Description
GEORG-n W. HARRIS AND .GEORGE ELLIOT, 0F AURORA, INDIANA.
Letters .Patent No.` 69,912, datei October 15, i867.
IMPRov'BD RAILROAD caossINe.
TO'WHOM IT vMAY CONCERN:
A ABe it known` that we, GEORGE W. HARRIS and GEORGE ELLIOT, both of Aurora, Dearborn county, Indiana, have invented a new and useful improvement in Railroad Crossings; and we hereby declare the following to be a full, clear,and exact description thereof, reference being had to theaccompanying drawings, making part of this specification. l
Our invention relatesto a construction of the rails at a crossing our intersection of two tracks, which, -while fully as eiicient and4 durable' as the customary .frog, is cheaper in its construction, and more easily hrepairedtor replaced, whether. in whole or part.
The accompanying drawing is a perspective'view of a. railroad crossing embodying our improvement. The top of each rail-A`designed to form part of an'intersection has formed in i't, by swaging orV rolling while in thelheated condition, a gain or depression, B, at distance from the end of the rail corresponding tov `iiange track of crossing train. This gain B, being formed by swaging,.cau`ses a lip or bulge, C, which pret seves the proper transfrersev areaof the rail, and makes it as strong at the gain as at any other: part. The
portions of the rails which are impinged upon bythe crossing train are of steel. Knees D are bolted to the intersecting' rails on their outer Asides in the manner represented. AThe opening B for the opposite wheel ange is provid-edby allowing a suitable gap or distance to intervene between th'e rail end and the side of the intersecting rail .in each case.' The rails thus-arranged may be secured to suitable cross-ties inthe customary manner.
A great advantage of our arrangement consists in the removability Afor repair or substitution of any part of one track without disturbance of anyothr part or of the intersecting track at all, whereas the common frog, if deficient in any part, requires to be taken up bodily, so as to throw both' tracks out of use. By our 'mode of construction a track-layer can lay downas much in oneda'y as formerly required a week, arrd with a corresponding reddction of expense.
We claim herein as -new, and of our inventon- 1.- A railroad crossing, formed b'y prolonging two rails of each track in opposite directions beyond the intersecting rails, andhaving gains B and gaps B', as and forlthe. purpose set forth.
' 2.,.In combination with such gained and intersecting rails we claim the knees D, applied as herein made known. l
` In testimony of which invention we hereunto set our hands.
G. W. HARRISf GEORGE ELLIOT.
