SWITCH-STAND LQCK.
rose
To all whom it may concern:
Be it known that l, Qrmnnns Noon, a citizen of the United States, and a resident of ldoulton, in the county oi Appanoose and State 01" Iowa, have invented a new and useful Improvement in Switch-Stand Locks, of which the following is a specification.
My invention an improvement in switch stand locks, and has for its object the provision of simple inexpensive means in con nection with a switch stand for locking the operating lever to the stand, with the switch in open or closed. position, wherein the loc ing means is actuated by the dropping of the operating lever into inactive position.
A further object is to provide means in connection .vith the locking means for permitting the locking means to be disconnected trmn the operating lever, in case it should be necessar to operate the switch with no key at hand, to prevent breaking or the lock.
In the drawings :--l igure 1 is a plan view of the improvement; 2 is a section on the line 22 of Fig. 1; and and 4- are sect-ions on the lines 3-3 and 1- 1: re-- spectively of Fig.
In the present embodiment of the invention, the top plate or table 1 oi. the switch stand has a central opening for the operat ing shaft or rod (3 of the switch, and is also provided with spaced notches or recesses 2 and, in its side edge for receiving the lever or handle t, which oscillates the rod or shaft. The lever is pivoted to an arm 5, secured rigidly to the shaft 6 above the plate 1. @no end of the lever tis received in a notch or recess 7 in the outer end of the arm, and
0 a bolt or rivet 8 passed through the arm and the lever to pivotally connect the lever to the arm. When the lever is not in use, it rests in one of the notches, the particular notch depending upon whether the switch is set for the main line or for the siding.
To throw the switch the free end of the lever is swung; upwardly until the lever is in alinement with the arm. in such position, the. upper end 01": the lever fits the notch,
52 and by swinging the :ll'll'l to the right or left, the switch is thrown. When the lever is released, it drops into the position of Fig.
2, and by its engagement with a notch 2 or 3 acts to hold the switch closed.
The standa ."d switch. lock is a spring lock,
consisting oil. a body 11, and a shackle 12.
Specification of Letters Patent.
Serial No. 696,622.
Patented Mar. 1914i.
Renewed January 20, 1914. Serial No. 8. .3.275.
An angle plate 9 10 is secured to the arm at one side of the notch, the portion 5) being held to the arm by rivets or bolts 9. The portion .10 of the angle plate has one of its faces in alineinent with the adjacent side wall of the notch 7', and the body 11 of the lock secured to the said portion, and is held in a position to rcce've the locking tongue oi the shackle, which carried by the lover. The body is held to an extension 13 on the portion 10 ot the plate 9---10, by means of bolts or rivets 1st, which pass through the body and the extension. The bolts 14; are ot' course arranged in such a inaln'ier that they do not interfere with the ope .ation of the lock. The extension 13 is provided at its upper edge with a lateral flange 15, which extends across the upper edge ot' the body. The shackle 12 oil the lock is provided at the end remote from the catch 23, with a pair of spaced peritorated cars 24, and a slotted lug 25 on the body is received between the ears. A pin or bolt 26 is passed through the cars and the slot of the lug and also through the portion 10 of plate S 10. the said bolt or pin pivotally connecting the shackle to the bodv. The shackle is received in a. recess 27 in a channel bar 28, having" a pair of depending lugs 29 and 30 at each end. The shackle is also provided with a pair of spaced cars 31 at the end adjacent to the itch 23, and the said ears are pivoted to the ears 80 of the channel bar by means of a pin The ears 29 of the channel bar are pivoted to the upper end of lever 4, one ear of the pair being received on one side edge of the lever and the other in a slot 5 in the lever. A bolt 17 is passed through the ears and the lever tor pivotall connecting the channel bar to the lover. The channel bar is longer than the shackle, so that the lever 4. is at the end of the shackle, and the said shackle may rest within the recess of the channel bar.
The pin 32 may be of any desired c0nstruction and is held in place by heading one end-the other end by a cotter pin. The outer end 01 the channel ot' the cha nel bar is pr .ably closed, shown at 18 and the recess is partially closed by a web 18preterablv iron construction. The shackle is held by the channel bar in such a. posi ion that when the lever il: is dropped into either of the recesses 2 or 3 the catch of the shackle is forced into th body, pushing the spring latch or bolt aside and looking the shackle to the body. Whenever the lever is so dropped into either recess 2 or 3, the switch is locked, and the action is entirely automatic, no attention whatever being required. It is probable that an emergency might arise when it would be necessary to operate the switch, and when the person desiring to operate the switch would have no key. In such case, where no means is provided, the lock would necessarily be broken. The peculiar connection between the channel bar and the lever 4c however, permits the channel bar to be released from the lever by removing pin 17. To remove the said pin it is not necessary to injure the lock which is left in locked position. It will be evident that when the lever at is disconnected from the channel bar the lever may be operated in the usual manner. It will be noted that the slot of the lug 25 permits the shackle to be entirely disconnected from the body.
The closed end 18, and the web 18 of the channel bar protect the outer end of the shackle, and the inner end is rounded or beveled, as shown at 12 Fig. 2, in such manner that the adjacent end of lever 4, acts against the said end to press the catch 28 of the shackle into the lock body.
A shield 13 is secured to the portion 13 of the angle plate and the said shield extends over the inner 'end of pin 17 to protect the same. hen the shield is knocked off or bent down, the pin 17 may be removed by driving it out.
I claim 1. in combination with the switch stand, the operating shaft, and the laterally disposed arm secured to the shaft and provided with a recess for receiving the operating lever when said lever is in alinement with the arm, and the operating lever pivoted to the arm, of means for locking the operating lever to the arm when said lever is swung out of alinement with the arm, said means comprising a padlock composed of a locking body, and a shackle, means for securing the shackle to the lever, said means comprising a channel bar pivoted at one end to the upper end of the operating lever, the shackle being received in the channel of the bar, and a pivotal connection between the opposite end of the channel bar and the adjacent end of the shackle.
