RAlLWAY-FROG FQR TURN-INS AND TURNOUTS.

Patented Feb. 20, 1906.

Application filed August 24,1905. Serial No, 275,611. 1

To all whom it may concern.-

Be it 'known that I, EDMUND M. RANKIN, a citizen of the United'States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Railway-Frog for Turn-Ins and Turnouts, of which the following is a specification.

My invention has for its object the prevention of all crushing and mashin of the points of rails in railway-frogs, and t ereby avoiding the formation of depressions in the track which each successive car-wheel in the operation of the road makes larger.

It is' also an object of my invention to do away with the necessity of renewing railroad-frogs on account of ordinary wear, also to prevent the noise attendant upon the passing of frogs by a railroad-car, and also to prevent the jar transmitted to the car on passing over a frog. t is an object of against pounding of hollow-tread wheels on railwayoints at turn-ins and turnouts and elsewhere-that is to sa when the tread of a oar-wheel becomes ho lowed or worn next the flange by travel the outer ed e of the tread thereof is liable to pound ont e points and ends of the rails or fro and at the ]0lI1tS. I propose to avoid this difficulty by simple means.

To these ends my invention comprises a chilled-steel plate, whichI prefer tocall a riser, attached to the frog inthepath of flanges ard armor su aces or risers bridging1 surfaces the. w

the car-wheel flan e and ada ted 5 its shape to raise the trea of the w eels s ightly. oflt' the frog or rail points'or 'unctions, so that the car may have-a smoot passage overthe fro without touching the oints. he invention is applica le forall kinds of' frogs-as, for instance, whole frogs, half frogs, double frogs, spraddle-frogls, and mate 'frogsgso e of which will be erein illustrate 'An object of this invention is to avoid the destruction to whichsuchfrogs have heretofore been. liable and to rovide means where-' by the life of railwayogs may be renewed indefinitely. p

v I propose to take advantage of the-fact that the flanges of railway-cars are hard and strong and to provide at the rail-junction in the fro s and 1n the ath of the car-wheel the space alonide the notches, on w feel-flanges will roll, gently this invention to provide the notches and oints an it after the note es and points have been assed. The rise and fall of the wheel need e only suflicient to insure against the tread of the wheel sinking as it passes the notches, the principle being to so construct the fro s as to support the wheel by its flange whfie passing thenotch.

The accompanying drawings illustrate the invention. a i

Figure 1 is a plan view of a-.double-li ne railroad-crossing with turn-ins and turnouts and illustrating wide and narrow gage roads provided with my frog. Fig. 2 1s a detail perspective view of .a fro provided with a og-riser. Fig. 3 is a detai perspective view of an outside user in place at a joint between two rails, fragments of which are shown. Fig. 4 is a section online w r, Fig. 1, with a fragment of a wheel. Fig. 5 is 'a section raising the wheel sufficiently to carr it over gently owering lengthwise of one of the risers and fillers,

showing a ortion of the frog in elevation. Line x in Fig. 1 indicates the ine of section. Fig. 6 is a section on line a) m, Fig. 1, with fragment of hollow-tread wheel thereon.

In the drawings I have shown a turn-in and turnout at a junction of a double-track railroad, showing both narrow and standard gage tracks. In the turn-in and turnout thus formed there are whole frogs W, double fro s D, spraddle-frogs S, and mate frogs M, -wit risers R laced in each of them and each made of a stee plate chilled and riveted down by-rivets r to what is called a filler F in each frog, so that the flanges of the car-wheels will run on-the risers for the pur ose of raising the vwheels of thecars over a 'points and "notches in said frogs, said Wheels rolling on their flanges on the risers while passin through said'frogs going in on an incline an -coming out on a decline at-the ends '5 and d of the risers; I

The risers are put down .on iron plate foundations I and riveted" down to said founda- At the points P and to of the risers therefor'will in practice be onehalf inch below the level of the top'of the main loo rail, the risersbeing inclined at each end, thereb causing the tread of the wheels torise gradua ly above all points "and notches that are to bfin protected and going of]? with a gradual dec e wheels in place while passing over-the frogs There are guard rails G for holding the IIO shapes, length's and sizes to meet the re-' not be forced so far into the frog as to,neces-,

the point of the section. AuXiliary riser 11 on the risers, and there are guard-rails opp'oi site all frogs.

Spraddle-frogs S and risers R are located where a broad-gage track leaves the narrowi gage track. In the drawings whole-frog risers are marked R, double-frog risers are l markedR, spraddle-frog risers are marked R and mate-frog risers R i The fillers F are constructed to rest on flanges 4 of the rails, respectively, asshown more particularly inFig. 2, and the risers may be made to fit underneath the tread 50f the rail. On the ends of the risers R are the 5 inclined and declined portions i and d, which serve to gradually raise and lower the wheels Q J, which, pass over the respective frogs. I I The risers are provided on their outsides i with guard-flanges 7, which are flared outward at their outer ends, as at 8. In the, plan view these flanges are in some places 1 shown as a continuation of the customary guard-rails, where such continuation is convenient, j

The risers R are made in such shape in ground plan as to fit the respective frogs for which they are intended, and thus, as will be seen from Fig. 1, the risers may be of various uirements of the respective frogs, The risers of different forms are indicated by the character It with an exponent.

In' assing over the frogs the flanges of the car-w eels run onto the risers and are gradually lifted by the inclined portion of the riser until the treads of the wheels are clear of the rails and are held in this position until the frog around which this particular riser is laced is passed, when the wheelis gradually et down by the declined portion (1 on the further end of the riser.

Riser R is placed in Fig. 1 at the frog caused by the crossing of wide gage rails b and narrow-gage rails c. On the outside of the frog is placed the helper or auxiliary riser I-I, upon which the tread of the Wheels assing over such frogbear in case such whee s hap pen to be hollow, as, at J, Fig. 6. A section 10 of rail 0 is connected with the main por-' tion of rail 0 by a second auxiliary riser 11. Section 10 forms an ,adjustment for frog (1, around which riser R is placed, so, that'the points" at rail-junction 12 of section 10 need sitate wheels'passing over the frogjamming verges over thefgap 13betweensec'tion 1 0 and main rail 6. I have shown but one frog.

equippedwith the adjustingEsectiOn and auxiliary risers; but other frogs which are of a shape to allow of such provision may be provided with such adjustment also.

In general I have shown risers in connection only with frogs on theoutside rails, and in ordinary practice they-will be used on that rail only on account of the difficulty of placing the risers inside the guard-rails 14, attached to the inside of the rails; but I do not limit myself to risers secured to and operating on the outside rail, as they are just as applicable to the inside as the outside rails.

The risers may be ap lied in frogs now in use, as well as in other rogs. To apply the invention to frogs now in use, the risers will i be made of appropriate shapes and applied to their appropriate frogs, respectively, whereupon the workman will drill rivet-holes ,t through the risers, fillers, rail-flanges, and foundation, and then drive rivets 1' into place. To. remove the risers, the rivets Wlll be driven down through the rivet-holes, thus releasing the detachable risers, whereupon they may be replaced with new ones having rivetholes drilled to correspond to those of the detached worn riser.

The joint 13 between a main rail 0 and a frog-section 10 is desirably made with a space, as indicated in Fig. 3, to take u the expan sion, and, in such cases the boltoles b in the filler will be oblong, as indicated in Fig. 3.

In Fig, 1 large arrows indicate the direction of car travel on the different tracks.

What I claim is 1., A railway-frog provided with a foundation, a filler and a riser, and with rivet-holes therethrough, and rivets in saidholes detachably fastening the parts together. v

2,. Arailway-frog comprising rail-junctions and rail ends, risers adapted to protect said junctions and ends fastened to the inside of the rails, and an auxiliary riser.fas-' tened to the outside of the rails atthe junction or ends.

3. A railway-frog comprising two inter secting rails, a riser secured at said intersection on the inside of said. rails, an auxiliary riser on the outside of said rails at the intersection thereof, a clearance space being in one of said rails, and an outside riser secured at said clearance-space.
