RAILWAY-SWITCH.

Application filed June 3, 1909.

To all whom it may concern:

Be it known that I, OSCAR O. JnrooA'r, a citizen of the United States, residing at New Brookland, in the county of Lexington and State of South Carolina, have invented a new and useful RailwaySwitch, of which the following is a specification.

The invention relates to improvements in railway switches.

The object of the present invention is to simplify and improve the construction of railway switches, equipped with track devices operated by mechanism carried by a locomotive and controlled from the cab to throw the switch in either direction for causing the train to take either the main track or the siding, as desired.

A further object of the invention is to provide a switch of this character having track devices, adapted to insure a positive movement of the switch rails in the desired di rection, and capable of securely locking the same in each position.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings :Figure 1 is a side elevation, partly in section, showing a railway switch and operating mechanism, constructed in accordance with this invention. Fig. 2 is a plan view of the same, partly in section. Fig. 3 is an enlarged horizontal sectional View. Fig. 4 is a longitudinal sectional view of one of the track devices. Figs. 5 and 6 are similar views, illustrating the two positions of the track devices. Fig. 7 is a transverse sectional view of one of the track devices. Fig. 8 is a perspective view of the operating mechanism.

Like numerals of reference designate cor responding parts in all the figures of the drawings.

The railway switch comprises in its construction opposite track devices 1, connected by rods 2 with laterally extending arms 3 of a T-shaped lever 4. The other arm 5 of the Specification of Letters Patent.

Patented Aug. 17, 1909.

Serial No. 499,973.

T-shaped lever is connected by a slot and pin connection 6 with a transversely movable bar 7, extending beneath and secured to switch rails 8 and 9 and also connected by suitable means with a visual signal 10, adapted to indicate the position of the switch rails. The track devices are reversely movable to oscillate the T-shaped lever for moving the switch rails and for changing the signal, which is preferably equipped with a light and with target wings.

Each track device consists of an oscillatory member 11, a latch lever 12 for locking the said member in one position and a trip or releasing lever 13, adapted to disengage the latch from the oscillatory member to permit the same to be moved in the direction of the switch rails for actuating the same. The oscillatory member 11, which is mounted on a transverse pin or pivot 14, is housed within a suitable box or casing 15, and it extends upward through an opening 16 in the top thereof. It consists of a plate rounded at the bottom to present a lower curved edge to the latch lever 12, and it is provided at its front edge with upper and lower shoulders 17 and 18, arranged to cooperate with a fixed pin or stop 19 to limit the oscillatory movement of the member in each direction. The stop pin 19 is located within the box or casing, which is suitably mounted on the cross ties, as clearly illustrated in Fig. 3 of the drawings. The oscillatory member is recessed at the bottom to provide a shoulder 20, and the lat-ch lever, which extends longitudinally of the casing, is pivoted at its outer end to the same by a transverse pin 21, and it is provided at an intermediate point with a shoulder 22, adapted to engage with the shoulder 20 of the oscillatory member to lock the latter when the upper portion of the oscillatory member is at the limit of its outward or backward movement. The latch lever is recessed in front of the shoulder 22, and it is provided at one side of the same with an upwardly extending longitudinally disposed segmental flange 23, presenting a curved upper edge to the lever 13, which is mounted on the horizontal pin or pivot 14. The latch is maintained in contact with the lower edge of the oscillatory member by means of a coiled spring 2&, interposed between the latch lever and the bottom of the box or casing 15 and yieldably supporting the former. The releasing or tripping lever 13 is pivoted at an intermediate point, and its lower arm is rounded at the lower end 25 to engage the segmental flange for moving the shoulder 22 downward out of engagement with the oscillatory member 11. The upper end of the latch lever is provided with a laterally extending head 26, which projects over the upper portion of the oscillatory member. The oscillatory member is recessed to receive the laterally projecting head 26 and to provide an'upright shoulder 27, which is arranged in the path of the head 26. The head 26 is normallymaintained in spaced relation with the shoulder 27 by a coiled spring 28, mounted on the oscillatory member and engaging the front edge of the releasing or tripping lever 18, and the rearward movement of the upper arm of the lever 13 is limited by a stop 29, consisting of a pin projecting laterall from the oscillatory member and locatecl in advance of the lower arm of the lever 13. The rods 2, whichextend through suitable housings 2 are connected with the oscillatory member at the curved bottom edge thereof, and when one of the oscillatory members is moved forward to the position illustrated in Fig. 6, the oscillatory member at the other side of the track is moved backward or rearward to its initial position. In this position, viz., the position illustrated in Fig. 5, the upper end of the releasing or tripping lever is arranged in spaced relation with the vertical shoulder 27 of the" oscillatory member, and when it is engaged by one of the actuating rods 30, its upper arm is moved forward independently of the oscillatory member until it engages the shoulder 27 thereof. This independent movement is suflicient to operate the latch, which is depressed by the lower arm of the latch lever. The continued forward movementof the-rod 3O oscillates the men'1-- ber 11 and carries the same to the forward limit of its movement, which position is illustrated in Fig. 6 of the drawings. This movement of the oscillatory member pulls upon the connecting rod to which it is at tached and oscillates the T-shaped lever, moving the longitudinal arm toward the side of the track at which the engaged member 11 is located. The said movement returns the other track device to its initial position and, causes the same to lock the switch rails in the position to which they have been moved.

The actuating rods 30, which are designed to be'located at opposite sides of a locomotive at the front portion thereof, are mounted in suitable guides 31, and are connected with forwardly and rearwardly extending arms 82 of a transverse rock shaft 38, journal-ed in suitable bearings of a locomotive and extending across the front of the same. The rock shaft is also provided with an upwardly extending arm 34, which is con-' nected by a rod 35 with the lower end of an operating lever 36. The operating lever, which is designed to be located within the cab of the locomotive adjacent to the reversing lever in order to be within easy reach of the engineer, is fulcrumed between its ends and is equipped with a spring actuated detent 37, arranged to engage a toothed segment 38 and operated by a latch lever. 39. The latch lever is mounted on the operating lever adjacent to the handle thereof and is adapted to be grasped and operated simultaneously with the same. When the lever is moved in one direction, one of the actuating rods or elements 30 *ill be moved downward into position for operating the track device at that side of the track, and the other will be raised clear of the other track device.

If a train should have the right of way and continue on the main line, the operating mechanism may be setto lower the actuating member at the side for moving the switch rails to close the switch, and if the switch should already occupy such position, the actuating rod or element will pass over the track device without injuring the same. The actuating rod or element will close any switch that may be open and the train will continue on the main line. A reverse move ment of the operating lever will depress the other actuating rod or element and arrange the same for opening the switch. The operating lever is also adapted, as illustrated in Fig. 8 of the drawings to be arranged at an intermediate position in which the forwardly and rearwardly extending arms will be horizontal and the'actuating rods or elements 30 will be supported clear of the track devices.

The automatic switch is designed to be used in connection with a hand operatec switch ac to permit a train locked in the siding 41 to run back onto the main line without attempting to force itself past the automatic switch. The switch rail 42 of the hand operated switch is designed to be yieldably connected with the operating mechanism, so that a train entering the siding may run past the hand switch without opening the same. Any other fo '1 r of supplemental switch, however, may be employed for returning a train from the siding to the main track after it has been locked in the siding by the subsequent passage of a train along the main track.
