SWITCH.

Specification of Letters Patent.

Patented Apr. 3t), 1915..

Application filed November 2, 1917. Serial No. 199,910.

I To all whom it may concern:

Be it known that I, JAMES M. PHINOUS, a citizen of the United tates, residing at Pamplin, in the county of Appomattox and State of Virginia, have invented certain new and useful Improvements in Switches, of which the following is a specification.

This invention consists of a switch adapted to connect a side track or branch line to a main line and wherein the main line rail sections are maintained in a continuous state thus avoiding the use of a frog whosepoints are subjected to wear and the use of which causes a gap that permit excessive pounding as the wheels of the vehicle pass over the gap.

One object of the present invention is to provide a switch wherein the main line rail sections are maintained in a substantially continuous state at the crossover.

Another object is to provide a bridging track element which serves to make a substantially continuous joint between the rails of the side track.

Still another object is to provide a frogless switch which has the side track rails slightly elevated at the point where they cross the mainline rail sections, and connect the rail sections with an interposed track element which is adapted to engage with a main line rail and be firmly held in position thereon.

A further object is to provide a track element hingedly mounted on a base plate forming the connecting element and having a rail section on the upper surface and ad jacent one edge, and a rail engaging lug onv the under surface to cooperate with a main line rail section.

Broadly stated the invention comprises a frogless switch'having an element hingedly secured to the base plate, said element being adapted to removably engage with a continuous rail section to complete an interrupted section leading to a side track, the ends of which rail are slightly elevated adjacent the point of abutment, and means for moving the element and the points of the switch.

One practical form of construction and assembly will be described and illustrated in the accompanying drawings, in which Figure 1 is a top plane view of the switch showing the several points of the invention, Fig. 2 is a vertical sectional view through the element that is employed at the cross over, and

Fig. 3 is an enlarged detailed perspective view showing the element in its raised posi- 6 and 'l' are the main line track rail sections.

The rail indicated at 6 is adapted to be curved so that it will be continuous with the side track rail 8.. The main line rail 6 terminates in a switch point indicated at 9. The side track rail 10 terminates adjacent the main rail 6. As shown it is preferably provided with an angular face 11.

Between the main line rails 6 and 7 there, is disposed a continuation 12 of the side track rail 10. This rail has its end adjacent the rail 6 provided with an angular end 13. Thus a gap is formed through which passes the main rail 6. The rail 12 is provided at its other end with a switch point 14:. The two switch points indicated at 9 and 14 may be connected by a bridle bar 15 adapted to hold them in proper spaced relation.

Other bridle bars may be used if desired. The switch points 9 and 14 are so arranged and formed that they may be placed to con tact with the inner surface of either of the rails 6 and 7 When the point 9 lies adj a cent the rail 6 the point 1 L is spaced from the rail 7. Thus traffic passing over the main line rails will not be diverted into or on to the side tracks through the rails 8 and 10. The rails 10 and 12 are preferably elevated a slight distance so that their tread surface is above the tread surface of the rail 6.

One means of maintaining this elevation is by employing a packing strip 16. Any other means may be employed that will effectively hold the rail sections in their proper elevated position. The tie indicated at 5 is preferably longer than the regular length and one end thereof projects sufli ciently to have mounted thereon a bearing box 17. The box may be secured to the tie by any suitable means such as are indicated by the bolts 18.

The tie 56 is adapted to extend between the main line and side track and extend bearing boxes 17 and 19 are preferably placed in alinement so that the crank shaft 20 may be rotatably mounted in the bearings. The box 19. may. be. secured to thetie 56 in any suitable manner.

One end of the crank shaft 20 may be provided with a bent end to form a crank 21. This crank is preferably formed upon the end which projects beyond the box 17. One end of the connecting rod 2% may be formed to rotate on the bearing end of the Qrenk. a d be el theneen by. any Suitable means. The other end of the connectod. 22 may. bep ioa de with a su a l hol to. oip a W t a ro a 1 y means of a niretal enne t e 4,

The. other. end; of. thethrnw bar 23 may be uitably en ecte ith a hrid e -r 15 a ndicat d a '2 This. cennee on. 25 may. e any custemara ypehe. oth r end of the crank shaft 20 here it projects beyond the bearingbox 19. is preferably provided; with an operating lever. indicated t 6, whic e is. Pr v de wi a h ndle 27,

Asshonn he. ever t3c mprisestwo plate portions. lying. in, parallel, planes that are j ined! by a portion angularly disposed with reference to both. spacedportions. One of'the straight portionslis adapted to provide a pinotal connection, 28. with a. throw bar29 including, a link. The other end. of thethrow baris'adapted to have a pivotal connection 30. with, the element 31. The element 31 serves asfasubstitute for. a frog. A baseplate 32 is adapted to extend from beneath the .r ail8. andhaveits other end secured beneath the rail 6.

As shown the plate may be substantially rectangular and; beprovided With the lugs 33: andi'3lf These lugs extend. upwardly from the upper surface'of the plate 32 and they are providedJwith. holes'which are in alinement "with each other. These holes serve to accommodate a pin 35 that is adapted to. pass through each of the lugs andfalso through a lug portion 36. formed integralwiththe element 31. Thus a hinged type of-j oint. is formed for the element 31.

The lugs 33 and 34: are so positionedthat the element 31 is adapted tolie upon the trackrailz6 and between the ends 11 and 13 of the rails 10.and 12. As these ends are angularly formed. as before described the element 31 has its corresponding corners angularly cut. as indicated: at 37 and 38. This is'done so that'when the element 31 lies. upon the rail 6 a substantially continuous joint. is formedbetweentherails 10v and 12'. In. orderto moreeifectually provide for this the upper surface of the element 31 is formed with a' rail section 39. This section 39.Will thus form a treadsurfaceand the Wheels will ride over this point with, v ry itt epounding- In order that theelenient 31 may be properly maintained in its position upon the rail 6 the lug 10 is employed. As shown the lug. is angularly disposedrwith reference to the long-itudinal axis of the element. In other words the axis of the lug a0 approximately corresponds to one of the diagonals of the element 31.

' The lug 40 may be substantially rectangular inform have one of its ends placed adjacent the end 37 as shown in Fig. 3. When the element 31 lies upon the. nail 6 the; s ngt'aceindicated at 11 will lie substantially in contact. with the rail 6. In order to preaide fenhe Passag of h hrow. bar toward. the element 31thc raihS. may be provided with a suitable opening indicated at 12.

When it is desired to. operate the switch he handle 2 o e lever smore which o ate t e. c nk shaf au ing hec nk 1 0, change impos on.andlnone he swi Poi ts.- nd a t e me ime h movement of the lever. 26 will cause, the throw bar 29.,to monetheelem ent 3. When the seyeral devices are, in the position shown in Fig. 1 the element 31 is in place so that a train approaching from the left will pass into the sidetraekupon therails S. and 10. After the train haspassed into this. side track which if desired maybe a siding the lever 26 is operated. in, the reverse direction wh chwill ro ate he elem t 3 en heba e p a e. 32 and placethe. point.- 9. adjacent, the rail 6 and the point l lrwill be removed fr.o1n ,contact. with the rail 7; The main line will: then be, open for, a throughtrafiic.

From the assembly of the several parts as describedit will be seen that the main line track rails are m aintained in. a, substantially conti uous ondi o adjacent. the point or Insteadof the usual method of providing a gap and two points. forming a portion of-the frog, thesepoints have been elii ninated so far, as the mainline is cone ned- The gap that isiorlned betweenthese rails at thepoints is filled inby the element 31 which provides. a. Substantially continuous tread surface for the rails 10 and 12.
