Our present invention relates to tie'plates for special purposes such as switches, turn-outs and guard rails. The present applicationis a'division of our co-pending application Serial No.

' 664,412 filed April 4, 1933.

In laying a track without switches or other I constructions the rails which intersect the tie plates supporting the rails, are very slightly inclined or canted so as to tilt the rails very slightly toward the center of the track. As these tie plates are all alike they may be rolled for use in large quantities. However, at switches or turnouts or other constructions in which one rail intersects or crosses another and in guard rails a number of special tie plates must be employed to support each of the rails involved in a position that changes for each tie. This requires the making of a number of special plates instead of I rolling a standard plate as can be done for a track section 'having no switches or similar constructions. a

I-Ieretofore these special plates have commonly been made with uncanted or horizontal surfaces and it has been necessary to provide a number of specially constructed or machined plates of varying inclination or canting between the canted plates and the uncanted plates so as to avoid a sharp change in position of the rails.

An object of our present invention is to provide a plate which may be of either canted or unmachined or machined and welded to form a number of special plates and in this way enable various'special shapes to be formed from a single rolled plate section.

The invention is illustrated in the accompanying drawings, in which- Fig. 1 is a plan view and Fig. 2 an end elevation of a special rolled plate which may be canted or uncanted and from which a number of special plates may be formed.

Figs. 3 and 4 are views of special shapes formed from the plate of Fig. 1.

Figs. 5, 6 and '7 are edge views of the plate of Figs. 1 and 2 showing the difierent arrangement of flat and canted plates. 7

Figs. 8 and '9 are side views of other special plates formed from the plate shown in Figs. 1, 2 and 5. V

Fig. 10 is a similar view of a canted plate formed from the plate shown in Figs. 6 and '7.

Fig. 11 is a plan view of another type of plate formed from the plates of Figs. 1 and 2 The rolled plate'shown in Fig. 1 and which may be canted in either direction or uncanted as outer face of the wider rib so as to provide ribs inner edge of the wider rib I 2 has been mashown in Figs. 5, Sand 7 has a base plate l provided with a narrow rib II and a wider rib I2, these ribs running crosswise of the plate at suitably spaced distances and being undercut at I3 and [4 respectively to form the bolt head receiving recesses. The plate ID with the ribs II and I2 may be rolled in the usual manner and cut to individual plates, and plates of various types may be formed by machining the inner or of diiierent spacings as required. The outer end of the plate is then sheared to form a symmetricalplate.

' The plate shown in Fig. 3 is one in which the chined to form a rib I5 of the standard width but spaced a greatervdistance from the rib ll than the inner edge of the original rib 1 12. In the event that the spacing between the ribs may be intermediate that of the inner edge of the original rib I2 and the edge of the rib. l5, the rib l2 may be machined from either or both edges so as to give any desired rib spacing.

In some cases it is necessary to have the ribs slant from a true perpendicular relation to the side edges in order to fit crossing tracks. In

, these cases the edges of the plate Ill may be sheared as indicated by the broken lines it and I! and then the edge of the rib I2 may be machined to provide the correct spacing. The plate I!) may also be used in forming the plate l8 shown in Fig. 8. This may be accomplished by cutting a groove I9 in the wide rib [2 to form two ribs 20 and 2|, then shearing the plate within the rib l I and welding it to a plate 22 having an undercut 23 to receive the flange of a rail 24. The ribs 20 and 2| serve to secure and hold a wedge 25 serving to wedge a brace 26 which is held downwardly onto the plate I8 by means of a bolt 21 secured in a rib 28 formed on the plate 22 before welding,

It will be understood that a canted plate may be used in a similar manner to form a plate similar to the construction of Fig. 8 buthaving a canting support for the rail 24.

In case a pair of rails, such as a main rail and a switch rail or guard rail, are to be supported in closely spaced relation, a plate such as that shown in Fig. 9 may be required. In this case a plate I0 may be sheared within the narrow rib H and then welded to a second ribbed plate outside the narrow rib as, for example, at 29 in Fig. 9. One of the wider ribs may then be grooved V as at 30 to provide a pair of closely spaced ribs 3| and 32 and the other wider rib may be similarly as grooved or may be machined to form a single narrower rib such as the rib 33.

It will be understood that in this case also canted plates of the construction shown in Figs. 6 and 7 may be employed so as to cant the rail supporting surfaces of the special plate in either direction as required. I

A canted plate formed from the rolled plates of Figs. 6 and '7 is shown in Fig. 10 in which the plate of Fig. 6 is sheared on a line 34 and another similar plate is sheared on the line 35' and then the two plates are welded ontheweld=36 of Fig. 10.

Thereafter the wider rib. l2? may? be planed away as indicated by the dotted. lines of Fig. 10 to provide the narrow outer rib 38. Or, if necessary, two plates suitably sheared may be-welded as at 36 and 31 to a broad rib 38.;as'indicated in Fig. 10, provided it is'necessary to form a plate having a rail supporting surface wider or, narrower than that between the ribs l l and. In

constructing a plate suchas that of; Fig. 10, the

ribs 38 and 39 maybe planed toform two track supporting surfaces 40 and 4|. that diverge or lie at an angle to each other.

By using a canted plate-in the above manner it will be possible to form plates in which the cant of the rails may be carried directly through the switch orturn-out or other construction, and thereby avoid the necessity of transition plates of graded cant.

The above are merely illustrative of the various ways in which special plates may be made from a rolled section by providing on such section spaced ribs one at least of which is of suflicient width to permit machining'so asto enable the distance between the ribs to be modified, or double ribs to be formed, or various combinations of plates to be made and-the rib spacings thereof adjusted.

Various modifications may be made by those skilled in the art without departing from the invention as defined in the following claims.

What we claim is:

1. A method of forming rail supporting tie plates which comprises rolling a plate with spaced transverse ribs, one of said ribs being wider than the other, machining said wider rib from a side edge to the widthof the' narrower rib and to a spaced distance-therefromand shaping said plate to a desired dimension.

2; A method of making rail supporting tie plates of selected dimensions which comprises rolling a plate with spaced transverse ribs, one of said ribs being. materially wider than the other, shearingtheside-edges of said plate to an oblique angle to said ribsand machining said wider rib to provide a selected'distance between said ribs.

3. A method of forming rail supporting tie plateswhich comprises rolling a plate with spaced transverse ribs, one of said ribs being wider than the other, shearing said plate within one of said ribs and welding it end-to-end to a similar unsheared plate.

4. A method of forming rail supporting tie plateswhich comprises rolling a plate with spaced transverse ribs, one of 'saidribs being-wider than the other, shearing said plate withinone of said ribs. and welding it end+to'-end to a similar unsheared plateand machining said wider ribs to a selected rib width and spacing.

5. A method of forming rail supporting tie plateswhich comprises rolling a plate with spaced transverse ribs, one of said ribs beingwider than the other, shearing said plate within one of said ribs and welding it .end to end to a similar unsheared plate, and machining said wider plates to a selected rib width and spacing and having the side faces of the central rib extending in a hori-- zontal angle to form diverging track supporting surfaces.
