trip D for a purpose to be hereinafter set forth.

The switch-points C are suitably pivoted and are attached to a shifting or switch bar 40, which extends beneath the rails of both the main and the siding tracks and has free sliding movement at such point. The switchbar 40 extends out some distance beyond the outer rail 13 of the siding-track B, and a guide-arm 41 is attached to the said switchbar 40, which guide-arm, as is best shown in Fig. 5, is rendered vertical at its outer end 42 and is provided at such end with an aperture 43. The end 42 of the guide-bar 41 has movement in a guide-loop 44, which extends upward from a plate 45, suitably supported, and this plate 45 is provided with standards 46 and 47 parallel with the guide-loop 44. The said standards 46 and 47 of the guideloop 44 are provided with alining apertures adapted to receive the straight end 48 of a locking rod or bar 48, to be hereinafter described, and this locking rod or bar 48 is brought into action when the switch-points have been shifted to establish communication between the main track and the siding or the siding and the main track, at which time the aperture 43 in the guide-bar 41, connected with the switch-bar 40, is brought into alinement with the apertures in the standards 46 and 47 and the guide-loop 44, so that the straight end 48 of the locking-bar 48 will at such time not only pass through the apertures in the members of the plate 45, but likewise through the aperture 43 in the guide-bar 41, thereby locking the switch in the position to which it was shifted.

The lever 14, which is operated to shift the switch whena train is to be switched from the main track A to the siding B, is operated by a device controlled by the attendant in the cab of the engine. Such a device is shown in Fig. 6 and consists of a vertical arm 49, having guided movement in bearings located at the pilot of the engine 50. The said triparm 49 may be given movement, as is illustrated in Fig. 6, through the medium of an elbow-lever 51, fulcrumed on the framing of the pilot and connected by a suitable link 52 with a lever in the cab of the engine. One member of this elbow-lever 51 is shown pro vided with a slot 53, which receives a pin 54, carried outward from the trip-arm 49, and when the trip-arm is in its lower position, or in a position to engage with the inner end of the lever 14 to operate the same, the trip-arm 49 is held in its lower position by the engagement of a suitable latch 55 on the said arm with a keeper 55 on the pilot. After the located adjacent to the rail 11 of the main 57, which is mounted uponasuitable support. adjacent to the outer rail 13 of the siding-' track B, as is shown in Fig. .1, and a spring 58, attached to this lever 57 and to a suitable support, serves to hold the switch-bar in such position as to normally retain the switchpoints C in a position to cause the main track to be normally open.

dium ofa link 59, is pivotally attached to an arm 60, which extends down from one member of asecond arched trip-lever D. This second trip-lever D is located at the outer face of the siding-rail 13 at a point beyond the fixed frog C as shown best in Fig. 1. This second arched trip-lever D consists of two members 61 and 62, of which the member 61 is preferably the longest, and these two members are'pivotally connected by a suitable pin 63. In the member 61, from which the arm extends, a longitudinal slot 64 is produced, and a pin is passed through this slot into the outer face of the outersidingrail 13, while the corresponding end of the shorter link 62 is pivoted directly to the same 25 and 27 and their connections, the lever 27 is so turned as to draw the end of the triplever D in direction of the switch, carrying said lever from its normal positionparallel with the rail 13, as shown in Fig. 4,to an' upper arched position corresponding to that of the trip-lever D. (Shown in Fig. 6.) At the same time through the combined action of the connecting- rods 16, 19, and 24 the rocking plate 20 is turned so as to bring its stud 21 against the member 37 of the divided connecting-rod, straightening the said rod and bringing it to the position shown in Fig. 7, and as this divided connecting-rod is thus straightened the member a of the slide 34 connects with the member a of said slide and forces such member in direction of the main operating-lever 14, thus bringing the trip-lever D to theupper arched position. (Shown in Fig. 6.) When the wheels of the engine reach the arched trip-lever D, they force the said trip-lever downward, so that its members are parallel withthe rail 11 of the main track,

whereupon through the medium of the slide 34 and the elbow-lever 39 the switch-bar 40 is moved against the tension of its spring 58 and in a direction to carry the switch-points from their normal positions to their shifting positions, establishing communication between the siding and the main track. As the train passes forward and before it reaches the switch by mechanism to be hereinafter described and located adjacent to the outer rail 13 of the siding and outer rail 10 of the main track the switch-points are locked in their shifted position, and the train then passes on to the siding, and when the arched levers D are reached, the members having been raised as just above described, said members are pressed downward by the wheels passing over them and the locking mechanism is released from the switch-bar and the spring connected with said bar is permitted to act to restore the switch-points to their normal position. At the same time the elbow- levers 27 and 25 are operated upon to operate the rods 24, 23, and 16, restoring the main shiftinglever 14 from the main track to its normal position. At the same time the rocking plate 20 is turned so as to relieve the member 37 of the divided connecting-rod from the pressure of the stud 21, carried by the said plate, whereupon a spring 38, connected to one of the members of the said divided connecting rod and to a fixed support, will draw the members of said rod to the position shown in Fig.

1 at angles to one another, and thus separate the sections a and a of the plate 34, permitting the arched trip-lever D to be forced down to a position parallel with the rail 10 of the main track the construction is as follows: A

jointed shifting-lever D is located adjacent to the jointed trip-lever D-namely, at the outer side of the outer rail 13 of the siding B, as is best shown in Fig. 2. This shifting-lever D when pressed downward by the weight of a train passing over the rails is adapted tocarry the switch-points in such position as to connect the siding with the main track, whether the train approaches said siding from the main track or approaches the main track from the siding. This jointed shifting-lever D consists of two links 66 and 67, the link 66 being the shorter of the two, and the link 66 is at what may be termed its outer end pivoted to the rail 13 by means of a suitable pin 68, and the two links 66 and 67 are connected by a pin 69. At what may be termed the outer or free end of the link 67 of the said jointed shifting-lever D a longitudinal slot 7 O is produced, and a pin 71 is passed through this slot into the said .rail 13 of the siding B, so that the jointed shifting-lever D may occupy the arched position (shown'in Fig. 2) or the flat position parallel with the rail 13, as is shown in Fig. 3. In fact, the shifting-lever D is of the same character as the trip-lever D and the trip-lever D, heretofore referred to, and these levers D, D, and D will behereinafter designated as jointed levers. A

connecting-rod 72 is attached to the cuterend of the link member 67 of the join-ted shiftinglever D and this rod 72 is pivotal-lyconnected with a member of an elbow-lever 73, suitably mounted adjacent to the siding-rail 1-3,

and the elbow-lever 7 3 is connected by a link 74: with another elbow-lever '75. The elbowlever 75 is connected by a' bar 76 with the bellcrank or elbow lever 57, connected directly with the switch-bar 40, as is clearly shown in Figs. 1, 5, and 5. Two slides E and E, the slide E being the inner one, are mounted for end movement at theouter faceof @thesidin-grail 13 and the corresponding rail 10 of the main track A, connecting with the said sidingrail, as is shownparticularly in Figs. 4 and 4, 5 and 5, and likewise in Fig. 1. These slides E and E have movement in suitable supports 77, connected with the bottom of the rails 13 and 10, or with any supports for said rails. The outer slide E is provided with a series of longitudinal slots, the slot which is farthest away from the switch and nearest to the jointed shifting-lever D being designated as 78, the next slot as 7 8, the third slot as 79, and the fourth slot as 7 8"; but the number of slots in :the said slide E may be varied as required in practice. A pin 80 is attached to the inner slide E, and this pin extends out through the slot 79 in the outer slide E, as is clearly shown in Figs. 4 and 5. A rod 81 is pivota-lly con- .nected with the pin 80 and with the springcontrolled elbow-lever 57, connected with the switch-bar 40, so that it will be observed that when the jointed shifting-lever D is pressed downward to throw the switch, which operation may be performed by the train passing over the said shifting-lever D or by engagement with the operating-lever 14:, as the switchpoints are thrown the innersl-ide E is drawn in direction of the said jointed shifting-lever D A pin 82 is passed from the inner sliding bar E outward through the slot 78 in the outer sliding bar E, and a second pin 82 is passed from the inner bar E out through the slot 7 8 in the outer bar, while a third pin :82 is passed from the said inner sliding bar E out through the slot 78 in the outer sliding bar E. The pin 82 is received by the upper end of a rocking arm 83, the pin 82 being re ceived by a corresponding arm 83*,and the pin 82 is received by the upper end of .a third rocking arm 88, all of which arms are pivotally mounted in any approved support, as is clearly shown in Figs. 4 and 4:.

In connection with the jointed shifting-lever D two correspondingly-formed locking-levers D and D are employed. These lockinglevers are adapted to carry the locking member 48 of the locking-arm 48 to or from engagement with the -:controlling-bar of the switchpoints as the switch-points are to be moved to'a shifted position or are to be moved from such position. The locking-lever D consists of two links 8A and 85, the link being preferably the shorter, and these links are connected by a suitable pivot-pin 86. The outer end of the longer link 84 is pivotally attached to the outer face of the outer slide E adjacent to the end which faces the jointed shifting-lever D and the outer end of the other or shorter link 85 of the said lockingle-ver D is pi-votally connected with the pin 82, which passes through the slot 78 in the outer sliding bar E, thus affecting aconnection with the inner sliding bar E. Thus, it will be observed, that one link member of the lock-lever D is indirectly connected with the inner slide E, while the other member is directly connected with the outer slide E. With reference to the lock-lever D, it is of substantially the same construction as the lock-lever D being purely a duplicate thereof. This latter lock-lever D*, as is shown in Fig. A, consists, for example, of a long link 87. pivotally attached to the outer face of the outer slide E and :a shorter member 88., which is pivotally connected at its outer end with the pin 82", which passes through the slot 7 8 in the outer slide E to an engagement with the inner slide E. These link members are connected by a suitable pivot-pin 89.

As-pring is attached to the end of the outer slide E,which is carried in direction of the main track A, and the said spring 90 is secured to .asu-pport adjacent to the rail 10 of thesaid main track, as is show-n in Figs. 1, 4c, and 5; but the straight portion of the spring 90 passes over a friction-roller 91, suitably located. A stud 92 is projected from the outer face of the outer slide E, where the vspring'90 is connected therewith, and the locking-bar 48* for the switch-bar is attached to this stud in any suitable or approved manner. The operation of the parts to the right of the main railnamely, the parts operated by the lever l4:has been described; but in brief it may be repeated that when a train approaches the switch from the main track and is intended to be carried onto the siding B the lever 14: is operated at its free end in direction of theswitch, which action throws the switchpoints to a position to establish communication between the siding and the main track and at the sametime raises the jointed trip-lever D at the siding-rail to the upper arched position. (Shownin Fig. 6".) As the switchpoints are shifted to establishsuch communication between the main track and the siding the jointed shifting-lever D is drawn down parallel with the siding-raii 13 by the action of theswitch-bar 40 passing from one position to the other. At such time the two jointed locking-levers D and D will be raised by the operation of the jointed shifting-lever D on the inner sliding bar E, causing the said bar to be drawn in direction of the said lever D and consequently causing the two lockinglevers D and D" to be carried to an upper elevated position. Therefore after the switch has been shifted by the depression of the jointed trip-lever D the train in its passage to the switch will first strike the nearest'locklever, which will be the lock-lever D, and will force that lever downward to a position parallel with the track adjacent to which it is located, thus carrying the outer bar E to a position in direction of the jointed shiftinglever D and as the bar E is carried to this position the lock-bar 48, connected with the said slide E, will be carried in the. same direction and'will pass through the aperture in the guide member of the switch-bar, thus locking the switch-points in place. At the same time the spring 90 is placed under tension.

The train will now travel on until it has well passed the switch, and when the wheels of the cars strike the trip-lever D of the siding and compresses the said lever, as has been stated, it will restore the parts at the right of the main track to their normal position, and as the last wheel of the last car leaves the shifting-lever D the said lever is permitted to rise to its upper or normal position, owing to the spring 58 acting at such time to draw the switch-bar L0 in position to restore the switchpoints to their normal place, and at about the same time the spring 90, connected with the outer sliding bar E, acts to draw the locking device from engagement with the operative mechanism of the switch-points, permitting the switch-bar 4:0 to be actedupon by the spring 58. When a train is on the siding and is to be directed to the main track, the jointed shiftinglever D will be in the position shown in Fig. 2, and the two lock-levers D and D will likewise be in a position parallel with the rail adjacent to which they are located, as shown in Fig. 2. example, engage with the jointed shiftinglever D the said wheels compress said lever, as is shown in Fig. 3, and cause the lock-levers D and D* to. be elevated by the sliding action of the slides E and E, as is shown in Figs. 3 and 3. When the jointed shiftinglever D is pressed downward by reason of its connection with the SWIllClI-DHJ 40, which has been described, the switch-points are drawn to the position to establish communication between the siding and the main track, and as soon as the wheels of the train approach the first lock-lever D said lever is depressed, and the outer slide E is acted upon in a manner to force the lock-bar 48 to locking position with the switch-bar 40, thus holding the switch-points in shifted position, and

at the same time by the same action of the slide E the other lock-lever D is depressed, so that the train passes on until the last wheel As the wheels of the engine, for

of the train clears the last lock-lever .D,

whereupon the mechanism just described as brought into action is released and the lockbar 48 is carried from looking engagement with the switch-bar 40, and the jointed shifting-lever D by the automatic return movement of the switch-bar 4:0 is carried to its normal elevated position.

It may here be remarked that the jointed lock-lever D sustains the same relation to the switch when a train is leaving a siding for the main track as does the trip-lever D when the train is leaving the main track and passes onto and along the siding.

Having thus described my invention, I claim as new and. desire to secure by Letters Patent 1. In a switch mechanism, a main track, a
