To all w/iofm, it may concern.'

Be it known that I, JOHN WV. THOMAS, a citizen of the United States, Vresiding at Guthrie, in the county of Logan and State of Oklahoma, have invented certain ynew and useful Improvements in Spring-Frogs and Guard-Rails, of which the following is a speciication.

, My invention relates to a combined spring-frog and guard-rail, and my` objects are to provide novel means for retaining the guard-rail a certain distance from the point of the frog, means to limit lateral movement of the spring-rail of the frog, and resilient means to normally hold said springrail in closed position.

(.)ther objects of the invention will hereinafter'appear, and in order that said invention may be fully understood, reference will now be made to the accompanying drawing, in which:

Figure 1 is a plan view ofthe preferred forni of my invention.y Fig. 2`is across section on line II-#II of Fig. 41. Fig. 3 is a cross section on line III-III' of Fig. 1. Fig. 4 is a section on line IV-IV of Fig. 3. Fig. 5 is a detail plan view of the kfrog-point and part of a wing-rail employed in carrying out the invention. Fig. 6 is a plan View of a modified form of the invention.

1 and 2 designate main-line rails, and 3 and 4 designate branch-line rails of thefrog.

5 designates the frog-point which is preferably formed integral with a section 6 of the wing-rail, said section 6 having a reinforcement 7, provided with a shoulderA A8, against one end of which a guard-rail` 9 abuts. The wing-rail consists of section 6 and a section 6, for a purpose which will hereinafter appear.

Guard-rail 9, preferably, has a number of joints 10, so that it may be easily formed and put together, and comprises an intermediate section 11, paralleling rail 1, and curved end sections 12 and 13. Section 12 abuts against one endof the wing-rail section 6a, and sect-ion 13 abuts against the shoulder S on the wing-rail section 6, see Fig. 1. Section 11 of the guard-rail 9 is secured to the main-line rail 1 with bolts 14, which extend through fillers 15 between said rails. Section 6au of the wing-rail is suitablysecured at one end to section 6 and near its opposite end to the main-line rail 2, by bolts 16 extending therethrough and also through the branch-line rail 3;

yl'designates a filler between the main kONE- FOURTH TO CHARLES n G. y

line rail 2 and section 6a, and 18 designates i a filler integral with the frog-point 5 and inlterposed between the main-line rail 2 and the branch-line rail 3.

19v designates a plurality of bolts to secure 4.one end of section 13 to the adjacent- `end of the wing-rail section 6. v

v20 designates a spring-rail, one end of which abuts against one of kthe main- line 4,22 at kits ends with the rail 20, andsecured at its central portion to the wing-rail by one of the bolts 19. The frog-point 5 is prevented from springing upward above the surface of the adjacent rails by a retaining-plate 23 and a supporting-member 24. Retain'- ing-plate 23 is secured to the spring-rail base by bolts 25, and extends beneath said spring-rail, the frog-point 5, and the wingrail. The supporting-member 24 is suitablysecured to the underside of the frog-point 5. The anges on the wheels of a car passing in either direction over the branch-line will force the spring-rail 2O away from vthe frogpoint5 to permit said flanges to pass, and this lateral movement of the spring-rail 20 is limited by a member 26 extending beneath vsection`13 of the guard-rail 9, t-he wing-rail,

26 to allow for the lateral movementr of,

spring-rail 2O necessary to letthe flanges pass. When the flanges of the car-wheels pass out of engagement with the spring-rail 20, the same is restored to normal position through its own resilience and that of spring 21. Member 26 is held-in proper relation to thebase of section 13 by means of a supporting-member 29, suitably-securedto the underside of said base.

30 designates a guard-rail adjacent the branch-line rail 4, to which it is secured by bolts 31, extending therethrough; fillers 32 being interposed between said rails to coact with the bolts 31 in holding said rails in proper relation to each other. The branchline rail l and the guard-rail 30 are held in proper relation to the branch-line rail 3 and the frog-point 5, by a pair of spacing-members 33, one of which is secured at its ends to the branch- line rails 3 and 4 by spikes 34, While the other is secured at its ends to the branch-line rail 4 and section 12 of the guard-rail 9 by spikes 35. The upper surface of the spacing-members 33 have serrations S6 adjacent the guard-rail 30 to receive the serrated lower ends of a pair of braces 37, which abut against said guardrail 30 and prevents the same from moving toward the branch-line rail 3 and the frogpoint 5. Rail braces 37 have longitudinal slots 38 through Which bolts 39 extend, to secure said rail braces to the spacing-members 33, the slots permitting adjustment of the braces into engagement with the guardrail 30. The interlocking serrations on the spacing-members 3G and the braces 37 prevent movement of the latter on the former after the bolts 39 have been tightened.

By reinforcing the Wing-rail section 6 at a point opposite the frog-point 5, the upper surface of said frog-point is relieved, to a large extent of Wear by the broad surface offered by said Wing-rail section and its reinforcement 7. By forming the frogpoint and the Wing-rail section 6 integral with each other, and separate from the adjacent rails, said frog-point and Wing-rail section may be made of manganese steel or other metal that is harder than that usually employed for the other rails, and consequently the life of said frog-point 5 and the Wing-rail section 6 may be greatly prolonged. 'lhis is also true of the guard-rail section 1l.

In the modified form disclosed by Fig. 6, the spring-rail 20 is dispensed With and a guard-rail substituted therefor'. Referring in detail to said modified form la and 2f* designate main-line rails, and 3a and La designate branch-line rails. 5a designates a frog-point arranged at the intersection of rails 2a and 3a. Frog-point 5au is, preferably, formed integral With sections 6b of the guard-rails 9a, which sections are reinforced at 7a to protect the frog-point 5Z1 from undue Wear. The frog-point 5a and the sections 6" are formed, preferably, of manganese steel to prolong the life thereof. Guardrails 9a have a plurality of joints l0a to facilitate their manufacture and placing in position for use, and their sections 11a are preferably, made of manganese steel.

Having thus described my invention, What l claim and desire to secure by Letters Patent, is:

l. n a device of the character described, in combination, a frog-point, and a Wingrail consisting of a plurality of sections, one of said sections paralleling one side of and formed integral With the frog-point, and having a reinforcement opposite the reduced end of said frog-point for the purpose described.

2. In a device of the character described, in combination, a frog-point, a spring-rail at one side of said frog-point, a Wing-rail cast integral With the opposite side of the frog-point and having a reinforcement With a shoulder, main-line rails communicating With the frog-point and the spring-rail, and a guard-rail having a portion paralleling one of the main-line rails'and curved terminals, one of Which abuts against one end of the Wing-rail and the other against the shoulder at the opposite end of said Wingrail.

In testimony whereof I aiiiX my signature, in the presence of tivo Witnesses.
