SWITCH.

Specification of Letters Patent. Patented N0: 9

Application filed March 25, 1920. Serial No. 368,538.

To (ZZZ who m, may concern:

Be it known that I, Josnrrr lV. Krnnnnnr, a citizen of the United States, residing at lVarren, in the county of Cochise and State of Arizona, have invented certain new and useiiul improvements in Switches, of which the following is a specification, reference be ing had to the accompanying drawings.

This invention relates to certain improvements in switches, and it is an object of the invention to provide a novel and improved device of thisgeneral character embodying a movable frog point which is operatively connected with the switch points so that the position oi the frog point is governed by the switch points and in a manner to produce a closed it'rog, thereby giving the wheels of the rolling stock a continuous rail on which to run during a switching operation.

The invention consists in the details of construction and in the combination and an rangement of the several parts of my improved switch whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous iior use, a will be iereinafter more fully set forth.

The novel features oi my invention will hereinafter be definitely claimed.

In order that my invention ma y be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a fragmentary viewin top plan and partly in section illustrating a switch constructed in accordance with an embodiment of my invention, the mechanism for throwing the switch points being diagrammatically indicated; and

Fig. 2 is a view in perspective of the frog point detached.

As disclosed in the accompanying drawings, R denotes the rails of the main line,

- and B the rails of the branch line, and with which coact the switch points S. The points S are tied by the cross rod 1 whereby said points S move in unison and inthe same general direction. M indicates diagrammatically any desired. mechanism whereby the requisite endwise movement may be imparted to the rod 1 for throwing the points S as desired.

F denotes a frog point coacting with the adjacent guard rails 13 and R',and which frog point is mounted for swinging movement relative to said guard rails, and for which reason the point F ispivotally en gaged atone end, as indicated at :2, with the frog A.

The pivoted end portion of the frog point.

F is provided with an inwardly directed arm 5 terminating 111 a vertically disposedplate 4: having disposed therethrough an open ing 5. Loosely directed through the opening 5 is an end portion of a rod 6 disposed be tween the rails It and movable in a direction longitudinally thereof. The rod 6 at opposite sides of the plate l is provided with the stops or enlargements 7 and interposed between each of said enlargements 7 and the plate a is an eXpa-nsible member 8. As herein disclosed each of the members 8 comprises a coil spring encircling the rod 6. v

'The rod 1 at a pointbetween the switch points S is provided with an upstanding pin 9 which extends within a longitudinally dis- 7 end portion of the second arm 6 of the bell crank lever L.

When the switch points S are thrown through the medium of the mechanism M the bell crank lever imposes the desired strain or stress upon the rod 6 to throw the frog point F substantially in unison with and in the same general direction as the switch points S so that a continuous rail is provided with the rolling stock when traveling over the main line or on to the branch or side line. It will be self-evident that the tensionof the member 7 is sufficient to impart the desired swinging movement to the point F through the medium of the arm 3 and at the same time compensates for any inequality of the relative movements of the points S and the point F. i

C denotes a casing or housing in which the rod 6, the bell crank lever L and the majorportion of the arm 3 are contained so that the same are effectively protected against the elements or the like, so that the desired operation of my improved switch is assured.

From the foregoing description, it is thought to be obvious that a switch constructed in accordance with an embodiment of my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and" operated, and it will also be obvious that my invention is susceptible of some change and modlfioation wlthout departing from the principles and spirit thereof, and for this reason I do not wish to be understood as through the arm the frogpoint, arod disposed longitudinally or the main ra1ls,i'an operative connection betweenthe first named rod and the second C named rod whereby endwise movement is imparted to the second named rod upon 'the throwing of the switch points, said second named rod being loosely disposed of the frog point, and yieldable members carried by the second named rod at opposite sides of the arm of the frog point and contacting with said arm whereby the frog point is moved in unison with and in the same general direction as the switch points, 7 7

- In testimony whereof I hereunto afiix my signature.
