A umnommeemember 10 i9i2i semamaraaooa To all whom it mayeon'oera't Be it known that'I, ELIJAH F. JOHNSON, a citizen of the United States, residing at Union Mills, in the county of Rutherford and State of North Carolina, have invented new and useful Improvements in Connecting-Rods for Switches, of which the following' is a specification.

This invention relates to railroad switches, the object being to provide adjus-table meansfor connecting the movable switch points with the switch-stand mechanism whereby proper adjustment of the! switch points maybe effected at all times to insure proper operation thereof andto prevent lost motion. v e

A further object ofthe invention is to provide adjustable means connecting the movable switch points with each other and with the said stand to allow for the relative movement of the switch points with each other and with the connectin rod extending to the switch stand.

With these and other objects in View, the invention consists-of certain novel features of construction; combination and arrangement of arts: as will be hereinafter describedand claimed. a

In the accompanying drawings :,Figure 1 is-a' plan view ofthe device; Fig. 2 is a transverse sectional view, taken on the line a-2 of Fig; 1- ;-'and Fig. 3 is a longitudinal sectional view through one of the adjustable connecting members.

In the drawings, the numerals 1 and 2 designate the movable switch points. A transversely extending rod 3 is secured to the switch pom-t2 adjacent its free end and oppositely screw-threaded as at '12 and 13,,

has its inner end screw-threaded as at 4:,

. 4W this erfd of the rod'being threaded into a transverse threaded opening 5 in the bolt portion 6 of an adjustable connecting mem* her 7. This bolt portion is rotatably mounted between the arms of a yoke-shaped cufl portion 8 of the connecting member.

jacent its free end and has both of its ends the threads at 12 being opposite to the threads at 4 on the rod 3. Its inner thread-' ed end 13 is adapted to be extended-through the threaded opening 14 in the second yoke Thecurved connecting portion 9 of this cuff is or suificient size and rigidity to retainrits; semicircular-shape, and isprovided with an arcua-te slot 10. A second rod 11 extends transversely through the switch point 1 admember 15, which form's a portion of the connectingmember and whichis provided with further through thearcuate slot 10 in the cuff 8-. The belt portion of a similar connecting member 17is adjustably connected to the oppositely "threaded end 13 ofthe rod 11 and the: cuff-portion of this member is adjnstabl yconnected tothethreaded end 18 crank 20 ofthe stand mechanism 21. It will thus be seen that, when it is desired to adjust the movable switch points with relation of a connecting'rod' 19' which extends to the to each other so as to-insure proper engage ment thereof with the track rails,- it is merely necessary to rotate the cuff- 8'of the connecting member disposed therebetween and there will thus be a certain amount of deflection between the two rods 3 and 11,

this being accounted for by the double pivotal action ofthe connecting member connecting the adjacent ends of the said rods, without affecting the relative distance "between the switch points, no matter what the adjusted position of the connecting member may be. During this action, the bolt portion-rawill swing upon its pivots and the-curved portion 9 of the cufi 8 will swing slightly through the slots 16 in the yoke 15, the threaded end 13 of the rod 11 being movable through the arcuate slot 10 in the curved portion of the cufi. Similar action will occur in the connecting member 17 during operation of the switch as will be readily understood fromthe" foregoing descriptionof the operation of the other con nesting member and which will be due to the different angular positions of the connecting rod 19.

Having thus descibed my invention, what I claim" is "1. In adevice of the class described, the

combination with a pair of movable switch points and operatingmechanism therefor, of."

tially in transverse alinement, a connecting member adjustably mounted upon the ad-j jacent ends of said rods, the said member being adapted to permit relative angular movement of the said rods, and means for connecting one of the switch points with the switch operating mechanism.

2. In a device of the class described, the combination with a pair of movable switch points and operating mechanism therefor, of a pair of rods secured individually to the said switch points and disposed substantially in transverse alinement, a connecting member mounted upon the adjacent ends of said rods, the said member being pivotally connected to one rod for movement in one plane and connected to the other rod for movement in an angularly disposed plane, and means for connecting one of said switch points with the switch operating mechanism.

3. In a device of the class described, the

combination with a pair of movable switch points and operating mechanism therefor, 01" a pair of rods secured individually to the said switch points and disposed substantially in transverse alin-ement, a connecting member mounted upon the adjacent ends of said rods, the said member being pivotally connected to one rod for movement in one plane and connected to the other rod for movement in an angularly disposed plane,

- the said connecting member being longitudinally adjustable upon one of said rods, and

means for connecting one of the switclr points to the switch operating mechanism.

4:. In a device of the class described, the combination with a pair of switch points and operating mechanism therefor, of a pair of rods secured individually to the said switch pointsin substantially transverse alinement, means for connecting one of said switch points with the operating mechanism, and a connecting member including a bolt portion mounted upon the inner end of one of the said rods, a yoke portion having its extremities pivotally mounted upon the bolt portion, and a second yoke portion mounted upon the adjacent end of the coacting rod and provided with alining slots in its arms slidably receiving the curved cross portion of the first yoke portion.

5. In a device of the class described, the combination with a pair of switch points and operating mechanism therefor, of a pair of rods secured individually to the said switch points in substantially transverse alinement,means for connecting one'of said switch points with the operating mechanism, and a connecting member including a bolt port-ion mounted upon the inner end of one of the said rods, a yoke portion having' its extremities pivotally mounted upon the bolt portion, and a second'yoke portion mounted upon the adjacent end of the coacting rod and provided with alining slots in its arms slidably receiving the curved cross portion of the first yoke portion, the first yoke portion being provided with an arcuate slot in its curved portion receiving the second rod.

6. In a device of the class described, the combination with a pair of switch points'and operating mechanism therefor, of a pair of rods secured individually to the said switch points in substantially transversealinement, means for connecting one of said swltch points with the operating mechanism, and a connecting member including a bolt portion mounted for longitudinal adjustment upon the inner end of one of the said rode, a yoke portion having its extremities pivotally mounted upon the bolt portion, and a second yoke portion mounted upon the adjacent end of the coacting rod and provided with alining slots in its arms slidably receiving the curved cross portion of the first yoke por-- tion.

7. In a device of the class described, the combination with a pair of switch points and operating mechanism therefor, of a pair ofrods secured individually to the said switch points in substantially transverse alinement, means forconnecting one of saidswitch points with the operating mechanism, and a connecting member including a bolt portion mounted upon the inner end of one oi" the said rods, a yoke portion having its extremities pivotallyfmounted upon the bolt portion, anda second portion mounted for longitudinal adjustment upon the adjacent ELIJAH F.
