SIEECIFICATION forming part of Letters Patent No. 747,774, dated December 22, 1903. Application filed J nly 8, 1903. Serial No. 164,644. (No model.)

To eY/ZZ whom it may concern:

Be it known that LISAAC BELL RITTER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia vand State of Pennsylvania, have invented certain new and useful Improvements in Switches, of which the following| is a s'peciiication.

My invention relates to improvements in railway-switches, and is particularly adapted to street-railways where a central slot between the tracks is used for the depending plow carried by the cars to enter and make contact with electrical conductors or' to en- Y gage a cable.

The object of my invention is to provide a switch mechanism which will control the switch-tongues and the slot switch-bars in the central slot, giving them a positive and simultaneous-movement and locking the same in either position-that is to say,l when the switch is opened or closed. v

My invention is provided with and operated by a pin located between the tracks, which is actedupon by an automatic switch-controller carried by the car,such as that shown and described Ain Letters Patent for .Automatic switch-controller,. No. 692,050, dated 'the 28th day of January, A. D. 1902.

A further object ofmy invention is to have the above-mentioned operating-pin concealed except when in operation. This is accomplished by the operatingpin being raised above the surface of the street by the wheel of an approaching car depressing a piu in the rail, and after the automatic switch-controlier on the car shifts the switch to the desired position the car-wheel depresses a seo-v ond pin, which causes the operating-pin to disappear.

A still further object of my invention is to provide a means of shifting the switch by a car coming from the opposite direction from where the central operating-pin is located. This consists of two pins, one in the main track and one in the branch track, and as the car approaches theswitch the wheels will contact with the pin in that particular track and-open the switch, so that the car may pass through it.

Referring to the drawings, Figure 1 illustrates a plan view of a switch', showing my ings c.

invention embodiedtherein. Fig. 2 is a side view of the same. Fig. '3 is a vertical sectional view on line 3 3, Fig. 1. Fig. 4 is a vertical sectional view on line 4 A4, Fig. 1.

Fig. 5 is a view similar to Fig. 4,.showing the In the drawings, A and A represent the I tracks on theY mainline, and A2 and A3 represent the branch tracks.

A4 represents the switch-tongues, pivoted at ai.

. B represents the central groove for the vplow carried by the car; B', the groove for the branch. track.

B2 represents plates covering the space between the tracks and central grooves to protect-the operating mechanism. f

B3 andB4 are the slot switch-bars, pivoted at b to the frame W.

The vertical shafts C and C', as shown in Figs. l ando, lare'adapted to rotate in bear- On the shafts C and C are arms C2, to which are pivoted the links C3 at c', and at c2 the said links are pivoted to the switchtongues A4. The said arms also have links C4 pivoted to th'em at c3, which said links are pivoted to the slot switch-bars B3 and B4 at. c4.

The ,links C4are provided with extensions, forming hooks C5, which engage the vertical shafts and prevent the shafts and-links from turning too far. In Fig, 1 shaft C is shown engaged by the hook C5, in which position the pivotpoints c, c2, c3, and c1 are all in line with the vertical shaft C', forming a deadcenter and locking the switch-tongue A4 and the slot switch-bar B4, so that they cannot be moved by any force applied directly to them.

The vertical shafts Cand C are rotated by' thefollowing means: Each iis-provided with an arm C6, and pivoted to said arms are the rods C7 and C8, as, shownV in Fig. 6., .The said rods are pivoted at their opposite ends to a lever C9, which is pivoted vto and carried by the lever C10, which is secured at C11 to the rock-shaft C12. It will 'readily be seen that by rotating the said rock-shaft C12 the vertical shafts will be turned and operate the switchtongues and the slot switch-bars.

As shown in Fig. l, the vertical shaft C is locked by the links; but the shaft C is not locked. To hold the shaft C in its proper position,a weight C43 is provided which acts upon the rock-shaft C12. The weight is carried by an arm C14, pivoted to the frame W. (See Fig. 6.) A link C15 connects the weight-arm and the lever C10 upon the rock-shaft C12 and holds said rock-shaft in its proper position. When the rock-shaft C12 is rotated in the direction of the arrow, the level' C40 raises the weight, and when said lever C10 has mov-ed the vertical shafts and the switch-tongues and slot switchlbars to the reverse position the weight will then hold them in said position.

The rock-shaft C12 is operated in the following manner: The said rock-shaft is provided with an arm D, as shown in Figs. 2 and 3, which is connected to an arm D on a rockshaft D2 by a rod d. The rock-shaft D2 is mounted in bearings d', secured to the side of the rails A. The said shaft is also provided With an arm D3, having pivoted thereto a rod D4, which is pivoted at d2 to the lower end of the central operating-pin E, as shown in Figs. 3, 4, and 5. The pin E passes up through a disk F and is operated upon by the automatic switch controller carried by the car. Said switch-controller, which is not shown in thedrawings, may be of any form, but preferably a block suspended from the car having a cam-surface the angle of which may be set so as to give the pin E a motion at right angles to the tracks A and A' when the said cam is brought in contact with the pin E by the moving car. The switch-controller is adapted to be set so as to move the pin E in either direction, the effect of which being to open or close the switch. The motion received by the pin E is communicated to the rod D4. (Clearly shown in Fig. 3.) Said rod is connected to the arm D3 on the rock-shaft D2, which is connected bythe arln D', the rod d, and the arm D to the shaft C12. The rock-shaft C12 communicates motion to the vertical shafts C and C through the medium ofthe level' C40, the lever C9, carried by said lever C40 and rods CT and CB, which are con nected to the said lever C9 and to the said vertical shafts. The said vertical shafts'are each provided with arms C2, which are connected to the slot switch-bars by the links O4 and to the switch-tongues by the links C2, thereby operating said switch -tongues and the slot switch-bars.

The disk F has a pin f, which is pivoted to the disk-frame F', held in the projection F2 of the frame F3. The disk-frame F is provided with an openingf, the ends of which act as a stop to limit the movement of the pin E. (See Fig. l.)

The pin E is provided with a head E', having arms E2, which enter elongated openings e in the levers E2 and E4. (Shown in Fig. 8.)

These levers are mounted upon a shaft E5, which is pivoted to the track A', and a bar E( on the frame W. Said shaft E5 is provided with levers E7 and E8, having a connectingplate E9, upon which rests a pin E40, which projects up through an opening in the track A. This pin when acted upon by the carwheel depresses the levers E7 and ES and raises the levers E3 and E4, which raise the pin E up above the surface of the plates B2, so that it may be engaged by the car. A spring G acts upon an arm g on the shaft E5 and tends to depress the levers E2 and E4, carrying the pin E. To hold the pin up against the action of said spring, I provide an extension gon the lever E4, which is engaged, as shown in Figs. 4 and 5, by a projection g2 on an arm G2 on the shaft G3, pivoted in bearings in the track A' and the bar E6. An arm G4, Fig. 2, on said shaft is engaged by the spring G, which tends to hold the arm G2 in engagement with the lever E4. A rod G5 is also pivoted to said arm G4, and at its opposite end it is pivoted to an arm G*i of the bell-crank lever G7 on the shaft G8, which is mounted in a bearing g3 on the track A. As shown in Fig. 9, the shaft G8 is provided with another arm G2,and between said arm and the arm G10 is a bar G14, supporting a pin G12, projecting up through an opening in the track A', and is acted upon by the car-wheel, which depresses it, and, as shown in Fig. 4, the arm G2 is withdrawn from engagement with the iever E4, which is then acted upon by the spring G, and the pin E is depressed.

The switch-tongues and the slot switchbars are also operated by the pins H and I. As shown in Fig. 7, the pin H is pivoted at 71, to a lever J upon the shaft J. The pin I is also pivoted to the said lever J at i. The said pins project up through openings in the rails and are engaged by the wheels of the car. The shaft J' is mounted in bearings J2, Figs. 2 and 6, and is provided with an arm J4, which is connected by a rod J5 to an arm J6 on the rock-shaft C42. It will be seen that a movement of either of the pins H or l will operate the said rock-shaft C12 and the switchtongues A4 and the slot switch-bars B2 and B4. As shown in Fig. l, the plate B5 is provided with a pin BG, which acts as a stop and holds the slot switch-bars in their proper positions.

The operation of my invention is as follows: The car approaching the switch from the left side of Fig. l depresses the pin E10 by the wheel passing over said pin. This causes the operating-pin E to be raised above the surface of the plates B2. The automatic switch-controller upon the car is then set so thatit will move the pin E and open the switch, so that the car may pass through in the desired direction. When the car-wheel strikes the pin G42, the arm G2, supporting the operating-pin E, is withdrawn and said operating-pin is depressed, so the top of said pin will be flush with the surface of plates B2. As the lOO IIO

mechanism is constructed so as to lock the switch-tongues and slot switch-bars, a carreturning through the switch could not open thev same, as in the ordinary switch. Therefore the pins H and I are provided, and the wheels of the car returning upon either the main track or the branch track A2 and A3 will contact with one of the said pins and operate the switch, soas to open it and allow the car to pass through thesame.

Having thus described my invention, I claim and desire to secure by Letters Patent- l.
