Application filed May 20, 1914.
T 0 all whom it may concern:
Be it known that I, RICHARD L. PnnnroniUs, a citizen of the United States, residing at Smithville, in the county of Bastrop and State of Texas, have invented certain new and useful Improvements in Switch- Stands, of which the following is a specification.
This invention relates to switch stands and has for an object to providea stand with means whereby the target is turned to danger as soon as the switch is unlocked, irrespective of whether the switch is thrown open or not.
A further object of the invention is to provide a switch stand having a switch operating spindle and a target spindle independent of each other with means for rotating the target spindle from the switch spindle rotating lever.
With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more fully de scribed and claimed.
In the drawings: Figure 1 is a view of the improved switch stand in perspective. Fig. 2 is a view of the operating mechanism below the deck of the switch stand. Fig. 3 is a view in elevation of one of the levers of the operating mechanism. Fig. 4 is a view in perspectiveof one of the levers. Fig. 5 is a view in side elevation of the target spindle bracket. Fig. 6 is a view in edge elevation of the target spindle bracket. Fig. 7 is a plan view of one of the levers of the operating mechanism. Fig. 8 is a view in side elevation of the operating lever shown at Fig. 7.
Like characters of reference designate corresponding parts throughout the several views.
The improved switch stand which forms the subject matter of this application comprises a deck 10 supported in any approved manner as upon the standard 11 which is mounted in the usual manner upon crossties 12 and is adapted to actuate a rod 13 to throw the switch.
It will be apparent that the operating rod 13 will be moved by the rotation of the switch spindle 14.- which carries a crank 15 pivoted to the rod 13 and has a lever composed of the parts 16 and 17 whereby the spindle is rotated in the usual well known manner to throw the switch. In the ordi- Specification of Letters Patent.

Serial No. 839,762.
nary switch the spindle 14 is continued upwardly and the target is carried upon the same spindle.
The present invention embodies an auxiliary spindle 18 which is journaled in the deck at 19 and is further strengthened by a bracket 20 rigidly secured to the deck in any approved manner as indicated. At its upper end the spindle 18 carries a target 21 of substantially the usual and ordinary type.
B neath the deck the target spindle is provided with a collar 22 which carries a lever 23 and a link 24 is pivoted to such lever as at Pivoted also beneath the deck is a lever 26, the fulcrum point being at 27 and provided with a pin 28 engaging in the slot 29 of the link 21. It is obvious that when the lever 26 is swung upon its pivot 27 it will serve to move the link 24 and the lever 23 to dotted line position and thereby impart to The target spindle l8 rotation of substantially ninety degrees. The lever 26 carries a lug 30 which extends under the notch 31 in the deck so that when the section 17 of the operating lever is thrown downwardly to the position shown at Fig. 1 to enter such notch 31 it moves the lever 26 from the full line position to the dotted line position and, therefore, throws the lever 23 from full line to dotted line position. lVhen the lever section 17 is lifted a spring 32 acts upon an arm 33 of the lever 26 to throw the lever 26 back to full line position and consequently to throw the lever 23 also to full line position. The full line position of the lever 23 holds the target spindle 18 at danger while the dotted line position holds the target spindle at safe. It is obvious, therefore, that as soon as the lever section 17 is raised to release the lever section 16 and permit the rotation of the spindle 11 the target turns at once to danger without awaiting the rotation of the switch spindle 14 and that it remains at danger until the switch is entirely closed and the lever section 17 forced downwardly to the position in which it is locked in the usual and ordinary manner.
I claim:
1. In a switch stand, a notched deck, a switch operating spindle, a target operating spindle, a lever for operating the last mentioned spindle, a portion of said lever overlapping a notch of the deck when the target is at danger, means for normally holding said lever in said overlapping position, and a switch operating lever adapted to enter said notch and engage the target lever.
2. In a switch stand, a deck provided with notches; a lever rotatable about the deck and provided with a hinge permitting one section to enter the notches; a target spindle journaled vertically above the deck; a lever beneath the deck adapted to rotate the target spindle; a lever adapted to be actuated by the jointed operating lever; and a link connecting the levers beneath the deck.
3. In a switch stand, a deck provided with notches; a jointed lever fulcrumed centrally of the deck and movable about its'periphcry and one of the sections adapted to enter the notches; a target spindle erected vertically above the deck; a lever mounted beneath the deck and having alug extending outwardly into one of the notches of the deck and in the path of movement of the jointed lever; and means connecting the lcver beneath the deck with and to rotate the target spindle when the jointed lever enters the notches.
4. In a switch stand, a deck; a. target spindle j ournaled vertically above the deck; a lever pivoted beneath the deck and extending outwardly over a notch formed in the deck; a lever secured to the target spin-- dle beneath the deck; a link connecting the two levers beneath the deck; and a spring adapted to hold the levers beneath the deck yieldingly with the target at danger.
In testimony whereof I aiiix my signature in presence of two witnesses.
