SWITCH-THROWING- DEVICE.

Specification of Letters Patent.

Patented Apr. 9, 1912.

Application filed June 30, 1911. Serial No. 636,159.

To all whom it may concern:

Be it known that I, JOSEPH MoLNAR, a subject of the King of Hungary, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Switch-Throwing Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a switch throwing device, designed for-switches for street railways.

My invention aims to provide, first, a device that can be readily installed upon the present type of street cars and in connec tion with the present type of switch by simply changing two of therails adjacent to said switch; second, a switch throwing device that is positive in its action, free from injury by ordinary use, and easy to manipulate; third, a track equipment that is not susceptible to operation by vehicle traffic; fourth, a car equipment that occupies a comparatively small place and is inexpensive to manufacture. With this understanding of the principal objects of my invention, reference will now be had to the v drawings, wherein like numerals denote corresponding parts throughout the several views; wherein Figure 1 is a plan of the track equipment; Fig. 2 is a side elevation ofthe same,

showing a portion of a car above the same;

Fig. 3 is a side elevation of the car equipment; Fig. 4 is a longitudinal vertical sec tion of a portion of the same; Fig. 5 is a front elevation of part of the car equipment, and Fig. 6 is a cross-sectional view of a portionof the car equipment.

The reference numerals 1 and 2 denote ties or sleepers supporting rails 3 and 4 and switch frogs 5 and 6, the latter having a movable switch tongue 7. Extending through the transverse openings 8 .in the frog 6 is a transverse rod 9 connected to the tongue 7 by. nuts 10. The ends of the rod 9 are pivotally connected by pins 11' to bell crank levers 12 and 13, pivotally mounted by pins 14 upon the tie 2, located beneath the switch frogs 5 and 6.

The bell crank lever 12 is connected by a coiled retractile spring 15 to a bracket 16, mounted upon the tie 1 adjacent to the tie 2, and pivotally connected to the bell crank lever 12 by a pin 17 is a connecting rod 18. The connecting rod 18 is pivotally connected by a pin 19 to an actuating member 20. This member is pivotally mounted upon the other tie 2, by a pin 21, and extends through an opening 22 provided therefor in the enlarged portion 23 of a rail 4. The opening 22 is in communication with a longitudinal groove 24 formed in the enlargement 23 of a rail 4. The ends of the groove 24 gradually merge into the ordinary groove of the tread of the rail 4.

The bell crank lever 13 is connected by a coiled retractile spring 25 to a bracket 26 upon the tie 1 adjacent to the tie 2 of the switch frogs. The bell crank lever 13 is connected by pin 27 to a connecting rod 28, and said rod is pivotally connected by a pin 29 to an actuating member 30 located upon tie 2, supporting the member 20. The member 30 is similar to the member 20 and extends into the rail 3, which is similar to the rail 4.

The car equipment comprises two depending brackets 31, carried by the platform 32 of a car; these brackets, being positioned directly above the rails 3 and 4 of the track. Movably arranged in said brackets are rods 33, having the lower ends thereof provided with bearings 34 for rollers 35. Encircling the rods 33 are coiled retractile springs 36, having the upper convolutions thereof connected to said rods, and the lower convolutions thereof resting upon the brackets 31. The upper ends of the rods 33 have heads 37 provided with transverse pins 38. The upper ends of the rods extend through openings 39 in the platform 32, and the heads 37 are located between guides 40, carried by housings 41 mounted upon the platform 32.

Journaled transversely of the housings 41 are rook shafts, and mounted upon each shaft within the upper part of the housing are cranks 43 adapted to engage under the ends of the pin 38. The outer ends of the rock shaft 42 have depending cranks 44. The cranks 44 are connected by a stirrup 45,

and said stirrup is connected by a coiled retract-ile spring 46 to a. bracket 47 mounted upon the platform 32. Arranged upon the platform 32 in front of each of the housings 4]. are bearings 48 and a post 49, and arranged in the bearings 48 is a rock shaft 50 provided. with cranks 51, connected to the cranks 44 by reach rods 52. The rock shaft 50 has another crank 53 connected by a link 54 to the end of a lever 55 fulcrumed in the upper end of the post 49. The free end of the lever 55 has a handle 56 adapted to be engaged by a catch or hook 57 of a conventional form, the catch or hook being carried by the post 49, and adapted to hold the handle end of the lever in a lowered position.

Assuming that a car is moving in the direction of the arrow A of Fig. 1, and it is desired to pass on to the siding track which necessitates the opening of the switch tongue 7, the motorman or operator of the car releases the lever 55 at the right hand side of the car; when the lever is released, the tension of the spring 46 is sufficient to rock the shaft 42 and lower the arms 43, therby releasing the head 37 of the rod 33. The spring 36 immediately lowers the rod and places the wheel or roller 35 in the groove of the rail 3. As this wheel engages the contact member 30, said member is moved, and through the medium of the elements 28, 13, and 9, the switch tongue 8 is opened. Besides these elements being actuated, the

elements

12, 18, and 20 are shifted, the member 20 extending into the groove of a rail 4, whereby the car equipment can be actuated at the left hand side of the car to restore the switch tongue to its normal position. The

springs 15 and 25 are employed and arranged to retain the members 20 and in adjusted position. After the car has passed on to the siding track, the lever 55 can be moved to raise the arms 43 and elevate the rod 33, said rod being retained in an elevated position by securing the lever 55 to the post 4:9 by the catch 57 hat I claim is In a switch throwing device, a track equipment comprising a switch tongue, grooved rails, actuating members pivotally mounted adjacent to said rails and adapted to extend in the grooves thereof, a rod connected to said switch tongue, spring held pivoted bell crank levers pivotally connected to said rod and adapted to be moved by said members, and a car equipment, including rods adapted to be released to place the lower ends thereof in position to engage said actuating members.

In testimony whereof I afiix my signature in the presence of two witnesses.
