IMPROVEMENT IN RAILROAD RAILS.
Specification forming part of Letters Patent No. 136,043, dated February i8,4 1873.
To all whom itmay concern:
Be it known that We, A. B. DEAN and THOMAS C. COLEMAN, of Louisville, in the county of J eierson and State of Kentucky, have invented a new and valuable Improvement-in Railroad Rails; and we do hereby declare that the following is a full, clear, and exact 1 description ofthe construction and operation of the same, reference being had to the annexed Adrawing making a part of this specification, and to the letters and iigures of reference marked thereon. A
Figure l ofthe drawing is a representation of a perspective view of our rail. Fig. 2 is a sectional view of the same, showing attachmentto sleeper.
This invention has relation to railroad rails; and it consists in the novel construction of the rail, whereby it is provided with an inner downwardly extending or vertical bearingtlan ge, and an outer horizontal fastening flange, the tread being above and between the llanges, as hereinafter described.
The object ofthe present invention is to provide a rail with an extension bearing-surface which will resist the tendency to curl upward in the vertical direction; the weight of metal being economized to compare favorably with rails of other form now in use. 4
The general form of this rail may be described as Fshaped. It\donsists of rib or body A of considerable thickness, somewhat rectangular in cross sectibn, extending' upward, and rounded suitabliy at its upper edges to form the tread of the rail. l The inner face B of the rail is vertical, or nearly so, and is continuous with the inner face of ,the vertical flange C, which extends downwardfrom the inner portion lof the body A throughout the length of the rail. The outer face D of this flange extends obliquely upward and outward to the middle portion of the base of the body of the rail. The base of the rail is extended outward by the broad horizontal iian ge E, which extends outwardv from the lower` p0rtion of the lbody of the rail. This flange is perforated. obliquely at suitable Vpoints F for the passage of the fastening-spikes H. These perforations are situated in the curved an gular surface G of the outer face of the rail'body, where itjoins the horizontal ange, so that the head of the spike will be in close contact with the metal of the rail on both sides when driven obliquely and inwardly, in the manner indicated in the drawing.
The rails above described may be laid upon stringers for street railroads, or immediately on the cross-ties, the latter being properly notched for the reception of the vertical flan ge or stem of each rail.
Thel advantages of this rail are as follows: Its form issuch that it is not liable to spread. It has a very large bearingsurface compared with the weight of the rail. flange keeps the treadA in its position, prevent-- ing lateral deviation, and at the same time strengthens the rail to resist the upward cnrl` ing or the formation of snake-heads. There are no obstructions on the inner side of the rail inthe shape of spike-heads or other fastening devices, the rails being secured by the spikes passing through the outer or horizontal flange. The fasteningspike acts in connectionwith the vertical flan ge or stem of the rail as a clamp, securing the rail to the stringeror tie in a very durable manner. The position of the stem immediately under the inner or tread portion of the body of the rail gives it great strength and rmness to resist the weight of the heaviest vrolling-stock.
What we claim as our invention, and desire to secure by Letters Patent, is-
The railroad rail, consisting of the body A forming the tread, the inner vertical tapering ange O, and. the outer horizontal iiange E, all constructed and arranged as` specified.
In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
