ERNEST NAGFEL, OF COLUMBUS, OHIO RAILWAY cnossrno Application filed June 15),

This invention relates to railway crossings and has for its object to provide, ina manner as hereinafter set forth, a crossing'ofthe class referred to including courses of composite,

z armored slabs and ineans associated with the slabs of the courses to prevent the slabs from heaving or becoming dislocated.

' A further obj ect of the invention is to provide, in a manner as hereinafter set forth, a railroad crossing including courses of composite, armored slabsand interengaging interlocking means at the oppo sed ends of the slabs of each course for holding the slabs down, and ,with said means so constructed and arranged to prevent the corroding thereof whereby the crossing can be readily removed for track maintenance when desired.

A further object of the invention is to provide, in a manner as hereinafter set forth, a composite, armored slab for railway crossings and with the slab including a concrete body and a metallic plate egitendii ngentirely over the upper face of the body and turned down at its edges, and with the plate having inherent parts thereof .extended'downwardly and embedded in the concrete body, and by this arrangement there is provided a wearing surface at the entire top of the slab, .but further there will be developed a beam strength $9 in the slab which is equal or superior to rein forcing bars forthe concrete body.

A further object of the invention is to provide, in a manner as hereinafter set forth, a coinposite, armored slab for railway crossings so formed that it is capable ofbeing used to pave diagonal crossings and fill in. around the crossing frogs, diamonds, etc. i

A further object of the inventionis to provide, in a manner as hereinafter set forth,a composita arniored slab for railway crossings and with the slab including a concrete body and a metallic reinforcing orarnioring plate, the concrete body being the under supw port forthe plate. The slab is capable of be ing used to pave diagonal crossings and fill inaround the crossing frogs, dianionds, etc, by sifnply cutting the late upon diagonal lines and to conforn ithe concrete body to/the shape of the plate. In the case ofall metal crossings the cost of an undersupport of rose. Serial No. 452,335.

steel such special shapes is extremely high, whereby by setting up' a crossing slab" in the manner as referred to, it is inaterially less expensive than settin up the slab with an in der support of steel n a special shape.

Further objects of the invention'are to provide, in a manner as hereinafter setforth, a railway crossing whichis' simple in its con:- strnction and arrangement, strong, durable, compact, expeditiously removed when occa slon requires, thoroughly efficient in its use, readily installed an comparatively inexpen sive to manufactiire; With the foregoing and other objects in View the inventionconsists'pf the novel construction,combination and arrangement of parts as hereinafter niore specifically" described, and illustrated in'the accompanying drawings; wherein is shownan embodiment of the .invention, but it is to he understood that changes, variations and modifications can be resortedto which fall within theiscope ofthe claims hereunto appended.

Figure 3. is a transverse sectional viewof a railway crossing'in accordance with this invention as applied to a track. y

Figure 4 is a frag'ni entary view in top plan of an armor plate forming an element of the slab. I

Figure'h is a section on line 5 5', Figure 4. Figure 6 is a section on line 6 6, Figure 4. A railway crossing in accordance withthis invention will be set up oflconrses of c oin- O posit-e, r ored slabs. A set of sidewise opposed abutting courses willbe positioned between the pair of track rails upoii the supporting ties forthe latter' and an .outercour'se positioned exteriorly of each traclilrail upon the projecting ends'of therail'tiesor sleepers. The end slabsof each course will be slightly different in form with respect to the interinediatejsla b or slabs of the courses. Figure l illustratesone end slab and one inter1iiediate slab of a course and which are indicated generally at 1, 2 respectively. The slabs of each course are arranged in endwise opposed, abutting relation. The drawings illustrate by way of example, longitudinally disposed courses of slabs, or rather courses disposed lengthwise with respect to the track. The outer courses of the set of courses are arranged in sidewise opposed abutting relation with respect to the sides of the intermediate course or courses of said set. WVhen a plurality of intermediate courses form part of the set they are arranged in sidewise opposed abutting relation. The drawings illustrate, by way of example, the set of courses as consisting of a pair of outer courses and one intermediate course. Each slab is armored by a steel plate extending throughout the upper surface of the body portion of the slab. The body portion of the slab is constructed of concrete. The plate which armors the slab can be smooth throughout its upper face or roughened or corrugated or provided with spaced, upstanding protuberances and further having inherent parts thereof for anchoring it to the concrete body. The courses of the set of courses are designated A, B and C and the pair of outer courses at D and E.

The spaced ties or sleepers of a railway track are indicated at 3 and the track rails at 4, 5. The

rails

4, 5 are secured to the ties 3 by the spikes 6. The ties project laterally from the

rails

4, 5 as at 4, 5', and upon the former are mounted courses D and upon the latter courses E. Flangeways 7, 8 are positioned against the inner sides of the

rails

4, 5 respectively. Filler members 9, 10 are positioned against the outer sides of the

track rails

4, 5 respectively. The fiangeways and fillers extend lengthwise of the track rails and are preferably constructed of oak. Each flangeway is formed with a set of spaced sockets 11 which open at the inner side thereof. Each filler is formed with a set of spaced sockets 12 which open at the outer sides of the filler. The

rails

4, 5 are mounted on chair plates 13. The courses D and E oppose the filling members 9, 10 re spectively. The courses A, C oppose the flangeways 7, 8 respectively.

The number of the slabs of each of the courses will correspond and the end slabs 1 of each course comprise a concrete body 14 having its upper surface at its outer end bevelled downwardly to the free edge of such end as at 15. Each end slab l of each course is formed with a plurality of spaced, V shaped notches 16 for the passage of spikes 17 to secure the slabs to the ties or sleepers 3. The spikes 17 also act to prevent the longitudinal shifting of the courses with respect to the ties or sleepers 3.

Each end slab 1 of each course has its concrete body armored by a metallic plate 18 which completely covers the upper surface of the concrete body and is formed with downturned flanges 19 at its sides and ends. The flanges have the edges thereof seated against shoulders 20, 20 formed respectively on the sides and ends of the concrete body. The shoulders 20, 20 are arranged above the center of the sides and edges of the concrete body. The inner faces of the body of the plate 18 and flanges is snugly engaged throughout by the concrete body. The outer faces of the flanges 19 are flush with the side and end faces of the concrete body below the shoulders 20.

The end slabs 1 of the courses A, B and C have each side thereof, below shoulder 20 provided with spaced sockets 21 which register with certain of the sockets 11 and mounted in said registering sockets are dowel pins 22 for connecting said slabs to the fiangeways 7, 8.

Each end slab 1 of each of the courses has its inner end, below the inner end shoulder 20 provided with spaced socket-s 23 for a purpose to be presently referred to.

Each intermediate slab 2 of each course comprises a concrete body 24 which is armored throughout its upper face by a metallic plate 25 having downturned flanges 26 at its sides and ends which seat upon shoulders 27 formed on the side and end faces of the body 24 below the top of the latter. Each slab 2 has each of its ends provided with spaced sockets as at 28, 29. If each course is formed with but one slab 2 the sockets 28 register with the sockets 23 of one end slab and the sockets 29 with the sockets 23 of the other end slab. If each course is formed with two or more slabs 2, the

sockets

28, 29 of a slab 2 will register with

sockets

28, 29 of an adjacent slab or slabs 2 and with the sockets 23 of slabs 1. Dowel pins 30 are mounted in the registering sockets for coupling the slabs together.

The intermediate slab or slabs 2 of the courses A and B have their outer side faces provided with spaced sockets 31 registering with certain of the sockets 11 and mounted in registering

sockets

11, 31 are dowel pins 32 for connecting slabs 2 of courses A and B to the fiangeways 7, 8. The

sockets

28, 29 and 31 are arranged below the flanges 26.

The inner side of each of the

slabs

1, 2 of the courses D and E, below the inner side flanges of the armoring plates is formed with spaced sockets 32 which register with the T sockets 12. Mounted in the registering

sockets

12, 32 are dowel pins 33 for connecting the slabs of courses D and E to the filler members 9, 10.

The dowel pins hold the slabs down and i "at in pbsition certain of the concrete body portions abut each otherand abut theflange' ways'an'd certain of the" flanges abut each otherandthe flangewaysl g V I When the" slabs of the'courses D and E are in position the concrete body portions and certain-of thefianges thereof abut each other and the concrete bo'd'yportions and certain pfthe inner side flanges abutv the filler mem- 'JGIS. c

Pfe ferably the armoring plate forming an element of each slab will be provided with anchoring means therefor, and such means will be inherent parts of the plate. Preferably the armoring; platewill be formed with upstanding protuberances; i

The" preferred form of armoring plate is illustrate-din Figures 4, 5 and'6, The body of the plate is indicated at 35 and the flanges atf87. The'body 35 is formed with lengthwiserows of spaced, tapered, hollow protuberances 38having flattened tops 39. The length of the protuberances is materially greater than the width thereof. The protuberance's of one row ale staggered with respect to the protuberances' of an ad acent row, The'flat'top's of the protuberances provide tread surfaces. Thebo-dy 35 isfurther formed'with depending tongues 40 providing inherent'anchoring meansfor the plate. The

tongues40 are arranged in staggered rela tion'with respect to each'other'. The tongues are positioned between pairs. of protuberancesj38'of the several rows. The tongues are provided by slitting the body 35 and bending inwardly the material freed by the slit. Each tongue" gradually decreases in Widthfrom its point of joinder with the body 35 to its free end; Eachtongue isof slightly greater length than a protuberance, and is formed with a flat, elongated intermediate portion 41, an inclined end portion 42 and an end portion 43 formed of rearwardly directed inclined part 44 which terminates in a vertical part L-Sdisposedina plane rearwardlyof and'in spaced relation to the plane of portion 41. The part es merges into the portion 4 1. The portion 42 and part i5 incline in opposite directions, the former toward the point of joinder of the tongue body 35 and the latter toward the part The part 44" is positioned substantially in alignment with thepoint' of jo-inder of the tongue with body 35. The shape of the tongue provides" for the anchoring thereof inthe concrete body portionor under'supportfor the plate Pref-v erably the slabs are of a height slightly less than the height of the'trackrails'.

The upper corners of each of the armoring plates are rounded. The tongues not only anchorthe plates to the concrete body portion or undersupport for the plates, but also act as a reinforcingmeans for such body. As the p1ttes o1i1p1ete1 envelope the upper part of theconcrete body the life 'of thelat ter is materially entranced. KS the are arranged staggeredly with respect to each'jother they are anchored at spacedpoint s toth'e concrete body. i What I claim is I 1.
