Application filed November 5, 1914. Serial No. 870,335.

T all rLai/wm it may concern:

Be it knownl that we, GEORGE W. GwrNN and ANDREW GwYNN, citizens of the United States, residing at lSalt Lake City, in the county of Salt Lake'l and State of Utah, have invented Acertain new and useful Improve- -ments in Railway-Switches, of which the following is aspecification.

Our lnvent'ion relates to improvements 1n railway switches, and refers to thanA class of switches which are opened by means carried by the car.

The object of our invention is the provision of means which will be absolutely reliable in operation, which wil'l be Simple, strong and durable to withstand hard usage, and whichwill be inexpensive ,of production, to insure an efficient and practical 1mprovement of this character.

IVith this object in view our invention consists of a railway switch embodylng novel features and combination of parts substantially as shown, described and particularly defined bythe claims.

Figure 1 is a plan view of the main track,

switch or point and switch mechanism,-Fig.

' 2 is a perspective view of the means for operating the switch -mechanism and carried by the'car, Figs. 3 and 4 are detail views oi' parts of the switch mechanism.

In the drawings -The numeralyl designates the main track; 2 the siding; and 3 the pivoted point which is confined in its movement by the strip or rail 4. In, the surface between the rails is sunk the casing or 'box 5 and the larger casing or box 6,' which are connected by the pipe 7, and coupling sleeves 8. In the casing 5 is formed a bracket 9, to which is pivoted at 10, the right vangled shaped lever 11, one arm 10 of which has secured thereto the bracket plate y12, and in openings 13, of the arm and plate r is mounted the pin 14, which projects up through the curved slot 15, in the cover platelG. The pin is provided with a collar 14, against which and the arm lQ, exerts the tension of' a coiled spring this normally forcing the pin upward to project its upper 'end above the slot in the cover plate 16.

To the other arm 10X, of the lever 11, is secured one end 17, of the rod 18 whose other end 19, is secured to the arm 20, of the angle lever 21, fulcrumed at 22, in theA bracket 23, and having its other arm 24` formed near its end with an opening 25, to receive the threaded rod 26. Upon this threaded rod is placed the pair ci nuts 27, which serve to adjust the tension of the pair 'of coiled s Jrings28, which surround the rod 26, and be r at their outer ends against the nuts 27 and at their inner ends .against the opposite faces of the arm 24. The arm thus has a spring orcushion connection with "the threaded rod which prevents injury to the arm or rod and alsopermits the tension of the springs to be adjusted to suit the circumstances. The inner end of said threaded rod is mounted at 29., in the turn buckle 3 0, whose other threaded sleeve 29 receives the threaded end 31 of the pin 32,- which is4 connected at its headed end' 33, to the pivoted switch point. It will thus be seenv that the two cases or boxes are arranged be'tween the rails, sunk in the ground and protected from the' elements by covers and that the pin 14,l

will always be retained above the cover of thecase by the spring.

To operate the switch' from the car we` provide a novel mechanism which we will now describe.

The platform 34, ofthe car is provided with an opening 35, around which is lsecured the guide plates 36, the lower of which is formed with a sleeve 37, and guided in the opening and plates is the plunger 38, hav! ing at its upper end a treadle or foot pin 38 and having its lower endsecured to the yoke shaped frame 39. To the frame 39 and the sleeve 37, are secured the pairs of plates 40, each having a'hook 40', and to the hooks of the series of plates are connected the loops 41 on the pair of coiled springs 41.

It will thus be seen that the plu-nger isforced down by pressure of the foot and upon releaseof the foot the springs instantly raise the plunger with theA yoke shaped frame 39 connected to the' plunger.

To the frame at its lower ends 39 is secured the shoe for operating 'the switch mechanism and th'isshoe is ofpeculiar and novel construction and consists of the pair of oppositely fiared arms 42, and the pair of oppositely fia-red guides or boxes 43, the
