RAILROAD-CROSSING.

SPECIFICATION arming part of Letters raten; No. 698,206, dated April 22, 1902.

intersection of the rails Awi-thopenings for the` passage of the wheel-fiangcs. These openings are wide enough to cause a heavy jar upon the rolling-stock, rails, and foundation of the crossing, and the ends ofthe rails become granulated and brittle, thus necessitating frequent repairs and increasing the cost of maintenance. The present invention seeks to overcome these defects and for this purpose provides a simple andeffectiveconstruc-' tion by which a continuous trackV may be formed in either direction and which may be operated directly or in connection with the usual interlocking switch mechanism, gate,or the like. Preferably, also, automatic means are provided whereby ,the crossing may be operated by an approaching train.

In the construction of the invention I have sought to do away with the use of bolts, nuts',`

` pins, Washers, and the like, which when used ,to connect moving 'parts soon wear andbe'-v come loose, by which I am enabled to emf ploy a simple and effective construction which will be durable in operation and in which the cost of maintenance is reduced to a minimum.

The invention consists in the features set forth in the following description, illustrated inthe accompanying drawings, and more par-l ticularly pointed out in the appended claims.

In the drawings, Figure-1 is a plan view of myimproved crossing with the mechanism on one side of the same shown in detail. Fig. 1a Vis-a"` detail view in elevation of a part o f the automatic operating mechanism. Fig. 1b isa detail'sectional view on line 1b 1b of Fig. 1a.

' Fig. v2'isa Vview in vertical section of the improved crossing, taken on the line 2 2 of Fig. 1.V Fig. 2B- is a view similar to Fig. 2 with themovable cross-rails shown in their lower position. Fig. 2b is a view in vertical section Serial No. 66,323. (No model.) l i taken mi the une t b of Figi i. Fig. 2G15 a detail plan view of a part of the operating mechanism. Figs. 3 and 3 are detail plan kviews of parts of the'crossng.

The crossing may be mounted upon asuitable framework of Wood or steel, but is preferably mounted upon a base-plate 10,of steel, which is preferably anchored to a cement foundation, with a thin interposed sheet of rubber backing it. The base-plate is provided With lthe upwardlyprojecting abutments-1l, secured to or formed in piece with the base-plate and to which are fastened the abutting ends of the main rails 12, which form the intersecting tracks. Between the ends of the main rails 12 and between the abutments 11 extend the oppositely-disposed pairs of tie-railsl3, which are secured to the base-plate 10 and which are provided withlthe shouldered portions 14, whereon the inner ends ofthe main rails 12 are .mountedyas most-clearly shown in Fig. 2b. The tie-rails Vare arranged with their upper edges level with tlie tops of the main rails and slightly out of line therewith, as shown in Fig. 1, but in positionto partially support a train as it passes over'the crossing, and are provided with the openings or passages 15 at .their ends for the wheel-flanges. By this construction the parts of the crossing are all rigidly connected togeth'er, will not be displaced by contraction `and expansion under varying temperatures, `and will readilyv withstand the shock and jar inner side. Such means preferably consist of the center plate or block 17, of steel, mounted upon the horizontal supports 18, which are interposed between the edges of the center plate and the base-plate 10. The plates 10 and 17 and the supports 18 are preferably rigidly secured together by suitable'bolts. The

four sides.

cross-rails 16 are provided at theirlower edges with the inwardly-projecting flanges 19,which by engaging with the edges of the center plate 17 serve to limit the upward movement of the cross-rails and retain the same in place. The outer lower edges of the cross-rails are slightly beveled, as shown in Figs. 2 and 2a. These cross-rails are preferably formed of an ordinary rail-section, in which the depressed sides are filled up with the longitudinal strips 20, firmly bolted to the body of the section and with the portion of the lower outer flange cut off, as shown in Figs. 2 and 2, The tie-rails 13 may be similarly constructed, if desired.

Oppositely-disposed pairs of reciprocating shifters or wedges 21 are mounted to slide upon the base-plate and beneath the crossrails 16 for raising the latter. These wedges are provided with the forwardly-projecting prongs, preferablythree in number and preferably of considerable width. These prongs are provided at their forward ends with the inclined portions 22 for engaging the lower beveled edge of the cross-rails and have horizontal upper bearing-surfaces, whereon the cross-rails rest when in raised position and so that the cross-rails are rigidly supported in such position. The prongs of the wedges pass through suitably-arran ged openings in the tierails 13 and in the supports 18, as most clearly shown in Fig. 2b. Each wedge or shifter 21 of one pair is connected to the adjacent wedges of the other pair by means of thebell-crank levers 23, which are mounted to swing in a horizontal plane upon the upwardly-projecting studs 24, secured to the base-plate 10, and which are provided with the circular-headed ends 25, engaging the circular notches 26 in the sides of the wedges or shifters 21. The bellcranks are preferably slipped over the upwardly-projecting studs 24, so as to swing over the upper face of the base-plate 10. The ends of the bellvcrank levers pass beneath the ends of the main rails 12 into engagement with the notches 20 of the Shifters. By this means the wedges or Shifters are so connected that when one oppositely-disposed pair of cross-rails is moved inwardly the other pair is 4moved outwardly and so that when one oppositely-disposed pair of cross-rails is raised to form a continuous track in one direction, as shown in Fig. 2, the other pair of crossrails will drop into their lower position, as shown in Fig. 2, and will not interfere with the wheel-flanges of the train passing over the continuous track.

Each of the shifting-wedges is provided with a horizon tally-disposed operating-rod 27, rigidly secured at one end to the wedges and extending along between the rails of each track on each side of the crossing. In Fig. 1 the operating mechanism is shown only on one side of the crossing; but it will be understood that the construction of such operating mechanism is the same on each of the The operating-rod 27 is provided near its end with a downwardly-projecting stud 28, which engages a slot in the end of a lever 29. The lever 29 is preferably mounted to swing about a stud 30, secured upon a bent plate 3l, which is mounted between two of the ties, as shown in Fig. l and in the detail View Fig.,2. The lever 29 may be connected in the well-known manner to the switch-tower usually located at such crossings and, if desired, may be connected with the safety interlocking switch mechanism, so as to be operated simultaneously therewith, or the lever could be connected to the gates or other devices employed at such a crossing. Preferably, also, at least one of the other operating-rods 27 is also provided with a similar lever, so that in setting the crossing to form a continuous track in either direction the crossing will be operated by direct pulls on all parts of the operating mechanism, thus avoiding all danger of buckling of the parts.

Means are also provided so that the crossing will be operated by a train approaching in any direction. For this purpose a pair 0f longitudinal bars 32 are secured to the ties outside of the main rails 12 of the track on each track of the crossing. These bars are preferably provided with downwardly-projecting ears 33 between the ties. Cross-shafts 34 are provided, having shouldered ends journaled within the ears of the bars 32. Upwardly-extending rock-arms 35 are mounted upon either end of the shafts 34 and extend upwardly between the bars 32 and the main rails l2. Rocking bars 36 are arranged against the outer sides of' the main rails 12 and are provided with laterally-projecting studs 37, which are engaged by the upper ends ofthe rocking arms 35. A pair of levers 38 and 39 are mounted to swing upon studs 40, mounted upon a horizontal bent plate 41, secured in position between the ties adjacent the end of the operating-rod 27. The lever 38 is provided on`its inner end with a circular head, which interlocks with a cir cular notch in the lever 39. The lever 38 is also provided ,on its inner end with an upwardly-projecting stud 42, engaging a hole inthe end of the operating-rod 27, and the outer ends of the levers 38 and 39 have upturned ears, as shown, which are connected to the rocking bars 36 by the links 43. By this means if the crossing is not properly set for an approaching train the wheels thereof will engage the rocking bars 36, rock the latterdownwardly and horizontal1y,and thereby operate the crossing through the medium of the levers 38 and 39 and operating-rod 27 to properly set the crossing to form a continuous track in the direction in which the train is approaching. It will be understood that all four sides of the crossing are provided with automatic operating mechanism, so that the crossing will be properly actuated byatrain approachingin anydirection. Preferably the operating mechanism is inclosed so ICO IIO

as to be protected from the weather by a sheet-iron casing 44, secured to the ties in any suitable manner. (See Figs. l and 2b.)

It will be observed that none of the operating parts are secured together by bolts and nuts and that the use of connecting-pins, washers, and the like,which are apt to quickly wear loose, is avoided.. The operating-shifters for the cross-rails of each track are positively connected, so that the crossing is certain and safe in operation, and a continuous vtrack will be formed in one direction only.

The parts are so mounted upon the base-plate 10 that by removing the ends of the main rails l2 and the center plate 17, the parts may be removed and repairedv by an entirely new set in a very short space of time without delaying the traffic, and means are provided for positively operating the crossing by direct pulls in connection with the interlocking switches, together with automatically-operatin g means, so that safety and certaintyfof operation are assured. The mechanism could be applied to a vnumber of tracks crossing one another and could be easily modified to suit any angle of intersection.

It is obvious that the details of construction could be varied by the skill of the mechanic without departure from the essentials of the invention.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-
