Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed September 18. 1905. Serial No. 278,933.

To ctZZ whom it may concern.-

Be it known that I, ETHAN I. DonDs, a citizen of the United States, residing at Pullman, in the county of Cook and State of Illinois, have invented certain new and useful I'mprovements in Corner-Stakes for Cars and Method of Manufacture, of which the following is a specification.

To provide an improved form of car-stake which shall combine great strength, pleasing appearance, and economy of manufacture, I have invented the form of stake and the method of producing it hereinafter described and claimed. My invention relates more particularly to metallic corner-stakes for railway-cars, but is not limited to such application, and by my method I am enabled to manufacture two or more of such stakes simultaneously. When two stakes are to be made from a sheet of metal, I e'mbo ss or press out of the plane thereof two hollow ribs and bend up the outer edges of the sheet to form flanges, the two stakes'thus produced. being subsequently cut apart, so that each has a rib and angularly-disposed flanges.

In the accompanying drawings I have illustrated the method of manufacturing these stakes and also the stakes themselves.

Figure 1 illustrates a cross-section of the dies employed in pressing a sheet of metal so as to form two of my improved stakes, and shows a sheet of metal between the dies. Fig. 2 is an end view of the sheet of metal after it has been pressed by the dies. Fig. 3 is an edge view of one of the stakes. Fig. 4 is a horizontal cross-section of a portion of-a car and corner-stake and illustrates the manner in which the stake shown in Fig. 3 is appliedto the corner of the car. Fig. 5 shows the application of the reversely-formed stake to the other end of the car, and Fig. 6 is a perspective view of the sheet of metal after it has been operated upon by the dies.

Referring to Fig. l, the lower die 10 has a central horizontal surface 11 and two separated vertical surfaces 12 and 13. Between the central horizontal surface 11 and the vertical surface 13 is a tapered transverselyrounded projection 14, and between the cen tral horizontal surface 11 and the vertical surface 12 is a tapered transversely-rounded depression 15. The upper die 16 is provided with a central horizontal surface 17 and vertical surfaces 18 and 19, together with a ta pered transversely-rounded projection 20,

adapted to lit in recess 15, and a tapered transversely-rounde l recess 21, within which projection 14 is adapted to fit. A rectangular sheet of metal 22 is placed between the dies which are subsequently brought together, pressing the sheet into the shape illustrated in Fig. 6. Sheet 22, when thus formed to shape, has a central horizontal portion 23, with two tapered hollow ribs 23 and 23 pressed out of the plane thereof in opposite directions, the narrow ends of the ribs pointing in opposite directions, the sheet also having the vertical flanges 24 and 25, the outer edges of which are somewhat concaved by the stamping operation which draws in the metal to form the ribs. It will be seen that the ribs 23 and 23 are tapered not only in width but also in thicknessthat is, the amount they project from the plane of the sheet. To cut the sheet into proper shape so as to form two corner-stakes, it is sheared on line 26 and the vertical flanges 24 and 25 are trimmed on lines 27 and 28. This produces two reverselyformed corner-stakes, each with two angularly-disposed flanges and an integral hollow tapered rib.

Fig. 3 is an edge view of one of these stakes. The same is secured to the corner of the car by means of rivets or bolts passing through holes in the stake flanges and through the end of the car 29 and side of the car 30, preferably engaging upon the inner side an angle-bar 31. It will be noted that the two stakes 32 and 33, formed simultaneously by this process, are not alike, but are, in fact, reversely shaped, being adapted for use on the opposite ends of the car, as shown in Figs. 4c and 5.

Although I have illustrated and described a process of making two stakes simultaneously, it will be apparent that by properly shaping the dies any number of such stakes may be produced by one stamping operation, the alternate ribs projecting in opposite directions from the plane of the sheet and having their narrow ends extending toward the opposite ends of the sheet.

It will also be obvious that other minor changes may be made in this process or in the stakes themselves without departing from the substance of the invention as defined in the appended claims.

This patent is intended, to embrace only so much of the disclosure made herein as is covered by the claims.
