These means comprise a lever 1.1 and an arm In accortlanceidwith the present improve c, which is prel'craltlli' horixonlal. piojectiing ments the .manual operation ol the switch is trom the shal't (1' and extending; through a elected throughtlie single mmcineiit ol a slot fin the opcratinj 1l lever g1. This arm ilever oi' some such means which movement pi\ orally secured to a hlocli /i upon a quart-o im? not onliv serves to t-"i-"ow the switch but also portion ol the .shall being l'orlo d at onev to release .the manually l eratine` means end in order to embrace this Il from the automaticall)Y operatingv means. ln 1 other end constitutes a projection anni:

tends through the slot f in the lever g and which also engages, `by means of recesses i, the block b. lt will thus be seen that every time the switch'is' moved and the shaft d is turned, the arm e will be swung around from one side of the stand to the other. As the arm e normally rests in one of the recesses 7l, the stand, when automatically operated by a passing'train, will cause the block b to rotate against the action of the spring actuated rollers a. Then however the arm e has been lifted from its engagement with either of. the recesses r,the shaft CZ ma f be freely turned and the switch thrown independently lof the automatic means, that is independently of the block b and the spring actuated rollers a'. For lifting this arm e and manually throwing the switch, the lever g with the slot f, already referred to, has been provided. `This lever g is pivoted near its lower end and arranged so as to swing in a practically vertical plane. The slot fis of such conforma- ,"tion as first to, raise the arm e from its engagement with the recess t as the lever g sta'rts to move, and then to cause said arm to be swung over'and finally permitting it to drop again into t-he other recess i. For this purposethe slot may be made approximately pear shaped as illustrated in Fig. 1, said slot or a portion thereof obviously constituting a cam whereby the desired movement of the -arm e is effected. Themanual operation of such a stand will be seen to be extremely simple. All that is required is the lswinging vof the lever g in a singleplane and. in a single direction to change its position from one side `of the vertical shaft to the other side, and involving an angular chance of about ninet o y o z:

l`here are no projections from the.

degrees. stand which can possibly constitute any obstructions to passing trains and for this reason too the stand may be set up in a comparatively small space where it would be impossible to accommodate a stand having a horizontally swinging lever. Moreover, it

will be easy to see how a wire or cable could be attached to the operating lever g whereby it could be operated from a distant signal tower as easily and conveniently as a semaphore..

It is, of course, possible to provide means as illustrated at m (Figs. 1 and '2) through l which a padlock or the like may be passed in l order to lock permanently the arm e in one or the other of the recesses t and., therefore to lock the switch from any manual operation for an indefinite time. V"doreover, other additions or changes may be made in the construction shown and described without departing from the spirit of the invention` ll'e claim as our invention:

l. In a switch stand, the combination of means to control the automatic throwing of a switch, manually operated means to throw automatic means, and means to disengage the manually operated means from the autoL matic means and thro the switch in a single operation.

. 2. In a switch stand, the combination of 'means to control the automatic throwing of a. switch, manually operated means to throw the'switch normally in engagement with the automatic means, and a lever' adapted to lmove in a single plane and as it-moves in said pla-ne to disengage the manually operated vmeans from the automatic means and throw the switch. l

In a switch sta-nd, the combination of means to control the automatic throwing of a switch, manually operated means to throwv the switch normally in engagement with the automat-ic means, and a lever adapted to move in a vertical plane. and as itr moves in said Aplane to disengage the manually oper-v ated means from the automatic means and throw the switch. u

4. In a switch stand, the combination of means to control the automatic throwing of a. switch,- an arm through which the switch maybe manually thrown normally in engagement with the automatic means, and a lever adapted to move in a'single'plane and as-izt moves in said plane to disengage the arm from the automatic means and throw vthe switch. y

5. In a switch stand, the .combination of means to control the automatic throwing of a switch, a. substantially horizontal arm through which the `switch maybe manually thrown normally in engagement with the automatic means, and a lever adapted to move in a vertical plane and as it movesin said plane toA disengage the arm from the automatic means and throw the switch.

6. In a switch stand, the combination of means to control the automatic throwing of a switch, a substantiallyhorizontal arm through which the switch may be manually thrown normally in engagement with the automatic means, and a lever adapted to move in a vertical plane and having a slot through which the arm extends whereby as the lever is moved in said plane it disengages thearin from the automatic means and swings it around to throw the switch,

7. ln a switch stand provided with means Yto control the automatic throwing of a switch, the combination of a horizontal arm through which the switch may be thrown manually, means to lock the horizontal arm to the automatic means whereby the switch cannot vbe thrown independently of the automatic means until the arm is unlocked from the automatic means, and a lever adapted to move in a vertical plane and having a slot therein through which the arm extends, whereby thc movement of the lever in either direction first unlocksthe .arm from the 4automatic means the switch normally in engagement with the l then swings the arm to throw the switch and Jan 9. In a'switch stand, the combination of a vertical shaft adapted t'o be operatively connected to a switch, means to control the automatic throwing of the switch including a block adapted to `loe turned by the shaft when the-.switch is automatically thrown,

manually operated means to throw the switch normally in engagement withl the block, and a lever adapted to move ina single plane and, as it moves in said plane to disengage the manually operated means the block and throw the switch.

10. In a switch stand,

a vertical shaft adapted to be operatively connected to a switch, means to control the automatic throwing of the switch including a block adapted to be turned by the shaft when the switch is automatically thrown, a4

lever adapted to move in a verticalplane and 4around to throw the switch inde the automatic me ans. from' the combination ofsubstantially horizontal arm through which the switch may be manually operated normally in engagement with the block, land a as it moves in said plane to disengage vthe arm from the block and throw the switch.

' 11.l In a switch stand, the combination of a vertical shaft ada ted to be operatively connected to a switc means to control the automatic throwing of the switch-including a block adapted to be turned bythe shaft when the switch is automatically thrown, a substantially horizontal arm pivotally connected with the shaft through which arm the switch may be manually operated, ,means whereby the arm and block normally engage, and a lever adapted to move in'a vertical plane and having a 'cam slot through which the arm extends whereby as the `lever moves in said plane, the arm isfirst lifted so as' to disengage it from the block 'an flthen'swung'.` Y
