IMPOVED RAILWAY-CROSSINGS.

ZIO ALL WHOM- IT MAY CONGERN:
Be it known' that I, STANHOPE PERKINS, of Fairfield, in the county of Lancaster, England, have invented an Improvement in the Manufacture of Railway-Crossings 5 and I do hereby declare that the following is a. full and exact description ot' my said invention.
This invention relates to a novel mode of manufacturing the point or V-aail of railway-crossings, the obje'ct being to increase their structural strength. To this end I take a rolled double-headed steel rail, or other section of steel rail, and, having pla-ned off a certain portion of the iianges on one side thereof, I double back the rail upon itself to bring the plancd surfaces into contact, and I thus form the nose'of the point-rail out cfa double thickness of' the web of the rail. The side of ythe rail, at the partwhere it is tobefcreased or doubled backI first indent by a smart blow, and I then set the rail so that the portion of the flanges required to be removed may be cut away by a planing-tool. I next heat-,thc rail in the centre and bend it back, and close the parts on an, anvil until the plnned surfaces meet with cach other., I thus leavefthe nose of the point or V-rail solid, which is very important, as the blow of the wheel is most felt at that part. I then drill through both of the Webs, or parts in contact-,and rivet or bolt them together, as the case may be. The outer flanges are cut away at the nose and tapered oil for a short distance, in the usual way, to give the proper shape to the point-rail. In the accompanying drawingi Figure 1 is a plan 'of the improved crossing complete. W W'are the wing-rails, and V is the rail forming the crossin gov-point. A, B, C, and D arc the chairs for sustaining the several parts of the crossing.
Figure 2 is a side vi'ew of the crossing complete.
` Figure 3 is a longitudinal section of the crossing complete, showing `the end of ,the V-piece in"l section.
Figure 4 is a transverse section of the crossingimmediately in front vof the nose of the V-piece, showing in elevation the chair C and the V-piece, and thcwing-rails in section.
Figures 5 and 6 are plans of the doubleheaded rail set and the inside edge plancd preliminary to bending. The amount of metal planed oi is indicated in both these iignrcs by the red lines.
Figure 7 shows thc V-rail bent to a rghtangle. When the points marked Gr G (which indicate the'limits of the planed surface) are brought together, the rail formsthe required angle or V-part of the crossing. The length of the plancd surface from G G to nose will vary according to the sizeof angle or V-.point required.4
The chairs lmarked B und C are shown on the drawing as bol-ted, but they may be sccuredwth wood keys, I
preferred.
- I would here remark that some of Vthe advantages of crossings made on this plan, are, that they can be readily and economically made by planing or-shaping-machines. If made of rolled steel rails they are as durable asienst-stecl crossings, and can be supplied at much less cost than any of the patented east-steel or iron crossings, and they are safer and .make a. better and more uniform road, and the crossing or'V-pont can be made to iit the O chair perfectly, and is also reversible.
Havingnow explained the nature of my invention, I wish it to be understood that I claim- Forming thc points or V-parts of crossings, without splice, by bending the rail, prepared as'aboi'e described,
back upon itself, and securing the abutting parts in the manner and 'for tbepurpos'cahove set forth.
In witness whereof, I, the said STnNnorn IEnnms, have hereunto set my hand and seal, this tenth day o f August, in the year ci' our Lord 'one thousand eight hundred and sixtyseven.
