ave invented new and useful Improvements 1n Railway-Crossovers, of which the following, taken inconnection with the accompanying drawings,

is a full, clear, and exact descrip- This invention relates to certain improve -ments in railway cross overs and refers more particularlyv to the construction and approaches of the frog and also to the mechansm for securing the associate rails and guard rails in position. In this class of devices considerable difficulty is experienced in keeping the various parts of the cross over in permanent position and repair thereby-not only involving considerable expense in maintaming this part of the railway system in perfect and safe wearing order but alsoincreasing the liability of accident particularly in switch yards and other localities where these cross overs are numerous and over which the employees and other pedestrians necessarily travel. These disadvantages are usually due to the creeping of the ties and superposed portions of the cross over resting thereon, and also to the fact that heretofore the fish plates and other arts of the cross over for securing the ra' s in position have been joined together by bolts and nuts which it is well known'soon work loose and unless they are frequently inspected and tightened allow the rails to become displaced thereby causing excessive wear upon the rolling stock and rails and also frequent disasters at these points.

M mam object is to obviate the use of the usua bolts and nuts in securing the rails of' the'system in place by sup orting the rails at the crossover upon suita le bed plates and locking the rails thereto by separate lock bars or retainers heldnto the bed by automatically clenching keys so that the bed plate ma cover and be secured to a series of ties w lo the lock bars or retainers for each rail section may be separately removed or re laced without disturbing the correspon ng lock bars for the other-rails.

. Anotherobject is to enable the rails of the fro and associated guard rails to be easily an quiekly installed and to secure them in such'manner that the pressure of the flanges of the wheels will operate to more firmly secure and hold the locking members and rails held thereby in place.

corrugations adapted to lock with'pl'ojections on the u per face of the bed plate whereby such rai sections and the bed plates will become interlocked against relative endwise movement.

Other objects and uses will be brough out in the following description.

'In the drawin s-Figure 1 is a top plan of a ortion of a rai way cross over showing the r0 and guard rails. Figs. 2-, 3, 4, 5, 6, 7, 8 an 9 are sectional views taken respectively on lines 2-2, 3-3, 4-4, 5-5, 6-6, 7-7, 8-8 and 9-9, Fi 1. Fig. 10 is a top plan of one of the detached bed lates for supporting the meeting ed 'es of t e rail sections in proximity to one o the guard rails, portions of said bed plate bein broken away to show the tapering ways. ig. 11 is a sectional view taken on line 11-1 1 Fig 10 showing the meeting ends of the rails resting upon the bed plate. Figs. 12 and 13 are respectively top plan and sectional views similar to Figs. 10 and 11 showing a modified form of bed plate in which only one sliding block is used.

igs. 14 to 22 inclusive are perspective views of different parts of the frog, Fig. 14 showing the bed plate; Fig. 15 one of the rail sections"; Fig. '16 one of the outer lock bars; Fig.17 one of the longer lock bars; Fig. 18 one of the shorter inner lock bars; Fig. 19 one of the frog point rail sections; Fig. 20 one of the lock bars in front of the frog point; Fi 21 a fish plate, and Fig. 22 one of the rai locks for the tie.

In order to demonstrate the practicability A still further object is to provide for a i lockin sections 8 and 9-.

of m invention I have shown the portion of a ra' way cross over including the frog and associated guard rail to ether with one of the fish plates and a series of tieplates for the rails operating the guard rail and fro The frog comprises essentially. a meta '0. bed plate 1, opposite rail sections 2;.

and 2.', additional rail oint sections 3- and 3', outer lock ars or retainers 4- and 4' for the rail sections 2.- and 2, additional intervening lock bars 5, '6Jand -.7-- for the rail sections 2 and 2" and point bed plate relatlvel to each other.

By looking the ed plates in the manner just described to a series of ties, it is obvious that by embedding such ties in the road-bed the are caused to cover a large surface area WhlOh reduces to a minimum the liability of shifting or creeping of the frog and parts resting thereon endwise. This bed plate -1- is rovided near its outer longitudinal. edges wit opposite lengthwise flanges 12- preferably ormed integral therewith and rising fI0Il1 'itS top face and having their inner adjacent sides formed with le thwise grooves -13- opening toward eac other substantiallycoineident with the top face of. the bed plate 1- for receiving correspond v ing ribs or flanges on the locking members or retainers 4- presently described, said flanges diverging om the intermediate portion of the ed" plate toward the opposite ends thereof, to conform to the angle. at which one track intersects the other at the cross over.

In practice, I preferably-allow the opposite longitudinal edges of the bed plate to extend some distance,laterall beyond the flanges and these marginal e ges are pro vided at'intervals with apertures for receiving. additional fastening members as spikes 14 which are driven therethrough into .the underlyin ties to more securely lock the bed plate an ties against relative movement so that in effect the ties become a portion of the bed plate covering a large area of ground and thereby reducim the habilit of the endwise creeping or s ing of the' 0g to a minimum.

The rail sections 2 and 2 are.

spaced a art in the usual manner and diverge in o poslte directions toward their ends from an intermediate point corresponding to the sides of t divergence ofthe flanges 12 and to the angle at which one track crosses the other,

said rails being of standard form exce t that the under' sides of their heads: are ormed with "lengthwise grooves --15- at opposite e webs, the outer rooves receiving corresponding ribson the fockin members or retainers +4 and --4 whi e the inner grooves are adapted to receive similar ribs on the locking members -5, 6 and 7 hereinafter described, the lower faces of said rail sections .2- and 2 being preferably corrugated transversely at '16 to intermesh with one or more corresponding corru ations 17 on the upper face of the bed pate whereby the rail sections -'-2-- and 2- are locked'to the bed plate against endwise movement thereupon. These rail sections'2 and 2''. referabl minate short of the ends of t e bedp ate to afford ample su port for the point sections 3 at one en and similar support for the ter- I ends of the main rails as a at the opposite end of the bed plate.

The corrugations 17' are located directly under and interlock .with the ends of the rail sections 2 and 2 near their meeting ends with the main rails a, and j are, therefore,v locked with the bed plate at one end only, leaving the remaimng OI'tlODS to expand and contract longitudina the top face of said bed plate. The fmain rails 'a are of standardy upon lengthand, therefore,their'"de cc of expansion and contraction is consi erable and in,

order that they may have a limited expansion and contraction movement on the bed plate, the portions of the rails u which overlap thereupon are 00 sliding blocks -20- which are mova la in longitudinally elongated recesses 21 in the u per side of s a1d plate, said recesses being 0 osed at their ends to limit the movement of the sliding blocks -2 0.

The locking bars 4 and 4-- as best seen in Figs.- 5 to'8 inclusive serve also as spacing bars to hold the rail sections 2 and 2- a fixed distance from their corresponding flanges 12 and are provided at t eir inner upper edges with ribs 22- interlocking wit the outer grooves 15 in the under side of the head of the rail sections 2- and 2 and their outer edges are formed with lengthwise ribs 23 which interfit in the grooves -13.of the flanges 'site sides of t hold the keys firmly in operative (position 391,390 g a 'i B which-the prongs or tines of the bifurcated keys are driven and whereby such prongs are. spread arikart or clenched against oppoe openings in the ed plate to against accidental withdrawal or ment. driven downwardly from the top and that while their upper ends are exposed it is clear that any downward pressure which is brought to bear u i on them will tend to further clench them an thereby more effectively lock the splaceretainer bars 4 and -4 in their adjusted positions to prevent outward displacement or separation of the rail sections 2 and -2. These rail sections are locked a ainst lateral inward movement toward eac other by the locking plates 5-,

--6 and 7 which are arranged end to metal wedges meeting edge to edge substantially midway between the railsections '2 and 2- and are provided at their outer edges with ribs 27- Fig. 4 which fit in the inner grooves in the under sides of the heads of the rail sections 2- and 2- and have their under sides resting upon the base flanges of said rail sections so as to substantially fill the intervening space below the heads of the rails and are held in place by keys 24 which are like those described and are passed through recesses in the meeting faces thereofand also through a ertures in the bed plate where their lower bi urcated ends are clenched or spread by wedge-shaped cross bars 26- similar to those reviously described, it being understood t at all of these keys are provided with heads which are somewhat larger than the apertures or recesses through which they pass so that when their lower ends are clenched by the cross bar 26, their upper ends or heads are engaged by the top face of the locking members to retain the atter in their adjusted positions.

The locking members or retainer bars 4- and. 5 extend some distance beyond the meeting ends of the fail sections 2 and 2' and their corres ending rails a thereby serving the double purpose of fish plates to hold said meeting ends of the rails in alinement with each other without the use of bolts and at the same time allowing the meeting ends of the rails a' to move a slight distance longitudinally relatively thereto under expansion and contraction to which they are susceptible, the retainer bars -4 and 4 serving to hold the rails from spreading while the wedge- It is obvious that these keys are ature changes.

sha ed locking members or retainers 5- per orm a similar function in holding the v rails a fixed distance apart.

The bed plate -1, rail sections -2 and 2- and 3 and 3 together with the locking members or retainer bars -4, 5, -e-, -7, s and 9 constitute what may be termed a railway frog, the rail point sections 3 and '3 resting upon and extending forwardly from the heel of the bed late so that their converging ends merge etween the rearwardly diverging portions of the rail sections 2 and -2 and are held in place by the locking members 6, 7, -8 and 9.

The locking members 6- are formed in two parts, each locked between the one side of the point-of the frog and adjacent rail sections '2 and are locked in place by keys 24 which are similar to and are held in place in substantially the same manner as that described for the previously described keys, that is they are passed through registering apertures in their res ective lockcross bars 26v similar to those previously described. These locking bars 6- substantially fill the spaces between the rail points 3 and 3 and rails 2 and 2 and their forward ends extend some distance beyond the point of the rail sections 3 and 3 where they preferably abut against the heel ends of the wedge-shaped locking members 5 leaving suflicient clearance for slight expansion'under temper- In like manner, the locking members 7 are interposed between the rail point sections 3 and 3- and rail sections -2 and -2+ substantially filling the intervening space and are held in place by bifurcated keys 24, the latter passing through registered openings in the locking members 7. and underlying por- 110 tion of the bed plate wherethey are clenched by wedge-shaped cross bars 26 similar to those previously described.

The locking members -+8 are somewhat similar in construction to the locking mem- 15 bers 4- and 4 and are interlocked with fixed flanges 35- on the bed plate -1 and are also interlocked with grooves in the under side of the heads of the rail sections 3 and 3 and are held in place by keys -24 which are like those described and are interlocked with the bed -8 are formed with lengthwise flanges enterin the grooves in the flanges 35 while t e inner upper edges of said locking members *S- are also formed with lengthwise ribs or flanges which interlock with corresponding grooves in the under side of the heldinpositlonbykeys24-of substantially the same construction as the others previously described, said locking members 9 having their outer upper edges formed with lengthwise ribs which interfit in the correspondin grooves in the under side of the heads '0 the rail oints 3' and 3' while their lower aces bear upon the base flan es of said rail sections.

T e upper faces of the front ortions of the locking members -9 are su stantially coincident with the top faces of the rail sections 2 and 2 so as to form additional bearings for the rim of the wheels in passing over the point while the uplpersur aces of the remaining portions or eels of these locking members 9' are slightly depressed below-the top face of the rail sections -3' and -3 to receive the keys 24 where the latter are protected more or less from contact with the rim of the wheels of the cars in assing over the rails.

In assem ling the parts of this frog, the

base plate --1 is first secured to the ties- -10- by means ofthe fastening members as spikes 11- and 14,-the latter being driven through apertures in the plate into the ties while the spikes 1 1 are preferably driven into the ties and engaged with the outer lon itudinal edges of the plate.

When t e late is firmly secured in place in the manner ust described, the locking members 4 and 4 are interlocked with the outer faces of their respective rail sections -2 and 2 and are then rested upon the bed and moved laterally and outwardlyuntil their flanges -23enter their respective grooves 13 in the flanges -'12 with which they now become interlocked, in

V V which position thekey openings of the locking members 4 and 4'- are registered in the corresponding opening in the base late whereupon the ke s 24 are driven om the top downwar ly through'said registering o enings and their prongs or tines are sprea or clenched against the under side of the bed plate by the wedge-shaped bars 26, the latter being preferabl integral with the metal bed late. After t 's operation is completed, tfie wedge sha ed locking members 5 are inter ocke with the grooves on the under side of the adjacent face of the rails 2-, 2-. and are driven inwardly or toward the point of the frog until their meeting faces are brought intoclose contact as shown in Fig. 1 in which position the key openings formed by the recesses in the adjacent faces of the locking members 7 meeting ends of the rai s ainto alinement with those of the rail sections -2' and 2'- of the frog and together with the outer lockin members 4- and -4- firmly hold the rails against lateral displacementand in fixed relation to eachother and at the same time permits the adjacent ends of the rails a to moveslightly endwise by expansion and contraction due to thermal changes, it being understood that the ends of the rails a which rest upon the plate are interlocked with the sliding plates .20- which permits such endwise movement and it is also to be understood that the adjacent ends of the rail sections .2 and 2-- are similarly interlocked with the fixed corrugations 17 on said plate to lock said rail sections 2 and 2 to the bed plate against relative movement.

' Whenthe rail sections 2 and .2-.

mately so whereupon the key openings 1n the 1 locking members 6 are brought into registration with the corresponding key open- .ings in the bed plate and the keys -24 are then driven from the top downwardly until clenched by the underlying wedge bars in the bed plate. bers 7' are interlocked with the ooves in the under sides of the heads vof t ir respective rail sections 2 and -2 and are secured in place by the keys -24- in substantially the same manner as that described for the other keys 24.

It will thus be seen that the locking members 4-, 5, 6' and 7 and keys 24, serve to firmly lock the rail sections 2-- and -2-- against lateral displacement and in fixed relation to each other.

-The locking members 8 are thus intereir respective rail sections 2 In like manner the locking mem-' fbasefianges at the outer longitudinal edges of t erein'being brought intoregistration with those in. the bed late whereupon the keys lying wedge 24. are driven ownwardlyuntil clenched by .the underlying wedge bars in said bed.

ate. P The rail point sections are now o'sitioned with their outer edges substantia y parallel with anda slight distance from the inner diverging edges of the rail sections 2- and 2'- fter which the wedge-shaped locking members 9 areslidably interlocked with the grooves in the under sides of the heads of therail sections 3 and 3 and are driven toward the point until their meeting'faces come into close contact and their ke o enings are brought into registratlie underlying openings in the bed plate after which thekeys are driven down- I wardly into lace and clenched by the underbars 26 thereby firmly locking the rail points 3- and 3' against inward displacement or rather holding said rail points a fixed distance apart and against the inner faces of the locking members 8 The rail point sections 3. and 3 are allowed to extend some distance beyond the heel of the frog or bed late 1 and in as much as their lower aces are corrua gated,- I provide corrugated tie plates 50 Fig. 22 which are spikedto the adjacent ties some distance beyond the adjacent end of the bed plate so as to add additional resistance to the creeping or endwise movement of the frog. These corrugated plates have their corrugations'meshing with those on the 7 under side of the rail points 3- and 3' and are usually driven laterallybetween the rails and ties and are provided with raised shoulders 51 forming stops to limit the inward movement of the plates when driven into osition, said plates being preferably provi ed with spike openings for the re- 1(pareption of spikes -'11 as best seen in in the installation of these cross overs, the outer rail as 55- of one of the cross over tracks is usually provided with a guard rail 56- associated with the frog' to cause the flange of the wheel. to travel in the proper channels in passing. over said frog and have shown this guard rail as mounted upon a bed plate 5' 7 which is secured to a series of ties by spikes 1 1 and is provided with lengthwise flanges 59- similar to the flanges 12 for receiving looking members or'retainer bars '60.. of similar cross section to the bars 4 and 4 the heads of the ard rail 56 as well as the rail 55- eing provided with grooves on their under sides for the reception of lengthwise flanges on the locking members 60', said with the locking The guard rail -5e is locked at themside of and a. slight distance from the main rail 55- and is additionally held in place by interposed locking members -63 and 64 corresponding respectively to the locking members -6 and 7 said locking members 63- and 64, being secured in place by bifurcated keys 24, which are similar to the other keys 24 and are clenched in place in substantially the same manner.

The rail 5 5- is preferably divided transversely substantially midway between the ends of the plate 57- and the locking members 60 and 63- serve to keep the meeting ends of the rail sections in alinement and also to hold them down upon the bed plate.

One or both of the meeting ends of the rail sections 55 where they rest upon the bed plate may be corrugated to engage similar corrugations upon said bed late in substantially the same manner as escribed for the.

rail sections -a and -2 although one of the meeting ends of the rail 55 may rest upon a sliding corrugated block similar to the corrugated sliding block 20.

In order to further show the a plication of my invention, that is, the bed p ate, locking members and keys for securing the meeting ends of the rail to the ties I have. shown in Fig. 1 a bed plate which underlies the meeting ends of the rails 55 and is secured to the ties 10 by spikes 71 said bed plate 70 being fprovided with lengthwise parallel grooved anges -72 running along its opposite longitudinal edges for receiving the outer longitudinal edges of the locking members or retainers by means of said bed plate to the tie withbolts or nuts thus. permitting the rails to slide endwise limited distances by expansion and contraction under thermal changes.

It will be seen from the foregoing description thatall the parts entering into the installation of the frog, guard rail and fish members being held in place by keys 24- similar'to the other keys -24' wh le the bed plate is provided; with wedge-shaped bars extending across theirkey openings to s read or clench the lower bifurcated ends of plate may be quickly and economically assembled or removed and if one sart should this part of the rai becomeimpaired it may be read y replaced and still permit the use of the other arts which are not impaired thereby enabling Way system to be easily and economically maintained in a safe Wearing condition thus reducing'the liability to accidents to a minimum. Another im ortant advantage is that the locking members between the rails, especially at the oint of the fro avoids to a large extent the ability of em oyees and other edestrians etting their eet wedged or caug 't between t e rails by reason of the fact that in all instances these intervening locking members .are brought up at least to a lane coincident to the underside of the hea s of the rails while the points of the locking members 9 where the danger is greatest are actually brought up to a plane coincident with the top faces of the rails. The main object of the invention as previously stated is to maintain the frog in sections so that the rails may be secured in place Without the use of bolts or nuts while all of the sections ma be readily installed or either of them quic y and easily replaced when impaired.

What I claim is:

1. In a railway, a bed plate having opposite fixed flanges, a rail having a grooved head, flanged retainer bars between the rail .,and flanges and interlocked therewith, and

-ties, a lengthwise ange rigid with the late,
