SWITCH-STAND.

Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed April 1912. Serial No. 689,826.

To all whom it may concern:

Be it known that LSMrri-I F. PHILIPS, a citizen of the United States, and a resident of El Paso, in the county of El Paso and State of Texas, have invented a new and useful Improvement in Switcli-Stands, of which the following is a specification.

My invention is an improvement in switch stands, and has for its object the provision of a signal device for use in connection with the operating mechanism of a switch, for in dicating, by a visible signal, the position of the switch, and means for operating the signal so arranged that the switch operating mechanism cannot be operated until the signal is set at danger.

A further object is to provide means in connection with the switch operating mechanism for positively preventing the return of the signal to safety position until the switch has been returned to its original position.

A further object is to provide a housing for the signal, in which the signal is held when the switch is in normal position, the casing having an opening for permitting the signal to be moved out of the casing, and a door normally closing the opening, and means operated by the signal moving means for opening and closing the door.

A further object is to orovide a signal mechanism capable of use y day or night.

In the drawings :-Figure 1 is a perspective view of the improvement, with the parts in one position; Fig. 2 is a similar view, with the parts in another position; Fig. 3 is a longitudinal section of the upper portion of the stand; Figs. 4 and 5 are sections on the lines 4-4 and 55 respectively of Fig. 3; and Fig. 6 is a bottom plan view of the operating arm.

In the present embodiment of the invention, the stand 1 is provided with the usual table 2 at its upper end, the table having a series of notches 3 and 4 in its periphery, for receiving the switch lever 5 when the switch is locked. The base 6 of the stand has openings '7 for receiving spikes or the like to hold the stand in place, and the standard or body of the stand is provided with a bearing 8 for the shaft or rod 9. The rod 9 extends above the table and a casing 10 is supported above the table, by means of metallic straps or bars 11, each of which is secured at one end to the table, as shown at 12, and

at the other end to the casing. .The casing is provided with a door opening in one face, normally closed by a door 13 hinged to the casing at 14.

A signal post 15 is connected with the upper end of rod 9, the said posthaving a socket or recess 16 in its lower end, into which the rod extends. The post 15 extends longitudinally into the casing 10 to .near the upper end thereof, and the upper end of the post is provided with a recess or socket 17, for receiving one end of a stub shaft 18, and a pinion or gear wheel 19 is integral with said shaft at the center ithereof. The upper end of the stub shaft is square in cross section for receiving a swltch l1ght, and the operating arm 20 for the switch is provided with a bearing ring 121, which encircles shaft 9, between the table and the lower end of shaft 15. The said arm is recessed or slotted from its outer end, as indicated at 22 (Fig. 6) to form a pair of spaced lugs, and the lever 5 is pivoted between the said lugs. A pin 23 is passed through the ring 21 and shaft 9, to

hold the arm rigid with respect to the shaft,

and a pin 24 is'passed through the lugs of the arm and through the lever 5 to pivotally connect the arm and lever. The said pin passes through the lever near one end, as shown in Fig. 3, so that when the lever is swung upwardly into alinement with the arm, the upper end of the lever fits in the slot or recess 22.

The post 15 is provided with a transverse slot 25, just above the arm, and a second lever 26 has one of its ends extending through the slot. The said end of the lever is curved upwardly as shown in Fig. 3, and a link 27 has its lower end pivoted to the saidend by a bolt or pin 28. The lever 26 is provided with a laterally enlarged portion on the opposite side of the postfrom the link, and with a vertical opening 29 in the said enlarged portion. The lever is also provided with a downwardly and inwardly extending arm or lug 30 between the opening and the post 15, for engaging the slot 22, when the upper end of lever 5 is in the opening 29. The said upper end of thelever 5 has an opening 31 for receiving the shackle of a padlock to lock the switch from movement. The link 27, before mentioned has its upper end pivoted at 37 to an car 32 on a semaphore 33, which is pivoted to the post 15 by means of a. screw 34. The said screw 34 (Fig. 1) is passed from the outside of casing 10 through a boss 35, through a bearing 36 on the arm and is threaded into post 15. The semaphore is in the casing and means is provided for opening the door 13, in order to permit the semaphore to swing into danger position. The said means comprises an elbow lever 3839, pivoted at- 40 at the junction of the arms to the post 15. The arm 38 in longitudinally slotted at 41 and a pin 42 is passed through the slot and into engagement with link 27. A. link 43 is pivoted at one end to the outer end of arm 39, and at the other end to an eye 4A on the inner face of the door 13. When the link 27 is pulled downwardly by lever 26, the elbow lever is rocked, the arm 38 swinging downwardly, and the arm 39 outwardly, and the link 43 swings the door open on its hinges 14 to permit the semaphore to swing out of the casing.

In operation, when the switch is in inoperative position, the lever 5 stands approximately vertical, the upper end thereof extending through the opening 29 of lever 26 and a padlock may be engaged with the opening 31. The lug or arm 30 of lever 26 is engaged with the slot 22 of arm 20, the semaphore is in the casing, and the door 13 is closed. To operate the switch, the padlock is unlocked, lever 26 is lifted to the dotted line position of Fig. 3, and the semaphore is swung outwardly, the door 13 opening before the same, by means of the elbow lever 3839. The arm 20 is provided with an integral upwardly extending wing or vane 45 at one side of the slot 22, the highest portion of the wing or vane being are shaped, and concentric with post 15, while the portion adjacent to lever 5 is inclined, the upper edge inclining downwardly toward the lever. The lever 26 is notched on its lower edge adjacent to post 15, as shown at 46, and the wing or vane will prevent the swinging of lever 5 angularly when lever 26 is lifted into the dotted line position of Fig. 3 that is into position to move the semaphore into horizontal position. With lever 26 in this position, as soon as lever 5 is swung angularly, the wing or vane 15 holds the lever 26 elevated, and positively prevents the lowering of the semaphore until'lever 5 has been returned to its original position, and the switch has been closed. After dark, a lamp or other illuminating means will be placed in the square piston 47 at the upper end of stub shaft 18. Such lamps, as is known, are provided with a pair of oppositely arranged white panes or windows and with a pair of oppositely arranged red panes or windows, the red indicating that the switch is out of main line position.

The semaphore 33 is provided with a laterally extending arc-shaped flange 48 provided at its free edge with teeth for engaging and rotating the pinion 19 and the stub shaft 18. When the semaphore is swung into the danger or horizontal position, the shaft 18 is partially rotated, far enough to bring the red panes or Windows into position to be seen in either direction on the track. The switch can not be thrown from main line position until the semaphore played. The device also prevents the malicious displacement of the switch with the safety signal displayed since the switch cannot be set for the siding and the signal at safety.
