Application filed October 18, 1926. Serial No. 142,399.

My invention relates to certain new and useful improvements in railway switches and more particularly to slide plates, heel plates and turn out plates for supporting the stock rails in an inwardly inclined posltion, and supporting the closure rails and swi ch rails in correct positions relative to the inclined stock rails. 7

It is well known to those familiar with inclined top bearing surfaces are now in general use, the inclined surfaces being so arranged to give the rail an inclination towards the centre of the track, but the rails used in the construction of switches are still carried on flat plates giving no inclination. This causes undue twisting strains on the rails where they leave the inclined plates and are carried on the flat plates, and the rails are not properly supported on the fiat plates for a considerable distance.

My invention is designed to overcome these conditions and to provide switch slide plates to supportthe stock rails with the correct inward inclination, and carry the switch rails in relation thereto: to provide heel plates and turn out plates. for gradually bringing the closure rails to the correct 1nward inclination, and-for carrying the stock rail correctly inclined.

' This construction brings the switch in line with modern practice of inclining the rails, provides suitable plates on which to carry the rails, and obviates any unnecessary strain 35 being put on the rails and makes an improved track layout.

In order that those skilled in the art to which my invention pertains shall know how to make and apply the novel features of-con 4 struction and combination of parts, I will proceed to fully-describe them.

Figure 15 is a plan of Figure 14. I The slide plates Figs. 2 and 4 can be used m on either side of the switch, i. e. for both stock rails and switch rails. but the heel plates and turn out plates must be made right hand and left hand. For convenience plates used on the right hand side of the switch are shown only.

Similar reference numerals indicate like parts in the several figures of the drawings.

In Fig. 1 is indicated a lay-out of a standard railway switch. Outside of the points A. D. the rails are carried on standard inclined tie plates. Between A. and B. all the rails are carried on novel slide plates 2 and 4., which are shown enlarged in Figs. 2. and 4. Between B and C. are located the novel heel plates 7. which are shown enlarged in Fig. 7. and between C. and D. the rails are carried on the novel turnout plates 9, 10. 11. and 12. all shown enlarged in Figs. 9. 10. 11. and 12.

All the tie plates are carried on usual ties, and fastened in the usual manner by spikes or the like. The drawing Fig. 1., is diagrammatic only, and more or less ties and plates may be used for each switch layout.

as may be required.

In Fig. 1. the stock rails 3. 3 are carried in an inwardly inclined position towards the centre of the track throughout, the switch rails5. 5 are carried in a vertical position, and the closure rails 6. 6. join the a switch rails at B. in a vertical position, and are gradually turned over to an inwardly inclined position by means of the plates 9. 10. 11. and 12., until they are same inclinatlon as the stock rails 3. 3

In Figs. 2. and 3. are shown the novel. slide plates 2. on which is supported the stock rails 3. 3 and the switch rails 5. 5 The slide plate 2. is provided with a raised surface 13. on which the base of the switch rails 5. 5. slide, and is so arranged to bring the top of the switch rails 5. 5 slightly above the stock rails 3. 3*. at all points where the switch rails 5. 5 are full height as shown in Fig. 4. at G. An inclined seat 8. is arranged to support the stock rails 3. 3*. at a definite inclination towards the centre of the track, the flange of the stock rails 3. 3. abutagainst the edge 20. of the slide 13., and against a stop 15. integral with the plate 2. an extension 16. is provided to seat a. rail brace 18. whose outer edge abuts against a second stop 17 also integral with the plate 2. The rail brace is held in place by means of spikes 19. which passes through same and holes 19. in the plate 2. Holes 19. are provided for spiking the inside of the plate'2. to the ties, and holes 19. are also provided in a limited numberof plates 2. for spiking the switch rails 5. 5*. against the stock rails.

In Figs. 4. 5. and 6. a slide late 4. is shown which is very similar to p ate 2., but is Without provision for seating a rail brace.

Plate 4. has a raised surface 22. for carrying the switch rails 5. 5*. an inclined seat 21. for supporting the stock rails 3. 3 a stop 23. against which the flange of the stock rails 3. 3. abut. and slots 19. and hole 19". for spiking plate to ties.

Fig. 6. shows a cross section of plates 2.

i and 4. at sections EE. and FF.

7. by means of standard angle bar joint plate 25. and bolts 26. the ends of the switch rails and closure rail being supported in slot 27. cut in plate 7. with a flat seat. Holes 28. are arranged through-the plate 7. for spiking same to ties. The difi'erence in height between the stock rails 3. 3 and the switch and closure rails 5. 5 6. 6 is shown at G. and is the same as in Fig. 4.

As the stock rails and closure rails graduall diverge, and as the heights of these rails are different, and further the closure rails are vertical and must be given an inwardly inclination in conformity with the stock rails I use a series of novel turn out plates, 9. 10. 11. and 12., Figs. 9. 10. 11. and

12. to accomplish this purpose.

It is usual when any rail. is required to be higher than the mean height of track, to run off this extra height gradually over a number of ties, and since the height G. Fig. 7. has 'IOC' to be run off I arranged for this in my novel turn-out plates 9. 10. 11. and 12; Further since the closure rails 6. 6 are vertical over heel plate 7. and at a like inward inclination at D. to the stock rails 3. 3*. I also arrange my novel turn out plates 9. 10. 11. 12. withinside seats of varying inclinations to make this change gradually over a number of plates, and although for convenience I have chosen four plates, I may use a reater or lesser number as may best suit varlous types of switches.

In Fig. 9. the novel arranged with a slot 29. having an inclined seat of suflicient width to just fit the base of the stock rails 3. 3F. and hold them in an inwardly inclined position, and of such in-' clination to line up with'the inclined seats of the slide plates 2. and 4. and heel plates 7 and a second slot 30 having an inclined seat seat of suflicient width to just fit the base of stock rails 3. 3 and hold them in an turn-out plate 9. is i inwardly inclined position equal to the inclination of plates 2. 4. 7. 9. and a second slot- 32. having an inclined seat of just sufiicient width to fit the base of closure rails 6. 6 the difference in height between the stock rails and closure rails G being one-half G. in Fig. 7. and the rate of inclination of the seat of slot 32. is one-half the inclination of seat 31.

In Fig. 11. the novel turn-out plate 11. is arranged with a slot 33. similar to and having the same inclination and purpose as slots 29. and 31., Figs. '9. and 10. and a' second slot 34. similar to and having the same pur os as slots 30. and 32. Figs. 9. 10. but w1th the difference in height G one quarter G. Fig. 7. and the rate of'inclination of slot 34. three quarters theinclination'of slot 33.

In Fig. 12. the novel turn-out is arranged with two slots of equal height and inclination, the slot 35. carrying the stock rails, 3. 3 and the slot 36. carrying the closure rails 6. 6 the inclinations being equal to the inclinations of slots 29. 31. 33. Figs. 9. 10. 11.

Fig. 13. is a plan of Fig. 12. and shows slot 36. on an angle with slot 35., the holes 37 are arranged for track spikes for fastening the plates to the ties. Fig. 13. also serves as a plan for Figs, v9. 10.11. except that the distance between the two slots vary for each plate 9.10. 11.

In Figs. 14. and 15. is shown an alterna-' tive type of novel slide plate in which the .stock rails 3. 3. are sup orted. on an inclined seat 40. with the inside rail base edge abutting against the edge 43.,of raised sli e 39. The inclined seat a0. ends at a stop41. integral with the plate 14. which abuts against a rail brace 38 and holds same against lateral movement. S ike holes are arranged at 42, for fastening t e plate to the ties. The base of the rails 5f. slide f on slide 39.
