RAILWAY-TIE PLATE AND METHOD OF MAKING SAME.
SPECIFICATION forming part of Letters Patent No. 514,467, dated February 13, 1894.
Application filed June 2, 1893. Serial No. 476,869. (No model.)
To all'whom it may concern.-
Be it known that I, WILLIAM W. HOLMES, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Railway-Tie Plates and Methods of Making the Same; and I hereby declare the following to be a full, clear, and exact description of the same, reference being IO had to the accompanying drawings,in which- Figure 1 is a perspective view of a railway tie-plate embodying my invention. Fig. 2 is a perspective view of a blank for forming the tie-plate as produced-by the first step in the [5 method of manufacture, and Fig. 3is a perspective view of the blank after the second and before the final step of manufacture.
Like symbols refer to like parts wherever they occur.
The object of my invention is the cheap and rapid production of an eihcient wrought metal tie-plate having on one face ribs or flanges which are adapted to enter a railwaytie parallel with the fiber thereof, and on the z 5 opposite face ribs or abutments at right angles to the first named ribs or flanges and adapted to form abutment-s for the foot flange of a rail.
ear-plates, or tie-plates which are in tended for general use in laying railway tracks, and are intended to be interposed between the base of the rail and the tie to prevent the rapid destruction of the tie, must necessarily be of a character which will pre- 3 5 vent the lateral movementlof the rail on the tie-plate and the tie-plate on the tie,and this without loss of strength, lightness and resiliency in the plate, to avoid hammering and buckling, and without destruction of the fiber of the tie which would induce the water soaking and rotting of the tie as well as reduce the hold of the plate on the tie. To meet these requirements in railway tie-plates-or wear-plates,longitudinal ribs or truss flanges have been formed on the bottom of the tieplate and projections or abutments on the top or upper face of the. plate, and the common methods of producing such plates have been by casting or forging which in one case reduced the resiliency and added to the weight of the plate, and in the other increased unduly the cost of manufacture. To overcome these several objections, I produce a wrought metal bar (preferably rolled steel) having on one of its faces parallel ribs to form abutments for the foot flanges of a rail, whichribs are thereafter cutback at the ends a distance equal to the width of rib or flange required on the opposite face, and finally bend the plate at right angles to the ribs to form ribs. on the tie-face of the wear-plate-which method or its equivalent embraces the first feature of my invention. 7135 said method of procedure, I obtain a wear-plate or tie plate of wrought metal having upon its rail-face continuous parallel ribs or abutinents, and on its opposite face or tie-face parallel and continuous flanges or ribs at right angles to the first named ribs-and such tie-plate embraces the second feature of my invention.
I will now proceed to describe my-invention more fully, so that others skilled in the art to which it appertains may apply the same.
In the drawings A indicates a section of suitable width for a tie-plate which has been cut from a rolled bar of the same general form (a multiple tie-plate bar) having longitudinal ribs 0, a parallel with each other, and sufficiently far apart to accommodate a rail base and form a rail seat R. The width of the bar from which said section A is cut, will be equal to the required length of the tie-plate.
The next step in the process of forming the tie-plate consists in cutting off the ends of ribs a, a, as at b, b, so as to expose the plate for a distance equal to the width of the flange required on the opposite face of the plate, and at this time, or subsequentlythe spike openings 0 0 may be punched, which will leave the blank in the condition shown in Fig. 3. It is perfectly practicable to punch the spike holes 0 c and remove the ends of the ribs a, a, by punches or dies at a single operation but in such case the metal in the plate would be out out as indicated at dotted lines Fig. 3and this is not desirable as it would remove the truss fianges from the plate at the points of greatest strain, and render the plate more liable to bend or buckle.
Having obtained the blank in the form shown in Fig. 3, its parallel side edges are then bent up at right angles to the bottom face of the plate to form the truss ribs or flanges d d on the under side of the platethus obtaining a wrought metal tie-plate having on one face parallel abutments for the base of a rail, and on its opposite face and at right angles to the first named abutments or ribsa second set of flanges or ribs adapted to enter the tie parallel with the fiber of the tie-0r in other words-a tie-plate of the general character shown in Fig. 1.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, is g 1. The method herein described for forxning tie-plates which consists in first producing a metal plate having on one face parallel ribs, second removing the ends of said ribs for a distance equal to the width of the required flanges on the opposite face of the plate, and finally bending the edges of the plate at right angles to the body of the plate and also at right angles to the first named ribs; substantially as and for the purposes specified.
2. A tie-plate having on its rail face parallel ribs, and on its tie-face parallel ribs at right angles to the ribs on its rail face; substantially as and for the purposes specified.
In testimony whereof I atfix my signature in presence of two witnesses, this 25th day of May, 1893.
WILLIAM w. HOLMES.
