CAST-METAL CROSSING.

SPECIFICATION forming part of Letters Patent No. 391,961, dated October 30, 1888.

Application filed May 15, ISES. 4Serial No. 273,935. (No model.)

To all whom, it) may concern.-

Be it known that l, GEORGE PENAL-iu GRA- HAM, of South Chicago, in the county of Cook and State of Illinois, have invented certain new and usel'ul Improvements in CastMetal Crossings, and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to cast-metal railwaycrossings, or means employed at the intersection of railway-tracks for securing together the track-rails.

The invention consists in the novel details ol construction herein shown, described, and more particularly pointed out :in the claims.

ln the accompanying drawings, illustrating my invention, Figure l is a plan view of my novel railroad-crossi ng, illustrating the several rails in posit-ion. Fig. 2 is a vertical sectional view of the same, taken upon line 2 2 of Fig. l, looking in the direction shown by the arrows.

In said drawings, A is a liat plate or soleplate of cast metal, preferably steel,having the usual projections or arms, A', and adapted to be placed under the meeting ends of four trackrails at the point where the latterintersect each other. Said arms A A are shown in the drawings as arranged at right angles with each other, but in cases where the rails cross obliquely the arms will of course be correspondingl y inclined. Cast integral with the arms A of said sole-plate and extending upward to the full height of rails placed nponthe sole-plate are vertical iianges or (as they are sometimes called) wing-rails"7 B B.

C C are horizontal extensions or fillings cast integral with the flanges B B and having their lower surfaces separate from and above the adjacent upper surface of the sole-plate A, so as to leave grooves or openings c @,extending inwardly beneath said tillings,as clearly shown in the sectional view, Fig. 2.

D D are the adjacent ends of two rails arranged in alignment with each other, and D2 Diare adjacent ends of two other rails arranged in alignment with each other at right angles to the rails D D. The ends of said rails D D' D2 D: rest upon the arms A A of the sole-plate A, with the ilanges of the rails within the grooves c c and the webs d d ol' the rails in contact with the fillings C C. In the particular construction illustrated the ends of the rails D andDare separated a sufficient space to give passage to the wheel-flanges, while the rail Dwhich is at right angles with and adjacent to the rail D', abuts against the end of the latter, the end of the rail D3 being separated from the adjacent side margin of the rail D in the manner illustrated.

The several langesBB, in connection with the rails arranged as above describcd,form continuous horizontal grooves for the wheeltlanges, which grooves cross each other at the middle of the sole-plate in the manner shown in the drawings. The fillings C C ot' course form the bottoms of said grooves, the fillings being made continuous or integral at the intersection ofthe said flanged groovesin amanner readily understood.

The outer surfaces of the several flanges B B are preferably vertical and flat-,except at their lower portions, at which points they are provided with small iillets b b. The faces or margins C' of the fillings C C which come in contact with the webs of the rails are rounded at their upper and lower corners to closely fit against the said webs between the tread and rlange of the rail in the manner clearly shown in Fig. 2.

The rails are secured to the casting, made as above described,by means of horizontal bolts E E, passing through the webs of the rails and through openings b in the said wing-rail B.

In operation the cast sole-plate A is lirst placed in position at a railroad-crossing and bolted or spiked securely to the ties, it being of course understood that four of said plates are commonly used for one crossing. The tread-rails D D' D2 D3 are then severally secured in place and bolted to the Iianges B B, as above described. It will be observed that the flange or wing-rail B acts asa guard for the anges of the wheels, but at the same time receives no bearing therefrom nor any jars from the wheels, and their entire load is borne directly by the tread rails D and the flat horizontal portion of the sole plate A,which rests, as above mentioned, upon the ties or sleepers. It will thus be seen that when the rails become worn, as they very quickly do at this particular place upon a railroad-bed, they may be IOO easily removed by removing the bolts E E and anew rail placed in position.

I am aware that steel or other cast metal has been used heretofore in the construction of 1ailroad-crossings;.but I do not believe and do not know thatacast-steel crossing with a guardrail and filling cast integral therewith have ever been used forthis purpose. I have shown the extensions A of the soleplate A at right angles with each other; but itis obvious that these extensions may be placed at any angle to form switches or Ys in aroadbed,as is well understood by all railroad men.

I claim as my invention-` l. The cast-metal railwayorossing consisting of a fiat sole-plate provided with four angularly-disposed vertical ilanges or guard-rails casti ntegral therewith,sai d guard-rails having lateral extensions or fillings extending partially over said soleplate, said fianges and extensions being provided with substantially horizontal bolt holes, substantially as described. ff

2. A east-metal railway-crossing consisting of a dat sole-plate provided with four angularly-dispose'd. vertical flanges or guard rails cast integral therewith, said guard-rails having lateral extensions or fillings sufficiently below the top edge of the guard-rail to clear the wheel-Harige, and said fillings being cast oontinuous at the center of the crossing, substantially as described.

3. The combination, with a castmetal railway-crossing consisting of a tlat sole-plate and four angularly-disposed vertical flanges or guard-rails cast integral therewith, said guardrails being provided with lateral extensions, of tread-rails resting upon said sole-plate and bolted to the guard-rails, substantially as described.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.
