SWITCH.

i Specification of Letters Patent.

Patented June 25, 1907.

Appliczitioii-ilwl August' 22,1906. Serial NO- 331,680.

primarily for use with street.- railway switches;

The main object of the invention is'the provision of means wherebythe mechanism is arranged for manual control by the car operato'r, 4and under such controll may be used to o erate the switch in either direction. l'

The preferred details of construction will `be describediin thefollowing specification,-

reference being had particularly to the accompanying drawings,in which Figure 1 is a plan of a section of car track 'l illustrating the application of my invention,

the car 'and operating means carried thereby being shown in dotted outline, Fig. 2 is a ver- .tical section of the same, the car being broken away, Fig. '3 `is a transverse section through theftrack rails, the switch rod to the switch point.

R ferri'ng particularly -tothe drawings,

wherein similar reference'nmerals indicate like parts throughout the several views, 1 represents track rails, and 2 the usual switch point arranged foneo eration-with one of;

the rails, said .poi-nt eing pivotally; supported on the usual wear plate 3.-

A shifting lever 4 is ivot'ally supported between the rails 1 in a vance ofthe switch point, said leverbeing Ipreferablyfpivoted at `platel "secured to. the un -wearplates being dis osed to'uiiderlie the respective ends ofthea point Aintermediate its lendgtlli upon a wear er ying tie,4 end ever toiiisure roper l m'overnentof the latter; Therelative y rear or switchco'ntrolling' end of the lever is c'oi i' i nected tcythe switch pointv through. the Iiie-fl lis -diuin ofan operatinglrod7, the connection of said rod andswitc point being of a relatively -yielding character.- The described' connectionv is secured by passino' lsaid'rod v through thelswitch 5 ing-coil'springs 9to encircle therodo'no'p o- "site 'sides of the 'switcl'i'poinh and vbear epoint and'through an openingS-.in the web of the rail, andarrangi tween said. point and4 fixed stops v10 on the rod. .By this connection the movement of the rod is transmitted 'to the switch oint through the medium of the springs 9, w ereillustrating the connection of by a yielding..connection isprovidmi vat this point of such character as toins'ure the op' vcrationof the switch point under theinllii- .ence of the rod when said pointv is free to move,l while at the saine time permittingan 'independent movement of the, rod in the event theswitch point should be immovable through the accumulation of-foreignLinate-- 1 rial between said point and. rail.

A"lh'e relatively forwarder car controlling end'ofthe lever is provided with 'an upwardly extending postor standard 11, preferably of ward apex oredgc of the post inalinement with the longitudinal center of the lever 4.

The guiding member. is substantially of staple form,

diameter as, when depressed intol operative'position,.to 'engage the post 11 and ioo/ in one direction or the other ,a'sthe car ad varices. The springs 16 are so disposed as to lnorrnalll'yl( ove the l in Fig. 2.`

the cross bar overlying the end of the lever in advance of the postV and the points -oi the member 'being passed through the wear plate, and into the underlying tie, as clearly shown The use of' the spring 9 forms an important part oi the present invention,'as thereby op eration of the lever 4 by the oar is permitted wo'uld, of course, have a tendency to move the posta distance in excess oi the normal movement, which excess movement, if vnot com )ensated for would have atendency to -brealk some one or more oi" the connections.

I The spring connection entirelyobviates this dil iicu-lty, and permits the normal movement of the switch point under all possible conditions. The lever 4, rod 5, and connections thereof to the switch point are supported di-' rectly upon the tie structure, being in the A event ol railway bed construction. for thev streets olf cities, concealed in any desirable form of casingy having a removable cover to permit access to the working parts.

From the construction described it will be obvious that the ear operator may, by controlling the particular rod 12 desired, operi'-l ate the'switeh in either direction without' the necessity of stop ing the car.

Having thus described the invention, what Iclaimis:

in combination with the point oi' a switch, of a leverfsuitably pivoted to a wear `late intermediate its length, a rod pivote to one vend of the lever and being in yielding engagement with the point, said rod being provided with a coil spring encircling the sameI and a iixed stop at the end and intermediate the length of therod, saidtopsholding the spring in operative position, said spring passing through an opening in the switch point and through an opening in the web of the rail, a

post angular in cross section projecting upwardly from vthe lever and positioned adjacent the opposite end thereof, and aguiding member for the lever arranged thereabove, said member being suitably secured at both sides of the lever and limiting the movement thereof.

In testimony whereof, I ail'ix my signature in presence of two Witnesses.
