RAILWAY-Tl E PLATE.

SPECIFICATION forming part of Letters Patent NO. 514,466, dated February 13, 1894. Application filed Juno 2, 1893. Serial No. 476,368. (No model.)

To @Z whom it may concern:

Be it known that l, WILLIAM W. HOLMES,

a citizen of the United States, residing at Chicago, 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 had to the accompanying drawings, in which- Figure l is a plan or face View of a railway tie-plate embodying my invention. Fig. 2 is an end view of said railway tie-plate. Fig. 3 is a side elevation of said railway tie-plate; and Fig. 4 is a plan View of the blank before the projecting uncut edges have been folded over to form the abutments for the rail flange.

In Figs. 1 and 2 the dotted lines indicate the position of certain portions of the metal at different stages of the manufacture, While in Fig. 3, the dotted lines indicate the relation of' the railway tie and rail to the tie-plate when in use.

Like symbols refer to like parts wherever they occur.

My invention relates to the construction and manner of making that class of railway y tie-plates, or wear-plates, wherein the plate is provided with one or more truss or strengthening rlbs on its under or tie face, and a series of projections or abutments on its rail face,

and has for its object to simplify the form of the plate so that it can be readily and rapidly manufactured. It is now well understood that for this class of articles rolled metal is preferable to cast metal, because lightness with flexibility is thus obtained whereby the re-l siliency of the railway-tie is utilized and hammering of the rail by the passing loaded wheel is avoided. But in such tie-plates truss ribs are necessary on the under surface to stiften the plate and prevent buckling, while on the upper surface abutments are desirable to prevent lateral movement of the rail, consequently such tie-plates, in their more common forms, require to be either cast or drop forged.

In carrying ont my invention I first roll a plate (or a multiple plate bar) with one or more longitudinal ribs on one face thereof, 5o

and then cut a tongue or tongues from the body of the metal plate and fold the same on the opposite face of the metal plate to form abutments for the foot flange ofv the railwhich method of manufacture embraces the first feature of my invention. By said method or its equivalent I obtain a metal tie-plate having a longitudinal truss rib or ribs upon one face, and on the opposite face folds of the body metal which constitute abutments for 6o the foot ange of a rail-which construction 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 tie-plate having on its under surface one or more longitudinal ribs a, and upon its upper surface a series of abntments b which latter bound the seat C for the rail base and are formed by 7o the folded edges of the plate A.

D indicates spike holes for securing the rail and plate to the tie. In forming said plate I first roll a plate-or a bar composing a number of plates-with one or more longi- 7 5 tudinal ribs or iianges c, upon one face thereof; and if a series of said longitudinal ribs are formed they are preferably parallel with the outer edge of the plate and the outer ones are some distance within the margins or side 8o edges of the plate or bar, as indicated by the dotted lines Fig. 2, which project in the plane of the plate. Furthermore, while said proj ecting portions (shown in dotted line) may be of even gage with the body of the plate, they are preferably thickened up a gage or two so as to bear on the face of plate A when folded as indicated at w Fig-3.

Having obtained a plate of the character specified, I then out away from the side edges 9o thereof sectionsequal in length to the width of the rail base-as indicated at y fy-leaving the tongues or pieces ct projecting laterally, which tongues are thereafter folded down upon the face of the plate A, and the ends thereof bound the seat for the foot iiange of the rail forming the ab utments which prevent any lateral-movement of the rail when in po sition as indicated by dotted lines Fig. 3. I thus obtain in an expeditious and economical manner, with little labor or loss of material, a light, sti, and resilient tie-plate having truss ribs and rail flange abutmeuts and fulfilling all the requirements of this class of tie-plates.

I have herein pointed out what l deem to be the best form of plate, and manner of producing the foot iiange abutments, which border the rail seat on the upper face of the plate, but it will be evident to the skilled mechanic, that the folding tongues or pieces a may be obtained by simply cutting the plate without removing the section y; or that the folding tongue a may be cut from the body of the plate within the margin thereof Without departing from the spirit or scope of my invention. I do not, however,

recommend cutting the folding tongue in the body of the plate, as it has a tendency to reduce the strength of the plate and lead to its buckling.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isl l. The method herein described for making railway tie-plates, which consists in first forming a plate or bar with a longitudinal rib or ribs upon one face thereof, and then forming abutments on the opposite face of the plate by folding a section or sections of the plate upon itself; substantially as and for the purposes specified.

2. A railway tie-plate having on one face a longitudinal truss rib, and on the opposite face folds of the body metal which form abutments for the foot flange of a rail; substantially as and for the purposes specified.

In testimony whereof I affix my signature, in presence of two witnesses, this 25th day of May, 1893.

WILLIAM W. HOLMES.
