RAILWAY SWITCH.

Application filed August 14 1919.

To all aw/r0212 it may concern:

Be it known that I, OREM Jonnax, a citizen of the United States, residing at Free dom, in the county ot Beaver and State 01" Pennsylvania,have invented certain new and useilul Improvements in Railway Switches, o l which the following is a snecification.

My invention relates to new and useful improvements in railway switches, the primary object 0t which is to provide a means which will guide the movement of the train when passing through switches thus pre venting the splittingor picking of switch points, which frequently causes the deraih ment of trains.

A further object 01 my invention is to provide a means of the above mentioned cha 'acter which will be actuated. into and out of operative position by the movement of the switch lever.

A further object of my invention is to provide a means of the above mentioned character which may be attached to the switch of the ordinary' structure without materially altering the same.

A further object of my invention is to provide a means of the above mentioned character which issnnple in cpnstructioin easy to operate, reliable in such operation, and inexpensive to manufacture.

Other objects and advantages of this invention will be apparent during the course of the following description.

In the accompanying drawings forming a part oi? this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1, is a perspective plan view showing my improvement attached. to a switch;

Fig. 2, is a transverse sectional view of my improvement, and

Fig. 3, a perspective view of the base block with the guard member removed In the drawings, wherein for the purpose of illustration, 1 have shown a preferred embodiment of my invention, the numerals 5 and 6 designate the rails of the main track, while 7 and 8 designate the rails of a side track. The sectional portion 9 ot the rail extends toward but terminates short of the rail 6. as does the rail 7 terminate short of the rail 5. Pivotally connected to the terminals oi. the ails 7 and 9 are switch pieces 10 and 11, which have their tips or Specification of Letters Patent.

points arranged to engage the respective rails 5 and tin the usual manner. These rails are supported by the usualtics l2.

Arranged transversely oi the track and connected to the underside of the switch pieces 10 and ll is a switch throwing bar 13. This bar has its free end bii'u *cated as at ll to pivotally receive the hand lever 15 pivoted to the plate 15, as at 17. A plate 16 ot' a substantial rectangular shape having at each end an up-turned lug 18 connected to the ends of the ties '12, as shown at 18, is "provided with an inwardly projecting tongue 19. formed intermediate its ends.

A. base block 20, placed between the rails and extending longitudinally thereof is provided with flanges 21 which overlap the top of the ties and are secured thereto as shown at 22. This block is located in close relation to the jointure oi the side track with the main track. At thecenter and extend ing transversely of the block is a "i"-shaped recess 23, the head of which is adjacent the rail ("3. The sides 24 oi the stem ot this recess are grooved as at :25, the said grtmves being curved upwardly. Slidaltily mounted within this recess is a guard member 26 of a shape similar to the recess. The outer edge of the guard member is arcnate in shape as shown at 27, the purpose oi? wl'uich is to be described later. Projecting from the sides of the movable member are laterally extending pins 28 adapted to slide in the grooves 25. thus directing the transverse movement ot' the member 26. Adjacent the forward end of the underside of the mem ber 26 is a downwardly projecting lug 2. shaped to snugly fit within the opening 30 formed in the recess The inner edge of the opening 30 is beveled as at 30, to taciliinto the removal oi the lug therefrom. The purpose of the lug is to normally prevent transverse movement of the member 26 when the switch is in an open position. a

The bell crank lever has a long and short arm, the long arm being pivotally connected to the upper side of the tongue 19, midway its length. by the pivot pin The free end of the long arm is provided with a link 33, which pivotally connects the lever with the switch throwi 'ig bar 15 as shown. at 34.

The rear end of the uard member 326 has projecting downwardly therefrom a U shaped staple 35 to receive the eyelet 36,

formed on one end of the reach rod 37. This reach rod extends transversely beneath the block'20 in a groove 38 provided for that purpose. the reach rod and bell crank lever is bifur cated at one end to pivotally receive one end of the reach rod as shown at 40. The opposite end of the link is pivotally secured in the bifurcated portion 41 of the short arm of the bell crank lever. Accordingly, the guard member 26 is connected to the switch lever 15 in such a manner that its actuating movement 1S governed thereby.

In operation when the switch is open, as shown in Fig. 1, the guard men'iber 26 is in a position so that the ar mate shaped end 27 is adjacent the main rail track 6. As is obvious, when a train approaches to enter the switch, the. weight of the train is thrown against the movable point 10, of the rail 7,

which frequently causes the splitting or.

' picking of the point. owing to the thinness of the point at its jointur'e with the main rail In using my improvement this accident is prevented, since the wheels on the oppositesi'de of the train traveling on rail 6 will contact with the arcuate shaped end 27 of the guard member 26, thus holding the flanges of the wheels on track 5 out of contact with the point 10, and at the same time divert the course of the train so, that the train will pass through the switch without splitting or picking the points. To close the switch, the switch points lO-and 11 are oscillated by throwing the hand lever 15 backward, which in turn rocks the bell crank lever 31 through the medium of the link 33,

thus exerting pressure upon the rod 37.

The pressure on the rod 37 pulls the guard inember'backward, which is elevated in its transverse movement by the pins 28 sliding in the curved -grooves25. \Vhen in this position, the guard member will not in any way interfere with the movement of the train passing on the maintrack.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that certain changes in the shape, sizeand arrangement of parts may be resorted to without departing from the spirit of the invention or the scopeof the sub joined claims.

Having thus fully described my invention, I claim 1. In a switch, the combination of a main track, a siding, a base block, a guard member movable transversely on said block, a switch throwing mechanism. and means associated with said guard member, whereby the same is actuated through movement of the switch.

2.

A rail-point guard comprising a transversely grooved base block, a guard member slidable in said groove, means for retaining the member in a rigid position, and means for actuating the guard.

6. In a switch, the combination of a main track, a siding, a transversely grooved base block, a guard movable in said groove, means for locking the member in an operative position, a switch throwing mechanism, and

means joining the guard and switch mecha msm.

8. In a switch, the combination of a main track. a siding, a transversely grooved base block, a guard member slidable through the groove, having means for guiding its movement, means for retaining the guard in an operative position, a switch mechanism, and

means for joining the guard and switch mechanism whereby the same are operated simultaneously.

9. In a switch, the combination of a main track, a siding, a base block, a T shaped the block, a correspondingly shaped guard member slidable in said groove, pins projeetin from the member for movement in slots 0 the groove, means for retaining the member in an op.- erative position, a switch mechanism, and a series of levers joining the guard with the switch mechanism whereby the same are operated simultaneously.

10. In a switch, the combination of a main track having a siding associated therewith, a base block'adjacent the jointure of the siding with the main track, a T shaped groove extending transversely across said block, a correspondingly shaped guard member movable in said groove, means for retaining said guard member in an operative position, a
