To all whom it may concern:

Be it known that 1, SMITH 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 Switch-Stands, of which the following is a specification.

My invention is an improvement in switch stands, and has for its object to provide mechanism in connection with stands of the character specified for moving the points of a switch to deflect trains from the main track on to the switch, wherein locking mechanism is provided for locking the switch points insafety or main line position and connected to the operating mechanism for moving the points in such manner that when the operating arm for the switchis moved into inoperative. position after returning the points to normal position, the locking mechanism will be operated to lock the points against movement.

In the drawings: Figure 1 is a perspec tive view of the improved stand. Fig. 2 is a top plan view of a portion of a switch with the siding open and the locking mechanism with parts in section.

The present invention is a division of my prior applicati0n,Serial No. 790,918, filed September 20th, 1913, issued as Patent No. 1,120,529, December 8, 1914, and the stand is ofusual construction, comprising the table 1, having legs 2, which aresupported by a plate 3, secured to a base block or extension tie 4. The operating shaft 5 is journaled in the stand, and the said shaft is connected with the points 6 by means of a rodfi the said rodbeing connected at one end to the points, and at the other to the crank 6 at the bottom of the shaft 5 for moving the same toward and from the main line rails 7, the said connection forming no part of the invention and for this reason not shown.

The shaft 5 is oscillatedin the usual manv nor to move the points by means of a lever 8, and the lever is pivoted to the outer end of holding the levers and the points in open or closed position.

Lugs 13 and 14 are connected with the table above the notches 11 and 12, and each lug-13 and 14 is provided with a-slot for engagement by a perforated locking lug 15 on the lever. When the arm is swung downward as indicated in Fig. 1 into engagement with either notch 11 or 12, the' lug15 will pass through the slot of the adjacent lug 13 or:14 and the shackle of a pad lock is passed through the perforation of the lug to lock the lever in the notch.

A pin 16 is arranged transversely. of they upper end of the lever above the arm 9, and the upper face of the arm is provided with a transverse groove or notch 17 for receiving the pin when the lever is in alinement with the arm. 'Thepin 16 extends beyond the arm when in the notch, and is adapted to engage" an opening 18 in a sliding block or plate 19, arranged adjacent tothe notch 11, and movable against a vertical extension 20 from the table.

The inner end of the sliding block or plate is pivoted toone of the arms 21 of a threesignal is operated by the same mechanism that moves the points.

The arm 23 0f the rock lever is connected by a link 26 with one of the arms 27 of an elbow lever pivoted at 28 to the stand and having the otherarm 29 thereof connected by a link 30 with the locking mechanism for the points. A casing 31 is connected with the base block 4 of the stand, and a locking plate 32 is slidably mounted inthe casing. The locking plate is connected to the points 7 by a link 33, the link passing through a per forated lug 34 on the adj acenti point of the pair, and being engaged by a nut 35 on the opposite face of the lug from the locking plate to permit the parts to be adjusted with respect to each other. t i

"The casing is provided with a transverse Goplea oithis patent maybe obtained for p g t Washington, D. G.

opening and the locking plate 32 has an opening adapted to register with the opening 7 of the casing when the points are in safety position, and the registering openings are The operation of the improvement is as follows: When the switch lever 8 is raised into alinement with the arm 9 and out of engagement with the notch 12 of the stand, the said lever maybe swung toward the sliding block 19 to throw the points from side track to main line position. WVhen thelever .8 is moved toward the locking lug 13 and just as the lever passes above the notch 11, the end of the pin 16 enters the opening 18 of the sliding block or plate 19, and when the lever is pushed downward into engagement with the notch 11, the block or plate 19 is moved toward the locking lug 13. This movement of the block or plate swings the three armed rock lever in a direction to cause the arm 23 thereof to move downward. The link 26 communicates this movement to the elbow lever 27 -28, and through the link 30 such movement is communicated to the locking pin in a direction to cause the looking pin to move inward to engage the registering openings of the casing and the looking plate.

is in engagement with the opening of the sliding. block or plate the lifting of the arm moves the sliding block or plate away from the locking lug 13, thus swinging the three armed lever in a direction to cause the pin 36 to be withdrawn from the registering openings of the casing and the locking plate.

When the switch points 6 are set for the main line position, the pin 36 positively locks the plate and the points, so that even should the switch stand be torn from its position by a swinging door or the like, the points will remain locked and the main'track will remain clear.

rock lever for moving the pin from the openings when the switch points are moved to open from closed position.

In a switch stand, thecombination with the operating shaft journaledvertically in the stand and connected with the points for moving the same when the. shaft is oscillated, of alever mounted to swing into and out of horizontal position and connected with the shaft for oscillating the shaft, said stand having notches for receiving the lever to holdthe points open or closed, a rookiever pivoted at the stand, a locking plate connected with the points, a guide in jCOIlnection with the stand, the plate being movable in the guide, said guide and plate having openings registering when the points are closed, a locking pin for engaging the openings, a connection between one arm of the rock lever at the stand and the locking pin for moving the pin into the openings when the locking lever is moved inone direction, a block slidable onthe stand adjacent'to a notch, said levervhaving a cross pin and the block an opening for engagement by the pin when the lever moves into register with the said notch, the other arm of the rock lever being connected to the block, said block being moved by the lever when it engages with the notch in a direction to engage the locking pin with the openings.
