Application filed January 15, 1912. Serial No. 671,277.

To all whom it may concern:

- Be it known that I, VINczn Sziios, a subject of the King of Hungary, residing at Barber-ton, in the county of Summitand State of Ohio, 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, and the objects of my invention are to provide simple and effective means, as will be hereinafter set forth, whereby a switch can be thrown without resorting to the use of a switch barand without the operator of a car leaving the same to throw the switch, and further, to provide a switch throwing device that can be advantageously used in connection with suburban railways.

Other objects of my invention are to provide a switchthrc wing device that is positive in its action, not liable to injury by ordinary use and highly etficient for the purposes for which it is intended.

My invention aims to obviate the necessity of 'motormen and conductors stopping a car, leaving the same and throwing a switch tongue, thereby losing time in connection with a schedule. Furthermore, the invention obviates the necessity of employing a regular switchman and eliminates such accidents that occur by neglect upon the part of a switchman and the loss of -ro'llin stock and lives. The switch throwing device has been designed whereby it can be used in connection with the present type of rails and it can be readily adapted to steam railways by similarly equipping locomotives.

- Withthis understanding of the principal objects of m invention, reference willnow, be had to tie drawings, wherein like nu-' merals denote corresponding parts throughout the several views, in which Figure l'is a plan of the switch throwing device, showin the main track clear, Fig. 2 is a longitu inal sectional view taken on the line 11-1-1 of Fig. 1, Fig. 3 is an enlarged cross sectional view taken on the line TIL-111 of Fig. 1, Fig. 4 is a similar view taken on the line TV-IV of Fig. 1 Fig. 5 is a similar view taken on the line VV of Fig. 1-, and Figs. 6 and 7 are detail perspective views of parts of the switch throwing device.

The reference numerals 1, 2, 3, 4 and 5 denote some of the ties supporting main ails 6, 7 and 8, siding rails 9 and 10, and ibivoted switch tongues 11 and 12, said switch tongues being movably connected to the ends of the rails 8 and 9, and the siding rail 10 merging into the main rail 7. The rails 6 and 7 constitute a main track and the rails 9 and 10 a siding track.

The switch tongues 11 and 12 have the confronting sides thereof connected by a rack bar 18 having a rack 14. Engaging the rack 14 is a sector gear 15, carried by a sleeve 16, mounted upon the end of a rock shaft 17. One end of the rock shaft 17 is journaled in a bearin 18, carried by the tie 4 and the opposite en% in a bearing 19, carried by a plate 20 secured to the ties 1, said plate being located a suflicient distance from the switch tonguesll and 12 in'order that said tongues can be thrown or shifted prior to rollin stock passing over the same.

The p ate 20 is provided with an opening 21 and mounted upon the shaft 17,- within said opening, is a crank 22. Engaging the crank 22 is an actuating member 23 pivotally mounted between apertured lugs 24, carried by the plate 20. A coiled compression sprin 25 is interposed between the member 23 an the plate 20-for retaining the actuating member 23 normally elevated.

A car or other rolling stock approaching the switch in the direction of the arrow A is equipped with a shoe (not shown) that is placed in engagement with the actuating member 23 to depress the same and throw the switch tongues whereby the car or rolling stock can pass on the siding track. The device carried by the car or rolling stock forms no part of this invention and any suitable device can be employed.

The switch tongues 11 and 12 are connected by a bar 26 and this bar extends over straps 27 and 27 connecting the ties 9. and

.3. The straps 27 and 27 have a longitudinal guide rod 28 between'the ties 2 and 3, said guide rod having one end thereof connected to the strap 27, as at 29. Loosely engaging the guide rod 28, between the straps 27 and 27 is a depending apertured lug 30,

carried by the bar 26, and encircling the guide rod 28. Between the lug 30 and the strap 27 is a coiled compression spring31,

said spring retaining the switch tongue. 12 normally in engagement with the rail 10 and the switch open with the main track clear.

36, secured to the ties 5. The plate 36 is provided with a pivoted spring supported actuating member 37 for engaging acrank 38, carried by the shaft 33, said actuating member being similar to the member 23, but

reversed relatively to said member.- The rock shaft 34 has the opposite end thereof journaled in a bearing 39, carried by the plate 20, said rock shaft having a crank 40 to be engagd by a spring supported actuating member 41 pivotally mounted upon the plate 20. The actuating member 41 1s similar to the 'member 23 and arranged the same. The inner ends of the shafts 33 and 34 are provided with hook-shaped cranks 42 normally engaging a transverse pin '43, car- I ried by a locking member 44 having a tooth 45. The locking member 44 is carried by a rock shaft 46 journaled in bearings 32,

said rock shaft having a crank 47. Interposed between the crank 47 and the tie 2 1s a coiled compression spring 48. The con necting bar 26 has a notch 49 to receive the tooth 45 of the locking member 44. As the switch tongues 11 and 12 are shiftedby the actuating member 23, the connecting bar'26 is moved to position the notch 49 under the tooth 45 and the tension of the spring 48 immediately rocks the shaft 46 and places the tooth 45 in the notch 49, thereby locking the connecting bar 26 and preventing the switch tongues 11 and 12 from being accidentally displaced. The rocking of the shaft 46 to lock the connecting bar 26 also rocks the shafts 33 and 35, elevating the cranks 38 and 40'of said shafts.

Should a car or rolling stock approach in the direction of thearrow Aand desire to continue upon the main track, the member 41 isactuated, which rocks the shaft 34, elevates the in 43, looking member 44, rocks the she 46 and moves the tooth-45 out of engagement with the connecting bar 26, allowing the tension of the spring 31 to shift the tongues 11 and 12, whereby the car or rolling stock can continue upon the main track. Should a car or rolling stock approach upon the side track'in the direction of 'the arrow B and find the switch closed, as shown in Fig. 1, the member 37 is actuated to rock the shaft 33 and perform the same operation as that described in connection with the member 41.

From the foregoing" it will be observed that I have devised a novel switch throwing device for saving time and repair in.con-

shaft, a sector-gear carried by one end thereof and engaging said rack bar, a crank mounted upon the oppositeend of saidrock' shaft, a pivoted spring supported-actuating member for engaging said crank, rocking said shaft and moving said switch tongues, a bar connecting said switch tongues, and means including a rock shaft and lockin member for locking said bar to hold, sai

switch tongues adjusted position. 2. In a switch throwing evice, bmation with a main track, and a siding track, of normally open switch tongues conthe com 3 trolling the passage of rolling stock at the junction of said tracks, a rack bar connecting said switch tongues, a longitudinal rock shaft, a sector gear carried by one end there of and engagingv said rack bar, a crank mounted upon the opposite end of said rock shaft, a pivoted spring supported actuating member for engaging said crank, rocking said shaft and moving said "switch tongues, a bar connecting said switch tongues, means includin a'rock shaft and locking member for locking said bar to hold said switch tongues in adjusted position, and means ineluding independent rock shafts and actuating members for releasing the first mentioned means whereby said switch tongues can be restored to normal position. Q

3. In a switch throwing-device, the comblnation with a main track, and a siding track, of normally .open switch tongues con-" trolling the passage of rolling stock at the unction of said tracks,a'ra'ck bar connecting said switch tongues, a longitudinal rock shaft, a sector gear carried by one end thereof and engaging said rack bar, a' crank -mounted upon the opposite end of said rock shaft, a pivoted spring supported actuating member for engaging said crank, rocking said shaft and moving. said switch tongues,
